Embodiment Construction

[0015] like figure 1 , figure 2 As shown, the present invention includes a lamp housing 1, LED light sources 33 and 34 and their driving power sources (not shown in the figure), the lamp housing 1 is a square structure, and the inner side of the lamp housing 1 is provided with an inwardly concave shape formed by a free reflective curved surface. Reflective cavity 2, the surface of the reflective cavity 2 is a free reflective curved surface, and the reflective curved surface is coated with a high-reflectivity material, which can increase the light-emitting efficiency of the lamp to more than 0.85. A beam 3 is fixed in the middle of the outlet end of the reflector cavity 2 of the lamp housing. The part corresponding to the center line of the reflector cavity 2 of the lamp housing and the beam 3 has a raised dividing line 11. The vertical distance from the dividing line 11 to the inner side of the beam 3 is 100mm~ 120mm, the cross section of the lamp housing reflection cavity o...

Abstract

The invention discloses a reflective LED grille lamp for illumination, which comprises a lamp shell, an LED light source and a driving power supply thereof, wherein the inner side of the lamp shell is provided with a sunken reflective cavity; at least one cross beam for fixing the LED light source is fixed at the outlet end of the reflective cavity of the lamp shell; and the LED light source is fixed on the inner side of the cross beam. Because reflective light emission is adopted and the light source is concealed on the inner side of the cross beam, glare is not produced; and a diffusion plate is not needed, the light loss is low, and the light emitting efficiency is high. In addition, the light emitting efficiency of the lamp can be further improved by effective heat dissipation design. The reflective LED grille lamp has high light efficiency and low power consumption, so the lamp can achieve good energy-saving effect; and meanwhile, the manufacturing cost of the lamp is relatively low.

Description

technical field [0001] The invention relates to a grille lamp for lighting, in particular to a reflective LED grille lamp. Background technique [0002] At present, grille lamps mainly include two kinds of embedded lamps with fluorescent lamps as light sources and LED light sources. The grille lamp with fluorescent lamp as the light source generally includes a frame-shaped lamp shell, a front cover, a rear cover, and a light source and electrical appliances fixed on the rear cover. The front cover is made of frosted glass or a matte light-transmitting plate. Tube. The main disadvantage of this type of lamps is that the light source is concentrated, and the light source is dazzling. To overcome this shortcoming, frosted glass (transmittance 40-60%) or a light guide plate with a matte surface (50-70%) with low light transmittance is usually used, which leads to serious light loss. [0003] There are two main types of grille lights using LED as the light source: side-emittin...
