Abstract
The invention discloses a high-efficiency LED lamp. The high-efficiency LED lamp comprises a light guide plate, a first reflecting piece which is arranged above the light guide plate and LED light sources which are evenly distributed along the side face of the light guide plate in the circumferential direction. Each LED light source comprises a first luminous face which is opposite to the side face of the light guide plate and a second luminous face which is away from the side face of the light guide plate. The lamp further comprises second reflecting pieces which are opposite to the second luminous faces. The light guide plate is used for absorbing light emitted from the LED light sources, the light is reserved on the surface of the light guide plate, when light is emitted to each light guide pot, the reflected light can be diffused towards all angles, and a reflecting condition is damaged and the reflected light is given out from the right side of the light guide plate, and through the guide light pots with various densities and sizes, the light guide plate is made to give out light evenly. Therefore, light shown from the top face of a first reflecting piece is reflected to the light guide plate through the first reflecting piece, and light shown from the side faces of the second reflecting pieces is reflected to the light guide plate through the second reflecting pieces. The high-efficiency LED lamp is used for improving using efficiency of light, and furthermore brightness of the LED lamp is improved.
Description
Technical field
The present invention relates to a kind of LED lamp field.
Background technology
Light-Emitting Diode (being called for short LED) is a kind of solid-state semiconductor device that electric energy can be converted into visible light, it is to utilize semiconductor wafer as luminescent material, when two ends added forward voltage, carrier in the semiconductor took place compoundly to cause photo emissions and produce light.
Yet because LED emergent light scope is big, 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 satisfy the needs of lighting and device.
In view of this, the present invention is directed to above-mentioned defective of the prior art and study, the generation of this case is arranged then.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of LED light fixture of high brightness.
For addressing the above problem, the invention provides a kind of efficient LED light fixture, comprise LGP, and 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 second light-emitting area in described LGP side, described light fixture also comprises second reflector plate relative with described second light-emitting area.
As a further improvement on the present invention, described LED lamp source is CCFL.
As a further improvement on the present invention, described second reflector plate is circular arc.
As a further improvement on the present invention, comprise that also is used for the fixed head that all described LED lamp source are fixing.
As a further improvement on the present invention, below the described LGP diffusion sheet is set also.
As a further improvement on the present invention, described diffusion sheet be two and between also be provided with prismatic lens.
Beneficial effect of the present invention is, 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 leaded light point, reverberation can destroy conditioned reflex by the positive ejaculation of LGP then toward all angles diffusion.By various densitys, leaded light point not of uniform size, can make the LGP uniformly light-emitting.And first reflector plate exposes end face and reflexes on the LGP, and the light that second reflector plate exposes the side reflexes on the 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 invention.
Wherein: the 2-LED lamp source; 4-first reflector plate; The 6-LGP; 8-second reflector plate.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further details.
As shown in Figure 1, the present invention includes LGP 6, be arranged on 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 second light-emitting area in LGP 6 sides, light fixture also comprises second reflector plate 8 relative with 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 leaded light point, reverberation can destroy conditioned reflex by LGP 6 positive ejaculations then toward all angles diffusion.By various densitys, leaded light point not of uniform size, can make LGP 6 uniformly light-emittings.And first reflector plate 4 exposes end face and reflexes on the LGP 6, and the light that second reflector plate 8 exposes the side reflexes on the 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 advantages such as high brightness, high lumen, energy-efficient, long distance vision better effects if.
Further, second reflector plate 8 is circular arc, the side light that expose can be reflexed on the LGP 6 more, improves the service efficiency of light.
Further, also comprise one for the fixed head that all LED lamp source 2 are fixed, be 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 handle.
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 was revised direction of light by prismatic lens, reaches the effect of optically focused, improves positive brightness.
Above-described embodiment is preferred implementation of the present invention; but embodiments of the present invention are not limited by the examples; other any do not deviate from change, the modification done under spiritual essence of the present invention and the principle, substitutes, combination, simplify the substitute mode that all should be equivalence, is included within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
