Description
Technical Field
The utility model relates to an optical lens technical field, in particular to flash lamp lens.
Background
A flash is a device for providing light when the amount of light is insufficient or when an auxiliary light source is required during photographing. The flash lamp generally includes a light source unit, which may use xenon or a Light Emitting Diode (LED), and a lens unit, which may use plastic or glass. Recently, most small electronic devices may have a small camera embedded therein, which may affect a photographing effect when light is insufficient in photographing a scene, and thus a flash is frequently used. The prior flash lamp has the following defects: 1) the LED lamp can emit light with strong brightness instantly, but the use of the flash light can cause the problems of high local brightness and uneven illumination; 2) the installation is fixed complicated, easily drops.
Disclosure of Invention
An object of the utility model is to provide a flash light lens to prior art not enough, luminous even, the fixed mounting of being convenient for.
In order to achieve the purpose, the utility model discloses a flash lamp lens, including the lens body, the lens body includes lens installation position and lens unit, the lens unit includes income plain noodles, plane of reflection and play plain noodles, the income plain noodles is inside sunken cylindrical cavity, the top of cylindrical cavity is convex, the plane of reflection includes first plane of reflection and second plane of reflection, it is provided with the fresnel ring of big homocentric axis from little to big to go out the plain noodles.
Further, the lens mounting position and the lens unit are integrally connected.
Furthermore, the lens mounting position is provided with four mounting holes.
Further, the reflecting surface is sprayed with white paint.
Further, the second reflecting surface is an inclined surface.
Further, the lens unit is cylindrical.
The utility model has the advantages that:
1) the top end of the light incident surface is arc-shaped, so that light rays can be uniformly dispersed in the lens when entering the lens, and the light uniformity of the lens of the flash lamp is increased.
2) Set up lens installation position, played the effect of the fixed mounting of being convenient for to the lens main part, stability when having increased the installation of lens main part prevents that the appearance from dropping after the installation of lens main part.
3) The reflecting surface can carry out total reflection on incident light of the light incident surface, and the light guide efficiency of the flash lamp is improved.
4) The light emitting surface is provided with Fresnel rings which are concentric with the central axis from small to large, and the light source can be uniformly diffused through the refraction and reflection of light.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a bottom view of the structure of the present invention;
FIG. 3 is a top view of the present invention;
in the figure: the lens comprises a 1-lens unit, a 2-lens mounting position, an 11-light-in surface, a 12-light-out surface, a 13-first reflecting surface, a 14-second reflecting surface and a 21-mounting hole.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3:
the utility model provides a flash lamp lens, includes the lens body, and the lens body includes lens installation position 2 and lens unit 1, and lens installation position 2 and lens unit 1 integrated into one piece are connected. The lens unit comprises a light incident surface 11, a reflecting surface and a light emergent surface 12, wherein the light incident surface 11 is an inwards-recessed cylindrical cavity, the top end of the cylindrical cavity is in a circular arc shape, the reflecting surface comprises a first reflecting surface 13 and a second reflecting surface 14, and the light emergent surface 12 is provided with Fresnel rings which are concentric with a central axis from small to large.
The light incident surface 11 is an inwardly recessed cylindrical cavity for accommodating an LED light source, and the top end of the cylindrical cavity is arc-shaped and can disperse incident light, so that the peripheral illumination of emergent light is increased, the central illumination is reduced, and the uniformity of the emergent light is increased.
Lens installation position 2 can be square, circular, quadrangle, hexagon, and lens installation position 2 is square in this embodiment, is equipped with four mounting holes 21 on the lens installation position 2, has played the fixed mounting's of being convenient for effect to the lens main part, and stability when having increased the installation of lens main part prevents that the appearance from dropping after the installation of lens main part.
The light emitting surface 12 is provided with a Fresnel ring which is concentric with the central axis from small to large, the Fresnel ring is composed of a series of Fresnel saw teeth with the same height, a sawtooth-shaped groove is formed between every two adjacent Fresnel saw teeth, and the angle between each sawtooth-shaped groove and the adjacent sawtooth-shaped groove is the same. The emergent light of the emergent surface 12 is changed through the Fresnel ring, so that the emergent light is distributed in a wider direction and is irradiated more uniformly.
The reflecting surface is sprayed with white paint to form a reflecting layer, the shape of the reflecting surface can be set by using a diffusion principle, wherein the second reflecting surface 14 is an inclined surface, the first reflecting surface 13 is a horizontal surface, and the reflecting surface can carry out total reflection on incident light of the light incident surface 11, so that the light loss rate is reduced, and the light guide efficiency of the flash lamp is increased.
During the use, the LED light source sets up the central point that goes into 11 cylindrical cavities at the plain noodles and puts, and first plane of reflection 13 bonds and seals fixedly at the PCB board of LED light source, can effectually prevent the entering of dust, dust etc to influence the efficiency of flash light.
It should be understood that the above description is only exemplary of the present invention and is not intended to limit the present invention, and that any modifications, equivalents, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
