As shown in Figure 1, 2, the laser light source, including:Lasing light emitter (1), the first concentration module, the first diffusion sheet (4), first
Focus module, light splitting switch element (5), the second focus module, diffusion unit and optical wand (11).
Lasing light emitter (1), for providing blue laser.
First concentration module for the laser that lasing light emitter (1) emits to be collimated and compressed, and projects the first diffusion
On piece (4).In the present embodiment, the first concentration module includes collimation lens (2) and compression eyeglass (3), is respectively used to collimated ray
And compression context.
First diffusion sheet (4) for eliminating laser speckle, while making the hot spot reached on fluorescent powder wheel (8) uniform, glimmering
Light stimulates the efficiency is high.
First focus module, for being converged to laser of the reception from the first diffusion sheet (4) and projecting fluorescent powder
It takes turns (8), while the fluorescence being excited on fluorescent powder wheel (8) is carried out receiving light and convergence and projects the second focus module.This reality
It applies in example, the first focus module is made of the first focusing lens (6) and the second focusing lens (7), and an eyeglass can also be used.
As shown in fig. 7, fluorescent powder wheel (8) comprising two regions, the first phosphor area (8a) are green emitting phosphor area
Domain, the second phosphor area (8b) are yellow fluorescent powder region;
It is divided switch element (5), reflection blue laser transmits other color of light;It is divided there are two types of switch element (5) tools
State, respectively state one and state two.The light splitting switch element (5) can be selected as rotatable and energy in the present embodiment
The dichroscope of at least two angles is navigated to, the dichroscope reflection blue laser transmits other color of light.Described two to
In at least two angles that Look mirror is positioned, one of angle corresponds to the state one, another angle corresponds to the state
Two.
For the moment, the dichroscope arrives the laser reflection for excitated fluorescent powder from the first diffusion sheet (4) to state
Second focus module, laser irradiate fluorescent powder wheel (8), the fluorescent powder on fluorescent powder wheel (8) after the focusing of the second focus module
Region inspires the fluorescence of corresponding color, and fluorescence, which is focused by the second focus module and penetrates the dichroscope, projects second
Focus module, the fluorescence after the focusing of the second focus module is using corresponding color on the second diffusion sheet or colour filter colour wheel (10)
Optical filter, white glass region or hollow out, finally project optical wand (11).
When state two, light splitting switch element (5) will come from the laser reflection of the first diffusion sheet (4) to the second focus module,
Laser after the focusing of the second focus module, it is anti-reflection using corresponding color is coated on the second diffusion sheet or colour filter colour wheel (10)
The diffusion sheet of film is irradiated to optical wand (11).

Focus module is tertiary focusing eyeglass (9).
Diffusion unit, shown diffusion unit are colour filter colour wheel (10) either upper and lower directions or multiple directions vibration or rotation
The second diffusion sheet.
Second diffusion sheet is used for the speckle except laser, while through the fluorescence of other colors, is applied to color requirement
The case where not high occasion or lasing light emitter (1) need not filter when providing red, three color laser light source of green and blue.It is main
It to realize and the dynamic of speckle is eliminated by allowing the second diffusion sheet by rotating or vibrating.First diffusion sheet 4 is stationary
, it is limited to eliminate speckle effect.
As shown in Figure 10, the colour filter colour wheel (10), it may include three regions, first area (10a) are set as red filter
Mating plate, second area (10b) are set as green color filter, white glass or hollow out;Third region (10c) is set as diffusion section
The diffusion sheet in domain, the region is coated with through blue light and reflects the anti-reflection film of other color of light.
As shown in figure 11, it is preferred that in order to promote brightness, need to export yellow light, the colour filter colour wheel (10) further includes the
Four regions (10d), the fourth region (10d) is set as white glass or hollow out, for passing through yellow fluorescence.
Since the wave-length coverage of laser is smaller, which still can transmit other waves in visible-range to mirror
Long light.In actual use, if using redgreenblue merely, although the good whole luminous flux of color is low.And it is being added
After yellow light, then white screen luminous flux can be significantly promoted.It is preferred, therefore, that still obtaining wide range high-energy using yellow fluorescent powder
Yellow light simultaneously exports yellow light.
