Abstract
An electrical light that is powered by sound or pressure waves comprises an electromechanical housing consisting of an elastic membrane1 that enables vertical displacement of the light 4 from the external mounting 6. The displacement is converted from sound or pressure waves into electrical charge by the magnet and coil 7. The electrical charge generated is stored in a battery 2 within the unit. Controlling electronics 3 control the light 4 activation, charging of the battery 2 and manage the backup external power source 5.
Description
DESCRIPTION
Light powered by sound or pressure waves In areas where there is a requirement for light but also high sound pollution, such as a runway or busy road. This technology enables the sound waves or pressure waves to be converted into electrical power which can then be used to power the light, thus reducing energy usage and cost compared to a regular runway or streetlight.
This is a device that can convert sound into light it does this by having an electromechanical system that houses the light bulb. The electro mechanical system consists of a housing that can move relative to the external mounting (6) as shown in figure 1. The movement is caused by the soundwaves or pressure waves and this mechanical movement is translated into electrical energy using a device such as a magnet and conductive coil (7).
The lights electrical energy source comes from the battery (2) which is normally charged through the electromechanical device but can also be charged through an external power source (5), enabling the light to function when there is insufficient energy produced by the electromechanical device.
This feature also acts as a safety feature if there is a fault with the electromechanical device as the light can be externally powered as per a conventional light until the issue is resolved.
The way it works is there is a LED light (4) connected to the outer casing (6) of the device by an elastic membrane (1) which allows the light to move freely up and down with the sound or pressure waves. Connected to the underside of the light is an electromagnetic coil (7). The electromagnetic coil will be attached to the battery (2) via control electronics (3). The battery power supply is also connected through the control electronics to power the light. The way it converts the sound or pressure waves into electrical energy is when the sound waves hit the light it will then vibrate due to the elastic letting the light move vertically thus moving the magnet within the conductive coil therefore creating energy for the battery. This energy is then supplied from the battery to the light. There will be an extra external energy source (5) connected to the control electronics which can be used to charge the battery in the event that the device can not extract enough power from the sound or pressure waves, or there is a fault in the electromechanical device.
Claims (4)
- CLAIMS1. A light unit comprising of a LED light powered by electricity, a battery source, a flexible elastic membrane that allows the light to move vertically within the unit, a magnet and conductive coil that translate the vertical movement into electricity, and a controller electronics unit to control power delivery and power source for the light.
