Abstract
A kind of without packaged LED backlight lens, these backlight lens comprise exiting surface, side step face, bottom surface, and side step face connection exiting surface above and bottom surface below, be provided with an incidence hole in the central authorities of bottom surface; This bottom surface is reflective cambered surface, and is wherein sheet cube without packaging LED chips, end face and four sides simultaneously luminous, by the reflection of bottom surface, incidence hole, exiting surface with reflect even bright dipping.Five luminescences of LED chip in the utility model, end face bright dipping is by diffusion after incidence hole refraction, uniformly hot spot is reflected further through exiting surface, four, LED chip side light-emitting area reflects through exiting surface through incidence hole refraction rear portion, and another part reflexes to exiting surface through reflective cambered surface and reflects lens forming uniform light spots again.
Description
[technical field]
The utility model relates to technical field of LED illumination, particularly relates to the improvement of LED-backlit lens.
[background technology]
This product backlight lens are used for coupling without packaged LED lamp pearl, and what is called refers to a kind of novel LED lamp bead without packaged LED, and this LED lamp bead does not need to encapsulate gold thread.
In current backlight technology, the backlight for LCDs does thinner and thinner, needs constantly improvement opportunity how when keeping brightness constant, to realize LCD backlight evenly luminous effect.
[summary of the invention]
The utility model for above problem propose a kind of have employed the reflective cambered surface combination of exiting surface, incidence hole and bottom backlight lens, these backlight lens can provide the luminosity of the backlight lens twice relative to existing routine, lamp bar number required for can reducing, and the brightening piece that can cut conventional lenses also can reduce the integral thickness of the product applying backlight lens.
The one that relates to described in the utility model is without packaged LED backlight lens, and these backlight lens comprise exiting surface, side step face, bottom surface, and side step face connection exiting surface above and bottom surface below, be provided with an incidence hole in the central authorities of bottom surface; It is characterized in that, this bottom surface is reflective cambered surface, and is wherein sheet cube without packaging LED chips, end face and four sides simultaneously luminous, by the reflection of bottom surface, incidence hole, exiting surface with reflect even bright dipping.
The reflective cambered surface cambered surface concentric on incidence hole of this bottom surface, is applicable to being reflected into the light that the LED chip in unthreaded hole sends.
The reflective cambered surface of this bottom surface is annular cambered surface, is from minor diameter to major diameter toward the cambered surface that lens interior turns down.
Five luminescences of LED chip in the utility model, end face bright dipping is by diffusion after incidence hole refraction, uniformly hot spot is reflected further through exiting surface, four, LED chip side light-emitting area reflects through exiting surface through incidence hole refraction rear portion, and another part reflexes to exiting surface through reflective cambered surface and reflects lens forming uniform light spots again.

Fig. 2 is the light path schematic diagram of the utility model without packaged LED backlight lens;
Wherein: 10, exiting surface; 20, side step face; 30, bottom surface; 31, incidence hole; 40, LED chip.
[detailed description of the invention]
Below in conjunction with drawings and Examples, the utility model is described in detail.
The one that relates to described in the utility model is without packaged LED backlight lens, these backlight lens comprise exiting surface 10, side step face 20, bottom surface 30, side step face 20 connects exiting surface 10 above and bottom surface 30 below, an incidence hole 31 is provided with in the central authorities of bottom surface 30, it is characterized in that, this bottom surface 30 is reflective cambered surface, and is wherein sheet cube without packaging LED chips 40, end face and four sides are simultaneously luminous, by the reflection of bottom surface, incidence hole, exiting surface with reflect even bright dipping.
The reflective cambered surface cambered surface concentric on incidence hole 31 of this bottom surface, is applicable to being reflected into the light that the LED chip 40 in unthreaded hole sends.
The reflective cambered surface of this bottom surface 30 is annular cambered surface, is from minor diameter to major diameter toward the cambered surface that lens interior turns down.
Please refer to accompanying drawing 2: be arranged in the incidence hole of backlight lens without packaging LED chips, be five luminescences without packaging LED chips, rising angle can reach more than 180 degree, and the rising angle 180 degree of traditional backlight lens all can not reach.Lens coupling be five luminous without packaged LED, at the light sent of lens bottom design reflective circular rotating cambered surface process LED chip four sides.End face bright dipping is by diffusion after incidence hole refraction, uniformly hot spot is reflected further through exiting surface, four, LED chip side light-emitting area reflects through exiting surface through incidence hole refraction rear portion, and another part reflexes to exiting surface through reflective cambered surface and reflects lens forming uniform light spots again.
Five luminescences of LED chip in the utility model, end face bright dipping is by diffusion after incidence hole refraction, uniformly hot spot is reflected further through exiting surface, four, LED chip side light-emitting area reflects through exiting surface through incidence hole refraction rear portion, and another part reflexes to exiting surface through reflective cambered surface and reflects lens forming uniform light spots again.
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.
