Abstract

The utility model discloses an upright-type heat-dissipation structure with a plastic heat-dissipation lamp body for an LED lamp. In order to iron out the defects that a conventional LED lamp is high in cost of the heat-dissipation lamp body and is easy to cause personal injury because of electric leakage, and the plastic heat-dissipation lamp body is poor in heat-dissipation effect, the structure is based on the LED lamp and employs the heat-conduction plastic upright-type heat-dissipation lamp body. In other words, the plastic heat-dissipation lamp body of the LED lamp is reasonably provided with a plurality of upright-type heat dissipation columns. The center of each heat dissipation column is provided with a heat conduction metal which is a column-shaped heat conduction metal inlaid in the process of injection moulding. After the plastic upright-type heat-dissipation lamp body is manufactured, the surface of each column-shaped heat conduction metal is coated with a heat-conduction plastic layer, and the thickness of each heat-conduction plastic layer is less than 2 mm. The structure is in favor of improving the heat-dissipation effect of the energy-saving illuminating plastic heat-dissipation body of the LED lamp while the cost is reduced and the safety is improved.

Description

A kind of column radiator structure of LED light fixture plastic cement heat radiation body

Affiliated technical field

The utility model belongs to LED energy-saving lighting lamp manufacture technology field, is specifically related to a kind of column radiator structure of LED light fixture plastic cement heat radiation body.

Background technology

In LED energy-saving lighting lamp, radiating treatment is extremely important, current LED energy-saving lighting lamp uses aluminum or aluminum alloy as heat radiation body more, this lamp body excellent radiation performance, but complex process, cost is high, easily electric leakage causes personal injury, on market, also there is part heat conduction plastic cement heat radiation body, heat conduction plastic cement heat loss through radiation ability is strong, but thermal conductivity factor is low, add plastic cement heat radiation body profile irregular, lamp body surface distance thermal source has far to be had closely, heat can not conduct fast on heat conduction plastic cement, dispel the heat inhomogeneous, radiating effect must be waited to improve on the whole.Technical know-how of the present utility model basis is: when thermal source and radiator are in contact with one another, thermal source and spreader surface vertical range are at 5mm and when following, and the thermal conductivity factor of radiator is only greater than 5W/ (mK) and just the impact of temperature difference is leveled off to 0.

Heat conduction plastic cement thermal conductivity factor is in the market in 10W/ (mK) left and right, if continue to improve thermal conductivity factor, the metallic particles thing being added in plastic cement also needs to increase, and originally the insulation attribute of plastic cement will become conductor, and then affects the security of light fixture.But the thermal conductivity factor that heat conduction plastic cement is current and metal still have very big-difference [thermal conductivity factor of aluminium alloy is in 230W/ (mK) left and right], since heat conduction plastic cement is difficult to improve thermal conductivity factor under the prerequisite of insulation, we only shorten the distance on thermal source and lamp body surface in the time of design plastic cement heat radiation body so, namely by the good thermal conductivity of heat-conducting metal, the heat orientation fast light source being produced is transmitted to the position close to more from plastic cement heat radiation body surface, cause the low heat conductivity of heat conduction plastic cement can not become heat conducting serious obstruction, be convenient to the heat Quick uniform of lamp body inside to lamp body surface conductive.

Summary of the invention

For overcome existing LED energy-saving illumination heat radiation body complex process, high, the easy electric leakage of cost cause personal injury and plastic cement lamp body thermal conductivity factor poor, the bad deficiency that waits of radiating effect, the utility model provides a kind of column radiator structure of LED light fixture plastic cement heat radiation body, this structure can not only make up the deficiency of metal LED energy-saving illumination heat radiation body, and the thermal conductivity of increase plastic cement heat radiation body that can be even, directed, facilitate quick conduction and the heat radiation of heat.

The utility model solves the technical method that its technical problem adopts: on LED lighting, adopt column plastic cement heat radiation body, many root posts formula thermal column is namely reasonably set on the plastic cement heat radiation body of LED lamp light source substrate reverse side, in the middle of thermal column, it is heat-conducting metal, aluminium matter or the column heat-conducting metal (can be also graphite) copper or that irony heat conductivility is good that plastic cement heat radiation body is bumped in injection molding process, this heat-conducting metal can be multiple independently heat-conducting metal members, also can be an overall heat-conducting metal member, after column plastic cement heat radiation body completes, this column heat-conducting metal surface is wrapped one deck heat conduction plastic cement, heat conduction plastic cement thickness is less than 2 millimeters, be convenient to the heat of light source generation by the directed conduction of heat-conducting metal Quick uniform, to lamp body diffusion into the surface, reach the object of the better heat conduction and heat radiation effect of plastic cement heat radiation body.

The beneficial effects of the utility model are, can be simple in operation, on the basis of low cost, LED energy-saving illumination plastic cement heat radiation body that security performance is high, better improve the heat dispersion of plastic cement lamp body.
