Concentrating LED

Abstract

The present invention discloses a concentrating type light emitting diode. The concentrating type light emitting diode comprises a diode body which is internally provided with a cathode and an anode, and the concentrating type light emitting diode is characterized in that the cathode is provided with a concave surface-shaped concentrating groove, an opening is arranged at the bottom of the concentrating groove, and the anode is arranged at the opening of the bottom of the concentrating groove; and the concave surface of the concentrating groove is provided with a plurality of emission bowls, and wires are connected between the anode and each emission bowl. The emission bowls are symmetrically arranged on the concave surface of the concentrating groove around the center of the concave surface. The concave surface of the concentrating groove is a concave cambered surface or a tapered concave surface. The radius of curvature of the concave cambered surface is 1-1.5mm. The included angle between two opposite sides of the tapered concave surface is 45-60 degrees. The concave surface of the concentrating groove is plated with a silver layer. The upper end of the anode is a turbinate structure. The wires are sliver wires. The concentrating type light emitting diode is simple in structure and high in concentrating capability and can generate higher illumination intensity. The design of the multiple emission bowls can reduce the production disability rate and the usage disability rate and reduce the production difficulty and the usage difficulty.

Description

technical field [0001] The present invention relates to a concentrating light-emitting diode. Background technique [0002] With the progress of high-brightness and polychromatic light-emitting diodes, the application field is also expanding. From the lower luminous flux indicator to the display screen, from the outdoor display to the medium luminous flux power signal lamp and the white light source for special lighting, and finally Developed to the high luminous flux general lighting source in the upper right corner. The year 2000 is the dividing line of time. In 2000, the signal display problems and lighting problems of all colors have been solved, and special lighting applications of low and medium luminous flux have been started, and as general lighting The application of high luminous flux white light lighting seems to take time, and it is necessary to further increase the luminous flux before it can be realized. Of course, this is also a process, which will be graduall...

AI Technical Summary

Problems solved by technology

[0003] Existing light-emitting diodes often have only one light-emitting point, and the diode can no longer be used after this point is damaged, and the light-gathering performance of the diode is poor, and the luminous brightness is poor
