Abstract
The utility model discloses a high-power LED ceiling lamp which comprises a torsional spring (1), light emitting units (2) and a mounting frame (3). The torsional spring (1) is arranged on the mounting frame (3), the number of the light emitting units (2) is multiple, the light emitting units (2) are evenly distributed on the mounting frame (3) and are connected with independent power supplies respectively, each light emitting unit (2) comprises a base plate (5) and a lamp body (9), one or more LED lamps (6) are arranged on the front face of each base plate (5), heat radiating columns (4) are arranged at the positions, matched with the LED lamps (6), of the back face of each base plate (5), and the base plates (5), the LED lamps (6), light guide plates (7) and light diffuser plates (8) are arranged in the lamp bodies (9) in sequence. The phenomenon that temperature is accumulated in the center point of a lamp panel is eliminated, a user can increase light strength according to needs, and dazzle light is effectively eliminated.
Description
Technical field
The utility model relates to a kind of large power LED ceiling lamp.
Background technology
Along with expanding economy, people no longer just for the demand of light, have increased more requirement, such as attractive in appearance, energy-conservation and environmental protection etc. for the requirement of light fixture.Current light source science and technology is constantly progressive, is also using various light sources light fixture in life, and particularly LED lighting engineering reaches its maturity, and the application of LED lighting engineering in life is more and more extensive.LED light fixture has the advantages such as volume is little, energy-saving and environmental protection, high brightness.
LED Ceiling light is a kind of being embedded in ceiling, and the lighting of penetrating under light is widely used in hotel, western-style restaurant, coffee shop and the illumination of market lamp.But because LED light source can send a large amount of heats, if the heat of generation can not be shed, will cause greatly reduce the service life of LED light source, and LED light source can not keep good working order, so the LED lamp power using can not be too high.When a little less than the luminous intensity of LED light source, user can not increase light intensity as required, and 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 the large power LED ceiling lamp that a kind of thermal diffusivity is good, have multi-illuminating unit is provided, and user can increase light intensity as required; Being used in conjunction with of LGP and light diffusing sheet can be eliminated light fixture and be dazzled light.
The purpose of this utility model is achieved through the following technical solutions: a kind of large power LED ceiling lamp, it comprises torsion spring, luminescence unit and installing rack, torsion spring is arranged on installing rack, the quantity of luminescence unit is a plurality of and is evenly distributed on installing rack, a plurality of luminescence units connect respectively independent power supply, luminescence unit comprises substrate and lamp body, the front of substrate is provided with one or more LED lamps, the back side of substrate is provided with thermal column with the position that LED lamp matches, the bright dipping side of LED lamp is disposed with LGP and light diffusing sheet, substrate, LED lamp, LGP and light diffusing sheet are arranged in lamp body successively.
A plurality of luminescence unit described in the utility model connects respectively independent power supply.
The central authorities of substrate described in the utility model arrange a LED lamp, and all the other LED lamps are distributed in the edge of substrate.
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, guaranteed the independence of each LED lamp heat radiation, the Position Design of while LED lamp, further strengthened radiating effect, lamp plate central point temperature accumulation phenomena has effectively been eliminated in the combination of two kinds of modes; A plurality of luminescence units are set, and each luminescence unit is controlled separately, and user can increase light intensity as required; Due to the use of LGP and light diffusing sheet, effectively eliminated and dazzled light.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model luminescence unit structural representation;
In figure, 1-torsion spring, 2-luminescence unit, 3-installing rack, 4-thermal column, 5-substrate, 6-LED lamp, 7-LGP, 8-light diffusing sheet, 9-lamp body.
