Abstract

The utility model relates to a lighting facility, a high -power LED lamps and lanterns of alclad technique are moulded in adoption specifically says so. The casing of making including engineering plastics, the casing is by the bottom plate of rectangle and encircles the rectangle box body structure that constitutes jointly at bottom plate curb plate all around, and the outer surface distribution of casing has a fin, be provided with inside bellied rectangle boss on the bottom plate of casing, be provided with the aluminium foil layer on the inner wall of the bottom plate of casing and the curb plate of two relative settings. These lamps and lanterns are rational in infrastructure, the radiating effect good, production simple process, effectively reduce manufacturing cost on compromising heat dispersion's basis.

Description

A kind of using the high-power LED light fixture moulding alclad technology

Technical field

This utility model is related to a kind of luminaire, specifically a kind of using the high-power LED light fixture moulding alclad technology.

Background technology

High-power LED light fixture caloric value is big, but carries relative complex circuit structure because it is internal, is not suitable for using logical The mode of wind radiating.The LED lamp shell heat dispersion that common plasticses are made is bad；Conduction-type radiating using all-metal construction Not only complex manufacturing, also can increase substantially production cost.

Content of the invention

The purpose of this utility model is to provide a kind of rational in infrastructure, good heat dissipation effect, simple production process, low cost of manufacture Using the high-power LED light fixture moulding alclad technology.

For achieving the above object, this utility model employs the following technical solutions:

Described in the utility model a kind of using the high-power LED light fixture moulding alclad technology, make including engineering plastics Housing, described housing is by the base plate of rectangle and to be looped around the rectangular box structure that the side plate of base plate surrounding collectively forms, housing Outer surface fin is distributed with, the base plate of described housing is provided with inwardly protruded rectangular boss, the base plate of housing and two It is provided with aluminium foil layer on the inwall of the individual side plate being oppositely arranged.

It is provided with inwall and be provided with hinge on two outer walls of side plate side plate being oppositely arranged of aluminium foil layer, described hinge On support is installed.

Cylinder that is inwardly protruding and running through aluminium foil layer is arranged on the base plate of described housing, the top of described cylinder is threaded Installing hole.

After technique scheme, this fitting structure is reasonable, good heat dissipation effect, simple production process, is taking into account radiating Effectively reduce manufacturing cost on the basis of performance.

Brief description

Fig. 1 is the cross section structure diagram of one embodiment of this utility model.

Fig. 2 is the cross section structure diagram of Fig. 1 embodiment other direction.

Specific embodiment

The utility model will be further described with reference to the accompanying drawings and detailed description.

As shown in Figure 1 and Figure 2, described in the utility model a kind of using the high-power LED light fixture moulding alclad technology, including work The housing 1 that engineering plastics are made, described housing 1 is by the base plate of rectangle and to be looped around the square that the side plate 5 of base plate surrounding collectively forms Shape box body structure, side plate has four, and one group is oppositely arranged four sides constituting rectangular box two-by-two, and the outer surface of housing 1 divides It is furnished with fin 2, this fin 2 branch, in the outer surface of base plate and side plate, can increase surface area, improves radiating efficiency.Described shell Inwardly protruded rectangular boss 4, the inwall of the base plate of housing 1 and two side plates being oppositely arranged are provided with the base plate of body 1 On be provided with aluminium foil layer 3.

It is provided with inwall and be provided with hinge 6 on two outer walls of side plate side plate 5 being oppositely arranged of aluminium foil layer 3, described Support 7 is provided with hinge 6.

Cylinder 8,9 that is inwardly protruding and running through aluminium foil layer 3, the top of described cylinder 8,9 are arranged on the base plate of described housing 1 It is threaded installing hole, for installing led circuit board.

The advantage of this light fixture is as follows:

Heat-conducting area is big: inside adopts punching press aluminium sheet and pc engineering plastics combination, as the radiating of led luminous source Device.By increasing the contact area of led luminous source and punching press aluminium sheet, heat produced by led luminous source can effectively be transmitted To in radiator.

Secondth, heat dissipation path is short: the shell that internal punching press aluminium sheet and pc engineering plastics do, and is closely connect by process for pressing Touch, substantially reduce led luminous source to radiator, then the distance distributing to air.Heat transfer during led luminous source normal work Path greatly shortens, and is conducive to the transmission of heat energy.

Heatsink weight is light, and materials are few., actually used 1060 type aluminium alloy weight are 180g, pc taking 50w radiator as a example Engineering plastics 320g.And tradition 50w heatsink weight, typically in 800-1000g, greatly reduces the consumption of metal aluminium, reduce Radiator cost.

Good insulation preformance, the test of light fixture safety is easily passed through.Due to using plastic wraps punching aluminum component mode, lamp outer casing is Engineering plastics, whole lamp insulating properties are greatly improved.Using this technology, rated voltage 220v light fixture, the insulation of whole lamp Pressure numerical value reaches 5000v, considerably beyond national standard.And non-isolated power supply can be adapted to, power supply cost can compare isolation When reduce by more than 50%.
