Abstract

The utility model discloses a LED lamp subassembly, which comprises a LED lamp unit and a lamp stand, wherein the LED lamp unit is provided with at least one heat yielding conductive blade, at least one LED light-emitting component and a LED power supply drive module; the lamp stand comprises at least one socket and radiating seat; the power socket is set on the radiating seat, the LED lamp is mounted on the power socket, and the radiating seat contacts with the heat yielding blade of the LED lamp. When the LED lamp is mounted on the power socket, the heat yielding blade on external side of the LED lamp contacts with the radiating seat on the lamp stand, which expands heat yielding area of the heat yielding blade of the original LED lamp, and improves heat yielding efficiency; and the lampsubassembly is convenient for use and daily maintenance.

Description

The LED lamp assembly

Technical field

The utility model relates to a kind of LED lamp assembly, refers to that especially a kind of LED light fixture and lamp socket thereof have the lamp assembly of heat radiation function concurrently.

Background technology

Along with the continuous development of LED lighting apparatus, also weed out the old and bring forth the new at the solution of its PN junction heat radiation.As shown in Figure 1, Chang Yong LED light fixture now, be between LED lampshade 1 ' and lamp holder 2 ', to be provided with heat radiation guide card 3 ', it can solve the problem that heat energy is piled up in the middle position of LED to a certain extent, but because the heat-conducting area of heat radiation guide card 3 ' is limited, the long-time use, heat still can't be fast to external diffusion, if on a lamp socket, arrange a plurality of LED bulbs, between bulb and bulb since spacing be not very big, easily because of the radiant heat of self bulb, and influence adjacent bulb, cause the heat energy of each bulb to get rid of effect and be subjected to serious obstruction.And then the dealer improves at the problems referred to above, referring to the patent No. is ZL200820118546.7, name is called the Chinese utility model patent of " Lamp Combined Structure that possesses heat radiation function ", it installs a heat sink 23 (as shown in Figure 2) additional on the basis of original LED heat radiation guide card 21, to increase the area of dissipation of original LED heat radiation guide card 21, but because this heat sink 23 designs for split with supply socket 31, between heat sink 23 and supply socket 31 is confined space, be unfavorable for heat to external diffusion; In addition,, in the time of need changing, can only earlier heat sink 23 be pulled down, in the replacing of carrying out light fixture 20, waste time and energy then in case the LED light fixture breaks down.

The utility model content

The purpose of this utility model is to provide a kind of LED lamp assembly, and its integral heat sink effect height in the service life of prolongation LED light fixture, is convenient to the replacing of LED fault light fixture simultaneously.

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

A kind of LED lamp assembly comprises LED lamp unit and lamp socket, and this LED lamp unit is provided with at least one heat radiation guide card, at least one LED light-emitting component and LED electric power driving module; This lamp socket comprises at least one socket and radiating seat; Supply socket is arranged on the radiating seat, and the LED lamp installation is in supply socket, and the heat radiation guide card of radiating seat and LED light fixture is in contact with one another.

Described radiating seat is made of radial vertical fin of arranging, and the middle part is made as the hollow-out parts of putting supply socket, and the top of this hollow-out parts is provided with a boss.

Described boss is the some penetrating louvres of distribution evenly.

Described hollow-out parts is used to put supply socket.

Described radiating seat can be provided with a plurality of, interconnects between radiating seat and the radiating seat.

Described lamp socket can be set up a substrate that is used to put radiating seat.

After adopting such scheme, because the supply socket on the utility model lamp socket is arranged on radiating seat, when the LED lamp installation in supply socket, the heat radiation guide card in its LED light fixture outside contacts with the radiating seat on the lamp socket, increases the dispel the heat area of dissipation of guide card of original LED light fixture greatly.

At the radiating seat that is made of radial vertical fin of arranging, its fin is exposed outside in addition, and heat is difficult for the inside of productive set lamp socket, the radiating efficiency height; In case the LED light fixture breaks down simultaneously, only need lampshade to be taken off (some lamp assembly is not provided with outside lampshade), carry out the replacing of fault light fixture, so this lamp assembly is very convenient when use and regular maintenance.

The specific embodiment

Shown in Fig. 3,4,, comprise LED lamp unit 1, lamp socket 2 and lampshade 3 for the utility model possesses the structural representation of the LED lamp assembly embodiment one of heat radiation function.

Described LED lamp unit 1 is provided with heat radiation guide card 4, at least one LED light-emitting component 5 and a LED electric power driving module (not shown) at least; Described heat radiation guide card 4 is between LED light-emitting component and lamp holder 6.

Described lamp socket, comprise socket 7 and radiating seat 8 that suitable power specification is provided, radiating seat 8 is arranged by radial vertical fin 9 ring-types of arranging, the middle part hollow out, the top of hollow-out parts is provided with a boss 10, some penetrating louvres 11 that evenly distribute on the boss, and described hollow-out parts is used to put supply socket 7, when LED light fixture 1 is installed in supply socket 7 on the lamp socket, radiating seat 8 need be in contact with one another with the heat radiation guide card 4 of LED light fixture 1.

The operation principle of this LED lamp assembly is: have heat radiation guide card LED lamp unit 1 and be installed on the radiating seat 8 that is provided with supply socket 7, when light fixture is started working, heat at first is passed to heat radiation guide card 4 from the PN junction of LED, because the boss 10 of the metal material on heat radiation guide card 4 and the radiating seat 8 is in contact with one another, boss 10 is provided with some penetrating louvres 11 simultaneously, but accelerated heat is transmitted to fin 9 like this, because fin 9 can directly contact with the external world, therefore heat can carry out heat exchange with the external world very fast, the final heat of realizing that the LED luminescence unit is produced can rapidly and efficiently transmit to the external world, reach the purpose of cooling, prolong the service life of LED light fixture; In case the LED light fixture breaks down simultaneously, can directly change, and need not carry out the dismounting heat sink, the convenient use the fault light fixture.

As Fig. 5,6 is the structural representation of the utility model embodiment two, the structure of its LED lamp unit, lamp socket and both matching relationships and embodiment one are similar substantially, uniquely distinct be, the solution that this embodiment provides a plurality of light fixtures to cooperate with a plurality of radiating seats, promptly, interconnect between the radiating seat 8, and be installed on the lamp socket substrate 12 (also can be one-body molded between the same radiating seat 8, and need not to be installed on the lamp socket substrate 12).So not only improve the brightness of illumination of lamp assembly, and interconnect between the radiating seat, enlarge area of dissipation, also help the heat that each LED luminescence unit produced and transmit to the external world.

Above-mentioned two embodiment are two preferred embodiments of the utility model, and the emphasis of the utility model protection is: the LED supply socket is arranged on the radiating seat, and the heat radiation guide card of this radiating seat on can the LED light fixture is in contact with one another.
