INTRODUCTION OF LED
Light-emitting diodes (LEDs) are a relatively old technology (1960s) that has advanced from use in numeric displays and indicator lights to a range of new and potential new applications, including exit signs, accent lights, task lights, traffic lights, signage, cove lighting, wall sconces, outdoor lighting and decorative lighting.
LEDs offer benefits such as small size, long lamp life, low heat output, energy savings and durability. They also allow extraordinary design flexibility in color changing, dimming and distribution by combining these small units into desired shapes, colors, sizes and lumen packages. Currently, relatively low overall light output, poor color rendering and questions about advertised service life may indicate that LEDs, while very useful in many applications, are not yet ready for "prime time" in some architectural applications. Notably promising current applications include retail display, colored lighting, tight spaces, areas that require low light levels, exterior lighting and applications where the integration of light sources and architectural elements is critical.
LEDs currently dominate the exit sign market and many cities have adopted them as a replacement for incandescent lamps in traffic signals. In the architectural market, the development of a visible/white light LED has awakened lighting designers to new possibilities with this light source. White light LEDs, however, currently do not produce enough lumen output to make them competitive with many general light sources.
Characteristics
LEDs are solid state semiconductor devices. LED illumination is achieved when a semiconductor crystal is excited so that it directly produces visible light in a desired wavelength range (color). LED units are small, typically 3~5mm. And several shapes of LED are available now in the market.
Color
The color composition of the light being emitted by the LED is based on the chemical composition of the material being excited. LEDs are available that can produce colors including white, deep blue, blue, green, yellow, amber, orange, red, bright red and deep red.
Efficacy
LEDs are low-voltage(2V~3.2V), low-current(20mA) devices and efficient light sources. For red, amber, yellow, green and blue LEDs, new materials have been developed that are more efficient than traditional materials, producing efficacies (lumens per watt) greater than incandescent lamps and rivaling fluorescent lamps. Besides, LED have low heat emitting,
which is about half as efficient as an equivalent tungsten-filament lamp.
Long lifetime and durable
Under proper situation, such satisfied voltage,current as well environment,
the lifetime of LED is up to 100,000 hours.
LED are made from non-toxic material, which can be recycled and hardly to
be Damaged, unlike the traditional lamp made of glass.
No UV Emissions/Little Infrared
LEDs produce no UV radiation and little heat, making them ideal for illuminating objects, such as works of art, that are sensitive to UV light.
Other Benefits
The other benefits of LEDs include:
Lights instantly Can be easily dimmed Silent operation Low-voltage power supply (increased safety) With more and more competitive price as well wider application of LED, we are convinced that LED will be an idea and important light source in this century. And we are also very glad to introduce our products, such as LED Softlight, LED Light String, LED Neon Tube, LED Lawn Light ....etc. many series items, to all over the world. |
