Light Emitting Diode (LED)

Light Emitting Diode (LED) Lamps represent new technology with expanding applications, particularly in color and specialty applications.

Festival Lighting LED lights can be direct replacements for colored lamps. The Festival lights can replace a typical 60-watt painted incandescent bulb with only 2.5 watts of power. Imagine using 1000 lamps in an installation.

Cove and Marquee Lighting LED lamps can be for both cove light and marquee lighting applications. For cove applications, the even light distribution and low heat generation make them ideal for placement in those hard to get to places.

Festoon Lighting such as to highlight the outline of a building or bridge. A typical installation would use hundreds to thousands of 25-60 Watt lamps. Festival LED lamps are direct replacements.

Important Advantages include:

• Power Savings - A 1000 bulb installation with 25-60 watt lamps would require 25-60 kW of power over large cables. With Festoon LED lamps, the power requirements lower to only 2.5 kW.and much smaller wiring.



• Better visual effects - Festoon lamps are for decoration and are point source devices meant to be viewed. With painted incandescent lamps, light escapes from the back of the globe as well as the front. This lowers the contrast, making it harder to see. Also, incandescent painted lamps have a tendency to light up the inside of people's offices, a source of complaints from the building occupants. As LED lamps are point sources and do not "paint" the rear surface with light and greatly increases the contrast and overcomes the problem of lighting up the occupant's space.



• Visibility during the day - Painted lamps must be on during the day to see the colors because the lamps look black when turned off. Festoon LED colored globes glow in its original color, activated by the sun's Ultra Violet rays. Operators may choose to power down the lamps during the day and yet still see the colors, adding more energy cost savings.



• Low heat generation - LED lamps produce very little heat, thus reducing the air conditioning load and associated electric bills. This also reduces the fire hazards involved with flammable material touching the surfaces of the lamps.

Can LED lamps replace ordinary light bulbs? It depends on what you want!

White Light - It would seem as if the LED lamp would work in place of a conventional light bulb, yet LEDs are still a long way away from general lighting (at least in terms of affordability). For example, a 100 watt light bulb costs less than a dollar and puts out 100 x 12 lumens or 1200 lumens for less than one dollar. A great number of LEDs would be needed to achieve the same lumen output level making the costs quite prohibitive.

Colored or Filtered Light - Colored incandescent lamps filter the white light to the single color you see. The filtering greatly reduces the efficiency to only a few lumens per watt. Colored LEDs produce light in a single color and at higher efficiencies than white LEDs. To get around this issue with white LEDs the lamps are blue LEDs with a yellow phosphor coating to produce white light, making them much more efficient and therefore requiring less LEDs to do the job. The job in this case would be decorative lighting, landscape lighting, accent lighting, wall washing, and special effects. These applications are the most suitable for LEDs in lighting today. LED's as spot lamps concentrate the light in a smaller area without any significant losses in lumens per watt. Smaller number of LEDs, low power consumption, low heat generation, and much longer life make them competitive in many applications.
