What brand of LED bulb is good in quality?
Look at the bulb of the bulb. The so-called bubble shell refers to the transparent glass shell in front. In incandescent lamps, all are made of glass. But in LED bulbs, though they can be made of glass, they rarely do.. Because the LED bulb weight than incandescent lamp 5 times or more, if made of glass, fell on the ground, it broke the possibility of large. As a result, more LED bulbs are made of plastic to prevent them from breaking. And the LED bulb went out because the heat from the radiator, so the bulb Everbright is visible light, infrared heating has little, so the use of plastic to make foam shell will not damage due to heat.
View brightness. Incandescent lamps usually only talk about wattage instead of lumens, but LED bulbs can count in watts, but wattage does not represent the number of lumens due to the continuous development of LED's luminous efficiency.
The price of these lamps is very low, but the quality is not guaranteed at all. The purpose of this article is to teach consumers to distinguish the quality of LED bulbs on the market so as not to be cheated. So, which brand LED bulb is good, choose a good brand, first of all should first understand how the quality of its products
What brand of LED bulb is good? LED bulb has replaced the ordinary fluorescent lamp and incandescent lamp gradually, with the market demand is more and more big, and the production of the LED lamp threshold is very low, so a lot of small family workshop also began assembling production of LED lamps, the technical content is low, without testing and certification of products, also began to circulate on the market.
See shape. Incandescent bulbs are usually pear shaped, so the bulb should be pear shaped. That's easy to do. But incandescent lamps are all glass products, and because LED requires heat radiation, aluminum alloys are usually used as housings, because of their low cost, easy processing, and good thermal conductivity. The size of the aluminum shell determines the heat dissipation and also determines the life span.
