Abstract

The utility model discloses an LED ceiling lamp with good heat dissipation performance. The LED ceiling lamp comprises a substrate (2) and a lamp body (6). The front surface of the substrate (2) is provided with one or more LED lights (3), and the positions on the back surface of the substrate (2) which correspond to the LED lights (3) are provided with heat dissipation columns (1); the light emitting side of the LED lights (3) is sequentially provided with a light guide plate (4) and a light diffuser plate (5); the substrate (2), the LED lights (3), the light guide plates (4) and the light diffuser plate (5) are sequentially mounted inside the lamp body (6); the edge of the lamp body (6) is provided with a plurality of torsion springs (7). The heat dissipation columns are arranged separately and thereby guarantee the independency of heat dissipation of every LED light (3) and effectively eliminate the temperature accumulation in the center point of the light substrate; meanwhile, the light guide plate (4) and the light diffuser plate (5) effectively eliminate glare; the plurality of torsion springs (7) arranged on the edge of the lamp body (6) facilitate the installation of the LED ceiling lamp.

Description

The LED Ceiling light that a kind of thermal diffusivity is good
Technical field
The utility model relates to the LED Ceiling light that a kind of thermal diffusivity is good.
Background technology
LED Ceiling light is compared with traditional illuminating lamp, it has the advantages, the particularly efficient characteristics of luminescence of LED Ceiling light such as energy-saving and environmental protection, safety and long service life, has promoted the luminous efficiency of light fixture, therefore, LED Ceiling light is generally used to room lighting place.
Existing LED Ceiling light radiation aluminium adopts integral type, and high-powered LED lamp is welded on aluminium base board, and monoblock aluminium base board dispels the heat by the radiating equipment of one, and this radiator structure causes lamp plate central point temperature to be gathered; The light of dazzling of the light emitting source of existing LED Ceiling light is dealt with improperly simultaneously, and people's eyes feel under the weather, and long-time use also likely affects one's power of vision.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of LED Ceiling light that can effectively eliminate lamp plate central point temperature accumulation phenomena is provided, and being used in conjunction with of its LGP and light diffusing sheet, effectively eliminates light fixture and dazzle light.
The purpose of this utility model is achieved through the following technical solutions: the LED Ceiling light that a kind of thermal diffusivity is good, it comprises substrate and lamp body, the front of substrate is provided with one or more LED lamps, and the back side of substrate is provided with thermal column with the position that LED lamp matches.
The bright dipping side of LED lamp described in the utility model is disposed with LGP and light diffusing sheet, and substrate, LED lamp, LGP and light diffusing sheet are arranged in lamp body successively.
Lamp body described in the utility model edge is provided with a plurality of torsion springs.
The beneficial effects of the utility model are: the back side of substrate is provided with thermal column with the position that LED lamp matches, and have guaranteed the independence of each LED lamp heat radiation, have effectively eliminated lamp plate central point temperature accumulation phenomena; Due to the use of LGP and light diffusing sheet, effectively eliminated and dazzled light; Lamp body edge is provided with a plurality of torsion springs, is convenient to LED Ceiling light and is fixed on ceiling with embedded mounting means.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure, 1-thermal column, 2-substrate, 3-LED lamp, 4-LGP, 5-light diffusing sheet, 6-lamp body, 7-torsion spring.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, the LED Ceiling light that a kind of thermal diffusivity is good, it comprises substrate 2 and lamp body 6, the front of substrate 2 is provided with one or more LED lamps 3, the position of matching with LED lamp 3 in the back side of substrate 2 is provided with thermal column 1, this replaces with the single independent heat radiation of LED lamp 3 by original integrated radiating structure, has guaranteed the independence of each LED lamp 3 heat radiations.LED lamp 3 bright dipping sides are disposed with LGP 4 and light diffusing sheet 5, LGP 4 is used the PMMA sheet material of optical grade, LGP 4 surfaces are printed on density by screen printing technology, reflective spot not of uniform size, reflective spot can be converted into vertical light with irreflexive form by directional light and penetrate from LGP 4 is positive, and LGP 4 bright dippings are even, thermal column 1 scribbles reflective ink or posts reflective sheeting towards the one side of LGP 4, in LGP 4 exiting surface the place aheads, be provided with light diffusing sheet 5, light diffusing sheet 5 adopts light diffusion PC or PMMA material, the light penetrating from LGP 4 can be processed evenly again, make LED Ceiling light surface light emitting even, effectively eliminate and dazzle light, substrate 2, LED lamp 3, LGP 4 and light diffusing sheet 5 are arranged in lamp body 6, lamp body 6 edges are provided with a plurality of torsion springs 7, torsion spring 7 is for being fixed on ceiling by LED Ceiling light with embedded mounting means.

Claims (2)
