Abstract
The utility model discloses a high-power LED square-box-shaped ceiling lamp, which comprises a square-box-shaped ceiling lamp body. The ceiling lamp body comprises a lower light-passing board, an upper metal dissipating board and a lateral square aluminum frame. A plurality of aluminum base circuit boards are arranged on the metal dissipating board. A plurality of high-power LED bulbs are arranged on the aluminum base circuit boards. The luminescent part of the LED bulb is positioned toward the light-passing board. The square aluminum frame is enclosed by four aluminum alloy extrusion section bars and the cross sections of the aluminum alloy extrusion section bars are trapezoidal. The inner sides of the aluminum alloy extrusion section bars are equipped with grooves and inclined aluminum boards and the light-passing board is clamped inside the grooves. Heat emitted by the LED bulbs is directly conducted to the plate-shaped aluminum alloy extrusion section bars and the square aluminum frame via the aluminum base circuit boards and then the heat is quickly radiated to the air via the plate-shaped aluminum alloy extrusion section bars and the square aluminum frame. Therefore, the heat radiation of the LED bulbs is accelerated and the operating temperature of the LED bulbs is effectively lowered. The service life of the bulbs is prolonged. Since no special radiator is adopted by the ceiling lamp, the weight of the entire lamp is reduced.
Description
Technical field
The utility model relates to a kind of lighting device, is specifically related to the great power LED square box shape ceiling light of a kind of single led lamp pearl power greater than 0.3W.
Background technology
Traditional ceiling light of box-shaped in many ways as light source, because fluorescent tube itself structure and the characteristic that are had, makes the ceiling light of the type exist that power consumption is big, lack service life and the defective of not environmental protection with fluorescent tube.Be directed to this; People gradually adopt the LED lamp replacing traditional ceiling light, and existing LED ceiling light uses LED lamp pearl to replace fluorescent tube on the basis of traditional ceiling light and simplifies the lamp bracket of traditional ceiling light and constitute, than traditional ceiling light; It has plurality of advantages such as low energy consumption, high light efficiency, long service life, environmental protection; But also exist following defective: adopt the heat that large-power LED light bead produced bigger,, cause the operating temperature in the body too high easily in case heat can't distribute fast effectively and be accumulated in the fluorescent tube; And then influence service life of LED fluorescent tube; And the part ceiling light is equipped with large-scale radiator in order to quicken heat radiation on ceiling light, causes the weight of whole lamp body big, security performance is not high.
Summary of the invention
The utility model problem to be solved is, to the deficiency of above-mentioned technology, the design people design a kind of simple in structure, weight is little, thermal diffusivity good, the uniform great power LED square box shape of illumination ceiling light.
The utility model is that the technical scheme that its problem of solution is adopted is:
A kind of great power LED square box shape ceiling light; Comprise square box shape ceiling light main body; Said ceiling light main body comprises light-passing board, the metallic heat radiating plate of top and the square aluminum frame of side of below, and some aluminium base circuit boards are installed on the metallic heat radiating plate, and several large-power LED light beads are housed on the aluminium base circuit board; The illuminating part of LED lamp pearl is towards light-passing board; Said square aluminum frame is trapezoidal aluminum alloy extrusion section bar by four cross sections and surrounds, and the aluminium sheet of side groove and inclination is arranged in the aluminum alloy extrusion section bar, and light-passing board is stuck in the groove.
In the utility model, said metallic heat radiating plate is to be combined into by some tabular aluminum alloy extrusion section bars side by side.
In the utility model, there is draw-in groove the inboard of said tabular aluminum alloy extrusion section bar, and aluminium base circuit board is contained in the draw-in groove the inside, and the opening of draw-in groove is towards light-passing board.
In the utility model, on the said tabular aluminum alloy extrusion section bar radiation rib is arranged.
In the utility model, the inboard aluminium sheet of said aluminum alloy extrusion section bar is arc line type.
The beneficial effect of the utility model is: aluminium sheet reflection, the scattering process of tilt in the inner surface of the tabular aluminum alloy extrusion section bar of the light that LED lamp pearl sends in the utility model through constituting metallic heat radiating plate and the square aluminum frame, make light soft, be evenly distributed in whole lighting space, further; Aluminium base circuit board is contained in the draw-in groove the inside; Not only more attractive in appearance, also increased the reflective surface area of ceiling light body inner surface, further; LED lamp pearl is contained on the circuit through pacifying aluminium base circuit board; The heat that LED lamp pearl comes out is directly transferred on tabular aluminum alloy extrusion section bar and the square aluminum frame through aluminium base circuit board, and tabular aluminum alloy extrusion section bar and square aluminum frame promptly diffuse to heat in the air and go, and has not only accelerated the heat radiation of LED lamp pearl; Reduced operating temperature effectively; Increase the service life of lamp pearl, also reduced special-purpose radiator, reduced the weight of whole ceiling light.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structural representation of present embodiment;
Fig. 2 is A-A direction cutaway view of Fig. 1;
Fig. 3 is the B part enlarged drawing of Fig. 2.
The specific embodiment
Referring to figs. 1 through Fig. 3; The utility model provide a kind of simple in structure, weight is little, thermal diffusivity good, the uniform high-power square box shape ceiling light of illumination; Comprise square box shape ceiling light main body, the metallic heat radiating plate 3 that the light-passing board 2, top that said ceiling light main body comprises the below is combined into by some tabular aluminum alloy extrusion section bars 31 side by side and the square aluminum frame 1 of side, the inboard of said tabular aluminum alloy extrusion section bar 31 has two clamp bar slots 32; Article two, aluminium base circuit board 4 is contained in draw-in groove 32 the insides respectively; The opening of draw-in groove 32 is equipped with three large-power LED light beads 5 towards light-passing board 2 on the aluminium base circuit board 4, the illuminating part of LED lamp pearl 5 is towards light-passing board 2; Because draw-in groove 32 can cover aluminium base circuit board 4 unnecessary parts, so seem neat appearance.Said square aluminum frame 1 is surrounded by four similar trapezoidal aluminum alloy extrusion section bars 6 in cross section, and side groove 61 and the aluminium sheet 62 that tilts are arranged in the aluminum alloy extrusion section bar 6, and light-passing board 2 is stuck in the groove 61, and metallic heat radiating plate 3 closely is fixedly mounted on the square aluminum frame 1.
As preferred embodiment, aluminum alloy extrusion section bar 6 inboard aluminium sheets 62 are the arc line type with certain radian, not only increase the area of reflection, also make its profile more attractive in appearance.In order to save the space, the constant-current supply 7 of supplying power for large-power LED light bead 5 is installed in the square aluminum frame 1.For the efficient of accelerating to dispel the heat, the radiation rib 33 that strengthens heat radiation is arranged on the tabular aluminum alloy extrusion section bar 31, heat can be dispersed in the air apace go.
