Description

A kind of plane LED lamp reflector
Technical field
The utility model belongs to optical design techniques field, and in particular to a kind of plane LED lamp reflector.
Background technology
As forth generation light source and the energy saving light source of 21 century, light emitting diode (Light Emitting Diode, LED) application development is rapid.With the exploitation of its luminous efficiency and great power LED, LED is in commercial lighting field gradual generation For conventional lamp and it is used widely.But LED is point light source, it is necessary to which difference could be met by carrying out necessary secondary optical design The specific optical requirement of lamps and lanterns.
Currently, high-power LED lamp is being increasingly becoming the main product in market.In secondary optical design, lens and Reflector is common two schemes, and due to general LED secondary optical designs, LED light directive front, reflector is controlling There are disadvantage in terms of the luminous flux distribution of LED centers, so transmissive design is more widely applied.Lens compared to transmission-type are set Meter, reflector design have the advantages that uniqueness:The features such as non-dispersive, high luminous flux utilization rate.Also, as great power LED should With increasingly extensively, the flip-over type LED that (shines backward) is eliminated the disadvantage of reflector, and reflector can realize flip-over type LED Central luminous flux distribution.In conjunction with the plurality of advantages of reflector, reflector design has certain application prospect.It is general anti- All using longer reflecting assembly in the design of light cup, not only waste of materials, but also lamps and lanterns volume is made to become larger is unfavorable for LED lamp Heat dissipation etc..Reflector how to be applied to carry out secondary optical design to the great power LED that point light source encapsulates, had both completed the conjunction of luminous flux Reason distribution, while the dispersion of light is avoided to become an important research direction.
Utility model content
The purpose of this utility model is in view of the above-mentioned problems existing in the prior art, it is anti-to provide a kind of plane LED lamp Light cup can realize the utilization rate for improving luminous flux, while can save material, reduce lamps and lanterns volume and avoid the dispersion of light, Greatly improve the quality of lamps and lanterns.
The technical solution of the utility model is as follows:
A kind of plane LED lamp reflector, including LED light source and several plane mirror rings, the reflector by The plane mirror ring of several in one plane annular spreads is formed, and the diameter of plane mirror ring is from outmost turns to most interior Circle is gradually reduced, and ultimately forms a pyramid facial plane, each plane mirror ring and plane are at an angle, two neighboring Plane mirror ring connects at an angle, makes the round reflective plane undulate of reflector.
A kind of plane LED lamp reflector, the plane mirror ring are made of several plane mirrors, each plane Reflective mirror is interconnected amongst one another to form plane mirror ring.
A kind of plane LED lamp reflector, the plane mirror are plane or curved surface, and edge is anti-for place plane The outside of light microscopic ring, the edge of the plane mirror is a fan-shaped or fan-shaped part.
A kind of plane LED lamp reflector, the surface of the plane mirror are coated with reflective material.
A kind of plane LED lamp reflector, the LED light source relative position and plane mirror and reflector plane angle Difference and plane reflector the size difference of degree are, it can be achieved that the distribution of the specified angle of luminous flux and specified magnitude.
The beneficial effects of the utility model are:
The utility model passes through annular spread, compact arranged faceted pebble reflective mirror phase interworking in plane reflector plane It closes, realizes luminous flux reasonable distribution, while optical requirement of the different lamps for light flux distribution is met, improve light source light It is flux utilization, energy saving, at the same can to avoid light dispersion, save material etc., significantly improve LED lamp illumination product Matter.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further detail the utility model.
As shown in the figure, a kind of plane LED lamp reflector of the utility model, in one plane annular by several The plane mirror ring of distribution is formed, and the diameter of plane mirror ring is gradually reduced from outmost turns to innermost circle, ultimately forms one A pyramid facial plane, each plane mirror ring and plane are at an angle, and two neighboring plane mirror ring is in certain angle Degree connection makes the round reflective plane undulate of reflector.
The plane mirror ring is made of several plane mirrors 1, each 1 formation plane interconnected amongst one another of plane mirror Reflective mirror ring.Each plane mirror 1 is plane or curved surface, and edge is the outside of place plane mirror ring, the plane The edge of reflective mirror 1 is a fan-shaped or fan-shaped part.
The surface of each plane mirror 1 is coated with reflective material.
Under working condition, by the incident light 3 that LED light source 2 is sent out through annular spread in plane LED lamp reflector plane Plane mirror ring on plane mirror 1 reflect, the angle that is formed when being connected by each plane mirror ring carries out anti- It penetrates.
Due to anti-with 2 relative position of LED light source and plane mirror 1 and the difference and plane of reflector Plane Angle Light cup size difference is, it can be achieved that the distribution of the specified angle of luminous flux and specified magnitude.It is final to realize the reasonable of luminous flux Distribution.
It is cooperated by annular spread, compact arranged plane mirror in plane reflector plane, realizes that light leads to Reasonable distribution is measured, while optical requirement of the different lamps for light flux distribution is met, raising luminous flux of light source utilization rate, It is energy saving, while LED lamp illumination quality can be significantly improved to avoid dispersion, saving material of light etc..
