Large light angle LED bulb debut Lighting Fair 2011 LED bulb lineup increasingly rich

In recent years, LED lighting because the price decreased rapidly and the improvement of the brightness and concern. This competition will continue in the future. However, the technical focus of each LED bulb companies seem to have turned to the next stage.

In the "Lighting Fair 2011" (March 2011 8 ~ 11 days, Tokyo Ming International Exhibition Center), various companies have expanded the display light distribution angle of LED light bulb. Moreover, so far only part of the manufacturers engaged in dimming and spherical bulb LED bulb business, the participating manufacturers have begun to increase. In particular, to support the dimming of the product, for the LED to replace the incandescent light bulb market competitors, which is the field of delay has been pushed forward. LED light bulb with the expansion of the light angle, the shape is closer to the incandescent lamp, the product lineup is also beyond the bulb type fluorescent lamp, and gradually become a "common commodity".

In the realization of the expansion of light angle, shape is also similar to the incandescent lamp LED lamp product is one of the first step in the panasonic. The company in January 2011 issued a 300 degree light with an ordinary light bulb (support E26 lamp mouth) LED bulbs, and is scheduled to go on sale in March 18, 2011 (see site reports). The reflection plate is arranged at the same time of the stereo configuration of the LED chip, and the light distribution angle is enlarged. In the light of the larger angle of the LED bulb, the German OSRAM and Rom and other products have been achieved, but in the shape and distribution of light is also difficult to match the incandescent bulb.

Following Panasonic, Toshiba lighting technology in March 7, 2011 released a 260 degree light angle with LED bulbs, and is scheduled to be listed in April 15th. The company is also on display at the show with a 270 degree light angle and 1100lm brightness of the LED bulb. According to the published data, the light distribution angle of 260 degrees with the original LED lighting products, plane configuration LED chip, using only the shade (semicircle cover) the diffusion of light to achieve high photochemical. In addition, at the same time to achieve a 270 degree of light and 1100lm brightness of the development of the product looks like Panasonic's products, three-dimensional configuration of the LED chip. In addition, Toshiba lighting technology is also a reference to the display of the bulb LED bulbs and support ClearType and dimmable Mini krypton bulb (support E17 lamp mouth) LED bulbs, expanded product lineup.

Toshiba displays spherical bulb and mini krypton bulbs

Hitachi Electric's show expanded light distribution angle of LED light bulb. Ordinary light bulb type products with the same angle of Panasonic, also has a light support products. In addition, in the mini krypton lamp type products also showed a larger light distribution products.
