Abstract
The utility model discloses a light emitting diode (LED) scute reflection cup with small light emitting angle. The LED scute reflection cup with the small light emitting angle has a multi-layer scute structure; scutes are increased radially from the bottom of the reflection cup to the top of the reflection cup; each layer of the scutes is equally divided into a plurality of parts; each equal part is provided with a line of scute structures; and the distance between the bottom part of the reflection cup and the light emitting surface of an LED lamp is 2.0 to 3.5 mm, and preferably 2.98 mm. Through the reflection surface with the scute structure, the LED scute reflection cup with the small light emitting angle has high condensation performance; when the projection distance of the lamp is 10 m, the diameter of an illuminated light spot is only 0.4 m; the uniformity is high, the uniformity of the projected light spot is improved remarkably, and the illuminance uniformity can reach 0.6; and by adopting a surface shape suitable for condensing and a suitable scute structure, the light efficiency of the reflection cup can reach 97 percent.
Description
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 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 beam angle is big, 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 little beam angle is characterized in that the cup 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, and the distance between the bottom of scale and shell reflector and LED lamp light-emitting area is 2.0～3.5 millimeters.
Distance between the bottom of said scale and shell reflector and LED lamp light-emitting area, optimum is 2.98 millimeters.
Said each scale and shell is the hexagon plane, adjacent segment scale and shell interlaced arrangement.
Outermost each scale and shell, its width dimensions are 1.48 and 1.41 millimeters, and length dimension is 37.8 millimeters.
The reflector base diameter is 22.5 millimeters, and top diameter is 52 millimeters.
The beam angle of reflector is less than 3.5 degree.
Use the LED of 115 degree ~ 125 degree, 1W ~ 10W to make light source.
Compared with prior art, the utlity model has following beneficial effect:
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 0.4 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 94%.
Description of drawings
Fig. 1 is the installation diagram of the utility model and LED;
The curve of light distribution of Fig. 2 the utility model;
Reference numeral is: 1 is that LED lamp, 2 is scale and shell.
The specific embodiment
To combine the accompanying drawing and the specific embodiment that the utility model is done further to describe below.
A kind of LED scale and shell reflector of little beam angle is characterized in that the cup 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, and the distance between the bottom of scale and shell reflector and LED lamp light-emitting area is 2.0～3.5 millimeters.Distance between the bottom of said scale and shell reflector and LED lamp light-emitting area, optimum is 2.98 millimeters.Said each scale and shell is the hexagon plane, adjacent segment scale and shell interlaced arrangement.
In conjunction with illustrated in figures 1 and 2, reflecting surface adopts 19 layers of ascending scale and shell structure, has improved the illuminance uniformity of projected area, and at 10 meters projector distance, illumination uniformity can be greater than 0.6.With lambert's LED type curve of light distribution, 115 the degree ~ 125 the degree beam angle, convert to the light-focusing type curve of light distribution, less than 3.5 the degree beam angle.The illuminating effect of light fixture is reached: projection distance is 10 meters, and the spot diameter that illuminates is merely 0.4 meter, and light efficiency can reach 94%.The utility model can use 1W, 3W, 5W, and the 10W beam angle is that the LED of 115 degree ~ 125 degree makes light source.Lamp cup is of a size of: diameter is 52 millimeters, highly is 31.65 millimeters, and the bottom surface opening diameter is 22.5 millimeters.Reflector can be used the manufacturing of specular aluminium spinning, also can use plating total reflection film manufacturing after the ABS plastic injection moulding.
