Technical field

This non-provisional is the number of patent application submitted on March 13rd, 2009 is 12/403,575, denomination of invention is the part continuation application of the U.S. Patent application of " Folding Rechargeable Worklight (Rechargeable folding portable lamp) ", and require the priority of above-mentioned U. S. application according to 35U.S.C. § 120, its full content is with in being incorporated herein completely see mode.

The present invention generally relates to electric lighting device, more specifically, relates to Portable work lamp, and this kind of working lamp has the integral flexible band with hook for being fixed on by portable lamp around object or object.

Background technology

Frequent existence utilizes portable lighting product to strengthen the needs of area illumination.Such portable lighting product is a portable lamp, and this kind of portable lamp can be used in little space and need in the various environment of light, include but not limited to the repairing environment of such as auto repair shop, architectural environment and other there is not the place of socket.These traditional portable lamps are often in holding or hang on the suitable form being elevated object.

Traditional is comprised incandescent portable lamp and fluorescence portable lamp by the portable lamp used.Some are provided to note when incandescent portable lamp is in for particular surroundings.Because portable lamp is generally used in zonule or hangs on the object be elevated, portable lamp may be collided or drop.When incandescent portable lamp is clashed into or drops, bulb and/or filament can easily break, thus make incandescent portable lamp cisco unity malfunction.In addition, if broken when bulb is in for flammability regime, hot filament may cause neighbouring combustible material burning, and initiation fire.

Although fluorescence portable lamp has more advantage than incandescent portable lamp, namely higher energy efficiency and reduction once drop is ignited the danger of combustible material, such as, but these fluorescence portable lamps also have the shortcoming being similar to incandescent portable lamp, have the Potential feasibility causing fire when ruptured.Although be reduced in the danger of the combustible material that to ignite when portable lamp drops or fallen down, but still be dangerous.The bulb of fluorescent lamp is better protected to prevent it from breaking, but still can break when colliding crust.Work fluorescent lamp bulb in thermode when being exposed in the process of dropping, may light near combustible material.

Recently, used LED portable lamp, this is some advantage owing to being better than incandescent portable lamp and fluorescence portable lamp.LED portable lamp is more suitable for after dropping, keep intact.In addition, the light source of LED portable lamp is compared with the light source of fluorescence portable lamp with white heat, works under low many operating temperatures.Therefore, when LED portable lamp drops and be broken, these low operating temperatures comparatively can not fire hazard.In addition, when comparing with fluorescence portable lamp with the white heat with equal illumination wattage, LED portable lamp is more energy-conservation.
