The utility model is at above-mentioned deficiency, and the utility model provides a kind of high-power LED ceiling lamp.
To achieve these goals, technical solution adopted in the utility model is: a kind of high-power LED ceiling lamp, mainly comprise great power LED, radiator, great power LED is fixed on spreader surface, lamp panel central authorities are provided with a groove, be provided with perforate in the groove, lamp panel is fixed on the radiator, and great power LED protrudes in lamp panel; Great power LED is positioned at the closed cavity of lampshade and lamp panel formation, and radiator is arranged in the cavity of the groove of lamp panel, and the radiator top plan is isolated mutually above lamp panel and above-mentioned two cavitys;
Described radiator closely contacts with the lamp panel groove;
Also comprise fixed support, described fixed support is higher than the top plan of radiator;
Described groove bore size greater than or corresponding to the great power LED size;
Described radiator adopts a plurality of radiator fins to be formed by stacking, and becomes radial.
The beneficial effects of the utility model: radiator is positioned at the lamp panel groove, can effectively utilize whole lamp space.Radiator exposes in outside air, can improve to greatest extent and the contacting of air, and improves thermal radiation capability.The radiator top plan is higher than lamp panel, can make full use of the cross-ventilation of horizontal direction, improves radiating efficiency; Fixed support is higher than the top plan of radiator, forms certain the air gap between the ceiling in the house of this lamp affixed to the ceiling of installing and the radiator, makes radiator form cross-ventilation, quick heat radiating up and down.
In the confined space that great power LED lamp panel and lampshade etc. are formed, isolate mutually, be independent of each other, and confined space has the favorable protection ability, can prevent that dust, insect etc. from entering lamp body, improve the light extraction efficiency of light source with radiator portion.

The specific embodiment
As shown in Figure 2, the utility model embodiment outward appearance is a roudnel shape, and the outward appearance part is made up of lampshade 6, lamp panel 4, radiator 1 and lampshade fixture 7.The light fixture outward appearance depends primarily on two parts such as lampshade 6, lamp panel 4, constituting different shapes, as adopts square lampshade and lamp panel, and constituting overall appearance is square lamp affixed to the ceiling.Therefore, the outward appearance of this example can design according to different needs and adjust.
Lampshade 6 can be plastics or glass material making such as acrylic, PC, and the surface forms transparent, translucent or frosted shape, to adapt to different bright dippings and illumination needs.
Fig. 3 is the bottom view of the utility model embodiment.In the drawings, we can see that radiator 1 is positioned at lamp panel groove 41 centers of lamp panel 4, and radiator 1 is formed by numerous radiator fins 11 mutual superposition, are undertaken fasteningly by screw, make radiator 1 conglobate radial structure.The material of radiator fin 11 is that highly heat-conductive materials such as copper, aluminum metal, alloy are made, and structure can adopt same material one-body molded, also can use different materials to be formed by connecting.As can adopting metallic copper or other alloy materials to make in the center of radiator fin 11, can adopt efficient and light weight heat sink materials such as aluminium alloy in the edge of radiator fin 11, to alleviate the overall weight of radiator.
Lampshade fixture 7 is used to connect lampshade 6 and lamp panel 4, makes it to fuse, and is generally more than three, forms stable syndeton.The quantity of lampshade fixture 7 can be adjusted according to the weight or the shape of lampshade 6, is connected with the firm of lamp panel 4 to guarantee lampshade 6.In connection procedure, also can adopt general general mode to connect, as screw, bayonet socket or the like.
As Fig. 4 is the generalized section of this example.In the drawings, great power LED 2 is fixed on the surface, center of radiator 1, and this center surface is closely stack formation of radiator fin 11, and by series of processes such as polishings, makes center surface smooth smooth, is convenient to the installation of great power LED 2.
Adopt screw to fix in this example,, increase contact area, accelerate capacity of heat transmission so that the center surface of great power LED 2 and radiator 1 closely contacts.In the process of fixed L ED2, can apply the very thin Heat Conduction Materials such as heat-conducting glue of one deck at two contact-making surfaces, to fill contact gap, reduce thermal resistance.
In the drawings, we can see that lamp panel 4 is fixed on the installed surface of great power LED 2, and great power LED 2 and radiator 1 are positioned at different spaces.Great power LED 2 is positioned at the confined space of lampshade 6 and lamp panel 4 formations, can effectively prevent entering of dust, keeps the clean and tidy of interior volume environment, improves the light extraction efficiency of light fixture.Radiator 1 is positioned at the central authorities of lamp panel, and radiator 1 closely is connected with lamp panel 4, and lamp panel 4 is made for the metal or alloy material, can play the effect of auxiliary heat dissipation.Because radiator 1 and great power LED are separately in two different spaces, so both are independent of each other, can take into account the barrier propterty of light source and the heat dispersion of radiator 1 simultaneously.
As shown in Figure 5, be the three-dimensional exploded view of present embodiment.In the drawings, radiator 1 is to form one by first screw 12 in conjunction with setting-up piece 13 by radiator fin 11.High-power LED light source 2 is fastened on radiator 1 central authorities by second screw 22, dispels the heat by radiator 1, to reduce the DIE Temperature of LED.
Fixed support 3 is " U " font structure of a side direction, on each face, be respectively arranged with three apertures, first screw 31, second screw 32, the 3rd screw 33, wherein 31 pairs of first screws are fixed on by screw in the pad hole 131 of setting-up piece 13, are fixed on the radiator 1.Second screw 32 is fixed on lamp panel 4 on the fixed support 3 by screw corresponding to lamp panel 4.The 3rd screw 33 by screw, is fixed on light fixture on the ceiling.The height of fixed support 4 will be higher than the top plan of radiator, makes the certain space of formation between radiator 1 and the ceiling, is convenient to the heat loss through convection up and down of air.
Lampshade 6 is fixed on the lamp panel 4, and both are provided with packing ring 5 in the middle of connecting, and make lampshade 6 can form sealing, be connected closely with lamp panel 4, prevents that dust etc. from entering in the lampshade.
Above embodiment is a preferred version of the present utility model, but is not limited to above scheme.The simple change of any format surface and structure is all in the protection domain of this patent.
