Lighting 101: Science – Saving the Planet with LED
What is a light-emitting diode?
Light-emitting diodes (LEDs) are solid-state devices that convert electric energy into light. They are a directional light source, meaning they emit light in a specific direction, which essentially decreases the amount of wasted light. Even though some LEDs might appear “white,” there are no actual white LEDs. They naturally produce a blue light that can be combined with different phosphor materials to change the color of the light. The most common colors are amber, red, green and of course blue.
LEDs are the most energy efficient lighting technology on the market. Not only do they last 20 times longer than any other artificial light source, they also contain no mercury or hazardous waste – making them 100% recyclable.
Students won’t be exposed to hazardous waste materials due to their sustainable construction. LEDs that earn the ENERGY STAR seal of approval have been through rigorous testing to meet very strict requirements, making them the most energy efficient product options. TCP has many ENERGY STAR rated LED products that also qualify for various utility rebates.
Also unlike other artificial light sources, LEDs are 100% visually efficient, meaning they produce radiation only in the visible spectrum with no harmful UV or wasted infrared. They produce more lumens per watt than other light sources, which result in a high efficacy due to the fact that they use less power to produce the same light output. LEDs are predicted by the U.S. Department of Energy (DOE) to replace almost all artificial lighting in the United States by 2030.
Established in 1974 by the Warren-Alquist Act, the California Energy Commission (CEC) was formed as the state's primary energy policy and planning agency, committing to reducing energy costs and environmental impacts of energy use. Among ensuring the state has a safe...
Through various studies, light has been proven to impact the biological and psychological wellbeing of humans. It can affect our mood, sleep patterns, mental health and even our appetite.
To help save some money and energy this holiday season, consider upgrading to LED. LEDs have a long life and low energy consumption, making them the perfect present for your facility.
