Description

A kind of full mode of laser group of RGB

Technical field

The utility model relates to full-color field of laser device technology more particularly to a kind of full mode of laser groups of RGB.

Background technique

Full-color laser is widely used in the industry such as biomedicine, laser lighting, projection and civil field, but due to more Long wavelength laser is constantly in the relatively high market environment of price, and there are many urgent problems to be solved, such as R (red laser), G(green laser), B(blue laser) mixing after color uniformity it is bad, uneven illumination is even, and structure size is big, Capacity usage ratio is low, at high cost etc., and these problems directly result in the industry such as biomedicine, laser lighting and civil equipment price It remains high and is difficult to be applied by the field well.

Summary of the invention

(1) technical problems to be solved

The purpose of this utility model is that there are color uniformities is bad for existing full-color laser, and uneven illumination is even, knot The problems such as structure size is big, and capacity usage ratio is low, at high cost, a kind of full mode of laser group of the RGB provided.

(2) technical solution

In order to solve deficiency in the prior art, the utility model provides the full mode of laser group of such a RGB, this is practical It is novel the technical solution adopted is that:

A kind of full mode of laser group of RGB, including red laser light source, green laser light source, blue laser light source, optical-fiber bundling Device, collimation lens, scattering sheet, the optical-fiber bundling device input terminal are connected with 2 or more input optical fibres, and the input optical fibre is Multimode fibre, the optical-fiber bundling device output end are connected with output optical fibre, the red laser light source, the green laser light Source, the blue laser light source are coupled with the input optical fibre by the modes such as welding or pluggable wire jumper interface respectively, The collimation lens is set between the output optical fibre output end and the scattering sheet.

Preferably, the quantity of the red laser light source, the green laser light source and the blue laser light source is distinguished For at least one.

Preferably, the red laser light source, the green laser light source and the blue laser light source can be single respectively Solely control output power.

Preferably, the optical-fiber bundling device passes through the input optical fibre for the red laser light source, the green laser Light source and the blue laser light source laser carry out light combination, the input optical fibre input terminal and output optical fibre output end end face It is coated with AR film respectively.

(3) beneficial effect

The utility model connects 2 or more input optical fibres by setting optical-fiber bundling device, then optical-fiber bundling device input terminal, Optical-fiber bundling device output end connects output optical fibre, and plates AR film respectively in input optical fibre input terminal and output optical fibre output end, Have the function that increase capacity usage ratio and reduce harm of the return light to laser light source, then 2 or more low costs are set low Red laser light source, green laser light source and the blue laser light source of power with replace higher cost high power laser sources, Manufacturing cost is reduced while meeting powerful demand, by individually controlling red laser light source, green laser light The power ratio in source and blue laser light source realizes the output of output end different colours, compares with tradition light combination method, different waves The mixing of long light sufficiently, has good color uniformity and illumination, the benefit designed in this way there are also structures simple, optical fiber transmission, Spatial arrangement is flexible, and size is small, and assembly precision is not high, and low-loss optical-fiber bundling device ensure that capacity usage ratio height, can Up to 90% or more.
