Abstract
The utility model discloses an LED lamp convenient for changing the size of a radiator. The LED lamp consists of an LED chip and the radiator which is in thermal contact with the LED chip, wherein the radiator is of a finned tube which is in thermal contact with the LED chip; and the end part of the finned tube body is provided with a connector abutted with another finned tube. The LED lamp has advantages of being capable of changing the size of the radiator by being connected with different quantities of finned tubes, being combined into the radiator with different shapes only by being configured with bent finned tubes, and facilitating the installation of the LED lamp on special occasions.
Description
Technical field
The utility model relates to light fixture, particularly with the LED light fixture of light-emitting diode chip for backlight unit as light-emitting component.
Background technology
The LED light fixture is a kind of with the LED light fixture of light-emitting diode chip for backlight unit (below be referred to as " led chip ") as light-emitting component.This light fixture generally all has a radiator with the led chip thermo-contact.In existing LED light fixture, with radiator generally all be to stretch or casting forms by aluminium, perhaps fire to form by ceramic material.To finish the back just fixing stretching, cast or fire for the shape of entire radiator and size.Yet the required heat sink size of LED light fixture of different capacity has nothing in common with each other, so just the have nothing for it but LED light fixture of various different capacities of the producer of LED light fixture is equipped with the radiator differ in size, has brought trouble to production management.
The utility model content
The purpose of this utility model provides a kind of LED light fixture of being convenient to change heat sink size.
The utility model be achieved in that the LED light fixture of being convenient to change heat sink size comprise led chip and with the radiator of led chip thermo-contact, described radiator is a finned tube, finned tube and led chip thermo-contact, the body end of finned tube is provided with the joint that docks with another root finned tube.Rely on this joint, the finned tube that connects varying number just can change the size of entire radiator, to adapt to the LED light fixture of different capacity.So, the producer of LED light fixture just need not to be equipped with the radiator that differs in size for the LED light fixture of different capacity, has brought convenience to production management.
The utility model has the advantages that the size of not only being convenient to change radiator, and, be convenient to the installation of LED light fixture under special occasions as long as the crooked finned tube of configuration just can be combined into difform radiator.

The specific embodiment
Referring to Fig. 1, the LED light fixture of being convenient to change heat sink size comprise led chip 1 and with the radiator of led chip thermo-contact.Described radiator is a finned tube.The body 2 of finned tube can be copper pipe or aluminum pipe.Aluminium base 3 bonding of the lower end of body 2 and led chip 1 makes led chip 1 and body 2 thermo-contacts with this.The fin 4 that is fixed on the body 2 can be stamped to form with aluminium flake.The body 2 of present embodiment is a hollow pipe, its upper end can with another root finned tube socket, and can connect more finned tube by that analogy.Be exactly multi-link two finned tubes on the basis of Fig. 1 as shown in Figure 2.Present embodiment in fact be exactly directly with the end of the body of finned tube as the joint that docks with another root finned tube.
In the embodiments of figure 3, be that with the difference of Fig. 1 the end global formation of the body 2 of finned tube has ring flange 5, body 2 docks with another root finned tube by ring flange 5, as shown in Figure 4, thus present embodiment be exactly that ring flange with the body end of finned tube is as the joint that docks with another root finned tube.The ring flange of the body of two butt joints can be connected and fixed with screw.Other structures of present embodiment are identical with Fig. 1.
If the body of finned tube is crooked, just can be combined into difform radiator.For example in Fig. 2 or Fig. 4, if the body of a middle finned tube 6 crooked 90 degree just can be formed a radiator that is " 7 " font, by that analogy, if connect more finned tube, and the different finned tube of combination angle of bend, just can be combined into the different radiator of shape.Satisfy the installation requirement of LED light fixture under special occasions.
For strengthening radiating effect, on the fin of finned tube, can also install more fin additional.Be exactly embodiment for example shown in Figure 5 has increased axial fin 7 on the basis of Fig. 1, axial fin 7 is inserted on radially the fin 4, total increased the area of dissipation of finned tube.
For strengthening radiating effect, in the body 2 of finned tube, can be packaged with liquid, solid or the gas that helps heat conduction.
