As shown in Figure 1, a kind of laser lamp, including outer cover of lamp holder 10, and be arranged successively be fixed on lamp holder from the inside to the outside Laser 20, optically focused part 30, transflection mirror 40, fluorescent powder 50, substrate 60, optical filter 70 in shell 10 and it is arranged with optical filter Laser can be formed the fluorescence of white by the reflecting component 80 on 70, fluorescent powder 50, and transflection mirror 40 can penetrate laser and can reflect Fluorescence, fluorescent powder 50, which applies, is set to side on substrate 60, and the size of transflection mirror 40 is greater than the size of substrate 60.

The laser lamp of the utility model is arranged by the way that outer cover of lamp holder 10 is arranged, and in outer cover of lamp holder 10 for shining Laser 20, laser 20 issues laser to optically focused part 30, and optically focused part 30 is for gathering laser, and the laser irradiation gathered is simultaneously It focuses on the fluorescent powder 50 being located on substrate 60, laser forms the fluorescence of white at fluorescent powder 50, then passes through transflection mirror 40 At fluorescent reflection to optical filter 70, optical filter 70 can make laser lamp to have by laser filter and through the fluorescence of white Directional strong, brightness height and far firing range characteristic；Simultaneously as the size of transflection mirror 40 is greater than the size of substrate 60, make White fluorescence is obtained when reflexing at transflection mirror 40, all fluorescence in front can reflex to from filter from transflection Jing40Chu And laser lamp is transmitted, and the fluorescence that rear portion is excited is emitted after then passing through reflecting component calibrating direction.In this way, it is ensured that laser The brightness of lamps and lanterns.

Further, as shown in Figure 1, in the present embodiment, laser lamp further includes the light distribution angle for adjusting fluorescence Lens 90, lens 90 is set to the opening of reflecting component 80, and lens 90 is detachably connected with reflecting component 80.By setting Lens 90 is set, so that laser lamp can adjust the light distribution angle of fluorescence, so that the hot spot of outgoing can be adjusted according to user demand Size, and obtain the desired light distribution effect of user, meet different lighting demands.

Further, as shown in Figure 1, in the present embodiment, the optical axis of optically focused part 30, transflection mirror 40 and lens 90 It is located along the same line.By the way that the optical axis of optically focused part 30, transflection mirror 40 and lens 90 is set as being located along the same line, It may make the light distribution effect of laser lamp preferable.

Further, as shown in Figure 1, in the present embodiment, laser lamp further includes the heat dissipation set on 20 bottom of laser Part 11, radiating piece 11 are set to the bottom of outer cover of lamp holder 10.Since laser 20 can generate a large amount of heat in use, setting The radiating piece 11 contacted with laser 20, and the heat derives generated laser 20 by radiating piece 11 are in outside laser lamp, It avoids heat from depositing, and then avoids high heat that laser lamp is caused to damage, the service life of effective guarantee laser lamp.

Further, as shown in Figure 1, in the present embodiment, substrate 60 is transparent high temperature resistant material member.Since laser has Higher ability, and laser 20 project after transflection mirror 40 direct irradiation in be located at substrate 60 fluorescent powder 50 on, Therefore, use high temperature resistant material as the raw material of substrate 60, the use of laser lamp can be met；The route in addition, laser is expert at Meeting off-energy, causes the brightness of fluorescence that can reduce on line, substrate 60 is made by using transparent material, so that substrate 60 will not Stop the path of fluorescence, so that the energy of fluorescence will not be in laser lamp internal loss, in this way, preventing energy from excessively swashing The consumption of light lamp interior, leads to the luminance shortage of the fluorescence projected.It specifically, can be glass-ceramic or quartz glass.

Further, as shown in Figure 1, in the present embodiment, reflecting component 80 is the transmission element with cavity, and reflecting component 80 Inner wall be the curved-surface structure that the wide-angle angle of divergence of fluorescence can be corrected to low-angle.Since LASER Excited Fluorescence powder 50 produces Raw fluorescence does not have directionality, belongs to lambert's body and shines, by the way that reflecting component 80 is arranged, so that fluorescence can be compressed by reflecting component 80 The angle of divergence makes the wide-angle angle of divergence of fluorescence be corrected as the fluorescence of the low-angle angle of divergence, so that fluorescence can be adjusted to that It is similar to directional light and exhales laser lamp.

Further, as shown in Figure 1, in the present embodiment, transflection mirror 40 includes lens and the color separation for covering lens surface Film, dichroic coating is through laser and reflected fluorescent light.By reflection from lens be arranged dichroic coating, laser can transmitted through transflection mirror 40, And the fluorescence of white is gone back when reflexing at dichroic coating by the total reflection of inverse film, and fluorescence is avoided just to be lost in laser lamp, And then ensure the brightness of laser lamp.

Further, as shown in Figure 1, in the present embodiment, the size of optical filter 70 is greater than or equal to the size of opening, and Optical filter 70 covers the opening.By the way that optical filter 70 is sized to the size greater than opening, so that optical filter 70 can seal Opening is covered, so that all light can be by can just be transmitted through outside laser lamp after optical filter 70, only fluorescence can lead to Optical filter 70 is crossed, laser has been avoided directly to be emitted a possibility that causing potential eutrophication.

Further, as shown in Figure 1, in the present embodiment, outer cover of lamp holder 10 is detachably connected with substrate 60, in this way, making Obtaining can conduct the high heat that substrate 60 is subject to outer cover of lamp holder 10, avoid the too fast damage of substrate 60.

The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle Within the scope of shield.
