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).
Lighting design is not just an art; it is a science as well. Dark corners and dimly lit rooms are aesthetically displeasing, and people will generally steer away from them. Poor lighting can also diminish the color and texture of a living area, actually making it look worse. Alternately, intense lighting can wash out the colors of a room, and direct lighting often overpowers delicate wall textures andor décor.
Accent lighting is used mainly to highlight specific garden areas or objects, picking them out from the rest. You might want to use this type of lighting around a swimming pool or building or to light up aspects or features in your garden (e.g. a particularly attractive shrub or tree). General lighting (sometimes referred to as ambient light) fills in between task and accent lighting and is the sort of lighting you might choose to illuminate paths and work areas in your garden. For some areas you might want to use it in combination with accent lighting, switching between the two depending upon how you are using your garden. Down-lighting & up-lighting will, as the name suggests, cast light downwards or upwards. Wall lights are often used as down-lights to illuminate a flowerbed or a table that's adjacent to a wall. Up-lighting can be used to great effect in the garden under trees or statues to create special effects by profiling particular curves or angles.
