Component 24, light focusing unit include an optical mixing cover 25 for being provide with luminescence component 24 and be located at 25 peripheral side of optical mixing cover for reducing
The concentrating component of the divergence of beam angle of luminescence component 24.
Luminescence component 24 is the combination of red LED lamp 241, green light LED lamp 242 and blue LED lamp 243, and concentrating component is
The combination of prefocus cup 26 and collector lens 27.
Red LED lamp 241, green light LED lamp 242 and the distribution setting of 243 triangular shape of blue LED lamp, prefocus cup 26 cover
If the peripheral side of optical mixing cover 25, collector lens 27 is arranged at the light-emitting window of prefocus cup 26.
This second preferred embodiment uses three-color light source, can produce diversified color output, is adopted with three-color LED light
It is calculated with color-sequential method, the characteristic persisted using human vision is achieved the effect that full-color.And then improve the color of display.
The effect of optical mixing cover 25 is uniformly to be mixed tricolor light, and then obtains uniformly mixed white light.Its
The surface of middle optical mixing cover 25 is provided with the micro-structure for being largely used to light mixing.
The structure of the collector lens of the structure and first preferred embodiment of collector lens 27 in this second preferred embodiment
Unanimously.
The course of work of this second preferred embodiment is:
It is penetrated after optical mixing cover 25 is mixed firstly, the light source (luminous component 24) in light source assembly issues tricolor light
Uniform white light out, light carry out first time optically focused by prefocus cup 26, reduce the dispersion angle of light, then pass through the
The light of optically focused carries out second of optically focused by collector lens 27, further reduces the launch angle of light；
Then, a part to emit beam from light source assembly directly radiation direction double-sided prism diffuser plate 22, light source assembly hair
Another part radiation direction Reflecting backboard 21 of light out, laggard 21 diffusing reflection of Reflecting backboard processing, the diffusion of radiation direction double-sided prism
Plate 22；
Finally, the light of radiation direction double-sided prism diffuser plate 22 passes through the scattering process of double-sided prism diffuser plate 22, formed
Area source and out light.
The course of work of this second preferred embodiment is just completed in this way.
