Dorm Room Lighting Essentials: Back to School

Back to School Written with PenIt is that time of year again; back-to-school time. From now until mid-September, students are heading to college dorm rooms all across the country. In addition to dorm room rugs, televisions, video games, and computers, lighting is an essential addition to any dorm room’s décor. “Institutional dorm lighting is not exactly the most cheerful. Putting a few better light sources in your room can make the space much more pleasant,” says Naomi Rockler-Gladen of

As we all know, school, work, social, and study schedules rarely match up between roommates. One potential area for disagreement is over the room’s lights. Either they are kept on most of the night or are turned on suddenly while one roommate is sleeping. However, wireless, energy-efficient LED lighting is a quick and inexpensive solution to help avoid these potential dorm room disasters.

Cavity Design Increases OLED Light Output

A couple of months ago we posted an article to the Pegasus Associates Lighting website that listed the 10 things to know about LED lighting. Number nine on our list of 10 things to know was OLED.

9. OLED An OLED is an organic light emitting diode.  It is an LED that also contains carbon.  OLEDs are generally manufactured as flexible lightweight sheets.  Today, OLEDs operate at significantly lower efficiency than inorganic (crystalline) LEDs.  OLEDs typically generate less light per area than inorganic, solid state LEDs, which are usually designed for use as point-light sources., LED Lighting: 10 Things to Know

Today I learned that scientists from the independent Stanford Research Institute (SRI) found an innovative design to increase light output and energy efficiency of OLEDs. The answer is cavities. The device that they produced is called, watch out for another acronym, COLED. Yes, the C stands for cavity.

LEDs Might Lead a Lighting Revolution in Five Years

In five years we may just see a revolution in residential and office lighting led by LEDs manufactured with gallium nitride, according to Professor Colin Humphreys of Cambridge University. Gallium nitride LED lighting produces a brilliant light and could cut electricity consumption by approximately 75% in developed countries. This reduction would have the added benefit of creating substantial cuts in carbon dioxide emissions from power stations and help to preserve our fossil fuel reserves.

Gallium nitride, or GaN, is a semiconductor material that is considered by many to be the next important semiconductor after silicon.  It is a brilliant light emitter able to operate at high temperatures. GaN is used to create devices with small physical volume that produce high output power.
