Dongshen Electric has listed the LED lighting "Yimeo" that can be replaced with a 40W straight tube fluorescent lamp. It can be applied to the lamps of current 40W straight tube fluorescent lamps without special order. The heat dissipation is improved by exposing the aluminum heat sink to a portion of the tube.
Dongshen Electric has listed the LED lighting "Yimeo" that can be replaced with a 40W straight tube fluorescent lamp. It can be applied to the lamps of current 40W straight tube fluorescent lamps without special order. The heat dissipation is improved by exposing the aluminum heat sink to a portion of the tube. By miniaturizing the bottom plate on which the LEDs are mounted, the range of the shadow of the bottom plate is reduced, and the area where the light reaches is enlarged. The direct illumination at a height of 1 m is 370 lx (when the illumination tube casing is transparent). The illuminance is "the same as a 40W straight tube fluorescent lamp" (the company). Imagine use in tunnels, parking, subways, factories, shops, and street lights.
A total of 120 blue LED chips produced in Japan were used. The three blue LED chips are arranged in a group, and the red and green phosphors are used together to obtain white light. Thus, the average color rendering index (Ra) is higher, reaching 92. Dongshen Electric said that the Ra of the conventional fluorescent lamp type LED lighting tube is about 70, and the Ra of the fluorescent lamp is generally about 84 to 88.
The LED lighting tube adopts a structure based on the lamp ballast. When the fluorescent lamp is replaced, it is not necessary to remove the ballast from the lamp. The lighting mode supports the glow start mode and the quick start mode. The power consumption varies depending on the fixture used, ranging from 20 to 24W. The rated life is 40,000 hours, which is about 5 times that of "common fluorescent lamps" (the company).
Dongshen Electric's LED lighting tube "Mei Ying" exposes aluminum heat sinks in some of the tubes to improve heat dissipation. By miniaturizing the LED-based backplane, the range of the back surface of the backplane is reduced, and the reach of light is expanded.
The outer casing of the pipe body is made of polycarbonate. The housing is available in a creamy and transparent version. The weight is 500g. The suggested retail price is 28,000 yen per trip. Delivery began in late February 2009. It will be sold in boxes, with a box for every 5 baht, and the network direct sales scheduled to start in March 2009 will be sold at 1 。. Strive to sell 50,000 baht in the first year.
