LED TRI-PROOF LAMP

Description

Field of the Invention

[0001] The present invention relates to a lamp, particularly to a waterproof, moisture-proof and dustproof LED lamp.

Description of the Prior Art

[0002] An existing waterproof, moisture-proof and dustproof lamp generally comprises a lamp body formed of a lamp base and a lampshade connected with each other, and an illuminant being disposed within the lamp body. The illuminant is generally a fluorescent lamp. A reflector is to be disposed between the illuminant and the lamp base to reflect light.

[0003] With the increasing development of light sources, LED has become the most promising new product. Compared with filament lamps and fluorescent lamps, an LED has the following advantages: small size; combination of a plurality of LEDs or various types of LEDs; low heat, basically free of heat radiation; low power consumption, to be started at low voltage and low current; long service life, over ten thousand hours of working time; fast response, operable at a high frequency; environmentally friendly, and shock, impact and breakage resistance; recyclable as waste, without pollution; planar packaging, and easy development into small, light and compact products.

[0004] However, if LEDs are used as the light source of a lamp, a power supply drive module for driving the LED is to be provided additionally. The power supply drive module will emit much heat when in service, so it is disadvantageous for heat dissipation if both the LED light source and the power supply drive module are disposed within a lamp body. Therefore, the existing waterproof, moisture-proof and dustproof lamps rarely use LEDs as the light source.

[0005] US Patent Publication No. US-2012/0188766 discloses an LED lamp including a heat dissipating base, an LED module, a hood and a sealant. The heat dissipating base has a mount board including a first surface and a second surface. The first and second surfaces are provided with an annular trough and fins, respectively. The LED module is fixed on the mount board and surrounded by the annular trough. The hood is formed with a flange which is embedded into the annular trough to cloak the LED module. The sealant is filled in the annular trough to seal up.

[0006] Chinese Patent Publication No. CN-101943339 discloses an LED illuminating lamp comprising a heat radiation base, a fixed support, a power supply box, a light enhancement shield, a light transmission shield and a fixed end cover, wherein the heat radiation base has a containing space; a dovetail groove and a T-shaped groove are arranged outside the heat radiation base; a positioning groove is arranged on the inner wall surface of the heat radiation base; a T-shaped block is arranged on the fixed support and inserted along the T-shaped groove; the fixed support is fixedly connected with the heat radiation base through screws; a dovetail inclined angle is arranged in the power supply box and inserted along the dovetail groove; the power supply box is fixedly connected with the heat radiation base through the screws; the light enhancement shield is arranged in the containing space; a plurality of grid grooves are arranged on the light enhancement shield; LED lamp bodies and lenses are arranged in the grid grooves; a positioning pillar is arranged on the fixed end cover and inserted along the positioning groove; and the fixed end cover is fixedly connected with the heat radiation base through the screws.

[0007] US Patent Publication No. US-2011/0317420 discloses a lighting device including a light source having a plurality of light emitting diodes (LED), and a housing having a base to support the light source. The housing has a plurality of cooling fins that extend away from the base. A vertical wall vertically protrudes inside edges of the base. The light source is provided in a space that is surrounded by the vertical wall, and includes the plurality of LEDs, which are mounted on a printed circuit board (PCB). The PCB is located at a center of a recessed portion that is surrounded by the vertical wall. A sealer groove is formed at a bottom of the recessed portion so as to surround the PCB, a sealer being provided in the sealer groove. The window is provided on the base to cover the light source. The window is attached by screws to a bottom of the recessed portion outside of the sealer in tight contact with the sealer.
