The analysis of the LED panel lamp cost

   The LED panel lamp cost is determined by various factors. Our simple analysis for everyone.
   One, LED lamp bead cost. This is a relatively fixed, depending on the technology level of the whole industry, but also the general customers are purchasing Taiwan or American brand, price cannot control. Even if the purchase price is different, the gap is small. So, want to in this part of reduce cost, more difficult.
   Two, border. The border is usually aluminum alloy material, which belongs to the futures prices, relatively large changes, according to the current market, basically belongs to the bullish trend.
   Three, the driving power supply. LED lighting panel power supply, a mature industry, the price also is more transparent, the difference lies in the customer requirements of high or low and there is a little gap. But now there is a fireproof ultrathin PC material, can do 1.0mm fireproof, either through the UL certification, but also can reduce the weight of power effectively, and improve the flexibility of design. In improving the performance of the products, reduce the cost of.
   Four, the light guide plate. The light guide plate has size and thickness of different, generally is 4mm and 6mm. 6mm mature, light efficiency in general can do more than 85%, the price is relatively expensive, occupied the whole lamp at least cost more than 25%. 4mm the price will be cheaper than the 6mm a little bit of money, but 4mm technology is not very mature, can do the manufacturers, not many.
   Five, the diffusion plate. The diffusion plate material determines the price. Currently on the market there are PC and PMMA two. PMMA was at least 30% cheaper than PC. But there is a drawback, is PMMA relatively brittle, the thinnest can do 2mm, and PC to 1.0---2.0, and the toughness is good, the assembly is convenient. And can do fireproof grade 94V0 and 94V2.

The purchase method of LED tube

    Here, we introduce the purchase method of LED tube for you.
    Choose the appropriate color temperature. If the LED tube installation position is higher, can choose the color a little higher, such as: 6500K--7000K. So, LED light effect is relatively high. If, with the lower position, should choose color temperature low, such as the color temperature in the 5500K--6000K. The light is soft.
    Purchase LED tube also need to consider the appropriate power. Energy consumption of LED tube the same, the luminous flux vary greatly, selection of high quality, large luminous flux LED tube to replace the traditional fluorescent lamp, can be properly install less. Not with the traditional fluorescent lamp 1:1 substitution. In this way, more energy saving.
    Choose the appropriate appearance: General LED fluorescent lamp in the user idea still stays in the stage of the traditional fluorescent lamp. So, no matter what the situation, require light and the traditional fluorescent lamp the same. Manufacturers in the LED tube plus soft light plate, the light looks like with the traditional. In fact, soft board when there is a loss of light energy. Generally between 15-30%. If the installation position is higher, eyes not easy often irradiation, can consider to use a transparent cover, so, can choose to power small LED fluorescent lamp, will be more energy efficient.

LED downlight and spotlight biggest difference

     LED downlight and spotlight biggest difference is emitting angle is different, resulting in differences in structure!
     LED down light: mainly used to provide uniform light irradiation range. Viewing angle Downlight are generally larger, usually around 120 degrees, generally using acrylic mask, so you can get uniform light, soft light without glare.
     LED spot light: mainly to highlight the key object through a small angle light, such as the television background wall, murals, ornaments, commodity etc.. Or increase the chiaroscuro of space, creating an atmosphere, such as big-name clothing flagship store, very strong chiaroscuro. To achieve this effect, light angle of spotlights generally small, usually 30-60 degrees. Therefore, even though it and similar downlight has the same power, the same total light irradiation, but the area is small, the brightness is high. Structurally, the spotlight is often reflected by the lens or bowl, to achieve small angle condenser, and can usually adjust the illumination angle, so when you install, you can adjust the irradiation object as needed.

LED bulb manufacturers should standardize what points?

      Now LED lamp market matures, the market is also growing up, so there are some LED manufacturers shoddy, therefore, the MIIT bulletin solicitation "led bulb performance requirements." LED bulb manufacturers based on their own experience and the standard production, that the performance of LED bulb lamp must meet the following requirements, for everyone to discuss.
      1, security: the LED bulb lamp safety should be put in the first place to consider. At present, China led bulb lights is used in aluminum metal shell, this is the most users is most likely to exposure to parts, but the metal is easy to conductive, aluminum shell led bulb lights existence of security risks of electric shock. Therefore, it is best of LED lamp radiating seat insulation to be improved, such as the use of ceramic and plastic insulating material, in order to ensure foolproof.
      2, life: a LED lamp is characterized by a long service life, but some LED bulb manufacturers because of price competition, not use of normative materials, or professional degree is not enough, in thermal design and drive circuit design is unreasonable,  do so out of LED bulb life and not up to standard, this implicit the bad will cause damage to the interests of consumers. Therefore, should be on the service life of the LED lamp has a reasonable limit.
      3, the optical performance requirements: Some LED bulb manufacturers to lower the color to improve LED light flux, making the color performance level is low, even lower than energy-saving lamps, which is unreasonable,therefore, suggested that the LED manufacturer of light color and CRI to norms, such as home and commercial space LED bulb should be defined in Ra> 80, In addition to a diverse range of light color should be regulated, such as white light, neutral light range, and so on.
      The above performance criterion not only can be used for LED bulb lamp, some can also be used for other LED lamps, such as LED ceiling lamp, LED downlights performance norms.

LED spot light color temperature selection

    LED spotlight is generally white light, but white light color are also different, terminology is the "color temperature" to express, from 1800K - 7500K. About 3000K color temperature often referred to warm white (often confused with light and yellow), 4000K is called the natural white, 5500K - 6000K is called the white, 6500K or more is called cold white. In fact, choice of color temperature is very simple, because all things including the human, is the life in the sun, the sun light in the morning is warm white, noon is white, night back to the warm white. Therefore, LED spot light color temperature selection, can with sunshine as the reference.
    In home lighting general choose warm white or pure white light, if there is a natural white, of course the better. Warm white is characterized by warm, pure white characteristic is bright. In the home  has ceiling lamps, there are downlights, spotlights, wall lamps, strip light and other auxiliary lamps lighting, preferably pure white, warm white with use.
    It is worth mentioning that has now emerged intelligent dimmable LED spot light, this is mainly because the advantages of LED, a lamp can bring up the pure white, warm white, natural white. This is the incandescent lamp and fluorescent energy-saving lamps can not compare, this is the advantage and charm of LED lamp!

China led bulb lamp in North Korea hot

    Recently China led bulb lamp in North Korea hot, more and more North Korea people panic buying Chinese manufacturing LED bulb lamp. Although LED bulb price is expensive, but compared with the traditional incandescent lamp, LED lamp has high efficiency, energy saving, which for a severe power shortage countries is undoubtedly the best choice. So, a lot of the North Korea people are willing to choose the high price but can work properly at low voltage LED bulb lamp.
    Because North Korea electric power shortage, cannot provide 220V voltage required for the normal work of the general household electrical appliances, but the LED lamp can light normally under the condition of low voltage, so LED lamp sales soared in North Korea. In the summer peak electricity, the North Korea households voltage is only 170V, lower in winter to 100V. The incandescent lamp can not provide normal lighting required at voltages below 220V, but the LED lamp is different, even if the voltage is lower than 70V, it can still normal lighting. So, although China led bulb lights price higher than incandescent lamp two times, the North Korea people still willing to buy LED lamp.
    Another advantage of LED lamp is long service life. High power LED lamp life of up to 50000 hours, the incandescent lamp life of only 2000 hours, fluorescent lamp life 15000 hours, compared with them, LED lamp life advantage prominent.

What is the difference between LED downlight and LED spotlight

     LED downlight and LED spotlight a lot of people are confused, don't know these two types of lamps have what distinction, should be applied to Home Furnishing what position, and the application effect is what different. What is the difference between LED downlight and LED spotlight? We can usually be distinguished them from the application location and the application effect.
     1. Distinguish from the product performance:
     LED downlight is a lamp is embedded into the ceiling, the light is downward irradiation. Belongs to the directional lighting, only its opposite to by the light, the light more focused than ordinary lamps, usually used for general lighting or lighting. With the continuous development of LED technology, the LED downlight life is generally more than 50000 hours.
     LED spotlight is embedded in the ceiling or wall. It is the lighting products a light high concentration. It is usually light to the specified destination. Through the light used to emphasize important points. Because the LED spotlight will produce high temperature at work, so be sure to select high-quality products in the purchase of LED spot light, otherwise it will create a security risk. The LED spotlight is mainly used for various types of commercial space lighting and architectural lighting. At the same time, spotlight is also divided into low and high pressure two, suggest that consumers the best selection of low voltage spotlight, reason is the low voltage spotlight relatively long service life, high light efficiency. Spot light effect to the power factor to determine. Quality spotlights the power factor up to 0.99, but the price is much more expensive.
     2. Distinction in the application of location:
     Most LED downlight are installed in the ceiling which requires 150mm above the ceiling to be installed. Of course, there are external type of LED downlights. Usually in no position dome light or chandelier installation of LED downlights, light and soft than spotlights.
     LED spotlights can be divided into several categories: rail, point hanging and embedded variety. Spotlight also with transformers and transformer without. Phase in the ceiling are embedded. LED spotlights specific performance on key irradiation position such as: TV wall, Logo backgrounds, and some important jewelry and other ornaments.

LED light panel manufacturers need to pay attention to problem

     The development and maturation of LED technology, the LED lamp products emitting efficiency improvement and the decline of the price, the promotion and application of LED lighting products also have a good prospect. In this regard, the LED standard component in the management of innovation, establish the management system of strict.
     Even so, affect the healthy development of the LED industry problems still exist. LED light panel manufacturers need to pay attention to problem are as follows.
     First, technological innovation capability is weak, the chip as the representative of the high-end products are still mainly in the hands of foreign enterprises. For example, China's existing more than 980 Taiwan MOCVD machine are imported, in downstream key equipment mainly imported, to industrial growth, the hidden trouble.
     Secondly, the lack of leading enterprises lead the industry. A large number of small and medium-sized enterprises occupy the low-end market, make price war greatly, the product quality is worrying. China's large scale led light panel manufacturers operating income of only billions of dollars, and the international giant annual sales of tens of billions of dollars compared great difference.
     Finally, unfair competition and capacity expansion, disrupted the original order in the market, the need for policy adjustment.
     To solve these problems, LED enterprises can make measures, in order to strengthen their competitiveness. The importance of product innovation and R & D investment, improve the technological content of products, in some technical aspects of key and foreign manufacturers to seek cooperation, also can cooperate with local enterprises, reduce dependence on foreign technology. China's LED enterprises should develop its own scale and product quality, only quality products can survive in the fierce competition in the market, gain a strong development.

The importance of the led flat panel lighting power supply

    Popular in the LED panel lights at the same time, an important component of its -- drive power has been paid attention to. Because the drive power quality LED panel lamp directly determines the reliability of the LED panel light, so with the development of LED panel light industry, LED driving power supply is gradually mature. Here we introduce you the importance of the led flat panel lighting power supply.
    Since LED is a sensitive semiconductor device, but also has a negative temperature characteristic, therefore in the application process need to be stabilized and protected the, resulting in a concept of drive.
    LED requirements for driving power supply is very strict, LED panel light can not be directly connected to the AC mains. LED is 2 to 3 volt low driving voltage, need to transform a complex circuit design, LED lamps with different purposes, to be equipped with the power adapter of different.
    The international market of foreign clients on the LED panel lamp driver power conversion efficiency, effective power, the precision of constant current, power life, electromagnetic compatibility requirements are very high, the design of a good power supply must be comprehensive consideration of these factors, because the led lighting panel power supply are as important as the human heart.
    First is the driving circuit of whole life, especially the key components, such as capacitors under high temperature service life directly affects the life of the power supply. Second is the LED driver should be converted to challenge higher efficiency, especially in the high-power LED drive, because the output of the power there is a part of dissipated as heat, power conversion efficiency is too low, affected the play LED panel light energy-saving effect.

What are the advantages of 15 watt led down light

    LED downlight and ordinary lamp, are composed of two parts, one part is the lamp holder, is part of a light source, the light source is LED. What are the advantages of 15 watt led down light?
    Long working life: a semiconductor solid-state light-emitting device as the LED, have a longer working life than other light source. Its brightness half-life usually one hundred thousand hours. Such as the use of LED to replace the traditional automobile lamps, then its life will be much larger than the automobile body life, is life without repair and replacement.
    Low power consumption: LED is a low voltage device, so the same brightness, the power consumption is minimal, which can greatly reduce the energy consumption. On the contrary, with the development of technology and materials in the future, will have a higher luminous efficiency. People made a calculation, if the lighting of Japan use LED instead, can reduce the two large power plants, is very beneficial to the environment protection.
    Fast response time: 15 watt led down light can generally be response in tens of milliseconds, which is better than other light sources. Made by the LED auto high brake lights in the state of high speed, greatly improves the safety of automobile.
    Small volume, light weight, resistance to fight: This is the inherent characteristics of semiconductor solid device. Color LED display production of various types of clear and delicate.
    Easy to dimming, palette, controllable: the LED as a light emitting device, can control the brightness by changing the current flowing, and can also be adjusted by different wavelength LED configuration to achieve color changes. So LED is composed of light source or display, easy by electronic control to achieve the requirements of various applications, and IC computer in compatibility with all difficulties.

How to identify the quality of e27 led light bulb

   The LED bulb has been gradually replace ordinary fluorescent lamp and incandescent lamp, with the needs of the market is more and more big, and the production of LED lamps, the threshold is very low, so a lot of the small family workshop also started to assemble LED lamp, the technical content is low, not through the testing and certification of products, also began to circulate on the market. The price is very low, but the quality is not guaranteed. So how to identify the quality of e27 led light bulb, consumers can be considered from the following aspects:
   First, look at the brightness. If the incandescent lamp for lumen is calculated, the luminous efficiency of incandescent lamps in the 7.5-12lm/W. Watts is more efficient. Power conversion specific incandescent lamps and LED light bulb:
3W LED bulb: the actual power is about 4W, to replace the energy-saving lamps of 12W and incandescent lamps of 30W.
5W LED bulb: the actual power is about 5.5W, to replace the energy-saving lamps of 20W and incandescent lamps of 45W.
7W LED bulb: the actual power is about 7.5W, to replace the energy-saving lamps of 30W and incandescent lamps of 75W.
   Second, look at the shape. Incandescent lamp is usually pear shaped, so the e27 led light bulb should also be pear shaped. It is very easy to do. But the incandescent lamp as a whole glass products, because LED need to heat, usually made of aluminum alloy shell, because of low cost, easy processing, and good thermal conductivity. Aluminum shell size, determines the radiation, but also life.
   Third, look at the bulb glass shell. The so-called bubble shell is a front transparent glass shell. The incandescent lamp, are all made of glass. But in the LED bulb lamp, although it can be made of glass bulb, but few have done so.. Because LED bulb than incandescent lamp 5 times more weight, if made of glass, fell on the ground, on the great crash likelihood. Therefore, more LED bulbs use plastic shell, to prevent broken. But LED bulb lamp because the heat went out from the radiator, so the bubble shell Everbright is visible, there are few heating infrared, so the use of plastic to make the bubble shell can not be damaged because of no heat radiation. Usually the bubble shell requirements are as follows: 1 with high light transmittance, high diffusion, no glare, no light; 2 light hidden better (as far as possible not to see the LED lamp); 3 light transmission rate of more than 90%; 4 with the high resistance; 5 with high impact strength;
   Fourth, look at the lights, the famous brand: Epistar (Taiwan), Samsung (South Korea), CREE (America), Osram (Germany) and other imported beads. We can see the product specification on the packaging, usually of high quality LED bulb lamp use imported beads.
   Fifth, after sale service. Based on the above points, we can judge the quality of a LED bulb lamp, combined with the market price comparison, we can find a good China led bulb lights.
