Abstract
The utility model relates to a light reflecting cup comprising a light reflecting face, wherein the light reflecting face is a step-shaped light reflecting face. The utility model provides a light reflecting cup with wide application range and good light uniformity.
Description
Technical field
The utility model relates to a kind of reflector.
Background technology
At present at some light fixtures, especially during the luminous intensity distribution of LED light fixture, substantially all adopt the pattern of symmetrical luminous intensity distribution, utilize the secondary light-distribution technology of existing reflector, its light source beam angle generally is controlled in 60 °, this luminous intensity distribution pattern is also inapplicable when street lamp uses, and the reflector of street lamp is asymmetrical luminous intensity distribution.And for the high canopy lamp of beam angle greater than 60 °, its luminous intensity distribution pattern but is a symmetric form, there is no suitable reflector and comes luminous intensity distribution.
The utility model content
In order to solve the above-mentioned technical problem that exists in the background technology, the utility model provides a kind of applied widely, reflector that optical uniformity is good.
Technical solution of the present utility model is: the utility model provides a kind of reflector, comprises reflective surface, and its special character is: reflective surface is stair-stepping reflective surface.
Above-mentioned stair-stepping reflective surface comprises ladder reflective surface and downstairs reflective surface; The described optical focus that goes up ladder reflective surface and downstairs reflective surface does not overlap.
Above-mentioned stair-stepping reflective surface is two or more.
Above-mentioned reflective surface is a curved surface.
The utility model has the advantages that:
1, applied widely.Reflector inner surface provided by the utility model is that a plurality of free form surfaces are composited, and the focus of every section free form surface, does not overlap, behind this kind of reflector luminous intensity distribution, the beam angle of light fixture can reach 80 °, can also adjust the luminous intensity distribution angle according to real needs, and the scope of application is wide.
2, optical uniformity is good.Reflector provided by the utility model adopts two sections different free form surfaces, utilizes the difference of two curved surfaces to focus on, and light is assigned on the shadow surface that needs, and connects by chain-wales between two sections curved surfaces.Led light source is positioned at centre position, reflector bottom, can be divided into two parts through the source light of reflector, and a part is not for via the direct emergent light of reflector, and a part is through the reflective emergent ray of reflector.Energy of reflection light, respectively through two free form surface outgoing, each free form surface reverberation focus does not overlap, and utilizes this characteristic can realize the design of light-emitting uniformity easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model provides a kind of reflector, comprises reflective surface, and this reflective surface is stepped, and this stair-stepping reflective surface comprises ladder reflective surface and downstairs reflective surface; The optical focus of last ladder reflective surface and downstairs reflective surface does not overlap.Stair-stepping reflective surface can be two or more.
Referring to Fig. 3, the utility model provides a kind of preferable reflector embodiment, the reflective surface of this reflector comprises ladder reflective surface 1 and downstairs reflective surface 2, last ladder reflective surface 1 is curved surfaces of two sections different optical focus with downstairs reflective surface 2, utilize two sections differences, the different free form surface that focuses on, light is assigned on the shadow surface that needs, connects by chain-wales between two sections curved surfaces.
The utility model is when concrete the use, and led light source is positioned at centre position, reflector bottom.Source light can be divided into two parts, a part is not for via the direct emergent light of reflection shield, a part is through the reflective emergent ray of reflection shield, energy of reflection light, through last ladder reflective surface 1 and 2 outgoing of downstairs reflective surface, each free form surface reverberation focus does not overlap, and utilizes this characteristic can realize the design of light-emitting uniformity easily.
Claims (4)
1. a reflector comprises reflective surface, it is characterized in that: described reflective surface is stair-stepping reflective surface.
2. reflector according to claim 1 is characterized in that: described stair-stepping reflective surface comprises ladder reflective surface and downstairs reflective surface; The described optical focus that goes up ladder reflective surface and downstairs reflective surface does not overlap.
