Abstract

The utility model provides a radiating structure of light -emitting diode (LED) module which levels through guaranteeing heat dissipation base back surface, makes it reach the mesh that changes heat dissipation power in a flexible way through assembling different heat radiation fins to the shell that can use lamps and lanterns dispels the heat, through increasing module cover structure, the heat -sinking capability of LED module has been strengthened to can use in the application scenario that has closed shell lamps and lanterns.

Description

A kind of radiator structure of LED module

Technical field

The utility model belongs to field of LED illumination, relates to a kind of radiator structure of LED module.

Background technology

At present, in field of LED illumination, LED module, as the important component part of light fixture, obtains increasing attention.LED is semiconductor devices, and junction temperature is directly connected to its reliability, life-span and light efficiency.Therefore, heat dissipation design becomes a link that must think better of in the design of LED modular structure.

Known LED module is made up of optical element, LED lamp panel, module cooling base three part, and wherein cooling base is with radiating fin, and LED lamp panel is fixed on cooling base with bolt or heat-conducting glue, is dispelled the heat by the radiating fin of cooling base.The subject matter of this radiator structure is: 1) in certain working environment, and the surface area of radiating fin determines its heat-sinking capability.Because radiating fin and cooling base are integrated, the power that LED module can dissipate is determined, for different power grades, needs the cooling base developing different size, lacks flexibility.2) light fixture such as part street lamp, often has independently outer cover, is enclosed in by the radiating fin of LED module in a narrow space, make its cannot directly and environment carry out heat exchange, cause the deterioration of LED module heat dispersion.

Summary of the invention

For the radiator structure solving the existence of existing LED module is dumb, to problems such as closed light fixture heat dispersion differences, the utility model proposes a kind of radiator structure of new LED module.This radiator structure not only increases the heat radiation flexibility of LED module, has expanded the operational power bracket of LED module, has also enhanced its heat dispersion, can realize good radiating effect in the application scenario with closed shell light fixture.

The utility model solves the technical scheme that its technical problem adopts:

1) convex is made at the cooling base back side of LED module.Convex surfacing, for the radiating fin installing different size, or can be connected with the inner surface of lamp outer casing.On the one hand, when LED module is applied to the occasion of different capacity grade, only need selects the radiating fin of different size, be installed on the platform at the cooling base back side, thus can simplified design, improve the flexibility of LED module.On the other hand, the lamp outer casing that it is plane that part light fixture can use with inner surface, thus LED module is directly fixed on lamp outer casing, dispelled the heat by lamp outer casing, improve heat dispersion.

2) LED module increases module cover in existing structure, plays fixed optics part on the one hand, on the other hand by using the good bolt of thermal conductivity or heat-conducting glue, heat is transmitted to the module cover in module front from the cooling base at the module back side.Because module cover is exposed in air, sufficient heat exchange can be carried out with air, thus good radiating effect can be played in the application scenario with closed shell light fixture.By increasing or change the shape of module cover, its heat-sinking capability can be strengthened further.

The beneficial effects of the utility model are, by the structure design that LED module is smooth, make it can reach by the different radiating fin of assembling the object changing heat radiation power neatly, and the shell of light fixture can be used to dispel the heat; By the application of module cover, the heat-sinking capability of module can be strengthened, and can use in the application scenario with closed shell light fixture.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the explosive view of LED module described in the utility model.In figure, (1) is module cover, and (2) are optical element, and (3) are LED lamp panel, and (4) are cooling base.In FIG, LED lamp panel (3) lower surface coating heat-conducting glue, and be fixed on cooling base (4) with screw, ensure contact surface good contact.Optical element (2) is fixed on cooling base (4) by 14 countersunk head screws by module cover (1).Wherein, module cover adopts the material that thermal conductivity factor is higher, as cast aluminium etc.Fixing screw can adopt stainless steel or copper, thus provides the good capacity of heat transmission.

In the embodiment shown in fig. 3, LED module cooling base does not add extra heat dissipation fin, in order to low power applications occasion.Fig. 4 and embodiment illustrated in fig. 5 respectively for middle power and high-power application scenario, corresponding, LED module cooling base is installed respectively the radiating fin (6) of alto radiating fin (5) and high height, thus meet corresponding cooling requirements flexibly.

In another embodiment shown in Fig. 6, LED module (7) is installed in the lamp interior that has flat interior surface and closed cavity, LED module (7) is contacted with each other by its smooth back structures and light fixture inner surface (8), and is dispelled the heat by light fixture radiating fin (9).Fig. 7 is the profile that in this embodiment of reflection, LED module contacts with light fixture inner surface.

The above, be only the embodiment that the utility model is general, and detailed description of the invention is based on the different embodiments under the utility model design.
