Description
Technical field
The present invention relates to display field, more particularly to a kind of mixing light source projection light engines system.
Background technology
Minitype projection machine has strict requirements to brightness, resolution ratio, volume, power consumption, cost and radiating etc..Realize
High brightness, high-resolution, small size, low-power consumption and low cost micro projection system, just must light source, optical modulation device,
The many-side such as optical system and optics does very big improvement or even innovation.
Current micro projection is used as lighting source using LED mostly.LED has small volume, long lifespan, response is fast and saves
Can be environmentally friendly the advantages of, but in micro projection using upper, however it remains LED light flux is not high, and the light in unit etendue
The problems such as flux is excessive less than conventional projection light source, and caloric value.For lifting LED luminous efficiencies, phosphor technologies can be used.
The LED of other wavelength is prepared using the high advantage of some wavelength LED luminous efficiencies, to improve the luminous efficiency of the wave band.It is logical
Often, green band LED luminous efficiencies are relatively low, but the proportion that green glow is accounted in projection systems is maximum.Green glow is excited with blue-ray LED
Fluorescent material obtains green glow commercialization, although brightness has been lifted, but there is also deficiency：Spectral region is wide, although main
Wavelength still has portion of energy in green range, but in other wave-length coverages, and fluorescent material excites the halfwidth degree of green light LED
(FWHM) twice of more to 100nm is increased, and common green light LED is only 44nm；Color purity is substantially reduced, and other primary colours scopes
Interior energy can not effectively be utilized by system；Fluorescent material excites LED lighting angle increased so that the optics of light source expands
Exhibition amount increases, and the design to follow-up system brings pressure.
Another emerging light source is laser.Laser is as the optical projection system of light source with very high brightness, without focusing
With the remarkable advantage such as colour gamut broadness, this is all that LED projection system is incomparable.But, there is also be difficult to overcome for laser projection
Shortcoming：Very green laser is not commercialized yet, and cost is too high, and current green laser is mostly based on frequency doubling technology generation；In the presence of safety
Problem；There is image speckle, due to the strong coherence of laser, display image picture is interfered and light and shade graininess is presented,
Visual fatigue is easily produced, sense organ comfort level is substantially reduced.

The many disadvantages of system can not be commercial.Therefore, how to be improved in terms of light source, improve system output brightness, be this area skill
Art personnel technical problem urgently to be resolved hurrily.
