LED grille lamp

Abstract

The embodiment of the invention discloses an LED grille lamp which comprises a long light box with an opening on one surface; a stripe-shaped metal substrate is arranged on the axis in the length direction in the light box; the surface of the metal substrate is vertical to a plane on which the opening of the light box is arranged; a plurality of LED light sources are distributed on the two surfaces of the metal substrate; the light outlet direction of the LED light source is vertical to the metal substrate and is outward; one free curved surface reflector is respectively arranged correspondingly to each LED light outlet surface, and the light given off by the LED light sources is reflected by the curved surfaces of the free curved surface reflectors and is irradiated outwards from the opening of the light box. The LED grille lamp can re-distribute space light energy for the light given off by the LED light sources so as to achieve the purpose of improving the illumination uniformity.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED grid lamp. Background technique [0002] As a new type of environment-friendly light source, LED is being more and more widely used in TV backlight, general lighting, and vehicle lighting. The existing conventional grid lamps use grid reflectors and fluorescent tube light sources. Due to environmental protection and energy saving considerations, more and more households have begun to use LED tubes to directly replace fluorescent tubes as the light source for grid lamps. However, the existing grid lamps of LED light sources all have the disadvantages of large space glare and low uniformity of illuminance on the illuminated surface due to limited space light distribution capability. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide an LED grid light. The light emitted by the LED light source can be ...
