Problems solved by technology

Multiple point light sources on the wiring board form a shadow area where the LED light cannot intersect, so that the LED light cannot be cross-mixed evenly, and glare will still occur
[0004] The above-mentioned LED light does not cross, and has the following major disadvantages: 1) LED particles can be seen when working, which is dazzling; 2) It cannot be shadowless, and there are obvious dark spots on the mask; 3) The light efficiency is not high, Below 60lm / W

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0021] Such as figure 1 Shown: LED shadowless lamp, including lamp panel 1, diffuser plate 2 and LED light source 3, the opening of lamp panel 1 is closed by diffuser plate 2; LED light sources 3 are arranged in matrix at the bottom of lamp panel 1, as shown figure 2 As shown, the matrix of LED light sources 3 is arranged in a square, such as image 3 As shown, the matrix of LED light sources 3 is arranged in a rectangle; the horizontal distance between two horizontally adjacent LED light sources 3 is A, and the longitudinal distance between two vertically adjacent LED light sources 3 is B.

[0022] combine Figure 4 , Figure 5 As shown, the light emitted by two laterally adjacent LED light sources 3 forms an intersection, and the light emitted by two vertically adjacent ...

Abstract

The invention relates to a light emitting diode (LED) shadowless lamp. The lamp comprises a lamp disc, a diffusion plate and LED light sources, wherein an opening of the lamp disc is sealed by the diffusion plate; and the diffusion plate 2 is positioned at a position which is one or two times the longitudinal distance of two adjacent LED light sources (3) away from the adjacent LED light sources (3), so that light rays emitted by the LED light sources are crossed and emitted, the adjacent LED light sources cannot form a shadow on the diffusion plate, and the lamp has the advantages that: the emitted light rays are uniform, LED light source particles cannot be seen during work, and a shadowless effect is achieved.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED shadowless lamp. Background technique [0002] Existing LED (Light Emitting Diode, light-emitting diode) lamps and light sources are mostly point light sources, which are prone to dazzling glare. Watching for a long time will cause fatigue and even cause vision loss. Chinese invention patent CN201110498 discloses a lighting device, which specifically belongs to a lamp panel illuminated by LEDs, including a lamp panel shell and a lampshade. The grille is composed of parabolic reflectors arranged symmetrically up and down and left and right to form a grid. The reflectors in the grid are arranged between the reflectors and the reflectors to form an independent reflection chamber with a large surface and a small arc-shaped trapezoid. Each independent reflection chamber There are LED lights at the bottom. The patent only reveals how to maximize the efficiency of LEDs to save power consumption, and a...
