Abstract

The utility model discloses an LED (light-emitting diode) power-type support, which can effectively lead out heat produced by high power LEDs, medium power LEDs and modular LEDs, and further achieve LED direct insertion welding or surface welding (SMD). The technical scheme is that the LED power-type support mainly comprises an LED support with flying wings, a heat conduction column and a fixing material, wherein, the LED support with the flying wings is bonded with the heat conduction column through the fixing material. The utility model breaks through the frame that the high power LEDs cannot achieve direct insertion welding, broadens the application range of the high power LEDs, and expands the use space of the high power LEDs; and compared with the high power support in the prior art, the LED power-type support requires lower material cost, lower production cost and lower process technology than the high power support in the prior art.

Description

LED power-type support

Technical field

The utility model relates to a kind of led support, relate in particular to a kind of heat that can derive high-power, middle power, modularized limit emitting diode (LED) generation effectively, can realize simultaneously welding of LED straight cutting or surface soldered (SMD) again, a kind of LED power-type support, belong to LED manufacturing technology field.

Background technology

The LED light-emitting component is because little, the less energy consumption of its volume, long service life, the energy-conserving light source that is considered to a new generation, yet heat radiation is the bottleneck of restriction LED to high-power development always, therefore prior art is under the common needs of considering heat radiation and welding etc., the high-power LED bracket that adopts can only be done surface welding (SMD) on welding manner, this just limited greatly LED manufacturing, use and develop.

Summary of the invention

For solving the deficiencies in the prior art, this patent has aimed to provide a kind of heat that can derive high-power, middle power, modularized limit emitting diode (LED) generation effectively, can realize a kind of LED power-type support of welding of LED straight cutting or surface soldered (SMD) simultaneously again.

For achieving the above object, the technical program is: a kind of LED power-type support, and it mainly is made up of led support, heating column, the immobilization material of band all-wing aircraft, and the led support of described band all-wing aircraft is bonding by immobilization material and heating column.

On Type of Welding, when needs are implemented surface soldered (SMD), the all-wing aircraft of the led support of band all-wing aircraft is implemented welding with the upper surface of pcb board, realization surface soldered (SMD); When the needs straight cutting welds, the led support pin of described band all-wing aircraft is made electrode, make the led support pin of band all-wing aircraft and the back side of PCB wiring board implement welding, realize the straight cutting welding.

Feature of the present utility model also is:

Described heating column can be metal material as copper and copper alloy, aluminium and aluminium alloy, magnesium and magnesium alloy etc.; Nonmetallic materials are as silicon, pottery, carbon fiber etc.; Various composite materials have also been comprised;

The led support of described band all-wing aircraft, the preferred iron of material and iron-based material or copper and copper alloy material that it uses.

Described immobilization material, in heat conduction whether, all allow variation on the material material, fixed form.

The all-wing aircraft of the led support of described band all-wing aircraft is allowing variation in shape.

After adopting technical solutions of the utility model, the usefulness of this patent structure is:

1, this patent has been broken through the circle that high-power LED bracket can not realized the straight cutting welding, has enlarged the range of application of great power LED, has enriched the usage space of great power LED.

2, broken through the barrier of existing LED power support patent (U.S. LUMILEDS company high-power LED bracket patent of invention).

3, broken the prejudice that traditional LED can not do great power LED.

4, compare with the high-power support of prior art, the material cost of the art of this patent, production cost, technology all are lower than the high-power support of prior art.

The purpose of this utility model, feature and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.

Embodiment

Referring to Fig. 1, Fig. 1 is a prior art typical structure schematic diagram, and as shown in the figure, because reasons in structure, it can only do surface welding (SMD).

Referring to Fig. 2,3,4,6, as shown in the figure, the utility model mainly is made up of led support 2, heating column 1, the immobilization material 3 of band all-wing aircraft, and the led support 2 of described band all-wing aircraft is bonding by immobilization material 3 and heating column 1.

The embodiment of this patent LED power-type support packaged high-power LED element is: fixed L ED chip 4 on heating column 1, be connected to form electronic circuit with plain conductor 6 and led chip 4 and the led support 2 of being with all-wing aircraft again, and then sealing resin colloid 5, then solidified forming gets final product.

Compared with prior art, well heat conduction of the utility model, heat radiation, can realize the encapsulation of traditional LED again, and take straight cutting welding or surface soldered (SMD) according to different needs, when needs are implemented surface soldered (SMD), with being with the all-wing aircraft 7 of the led support of all-wing aircraft to implement welding, realize surface soldered (SMD) with the upper surface of pcb board; When the needs straight cutting welds, the led support pin one 0 of described band all-wing aircraft is made electrode, make the led support pin one 0 of band all-wing aircraft and the back side of PCB wiring board implement welding, realize the straight cutting welding.

Fig. 5 is this use embodiment distressed structure commonly used structurally; its difference is; installed support insulation plastic packaging overcoat 9 additional; this example has illustrated that also the technical program is that permission is vicissitudinous on contour structures, any simple deformation on the technical program basis should belong within the utility model protection range.

Obviously, the foregoing description only supplies the usefulness of explanation the utility model, and is not to restriction of the present utility model, and the variation that the those of ordinary skill in relevant technologies field is made in the corresponding techniques field according to the utility model should belong to protection category of the present utility model.
