Abstract
The utility model provides a light-reflecting cup of a multi-layer step type tunnel lamp, which belongs to the field of light-emitting diode (LED) tunnel lighting devices. The light-reflecting cup structurally comprises a base. A blind hole is vertically arranged at the center of the base, and the lateral wall of the blind hole is in a step inner wall shape. The width of the step inner wall is reduced progressively from top to bottom, and a light-reflecting surface is arranged on the vertical surface of the step inner wall. A front surface plate is arranged along the periphery of the blind hole at the upper end of the base, namely the upper end of the blind hole. The front surface plate is formed by connecting four plate bodies in end-to-end mode, pits are arranged in the middle of the four plate bodies, and clamp springs are symmetrically arranged on the base below the front surface plate. Compared with the prior art, the light-reflecting cup has the advantages of being reasonable in design, simple in structure, little in luminous energy loss, high in reflectivity and the like.
Description
Technical field
The utility model relates to a kind of LED tunnel illumination device, specifically a kind of stage construction staged Tunnel Lamp reflector.
Background technology
Present most of LED tunnel illumination light fixture all adopts lens as secondary light-distribution.Using lens to do secondary light-distribution is that the lamp pearl is wrapped in the lens outside, and the emit beam refraction of scioptics of light source changes the light direction of light fixture, thereby realizes the equally distributed purpose of light in the irradiation area.The optical energy loss of lens secondary light-distribution is bigger, and the efficiency of light energy utilization is low, influences the heat radiation of lamp pearl, and the light fixture light decay is fast, and the life-span reduces, and the lens installation is loaded down with trivial details, is prone to come off.
Summary of the invention
The technical assignment of the utility model is the deficiency to prior art, and a kind of stage construction staged Tunnel Lamp reflector reasonable in design, simple in structure is provided.
The utility model solves the technical scheme that its technical problem adopted: comprise base, said center vertically is provided with blind hole, and the blind hole sidewall is set to the ladder inner wall shape, and ladder inwall width successively decreases from top to bottom successively; The vertical plane of ladder inwall is provided with reflective surface; Said base upper end is that the blind hole upper end is provided with front plate around blind hole; Front plate is to be joined end to end to connect by the plate body that four middle parts are provided with pit to form, and the front plate below is to be symmetrically arranged with jump ring on the base.
The blind hole bottom is that base is provided with led light source, and the rising angle of reflective surface corresponding light source is 5 degree.
The front plate middle part surrounds square through hole and matches with blind hole upper end size.
Jump ring is provided with a pair of.
This reflector adopts the ABS plastic injection mo(u)lding, aluminizes in the surface.
Interior reflective surface is that the little reflective surface of multi-level ladder is formed, and what increase progressively step by step is arranged in the reflector inboard, led light source is emitted beam behind reflective surface, reflect, and changes the direction of original light.
The design principle of the utility model is utilized the principle of reflection of light, and the lighting angle of led light source self is about 170 degree, and through behind the reflection multilayer of reflector, rising angle is adjusted into 80 degree.The led light source light of corresponding 5 degree of the little reflective surface of each ladder of reflector, make light that led light source produces by system be assigned to area to be illuminated territory, space, make space illumination more even.Reflector adopts the mode of aluminizing, and optical energy loss is few, and reflectivity is up to more than 90%.
The utility model compared with prior art, the beneficial effect that is produced is:
Use the reflector of stage construction staged reflective structure low as the LED Tunnel Lamp light loss of secondary optics luminous intensity distribution, bright dipping is even, and optical energy loss is few, and reflectivity is high, does not influence the led light source heat radiation.Material thermal resistance is good, and is not yielding, and reflector directly is stuck on the special stand, install simple and convenient, and difficult drop-off.

Shown in accompanying drawing, a kind of stage construction staged Tunnel Lamp reflector of the utility model, its structure comprises base 4, and said base 4 centers vertically are provided with blind hole 2, and blind hole 2 sidewalls are set to the ladder inner wall shape, and ladder inwall width successively decreases from top to bottom successively; The vertical plane of ladder inwall is provided with reflective surface 5, and said base 4 upper ends are that blind hole 2 upper ends are along blind hole 2 four
Be provided with front plate 1 week, front plate 1 is to be joined end to end to connect by the plate body that four middle parts are provided with pit to form, and front plate 1 below is to be symmetrically arranged with jump ring 3 on the base 4.
Jump ring 3 is provided with a pair of.
This reflector adopts the ABS plastic injection mo(u)lding, aluminizes in the surface.
A=5 ° of angle ∠ among the figure between the incident ray, ∠ a are 5 ° of light that light source sends.∠b1=∠b2，∠c1=∠c2。Wherein incident ray 7 becomes outgoing through behind the reflective surface
Light 8.
Reflector support 9 is fixed on the lamp radiator, and reflector then is fixed on the reflector support 9 through jump ring 3.Each lamp pearl is joined a reflector, and 7 on each support is gone up 7 reflectors are installed, and 7 reflectors constitute a module.
Except that the described technical characterictic of specification, be this professional's known technology.
