Abstract

The utility model discloses an LED reflecting cup, which is in the shape of a lidless quasi-inverted quadrangular frustum pyramid. Every two opposite surfaces are the surfaces formed by translating two symmetric parts of an identical parabola; wherein two opposite surfaces with long side lengths are higher than two opposite surfaces with short side lengths; and four fixed columns connected with a circuit board are arranged on four feet on a bottom surface thereof. The LED reflecting cup covers each LED of an LED street lamp or an LED tunnel lamp according to the same method, can change a light-emitting angle of each LED, so as to form oval-shaped or rectangular light spots, thereby achieving the purpose of the even light distribution within a certain irradiation range required for the LED street lamp and the LED tunnel lamp. The LED reflecting cup has the advantages that the light contraction is more reasonable; a beam angle is about 60 degrees; the highest illumination is improved by one time; and the illumination is greatly improved. An LED lamp for mounting the LED reflecting cup has the advantages of high light-emitting efficiency and convenient mounting, is an independent component and inserted in the circuit board, and can be suitable for the combination of the lamp with different number of LEDs, with flexible application.

Description

A kind of LED reflector

One, technical field

The utility model relates to the reflector that a kind of LED light fixture is used.

Two, background technology

At present, reflector is widely used on flashlight and the light fixtures such as shot-light, Down lamp, and these reflectors are tapered structure, and the hot spot of reflection is round.It is ellipse or rectangle that LED street lamp, LED Tunnel Lamp require hot spot, and the spotlight effect of these reflectors can not be satisfied the demand at present.

Three, summary of the invention

The purpose of this utility model solves the above-mentioned problems in the prior art exactly, and it is ellipse or rectangle that a kind of hot spot of reflection is provided, and is evenly distributed the LED reflector that illuminance is high.

For achieving the above object, the technical solution of the utility model is: a kind of LED reflector, it is shaped as the class shape of falling the truncated rectangular pyramids of uncovered, per two opposite faces are the face that same parabolical two symmetric part translations form, two long opposite faces in limit opposite face height shorter wherein than two length of sides, have a hole that holds LED on its bottom surface, on its bottom surface four pin four fixed legs that are connected with wiring board are arranged.

Above-mentioned described two long opposite faces in limit of the present utility model opposite face shorter than two length of sides exceeds 3-4mm.

The inwall of above-mentioned described the utility model reflector is arranged to a plurality of arc male and fomale(M﹠F)s with the prism principle as required.

The material of making above-mentioned described the utility model reflector uses the surface to synthesize fire retardant by the ABS that ion beam sputtering deposition technology plates non-conductive material reflective membrane, and its reflecting effect is good, and coating has alcohol wipe and do not come off, and boiling water boils non-discoloring advantage for a long time.

Cover on the utility model on each LED of LED street lamp or LED Tunnel Lamp according to Same Way, can change the rising angle of LED, make it to form ellipse or rectangular light spot, reach the purpose of requirements such as LED street lamp, LED Tunnel Lamp even beam split in certain range of exposures.Two long opposite faces in limit exceed the short opposite face of two length of sides and use its LED street lamp or Tunnel Lamp more reasonable what shrink along road vertical direction glazing, beam angle is about 60 °, its maximum illuminance doubles than the LED street lamp or the Tunnel Lamp of the same LED arrangement mode that this reflector is not installed, and has improved illuminance greatly.LED lamp luminescence efficient height of the present utility model is installed, easy for installation.The utility model is an individual components, pegs graft in the circuit board, goes for the light fixture combination of different LED quantity, uses flexibly.

Four, description of drawings

Below in conjunction with accompanying drawing to the utility model to further description:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a left view of the present utility model;

Fig. 3 is a vertical view of the present utility model;

Fig. 4 is the AA cutaway view of Fig. 1;

Fig. 5 is the BB cutaway view of Fig. 1.

Five, the specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, present embodiment is shaped as the class shape of falling the truncated rectangular pyramids of uncovered, per two

opposite faces

3 and 6,1 and 5 are the face that same parabolical two symmetric part translations form, its inwall is arranged to a plurality of arc male and fomale(M﹠F)s 4 with the prism principle as required, the short

opposite face

3,6 of 1,5 to two length of sides of the long opposite face in two limit exceeds 3.6mm, perhaps 3mm or 4mm, have a hole 7 that holds LED on its bottom surface, the fixed leg 2 that is connected with wiring board is arranged on four pin of the outer surface of its bottom surface.The material of making present embodiment uses the surface to be plated the synthetic fire retardant of ABS of non-conductive material reflective membrane by ion beam sputtering deposition technology.
