Abstract

The invention suggests a mobile telephone handset, which includes a battery; a housing containing the battery; a first set of terminals operatively joined to the battery and being in use adapted to be placed into contact with the circuitry of a mobile telephone handset for operation thereof; and a second set of terminals operatively joined to the battery and being in use adapted to be placed into contact with an illumination circuit provided in a cover of a mobile telephone handset.

Description

Illumination device.
FIELD OF INVENTION
The invention relates to an illumination device in particular for a mobile telephone handset.
BACKGROUND TO INVENTION
It invariably happens that a person requires an illumination means to indicate a remote object. In case of darkness it also may be necessary to illuminate an area or object. However, such illumination means (e.g. a torch) is not always available.
Mobile telephones ("handies" or cellphones, as they are called in some countries), or portable or cordless telephones are widely used all over the world. The number of such telephones is increasing at a tremendous rate. These telephones include, in addition to the electronic circuitry, a rechargeable battery. This battery often is charged in a motor vehicle while travelling along.
SOON (US Patent 5,901,206) suggested changing a portable telephone so as to act also as a flash light. This is done by accommodating a bulb and a reflector in the housing of a portable telephone, with a switch provided also in the housing and being adapted to switch the bulb on and off by way of electricity supplied from the battery of the portable telephone.
In US 4,618,917 LEE et al suggest a phone light accessory comprising a light producing element and a conductor element integrated into the hand set of a standard telephone. ARCHER (US 5,029,205) discloses a telephone handset that has a light bulb disposed on it and having a special switch for lighting automatically on using the telephone.
CERAMATE TECHNICAL (DE-GB 29819562) discloses a multi-function light indicator having a circuit for a mobile telephone device which includes a light. The arrangement is such that when the mobile telephone device receives a particular signal then the light is energized to be illuminated.
KNORR (DE GB 299 03 325) suggests a mobile telephone device with a battery and a light in the housing of the mobile telephone. The battery has contacts to be joined by way of a circuit to the light provided in the housing of the telephone.
HEE (US 6,045,235) discloses a mobile telephone device with a power supply unit which includes a flashlight. The power supply unit is fitted to the mobile telephone device for operating the flashlight. A separate housing is provided for the battery and the flashlight.
ATM-DENTAL-LABOR (PCT/EP99/01930) discloses a portable or mobile telephone device including a housing in which a power supply unit is provided. The telephone device has at least one additional device for carrying out an additional function. One of these functions is to illuminate a light. The light is provided in the housing of the telephone device.
DE 298 19 562 UI discloses a mobile telephone with a housing adapted to accommodate a light, which can be illuminated by operating a special switch.
In DE 299 03 325 UI a mobile telephone with a light integrated into the housing is shown. In all the above cases the housing of the cordless or mobile telephone has to be adapted to accommodate a light, circuitry leading to the handset battery is to be provided and a separate switch is to be accommodated on the housing. These suggestions can be incorporated in telephone handsets on production but in the case of existing handsets it is expensive and cumbersome as these have to be handed in to be converted by a person especially trained to effect the required alteration.

Referring to Figures 1 and 2, a cover for a mobile telephone handset, generally indicated by reference numeral 10, is shown. The cover 10 includes a cover housing 12 having a front edge 14 and a rear edge 16.
An illumination circuit 18 with a light emitting diode (LED) 20 and a switch 22 are located in the cover housing 12. The circuit 18 has terminals 24, 26 located on the underside 28 of the cover housing 12.
A battery device 30, including a battery housing 32 in which a battery 34 is located, is provided adjacent the underside 28 of the cover housing 12. The battery housing 32 may be attached, e.g. glued, to the underside 28 of the cover housing 12.
The battery device 30 has a first set of terminals 36, 38, which in use are adapted to be in contact with associated terminals (not shown) of a mobile telephone handset to which the cover 10 is to be fitted.
The battery device 32 further has a second set of terminals 40, 42, which in use are adapted to be in contact with the contacts 24, 26 of the circuit 18 in the cover housing 10.
In use the LED 20 is illuminated by depressing the switch 22.
When fitted to a mobile telephone hand set the battery device 30 is rechargable in conventional manner by insertion into a charging device or by inserting it into a specially designed charging device (not shown). The battery device 30 can also be recharged separately, i.e. when not fitted to a mobile handset housing, by way of a conventional charging device. In stead of using a switch 22, the LED 20 may be illuminated by operation of one of operational keys of a mobile telephone handset. The switch 22 therefore would be replaced by an electronic switch which is not shown as it is incorporated in the circuitry of the mobile telephone handset 10. Thus the mobile telephone handset 10 can be programmed such that any number of its operational keys are to be depressed to cause closure of the electronic switch resulting in current flow to the LED 20 from a circuit leading from the battery 32 to the LED 20 for illumination thereof.
The invention therefore provides a battery device provided with an LED 20, which can be used as a torch whilst simultaneously acting as the battery of a mobile telephone handset. Therefore no change to the handset housing nor to the circuitry of the mobile telephone handset is required.
Referring to Figures 4 to 9, a second embodiment of a mobile telephone handset in accordance with the invention is shown.
The mobile telephone handset, generally indicated by reference numeral 44, includes the following components:
46: a cover
48: an illumination device
50: an illumination element (LED)
52: a switch
54: a battery cover plate
56: aperture
58: aperture 60: a battery
62: contact
64: contact
66: conductor
68: conductor
70: contact
72: contact
74: battery housing
76: mobile telephone housing
78: locating recess.
On the underside 80 of the cover 46 contacts 82, 84 are located, which are connected in series to the switch 52 and the LED 50. In use these contacts 82, 84 are placed in contact with the contacts 62, 64 on the battery 60 through the apertures 56, 58 in the plate 54, and the contacts 70, 72 are in contact with the conventional circuitry (not shown) of the telephone handset 44.
In use the LED 50 is illuminated by depressing the switch 52.
When fitted to a mobile telephone hand set the battery 60 is rechargable in conventional manner by connection to a charging device (not shown).
Instead of using a switch 52, the LED 50 may be illuminated by operation of one of operational keys of a mobile telephone handset. The switch 52 therefore would be replaced by an electronic switch which is not shown as it is incorporated in the circuitry of the mobile telephone handset. Thus the mobile telephone handset can be programmed such that any number of its operational keys are to be depressed to cause closure of the electronic switch resulting in current flow to the LED 50 from a circuit leading from the battery 60 to the LED 50 for illumination thereof.
5 The invention therefore provides a cover with components to be fitted to a mobile telephone device provided with an LED 50, which can be used as a torch. Therefore no change to existing handset housings nor to the circuitry of an existing mobile telephone handset is required when fitting a device as illustrated in Figures 4 to 9.
10 Referring now to the Figures 10 to 15 of the drawings, a third embodiment of an illumination device for a mobile telephone handset in accordance with the invention is shown.
The device, generally indicated by reference numeral 86, includes the following:
88: a mobile telephone handset cover
15 90: first switch
92: second switch
94: illumination member (LED)
96: illumination member (laser light)
98: contact
20 100: contact
102: contact
104: contact 106: aperture
108: aperture
110: aperture
112: aperture
114: battery cover
116: battery
118: conductor
120: conductor
122: conductor
124: conductor
126: contact
128: contact
130: contact
132: contact.
The device, generally indicated by reference numeral 86, includes an indication or laser beam projecting part and an illumination part as will be described hereafter.
The illumination part for a mobile telephone handset includes a switch 90 connected to an LED light bulb 94 and provided on the cover 88. On the underside of the cover 88 contacts 98, 100 associated with the switch 90 are located. The battery cover plate 114 includes two spaced apart slots or apertures 106, 108.
On the battery 116 of the mobile telephone handset further elongated contacts 126, 128 are located, these being connected to the battery terminals (not shown) by means of conductors 118, 120.
In use the plate 114 is located on the battery 116 when accommodated in a mobile telephone handset (not shown) and thereafter the cover 88 is fitted onto the mobile telephone handset.
By depressing the switch 90 electrical current is aUowed to flow from the battery 116, along the conductors 118, 120 to the contacts 126, 128 and then through the contacts 98, 100 to the LED 94 for illumination thereof.
Similarly, current can be provided to the laser Ught 96 by depressing the switch 92 and aUowing current to flow from the battery 116 via the conductors 122, 124, the contacts 130, 132, the contacts 102, 104.
Instead of using the switches 90, 92 the LED 94 or the laser Ught 96 may be illuminated by operation of one of the operational keys of a mobile telephone handset. The switches 90, 92 therefore would be replaced by an electronic switch, which is not shown as it is incorporated in the circuitry of the mobile telephone handset. Thus the mobile telephone handset can be programmed such that any number of its operational keys are to be depressed to cause closure of the electronic switch resulting in current flow to the LED 94 or the laser Ught 96 from a circuit leading from the battery 116 to the LED 94 or the laser Ught 96 for illumination thereof.
This embodiment therefore provides the dual possibility of a laser beam projector which can be used as an indicator or a level, and a torch. List of Reference Numerals
