LED Lighting

A light-emitting-diode lamp is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. Since the light output of individual light-emitting diodes is small compared to incandescent and compact fluorescent lamps, multiple diodes are used together. LED lamps can be made interchangeable with other types. Most LED lights must also include internal circuits to operate from standard AC voltage. LED lights offer long life and high efficiency, but initial costs are higher than those of fluorescent lamps.


LED lamps are used for both general lighting and special purpose lighting. Where colored light is required, LEDs come in multiple colors, which are produced without the need for filters. This improves the energy efficiency over a white light source that generates all colors of light then discards some of the visible energy in a filter.


White-light light-emitting diode lamps have the characteristics of long life expectancy and relatively low energy consumption. The LED sources are compact, which gives flexibility in designing lighting fixtures and good control over the distribution of light with small reflectors or lenses. Due to the small size of LEDs, control of the spatial distribution of illumination is extremely flexible and the light output and spatial distribution of an LED array can be controlled without efficiency loss.


LED lamps have no glass tubes to break, and their internal parts are rigidly supported, making them resistant to vibration and impact. With proper driver electronics design, an LED lamp can be made dimmable over a wide range; there is no minimum current needed to sustain lamp operation. LEDs using the color-mixing principle can produce a wide range of colors by changing the proportions of light generated in each primary color. This allows full color mixing in lamps with LEDs of different colors. LED lamps contain no mercury. Why not as a starting point, drop into one of our branches and replace your recessed downlights in your kitchen with some LED lamps. The more of them you buy the cheaper the per unit cost will be, and the lower your electricity bill will become. By working together we will help reduce our planets carbon footprint !
