Laser lamp bulb structure

Abstract

The invention discloses a laser lamp bulb structure. The laser lamp bulb structure at least comprises a glass lampshade and a lamp bulb base connected with the glass lampshade; the glass lampshade isa hollow lampshade with mixed fluorescent powder, the hollow lampshade is made of glass, and colors of the mixed fluorescent powder at least comprise red, green and blue; in addition, a driving circuit board is arranged in the lamp bulb base and provided with at least one laser diode used for emitting ultraviolet or near-ultraviolet waves, the laser diodes can be driven by the driving circuit board to emit light rays and can excite the mixed fluorescent powder to emit light when the light rays irradiate the inner wall face of the glass lampshade, the fluorescent powder with different colors emits light simultaneously, and white light can be emitted out after the light is mixed.

Description

technical field [0001] The invention relates to a laser bulb structure, in particular to a laser bulb structure capable of emitting white light. Background technique [0002] At present, the most traditional light bulbs are tungsten filament bulbs, but tungsten filament bulbs have the defects of high heat generation, poor efficiency, low life and waste of energy. Therefore, with the development of science and technology, LED bulbs have begun to appear. LED bulbs are a A light bulb with a light-emitting diode as the light source, and the LED light bulb has a lamp cap with an internal drive circuit board connector type, which is the same as the lamp cap of a traditional tungsten filament bulb, so it can be directly assembled on a traditional lamp socket for use, and has advantages in use. convenience. [0003] But this type of LED bulb still has the following defects: [0004] (1) The general color rendering index of LED bulbs is generally low. [0005] (2) white light spec...

AI Technical Summary

Problems solved by technology

[0004] (1) The general color rendering index of LED bulbs is generally low

[0005] (2) white light spectrum figure 1 As shown, there will be a significant blue peak (peak), this is because the white light of the LED bulb comes from a layer of YAG yellow phosphor coated on the surface of the blue LED chip, and when the blue light hits the YAG phosphor, it will excite YAG Phosphor, but because the blue light must also be mixed with the yellow light excited by the YAG phosphor to form white light at the same time, white light will be produced, but because the blue light needs to be mixed with the yellow light to form a white light in addition to exciting the YAG phosphor White light, therefore, produces figure 1 Blu-ray peak, and the Blu-ray problem is also a concern for current users

[0006] (3) The current LED bulbs use plastic lamp housings, so they are not environmentally friendly
