Embodiment 1

[0039] Such as Figure 1-3 As shown, an in-line laser white light source according to the present invention includes an in-line blue laser emitting device 1, a light conversion medium 2 and a fixing device 3; the upper surface of the in-line blue laser emitting device 1 is a laser The exit end 11 has a pin 12 on the lower surface; the light conversion medium 2 is fixed on the surface of the laser exit end 11 of the in-line blue-ray laser emitting device 1 through the fixing device 3; the in-line blue-ray laser emitting device 1 emits The blue laser light passes through the light conversion medium 2 and is excited and converted into white light.

[0040] The light conversion medium 2 is any one of fluorescent glass, transparent fluorescent ceramics, and fluorescent single crystal. Its body is yellow or yellow-green, and the wavelength of white light converted by it is 520-760nm.

[0041] The visible light transmittance of the light conversion medium 2 is ≥80%.

[0042] The l...

Embodiment 2

[0050] Such as figure 1 , 2 , 4, the difference between it and Embodiment 1 is that the laser emitting end 11 of the in-line blue-ray laser emitting device 1 is embedded in the light conversion medium 2 .

Embodiment 3

[0052] Such as figure 1 , 2 , 5, the difference between it and Embodiment 1 is that: the shape of the light exit surface 21 of the light conversion medium 2 is a conical surface, and the exit angle of the conical surface is 1-150°.

Abstract

The invention relates to a direct insertion type laser white light source. The direct insertion type laser white light source comprises a direct insertion type blue laser emitting device, a light conversion medium and a fixing device, wherein a laser emitting end is formed on the upper surface of the direct insertion type blue laser emitting device, and pins are arranged on the lower surface of the direct insertion type blue laser emitting device; the light conversion medium is fixed to the surface of the laser emitting end of the direct insertion type blue laser emitting device by virtue of the fixing device; and blue laser emitted by the direct insertion type blue laser emitting device is activated and converted into white light through the light conversion medium. The direct insertion type laser white light source has the advantages of simple process, high light emitting efficiency and convenience in application and is favorable for scale production, and the defects of lag in technology, complex process, low efficiency and inconvenience in application because an existing traditional light source emitting component adopts an LED (Light Emitting Diode) or RGB or color chips (colorwheels) are overcome.

Description

technical field [0001] The invention relates to an in-line laser white light source, which is applied in the lighting field. Background technique [0002] At present, the most advanced technology used in the field of lighting is LED lighting. Compared with traditional incandescent lamps and energy-saving lamps, LED lighting can save 50-70% of electricity; and laser lighting, as the next-generation lighting technology of LED, can save 50-50% of electricity compared with LED. 80%, will become the replacement product of LED. Most of the existing light source light-emitting components use LEDs or RGB or color chips (color wheels) in laser lighting, which are backward in technology, complicated in process, low in efficiency and inconvenient in application. Therefore, it has become an urgent task to provide an in-line laser white light source with simple process, high luminous efficiency, stable luminescence, convenient application, and favorable for large-scale production. Con...
