Abstract
The utility model discloses a light-emitting diode (LED) lamp. The LED lamp comprises an LED light source, an upper cover and a control element, and further comprises a heat dissipation shell. The cross section of the heat dissipation shell is shaped like an H, and the upper portion of the heat dissipation shell is connected with the upper cover. The upper surface of a separating plate in the middle is connected with the LED light source, and the control element is arranged in a cavity in the lower portion of the separating plate. By utilizing a heat dissipation structure shaped like an H, heat can be guided to two sides through the separating plate in the middle of the H, the surface of a lamp shell is arranged on the two sides, the heat can be dissipated quickly by utilizing convection of air, and therefore the technical problems that a heat dissipation structure of a lamp is complex in structure, auxiliary heat dissipation devices around the lamp are multiple, and a heat dissipation effect is poor can be solved.
Description
Technical field
The utility model relates to lighting field, specifically, relates to a kind of LED light fixture.
Background technology
The LED light fixture also claims led lamp, Par lamp, with its technical characterstic such as efficient, energy-conservation, long-lived, small and exquisite, is becoming main force's product of illumination market of new generation, and is effectively spurring the high speed development of environmental protection and energy-conservation industry.Under the background that Present Global energy starved worry raises once again, energy savings is the important problem that we shall face future, at lighting field, the application of LED luminous product is just attracting common people's sight, LED is as a kind of novel green light source product, must be the trend of future development, 21st century be the novel illumination light source epoch take LED as representative.LED be called as the 4th generation lighting source or green light source, have the characteristics such as energy-saving and environmental protection, the life-span is long, volume is little, can be widely used in the fields such as various indications, demonstration, decoration, backlight, general lighting and urban landscape.
The shortcoming of LED maximum is generated heat greatly exactly, and solve heat radiation could well use, and present solution has two kinds on the market: a kind of is that great majority adopt 6 pairs of led light sources 1 of fan to cool off, as shown in Figure 1, and be that noise is large with the shortcoming of fan 6, the life-span is short, problem that volume is large etc.; Another kind is because the shortcoming fan of fan dispels the heat and use large heat radiation aluminium instead, partly is connected (control element is installed in the control section) with independent control again, and the shortcoming of this scheme is that volume is large, complex structure, Heavy Weight.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, the LED light fixture that radiating effect is good.
In order to solve the problems of the technologies described above, the utility model provides a kind of LED light fixture, comprise led light source, loam cake and control element, also include heat-dissipating casing, the cross section of described heat-dissipating casing is the H type, top connects loam cake, and the upper surface of intermediate membrane is connected with led light source, in the lower partition cavity control element is installed.
Further, the outer surface of described heat-dissipating casing is provided with a plurality of radiating fins.
Further, described led light source is the LED luminous plaque that light emitting diode and wiring board form.
Further, described loam cake is the aluminium loam cake.
Further, described heat-dissipating casing is the aluminium heat-dissipating casing.
The utility model utilizes H type radiator structure, make heat lead both sides by the dividing plate in the middle of the H, and both sides are exactly the surface of lamp outer casing, the convection current of universal air, heat sheds fast, lamp cooling structure is complicated, peripheral auxiliary heat dissipation equipment is many thereby solve, and the bad technical problem of radiating effect.Add control element and be installed in the interior unique design of H type heat-dissipating casing lower cavity, do not need to connect separately again control section, alleviated the weight of LED light fixture, reduced the volume of light fixture.
Description of drawings
Fig. 1 is a kind of existing LED light fixture cutaway view.
Fig. 2 is LED light fixture cutaway view of the present utility model.
Fig. 3 is LED light fixture three-dimensional cutaway view of the present utility model.
Wherein: 1, led light source; 2, loam cake; 3, heat-dissipating casing; 31, dividing plate; 4, fin; 5, control element; 6, fan.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and being implemented, but illustrated embodiment is not as to restriction of the present utility model.
Such as Fig. 2 and shown in Figure 3, a kind of LED light fixture of the utility model, comprise led light source 1, loam cake 2, control element 5 and heat-dissipating casing 3, the cross section of heat-dissipating casing 3 is the H type, top connects loam cake 2, the upper surface of intermediate membrane 31 is connected with led light source 1, in dividing plate 31 lower cavity control element 5 is installed.Preferably, the outer surface of heat-dissipating casing 3 is provided with a plurality of radiating fins 4.Fin 4 can increase the area of dissipation of heat-dissipating casing 3, and can make extraneous air form convection current between fin 4, improves radiating effect.
Led light source 1 of the present utility model can be selected the general LED light-emitting component in this area, such as LED luminous plaque, LED wiring board etc.; Optimally, led light source is the LED luminous plaque that light emitting diode and wiring board form; Without doubt, also can adopt according to actual needs other universal or special led light source in the actual production.Further, for improving radiating effect, alleviate light fixture weight, loam cake 2 and heat-dissipating casing 3 all can adopt aluminium.
Advantage of the present utility model is that volume is little, and is lightweight, easy for installation, carries fast, greatly reduces the various costs of whole product.And the critical part that realizes these advantages namely is the solution of H type heat-dissipating casing, and it can extraordinaryly export to heat on the aluminium shell, and the aluminium shell has increased area of dissipation greatly by the design of a lot of fins, sheds fast by cross-ventilation again.Solve LED light fixture Heavy Weight, complexity has been installed, has carried inconvenience and the bad technical problem of radiating effect.In addition, because the control section element can be integrated in H type heat-dissipating casing inside, so that the light fixture whole height can significantly reduce, increased the attractive in appearance of light fixture, and reduced the light fixture volume.
The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and protection domain of the present utility model is not limited to this.Being equal to that those skilled in the art do on the utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
