“No other lighting technology (SSL / LED’s) offers as much potential to save energy and enhance the quality of our building environments, contributing to our nation’s energy and climate change solutions.”
-U.S. Department of Energy
LED’s have an expected life span of up to 100,000 hours!!
per Dan Keen, eHow Contributing Writer
For interior Lighting, it is recommended to calculate 10 hours per day for your standard 40 hour week, five days per week ~ which comes to 50 hours per week. Times that by 52 weeks year ~ that comes to savings for over 38 years!
For Exterior Lighting, is is recommended to calculate 12 hours per day, seven days per week ~ which comes to 84 hours per week. Times that by 52 weeks per year ~ that comes to savings for over 22 years!
Think of the Savings!!
What are LEDs?
A light-emitting diode (LED) is an electronic light source. LEDs are based on the semiconductor diode. When the diode is forward biased (switched on), electrons are able to recombine with holes and energy is released in the form of light. This effect is called electroluminescence and the color of the light is determined by the energy gap of the semiconductor. The LED is usually small in area (less than 1 mm2) with integrated optical components to shape its radiation pattern and assist in reflection.
In other words LEDs are the revolutionary way to directly convert electrical energy to visible light. This is unlike conventional light sources (light bulbs), which use extreme heat (wasted energy) to generate the light.
What does SSL mean?
Solid – State Lighting uses light-emitting diodes or “LEDs” for illumination. The term “solid-state” refers to the fact that the light in an LED is emitted from a solid object—a block of semiconductor—rather than from a vacuum or gas tube, as in the case of incandescent and fluorescent lighting.
Does LED Lighting eliminate light pollution?
Yes, due to Directional Illuminance, LED Lighting helps significantly decrease light pollution. This is done due to the fact that LED Lighting can be aimed in the desired direction, therefore eliminating the ‘glow’ of lighting which is caused by the old products which have been used to light parking lots, highways etc…
You can significantly help reduce this type of pollution by converting today!
What does Color / Temperature – or Kelvin mean?
An LED’s color temperature is measured in kelvins (K). Color temperatures greater than 5500K are “cool white” with a blue/green color. Color temperatures of 3000-5500K are “neutral white” while color temperatures of 2700–3000 K are “warm white” with a yellow/red color.
A common complaint regarding LED lighting is that it appears too ‘blue’. Some manufacturers of LED lighting solutions utilize the higher temperature LEDs (blue color) due to their high lumen per watt output.
Standard Smashray LED systems are produced in the ‘Neutral White’ color. This color temperature closely resembles the spectrum of natural daylight.
What is a LED Driver?
An LED driver is a self-contained power supply that has current and voltage outputs matched to the characteristics of the LED or array of LEDs.
What is the LED Light Engine?
An LED Light Engine is subsystem of an LED luminaire that contains one or more LED packages, or an LED array, or an LED module; and LED driver; electrical and mechanical interfaces; and an integral heat sink to provide thermal management. An LED light engine with a standard lamp base is an LED Lamp.
What is Luminance, Illuminance and Foot Candles?
Luminance is the intensity of light per unit area of its source. Luminance does not change with distance from the light. Illuminance, or Light Level, is the total luminous flux incident on a surface/work plane, per unit area. The work plane is where the most important tasks in the room or space are performed (ie. The desk surface in an office). Illuminance does change with distance from the light. When discussing light levels required in offices, classrooms, etc… at task level illuminance is the relevant term.
Illuminance is measured in foot candles (ftcd, fc, fcd) (or lux in the metric SI system). A foot candle is actually one lumen of light density per square foot, one lux is one lumen per square meter.
Why is Thermal Management is critical with LED lights?
While LED’s generate low amounts of heat into the room they are lighting (creating the benefit of lower air conditioning costs), the LED’s are actually emitting a large amount of heat off of the back of the conductive substrate they are mounted to. That substrate is mounted directly to a heat sink that serves the purpose of dissipating the heat away from the LED. Ensuring that the heat sink is designed and operates properly is imperative to the quality of LED lighting solutions. Excess heat directly affects both short-term and long-term LED performance. The short-term (reversible) effects are color shift and reduced light output while the long-term effect is accelerated lumen depreciation and thus shortened useful life.
What is a Conversion or Retrofit?
Conversion kits, also called Retrofits, are a quick and simple way to convert and upgrade your existing lighting fixtures to extremely energy efficient LED lighting. Maintaining the existing fixture minimizes time, cost and waste.
What are the real benefits of LED’s?
Energy savings – Most LED products save from 50% to 80% over existing technologies such as fluorescent and HID light bulbs.
Are LED’s good to use with Solar and Wind Energy?
Due to the low wattage draw that LED’s use, it is an extremely good light source to use when using Solar, Wind Turbines or other ‘alternative’ energy sources.
What is Mercury?
Mercury is a highly toxic metal that is harmful to both humans and wildlife. Exposure to even small amounts of mercury, over a long period of time, may cause negative health effects including damage to the brain, kidneys and lungs.
Unborn and young children are especially susceptible to mercury exposure because their nervous systems are still developing. Whether it is absorbed through the skin, inhaled or ingested, exposure to mercury should be taken very seriously.
Mercury is classified as a toxic substance.
What types of light sources contain mercury?
Mercury is present in several types of conventional lighting including:
- Fluorescent and compact fluorescent bulbs.
- High intensity discharge bulbs (HID). The following are HID bulbs:
- Mercury vapor
- Metal halide
- High pressure sodium
What is RoHS?
RoHS is the acronym for Restriction of Hazardous Substances. The substances banned under RoHS are lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE). All of LED products and processes are RoHS compliant.
Do LED’s contain Mercury or Lead?
No! LED’s do not contain Mercury or Lead. Therefore, disposal of LEDs does not contaminate the environment and poison our environment and wildlife.
How long of a Life is expected with LED Lights?
LED’s have an exceptional life expectancy of 100,000+ hours. Due to its Long life – eliminates replacement and maintenance costs throughout its life.
How does LED lighting help lower energy costs?
Just the shear fact that they have such a low Wattage use lowers your energy costs. But also, due to their minimal heat generation, LED Lighting helps reduces air conditioning costs as well, saving you a ‘collateral’ savings advantage.
Is the Life span effected by ‘on/off’ usage?
No, the Life span is not affected by “on/off” usage. The life of conventional light sources is diminished each time they are cycled on and off, but this is not the case with LEDs, which see no reduction in life due to cycling.
Do LED lighting have an Instant ‘On’?
Yes, LED Lighting do have an instant On. LEDs turn on instantly and do not require a ‘start up’ time. HID light bulbs require a start up time of up to several minutes. This is a significant benefit for industrial applications where delayed ‘on’ times can cause major disruption.
