Combined-type lamp based on fisheye light distribution structure

Abstract

The invention discloses a combined-type lamp based on a fisheye light distribution structure. The combined-type lamp comprises a radiator, a surface ring, a lamp holder, an LED light source, a reflection cup and a lens; the lamp holder is fixed to the tail portion of the radiator and used for being installed on a socket, an inner cavity is formed in the radiator and used for assembling of the LED light source, the reflection cup and the lens, and the LED light source is installed on the illuminated face of the lens, the lens is installed at a light inlet of the reflection cup; and an optic is clamped at an end opening of the top of the reflection cup through the surface ring. According to the combined-type lamp based on the fisheye light distribution structure, a concave-convex treatment technology is suppressed on the optical mirror surface or the lens surface of an LED lamp, by presetting a design technology of a series of tiny concave-convex points, the surface of the reflection cup is composed of countless ridge surfaces, the outer surface of the lens is composed of many tiny convex points, and thus an ideal optical system is jointly formed; and through design, emergent light of the lamp is good in light intensity and even and soft in light ray within a controllable range.

Description

technical field [0001] The invention relates to an LED lamp, especially a combined lamp based on a crystal point light distribution structure. Background technique [0002] For existing high-power LED spotlights, most of the LED light sources used are point light sources, and the light beams emitted are relatively concentrated, which will produce dazzling glare during use, easily cause visual fatigue, and cause discomfort to users. In order to prevent glare, the utility model patent "High Power LED Spotlight" with the patent No. ZL200920131954.0 in the prior art discloses such an LED spotlight. Connecting terminals, a driving power supply arranged in the lamp body and electrically connected to the connecting terminal, an LED light source arranged in the lamp body and electrically connected to the driving power supply, and a lens set on each LED chip of the LED light source, Wherein, the lens has a light-emitting surface, a truncated cone is formed downward from the light-em...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the problems of low beam angle accuracy, low light output efficiency, many halos and glare of lamps, and difficult heat dissipation of high-power LED lamps, which are common in reflective lamps, and provides a combined lamp based on crystal point light distribution structure.
