Description

Thermoelectricity separate package LED

Technical field

The utility model relates to LED lamp of automobile, particularly relates to a kind of thermoelectricity separate package LED.

Background technology

That uses on automotive lighting along with LED product gets more and more, and reliability when using LED and service life require more and more higher, make to have higher requirement to the radiating treatment of LED, particularly to high-power LED.The heat dissipation bonding pad of some LED is connected with the negative pole of LED, heat dissipation channel and interior circuit is caused to communicate, the LED group of design on same pcb board can not share same heat radiation Copper Foil (or radiator), between LED, heat radiation there are differences thus, LED dispels the heat inequality, the reliability that impact uses and life-span.

Utility model content

Technical problem to be solved in the utility model is exactly for above shortcomings in prior art, provides a kind of thermoelectricity separate package LED, for solving the problems of the prior art.

For achieving the above object and other relevant objects, the utility model provides a kind of thermoelectricity separate package LED, comprise from pushing up the LED group, conductive welding disk, insulating barrier, aluminium base and the thermal land that set gradually the end of to, described conductive welding disk connects the power circuit of LED electrical pole, and described thermal land directly contacts with aluminium base.

Further, described LED group is made up of the LED of the thermoelectricity separate package of three series connection.

Further, described LED group is connected with outside DC current or AC power.

By above technical scheme, the utility model has following technique effect compared to prior art: improve LED radiating efficiency, optimizes heat radiation between LED uneven, reduce fault, improve LED luminous efficiency, promote the dependability of LED, thus increase the service life.

Detailed description of the invention

By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present utility model and effect easily.

Refer to Fig. 1 to Fig. 3.Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.

Consult shown in Fig. 2, the utility model provides a kind of thermoelectricity separate package LED, comprise from pushing up the LED group, conductive welding disk 2, insulating barrier 3, aluminium base 4 and the thermal land 5 that set gradually the end of to, conductive welding disk 2 connects the power circuit of LED 1 electrode, and thermal land 5 directly contacts with aluminium base 4.

Consult shown in Fig. 1, LED group is made up of the LED 1 of three series connection.Consult shown in Fig. 3, the conductive electrode tandem connection of 3 LED lamp, input and output terminate to drive circuit, are then connected with the DC current of outside or AC power.While ensureing circuit function, the heat of 3 LED lamp is led fast on aluminium base 4 simultaneously and is dispelled the heat, and ensure that LED heat radiation is good, heat radiation uniformity is high, improves LED dependability and service life.The utility model can be applicable in the systems such as such as automotive lighting, street lighting or Landscape Lighting.

In sum, the utility model can improve LED radiating efficiency, optimizes heat radiation between LED uneven, reduces fault, improve LED luminous efficiency, promote the dependability of LED, thus increase the service life.So the utility model effectively overcomes various shortcoming of the prior art and tool high industrial utilization.

Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
