The latest LED die emission efficiency is up to 230lm/W. After the introduction of
LED bulbs , the light efficiency can still be maintained up to 230lm/W, which is not affected by the reduction of light efficiency of the lamps, and the
LED bulbs are illuminated. The angle can reach 300 degrees. Compared with the current half-circumference LED bulb's illumination angle of 120 degrees or the full-circumference light bulb of 270 degrees, the new product will greatly increase the wide-angle performance of the LED bulb.
According to the industry's previously published LED grain luminous efficiency, in the laboratory stage, the US CREE has reached 265lm/W, the Japanese is up to 250lm/W, and the current 230lm/W grain efficiency is The laboratory stage is ranked 3rd in the world. If it is mass-produced, it will be the world's brightest LED die product. The circle does not specify its technical principles, but it is understood that the product is applied to small-sized LED dies by phosphor coating technology.
According to Yuyuan, due to the improvement of efficiency, the chips used in LED bulbs can be greatly reduced, the efficiency and heat dissipation requirements are also greatly reduced, and the manufacturing cost naturally decreases. It is expected to be mass-produced in November and will be available every month in the future. Into the revenue contribution of 50 million yuan.
