Controlling LEDs - Conclusion

Note that just because a fixture and the desired control use the same control technology (ex: 0-10V) that does not mean they will perform well together. This is especially true with forward and reverse phase control, due to their lack of a formal standard. However, even control technologies that have a standard do not indicate anything about performance, they only pertain to compatibility...

Controlling LEDs Part 9 - Control types for LED products

Image via WikipediaThe following control technologies refer to the signal and wiring between the control on the wall and the fixture or lamp. LED retrofit lamps generally only use forward or reverse phase control technologies. LED fixtures may use any method, and it is independent of the driver type (constant current or constant voltage). The compatibility of a dimmer with a particular LED fixture begins with making sure they both...

Controlling LEDs Part 8 - What is the minimum or maximum number of LED fixtures/lamps that can be connected to one dimmer?

What is the minimum or maximum number of LED fixtures/lamps that can be connected to one dimmer? A common problem with LED system operation involves overloading the driver. LED drivers are rated for a maximum load (in volts, amps, and/or watts) that must not be exceeded. Similarly, some LED drivers may not perform well if too little load is put on them. The number of lamps able to be installed on a single phase control dimmer may...

Controlling LEDs Part 7 - What is the dimming performance of the product?

Each manufacturer defines dimming in a different way, but what you need to know is whether the dimming will be distracting or have noticeable, unexpected drops in light. The public’s experience with incandescent dimming is that it is smooth and continuous. Specifically, a change in the control (dimmer) position should be reflected by an equal change in light level. There should be no abrupt change in light level as the light source...

Controlling LEDs Part 6 - What is the dimming range of the product?

Incandescent lamps dim to below one percent perceived light, which looks like an orange filament glow. The dimming range of an LED lamp or fixture can vary greatly from one device to another. Some may dim to a minimum level of only 50 percent, while a different product may dim to one percent. Additionally, manufacturers will quote measured light numbers, but consumers are familiar with perceived light.  What is the difference? Measured...

Controlling LEDs Part 5 - What type of LED product am I using: an LED lamp or LED fixture?

LEDs are low-voltage devices. Therefore, additional electronic components are typically required to convert the line-voltage power to a low voltage for the LEDs. These electronics may also interpret control signals, and dim the LEDs accordingly. These devices are referred to as LED drivers. LED luminaires come in two distinct types: the LED bulb (also called an LEDi or retrofit lamp) and the LED fixture. LED bulbs have Edison-base...
