According to the utility model, through the adoption of the reflecting surface of a scale structure, good light condensing performance is obtained; when the projection distance of a lamp is 10 m, the diameter of an illuminating spot is only 0.8 m; high uniformity is obtained, the uniformity of projection spots is obviously enhanced, and the uniformity of illumination can amount to 0.6; through the adoption of a surface shape suitable for condensing lights and the proper scale structure, a lighting effect of the reflecting cup can amount to 97%; and small diameter is obtained and requirements on miniaturization are satisfied; and the mall-caliber LED scale reflecting cup disclosed by the utility model is suitable for the reflecting cups used for pocket LED flashlights, electric bicycles, head lamps and so on.

Description

A kind of LED scale and shell reflector of small-bore, little beam angle
Technical field
The utility model relates to technical field of semiconductor illumination and secondary optics technical field, relates in particular to a kind of LED scale and shell reflector of small-bore, little beam angle.
Background technology
LED is the very little semiconductor devices of a kind of profile, when electric current can send versicolor light during through it.Glow color depends primarily on the chemical composition of the luminous composition of led chip, can be deployed into as required that white light or other are various to have coloured light.Led light source is nontoxic because of no mercury, power requirement is low, no electromagnetic pollution, no harm ray, and has advantages such as energy-saving and environmental protection, life-span are long, and recently, led light source especially is applied among the portable lamp as lighting source extensively utilization.But general reflector is because of bore is big, optically focused property is poor, the uniformity is low, causes illuminating effect poor.
The utility model content
To above-mentioned prior art, the technical problem that the utility model will solve is: existing reflector is because of bore is big, optically focused property is poor, the uniformity is low, causes illuminating effect poor.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of LED scale and shell reflector of small-bore, little beam angle comprises reflecting surface and annular bottom surface, and the LED lamp is arranged at annular bottom surface central authorities, it is characterized in that, the zone of said reflecting surface for the reflector bottom to the reflector top; Reflecting surface is made up of the number of plate-shaped scale and shell, and to the reflector top multistage scale and shell being arranged at the bottom of the reflector, each section scale and shell size is from being radial increase to the reflector top at the bottom of the reflector; Each section has a multi-disc scale and shell on the cup reflecting surface circumference, scale and shell equal and opposite in direction in same section.
On the circumference of said reflecting surface, be evenly arranged into 80 row scale and shell reflectings surface.
The size of said reflecting surface is: diameter is 31.5 ~ 32.5 millimeters, highly is that 32.5 ~ 33.5 millimeters, bottom surface opening diameter are 7.5 ~ 8.5 millimeters.
Closely arrange between said scale and shell and connect.
Said scale and shell is the hexagon plane.
The width dimensions of the outermost every row scale and shell of reflecting surface is 1.25 ~ 1.35 and 0.85 ~ 0.95 millimeters, and length dimension is 16.9 ~ 17.2 millimeters.
The beam angle of reflector is less than 7 degree.
Reflector can use the LED of 115 degree ~ 125 degree, 1W ~ 5W to make light source.
Compared with prior art, the utlity model has following beneficial effect:
1, it is simple and practical, and bore is little, meets the requirement of miniaturization, is applicable to the reflector that pocket LED flashlight, electric bicycle, head lamp etc. use;
2, through the reflecting surface of scale and shell structure, the optically focused performance is good, and when the projection distance of light fixture was 10 meters, the spot diameter that illuminates was merely 0.8 meter; The uniformity is high, and the uniformity of projected spot significantly improves, and illuminance uniformity can reach 0.6; Adopt face shape that is fit to optically focused and the scale and shell structure that is fit to, make the light efficiency of reflector can reach 97%.
