Abstract
The utility model discloses a high-efficiency cooling structure of an LED lamp. The high-efficiency cooling structure comprises an LED chip and a cooling frame which is fixed below the LED chip in an attaching mode, wherein the cooling frame comprises a cross-shaped framework, and cooling fins which are diffused outwards with the end portion of the framework serving as a center are arranged on the end portion of the framework. Heat is dissipated by the cooling frame which is attached to the LED chip, the heat produced by the LED chip can be transferred quickly and effectively, accumulation of a large amount of heat is prevented, and the normal usage of the LED lamp is guaranteed; the cooling frame is provided with the cooling fins, so that the contact area of the cooling frame and the air is increased, the heat can be transferred through heat conduction quickly, and the cooling efficiency is improved; and the cooling frame is in an integrated cross-shaped framework structure, can be used for cooling of a plurality of LED lamp beads simultaneously and is convenient to install and fix, and the structure inside a lamp body is simplified.
Description
Technical field
The utility model relates to a kind of radiator structure of LED lamp.
Background technology
The LED lamp is as a kind of emerging semiconductor light-emitting elements, because it is little to have volume, low-power consumption, light quality height, simple in structure, life-span is long, plurality of advantages such as anti-seismic performance is good, and color category is abundant, and bright lamp response speed is fast, be widely used in occasions such as Landscape Lighting, large screen display, and will have entered the domestic lighting field on a large scale.
Because single led lamp pearl power is little, generally a plurality of LED lamp pearls are combined as a luminescence unit with series connection or mode in parallel as lighting bulb, but a plurality of LED lamp pearls can produce more heat energy, add that led chip is very thin, this heat energy can produce huge side effect to LED lamp pearl, if can not efficiently radiates heat, the luminous efficiency of LED lamp pearl can reduce thereupon, influenced its service life, under the critical conditions, can cause LED lamp pearl to be lost efficacy at once, so one of the bottleneck that heat radiation is large-power LED light bead uses and obstacle.
Heat radiation seems even more important for the special light fixture of some outdoor uses, if heat is constantly assembled at led chip, distributes and does not go out, and can form high temperature, in special places such as mine, underpass, and may be explosion caused when serious.
The utility model content
In order to overcome the high-powered LED lamp heat dispersion deficiency of prior art, service life is short, shortcoming that may be accidents caused, and the utility model provides a kind of LED lamp high-efficiency heat radiation structure.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of LED lamp high-efficiency heat radiation structure comprises led chip, fits to be fixed on the heat radiation rack of led chip below, and described heat radiation rack comprises the skeleton that is cross-shaped cross, and the end of described skeleton is provided with the radiating fin of outwards dispersing centered by this end.
In order to improve radiating effect, described radiating fin end is provided with the U-shaped bifurcated.
For the ease of the location is installed, the circumferentia that described U-shaped furcated end is linked to be is the square structure at four Edge Blend angles.
For the maximum radiating effect that improves, the four LED lamp pearls that led chip comprises aluminium base and is arranged on the aluminium base top, fit in the lower surface of described heat radiation rack upper surface and aluminium base, and four end points correspondences of skeleton are arranged on four LED lamp pearls below.
Further, described heat radiation rack is connected with reflection shield, thereby led chip is fixed between heat radiation rack and the reflection shield.
In order to improve radiating effect, described led chip and heat radiation rack are by the heat-conducting glue bonding connection.
The beneficial effects of the utility model are: dispel the heat by the heat radiation rack with the led chip applying, can prevent a large amount of heat accumulations fast and effectively with the transfer of heat that produces on the led chip, guaranteed the normal use of LED lamp; Heat radiation rack is provided with radiating fin, has increased the contact area of heat radiation rack and air, makes heat to move away by the heat conduction fast, has improved radiating efficiency; Heat radiation rack adopts cross-shaped integral type skeleton structure, and the heat radiation of corresponding a plurality of LED lamp pearls simultaneously installs and fixes conveniently, has simplified the structure of lamp body inside.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structure broken away view of the present utility model;
Fig. 2 is the structure broken away view of another angle of the utility model;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is the structural representation of another angle of the utility model.
The specific embodiment
Referring to figs. 1 through Fig. 4, a kind of LED lamp high-efficiency heat radiation structure of the present utility model, comprise led chip 1, applying is fixed on the heat radiation rack 3 of led chip 1 below, described heat radiation rack 3 comprises the skeleton 31 that is cross-shaped cross, and the end of described skeleton 31 is provided with the radiating fin of outwards dispersing 32 centered by this end.Be the radiating fin 32 that each end outward radial of described skeleton 31 is extended with divergent shape, radiating fin 32 is circumferentially arranged along the end of skeleton 31.
In order to improve radiating effect, described radiating fin 32 ends are provided with U-shaped bifurcated 321.
For the ease of the location is installed, the circumferentia that described U-shaped bifurcated 321 ends are linked to be is the square structure at four Edge Blend angles.The cube structure at the four Edge Blend angles that described heat radiation rack 3 is combined to form for the upper and lower end face of the circumferentia that is linked to be by U-shaped bifurcated 321 ends and heat radiation rack 3.Like this, only some stopper slots need be set in lamp body inside, just can carry out support fixation to heat radiation rack 3.
In order farthest to improve radiating effect, led chip 1 comprises aluminium base 12 and is arranged on four LED lamp pearls 11 on the aluminium base 12, fit in the lower surface of described heat radiation rack 3 upper surfaces and aluminium base 12, four end points correspondences of skeleton 31 are arranged on four LED lamp pearls, 11 belows.
Further, described heat radiation rack 3 is connected with reflection shield 4, and the LED lamp pearl 11 on the led chip 1 penetrates in the through hole of reflection shield 4, thereby led chip 1 is fixed between heat radiation rack 3 and the reflection shield 4.
In order to improve radiating effect, described led chip 1 passes through the heat-conducting glue bonding connection with heat radiation rack 3.The aluminium base 12 of led chip 1 is born the function of fixed L ED lamp pearl 11, cloth circuits and heat conduction.
Certainly, the utility model can also have other structural distortion except above-mentioned embodiment, and these equivalent technical solutions also should be within its protection domain.
