High-power LED (light-emitting diode) illuminating lamp

Abstract

The invention discloses a high-power LED illuminating lamp, which comprises a housing cover, a lens, a power supply, a radiator, a PCB (printed circuit board) and a plurality of groups of LED light sources, wherein the power supply and the LED light sources are electrically connected; the PCB is mounted on the radiator; the lens is mounted in a bayonet of the radiator and located below the PCB; the LED light sources comprise a plurality of LED components arranged side by side and mounted on the front side of the PCB; a plurality of reflection boards are also mounted on the radiator; each group of the LED light sources correspond to a reflection board; each reflection board is integrally manufactured through a flat plate, a plurality of anti-glare plates and arc boards which are located on two sides of the flat plate respectively and extend upwards; and each of the anti-glare plates is located between two adjacent LED components. According to the high-power LED illuminating lamp, the light extraction efficiency can be improved, and the dodging effect is achieved, so that discomfort for human bodies is reduced.

Description

technical field The invention relates to a high-power LED lighting fixture, which belongs to the technical field of LED lighting. Background technique Currently, glare refers to the sensation of annoyance, discomfort, or loss of visual performance caused by illumination in the field of vision that is far greater than the eye can accommodate. Glare light sources are divided into direct, such as sunlight, too strong lights, etc., and indirect, such as reflections from smooth surfaces (highway roads or water surfaces, etc.). According to the consequences of glare, there are mainly three types: discomfort glare, light adaptation glare and disability glare. Since LED is a point light source, if it is not used properly, it will easily produce glare, which will affect the physical and mental health of users. Most of the traditional lighting fixtures use circular lampshades, and the light from the LED light source passes through the circular lampshade before reaching the use area,...

AI Technical Summary

Problems solved by technology

Since LED is a point light source, if it is not used properly, it will easily produce glare, which will affect the physical and mental health of users.

Most traditional lighting fixtures use circular lampshades. The light from the LED light source passes through the circular lampshade before reaching the use area, resulting in a large amount of light loss and reducing the overall luminous efficiency of the lamps.
