Description
Technical field
The utility model is related to a kind of reflector, especially a kind of reflecting cup structure of uniform in light emission.
Background technology
Reflector has the function of to gather light, and many illuminators can install reflector around light source, allows irradiation light
Intensity be enhanced, and since irradiation light is gathered by reflector, the environment temperature around light source can be caused in the short time
Interior rapid rising, the abnormal heat resistance for testing light source, if temperature is excessively high, or even influences the service life of light source, if in addition, reflector is deposited
In quality problems, it will cause the cup body of reflector to deform, cause the hot spot of irradiation light uneven, not only influence is lighted
Aesthetic effect, visually can be due to emitting brightness be excessive by health hazards under this kind of lamp lighting environment, and generates dazzle
Phenomenon.
Invention content
For overcome the deficiencies in the prior art, the utility model provides a kind of uniform in light emission simple in structure, thermal diffusivity is strong
Reflecting cup structure.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of reflecting cup structure of uniform in light emission, including radiating piece and the reflecting cover above the radiating piece, institute
It states radiating piece to include hollow body and the radiating fin in the hollow body outer wall is arranged, the bottom surface of the reflecting cover is reflective recessed
Face, light-emitting surface is provided at the top of the hollow body, and the light-emitting surface forms angle with horizontal plane, is equipped on the light-emitting surface
Light emitting source.
The number of degrees that the light-emitting surface forms angle with horizontal plane are 45 °.
The inner wall of the hollow body is provided with convex refractive surface, and the convex of several energy refracted lights is provided in the convex refractive surface
Point.
The hollow body is provided with connection through-hole, and the conducting wire for connecting the light emitting source is equipped in the connection through-hole.
The top surface of the reflecting cover is coated with thermal dispersant coatings.
The reflecting cover and the hollow body are coaxial, and the bottom end of the reflecting cover is bonded in the hollow body by fluid sealant
Top surface.
The utility model has the beneficial effects that：The utility model includes radiating piece and reflective above radiating piece
Lid, radiating piece include hollow body and the radiating fin in hollow body outer wall are arranged, and the bottom surface of reflecting cover is reflecting concave, hollow body
Top be provided with light-emitting surface, light-emitting surface forms angle with horizontal plane, is equipped with light emitting source on light-emitting surface, radiating piece can be greatly
Heat caused by light emitting source is taken away, the working life of light emitting source, the light directive reflecting cover that light emitting source distributes, reflecting cover are extended
Reflecting concave light is reflexed into convex refractive surface, light is carried out multidirectional refraction again, promotes reflector by convex refractive surface
Light extraction efficiency simultaneously projects reflector with capable of allowing uniform light, solves the problems, such as the dazzle of lamps and lanterns and dazzling.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the sectional view of the utility model；
Fig. 2 is the vertical view of radiating piece.
Specific implementation mode
Referring to Figures 1 and 2, a kind of reflecting cup structure of uniform in light emission, including radiating piece 1 and be mounted on the radiating piece 1
The reflecting cover 2 of top, the radiating piece 1 includes hollow body 3 and the radiating fin 4 in 3 outer wall of the hollow body is arranged, described anti-
The bottom surface of light lid 2 is reflecting concave, and the top of the hollow body 3 is provided with light-emitting surface 5, and the light-emitting surface 5 is formed with horizontal plane
The number of degrees of angle, angle are 45 °, and light emitting source 6 is equipped on the light-emitting surface 5.
The inner wall of the hollow body 3 is provided with convex refractive surface 7, and several energy refracted lights are provided in the convex refractive surface 7
Salient point, improve the light extraction efficiency of reflector.The hollow body 3 is provided with connection through-hole 8, is equipped in the connection through-hole 8
Connect the conducting wire of the light emitting source 6.The top surface of the reflecting cover 2 is coated with thermal dispersant coatings, enhances the thermal diffusivity of reflecting cover 2, prevents
Reflecting cover 2 is deformed because of high temperature.The reflecting cover 2 and the hollow body 3 are coaxial, and the bottom end of the reflecting cover 2 passes through fluid sealant
It is bonded in the top surface of the hollow body 3.
Radiating piece 1 can greatly take away heat caused by light emitting source 6, extend the working life of light emitting source 6, in reflector
When work, for the light that light emitting source 6 distributes with 45 ° of degree angle directive reflecting covers 2, light is reflexed to folding by the reflecting concave of reflecting cover 2
Convex surface 7 is penetrated, light is carried out multidirectional refraction by convex refractive surface 7 again, is promoted the light extraction efficiency of reflector and can be allowed uniform light
Ground projects reflector, solves the problems, such as the dazzle of lamps and lanterns and dazzling.
Above embodiment cannot limit the protection domain of the invention, and the personnel of professional skill field are not departing from
In the case of the invention general idea, the impartial modification and variation done still fall within the range that the invention is covered
Within.
