OSRAM launched its first LED filament lamp

China LED Reuters] recently, the German OSRAM (OSRAM) launched the new Soleriq L 38, is the first of its product line LED filament products. The slender LED filament is similar to the ordinary incandescent filament, but has an absolute advantage.

Soleriq L 38 LED filament length of 30mm (including both ends of the 38mm), the diameter of 1.8mm, elongated shape and very similar to the traditional tungsten wire. The utility model has the advantages that the luminous angle is 360 degrees, the light quality is high, and the utility model is very suitable for imitating the traditional appearance. Depending on the color, forward voltage and brightness, the Soleriq L 38 LED filament contains a variety of MacAdam elliptical packets. Therefore, it has uniform colors and uniform light.

OSRAM semiconductor product manager Wong Kum Yih said: "the production of LED filament lamp using the traditional lamp production line is very simple, only need to be changed a little in the manufacturing process, can be fixed to the LED filament lamps, the same with the traditional installation method of filament. That is, a plurality of LED filaments are arranged in parallel according to the forward voltage, so as to ensure stable operation.

Soleriq LED series lamp color uniform, uniform light, very suitable for home, hotel and restaurant lighting. As with the other series of products, Soleriq L 38 provides high brightness, and its luminous flux is divided into 90lm, 130lm, 140lm three. This shows that all 60W and below the traditional lamps can be replaced by equivalent LED filament lamp. The required driving voltage of the LED filament lamp can also be adjusted. Soleriq L 38 LED filament lamp can achieve maximum luminous efficiency of 150lm/W, providing warm white (2500-4000 K), the color index CRI of more than 80, very suitable for indoor lighting, especially Home Furnishing lighting.
