The device provided by the invention can increase the heat transmitting and dissipating area and can generate all-around air convection, thus ensuring safe temperature for lamps.
Description
Technical field
The present invention relates to normal lighting and pass the heat dissipation technology field, refer in particular to a kind of by the temperature difference between each stacked heat-sink unit body, the big radiating surface that the rule twist and warping of each radiator structure form, and the heat-conducting medium between each substrate just matches, increase area of dissipation, realize the heat efficient biography heat abstractor of conduction fast.
Background technology
Characteristics such as at present, the LED light fixture is as a kind of green light source, and is pollution-free because of it has energy savings, long service life and more and more be subjected to social extensive use.But, have only 10%～40% electric energy to convert luminous energy in the LED course of work, remaining electric energy nearly all converts heat energy to, the temperature of LED is raise, and the service life of LED and radiating effect is closely related, if the heat that light source produces can not in time be drained, continuous high temperature can have a strong impact on the service life of LED light fixture and reduce the output of light, and temperature is too high, and light decay is serious, the light efficiency utilization rate is low, the lost of life.Along with the application of great power LED, heat dissipation problem is outstanding all the more; If do not add cooling measure, then the wick temperature of great power LED can rise rapidly, and when its junction temperature rises above maximum allowable temperature (generally being 150 ℃), great power LED can damage because of overheated; As seen, common radiator can't satisfy the radiating requirements of big heat.
Summary of the invention
For addressing the above problem, it is simple to the invention provides a kind of lamp body structure, and omnibearing cross-ventilation can be derived heat more quickly, guarantees the safe temperature of light fixture, avoids light decay, guarantees the efficient biography heat abstractor in the normal service life of light fixture.
For achieving the above object, the present invention adopts following technical scheme to be: this biography heat abstractor comprises some heat-sink unit bodies, described heat-sink unit body is connected by substrate, these substrate two ends are extended with radiator structure, this radiator structure is twisted and warped in the middle part of substrate and is centrosymmetric, and this radiator structure is formed by some radiating fin parallel arrangements.
The anglec of rotation of the radiator structure between described heat-sink unit body is 5～10 °, and respectively the twist and warping angle of the radiating fin of this radiator structure is 20 °～40 °.
The thickness of described heat-sink unit body is consistent, and length, the width of the radiating fin of this heat-sink unit body are consistent.
The thickness of described heat-sink unit body is 0.6～1mm, and the length of the radiating fin of this heat-sink unit body is 60mm, and its width is 10～15mm.
Connect in punching press riveted joint mode between described heat-sink unit body, respectively the joint face between the substrate of this heat-sink unit body scribbles the heat-conducting medium material.
The quantity of described heat-sink unit body is 16.
The quantity of the radiating fin of described radiator structure is 30.
The bottom center of the substrate of tool maximum area is provided with light source in the described heat-sink unit body.
Beneficial effect of the present invention is: the multilayer stack design of heat-sink unit body, cooperate the parallel arrangement design of radiating fin in radiator structure twist and warping design and the radiator structure, guarantee that it can increase vent passages in multilayer riveted joint back, the every interlayer of radiator structure is the different angles rotation, make the integral body that passes heat abstractor be semi-circular, radiating fin is uniformly distributed in sphere, pass area of dissipation to increase, omnibearing cross-ventilation, in addition, scribble the heat-conducting medium material between substrate and the substrate, make thermal source just can not transmit fast to lower level, guarantee the safe temperature of light fixture by higher level; The bottom surface that is used to be provided with light source is an open space, helps the flexible design reflector, and this big plane also helps the design that the water proof and dust proof of product is handled.
