The radiator connected with the lamp holder face is adopted, and the heat generated by the LEDs is transferred to the radiator and the lamp holder by the metal substrates, so that the working temperature of the LED illuminants is reduced, the working lives of the illuminants are prolonged, and a foundation is provided for further improving the luminous power of the illuminants.

Description

A kind of LED lamp

Technical field

The utility model relates to a kind of lighting, particularly a kind of illuminating LED lamp.

Background technology

Bulb has adopted LED as illuminator at present, LED is connected with metal substrate, by metal substrate the unnecessary heat that illuminator produces is distributed, avoid illuminator to damage owing to overheated, the shortcoming of this structure is that metal substrate is installed in the bulb, its size is restricted, thereby area of dissipation is limited, can not reduce the heat that illuminator produces better, make illuminator be in higher operating temperature, thereby influence the working life of illuminator, the luminous power of bulb also can't further improve simultaneously.

The utility model content

The utility model enlarges area of dissipation and the heat dissipation of illuminator by metal substrate is connected with the radiator of heat conduction, improves the working life of illuminator, provides the basis for the luminous power that further improves illuminator simultaneously.

For achieving the above object, the utility model provides a kind of LED lamp, comprise, and lamp socket, lampshade and illuminator, wherein, and lamp socket, inside has cavity, and the drive circuit of illuminator is installed in the cavity; Lampshade is the thin transparent housing, and the lower end is connected with lamp socket, and illuminator is housed in the thin walled shell; Also be provided with in the lampshade with lamp socket and have the radiator that face is connected, radiator is made by the insulating materials of heat conduction, and metal substrate passes radiator and fits with radiator, and the heat that illuminator is produced passes to radiator by metal substrate; Illuminator is LED, and illuminator is connected with metal substrate, extends in the lamp socket with drive circuit in the lamp socket by metal substrate to be connected.

In the technique scheme, the plate body that radiator is made by the ceramic material of heat conduction.

In the technique scheme, lamp socket has the plane of applying radiator towards the end face of metal substrate, is connected with the plate body realization face of radiator by the plane, and lamp socket is given in the conduction of being convenient to heat, further increases area of dissipation.

In the technique scheme, lamp socket has the caulking groove of chimeric radiator towards the end face of metal substrate, and the plate body of radiator embeds in the caulking groove and is connected with lamp socket, and the realization radiator is connected with the face of lamp socket.

In the technique scheme, metal substrate is single or a plurality of, and a plurality of metal substrates make that around setting illuminator can be towards different direction of illuminations.

Compared with prior art, the utility model is by arranging the radiator that is connected with the lamp socket face, the heat that LED is produced passes to radiator and lamp socket by metal substrate, reduce the operating temperature of LED illuminator, improve the working life of illuminator, provide the basis for the luminous power that further improves illuminator simultaneously.

The specific embodiment

Below in conjunction with accompanying drawing, two specific embodiment of the present utility model are described in detail, but are to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.

Embodiment 1

A kind of LED lamp of the present utility model comprises, lamp socket 1, lampshade 2 and illuminator 4; Lamp socket 1, inside has cavity, and the drive circuit 6 of illuminator is installed in the cavity, and the lower end of lamp socket 1 is socketed with the connector 7 that is electrically connected with the external world; Lampshade 2 is the thin transparent housing, and the lower end is connected with lamp socket 1, and illuminator 4 is housed in the thin walled shell; Also be provided with in the lampshade 2 with lamp socket and have the radiator 5 that face is connected, the plate body that radiator 5 is made by the ceramic material of insulation, metal substrate 3 passes radiator 5 and fits with radiator 5, and the heat that illuminator 4 is produced passes to radiator 5 by metal substrate 3; Illuminator 4 is LED, and illuminator 4 is connected with metal substrate 3, extends to lamp socket 1 drive circuit 6 interior and in the lamp socket by metal substrate 3 and is connected;

Further as shown in Figure 1, lamp socket 1 has the plane of applying radiator towards the end face of metal substrate 3, is connected with the plate body realization face of radiator 5 by the plane, and lamp socket is given in the conduction of being convenient to heat, further increases area of dissipation.

Further as shown in Figure 1, metal substrate 3 is a plurality of (also can be single), and concrete quantity determines that according to the irradiation needs of illuminator a plurality of metal substrates make that around setting illuminator can be towards different direction of illuminations.

Embodiment 2

Embodiment 2 as shown in Figure 2, embodiment 2 is with the difference of embodiment 1, lamp socket 1 has the caulking groove of chimeric radiator 5 towards the end face of metal substrate 3, the plate body of radiator 5 embeds in the caulking groove and is connected with lamp socket 1, realization radiator 5 is connected with the face of lamp socket 1.
