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.

Characteristics of led lighting panel power supply

  LED panel light because of its energy-saving, environmental protection, adjustable light, low energy consumption, long service life and is loved by people, but in the LED panel lights, there is an easily overlooked important constituent, is the power of LED panel lamp.
  LED panel light's power plays an important role in the work of the LED, it can regulate the stability of current, filtering interference protection circuit security, greatly affects the LED panel lamp performance and life.
  In the current market, the characteristics of high-quality led lighting panel power supply:
  1. The new modular power supply IC
  Boost DC / DC converter is a high efficiency, but the ripple and noise voltage is large, low-dropout linear regulator low efficiency but noise is minimal, consisting of a combination of the two dual output power supply IC can solve the efficiency and noise issue.
  2. High output voltage accuracy
  Output voltage accuracy is ± 2 ~ 4%, there are a lot of new power IC accuracy is ± 0.5 and ± 1%; and the output voltage temperature coefficient is small, typically ± 0.3 ~ ± 0.5mV / ℃, and some can reach ± 0.1mV/ ℃ level. Linear adjustment rate is generally 0.05% ~ 0.1%/V, some up to 0.01%/V; load adjustment rate is generally 0.3 ~ 0.5%/mA, some up to 0.01%/mA.
  3. Low operating voltage
  The LED panel light power supply voltage general is 3 ~ 3.6V. There are some lower working voltage, such as 2, 2.5, 2.7V; there are also some working voltage is 5V, and special use a 12V or 28V voltage source.
  4. Perfect protection measures
  Power IC has perfect protection measures, which include: output over-current limit, thermal protection, short circuit protection and reverse polarity battery protection, the power supply to the safe and reliable work, not easy to damage.
  5. Small package size
  In recent years, LED panel lights are used SMD devices, power IC is no exception, there are SO packages, SOT-23 package, μMAX package and the smallest package size SC-70 and the latest SMD package。The power accounted for less and less space.
  6. Low operating current
  As the current most LED panel lamp is less than 300mA, so the 30 ~ 300mA power in species and quantity accounted for the larger proportion.

Thermal properties of e27 led light bulb

      Bulb light due to size restrictions, so the thermal properties of e27 led light bulb should be improved. No matter what kind of radiator can only rely on the convection and radiation in two ways to dissipate heat into the air, and these two kinds of heat and its heat is proportional to the area of. The bulb lamp radiator area limitations, so it is difficult to heat than 7-9W. According to the LED light effect at present, lumen it is equivalent to 60W incandescent lamp. With LED light efficiency increased year by year, I believe there will be the same size but can replace incandescent lamps with 100W.
      Radiator material at present most of the use of aluminum alloy, because of low cost, easy processing, and good thermal conductivity. But recently there has been a lot of insulating plastic radiators and ceramic radiator, the radiating effect is not bad. Because the final heat mainly by convection and radiation. Convection is completely determined by its shape and area. Radiation and radiation related materials. Oxidation is an important way to improve the heat radiation of metal materials. The conductive plastics do not need any radiation coefficient of oxidation treatment can achieve very high. So as long as the appearance and the metal radiator, the convection and radiation effect and the metal heat sink effect is the same. But the heat conductivity and certainly not metal, so the overall cooling effectiveness will be less. But if you do it as thin as possible, wall plus a layer of metal, can put the unfavorable factors of the low heat conduction to a minimum. Now has a coefficient of thermal conductivity is greater than 20 w/mk plastic, but the price is relatively high. And plastic radiator ceramic radiator. But its thermal conductivity can be made higher cost is much higher, of course. The biggest advantage of plastic and ceramic insulation, so even if the non isolated power supply is also easily through the safety inspection.
      In addition, in order to improve the heat dissipation effect of e27 led light bulb constant current drive power, usually have to add thermal sealant to replace the poor thermal conductivity of air. Another method is to punch in the radiator, so that the flow of air. But there will be waterproof problem.

The led light panel manufacturers how to seize the market

     Last year, the global LED lighting market reached $ 13.7 billion, is expected this year, this figure will break 350-400 billion dollars, made clear the enormous size and growth space LED lighting market.
     In the LED industry development of the times, both a good time, but also a difficult era to grasp, because of the rapid growth of large-scale development of space, resulting in fierce competition in the LED industry, each LED lamp enterprises to survive and continuous efforts.
     The led light panel manufacturers how to seize the market? First of all, the technology is still the core of the development of LED lighting industry, LED manufacturers have to improve the technical level of LED products, product quality assurance, at present, due to intense competition, the quality of LED lamps on the market uneven, many low-end products into the market, lead to advantages of LED light can't be reflected, in addition, some enterprises use super low price to sell products, product cut corners, lower product quality, which will disrupt the entire market of LED lights, which are also self-smashing brand. Such enterprises will eventually be eliminated.
     Secondly, The led light panel manufacturers to survive in the LED lighting market down, must paste into the market, identify the location, good product pricing, is the production of high-end type or economical, is for dealers or for the project, these all need to be considered, a good location, in order to make accurate market positioning, looking for enterprise its development road.
