Abstract
The utility model discloses a light-emitting diode (LED) module, which comprises a radiator and an aluminum substrate fixed on the radiator. A plurality of LEDs are welded onto the aluminum substrate, a reflecting shield plate is fixed on the radiator, a plurality of through holes which are arranged corresponding to the LEDs are disposed on the reflecting shield plate, and a seal ring which surrounds the aluminum substrate is positioned between the reflecting shield plate and the radiator. The combined type LED module has simple structure, waterproof performance of the LED module is improved due to the adoption of the seal ring, and meanwhile the arrangement of a radiation fin enhances radiation performance of the whole LED module.
Description
Technical field
The utility model belongs to technical field of lighting fixtures, specifically relates to a kind of LED module.
Background technology
LED (Light Emitting Diode), promptly light emitting diode is a kind of solid-state semiconductor devices that electric energy can be converted into visible light, it can directly be converted into luminous energy to electricity.Along with the continuous development of LED technology, the range of application of LED more and more widely in recent years.The LED light fixture adopts the LED module to constitute mostly, because the LED module is non-watertight in the prior art, therefore the LED light fixture outside of being made up of the LED module needs to install waterproof glass or waterproof transparent plastic, just there is following shortcoming in this: one, because light transmittances such as glass or transparent plastic are low, cause the brightness of LED light fixture to reduce significantly; Two, the setting of glass or transparent plastic is unfavorable for the heat radiation of LED, can reduce the service life of LED light fixture; Three, also can increase the manufacturing cost of LED light fixture simultaneously.
Summary of the invention
The utility model provides a kind of LED module, and this modular structure is simple, and the setting of module internal sealing ring has improved the water resistance of LED module, does not influence the heat dispersion of module simultaneously.
A kind of LED module, comprise radiator and be fixed on aluminium base on the radiator, the some LED of welding on the aluminium base, be fixed with a reflecting shade plate on the described radiator, reflecting shade plate is provided with the through hole of some corresponding settings with LED, is provided with the sealing ring around aluminium base between reflecting shade plate and the radiator.
Described radiator is provided with some radiating fins back to a side of aluminium base, radiating fin the heat dispersion that has improved whole module is set, the quantity that radiating fin is provided with is generally determined according to actual needs.For further strengthening the heat dispersion of above-mentioned module, can on described radiating fin sidewall, be provided with some bar shaped burrs that are arranged in parallel, the bar shaped burr the area of dissipation that has increased radiating fin is set, thereby strengthened its heat dispersion.
Aluminium base and radiating fin are generally fixed by some screws, penetrate the radiating fin base plate for preventing screw, cause the entire module water resistance to reduce, and the radiating fin root of mounting screw place correspondence can be provided with the boss that is used for fixing aluminium base.
For ease of fixing of entire module, can one lampshade be set in the reflecting shade plate bottom, lampshade week is along being connected by screw with radiator and reflecting shade plate being fixed.
LED modular structure of the present utility model is simple, and the setting of sealing ring has improved the water resistance of LED module; Simultaneously radiating fin is provided with the thermal diffusivity that has improved the whole LED module.
Description of drawings
Fig. 1 is the structural representation of LED module of the present utility model;
Fig. 2 is the local structure for amplifying schematic diagram of the A part of LED module shown in Figure 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of LED module, comprise radiator 1 and be fixed on aluminium base 2 on the radiator 1, the some LED of welding on the aluminium base 2, be fixed with a reflecting shade plate 3 on the radiator 1, reflecting shade plate 3 is provided with the through hole of some corresponding settings with LED, is provided with the sealing ring 4 around aluminium base 2 between reflecting shade plate 3 and the radiator 1.
Radiator 1 is provided with 19 radiating fins 5 back to a side of aluminium base 2, and radiating fin 5 sidewalls are provided with some bar shaped burrs 10 that are arranged in parallel, with the area of dissipation of further enhancing radiating fin 5, thus the heat dispersion of increase entire module.Radiator 1 both sides are respectively equipped with a hold-down arm 8, and one of them hold-down arm 8 is provided with a water joint 7, are used for the connection of circuit in the module.Radiator 1 bottom surface is provided with four pairs of fixing screw holes, the radiating fin root that aligns with fixing screw hole is provided with boss formation aluminium base fixed bit, to improve the water resistance of entire heat dissipation fin, prevent that screw from penetrating the radiating fin base plate, cause the entire module water resistance to reduce.
Aluminium base 2 is provided with several LED, aluminium base 2 one sides be provided with eight with radiator 1 on the fixing fixing hole that aligns of sky of 8 screws, be used for fixing between aluminium base 2 and the radiator 1.Sealing ring 4 peripheries are provided with some through holes.Reflecting shade plate 3 bottom surfaces are provided with a lampshade 6, and 6 weeks of lampshade are along being connected by screw with radiator 1 and reflecting shade plate 3 being fixed.
LED module actual assembled process in the present embodiment is: at first according to actual needs some LED are fixed on the aluminium base 2, then aluminium base 2 are fixed away from the bottom surface of radiating fin 5 by hold-down screw and radiator 1; And then sealing ring 4, reflecting shade plate 3 put successively to aluminium base 2 corresponding positions, by lampshade 6 that radiator 1, aluminium base 2, sealing ring 4, reflecting shade plate 3 is fixing at last.
