Abstract
The utility model discloses a high-efficiency LED lamp which comprises a light guide plate, a first reflection piece arranged above the light guide plate and LED lamp light sources evenly distributed in the peripheral direction of the lateral side of the light guide plate. Each LED light source comprises a first light emitting face facing the lateral side of the light guide plate and a second light emitting face opposite to the back side of the light guide plate. The lamp further comprises a second reflection piece facing the second light emitting face. The light guide plate can absorb light emitted from the LED lamp light sources to enable the light to stay on the surface of the light guide plate. When the light reaches tot all light guide points, reflected light can be diffused to all angles to be emitted from the front side of the light guide plate by breaking the reflection conditions. By means of the various light guide points in different densities and sizes, the light guide plate can emit light evenly. Light coming out form the top surface can be reflected to the light guide plate by the first reflection piece, light coming out from the lateral side can be reflected to the light guide plate by the second reflection piece, and accordingly the light using efficiency is improved. Furthermore, the brightness of the LED lamp can be improved.
Description
Technical field
The utility model relates to a kind of LED lamp field.
Background technology
Light-Emitting Diode (be called for short LED) be a kind of can be the solid-state semiconductor device of visible light with electric energy conversion, it is to utilize semiconductor wafer as luminescent material, when two ends added forward voltage, carrier in semiconductor occurred compoundly to cause photo emissions and produce light.
Yet because LED emergent light scope is large, the luminous energy that the unit optical extend has is compared low with conventional light source, directly adopts the LED illumination in most of the cases to be difficult to meet the needs of lighting and device.
In view of this, the utility model is studied for above-mentioned defect of the prior art, and the generation of this case is arranged then.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of LED light fixture of high brightness.
For addressing the above problem, the utility model provides a kind of efficient LED light fixture, comprise LGP, and the first reflector plate that is arranged on described LGP top, it is characterized in that, also comprise along described LGP side circumferentially uniform LED lamp source, described LED lamp source comprise first light-emitting area relative with described LGP side and with opposing the second light-emitting area in described LGP side, described light fixture also comprises second reflector plate relative with described the second light-emitting area.
As further improvement of the utility model, described LED lamp source is CCFL.
As further improvement of the utility model, described the second reflector plate is circular arc.
, as further improvement of the utility model, also comprise that is used for the fixed head that all described LED lamp source are fixing.
As further improvement of the utility model, described LGP below also arranges diffusion sheet.
As further improvement of the utility model, described diffusion sheet be two and between also be provided with prismatic lens.
The beneficial effects of the utility model are, the light that utilizes LGP to draw to send from the LED lamp source is in the stop on LGP surface, and when light was mapped to each light guiding points, reverberation can, toward all angles diffusion, then destroy conditioned reflex and penetrate by LGP is positive., by various densitys, light guiding points not of uniform size, can make the LGP uniformly light-emitting.And the first reflector plate exposes end face and reflexes on LGP, and the light reflection that the second reflector plate exposes side to LGP, is used for improving the service efficiency of light, and then improves the brightness of LED light fixture.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: the 2-LED lamp source; 4-the first reflector plate; The 6-LGP; 8-the second reflector plate.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1, the utility model comprises LGP 6, be arranged on the first reflector plate 4 of LGP 6 tops, and along LGP 6 sides circumferential uniform LED lamp source 2, LED lamp source 2 comprise first light-emitting area relative with LGP 6 sides and with opposing the second light-emitting area in LGP 6 sides, light fixture also comprises second reflector plate 8 relative with the second light-emitting area.The light that utilizes LGP 6 to draw to send from LED lamp source 2 is in the stop on LGP 6 surfaces, and when light was mapped to each light guiding points, reverberation can, toward all angles diffusion, then destroy conditioned reflex and penetrate by LGP 6 is positive., by various densitys, light guiding points not of uniform size, can make LGP 6 uniformly light-emittings.And the first reflector plate 4 exposes end face and reflexes on LGP 6, and the light reflection that the second reflector plate 8 exposes side to LGP 6, is used for improving the service efficiency of light.Further improve the brightness of LED light fixture.
Further, LED lamp source 2 is CCFL, and not only color is abundant and pure, and has the advantages such as high brightness, high lumen, energy-efficient, long distance vision better effects if.
Further, the second reflector plate 8 is circular arc, the side light that expose can be reflexed on LGP 6 more, improves the service efficiency of light.
Further, also comprise that one is used for the fixed head that all LED lamp source 2 is fixing, is used for supporting LED lamp source 2.
Further, LGP 6 belows also arrange diffusion sheet, are used for that light is carried out homogenising and process.
Further, diffusion sheet be two and between also be provided with prismatic lens because after light self-diffusion plate penetrated, the non-constant of its directive property, revised direction of light by prismatic lens, reaches the effect of optically focused, improves positive brightness.
Above-described embodiment is the better embodiment of the utility model; but embodiment of the present utility model is not limited by the examples; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify the substitute mode that all should be equivalence, within being included in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
