Description

A kind of high power white light beam generated device based on the even light of secondary

Technical field

The utility model belongs to optical technical field, relates to a kind of high power white light beam generated device based on the even light of secondary.

Background technology

Existing high power white light mainly white light LEDs, its generation method mainly contains: 1, red, green and blue LED integrated chip obtains white light by three primary colours synthetic method on same substrate, the method cost is high, and the different synthesis light spectrum that causes of three kinds of color LED rate of decay is in time uneven; 2, white light is formed by the proportioning of the near ultraviolet LED red, green, blue fluorescent powder of adjustment high brightness, the method is almost similar with three primary colours synthesis, but power-type ultraviolet LED is not easy to make efficiently, excite low-energy RGB light from causing efficiency lower, and there is the potential safety hazard that ultraviolet is revealed in encapsulating material easy aging life-span decay under the irradiation of ultraviolet light simultaneously; 3, with power-type GaN base blue-ray LED for the yellow inorganic fluorescent powder of pump excitation or yellow organic fluorescent dye, the gold-tinted of acquisition and original blue light is excited again to produce the white light of vision, but this method due to blue-ray LED luminescence efficiency not high not enough, and the loss of blue-light excited fluorescent powder produce power, fluorescent powder and encapsulating material cause color temperature shift along with the time is aging, and along with the uneven problem of space chromacity; It is non-adjustable all to there is chromatogram in above three kinds of method gained white lights, and spatially uniform is low, damages unrepairable, the shortcoming that light efficiency is low, and the gained light angle of divergence is large, and the bad control of beam shape, need carry out optics luminous intensity distribution.

Utility model content

In view of this, the purpose of this utility model is to provide a kind of high power white light beam generated device based on the even light of secondary, and this device can produce that to have spectrum adjustable, and brightness is high, the high-power low-angle equal white light light beam that light efficiency is high.

For achieving the above object, the utility model provides following technical scheme:

Based on a high power white light beam generated device for the even light of secondary, this device comprises three primary light source, collimation lens, homogenize fly's-eye lens, secondary homogenize fly's-eye lens, integration lens I and an integration lens II; Described three primary light source carries out a homogenize respectively through after collimation lens through once homogenize fly's-eye lens; Then carry out integration focusing through integration lens I, then carry out secondary homogenize through secondary homogenize fly's-eye lens, after eventually passing integration lens II, produce high power white light light beam.

Further, described secondary homogenize fly's-eye lens is positioned over the focal plane of integration lens I.

Further, described three primary light source is RGB laser diode.

Further, described secondary homogenize fly's-eye lens acceptance angle is greater than a homogenize fly's-eye lens acceptance angle.

Tricolor laser light source module quantity can be increased according to required luminous power and realize high brightness, high-power.

The beneficial effects of the utility model are: a kind of high power white light beam generated device based on the even light of secondary that the utility model provides, adopt laser as light source, in conjunction with the advantage that laser beam quality is good, emergent light being had, brightness is high, light efficiency is high, spectrum is adjustable and the advantage that luminous intensity distribution difficulty is low; Secondary homogenize is adopted to carry out shaping homogenize to light beam, both can realize RGB conjunction light and obtain white light, make again outgoing beam beam propagation whole space illumination and uniformity of chromaticity high, and spot size is consistent than with the single lenticule of a homogenize fly's-eye lens; Use fly's-eye lens to complete light beam synthesis homogenize, light source module can be increased as required at light source place, therefore can high power light beam be obtained; Tricolor laser light source module quantity can be increased according to required luminous power and realize high brightness, high-power; This apparatus structure is simple, easily realizes.

Accompanying drawing explanation

In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:

Fig. 1 is the structural representation of device described in the utility model;

Wherein, 1 in Fig. 1 is three look LASER Light Source, and 2 is collimation lens, and 3 is a homogenize fly's-eye lens, and 4 is integration lens I, and 5 is secondary homogenize fly's-eye lens, and 6 is integration lens II.
