Embodiment 1

[0032] Such as figure 1 As shown, the present invention provides a high-efficiency anti-glare lighting fixture. The lighting fixture includes a trapezoidal lamp body 3 with a curved surface, and a light source module 4 is installed on the bottom plate inside the lamp body 3; A grid plate 7, an anti-blue light diffusion plate 6 is provided between the light source module 4 and the grid plate 7, and a frame 5 is installed outside the lower part of the lamp body 3, and the frame 5 fixes the grid plate 7 and the lamp body 3; the lamp body 3 and the lamp body The diffusion plate 6, the grid plate 7 and the frame 5 form a closed space, and the light source module 4 is covered inside. A connecting rod 2 and a ceiling cup 1 are also installed on the outside of the lamp body 3 . The surface of the grid plate is a white matt surface, made of ABS, PC and other heat-resistant deformation materials.

[0033] Such as figure 2 As shown, the present invention provides an anti-glare grille...

Embodiment 2

[0044] Embodiment 2 adopts a structure similar to that of Embodiment 1, wherein the light source module includes three parallel LEDs as light sources, and the luminous flux (lm) is 2700. An anti-blue light diffusion sheet and an anti-glare grille are installed sequentially below the optical module.

[0045] Embodiment 2 adopts a grid plate structure similar to that of Embodiment 1. In order to further optimize the uniform glare index, the adjacent lateral spacing on both sides of the grid plate structure is optimized and adjusted to 12mm and 17.5mm from Example 1. 14mm, the other dimensions remain unchanged.

[0046] After testing, the overall light efficacy reduction of the lighting fixtures in Example 1 and Example 2 is less than 1%, and the unified glare index UGR is lower than 16, which is far superior to the current national standard requirement of unified glare index UGR19, and can achieve high-efficiency lighting. The illuminance distribution is uniform, the anti-glare...

Abstract

The invention discloses an anti-dazzle illumination lamp. The anti-dazzle illumination lamp comprises a light source module and an anti-dazzle grating plate; the anti-dazzle grating plate comprises multiple transverse separating plates and multiple longitudinal separating plates; the transverse distances among the longitudinal separating plates adopt the non-uniform distance structure; and the longitudinal distances among the transverse separating plates adopt the non-uniform distance structure. The heights, in the direction perpendicular to the grating plates, of the longitudinal separating plates and the transverse separating plates adopt the non-uniform height structure.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to a classroom lighting fixture with an anti-glare grid plate. Background technique [0002] At present, most of the lighting fixtures in classrooms and offices of primary and secondary schools use bare lamps, which will produce glare under direct light, which has a certain impact on people's eyes and causes eye discomfort and visual fatigue. According to the impact of glare on visual function, it can be divided into disability glare or psychological glare. Disabling glare can cause visual disturbances in viewing objects, and physiologically affect the visual organs. Psychological glare refers to the feeling of discomfort under its effect for a long time, resulting in a bad feeling psychologically. When the glare is severe, the eye muscles will be overly tense, easily distracted, and unable to concentrate. Studying or working in this environment for a long time will cause great da...
