Abstract

A lamp or torch (10) comprises a housing (18) having an opening which is an interference fit with a battery (12). The housing has a bulb mounting (24) attached to two terminals (20, 22) not shown, which are positioned to make contact with terminals (14, 18) of the battery (12). <IMAGE>

Description

SPECIFICATION Improvements in or relating to lamps This invention relates to lamps, torches and night lights. Such devices are commonly used as sources of illumination and to indicate hazards.
The invention is particularly, though not exclusively concerned with road warning lamps. Such lamps commonly comprise a housing to contain a DC battery or batteries, a mounting for one or more light bulbs and a protective cover for the light source. The cover can be plain or any appropriate colour and the lamp is usually provided with a switch. In the case where the device is in the form of a torch there is usually a reflector to create a beam of light.
Road warning lamps are used extensively at and on the approach to roadworks and at the scenes of accidents. Lamps and torches of a similar construction are also used by the public services, local authorities and the gas, electricity and water boards. The lamps do not necesarily have a long useful life, mainly because of the nature of the environments in which they have to operate, but also due to other circumstances.
The present invention seeks to provide a lamp or torch of simple construction in which no protective case is provided for the DC power source.
Usually DC batteries have a relatively tough outer casing and the positive and negative terminals of the battery are located at the upper end of the battery. The present invention seeks to provide a lamp or torch housing which can be attached to the upper end of the battery, the housing being provided with terminals to engage the contacts on the battery. Accordingly the present invention provides a lamp or torch include a housing having a bulk mounting and two electrical terminals, the terminals being disposed so as to be aligned with the terminals of a battery, the housing having an opening so that the housing can be positioned on a battery with the terminals on the battery in contact with the terminals on the housing.
The torch can include a protective translucent clear or coloured cover so as to provide a protection for the light source.
The lamp or torch can also be provided with a reflector so as to provide a beam of light.
The present invention will now be more particularly described with reference to the accompanying drawings in which: Figure 1 is an elevation of one form of lamp or torch according to the present invention, Figure 2 is an elevation of the housing of the lamp or torch as shown in Figure 1, Figure 3 is a view on arrow A in Figure 2 and Figure 4 is a view on arrow B in Figure 2.
Referring to the drawings a lamp or torch 10 comprises a DC battery 12 having positive and negative terminals comprising spring contacts 14 and 16 respectively.
The lamp 10 also includes a housing 18 comprising a base 18A and a side wall 18B which is shaped to define an opening 18C corresponding to the external shape of the upper end of the battery 12. The size of the opening 18C is such that it is an interference fit with the upper end of the battery 12 so that when the housing 18 is pushed onto the battery the wall 18B grips the battery and the housing is retained on the battery.
On the under surface of the base 18A two circular plate contacts 20 and 22 are provided to correspond with the spring contacts 14 and 16 on the battery (see Figure 4).
A bulb mounting whether of the screw or bayonet type 24 is provided on a candle 26 which is attached to the baseplate 18A. The bulb fitting 24 is connected to the two contacts 20 and 22 in the usual way. A light source in the form of a tungsten filament bulb 28 is positioned in the mounting 24 and the candle 26 and the bulb are provided with a protective cover 30. The cover 30 can be of a clear transparent type or it can be of any suitable colour. The cover 30 can also incorporate a Fresnel lens and a reflector can be provided in the region of the light source so as to provide a beam of light if necessary.
It will be appreciated that when the housing 18 is positioned on the battery 12 and the contacts 14 and 16 engage the contacts 20 and 22 the light source 28 will be illuminated. The need for a relatively expensive casing for the battery will be avoided since the normal casing of the battery 12 should be sufficient for the life of the battery itself. Once the battery has been used the housing can be removed and used in conjunction with a fresh battery.
As the housing candle bulb and cover will be relatively inexpensive if the housing becomes damaged or lost it will be less expensive than the loss or damage of a lamp of the type incorporating a complete protective casing for the battery.
The housing can be provided with a positioning feature to ensure that the housing and battery are located correctly with reference to one another so that the contacts on the battery engage the contacts on the housing.
In the case where the contacts on the battery are of a different type to those illustrated, for example where the battery contacts are of the pin and dish type, the contacts on the housing can be of a correspondingly similar type.
If necessary the housing can be provided with a switch to make or break one of the electric leads from the contacts 20 and 22 to the lamp mounting 24.

Claims (6)

1 A lamp or torch including a housing having a bulb mounting and two electrical terminals, the terminals being disposed so as to be aligned with the terminals of a battery, the housing having an opening so that the housing can be positioned on a battery with the terminals on the battery in contact with the terminals on the housing.
2 A lamp or torch as claimed in claim 1 in which the opening in the housing for the battery is of a size to be an interference fit with the battery.
3 A lamp or torch as claimed in claim 1 or claim 2 in which the housing has a translucent cover.
4 A lamp or torch as claimed in any one of the preceeding claims in which the housing includes a reflector for a bulb.
5 A lamp or torch as claimed in any one of the preceeding claims in which the housing includes a switch arranged to make or break the electrical contact between one of the terminals and the bulb.
6 A lamp or torch constructed and arranged for use and operation substantially as herein described, and with reference to the accompanying drawings.
