Description
Technical field
The invention belongs to laser technology field, and in particular to a kind of light source of laser excitation white light.
Background technology
In the prior art, LED, which has substituted electricity-saving lamp, turns into forth generation illuminating product, but due to LED faults in material, takes light
Efficiency nearly reaches limiting value, and laser (LD) is as a kind of new light source, and light efficiency is far above LED, and with technology should
With light efficiency will be lifted further, and fractional energy savings is at least higher by more than 50% than LED.
The content of the invention
The technical problems to be solved by the invention are that notable light can be lifted for monochromatic LD is excited by providing one kind
The lighting source to be emitted white light based on RGB laser of the colour rendering index in source.
The present invention is realized using following technical proposals：
A kind of lighting source to be emitted white light based on RGB laser, including heat abstractor and the laser that is fixed on heat abstractor
Light source, it is characterised in that：The LASER Light Source includes R, G, B three-color light source, and the light source of each color is at least by one or more
It is arranged on heat abstractor, in addition to an optical fiber, the head end point of the optical fiber have multiple ports, the tail end of the optical fiber component is
One normal port, each port of optical fiber head end connect each LASER Light Source, the light that each LASER Light Source is sent are drawn respectively
Make three-color light source in optical fiber after inside of optical fibre mixes and closes beam, directly exported by the port of optical fiber tail-end mixed white
Light.
The above-mentioned lighting source to be emitted white light based on RGB laser, can be applied in following fields：
A kind of light fixture, including the lighting source to be emitted white light based on RGB laser is as light source.
A kind of projection arrangement, including the lighting source to be emitted white light based on RGB laser is as light source.
A kind of flashlight, including the lighting source to be emitted white light based on RGB laser is as light source.
Advantages of the present invention is as follows：
The structure for the special fiber component that the present invention uses, coordinate the design of R, G, B three-color light source, swash relative to monochromatic LD
For hair, the hybrid energy of RGB modes greatly promotes the colour rendering index of light source, has higher economic benefit as light source, can be with
Apply the lighting field in the various white light sources for needing high-color rendering.

On, the lighting source to be emitted white light based on RGB laser also includes an optical fiber 3, and the head end point of the optical fiber has multiple ports, institute
The tail end for stating optical fiber component is a normal port, and each port of optical fiber head end connects each LASER Light Source respectively, will be each
The light that LASER Light Source is sent, which is led in optical fiber, makes three-color light source after inside of optical fibre mixes and closes beam, passes through the port of optical fiber tail-end
Directly export mixed white light.
The structure for the special fiber component that the present invention uses, coordinate the design of R, G, B three-color light source, swash relative to monochromatic LD
For hair, the hybrid energy of RGB modes greatly promotes the colour rendering index of light source, has higher economic benefit.Meanwhile the present invention is also
The lighting source to be emitted white light based on RGB laser described in above-described embodiment can be applied the white light in various high-color renderings
The fields such as light source, flashlight, car light, illuminator or projection arrangement, use as its light emitting light source portion, can equally take
Higher light conversion efficiency is obtained, and is easily assembled in its Stability Analysis of Structures, is advantageous to industrialized production, than the life-span of other light sources
It is higher, greatly save cost.
