Neon fluorescent lamp COB light efficiency exceeded 160lm/W

Abstract: LED as a new light source, are increasingly being integrated into people's lives, it can not be divorced from the development of demand for lighting. Compared to traditional light sources (such as fluorescent lamp and incandescent lamp), LED is nearly 5-20 times higher than the traditional light source when it is close to the theoretical conversion efficiency. But because the LED lamp is cheaper than traditional lamps of the high price of 5-10 times, so that the LED lamps are mainly used in commercial lighting and public lighting and other fields, LED lamps Gao Guangxiao, commercial lighting and public lighting in the field of high reliability, so the development of new light source imperative highly effective and reliable, safe and durable. For LED lighting market of LED lamps with high luminous efficiency, industrial packaging R & D center currently developed COB 160lm/W fluorescent lamp, LED lighting to meet the high efficiency, energy saving and environmental protection requirements, Q4 is expected to start mass production. This fluorescent lamp COB uses four core patented technology industrial packaging group R & D center of independent research and development.

(1) high reflectivity coatings developed by; special coating, 4.5% higher than the traditional silver surface reflectivity, thereby greatly improve the optical efficiency of COB.

(2) independent reflection cup

The traditional COB package most of the whole reflection cup, because the current use of plane structure chip, the chip side light in about 20% of the whole chip side light reflection cup, mutual absorption, light efficiency of the whole COB.

The design uses an independent reflective cup, to avoid the side light absorption between chips. (3) the use of all metal reflector

At present, most of the LED packaging structure is made of PPA and metal copper sheet, because the reflectivity of silver plating on metal is more than PPA, so it can improve the light efficiency of LED by the whole metal reflector cup. (4) the independent research and development of silicone modified silica gel technology is the refractive index of around 1.53 in general, industrial packaging research center by adding nano materials in silica gel, silica gel to improve the refractive index, so as to improve the optical efficiency of COB. The fluorescent lamp (1): COB has the advantages of high light efficiency, light efficiency exceeded 160lm/W

The fluorescent lamp COB uses four patented technology R & D center of independent research and development of pharmaceutical packaging, the COB light efficiency exceeded 160lm/W. The following is the analysis of 1.2m fluorescent lamp.

The use of fluorescent tube COB production of fluorescent lamp, the lighting effect can be increased by 35%.
