Embodiment 1

[0043] Such as figure 1 As shown, a high color rendering index laser white light device according to the present invention includes a light source emitting device 1 and a light conversion medium 2, the light conversion medium 2 is fixed on the surface of the light source exit end of the light source emitting device 1, and the light source emits The device 1 includes a blue laser emitting device 11 and a red light source emitting device 12 . The light source emitted by the red light source emitting device 12 is a laser light source or an LED light source. The output wavelength of the light source emitted by the red light source emitting device 12 is 620-750nm. The output wavelength of the blue laser emitted by the blue laser emitting device 11 is 420-470nm. The emission wavelength range of the light conversion medium 2 is 520-620nm, and the transmittance of visible light is ≥85%. The light conversion medium 2 is yellow glass, yellow ceramic or yellow single crystal material....

Embodiment 2

[0046] Such as figure 2 As shown, the difference between this embodiment and embodiment 1 is:

[0047] The blue laser emitting device 11 and the red light source emitting device 12 can be turned on or off at the same time.

[0048] The light source emitting device 1 further includes a green light source emitting device 13 . The output wavelength of the light source emitted by the green light source emitting device 13 is 495-570 nm. The blue laser emitting device, the red light source emitting device and the green light source emitting device can be turned on or off simultaneously.

[0049] The implementation method of the high color rendering index laser white light device is that the blue laser emitting device 11, the red light source emitting device 12 and the green light source emitting device 13 are simultaneously connected by their respective light source outlet a111, light source outlet b121 and The light source output end c131 emits blue laser light, red light sourc...

Embodiment 3

[0051] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the blue-ray laser emitting device 11 is an in-line blue-ray laser emitting device, and the light source output end a111 is located on the upper surface of the in-line blue-ray laser emitting device. The lower surface of the blue laser emitting device is provided with a pin a112. The red light source emitting device 12 is an in-line red light source emitting device, the light source output end b121 is located on the upper surface of the in-line red light source emitting device, and the lower surface of the in-line red light source emitting device is provided with pins b122.

Abstract

The invention relates to a high color rendering index laser white light device comprising a light source transmitting device and a light conversion medium. The light conversion medium is fixed on thelight source emergent end surface of the light source transmitting device. The light source transmitting device comprises a blue light laser transmitting device and a red light source transmitting device. According to the high color rendering index laser white light device and the implementation method thereof, the problems that high color rendering index of the present laser white light device isdifficult to implement and use is limited can be overcome so as to have the advantages of high color rendering index, convenient preparation and low cost.

Description

technical field [0001] The invention relates to a high color rendering index laser white light device and a realization method thereof, which are applied in the lighting field. Background technique [0002] Existing laser white light devices mostly use blue light laser to excite a single-color substance, and it is difficult to achieve a high color rendering index (generally, the color rendering index is below 75), and it is difficult to enter the home or be used by commercial lighting. However, if the method of mixing red-emitting or red-and-green materials in the excited material is difficult to prepare, the cost is high, and it is temporarily difficult to realize. At the same time, the cost of RGB laser emitting white light is extremely high. Therefore, it has become an urgent task to provide a high color rendering index laser white light device capable of achieving high color rendering index, which is easy to prepare and low in cost and its realization method.
