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.
