Embodiment 1
[0029] Dip fritted glass into 1×10 -4 mol / L rhodamine 6G ethanol solution, take out after fully absorbing this solution, dry, obtain porous glass, according to figure 1 The white light emitting diode is prepared by encapsulating in a manner, and the white light emitting diode of the present invention includes a semiconductor light emitting chip 1 , an insulating material 2 , an electrode 3 , a light emitting material 4 , and a lead 5 . In this embodiment, the main emission peak wavelength of the semiconductor light-emitting chip 1 is 468.7 nm, and the light-emitting material 4 is selected from the porous glass containing rhodamine 6G prepared in this embodiment. The porous glass is directly fixed on the semiconductor light-emitting chip with glue to obtain the white light-emitting diode provided by the embodiment of the present invention. The measured optical parameters of the white light emitting diode are shown in Table 1. The light efficiency is 55.07lm / W, the color coordi...
Embodiment 2
[0033] Dip the fritted glass into a 5×10 -5 mol / L rhodamine 6G ethanol solution, after fully absorbing the solution, take out and dry to obtain porous glass. The manufacturing method of the white light emitting diode of the present embodiment is the same as that of embodiment 1. The optical parameters of this white light emitting diode are shown in Table 1. Its luminous efficacy is 58.67lm / W, its color coordinates are (0.4138, 0.3619), and its color temperature is 3054K. Part of the blue light emitted by the blue chip excites the porous glass containing rhodamine 6G, causing the porous glass to emit yellow-red light, and the yellow-red light is combined with the remaining blue light emitted by the blue chip to form white light.
Embodiment 3
[0035] Dip the fritted glass into a 2×10 -5 mol / L rhodamine 6G ethanol solution, after fully absorbing the solution, take out and dry to obtain porous glass. The manufacturing method of the white light emitting diode of the present embodiment is the same as that of embodiment 1. The optical parameters of this white light-emitting diode are shown in Table 1. Its luminous efficacy is 55.77lm / W, its color coordinates are (0.3834, 0.3334), and its color temperature is 3515K. Part of the blue light emitted by the blue chip excites the porous glass containing rhodamine 6G, causing the porous glass to emit yellow-red light, and the yellow-red light is combined with the remaining blue light emitted by the blue chip to form white light.
