Embodiment 1
[0025] Such as figure 1 , figure 2 and image 3 Commonly shown, a white light LED, this white light LED is a SMD5630 lamp tube, including a bracket 1, the upper part of the bracket 1 is provided with a heat dissipation cup 11, the bottom of the heat dissipation cup 11 is provided with 10 and electrodes 6, and the copper block 10 is provided with a heat dissipation cup At the center of the bottom of 11, a blue light chip 2 is provided on the copper block 10, and a wire 7 is connected between the blue light chip 2 and the electrode 6. The wire 7 is a gold wire, and the inside of the cooling cup 11 is coated with fluorescent glue 8, which is Prepared from the following raw materials, TMR-200647-380490 phosphor (Shenzhen Tumeng Electromechanical Technology Co., Ltd.): silicate 05742 phosphor (Intemei Optoelectronics (Shenzhen) Co., Ltd.): silicate, nitride BLT-2500-AB Phosphor powder (Intemei Optoelectronics (Shenzhen) Co., Ltd.): Silica gel 6551AB (Dow Corning 6551 silica gel,...
Embodiment 2
[0037] Such asfigure 1 , figure 2 and image 3 Commonly shown, a white light LED, its structure is basically the same as that of Example 1, the difference is that TMR-200647-380490 fluorescent powder in fluorescent glue 8, silicate 05742 fluorescent powder, silicate, nitride BLT-2500 -The weight ratio of AB phosphor and silica gel 6551AB is: TMR-200647-380490 phosphor: silicate 05742 phosphor: silicate, nitride BLT-2500-AB phosphor: silica gel 6551AB=X:Y:Z :100, where X=0.4, Y=2, Z=5.
Embodiment 3
[0039] Such as figure 1 , figure 2 and image 3 Commonly shown, a white light LED, its structure is basically the same as that of Example 1, the difference is that TMR-200647-380490 fluorescent powder in fluorescent glue 8, silicate 05742 fluorescent powder, silicate, nitride BLT-2500 -The weight ratio of AB phosphor and silica gel 6551AB is: TMR-200647-380490 phosphor: silicate 05742 phosphor: silicate, nitride BLT-2500-AB phosphor: silica gel 6551AB=X:Y:Z :100, where X=0.4, Y=5, Z=2.
