Embodiment Construction

[0024] refer to figure 1 As shown, it is a combined lamp based on the crystal point light distribution structure of the present invention, including a radiator 10, a face ring 20, a lamp holder 30, an LED light source, a reflector 40 and a lens 50, and the lamp holder 30 is fixed on the tail of the radiator 10 and used Installed in the socket, the radiator 10 has an inner cavity and the inner cavity is used to assemble the LED light source, reflector 40 and lens 50, the LED light source is installed on the light receiving surface of the lens 50, and the lens 50 is installed on the reflector 40 The top port of the reflector 40 is clamped with a lens by the face ring 20, wherein the LED light source is a COB light source.

[0025] The light emitted by the LED light source is firstly refracted and concentrated by the lens 50, and then enters the reflector 40 for multiple reflections for uniform treatment to reduce halo and glare, and finally exits the lens.

[0026] Such as fi...

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...
