Abstract
The utility model discloses a cooling structure of an LED (Light-Emitting Diode) lamp. The structure comprises an LED lamp bead, a metal substrate, a fuse and a cooling rack; the cooling rack comprises a vertical cooling ring; horizontal cooling fins are respectively arranged at the inner and the outer sides of the ring wall of the cooling ring; the horizontal stretching widths of the cooling fins are successively decreased from top to bottom so that a horn-shaped cooling opening is formed; a first refrigeration fin is arranged between the metal substrate and the fuse; and a second refrigeration fin is arranged between the fuse and the cooling rack. Through the cooling structure, the cooling effect of the LED lamp can effectively improved; the cooling area is effectively increased through the arrangement of the cooling ring and the cooling fins in the cooling rack, and heat is easy to discharge through the horn-shaped cooling opening formed among the cooling fins; and meanwhile, the first and the second refrigeration fins can effectively conduct produced heat into the cooling rack so that heat is dissipated by the cooling fins.
Description
Technical field
The utility model relates to a kind of LED lamp.
Background technology
The LED(light emitting diode) basic structure is an electroluminescent semi-conducting material, places on the leaded shelf, then uses epoxy sealing all around, plays the effect of protection internal core.Led light source have advantages of use low-tension supply, power consumption less, applicability is strong, stability is high, the response time is short, environmentally safe, multicolor luminous etc., although the existing illuminating equipment of price is expensive, will substitutes inevitably and have illuminating device now.The heat radiation of LED lamp is a large technical barrier at present, affects the service life of LED.
The utility model content
The purpose of this utility model is to provide a kind of LED lamp radiator structure of energy Effective Raise radiating effect.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
LED lamp radiator structure comprises LED lamp pearl, metal substrate, heat melting device and heat radiation rack, and it is characterized in that: heat radiation rack comprises the heat dissipating ring of vertical direction, and the inside and outside both sides of the ring wall of heat dissipating ring are equipped with the fin of horizontal direction.
Further, the horizontal-extending width of fin reduces from top to bottom successively, forms trumpet-shaped radiating opening.
Further, be provided with the first cooling piece between metal substrate and the heat melting device.
Preferably, the first cooling piece adopts semi-conducting material to make.
Further, be provided with the second cooling piece between heat melting device and the heat radiation rack.
Preferably, the second cooling piece adopts semi-conducting material to make.
The utility model has following beneficial effect owing to having adopted technique scheme:
Radiating effect that can Effective Raise LED lamp arranges heat dissipating ring and fin in heat radiation rack, effectively increased area of dissipation, forms simultaneously trumpet-shaped radiating opening between the fin, is conducive to heat and discharges; And the first cooling piece that arranges and the second cooling piece can effectively conduct to the heat that produces in the heat radiation rack, utilize fin to dispel the heat.The utility model is simple in structure, manufacturing is easy, cost is low, and is practical.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the schematic diagram of the utility model LED lamp radiator structure.
The specific embodiment
As shown in Figure 1, for the utility model LED lamp radiator structure, comprise LED lamp pearl 1, metal substrate 2, heat melting device 3 and heat radiation rack 4, be provided with the first cooling piece 5, the first cooling pieces 5 between metal substrate 2 and the heat melting device 3 and adopt semi-conducting material to make; Being provided with the second cooling piece 6, the second cooling pieces 6 between heat melting device 3 and the heat radiation rack 4 adopts semi-conducting material to make.Heat radiation rack 4 comprises the heat dissipating ring 7 of vertical direction, and the inside and outside both sides of the ring wall of heat dissipating ring 7 are equipped with the fin 8 of horizontal direction, and the horizontal-extending width of fin 8 reduces from top to bottom successively, forms trumpet-shaped radiating opening 9.The first cooling piece 5 and the second cooling piece 6 can effectively conduct to the heat that produces in the heat radiation rack 4, utilize fin 8 to dispel the heat, heat dissipating ring 7 and fin 8 are set in heat radiation rack 4, effectively increased area of dissipation, form simultaneously trumpet-shaped radiating opening 9 between the fin 8, be conducive to heat and discharge from this radiating opening 9, the radiating effect of Effective Raise LED lamp.
Only be specific embodiment of the utility model below, but technical characterictic of the present utility model is not limited to this.Any take the utility model as the basis, for realizing essentially identical technique effect, done the ground simple change, be equal to replacement or modification etc., all be covered by among the protection domain of the present utility model.
