Abstract
The utility model provides a luminous even LED lamp, includes luminescent line board (1), a plurality of LED light source and sets up optical lens (2) on each LED light source, the cross -section of the bottom of every optical lens (2) is the wave and forms a plurality of refracting surfaces (20), the central authorities of optical lens (2) bottom have appearance chamber (21), each LED light source with regard to the holding in corresponding appearance chamber (21), the top center of every optical lens (2) has pit (22). The utility model discloses a LED lamp can produce parallel, the even effect of shining to form the illuminating effect of a brightness uniformity, soft, free from glare, avoided pointolite ubiquitous to concentrate the visual effect who shines away from central authorities, bill -board that the specially adapted plane is shone, uses such as the signpost of indicateing night, sign.
Description
Technical field
The utility model relates to LED technical field, is specifically related to a kind of luminous uniform LED.
Background technology
LED because having the features such as low-power consumption, light efficiency is high, the life-span is long, and becomes widely used light fixture in a kind of people's daily life.During use, LED can produce strong dazzle, easily stimulates the eyes of user.In order to improve the glare problem of LED, the structure of people to lamp body is improved.As the Chinese utility model patent " LED panel lamp " that notification number is CN203963550U (application number is 201420197713.7), LED panel lamp disclosed in it adopts the structure of light source board and light guide plate, light guide plate can carry out scattering process to the light that LED light source plate is launched, outwards penetrate again, thus form the light source of a face luminescence.But, only rely on the effect of light guide plate the light that LED lamp bead is launched cannot be scattered out fully, make the light luminance that irradiates from light guide plate inconsistent, still damage the eyes of user.
Utility model content
Technical problem to be solved in the utility model provides one to have parallel, uniform radiation response for above-mentioned prior art, and brightness of illumination is even, soft, the LED of free from glare.
The technical scheme in the invention for solving the above technical problem is: a kind of luminous uniform LED, comprise circuit board, be arranged in multiple LED light source on circuit board and multiple optical lens be arranged on each LED light source in the matrix form, it is characterized in that: the cross section undulate of the bottom of each optical lens and form multiple plane of refraction, central authorities bottom optical lens have one to the cavity volume be recessed on, and each LED light source is just contained in corresponding cavity volume;
Further, the center of top of each optical lens forms a pit to lower recess.
The bottom outer edge of each optical lens has the circle extension edge to downward-extension.
Selectively, the cross section bottom described optical lens is circular arc wave.
Selectively, the V-shaped wave in cross section bottom described optical lens.
Compared with prior art, the utility model has the advantage of: in the uniform LED of this luminescence, multiple planes of refraction that the pit at optical lens top coordinates the wavy cross-section design of bottom and formed, each LED light source is through the optical lens of particular design of the present invention, change the refraction angle of the LED light source emitted light being positioned at optical lens bottom center, make light straight line after the refraction of each plane of refraction overlapping, irradiation at short distance face presents directional light, can produce parallel, uniform radiation response, thus form a kind of brightness uniformity, soft, the illuminating effect of free from glare, avoid the ubiquitous visual effect of going out from central cover of spot light, be specially adapted to the billboard of planar illumination, the guideboard of instruction at night, the uses such as mark.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
Embodiment one:
As shown in FIG. 1 to 3, be the utility model good embodiment.The uniform LED of this luminescence, comprises circuit board 1, multiple LED light source (not shown in FIG.), multiple optical lens 2.
Wherein, multiple LED light source is arranged on circuit board 1 in the matrix form, each LED light source is covered with an optical lens 2.
In the present embodiment, optical lens 2 is overall rounded, and the bottom outer edge of each optical lens 2 has the circle extension edge 23 to downward-extension, thus LED light source can be located at wherein by this optical lens 2.
The cross section undulate of the bottom of each optical lens 2 and form multiple plane of refraction 20, the central authorities bottom optical lens 2 have one to the cavity volume 21 be recessed on, and each LED light source is just contained in corresponding cavity volume 21.
Further, the center of top of each optical lens 2 forms a pit 22 to lower recess.As shown in Figure 3, the cross section bottom optical lens 2 is circular arc wave, and also, plane of refraction 20 is in circular arc.
The pit 22 of the center of top of optical lens 2 is coordinated to make LED light source emitted light after superrefraction by this wavy multiple plane of refraction 20, irradiation at short distance face presents directional light, parallel, uniform radiation response can be produced, thus form the illuminating effect of a kind of brightness uniformity, soft, free from glare, avoid the ubiquitous visual effect of going out from central cover of spot light, and then realize the good radiation response of LED light source.
Embodiment two:
As shown in Figure 4, be the sectional view of optical lens in embodiment two, the distinctive points of this embodiment and embodiment one is only: the V-shaped wave in the cross section bottom optical lens 2, and also, plane of refraction 20 is in planar shaped.
Claims (4)
1. the uniform LED of luminescence, comprise circuit board (1), be arranged in multiple LED light source on circuit board (1) and multiple optical lens (2) be arranged on each LED light source in the matrix form, it is characterized in that: the cross section undulate of the bottom of each optical lens (2) and form multiple plane of refraction (20), the central authorities of optical lens (2) bottom have one to the cavity volume be recessed on (21), and each LED light source is just contained in corresponding cavity volume (21);
Further, the center of top of each optical lens (2) forms a pit (22) to lower recess.
