Abstract

The utility model relates to a high-power light-emitting diode (LED) lamp, which comprises a lamp cap, a lamp holder, a heat sink, a chassis, a thermal column, an LED luminous body and a lampshade, wherein the lamp holder is matched with the lamp cap; the heat sink is matched with the lamp holder; the chassis, the thermal column, the LED luminous body and the lampshade are matched on the heat sink; the thermal column completely extends into the heat sink; the LED luminous body comprises a circuit board and a plurality of LED lamp beads distributed on the circuit board; the LED luminous body is arranged at the end part of the thermal column and is connected with a transformation circuit board in the lamp hold through a lead, thereby, heat generated by the LED luminous body can be rapidly transferred to the heat sink through the thermal column, and the heat is dissipated to air in time by metal fins of the heat sink so as to meet the heat dissipation requirement of the high-power LED lamp and ensure the service life of the lamp.

Description

A kind of high-powered LED lamp

Technical field

The utility model relates to the field of lighting apparatus, is meant a kind of high-powered LED lamp especially.

Background technology

LED(Light Emitting Diodes, light emitting diode) with characteristics such as its energy-conserving and environment-protective, luminous efficiency height, life-span length, obtain application more and more widely, LED is applied to various illuminations place as a kind of novel solid light source.

And existing LED lamp all is to be combined with LED lamp pearl on circuit board, form the radiation modality of spot light, therefore can occur LED lamp pearl over against direction brighter, and range of exposures is limited, the brightness that improves its irradiation as desire also is to adopt the quantity that increases LED lamp pearl to realize, high-powered LED lamp is to adopt the lamp pearl to concentrate the mode of arranging, reach the irradiation of high brightness on a large scale, therefore must consider the heat dissipation problem of light source, mostly the heat abstractor of tradition high-powered LED lamp is to adopt the radiator structure of many fins, thereby volume is all bigger, and rely on merely on the light source base open area of light source and the metal material of cooperation pedestal itself are realized that the form of heat radiation can't satisfy the heat radiation requirement of high light large power LED lighting apparatus, thereby limited the service life of highlight illumination equipment.

The utility model content

The purpose of this utility model provides and a kind ofly can realize the high-powered LED lamp of highlight illumination on a large scale, and its compact conformation has preferable radiating effect, to guarantee the service life of light fixture.

For achieving the above object, technical solution of the present utility model is:

A kind of high-powered LED lamp includes lamp holder, the lamp socket that cooperates with lamp holder, the radiator that cooperates with lamp socket, is matched with chassis, plume, LED illuminator and lampshade on the radiator; Wherein this plume is stretched and is placed radiator, and this LED illuminator is made up of a circuit board and a plurality of LED lamp pearls of being distributed on the circuit board, and the LED illuminator is installed in the end of plume and connects transforming circuit plate in the lamp socket by lead.

This radiator comprises auxiliary heat dissipation body and main radiator, and main radiator is one to have the sleeve of mantle cavity, the radial metal fins that is placed with of its periphery, and the upper end of main radiator and auxiliary heat dissipation body link together, and the lower end connects the chassis.

This plume passes the chassis and stretches the mantle cavity that places main radiator fully.

This auxiliary heat dissipation body is a radiator fan.

This plume is a cylindrical shell that is formed by Heat Conduction Material, is equipped with copper powder particle and the filling cooling fluid between copper powder particle in the shell.

After adopting such scheme, the utility model is because plume is to stretch fully in the mantle cavity that places main radiator, and the LED illuminator is installed in the end of plume, the heat that the LED illuminator can be produced by plume is rapidly to the radiator transmission, metal fins by radiator is distributed heat in air timely, satisfy the heat radiation requirement of high-powered LED lamp with this, ensure light fixture service life.

Description of drawings

Fig. 1 is a three-dimensional exploded view of the present utility model;

Fig. 2 is a combination schematic appearance of the present utility model.

The specific embodiment

As shown in Figure 1, 2, a kind of high-powered LED lamp of the present utility model comprises a lamp holder 1, a lamp socket 2, a radiator 3, a chassis 4, a plume 5, LED illuminator 6 and a lampshade 7.

Lamp holder 1 is connected with the top of lamp socket 2 by the cooperation of screw thread or buckle, is formed with block set on transforming circuit plate (not shown), the bottom to cooperate ccontaining auxiliary heat dissipation body 31 and be provided with in the lamp socket 2.

Radiator 3 comprises auxiliary heat dissipation body 31 and main radiator 32, auxiliary heat dissipation body 31 can adopt a radiator fan, and main radiator 32 is one to have the sleeve of mantle cavity 321, the radial metal fins 322 that is placed with of its periphery, the upper end of main radiator 32 and auxiliary heat dissipation body 31 link together, and the lower end connects chassis 4; Chassis 4 is one to have the ring plate of centre bore 41.

Plume 5 is a cylindrical shell that is formed by conductor material, be equipped with the cooling fluid between copper powder particle in the shell by copper powder particle and filling, copper powder particle has preferable heat conductivility, the cooling fluid gasification effectively can be transmitted heat to the low direction of temperature by the high end of temperature rapidly, form preferable heat carrier, LED illuminator 6 is installed in the end of plume 5, and this LED illuminator 6 is made up of a circuit board 61 and a plurality of LED lamp pearls 62 of being distributed on the circuit board.

Cooperate shown in Figure 2, during the combination of the utility model LED lamp, lamp holder 1, lamp socket 2, radiator 3 and chassis 4 fit together successively, plume 5 passes the centre bore 41 on chassis 4 and stretches the mantle cavity 321 that places main radiator 32 fully, and LED illuminator 6 is installed in the end of plume 5, and LED illuminator 6 connects transforming circuit plate (not shown) in the lamp socket 2 by lead, at last lampshade 7 covered in that LED illuminator 6 is outer to be fixed together the composition high-power LED lamp with chassis 4.

As seen above-mentioned, high-powered LED lamp of the present utility model is because plume 5 is to stretch fully in the mantle cavity 321 that places main radiator 32, and LED illuminator 6 is arranged on the end of plume 5, the heat that LED illuminator 6 can be produced by plume 5 transmits to radiator 3 rapidly, metal fins 322 by radiator 3 is distributed heat in air timely, satisfy the heat radiation requirement of high-powered LED lamp with this, ensure light fixture service life.
