Description
Technical field
The present invention relates to a kind of light fixture, particularly LED shadowless lamp.
Background technology
Existing LED (LightEmittingDiode, light emitting diode) light fixture and light source, be mostly spot light, and easily produce dazzling dazzle, watch for a long time, fatiguability even causes visual impairment.Chinese invention patent CN201110498 discloses a kind of lighting device, specifically belong to a kind of lamp panel of LED illumination, comprise lamp panel shell and lampshade, lampshade uses aluminium sheet to be processed into the overall reflective grid in 16 or 25 square chambeies, this reflective gratings is by forming grid with the reflecting plate of the parabolically shape be symmetrical set up and down, be arranged to the trapezoidal independent reflection room of the little arcuation in the large end, face between reflecting plate in grid-like and reflecting plate, bottom each independently reflection room, be provided with LED.This patent just discloses the effect how maximally utilising LED and obtains saving power consumption, and the lighting effect of similar conventional grates is reached by matrix arrangement, although adopt each LED to set up the purpose of design of independently reflection room to be reduce LED dazzle, but the essence solution reducing LED dazzle is not provided, the implementation method of area source is not described yet.
Chinese invention patent discloses CN101273231B lamp box, possesses distributing board, be arranged in the multiple point source of lights on above-mentioned distributing board, be configured in the light reflecting board around above-mentioned point source of light, and the light diffusing surface plate of the light transmission relatively to configure with above-mentioned light reflecting board, above-mentioned light reflecting board have surround above-mentioned multiple point source of light each and be formed as being inverted multiple accommodation recesses of polygonal cone-shaped, above-mentioned point source of light is inserted into respectively in the inserting hole being formed at above-mentioned accommodation concave bottom, and the top of above-mentioned multiple accommodation recess is connected with the top of accommodation recess adjacent separately, the top of above-mentioned accommodation recess is positioned at below the point of bisection from the illuminating part of above-mentioned point source of light to the distance of above-mentioned light diffusing surface plate and more than the illuminating part of above-mentioned point source of light position.Multiple point source of lights on distributing board LED light line intersect less than formation shadow region, position, thus LED light can not be made to intersect mixing equably, still can produce dazzle.
Above-mentioned LED light can not produce intersection, there is following large shortcoming: 1) during work, can see LED particle, dazzling; 2) can not accomplish without shadow, light shield occur obvious blackening; 3) light efficiency rate is not high, lower than 60lm/W.
Summary of the invention
The present invention is intended to solve the above-mentioned defect of prior art, provide a kind of not dazzling, without the LED shadowless lamp of shadow and specular removal rate.
The technical solution adopted in the present invention is: LED shadowless lamp, comprises lamp panel 1, diffuser plate 2 and LED light source 3, and lamp panel 1 opening is closed by diffuser plate 2; The light that two horizontal adjacent LED light sources 3 send is formed and intersects, and the light that two longitudinal adjacent LED light sources 3 send is formed and intersects; Described diffuser plate 2 is positioned between 1 times of two adjacent LED light source (3) fore-and-aft distances and twice position
The light angle that described LED light source 3 sends is α.
Lateral separation between described two horizontal adjacent LED light sources 3 is A, and the distance of the ray intersection position that two horizontal adjacent LED light sources 3 send and LED light source 3 is then
Fore-and-aft distance between described two longitudinal adjacent LED light sources 3 is B, and the distance of the ray intersection position that two longitudinal adjacent LED light sources 3 send and LED light source 3 is then
Described diffuser plate 2 is between H1 and H2.
Described LED light source 3 is matrix arrangement bottom lamp panel 1.
The matrix of described LED light source 3 bottom lamp panel 1 is arranged as square or rectangular.
Compared with prior art, between the light crossover location that the light crossover location sent at two horizontal adjacent LED light sources 3 by diffuser plate 2 due to the present invention and two longitudinal adjacent LED light sources 3 are sent, such setting emits after making LED light source 3 form intersection again, make adjacent LED light source 3 can not form shade at diffuser plate 2, there is the uniform light emitted, reach the advantage of the effect without shadow; LED light source 3 particle is can't see during work, not dazzling; Light efficiency rate significantly improves, and light efficiency rate is higher than advantages such as 60lm/W.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figure 1: LED shadowless lamp, comprise lamp panel 1, diffuser plate 2 and LED light source 3, lamp panel 1 opening is closed by diffuser plate 2; LED light source 3 is matrix arrangement bottom lamp panel 1, and as shown in Figure 2, the matrix of LED light source 3 is arranged in square, and as shown in Figure 3, the matrix of LED light source 3 is arranged in rectangle; Lateral separation between two horizontal adjacent LED light sources 3 is A, and the fore-and-aft distance between two longitudinal adjacent LED light sources 3 is B.
Shown in composition graphs 4, Fig. 5, the light that two horizontal adjacent LED light sources 3 send is formed and intersects, and the light that two longitudinal adjacent LED light sources 3 send is formed and intersects; Described diffuser plate 2 is positioned between 1 times of two adjacent LED light source (3) fore-and-aft distance B and twice position, namely between 1B and 2B, emit again after making LED light source 3 form intersection by this distance setting of diffuser plate, make adjacent LED light source 3 can not form shade at diffuser plate 2, there is the uniform light emitted, reach the advantage of the effect without shadow; LED light source 3 particle is can't see during work, not dazzling; Light efficiency rate significantly improves, and light efficiency rate is higher than advantages such as 60lm/W.
The light angle that LED light source 3 sends is α, and the lateral separation between two horizontal adjacent LED light sources 3 is A, and the distance of the ray intersection position that two horizontal adjacent LED light sources 3 send and LED light source 3 is then
fore-and-aft distance between two longitudinal adjacent LED light sources 3 is B, and the distance of the ray intersection position that two longitudinal adjacent LED light sources 3 send and LED light source 3 is then
Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Its embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
