Description

A kind of LED pressure mounting structure

Technical field

The utility model relates to the mounting structure of a kind of LED.

Background technology

Present LED light fixture on the market, the mounting structure of its LED is that employing LED directly is welded on the means on the aluminium base circuit board mostly.Though improved the firm degree of the installation of LED like this; and heat can distribute by aluminium base; can not closely contact with radiator but usually can cause LED because operating temperature relaxes because of pad, the LED heat can not effectively be derived, and causes LED to fall greatly service life or burns out.Other mounting structure then is that the below of LED itself is provided with conducting strip, and conducting strip and radiator are fitted.Heat during LED work just is delivered to radiator by conducting strip, is responsible for dispelling the heat to LED by radiator.Yet this mounting structure can't guarantee that the conducting strip of LED can constantly closely contact with radiator, after the two unclamps, has just had air heat-insulation layer between them, is unfavorable for the timely transmission of heat and distributes.Even in the prior art, can between conducting strip and radiator, be coated with the last layer heat-conducting glue and guarantee the heat transmission with attempt, also can lose efficacy but grown heat-conducting glue service time.

The utility model content

The technical problems to be solved in the utility model is: a kind of LED pressure mounting structure is provided, and it can allow LED need not to be welded on the circuit board, also can be for a long time more firmly keep and radiator between heat transfer relation, guarantee radiating effect, prevent from burning out.

The solution that the utility model solves its technical problem is:

A kind of LED pressure mounting structure comprises radiator and LED, also comprises the pressure apparatus of exerting pressure, make itself and radiator to be adjacent to LED.

As further improvement in the technical proposal, described LED comprises lamp body and the conducting strip that connects with the lamp body, and pressure apparatus contacts with the lamp body and exerts pressure, and conducting strip and radiator are adjacent to.

As further improvement in the technical proposal, described pressure apparatus comprises compressing tablet, and it contacts with the periphery of LED, and compressing tablet is provided with hole or the breach that exposes for LED, and compressing tablet connects with radiator and fixes.

The beneficial effects of the utility model are: the utility model utilizes pressure apparatus that LED is exerted pressure, itself and radiator are adjacent to, so LED need not to adopt the welding means, also can keep and radiator between good transfer of heat relation, increased the radiating effect of LED light fixture integral body, avoid the phenomenon that LED that cause also becomes flexible, comes off, burns out because the LED installation is not firm, prolonged service life.

After having adopted mounting structure of the present utility model, the assembling of LED light fixture just need not to re-use aluminium base circuit board, so just can reduce and produce and the follow-up maintenance expense, and the process of manufacture of no circuit board reclaims simply environmental protection more.

The utility model can be used in the production assembling of LED light fixture.

The specific embodiment

Below with reference to embodiment and accompanying drawing the technique effect of design of the present utility model, concrete structure and generation is carried out clear, complete description, to understand the purpose of this utility model, feature and effect fully.Obviously; described embodiment is a part of embodiment of the present utility model, rather than whole embodiment, based on embodiment of the present utility model; other embodiment that those skilled in the art obtains under the prerequisite of not paying creative work all belong to the scope that the utility model is protected.In addition, all connection/annexations of mentioning in the literary composition are not to refer to that singly member directly joins, and refer to and can connect auxiliary by adding or reducing according to concrete performance, form more excellent draw bail.

A kind of LED pressure mounting structure comprises radiator 1 and LED2, also comprises the pressure apparatus of exerting pressure, make itself and radiator 1 to be adjacent to LED2.

Be further used as preferred embodiment, described LED2 comprises lamp body and the conducting strip 3 that connects with the lamp body, and pressure apparatus contacts with the lamp body and exerts pressure, and conducting strip 3 and radiator 1 are adjacent to.The increase of conducting strip is in order better the LED heat to be taken out of, to be passed to radiator.

Be further used as preferred embodiment, described pressure apparatus comprises compressing tablet 4, and it contacts with the periphery of LED2, and compressing tablet 4 is provided with hole or the breach that exposes for LED2, and compressing tablet 4 connects with radiator 1 and fixes.

Embodiment 1:

See figures.1.and.2, described pressure apparatus also comprises with radiator 1 and compressing tablet 4 and connects, keeps the fixture 5 that compressing tablet 4 is pressed to LED2 the trend of radiator 1; Compressing tablet 4 has elasticity, and integral body is " Z " shape, the stage casing that has the epimere that contacts with the periphery of LED2, the hypomere that connects with radiator 1 and epimere and hypomere are connected together; Described fixture 5 is fastened on the hypomere of compressing tablet 4 on the radiator 1.

At this moment, compressing tablet 4 has been born the function of a kind of " shell fragment ", its hypomere is fixed on the radiator, epimere is made the shape that presses down in advance, when it cooperates with LED, because its elasticity, will produce downward pressure to LED, force related its conducting strip of LED to press to radiator, so guaranteed the relation that is adjacent to of LED and radiator, prevent from getting loose.And in order to allow compressing tablet 4 connect with radiator 1, fixture 5 can adopt forms such as buckle, rivet.Because this stiff end has been arranged, thus compressing tablet 4 just can press down, so fixture 5 has played the effect that compressing tablet 4 is pressed to LED2 the trend of radiator 1 of keeping.

Embodiment 2:

With reference to Fig. 3 and Fig. 4, described pressure apparatus also comprises with radiator 1 and compressing tablet 4 and connects, keeps the fixture 5 that compressing tablet 4 is pressed to LED2 the trend of radiator 1; Described compressing tablet 4 integral body are sheet ringwise, and interior ring is pushed down the periphery of LED2; Described fixture 5 has elasticity, and integral body is into " 7 " shape, and its lower end connects with radiator 1, and fixture 5 epimeres and the outer shroud of compressing tablet 4 connect or push down the outer shroud of compressing tablet 4; Described fixture 5 has a plurality of, arranges round LED2, pushes down compressing tablet 4 jointly.

In order to increase the reasonability in application of force orientation, several (the being generally 4) fixture 5 that has designed annular compressing tablet 4 especially and lain around.At this time, fixture 5 plays the effect of " Elastic buckle ", and it presses down compressing tablet 4, thereby pushes down LED2, so can guarantee the applying relation of LED2 and radiator 1 equally and compress trend.

Embodiment 3:

With reference to Fig. 5, adopt spring as fixture 5, both ends of the spring connects with compressing tablet 4 and radiator 1 respectively.Like this, compressing tablet 4 has nonelastic with regard to it doesn't matter, because spring can be drop-down with compressing tablet 4, pushes down LED.
