Description
Technical field
The utility model relates to a kind of LED illumination optics field, especially a kind of Novel LED lamp reflector.
Background technology
LED is as the new type light source of new generation of green environmental protection and energy saving; Adopted by all kinds of illuminations place more and more; The light that sends from the LED particle is the distribution of half space lambert type more, in order to reach all kinds of lighting demands, must carry out secondary light-distribution to these light and handle; In the process that luminous intensity distribution is handled, must reduce various types of light energy losses.Existing LED secondary light-distribution device is PC lens, PMMA lens or Electroplating Aluminum reflector etc. normally, and the lens luminous intensity distribution is easy to generate chromatic dispersion and causes colour temperature inhomogeneous, and the reflector reflection efficiency of electroplating aluminum is low; Be prone to aging; Aluminium film easy conductive, the dazzle of this reflector of aluminizing simultaneously is high, and the aluminium film is big to the reflectivity difference of different wave length visible light; Cause the light of LED to depart to some extent through aluminium film reflection back light source color temperature, colour rendering also decreases.
The utility model content
The utility model technical problem to be solved is to provide a kind of Novel LED lamp reflector.The utility model can increase substantially the light extraction efficiency of LED light fixture, improves the street lamp color temperature uniformity, guarantees that LED street lamp colour rendering is consistent with the led light source colour rendering, and solves LED street lamp spot glare problem.
For solving the problems of the technologies described above, the technical scheme of the utility model is following: a kind of Novel LED lamp reflector is characterized in that: comprise the reflection cup, the bottom of reflection cup is provided with LED lamp pearl, and the inner surface of reflection cup is provided with reflective membrane.
In the aforesaid Novel LED lamp reflector, described reflective membrane is greater than 97% reflectance coating to the reflectivity of all band visible light.
In the aforesaid Novel LED lamp reflector, described reflective membrane is expanded polytetrafluoroethylsealing (e-PTFE) reflective membrane.
In the aforesaid Novel LED lamp reflector, the inner surface of described reflection cup is parabola, sphere or the conical surface.
The beneficial effect of the utility model: compared with prior art; The utility model applies one deck reflective membrane (like expanded polytetrafluoroethylsealing (e-PTFE) reflective membrane) through going up at the inner surface (being reflecting surface) of reflection cup; Reflective membrane has full wave superelevation reflection characteristic of visible light and good even light characteristics; Can promote the utilization rate that the LED particle emits beam, make the energy-saving effect of LED light fixture more obvious, reduce owing to the loss of secondary light-distribution to LED light; Secondly, the full spectrum ultra-high reflectivity in the visible-range can guarantee that the high-color rendering of LED light fixture can be unaffected, and light is soft, does not have the dazzle of local Gao Liang; Also the technology than traditional aluminum plating process production reflector is simple, is prone to processing, and is with low cost, easy industrialized production; Adopt the LED light fixture reflector high-temp resisting high-humidity resisting of this reflectorized material, and reflectivity decays in time slowly, can increase the service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Being labeled as in the accompanying drawing: the 1-reflective membrane, 2-reflects cup, 3-LED lamp pearl.
Below in conjunction with the specific embodiment the utility model is further described; The embodiment of the utility model is not limited to following embodiment, all belongs within the protection domain of the utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
The specific embodiment
Embodiment.A kind of Novel LED lamp reflector is characterized in that: comprise reflection cup 2, the bottom of reflection cup 2 is provided with LED lamp pearl 3, and the inner surface of reflection cup 2 is provided with reflective membrane 1.The inner surface of described reflection cup 2 is reflectings surface.
Reasonablely be that described reflective membrane 1 is greater than 97% reflectance coating to the reflectivity of all band visible light.
Be more preferably, described reflective membrane 1 adopts the expanded polytetrafluoroethylsealing reflective membrane.
The inner surface of described reflection cup 2 (being reflecting surface) can be parabola, sphere or the conical surface.
The utility model applies one deck reflective membrane (like expanded polytetrafluoroethylsealing (e-PTFE) reflective membrane) through going up at the inner surface (being reflecting surface) of reflection cup; Reflective membrane has full wave superelevation reflection characteristic of visible light and good even light characteristics; Can promote the utilization rate that the LED particle emits beam; Make the energy-saving effect of LED light fixture more obvious, reduce owing to the loss of secondary light-distribution to LED light; Secondly, the full spectrum ultra-high reflectivity in the visible-range can guarantee that the high-color rendering of LED light fixture can be unaffected, and light is soft, does not have the dazzle of local Gao Liang; Also the technology than traditional aluminum plating process production reflector is simple, is prone to processing, and is with low cost, easy industrialized production; Adopt the LED light fixture reflector high-temp resisting high-humidity resisting of this reflectorized material, and reflectivity decays in time slowly, can increase the service life.
The utility model can increase substantially the light extraction efficiency of LED light fixture, improves the street lamp color temperature uniformity, guarantees that LED street lamp colour rendering is consistent with the led light source colour rendering, and solves LED street lamp spot glare problem.
