LED illuminating lamp

Abstract

The invention discloses an LED illuminating lamp comprising a lamp body, a high-power LED light source arranged on the outer wall of a lamp body assembly, and a heat sink. The inner wall of the lamp body is a highly reflective surface; the lamp body comprises a plurality of assemblies used for fixing the LED light source; the inner wall of each lamp body assembly is provided with an arc reflectingsurface; and the luminous part of the LED light source is arranged in the inner cavity of the arc reflecting surface. Light emitted from the LED light source can be transmitted to illumination spaceonly after being reflected by the arc reflecting surface or reflected by the arc reflecting surface and the inner wall of the lamp body for many times, thus the glare problem caused by the LED light source is effectively solved. The LED light source is arranged on the outer wall of the lamp body, and therefore, the LED heat is easy to transmit by the heat sink, the work temperature of the LED light source is reduced, the stability of the light source is enhanced and the service life is prolonged. The invention has the advantages of simple structure, convenient processing, good radiating effect, even illumination and the like and can be widely used for interior illumination occasions and the like.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED lighting fixture. Background technique [0002] With the rapid development of LED technology, high-power LED preparation technology has become increasingly mature. LED light source has become the best light source choice to replace traditional lighting sources because of its advantages such as high luminous flux, long life, small structure, safety, high efficiency, and energy saving. . The current LED lighting fixtures generally concentrate a large number of ordinary small LED tubes or multiple power tubes in one lamp, and most of them adopt a closed lamp structure design, which makes the heat dissipation problem of LEDs very prominent and seriously affects the performance of LED lamps. Light source stability and service life. On the other hand, the existing LED lamps generally use the LED light source to emit directly into the lighting space (generally the ground),...

Problems solved by technology

The current LED lighting fixtures generally concentrate a large number of ordinary small LED tubes or multiple power tubes in one lamp, and most of them adopt a closed lamp structure design, which makes the heat dissipation problem of LEDs very prominent and seriously affects the performance of LED lamps. Light source stability and service life

On the other hand, the existing LED lamps generally use the LED light source to emit directly into the lighting space (generally the ground), because the light directly emitted by the LED is not uniform, which is irritating to the human eye and seriously affects the lighting effect of the LED lamp. , It is easy to cause visual fatigue or even vision loss. This is the light pollution that often exists in LED lamps - the glare problem
