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.
