led ring lighting light distribution structure

Abstract

The invention applies to a light emitting diode (LED) lamp installation structure, and discloses an LED annulus illumination light distribution structure. The LED annulus illumination light distribution structure comprises an LED lamp body, a reflector and a base seat, wherein the base seat is provided with a taper side portion which is arranged around the center position of the base seat and inclines at an angle of 95-120 degrees relative to the horizontal plane, the LED lamp body is fixed on the outer wall of the taper side portion, the reflector comprises a first reflection portion and a second reflection portion, the first reflection portion is provided with a reflecting surface which inclines at an angle of 70-80 degrees relative to the center line of the base seat, the top of the second reflection portion is connected with the first reflection portion, and the side portion of the second reflection portion is arranged on the taper side portion in fit mode and provided with an opening for exposing the LED lamp body in penetration mode. According to the LED annulus illumination light distribution structure, effective distribution of irradiation directions of light rays is achieved by ingeniously designing the shape of the side portion of the base seat and ingeniously setting positions of the first reflection portion and the second reflection portion on the reflector, and accordingly the irradiation area of a lamp is enlarged, visual effects of lamp illumination are improved, and uniform illumination effects and efficient illumination effects of the lamp can be achieved in a certain range.

Description

technical field [0001] The invention belongs to the field of installation structures of LED lamps, and in particular relates to a light distribution structure of LED ring lighting. Background technique [0002] At present, incandescent lamps or energy-saving lamps are mostly used for road lighting in domestic factories, mines, freight yards, port terminals, etc., and lighting for courtyards and lawns. As people pay more and more attention to energy saving, incandescent lamps have been included in the elimination list by the National Development and Reform Commission. From October 1, 2012 to September 30, 2012 as a transition period; from October 1, 2012, the sale and import of incandescent lamps of 100 watts and above for general lighting are prohibited; from October 1, 2016, the sale and import of 15 Incandescent lamps for general lighting of watts and above. [0003] At the same time, when the ballast used in energy-saving lamps generates instantaneous high voltage, it w...

Problems solved by technology

[0004] Moreover, in the light distribution structure of incandescent lamps or energy-saving lamps, a sunshade is generally used to irradiate the light on the ground as much as possible. In this way, on the one hand, it is not conducive to the large-area lighting of the lamps, and reduces the landscape effect of the lamps. On the other hand, it cannot According to the specific needs to achieve a uniform lighting effect within a certain range, it is also impossible to achieve high-efficiency lighting within a certain range according to specific needs, thereby reducing the lighting effect of the lamps
