Nichia developed intensity white LED module 1000LM

Recently, Nichia developed intensity white LED module of 1000lm, the installation area is 40mm * 40MM * 10mm. When the output intensity of 1000lm is 30W, the luminous efficiency is 33lm/W, the maximum input power is 50W. The mounting substrate is provided with a plurality of blue light LED chips and a yellow fluorescent material is combined. Nichia has not disclosed details of the module specifications, and production schedule.

Generally, with the increase in output power, the internal temperature of the white LED module will rise and the luminous efficiency will decrease. In addition, if the size of the LED chip will increase the electric field distribution inside the chip, it will lead to decreased luminous efficiency. To solve this problem, Nichia said, "at present can not disclose details, but through the electrode structure and encapsulation technology of LED chip is improved, can improve the luminous efficiency".

Nichia has also released the luminous efficiency of white LED module 50lm/W. The diameter of the shell of the 5mm type package, when applied +3.6V voltage current of 3.6lm is strong for 20mA. Combination of 300 micron x 300 micron blue LED chip and yellow fluorescent material. The company will use the white LED module to do lighting equipment booth.
