Light effect of LED lamps

In order to save energy, countries have set a ban on the production and sale of incandescent lamps.

A, LED bulb lamp

LED is a kind of mercury free, light effect is much higher than the "energy-saving lamps" lamps, it is the real energy-saving lamps. It is bound to become the mainstream lighting products. But it has appeared lamps of various shapes, including can replace incandescent lamp bulb lamp, LED lamp to replace the fluorescent lamp, LED ceiling lamps, LED lamp, LED lamp, PAR. In order to save energy, countries have set a ban on the production and sale of incandescent lamps.

Australia: 2010

EU, Taiwan, Canada: 2012

Korea: 2013

Japan: 2012 (high energy)

United States: 2014 full ban

China: 2016 full ban, in the 2014, 10, 1 ban on imports and sales of more than 60 watt incandescent lamp

Light effect of LED lamps

It is estimated that in 2014 due to the United States and other countries to ban incandescent bulbs, the global LED bulb demand growth of 86%. Therefore, we will focus on the use of incandescent bulbs to replace the LED bulb. In order to make it easy for users to accept, the LED bulb is specially designed to be similar to the shape and size of the incandescent lamp, and the lamp holder is exactly the same. At present, the number of Watts consumed by LED is used as the main index. This has created a big loophole, some light bulb bulb, hit 1 yuan per watt indicators, and slightly better bulb lights hit the target of $2 per watt. This is a very unscientific price index. Because of some low light efficiency bulb, power consumption is very high but not very large flux, but also known as the big number, it sounded like a good lighting, in fact it is crudely made products. The correct indicator should be its luminous efficiency. This is a question to be discussed in this paper.

Two, LED light effect

The unit of luminous efficiency is the number of lumens per watt, which is expressed in lm/W, which is the unit of luminous flux. Most people may not quite understand what is luminous flux. All we need to do is to figure out the lumens of incandescent lamps with different wattage. So as long as the LED bulb light and the number of lumens emitted by a certain number of incandescent bulbs, the bulb can replace the incandescent lamp. This is one of the easiest ways people can accept. So now the packing box of American and Japanese bulbs on the very word mark can replace the incandescent lamp wattage, although this number is W, but the number of Watts consumed and it is not LED, but the number of watt incandescent lamp can be replaced, but the old people understand at a glance.
