Description
Technical field
The invention belongs to the electric lighting technical field, be specifically related to a kind of high-powered LED lamp heat radiation lampshade.
Background technology
LED light source is the novel energy-conserving light source, generally power is called high-power LED light source greater than the LED light source of 80W, at present, the exploitation of high-power LED light source is gradually ripe with application, has wide market prospects, but, utilize the high-powered LED lamp that high-power LED light source is made to produce more heat transfer in luminescence process, if heat can not in time shed, can affect the work of components and parts, reduce the operating efficiency of light fixture, reduce its service life.
High-powered LED lamp on the existing market mainly radiating fin on lamp socket or lampshade dispels the heat, but its volume is larger, and radiating effect is not satisfactory, causes high-powered LED lamp to be heated yielding and aging.In addition, high-powered LED lamp also has the lower problem of light extraction efficiency.
Summary of the invention
The invention provides a kind of high-powered LED lamp heat radiation lampshade, simple and compact for structure, volume is little, and is lightweight, good heat dissipation effect, and light extraction efficiency is high.
For achieving the above object, the technical solution used in the present invention is: a kind of high-powered LED lamp heat radiation lampshade, comprise long square plate shape aluminium alloy body, fixed L ED light source on this aluminium alloy body, the side of the corresponding LED light source of aluminium alloy body is provided with some radiating subassemblies, has the gap between adjacent radiating subassembly;
Described each radiating subassembly comprises some aluminum alloy heat sinks fixing on strip plate shape aluminium alloy heat-radiating substrate and this aluminium alloy heat-radiating substrate, has the gap between adjacent aluminum alloy heat sink.
Further, the aluminium alloy heat-radiating substrate of described radiating subassembly is fixed on the aluminium alloy body through screw.
Further, 5～10 millimeters of the thickness ranges of described aluminium alloy heat-radiating substrate, 2～5 millimeters of the thickness ranges of described aluminum alloy heat sink.
Further, described aluminium alloy body, aluminium alloy heat-radiating substrate and aluminum alloy heat sink all have reflective top layer.
Characteristics of the present invention are: the aluminium alloy body of long square plate shape, the aluminium alloy heat-radiating substrate of strip plate shape and aluminum alloy heat sink all have radiating effect, area of dissipation is large, and good heat dissipation effect effectively promotes LED electric power module heat dissipation, and simple and compact for structure, volume is little; Aluminum alloy material has that thermal conductivity is good, thermal resistance is high, rapid heat dissipation, lightweight, price is lower (than materials such as copper), the characteristics of good weatherability (than materials such as PC), and good heat dissipation effect can reduce manufacturing cost, long service life.Have the gap between adjacent radiating subassembly, also have the gap between adjacent aluminum alloy heat sink, make air form circulation, strengthen radiating effect, make high-powered LED lamp be difficult for aging distortion, effectively extend its service life.
