LED LIGHTS
LED, in full light-emitting diode, in electronics, a semiconductor device that emits infrared or visible light when charged with an electric current. Visible LEDs are used in many electronic devices as indicator lamps, in automobiles as rear-window and brake lights, and on billboards and signs as alphanumeric displays or even full-colour posters. Infrared LEDs are employed in autofocus cameras and television remote controls and also as light sources in fibre-optic telecommunication systems.
The material used most often in LEDs is gallium arsenide, though there are many variations on this basic compound, such as aluminum gallium arsenide or aluminum gallium indium phosphide.
The term diode refers to the twin-terminal structure of the light-emitting device. In a flashlight, for example, a wire filament is connected to a battery through two terminals, one (the anode) bearing the negative electric charge and the other (the cathode) bearing the positive charge

High-mast lighting is a tall pole with lighting attached to the top pointing towards the ground,usually but not always used to light a highway or recreational field. It is used at sites that require lighting over a large area. Some units have the lighting surrounded by a circular shield to prevent or reduce light pollution or light trespass from affecting neighborhoods adjacent highway.
LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and theresult is visible light. To prevent performance issues, the heat LEDs produce is absorbed into a heat sink.
A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes.The color of the light is determined by energy required for electrons to cross the band gap of the semiconductor.White light is obtained by using multiple semiconductors or a layer of the semiconductor device.
A solar lamp, also known as a solar light or solar lantern, is a lighting system composed of an LED lamp,solar panels, battery, charge controller and there may also be an inverter. The lamp operates on electricity from batteries, charged through the use of solar panel.Solar-powered household lighting can replace other light sources like candles or kerosene lamps.
