From 2013 global LED production value point of view, Japan, Korea, Taiwan and mainland China each accounted for about 20%. It should be said that the domestic LED output is growing rapidly. But relatively speaking, at the same time, rapid growth in domestic output, LED level of technological development is more general. On the contrary, foreign LED output growth in general, technological development very quickly.
The main technical indicators LED luminous efficiency. According to reports, several major companies in the world have more than laboratory level LED package 200lm / w, which the United States Cree's laboratory level reached 303lm / w. We know that the goal of industrialization plan is to put the United States SSL LED luminous efficiency to 250lm / w, and to reduce the price to $ 0.5 / klm. And its current level of industrialization of 120lm / w ~ 150lm / w, the price of about $ 3 / klm.
LED lighting on the level of the whole lamp look, Cree, Philips and other companies products have more than 200lm / w, straight tube lamps Osram products reportedly reached 215lm / w. However, the current level of the domestic industry has only 100lm / w ~ 130lm / w, of course, the price level is relatively low.
