Problems solved by technology
Although this structure can improve the luminous flux of the LED when it is working, for some occasions, such as outdoor lighting or road lighting, LED lights with this structure have certain defects. Symmetrically distributed and non-polarized light, which will cause most of the light to not directly irradiate the effective lighting area, thereby reducing the effective utilization of light

Embodiment Construction
[0022] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0023] see Figure 1~Figure 2 , the polarized LED bracket 1 of the present invention comprises an anode pin 10, a cathode pin 11, an inner reflector 12 of an asymmetric structure is stamped on the cathode pin 11, the inner reflector 12 is bowl-shaped, and the mouth of the inner reflector 12 is The diameter of the inner reflector 12 is greater than the diameter of the bottom of the bowl. The surface of the inner reflector 12 is an inclined surface relative to the bottom of the bowl. The relatively low end of the bowl is close to the anode pin, and the relatively high end of the bowl is far away from the anode pin. Reflector 12 bowl bottom. The inner wall of the internal reflector 12 is an arc surface, and the cathode pin 11 extends toward ...

The invention discloses a polarized light type LED (light emitting diode) support which comprises an anode pin and a cathode pin, wherein the upper part of the cathode pin is provided with an inner reflector, the inner reflector is bowl-shaped, the diameter of a bowl opening of the inner reflector is larger than that of a bowl bottom of the inner reflector, the plane of the bowl opening of the inner reflector is an inclined surface opposite to the bowl bottom, one lower end of the bowl opening is close to an anode, and one higher end of the bowl opening is far away from the anode. The inner reflector of the LED support provided by the invention is bowl-shaped, the plane of the bowl opening of the inner reflector is an inclined surface, and the inner reflector is asymmetric, so that the emergent direction of the emergent light can be changed and a certain polarized light can be realized due to the structure of special inner reflector, therefore, the polarized light design of a packaging lens can be conveniently provided, and a polarized light lamp bead which accords with different lighting places can be manufactured.
Description
technical field [0001] The invention relates to the technical field of LEDs, in particular to a polarized LED bracket, a lamp bead and a method for manufacturing the polarized LED bracket. Background technique [0002] LED is used more and more widely, and LED lamps are gradually favored by people. The design of LED bracket is an important link to improve the light utilization rate of LED lamp beads. The unique bracket structure can make LED lamp beads have unique optical effects, so that Its application in some lighting fields has more advantages. At the same time, improving the utilization of light also means reducing energy consumption. [0003] The structure of the LED bracket has a certain influence on the luminous intensity and luminous angle. For example, the Chinese utility model patent with the patent number "201120060407.5" and the patent name "LED bracket" discloses an LED bracket, which includes an anode pin and a cathode pin. Shape, the diameter of the inner ...
