LEDs produce light by the process of Electroluminescence. This is the phenomenon where by light is emitted from a material when an electrical current is passed through it. An LED chip is made from a material doped with 'impurities' to create a p-n junction between two types of semiconductors and electron holes. Electrons can only flow one way across the junction and as they do they fill electron holes causing their energy level drops and the release of photons (light).
LEDs are nothing like an incandescent light bulb. They have no glass bulb, there is no filament, and there is very little heat produced. This is because LEDs produce light in a wholly different manner. Rather than heat a filament like an incandescent bulb to produce light, which is by the way extremely inefficient, LEDs produce light through a process called electroluminescence. Rather than go into a long and drawn out technical explanation, it's enough to simply say that electrical power is fed through a small piece of semi-conducting material which then emits light energy. This process is extremely efficient, produces little heat, and is basically solid stated in operation, meaning there are no parts to simply burn up or wear out in a short period of time. At the most basic level, an LED is a diode, just like you'd find in a radio or your computer. They're efficient, compact, and powerful light sources that can operate for several years without fail.
There are many other decorative lamp fixtures for outdoor use such as underwater lamps that can be used for outdoor spaces with a pond or even a swimming pool and well lamps for those with an outdoor well. It is important to determine the type of lighting that will work well with your outdoor space first. Do initial planning before buying outdoor lamps. Find complementary outside wall lights and garden lighting that will help you achieve a nice diffused effect outdoors. But in addition to the style and the beauty of the lamps, you should also consider other factors such as energy efficiency, durability and over-all cost of the lighting fixture. Since they are placed outdoors, they should be strong enough to resist harsh weather.
