This article tells how to classify the various LED lighting systems in the market, to make them more straightforward and acceptable. And we would make the method practical to cover most popular products such as LED bulbs, spotlights, par cans, fluorescent tubes, ceiling lights, floodlights etc. This classification is straightforward for most consumers to understand easily, and it’s also complied by many manufacturers unconsciously or intentionally. During our retail sales, we find out that most people would not try to dig into detailed performance characteristics of the LED lights, such as electrical, thermal or optical performance. Instead, they would prefer to know whether the item is compatible with their traditional lighting sources. In general, we would like to define LED systems into four categories. They are LED lamps, LED Fixtures, LED Portable and LED accessories.
- LED Lamps are those systems that can be mounted into standardized socket or sockets, among which the most popular are E26/E27, G5.3, GU10, T5 or T8. In traditional lighting sources, they include incandescent bulbs, MR16(or Multifaceted-Reflector halogen), PAR (or Parabolic aluminized reflector light), fluorescent tubes. They can be subdivided with their socket base for most cases. For example, there may be BULB-E27, MR16-E27, or PAR-E27 for bulbs, and for MR16, there may be MR16-G5.3, or MR16-GU10.
- LED Fixtures are those products that need to be installed with external wiring or plugins. They can be differentiated easily by checking whether they have an exerted wire. LED fixtures need to be mounted with extra fittings on pre-defined areas, such as opening on the ceiling or cabinet. LED ceiling lights, floodlights, wall lights, linear bars, flexible strips fall into this category. In addition, typical LED street lights and tunnel lights belongs to the fixture category, too.
- LED Portable are those finished portable products independent of external power. These products can be held in your hand or worn on your head. LED flashlights, headlights or keychains are among this category.
- The last part is not direct for lighting but essential for LED systems. LED Accessories include these items to support the stable operation. For many cases, power adapter is an important factor to guarantee lifespan and performance of LEDs. Dimmer control unit makes dimmability possible in LED lighting. There may be other special designed independent components to facilitate the product in heat sinking or beam distribution.
