FIELD OF THE INVENTION

[0004] The present invention relates to a working lamp. More particularly, the invention relates to a working lamp for lightening things disposed in complicated or narrow places, for example, within an engine compartment or at the back of instruments of an automotive vehicle.

BACKGROUND OF THE INVENTION

[0005] Conventional working lamps comprise a transparent or translucent hollow cylindrical body having a handle, said cylindrical body being provided in the direction of the length thereof with a reflecting means, said cylindrical body being internally provided with a fluorescent light.

[0006] The conventional working lamps are large in size because the cylindrical body thereof is internally provided with a fluorescent light. For example, typical working lamps have an overall length of about 40 cm and the cylindrical body thereof has a diameter of about 5 cm. Thus, the conventional working lamps are too large to be used for lightening things disposed in complicated or narrow places, for example, within an engine compartment or at the back of instruments of an automotive vehicle.

BRIEF SUMMARY OF THE INVENTION

[0007] It is therefore an object of the invention to provide a working lamp, which has obviated the above-mentioned disadvantage of the prior art.

[0008] It is another object of the invention to provide a working lamp, which can be favorably used in complicated or narrow places.

[0009] These and other objects have been attained by a working lamp comprising a large number of light emitting diodes. The working lamp of the present invention comprises a transparent or translucent hollow cylindrical body having a handle, said cylindrical body being provided in the direction of the length thereof with a reflecting means, said cylindrical body being internally provided with a large number of light emitting diodes, said cylindrical body being provided on an outer surface thereof near said reflecting means with a permanent magnet.

[0010] The working lamp of the present invention lightens things by means of the light emitting diodes disposed within the transparent or translucent hollow cylindrical body either with the handle in hand or with the working lamp fixed near said things by means of the permanent magnet. Light emitted by the diodes passes through the cylindrical body either directly or after being reflected by the reflecting means, and reaches said things.

[0011] Since the working lamp of the present invention comprises a large number of light emitting diodes, which are very small in size, disposed within the transparent or translucent hollow cylindrical body, the working lamp can be made small in size to such an extent that the working lamp is capable of being carried or put in a pocket. Said large number of light emitting diodes lighten a wide area.
