LED Basics

What is an LED?
An LED (light-emitting diode) is a semiconductor chip that generates light when a current is applied. The chips are assembled in a structure that supports and protects the chips and electrical connections. The structure as a whole is an LED package. This type of technology is extremely energy efficient compared to traditional lighting methods such as incandescent. There are many types of LEDs, which include low, medium and high brightness. The amount of LEDs being used and style or brightness level of LEDs will determine how many lumens a lamp or fixture emits. With LED technology, it is very important to manage heat that is generated out the back of the LED. The heat management is accomplished with either a heat sink or by the fixture housing. The cooler an LED operates, the longer the effective life will be.

Who can use LEDs?
LED light bulbs offer direct screw-in replacements for incandescent, halogen and compact fluorescent lamps. They are offered in a variety of color temperatures (CCT) to match your existing light temperatures. Therefore, anyone interested in saving energy and reducing cost can use LEDs.

LED Lighting Characteristics
LEDs emit directional light approximately from 120° to 140°. Secondary optics or lenses are used to direct the light into different patterns (narrow, flood, etc.). LEDs are offered in warm, neutral and cool white to match the color temperatures of conventional lighting.

Why would you use LEDs?
LEDs can be used anywhere standard incandescent or halogen lamps are used. You would use LEDs because of the energy efficiency and long life characteristics. LEDs can last up to 20 years and save you money in energy consumption, re-lamp frequencies and maintenance costs.

Why do we coat LEDs? 
Shat-R-Shield safety coats LEDs to protect against moisture, contaminants and harsh environments, which can cause corrosion and lead to premature failure. LEDs can last up to 20 years but can fail due to corrosion from contaminants. Shat-R-Shield’s coating seals the LEDs and provides the protection necessary for the lamps to last the rated life. If an LED’s lens or cover were to be accidentally broken, the LED most likely will still operate. Shat-R-Shield shatter-resistant coating will help prevent contact to the electrical connections of the lamp.
