Waterproof light fixture

This creation relates to a waterproof luminaire, especially a waterproof luminaire that prevents moisture from entering and effectively achieves moisture resistance.

The light-emitting diode system is a solid-state semiconductor component, and the two carriers generated by the current through the diode are combined with each other to release the energy in the form of light, which has the advantages of light volume, fast reaction speed and no pollution, so that the light is emitted. The application field of diodes has gradually entered the various industrial circles. Although the initial development, it faces the bottleneck of insufficient brightness and low luminous efficiency, but the subsequent development of high-power LEDs solves the above problem of insufficient brightness. Luminous diodes are gradually entering the market of high-efficiency lighting sources, and there is a tendency to gradually replace traditional tungsten filament lamps, which is a potential product to replace traditional lighting in the future.

Although the light-emitting diode has the advantages of low power consumption, long component life, no need for warm-up time, and fast response speed, the general light-emitting diode emits lower brightness than a conventional light bulb or a lamp tube, so A high power light emitting diode is used as the illumination source. Although high-power LEDs can provide higher brightness, they will affect the efficiency of illumination due to temperature increase during continuous use. Therefore, how to make LED illumination have better illumination and prevent water. Gas infiltration to improve its service life is an important issue for the industry.

In view of this, the present invention is to provide a waterproof light fixture, especially a waterproof light fixture that can prevent moisture from entering and effectively achieve moisture-proof effect, and is its main purpose.

In order to achieve the above, the waterproof lamp of the present invention includes at least: a heat dissipation module, a light-emitting module, a lamp cover, a lamp holder, a screw base and a waterproof gasket, and the light-emitting module and the lamp cover are located on the heat-dissipating module, and The lamp holder and the screw base are located under the heat dissipation module, the heat dissipation module has a tubular body and a plurality of heat dissipation fins surrounding the tubular body, and the lamp holder has an insulative body and a driving circuit. The insulating body is provided with a receiving groove extending into the tubular body, and a gap is formed between the insulating body and the tubular body. The driving circuit is received in the receiving groove and electrically connected to the light emitting module.

Wherein, the waterproof gasket is sleeved outside the lamp holder, and the heat dissipation module presses the waterproof gasket on the lamp holder, and the waterproof gasket is provided with a tenon extending into the gap to prevent moisture from entering. Effectively achieve moisture-proof effect to ensure the operation of the drive circuit and the light-emitting module.

The sixth picture is a schematic diagram of the use of waterproof lamps in this creation.

The characteristics of this creation can be clearly understood by referring to the detailed description of the drawings and the examples.

For example, the first figure is an exploded view of the structure of the water-repellent lamp and the second figure is an exploded view of the overall structure of the water-repellent lamp. The waterproof lamp 1 of the present invention comprises at least the heat-dissipating module 10 and the light-emitting module 20 , lampshade 30, lamp holder 40, The spiral cap 50 and the waterproof gasket 60.

The heat dissipation module 10 has a tubular body 11 and a plurality of heat dissipation fins 12 surrounding the tubular body 11. The top surface of the tubular body 11 is provided with a heat dissipation plate 13.

The light-emitting module 20 is located on the heat dissipation plate 13 and has a circuit board 21 and a plurality of light-emitting elements 22 (which may be light-emitting diodes) located on the circuit board 21.

The lamp cover 30 is assembled on the heat dissipation module 10 and covers the light-emitting module 20; and the embodiment of the third embodiment shows that the heat dissipation module 10 and the lamp cover 30 have a plurality of The fixing holes 71 and 31 can be fixedly disposed, and the heat dissipation module 10 and the lamp cover 30 are assembled and positioned with each other.

The lamp holder 40 is located under the heat dissipation module 10 and has an insulative housing 41 and a driving circuit 42. The insulative housing 41 is provided with a receiving slot 43 extending into the tubular body 11 and the tubular body. A gap 44 is formed in the eleventh portions. As shown in the third and fourth figures, the driving circuit 42 is received in the accommodating groove 43 and electrically connected to the illuminating module 20.

The screw cap 50 is assembled to the bottom end of the insulative housing 41 of the socket and electrically connected to the driving circuit 42.

The waterproof gasket 60 is sleeved outside the socket 40 and opposite to the bottom end of the tubular body 11. The insulating body 41 of the socket is adjacent to the middle portion and is provided with an outwardly protruding ring wall surface 45.
