Abstract
The invention relates to the laser projection field, and discloses a laser projection light source realization apparatus. The realization apparatus comprises a fluorescent powder color wheel, a laser diode array and a lens array, wherein the laser diode array is provided with multiple laser diodes and laser alignment lenses; the lens array comprises multiple lenses which are corresponding to the laser diodes and the laser alignment lenses; the fluorescent powder color wheel is arranged on the other side of the lens array; and the fluorescent powder color wheel is provided with a fluorescent powder region and a non-fluorescent-powder region. By adoption of the abovementioned technical field, the high-efficiency laser projection light source realization apparatus is manufactured. Multiple beams of laser can illuminate the different regions of the fluorescent powder color wheel, so that the power of single-point fluorescent powder is reduced; and therefore, the temperature of the single-point fluorescent powder is greatly lowered, thereby improving the excitation efficiency and facilitating realization of a brighter projection system.
Description
Technical field
The present invention relates to laser projection field, more particularly to a kind of laser projection light source realizes device.
Background technology
As blue laser develops comparative maturity, therefore laser projection major part adds fluorescent material using blue laser now
Technology blue laser be irradiated on the fluorescent material of different colours the mode of the light for inspiring other colors to obtain colourama
Source.
Because blue laser power limited, in order to realize certain projection brightness output, generally can separate unit machine
Device can be realized using the mode of many blue laser diodes.As shown in Figure 1 and Figure 2, in use by many blue lasers
The blue laser of output converges to a bit on fluorescent powder color wheel 1, then collects the light ejected from the point.But because
Conversion efficiency for fluorescent material is influenced by temperature very greatly, and temperature more high conversion efficiency is lower.Therefore should in the case of high power
The temperature of point will be especially high, very big using difficulty.
Therefore urgent need one kind carries efficient laser projection light source and realizes device.
The content of the invention
In order to solve the above problems, present invention offer one kind carries efficient laser projection light source and realizes device.
A kind of laser projection light source in the present invention realizes device, including fluorescent powder color wheel, diode laser matrix and thoroughly
Lens array, the diode laser matrix are provided with multiple laser diodes and laser collimator lens, and the lens arra includes many
Individual lens corresponding with laser diode and laser collimator lens, the opposite side of the lens arra are provided with fluorescent powder color wheel, institute
State fluorescent powder color wheel and be provided with phosphor area and non-fluorescence powder region.
According to claim 1, laser projection light source realizes a kind of method of device, and multiple laser passes through laser respectively
After diode and lens, the different phosphor area imagings on fluorescent powder color wheel are projected.
The advantages of the present invention are：The present invention provides one kind and carries efficient laser projection light source realization dress
Put.Multiple laser is allowed to be respectively radiated to the zones of different of fluorescent powder color wheel, so as to reduce the power on single-point fluorescent material so that
The temperature of single-point fluorescent material is substantially reduced, and so as to improve launching efficiency, is conducive to the realization of more highlighted optical projection system.
