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 ceiling light lamp beads

      About the use of LED ceiling light lamp beads. Power greater of Ceiling Light than 30W  generally use 1W LED lamp beads, power is less than 30W Ceiling Light generally use small power LED lamp beads (eg 3020,3014,3528, etc.). Recommended for low-power SMD LED, easy to heat, but also improve the luminous uniformity.
      Lamp beads can be arranged according to their shape, such as square led ceiling light, lamp beads arranged in a square; If the shape is round, then arranged in a circle. Even so, the arrangement of lamp beads still there are many ways, the internal structure of a typical LED ceiling as shown.

      In the picture, has two ring LED lamp beads on the annular plate, it is the use of 23 0.4W type 5730 LED lamp beads, total power is 18W.

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.
