Abstract

A light bulb 4 that draws from the mains 1 is surrounded by photovoltaic cells 6 to generate power that is stored in a rechargeable battery 7. A trip device 3 and a battery limiter 8 switches the power from the mains to the battery when the battery becomes fully charged thus conserving energy via recycling unused illumination.

Description

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 [P1]. 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 a rechargeable battery.
This additional power [P2] is then utilized to light the same light bulb, alternately with the mains power source [P1]. This is done via a trip device that is governed by the battery charge limiter. The trip device is connected to both power sources, the mains [P1] and the battery [P2].
Once the battery's charge limiter rises to full [P2] , it activates a trip device, whereby the battery [P2] becomes the primary source of power. Once the power of the battery [P2] decreases (ie from 12v to 6v), the battery's charge limiter activates the trip device, 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 [P1].
Preferably, solar cells are protected by a protective shield.
Preferably, incorporates mirrors/reflectors to enhance/concentrate the performance of solar cells. -2-.
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 Show a Self Regenerating upright lamp according to this invention
Detailed Description:
Electric current travels from the mains (1), at 240v through to the converter (2), [This is optional & dependant on the bulbs used. In this example, a 240v-12v converter is used]. The electric current then travels through to a trip device (3), which is also connected to and controlled by the battery charge limiter (8). The electric current then travels through to the bulb (4), in this example a I 2v bulb, which then emits light (5).
Light emitted (5) by the bulb (4) is absorbed by photovoltaic [solar] cells (6), which surround the bulb (4), and which are wired to the battery (7) via diodes.
The photovoltaic [solar] cells (6) thus convert the emitted light (5) into power, in this example 12v, that is stored in a rechargeable battery (7).
Once the rechargeable battery ( 7) is full, the charge limiter (8) trips the tripping device (3), allowing the battery (7) to take over as the primary source of power.
Once the rechargeable battery ( 7) level decreases [ie, falls to a specified level, in this instance from 12v to 6v], the charge limiter (8) trips the tripping device (3), allowing the mains (1) to be the primary source of power.

Claims (4)

1) Recycling and utilising any form of light emitted from any source of power bar the sun, via the use of photovoltaic [solar] cells.
2) Recycling and utilising any form of light emitted from any source of power, bar the sun, according to claim 1, in which photovoltaic [solar] cells are incorporated into any light emitting appliance.
3) Recycling and utilising any form of light emitted from any source of power, bar the sun, according to claim 1, in which photovoltaic [solar] cells are incorporated into any shape of lamp, lampshades, uplights, light reflectors, light deflectors and all forms of light holders and bulbs.
4) Recycling and utilising any form of light emitted from any source of power, bar the sun, according to claim 1, in which photovoltaic [solar] cells are incorporated into any fixed or portable rechargeable unit [ie, battery recharges for mobiles, cameras and batteries].
