PORTABLE LIGHT

Abstract

A portable light includes an extruded frame. The extruded frame includes two side plates, a top plate connected to the side plates, and a bottom plate connected to the side plates. A width between top portions of the side plates is less than a width between bottom portions of the side plates. The portable light further includes a housing, an LED module, a power device, and a manual switch including a pulling line extending out of the extruded frame. The portable light is used for shop illumination. A user can pull the pulling line to turn on or off the portable light. Notches of the extruded frame improve the heat dissipation. A protruded arced surface of the housing increases an illumination area of the portable light. Accordingly, the light emitted by the LED module is passing through the protruded arced surface to provide a uniform and larger illumination area.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a light, in particular to a portable light.

2. Description of the Prior Art

The conventional LED lights used in shops are adapted to be assembled on the ceiling or on the light-gauge steel frame of the building. The LED lights are easy for assembly and repairing, and the LED lights are energy-saving, high illumination, and in small volumes. Therefore, when LED lights are used to be assembled on the ceiling or on the light-gauge steel frame of the building, the illumination efficiency of the lights can be greatly improved and the energy consumption of the lights can be greatly reduced. The main component of the LED light, i.e., light-emitting diode (LED), is a new generation solid power source. The LEDs have advantages like, long lifetime, high efficiency in energy conservation, environmental-friendly, etc., and the LEDs are widely used in display and lighting.

The conventional LED light bars used in shops are provided for illumination with energy-saving purposes. However, the conventional LED light bars have dissipation problems. As a result, the so-called “LED light bars” are used with LEDs having lower powers. Moreover, conventional lights used in shops are mostly controlled by a switch assembled on the wall of the building to be turned on or turned off. Thus, Operations of the lights are not so convenient. Furthermore, some conventional lights are used with a single light tube (or a single light bulb) , and the illumination area is confined to a limited range. Therefore, when a larger area has to be illuminated, more lights have to be assembled. Accordingly, how to solve the problems is an issue.

SUMMARY OF THE INVENTION

In this embodiment, the portable light is used for shop illuminations, and the portable light is also called shop light. The structure of the extruded frame and the notches on the surface of the extruded frame allow the portable light to have great heat dissipation. When the LED module emits lights, though the heat generated by the LED module is gathered on the circuit board, such heat can be dissipated through the extruded frame. Therefore, the LED module does not have luminous attenuation due to being overheating.

In this embodiment, the pulling line is extending from the portable light, so that a user can pull the pulling line to turn on or turn off the portable light in a convenient manner. Conversely, it is understood that the conventional light can be turned on or turned off by the switch assembled on the wall, resulting in inconvenience for the user.

The LED module may be a high luminous-power LED module or a low luminous-power LED module, and the luminous power of the LED module may be up to 70 W. Furthermore, because the heat dissipation problem of the LED module is solved, the LED module may comprise LEDs with less number but higher luminous power to improve the illumination efficiency.

Moreover, the protruded arced surface of the housing increases an illumination area of the portable light. Accordingly, when the light emitted by the LED module is passing through the protruded arced surface, a uniform and larger illumination area can be provided. Additionally, the connectors of several portable lights can be connected with each other through wires, so that several portable lights can be connected with each other in series connection for further use.

Moreover, it is understood that the surface of the frame of a conventional light has extrusion marks, and the extrusion marks may be damaged or deformed easily when being forced. In one embodiment, the extruded frame of the portable light has a proper design in which the surface of the extruded frame provided with the notches. The notches form a decoration structure for the extruded frame without extrusion marks. Moreover, the notches allow the extruded frame to have improved structural strength and not to deform easily.

One embodiment of the present invention provides a portable light, wherein the portable light comprises an extruded frame. The extruded frame comprises two side plates, a top plate connected to top portions of the two side plates, and a bottom plate connected to bottom portions of the two side plates. A width between the top portions of the two side plates is less than a width between the bottom portions of the two side plates. The portable light further comprises a housing fixed on one side of the bottom plate, an LED module located in the extruded frame, a power device received in the extruded frame and electrically connected to the LED module, and a manual switch electrically connected to the LED module to control the LED module to be turned on or off. The manual switch comprises a pulling line extending out of the extruded frame.

In some embodiments, the bottom plate is recessed inwardly toward the receiving space, so that an area of the light illumination space increases. Two ends of the extruded frame are combined with side covers, and a surface of each of the side covers forms a connector.

In some embodiments, a surface of the extruded frame forms a plurality of notches.

In some embodiments, a protruding arced surface is formed on the housing to increase an illumination area of the portable light.

In some embodiments, two ends of the housing are provided with engaging grooves, and two ends of a side portion of the extruded frame are provided with engaging blocks for being engaged with the engaging grooves.

In some embodiments, a cross-sectional area of the extruded frame forms a rectangular structure with a width of the rectangular structure being gradually increasing from one of two opposite side of the rectangular structure to the other side of the rectangular structure.

In some embodiments, a plurality of hooks is assembled on the other side of the rectangular structure of the extruded frame.

The manual switch comprises a connection member, and the extruded frame comprises a positioning groove for positioning with the connection member.

In some embodiments, a luminous power of the LED module is 70 W.

These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.
