Japan CITIZEN electronics has developed far more than 10 thousand LM white LED

CITIZEN electronics developed a maximum brightness of 10 thousand 7675lm white LED "CLL-050 series". The brightness of each white LED is far more than 10 thousand LM, "Department of the world for the first time" (the company). When the brightness of the maximum input power of 183.9W, luminous efficiency of up to 96lm/W (shell temperature of 25 degrees C continuous lighting). 300W mercury lamp. The average color rendering index (Ra) was 65 and the color temperature was 5000K. The company's original production of white LED, the maximum brightness of its large amount of light products for the 4390lm, which is increased by 4 times. In the range of 2700 to 5000K color temperature is also available in the Ra for the high color rendering model of 80. Ra is 80 of the product with Ra compared to the brightness of the product is low, but the brightness of the color temperature of 3000K is more than 10 thousand and reached a of 10 thousand 4290lm.

CLL-050 series of external dimensions of 38mm * 38mm, thickness of 1.4mm. Input power range of 24.6 ~ 183.9W. The luminous efficiency of Ra65 variety is about 117lm at 24.6W input. The central part of the square package is provided with a circular luminous surface. The structure of the utility model is characterized in that a plurality of blue LED chips are arranged on the aluminum substrate, and the whole structure is covered by a resin with fluorescent material. Also improved the configuration of the blue LED chip, the original is in a circular light-emitting surface was arranged in a square, this is changed into a circular configuration. In this way, the installation of white LED on the instrument, is not easy to form a spot.

In addition to the CLL-050 series, CITIZEN electronics also released a maximum brightness of 590lm, 1970lm, 5780lm and 10 thousand 2915lm of the different packaging of the 4 series. 5 series of products, including the CLL-050 series, covering a range of 95 to 10 thousand 7675lm, can deal with a wide range of requirements from 10W incandescent bulbs to 300W mercury lamps.
