Abstract

The utility model discloses a heat dissipation shell of an LED tunnel lamp. The heat dissipation shell comprises an extension support, a left heat dissipation module, a right heat dissipation module and middle modules located between the left heat dissipation module and the right heat dissipation module, and the left heat dissipation module and the right heat dissipation module are arranged on the two sides of the support. The modules are fixedly arranged on the support through screws. General standard components are adopted as the components, LED tunnel lamps with different powers are matched by increasing the length of the support and the number of the middle modules, extension is convenient, and therefore production efficiency is improved, and cost is lowered. The heat dissipation shell is used for mounting and fixing the LED lamp and is meanwhile used for cooling the LED lamp, the size and the mass of the LED lamp are reduced, and meanwhile the heat loss of the lamp through convection is facilitated better through an exposed cooling mode.

Description

A kind of LED Tunnel Lamp heat-dissipating casing

Technical field

The utility model relates to LED heat sink for lamp, relates in particular to a kind of LED Tunnel Lamp heat-dissipating casing.

Background technology

LED is the abbreviation of English Light Emitting Diode, and light emitting diode, is a kind of semiconductor solid luminescence device.LED can be visible ray by electric energy conversion, and it has changed the principle that incandescent lamp tungsten filament is luminous and energy-saving fluorescent lamp tricolor powder is luminous, and adopts electroluminescence, has that luminous efficiency is high, a little power consumption, the high feature of simple, the luminous uniformity of control circuit.Along with the proposition of " energy-conservation " and " green illumination " theory, LED is incorporated in lighting gradually as light source.

At present, in prior art, high-powered LED lamp mostly needs the shell of an aluminium or other metal as the installation basis of LED heat abstractor, on a lamp, generally has the shell that is no less than 2 covers, manufactures described shell and mostly adopts die casting, workmanship of spraying plastics.These shells have in fact only played connection and decoration function, cost of manufacture is high, and manufacture craft is big for environment pollution, needs further to adjust shell sizes with coupling when LED lamp power changes greatly, housing itself is unfavorable for the heat radiation of LED lamp simultaneously, and then affects its service life.

Comprehensive above-mentioned reason, provides a kind of good heat dissipation effect, the convenient LED lamp housing with coupling different capacity of expansion to become a kind of urgent need.

Utility model content

The purpose of this utility model is to provide a kind of LED casing of tunnel lamp with heat sinking function, and this device is fixed for the installation of LED light source substrate on the one hand, dispels the heat for LED lamp simultaneously.

For achieving the above object, the technical solution of the utility model is: a kind of LED Tunnel Lamp heat-dissipating casing is provided, comprise: for bearing whole lamp weight and the expandable stent of each module location, left heat radiation module and the right heat radiation module of support both sides, and the middle module between left and right heat radiation module, each module is fixedly installed in described support by screw.

Preferably, described module comprises pedestal, fin, expansion screw; Described pedestal is tabular cuboid, and LED light source substrate installing hole is opened in bottom; Described fin is parallel to be fixed on described pedestal; Described pedestal two ends are provided with water joint, by described water joint, LED lamp cable-through hole are sealed, and prevent moisture seepage.

Preferably, described left and right heat radiation module also comprises outer surface, and described outer surface minor face is hypotenuse and is connected to described pedestal with arc transition, conveniently coordinates with described expandable stent.

Preferably, described fin surface is waveform, and water joint place fin length shortens, and leaves water joint installing space.

beneficial effect

Owing to having adopted technique scheme, a kind of LED Tunnel Lamp heat-dissipating casing described in the utility model integrates LED lamp fixing and heat sinking function is installed, the cable-through hole moisture leakage problems that the design of water joint can avoid external heat radiation shell to bring simultaneously, by increasing described expandable stent length, middle module quantity to adapt to different capacity LED light source pedestal, greatly simplified the structure of existing LED lamp, the little quality of volume is light, and the radiating mode simultaneously exposing is more conducive to the heat loss through convection of light fixture.Except described each module, remaining part is all general standard component, is therefore applicable to doing automation standard production, has applied the light fixture of LED Tunnel Lamp heat-dissipating casing technology, and totle drilling cost will significantly reduce, and production efficiency improves.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is left and right heat emission module structure schematic diagram;

In figure: 1 expandable stent, 2 right heat radiation modules, module in 3,4 left heat radiation modules, 5 light source substrates, 6 fin, 7 pedestals, 8 expansion screw, 9 outer surfaces, 10 water joints.

The specific embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is further described:

As shown in Figure 2: each module that dispels the heat comprises fin 6, pedestal 7, expansion screw 8, water joint 10; Fin 6 is parallel to be fixed on described pedestal 7, and described pedestal 7 bottoms have light source substrate 5 screwed hole is installed; Described fin 6 outer surfaces are waveform, increase area of dissipation; Described water joint 10 is located at described pedestal 7 two ends; Water joint 10 place's fin 6 length are shorter, are reserved with water joint 10 installing spaces; Left heat radiation module 4 and right heat radiation module 2 also comprise outer surface, and described outer surface 9 is for hypotenuse and be connected to described pedestal 7 with arc transition, conveniently coordinates 1 with expandable stent.

When LED power causes more greatly the 5 specifications increases of LED light source substrate, radiating requirements to increase, can mate by increasing the quantity of expandable stent 1 length and middle module 3, by expansion screw 8, fixedly mount.

First the heat that LED lamp produces is passed to the pedestal 7 of direct contact, pedestal 7 adopts the good metal material of heat conduction to make, pedestal 7 conducts to heat described fin 6 then, outer being exposed in air of described fin 6, directly by cross-ventilation, dispel the heat, by corrugated outer surface design, can increase area of dissipation, strengthen radiating effect.By the water joint 10 being provided with, prevent that moisture is from LED cable-through hole seepage.

Applied specific embodiment herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof.The above is only preferred embodiment of the present utility model, should be understood that, finiteness due to literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characterictic can be combined by rights; These improve retouching, change or combination, or without improving, the design of utility model and technical scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
