Description

Technical field

[0001] The utility model relates to the technical field of lamps, and in particular to a waterproof portable LED work lamp used in work places such as construction sites, mines, docks, workshops, etc. [Background Technology]

[0002] As society continues to progress and develop, and with it, consumers' living standards continue to improve. Simultaneously, a wide variety of lighting fixtures have entered various areas of life, work, and entertainment. However, most existing work lamps include a main body for emitting light and a handle for carrying.

[0003] Since there is some gap between the LED lamp bead lighting part inside the lamp body and the outer part of the lamp body, it is easy for external moisture, dust and floating debris to enter the LED lamp bead lighting part inside the lamp body. After using it for a period of time, over time, some dust or moisture will accumulate on the surface of the electronic components on the surface of the lamp board inside the lamp body, thereby causing the surface of the exposed metal welding feet of the electronic components to be oxidized. In severe cases, it will cause a short circuit between the electronic components soldered on the lamp main board, and the electronic components will be burned, thereby shortening the service life of the work lamp. [Utility Model Content]

[0004] In view of this, the technical problem to be solved by the present invention is to provide a waterproof portable LED work light with an extended service life. The LED work light can avoid the short circuit and burning of the lamp main board caused by long-term accumulation of dust and moisture.

[0005] To solve the above technical problems, the technical solution in the present invention provides a waterproof portable LED work lamp, which includes a lamp body, a plastic handle arranged at the upper end of the lamp body, and a power supply device arranged at the lower end of the lamp body; the lamp body includes a lamp base placed at the lower end, a lamp cover seat placed at the upper end, a plurality of threaded rods installed around the lamp base and the lamp cover seat, a transparent cover installed between the lamp base and the lamp cover seat and located inside the plurality of threaded rods, an upper waterproof gasket installed at the upper end of the transparent cover, a lower waterproof gasket installed at the lower end of the transparent cover, and a heat dissipation lighting component installed inside the transparent cover; the upper waterproof gasket and the lower waterproof gasket are connected and fixed to the end surface of the transparent cover by a transparent colloid, so that the heat dissipation lighting component is placed inside the enclosed space inside the transparent cover.

[0006] The heat dissipation lighting assembly includes a heat dissipation assembly placed in a central position, side light panels installed around the heat dissipation assembly, a plurality of LED lamp beads welded on the side light panels, and a plurality of side screws used to fix the side light panels to the surface of the heat dissipation assembly.

[0007] The heat dissipation component includes a heat dissipation body, which includes a plurality of heat dissipation units, and the plurality of heat dissipation units are arranged in a cylindrical shape in a circular array; the heat dissipation units are formed by an aluminum profile or an extension of an aluminum profile material with a pattern in a transverse cross section and an integrated molding.

[0008] The plastic hand piece includes a U-shaped hand handle placed on the lamp cover seat, nuts installed at both ends of the hand handle, screws for fixing the hand handle and the nuts on the lamp cover seat, and a waterproof plug.

[0009] The power supply device includes a power box placed on the bottom of the lamp base, a waterproof connector installed on one side of the power box, a plug wire installed on the waterproof connector, a plug connected to the plug wire, a power board installed at the bottom of the power box, a power module welded on the power board, a fan welded at the center of the power board, and a waterproof connector installed on the upper end of the fan.

[0010] The beneficial technical effects of the present utility model are as follows: the lamp body includes a lamp base placed at the lower end, a lamp cover seat placed at the upper end, a plurality of threaded rods installed around the lamp base and the lamp cover seat, a transparent cover installed between the lamp base and the lamp cover seat and located inside the plurality of threaded rods, an upper waterproof gasket installed at the upper end of the transparent cover, a lower waterproof gasket installed at the lower end of the transparent cover, and a heat dissipation lighting component installed inside the transparent cover.

[0011] Because the upper waterproof gasket is placed on the upper end surface of the transparent cover and the lower waterproof gasket is placed on the lower end of the transparent cover, and the upper and lower waterproof gaskets are respectively connected and fixed to the end surfaces of the transparent cover via a transparent colloid, the heat dissipation lighting assembly is placed within the enclosed space within the transparent cover, and the multiple LED lamp beads welded to the side light board can be used in the enclosed space, preventing the LED lamp beads from being exposed to dust and moisture for a long time, which is conducive to extending the service life of the work light. At the same time, it also fundamentally solves the problem of short circuit and burning of the lamp main board caused by long-term accumulation of dust and moisture.
