Solar garden lighting is another cost-effective way to bring light to your flowering garden. Solar lights use a single battery composed of Nicam (nickel and cadmium) which is charged throughout the day by sunlight. At dusk, solar garden lights automatically turn on and at dawn, they automatically turn off. Again, solar garden lighting is available in a variety of sizes, shapes and colors. Colorful stings of lanterns, butterflies, stars, hummingbirds, and many other shapes can be found easily. Also solar statues, stakes, rocks and poles can be used to illuminate garden pathways.
Diodes allow current to flow only in one direction. Thereby, it stops the current coming in opposite direction. This diode emits light when current passes through it and that is why it is called as LED. There are no filaments to burn in LED and there is very little heat generated while lighting these bulbs. In conventional incandescent bulbs, much energy gets converted into heat which is of no use. It is the movement of electrons in the semiconductor material which illuminates the LED.
LED stands for light emitting diode. A diode is a device that allows electric current to flow in one direction but blocks it from flowing in the other. A good way to think of it is as a water valve for electricity. What separates an LED from just a regular diode is its ability to emit light when turned on. As you may already know the type of colour depends on the wavelength of light, with the red side of the spectrum being a longer wavelength and the violet side being shorter. An LED utilizes different compositions of materials to produce different wavelengths of light. This allows colours of impeccable purity and brilliance to be emitted, unlike incandescent bulbs which typically use a colour filter to produce the different hues. The actual process behind an LED light is far more complex than this as it involves both physics and chemistry to understand them fully. If you're looking for a more detailed explanation the team at London Lighting Hire is very knowledgeable in this department along with various other types of lighting so they'll surely have the answers you're looking for.
