Detailed description of the invention
In order to solve the lower problem of prior art LED light line use ratio, the utility model proposes a kind of LED side luminescent panel lamp, by all having upside reflecting piece and the downside reflecting piece of reflective structure, the remaining light of LED being imported light guide plate, thus improves the utilization rate of LED light line.
Following examples are further described the utility model by reference to the accompanying drawings.
Shown in Figure 1, for the embodiment of a kind of LED side of the utility model luminescent panel lamp, comprise main frame 11, back shroud 14, light guide plate 2, diffuser plate 13 and LED3, main frame 11 extends internally out for the gripper shoe 12 of supporting diffusion plate 13, diffuser plate 13 is placed in gripper shoe 12, light guide plate 2 is placed on diffuser plate 13, back shroud 14 is fixed on the top of main frame 11, and filler 15 can be added between back shroud 14 and light guide plate 2 occur being shifted to avoid light guide plate 2, light guide plate 2 comprises printing opacity front 23, the light incident sides 22 that the reflective back side 21 and some rings are established, the reflective back side 21 is provided with reflective structure, printing opacity front 23 is translucent construction, LED3 is fixed on main frame 11, and LED3 is arranged at the side of light incident sides 22, guide-lighting gap 5 is left between LED3 and light incident sides 22.
Upside reflecting piece 41 and downside reflecting piece 42 is also provided with in the present embodiment, a part for upside reflecting piece 41 is located at the reflective back side 21, another part of upside reflecting piece 41 crosses over the upside in guide-lighting gap 5, and a part for downside reflecting piece 42 is located at printing opacity front 23, another part of downside reflecting piece 42 crosses over the downside in guide-lighting gap 5, upside reflecting piece 41 and downside reflecting piece 42 have reflective structure towards the side of light guide plate 2, so that the remaining light of LED3 is imported light guide plate 2.
Based on above-mentioned known, due to upside reflecting piece 41 and downside reflecting piece 42 in the present embodiment, the remaining light of LED3 will be fed to light guide plate 2, thus the light of LED3 is all imported to light guide plate 2, improve the utilization rate of LED3 light, namely be the light efficiency that improve light fixture under same power, or use power can be reduced under identical light efficiency.
Further, also carry out preferably, can continuing shown in Figure 1 to other structures in the present embodiment, specific as follows:
Upside reflecting piece 41 connects the reflecting piece edge of downside reflecting piece 42 away from printing opacity front 23 away from the reflecting piece edge at the reflective back side 21 by middle brace 43, only a reflecting piece edge of upside reflecting piece 41 is fixed on light guide plate 2, there is the problem being easy in reflecting piece 41 use procedure of upside rock, similarly only a reflecting piece edge of downside reflecting piece 42 is fixed on light guide plate 2, then also there is the problem being easy in reflecting piece 42 use procedure of downside rock, therefore, add middle brace 43 can avoid occurring that this rocks.
Upside reflecting piece 41 also comprises extends towards the direction away from LED3 the upside Extendible flake 411 being convenient to be fixedly connected with, and upside Extendible flake 411 is attached at the reflective back side 21, simply be sticked upside reflecting piece 41 can be fixed by upside Extendible flake 411, improve the fixed efficiency of upside reflecting piece 41.
Downside reflecting piece 42 also comprises extends downside Extendible flake 421 towards the direction away from LED3, and downside Extendible flake 421 is attached at printing opacity front 23, by downside Extendible flake 421 and be simply sticked, downside reflecting piece 42 can be fixed, effectively can improve the fixed efficiency of downside reflecting piece 42, further, printing opacity front 23 comprises and is positioned at zone line, and the light transparent area 231 that can penetrate away and be positioned at fringe region, the shading region 232 that can not penetrate and light is blocked, downside Extendible flake 421 covers shading region 232, now, first downside Extendible flake 421 is to fix downside Extendible flake 421 better, next the light reflection of directive shading region 232 can be returned light guide plate 2, improve the utilization rate of light, finally also because the light reflection of shading region 232 is got back to tabula rasa by downside Extendible flake 421, and shading region 232 is identical with gripper shoe 12 occlusion area, thus avoid the problem occurring dark side in shading region 232.
Upside reflecting piece 41, downside reflecting piece 42 and middle brace 43 can be integrated connection, be convenient to a producing shaped, be conducive to enhancing productivity, in addition, for the selection of material, only need to select side mask to have the material of reflective structure, and in the present embodiment, be the reflective sheeting having selected production technology comparatively ripe, select cost low.
As from the foregoing, adopt the present embodiment under the prerequisite not customizing specific lighting angle LED, cost that can be lower can improve the utilization rate of light.
In sum; major design of the present utility model is upside reflecting piece by all having reflective structure and downside reflecting piece; the remaining light of LED is imported light guide plate; avoid the problem that in prior art, LED light line use ratio is low; therefore; under the prerequisite not departing from the utility model principle; it will be understood by those skilled in the art that; can be improved according to the above description or be converted, do not made the improvement made under the prerequisite of creative work and conversion and all should belong to the protection domain of the utility model claims.
