Abstract

A rechargeable lamp comprises at least one light bulb <B>4</B> surrounded by a plurality of photovoltaic (solar) cells <B>6</B> which generate an additional power source that is stored in at least one rechargeable battery <B>7</B>. Once the at least one battery <B>7</B> is full a limiter <B>8</B> trips a trip device <B>3</B> so that the at least one battery <B>7</B> powers the lamp. When the power output of the batteries <B>7</B> drops below a predetermined value the trip device <B>3</B> switches to mains power <B>1</B> via a converter <B>2</B>, alternating between the two sources of power and thereby conserving energy.

DESCRIPTION
Title: Self Regenerating Light
Background:
This invention relates to recycling the existing energy that is being used.
When a light is switched on, it is using power from the mains [P 1]. This power [P1] is used solely to light the bulb and nothing else.
Statement of Invention:
To recycle this existing power source, we propose the use of photovoltaic [solar] cells, which would surround the light source.
Surrounding the light source with photovoltaic [solar] cells means that, the same power that is solely used to emit light is also being used to generate an additional power source [P2]. This additional power [P2] is stored in rechargeable battery or batteries or power the lamp.
This additional power [P2] is then utilized to light the same light bulb or bulbs, alternately with the mains power source [P1]. This is done via trip device or trip devices that is/are governed by the battery charge limiter/limiters. The trip device or devices is/are connected to both power sources, the mains [P11 and the battery or batteries [P2].
Once the battery's charge limiter or limiters rises to full [P2] , it activates the trip device or devices, whereby the battery or batteries [P2] becomes the primary source of power. Once the power of the battery or batteries [P2] decreases (ie from 12v to 6v), the battery's charge limiter or limiters activates the trip device or devices, whereby the mains [P1] becomes the primary source of power.
Advantages: This invention, by recycling and reusing the main source of power, will conserve energy.
Preferably, has a counter, indicating the number of units used from the mains [P 1].
Preferably, solar cells are protected by a protective shield.
Preferably, incorporates mirrors/reflectors to enhance/concentrate the performance of solar cells.
Preferably, when two or more batteries are being used, the battery or batteries not giving power to the bulb or bulbs is/are being charged via the photovoltaic [solar] cells.
DRAWINGS
An example of the invention will now be described by referring to the accompanying drawings:-Figure 1 Shows a standard upright lamp; and Figure 2 Shows a Self Regenerating upright lamp according to this invention using one battery; and Figure 3 Shows a Self Regenerating upright lamp according to this invention using two batteries
Detailed Description:
Electric current travels from the mains (I), at 240v through to the converter/converters (2), [This is optional & dependant on the bulbs used. In this example, a 240v-1 2v converter is used]. The electric current then travels through to a trip device or devices (3), which is also connected to and controlled by the battery charge limiter or limiters ( 8). The electric current then travels through to the bulb or bulbs (4), in this example a 12v bulb, which then emits light ( 5).
Light emitted ( 5) by the bulb or bulbs (4) is absorbed by photovoltaic [solar] cells ( 6), which surround the bulb or bulbs ( 4), and which are wired to the battery or batteries ( 7) via diodes. The photovoltaic [solar] cells ( 6) thus convert the emitted light ( 5) into power, in this example l2v, that is stored in a rechargeable battery or batteries ( 7) after passing through a charge regulator or regulators (9).
Once the rechargeable battery or batteries ( 7) is/are full, the charge limiter or limiters ( 8) trips the tripping device or devices (3), allowing the battery or batteries ( 7) to take over as the primary source of power.
Once the rechargeable battery or batteries ( 7) level decreases [ie, falls to a specified level, in this instance from 12v to 6v], the charge limiter or limiters ( 8) trips the tripping device or devices ( 3), allowing the mains (1) to be the primary source of power.
In the instance of two of more batteries being used, the electric current travels from the mains (1), at 240v, through to the converter/converters ( 2) and through a charge limiter or limiters ( 8) and tripping device or devices ( 3), or as many of each needed to determine which battery or batteries ( 7) will take over from the mains supply (1).
By using two or more batteries ( 7), we would increase the energy saved from the mains supply ( I).

Claims (1)
