Abstract
The utility model relates to a combined heat dissipation structure of an LED (light-emitting diode) lighting lamp. The utility model is characterized in that the combined heat dissipation structure comprises an LED aluminum base plate, a heat dissipation main body, a heat dissipation turbofan and a thermal-radiation heat dissipation back cover, wherein the aluminum base plate clings to the heat dissipation main body, the heat dissipation turbofan is arranged on the heat dissipation main body, and the heat dissipation turbofan is fixed on a fan fixing support. The combined heat dissipation structure has the advantages that when the combined heat dissipation structure is used, the LED light source aluminum base plate is adhered to the front surface of the heat dissipation main body in a locking way, so that the heat conducting surface of the heat dissipation main body is adhered to the plane of the LED light source aluminum base plate. When in operation, the heat of the heat dissipation main body is blown out of an enclosure by the heat dissipation turbofan, and the heat in a shell radiates to the back cover and is dissipated through the convection in a way that the back cover is in direct contact with the air. The heat generated by the LED light source is carried away from the heating source continuously; therefore, the phenomenon of hot stack does not happen. With the adoption of the heat dissipation structure, the size of the lamp can be smaller, the occupied space can be effectively reduced, and the volume of a heat dissipation body is not increased with the increase of the power; besides, the combined heat dissipation structure can help the LED lighting lamp improve towards the direction of lightening and space miniaturization.
Description
Technical field
The utility model relates to heat dissipation technology, relates in particular to a kind of heat dissipation technology of LED lighting.
Background technology
Existing LED lighting heat abstractor; LED, aluminium sheet, shell separate; Its shell adopts plastic parts to prop up overfill protection; Main aluminium extruded or the aluminium extruded of leaning on of its heat radiation adds conventional fan, do not have other heat radiation approach, and radiating effect is relatively poor. cause hot stack easily. and when inside is full of hot-air. can have a strong impact on the life-span of fan.
Summary of the invention.
What the utility model proposed is a kind of integrated Projecting Lamp heat abstractor, and its purpose is intended to overcome the above-mentioned defective that prior art is deposited.The technical solution of the utility model: its structure comprises LED aluminium base, heat radiation main body, heat radiation turbofan, heat loss through radiation back of the body lid, and wherein aluminium base is close to the heat radiation main body, and the heat radiation main body is provided with the heat radiation turbofan, and the heat radiation turbofan is fixed on the fan Fixture.The advantage of the utility model: owing to be welded with the aluminium base of LED is that locking is on the radiator of shell.Adopt 6063 aluminum alloy casings to conduct heat naturally; LED lamp pearl is lighted the thermal source that is produced; Be delivered on the heat radiation main body through aluminium base, start quick the flowing of heat radiation turbofan forced air and contact convection current, the continual heat of taking out of with the heat radiation body surfaces; Thereby reach a temperature equalization point, it is not damaged service life because of heat can't shed.
Description of drawings
Accompanying drawing 1 is the sketch map that radiator structure does not add heat loss through radiation back of the body lid;
Accompanying drawing 2 is to show heat radiation main body, heat radiation turbofan but the radiator structure sketch map that do not add heat loss through radiation back of the body lid;
Accompanying drawing 3 is that the radiator structure loading heat loss through radiation back of the body covers view.
Among the figure 1 is LED aluminium base, the 2nd, heat radiation main body, the 3rd, heat radiation turbofan, the 4th, heat loss through radiation back of the body lid.
The specific embodiment
Contrast accompanying drawing 1, its structure comprise LED aluminium base 1, heat radiation main body, heat radiation turbofan, heat loss through radiation back of the body lid, and wherein aluminium base 1 is close to the heat radiation main body, and the heat radiation main body is provided with the heat radiation turbofan, and the heat radiation turbofan is fixed on the fan Fixture.
Said heat radiation turbofan is one or more.There is a heat loss through radiation bonnet at the heat radiation turbofan back side.
Contrast accompanying drawing 2,3, this light fixture are attached to led light source aluminium base 1 on the heat radiation main body in use, and its bottom surface is pasted with heat radiation main body 2 planes mutually.In led light source when work, is when the heat that is sent conducts on the heat radiation main body. via heat radiation turbofan 3 heat blown out again.Owing to be airtight space. when fan can't blow out heat fully. the heat radiation of all the other to the heat loss through radiation back of the body covers on 4. and cover 4 direct contacts by the heat loss through radiation back of the body and carry out convection current with air. heat is dissipated.So, the heat on the light source of LED lighting will be with from pyrotoxin endlessly, therefore, can on led light source, not produce the hot stack phenomenon, and can effectively reduce the radiating module occupation space.This radiator structure can not increase the volume of heat radiation module because of the increase of power, helps lighting to lighting, cost degradation and miniaturization development.
