Abstract
The utility model relates to an LED (light-emitting diode) spotlight, which comprises a radiation shell, an arc reflection cup arranged in the radiation shell and an LED sheet light source arranged in the center of the arc reflection cup in the radiation shell, wherein the LED sheet light source arranged in the center of the arc reflection cup is provided with an optical lens which is capable of refracting LED light on the surface of the arc reflection cup. The illumination principle of such an LED spotlight is that the LED sheet light source illuminates outwards through the optical lens, the bottom of the optical lens is concaved into ladder shape for the purpose of refracting the lights emitted from the LED sheet light source onto the outer surface of the optical lens, the light emitted from the LED sheet light source is illuminated on the arc reflection cup through the outer surface of the optical lens, and then the arc reflection cup reflects the lights so as to illuminate. By using the LED spotlight, the illuminator area of the light source is increased, the lighting effect is increased, the illumination is softer, and the exposed LED sheet light source is prevented from directly illuminating into the visual line of people, therefore avoiding uncomfortable cute conjunctivitis of people.
Description
Technical field
The utility model relates to light fixture, especially a kind of LED shot-light.
Background technology
The shot-light of existing led light source is made up of heat-dissipating casing, arc reflector and the LED card sheet laser that is installed in heat-dissipating casing arc reflector center.This LED card sheet laser is directly sticked on the LED shot-light at heat-dissipating casing arc reflector center, though the reflection that LED card sheet laser can be by the arc reflector with light source to external exposure, can increase the brightness of LED card sheet laser.But, the LED shot-light of this structure is owing to the LED card sheet laser that is arranged on heat-dissipating casing arc reflector center is directly outwards to send light, and its light irradiating is and concentrated, and lighting effect is relatively poor, and the LED that exposes card sheet laser can directly be mirrored people's sight line, causes the cute conjunctivitis sense of discomfort to the people.
The utility model content
Technical problem to be solved in the utility model is to remedy the defective that prior art exists, and provide a kind of illumination concentrated and soft, and light source can directly be mirrored the LED shot-light of people's sight line.
The utility model is solved by the following method.
This LED shot-light comprises: heat-dissipating casing, be installed in the arc reflector in the heat-dissipating casing and be arranged on the LED card sheet laser at heat-dissipating casing arc reflector center.
The characteristics of this LED shot-light are:
Described arc reflector center LED card sheet laser is provided with an optics light guiding lens that LED illumination can be refracted to arc reflector surface.
Technical problem of the present utility model is solved by following further technical scheme.
Described optics light guiding lens and LED card sheet laser butt end are provided with the pin that is used for its fixing assembling on heat-dissipating casing.
The bottom face of described optics light guiding lens is provided with
Shape caves in trapezoidal recessed.
It is recessed that the end face of described optics light guiding lens is provided with the taper of caving in of " ∨ " shape.
Described optics light guiding lens is cylindrical body light guiding lens, drum shaped body light guiding lens, step drum shaped body light guiding lens.
Described optics light guiding lens is bullet-headed light guiding lens,
The shape trapezoidal recessed bottom face that is arranged on the optics light guiding lens that caves in.
The beneficial effect that LED shot-light of the present utility model is compared with the prior art is:
This LED shot-light since LED card sheet laser by the optics light guiding lens to external exposure, and optics light guiding lens bottom face
The shape trapezoidal recessed anaclasis that then LED card sheet laser can be sent of caving in is distributed to optics light guiding lens outer surface, and " ∨ " shape of optics light guiding lens end face caves in, and taper is recessed then also anaclasis function, optics light guiding lens two ends
Shape trapezoidal recessed and " ∨ " shape recessed cooperation of taper of caving in of caving in, the illumination that can effectively LED card sheet laser be disperseed is concentrated, by optics light guiding lens outer surface the light of LED card sheet laser is transmitted into the arc reflector again, provides illumination with the reflection of LED card sheet laser by the arc reflector.The illuminator area that it has not only increased light source has improved light efficiency, can make illumination softer, and the LED that can avoid exposing card sheet laser directly mirrors people's sight line, the cute conjunctivitis sense of discomfort that causes to the people.
LED shot-light concrete structure of the present utility model is provided in detail by the following drawings and embodiment.
