Abstract
The utility model relates to the technical field of LED floodlights and discloses an LED panel light. The LED panel light comprises an outer shell body, an LED light, a light guide plate and a reflector. The LED light is closely arranged on the first side of the light guide plate, the second side of the light guide plate is arranged on the inner side of the outer shell body, the reflector is installed above the light guide plate, an elastic structure is arranged between the second side of the light guide plate and the inner side of the outer shell body, and elastic deformation of the elastic structure is within the range of thermal expansion and chilling shrink of the light guide plate. When the light guide plate deforms, the deformation amount of the light guide plate is absorbed by the elastic structure, tight fit between the luminous surface of the LED light and the light guide plate is not affected, in addition, the elastic structure is formed by the reflector self, and cost is reduced.
Description
Technical field
The utility model relates to LED illuminating lamp technical field, particularly a kind of LED flat lamp.
Background technology
LED is the abbreviation of English light emitting diode (light emitting diode); its basic structure is an electroluminescent semi-conducting material; place on the leaded shelf; use epoxy sealing then; play the effect of protection internal core, so the anti-seismic performance of LED is good.
The LED lamp is more and more higher in the occupation rate of lighting field, and the LED flat lamp is compared with other lamp decoration, and advantage is very outstanding, and it is ultra-thin, superbright, super energy-conservation, extra long life, environmental protection.The LED flat lamp is equipped with LGP by the LED lamp usually and wraps to make in the shell again, and LGP advances to guide into area source with the light that the LED lamp sends, and this just need will fit tightly between LED lamp and the LGP, and LGP also will be fixed on the lamp outer casing.But when temperature changed, LGP produced and expands or contraction, made the applying between LED lamp and the LGP produce deviation.At this situation, during design LED flat lamp, some gaps are reserved in the thermal expansion that is necessary for LGP, but this gap is influenced by ambient temperature, and is wayward, if the gap is stayed too smallly, then do not reach the effect of correction of deviation, too much if the gap is stayed, then influence the luminous efficiency of light fixture.
The utility model content
The purpose of this utility model is in order to solve the problems of the technologies described above, a kind of LED flat lamp to be provided, in the hope of correcting because the deviation of expanding with heat and contract with cold and causing of LGP by elastic construction.
The technical scheme that the utility model is taked is:
A kind of LED flat lamp, comprise shell body, LED lamp, LGP and reflecting piece, described LED lamp is near first side that is arranged on LGP, second side of described LGP is arranged on the inboard of described shell body, described reflector is installed in the top of described LGP, it is characterized in that between the inboard of second side of described LGP and described shell body elastic construction is set, the strain of described elastic construction is in the scope of expanding with heat and contract with cold of described LGP.
Further, the PET material of described reflecting piece.
Further, an end of close described LGP second side of described reflecting piece extends and bending to an end of described LGP second side, and described elastic construction is formed by described reflecting piece bending.
The beneficial effects of the utility model are:
1, LGP is when distortion, and its deflection is absorbed by elastic construction, does not influence fitting tightly between LED lamp light-emitting area and the LGP;
2, moderate flexible elastic construction can not weigh the LED lamp wounded;
3, form elastic construction by reflecting piece self, reduce cost.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Mark in the accompanying drawing is respectively:
1. shell body; 2.LED lamp;
3. LGP; 4. elastic construction;
5. reflecting piece; 6. blooming piece.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model LED flat lamp.
Referring to accompanying drawing 1, the LED flat lamp comprises shell body 1, LED lamp 2, LGP 3, first side and the LED lamp 2 of LGP 3 fit tightly, and second side of LGP 3 is arranged on the inboard of shell body 1, between second side of LGP 3 and the inboard of shell body 1 elastic construction 4 are set.Also be provided with reflecting piece 5 on LGP 3, reflecting piece 5 covers the top of LGP 3, and reflecting piece 5 is made by the PET material, has certain elasticity.One end of second side of reflecting piece 5 close LGPs 3 extends and bending formation elastic construction 4 to an end of LGP 3 second sides, and elastic construction 4 is in the shape of the letter V or the W font, and the amount of expanding with heat and contract with cold of its elastic range and LGP 3 is suitable.Below LGP 3, also be provided with blooming piece 6, be used for light carried out processing such as soft, dispersion.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (3)
1. LED flat lamp, comprise shell body, LED lamp, LGP and reflecting piece, described LED lamp is near first side that is arranged on LGP, second side of described LGP is arranged on the inboard of described shell body, described reflecting piece is installed in the top of described LGP, it is characterized in that: between the inboard of second side of described LGP and described shell body elastic construction is set, the strain of described elastic construction is in the scope of expanding with heat and contract with cold of described LGP.
