Abstract

A lamp device has a light source (2) powered by an internal rechargeable power source. An integral three pin plug device (6) extends from the rear of the device and allows the device to be connected directly to a mains socket for recharging of the rechargeable power source via a built in transformer and rectifier. An on/off switch (9) and a fuse (10) are also fitted to the device. <IMAGE>

Description

SPECIFICATION Rechargeable lamp This invention relates to a rechargeable lamp device.
Conventionally portable torches and the like are generally powered by one or more disposable dry cell batteries. Alternatively rechargeable batteries may be used which can, when exhausted, be removed and fitted to a separate charging device to be recharged.
Both of these types are inconvenient to use as the batteries must be periodically removed for recharging or replacement.
According to the present invention there is provided a lamp device comprising a light source, an integral rechargeable power source for the light source and means for connecting the rechargeable power source to an external power supply for recharging of said rechargeable power source.
Preferably, the means for connecting the rechargeable power source to an external power supply is a pin arrangement integral with the device for engagement with a mains supply socket.
Preferably also, the pin arrangement comprises three pins for engagement with a three pin mains supply socket.
Preferably also, the device includes a transformer and rectifier to convert the mains AC power supply to a DC power supply for the rechargeable power source.
An on/off switch may be included on the device together with a fuse for the mains power supply.
The device may also include more than one light source.
An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a front view of a lamp device in accordance with the present invention; Figure 2 is a side view of the lamp device of Fig. 1; Figure 3 is a rear view of the lamp device of Fig. 1; and Figure 4 is a perspective front view of the lamp device of Fig. 1.
Referring to the drawings, a lamp device comprises a plastics material case 1. A pair of bulbs 2 and 3 are mounted in the casing behind lenses 4 and 5. A three pin plug device 6 extends from the rear of the case 1.
The rear panel 7 of the case 1 is removable by way of screws 8 to allow access to the interior of the device for maintenance, for example to replace the bulbs 2 and 3. An on/off switch 9 is fitted through the rear panel 7 and a fuse 10 is fitted to the plug device 6. The plug device 6 is connected to a rechargeable battery by a transformer and rectifier.
In use the rechargeable battery provides power for the bulbs 2 and 3 as in a conventional battery powered lamp or torch under the control of the on/off switch 9.
When the battery becomes exhausted the plug device 6 allows the lamp to be connected to a conventional wall socket mains power supply. A transformer and rectifier device steps down the mains supply voltage and converts it from AC to DC to charge the battery. Once the battery has been charged the lamp can be removed from the mains power supply and either used immediately or stored in readiness for use.
Modifications and improvements may be made without departing from the scope of the invention.
1. A lamp device comprising a light source, an integral rechargeable power source for the light source and means for connecting the rechargeable power source to an external power supply for recharging of said rechargeable power source.
2. A lamp device as claimed in Claim 1, wherein the means for connecting the rechargeable power source to an external power supply is a pin arrangement integral with the device for engagement with a mains supply socket.
3. A lamp device as claimed in Claim 2, wherein the pin arrangement comprises three pins for engagement with a three pin mains supply socket.
4. A lamp device as claimed in any one of the preceding Claims, and including a transformer and rectifier to convert the mains AC power supply to a DC power supply for the rechargeable power source.
5. A lamp device as claimed in any one of the preceding Claims, and including an on/off switch and fuse in the supply to the rechargeable power source.
6. A lamp device as claimed in any one of the preceding Claims, wherein a plurality of light sources are included.
7. A lamp device substantially as hereinbefore described and with reference to the accompanying drawings.
