Abstract
A kind of square focus spot backlight lens, these backlight lens comprise lens body, this lens body comprises upper surface and bottom surface, at the upper surface of these lens, there is non-circular exiting surface, this lens exiting surface be projected in the hyperbola that bottom surface is four sections of round and smooth linkings, and exiting surface is compound curved surface, at each section of hyperbola, lens are divided into a hyperbola unit, then on each hyperbola elemental area, form first surface and the second curved surface, the first surface of all hyperbola unit and the compound curved surface of the second Surface forming lens exiting surface.The lens of this compound curved surface make light form square focus spot through exiting surface, can realize hot spot even transition in quite short distance, effectively avoid the dark space formed at lamp pearl midline position, improve uniformity and the efficiency of backlight.If this backlight application on a television set, the most effectively can reduce the lamp pearl on LCD TV backlight lamp bar, reduce backlight module cost and reduce LCD TV thickness simultaneously.
Description
[technical field]
The utility model relates to technical field of LED illumination, particularly relates to LED light source lens.
[background technology]
The utility model relates to backlight lens, requires uniform in light emission as backlight lens, and the hot spot even transition between the lamp pearl of periphery.There is the problem that bright dipping is uneven, light emission rate is low in current backlight lens diagonal positions.
[summary of the invention]
The utility model proposes square focus spot backlight lens for above problem, and this lens uniform in light emission, the transition of lamp pearl are soft, and light extraction efficiency is high.
Described in the utility modelly relate to square focus spot backlight lens, these backlight lens comprise lens body, this lens body comprises upper surface and bottom surface, at the upper surface of these lens, there is non-circular exiting surface, this lens exiting surface be projected in the hyperbola that bottom surface is four sections of round and smooth linkings, and exiting surface is compound curved surface, at each section of hyperbola, lens are divided into a hyperbola unit, then on each hyperbola elemental area, form two integrated first surfaces and the second curved surface, the first surface of all hyperbola unit and the compound curved surface of all hyp second Surface forming lens exiting surfaces.
Be connected between position at upper surface and bottom surface and be provided with periphery sides, at bottom surface, central authorities are provided with light source mounting hole, are that symmetrical centre is provided with location suspension column in periphery sides with light source mounting hole.
This first surface is greater than the projected area width of light source mounting hole at bottom surface at the projected area width of bottom surface.
The lens of the compound curved surface that the utility model adopts make light form square focus spot through exiting surface, can realize hot spot even transition in quite short distance, effectively avoid the dark space formed at lamp pearl midline position, improve uniformity and the efficiency of backlight.If this backlight application on a television set, the most effectively can reduce the lamp pearl on LCD TV backlight lamp bar, reduce backlight module cost and reduce LCD TV thickness simultaneously.

Wherein: 10, lens body; 11, upper surface; 12, bottom surface; 121, light source mounting hole; 13, periphery sides; 14, locating dowel; 15, hyperbola unit; A, first surface; B, the second curved surface.
[detailed description of the invention]
Below in conjunction with drawings and Examples, the utility model square focus spot backlight lens are described in detail.
Please refer to accompanying drawing 1: illustrated therein is this square focus spot backlight lens, these backlight lens comprise lens body 10, this lens body 10 comprises upper surface 11 and bottom surface 12, these backlight lens comprise lens body, this lens body comprises upper surface 11 and bottom surface 12, at the upper surface of these lens, there is non-circular exiting surface, this lens exiting surface be projected in the hyperbola that bottom surface is four sections of round and smooth linkings, and exiting surface is compound curved surface, at each section of hyperbola, lens are divided into a hyperbola unit 15, then on each hyperbola unit 15, form two integrated first surface A and the second curved surface B, the first surface A of all hyperbola unit 15 and all hyp second curved surface B forms the compound curved surface of lens exiting surface.
Wherein by light, evenly this is between lens center line to first surface A, the position between the second curved surface B then plays light uniform refraction to lens.After two kinds of curved surfaces combine, the uniform square focus spot of the light reflected of lens can be obtained, the perfect evenly combination of the hot spot between lamp pearl can be made.
Be connected between position at upper surface 11 and bottom surface 12 and be provided with periphery sides 13, be provided with light source mounting hole 121 in bottom surface central authorities, with light source mounting hole 121 for symmetrical centre is provided with location suspension column 14 in periphery sides 13.
This first surface A is greater than the projected area width of light source mounting hole at bottom surface at the projected area width of bottom surface.
The lens of this compound curved surface make light form square focus spot through exiting surface, and hot spot even transition can be realized in quite short distance, relative to conventional backlit lens, effectively avoid the dark space formed at lamp pearl midline position, improve uniformity and the efficiency of backlight.If this backlight application on a television set, the most effectively can reduce the lamp pearl on LCD TV backlight lamp bar, reduce backlight module cost and reduce LCD TV thickness simultaneously.
The above, it is only the utility model preferred embodiment, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when utilizing the technology contents of above-mentioned announcement or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solutions of the utility model content, any simple modification that above embodiment is done is referred to according to the utility model technology, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
