Abstract
The utility model provides a law enforcement appearance, including the law enforcement appearance body, be equipped with the laser hole on the law enforcement appearance body, there is laser lamp pearl, its characterized in that in the laser hole: an outer lens is matched with a hole opening of the laser hole, the outer side surface of the outer lens is a matte surface, and the inner side surface of the outer lens is a matte surface; and the outer lens is also provided with a circular transparent area corresponding to the laser lamp beads, and the diameter of the circular transparent area is smaller than the aperture of the laser lamp beads. Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model provides a law enforcement appearance is provided with outer lens in the place ahead in laser hole, and the reflection condition of light can effectively be eliminated to the mute face and the matte of outer lens, and circular transparent area on the outer lens is less than laser lamp pearl size, can effectively reduce the reflection effect of lamp socket department transparent lens to light, and the laser lamp in the law enforcement appearance can avoid appearing the problem of miscellaneous light, astigmatism and multiple spot when launching the laser like this.
Description
Technical Field
The utility model relates to a law enforcement appearance equipment field, especially a law enforcement appearance.
Background
Along with the popularization of intelligent hardware, market competition is becoming more and more popular, and under the market environment of the superior and the inferior, the product is that practicality and differentiation demand receive market favor more and more. In order to highlight the practicability of the law enforcement instrument for police, most products are added with the function of a laser lamp. Because of the limitation of the existing process and production conditions, the effect of the laser lamp is influenced by the reflection and refraction of the lens and the deviation of the light emitting angle of the lamp bead inside the laser lamp, and the distance deviation between the lamp socket of the laser lamp and the outer lens, the problems of large batch laser stray light, astigmatism and multiple points occur.
SUMMERY OF THE UTILITY MODEL
To the problem, the utility model provides a law enforcement appearance, the laser lamp in the law enforcement appearance avoids appearing the problem of miscellaneous light, astigmatism and multiple spot when the transmission laser.
The utility model adopts the technical proposal that:
the utility model provides a law enforcement appearance, includes the law enforcement appearance body, is equipped with the laser hole on the law enforcement appearance body, and the laser is downthehole to have laser lamp pearl, its characterized in that: an outer lens is matched with a hole opening of the laser hole, the outer side surface of the outer lens is a matte surface, and the inner side surface of the outer lens is a matte surface; and the outer lens is also provided with a circular transparent area corresponding to the laser lamp beads, and the diameter of the circular transparent area is smaller than the aperture of the laser lamp beads.
Preferably, the outer lens is made of polycarbonate.
Preferably, the thickness of the outer lens is 0.2-0.3 mm.
More preferably, the diameter of the laser lamp bead is 2mm, and the aperture of the circular transparent area is 1.5 mm.
Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model provides a law enforcement appearance is provided with outer lens in the place ahead in laser hole, and the reflection condition of light can effectively be eliminated to the mute face and the matte of outer lens, and circular transparent area on the outer lens is less than laser lamp pearl size, can effectively reduce the reflection effect of lamp socket department transparent lens to light, and the laser lamp in the law enforcement appearance can avoid appearing the problem of miscellaneous light, astigmatism and multiple spot when launching the laser like this.
Drawings
Fig. 1 is a schematic diagram of a law enforcement instrument provided by the present invention;
fig. 2 is a schematic view of an outer lens in a law enforcement instrument provided by the present invention.
Detailed Description
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 to 2 show a preferred embodiment of a law enforcement instrument according to the present invention. As shown in fig. 1 to 2, the law enforcement instrument comprises a law enforcement instrument body, wherein a laser hole is formed in the law enforcement instrument body, a laser bead is arranged in the laser hole, an outer lens 10 is matched with an opening of the laser hole, the outer side surface of the outer lens is a matte surface 1001, and the inner side surface of the outer lens is a matte surface 1002; still be equipped with the circular transparent area 1303 that corresponds with laser lamp pearl on the outer lens 10, the diameter in circular transparent area 1003 is less than laser lamp pearl aperture, and the reflection condition of light can effectively be eliminated to the mute face and the matte of outer lens, and circular transparent area on the outer lens is less than laser lamp pearl size, can effectively reduce the reflection effect of transparent lens to light of light mouth department, and the laser lamp in the law enforcement appearance can avoid appearing the problem of miscellaneous light, astigmatism and multiple spot when the transmission laser like this.
The light generated by the laser lamp beads 12 passes through the lens, and refraction and reflection effects can be generated according to different materials and thicknesses of the lens; the refractive index is different according to the material and thickness of the lens; the lower the refractive index and the thinner the thickness, the less likely the refractive effect will be produced.
The outer lens of the utility model adopts Polycarbonate (PC); the thickness of the outer lens is 0.2-0.3 mm; the Polycarbonate (PC) material has low cost and excellent performance, and the light transmittance is 75-90%; a refractive index 1.589. The distance between the inner side laser lamp and the lens is different from the distance between the outer side laser lamp and the lens, and the inner side laser lamp and the outer side laser lamp are reflected by the lens for the second time, and the inner side laser lamp and the outer side laser lamp are combined with actual effect verification to form an inner side dummy surface; the outer side has the best matte effect.
To sum up, the technical scheme of the utility model can be fully effectual the above-mentioned utility model purpose of realization, just the utility model discloses a structure and functional principle all obtain abundant verification in the embodiment, can reach anticipated efficiency and purpose, do not deviating from the utility model discloses a under the prerequisite of principle and essence, can make multiple change or modification to the embodiment of utility model. Therefore, the present invention includes all the alternative contents within the scope mentioned in the claims, and all the equivalent changes made within the claims of the present invention are included in the claims of the present application.
