How do I convert between candelas and lumens? You can’t directly convert since they measure different things. The most useful explanation I’ve found is that lumens measure light output at the source, while candelas measure the light that ... Are LEDs inherently directional? No. One way for a manufacturer to boost the luminous intensity spec (usually given in candelas or millicandelas) is to focus the beam more tightly. The same light flux, focused ... What is an LED driver? An LED driver is a self-contained power supply that has outputs matched to the electrical characteristics of your LED or array of LEDs. There are currently no industry standards, so ... Can LEDs be dimmed? It’s useful to think of an LED as a current-driven device. The light output is proportional to the drive current over a decent range. But things go a bit odd ... What is needed in a LED lighting system? To use some language borrowed from lighting designers, an LED lighting system would consist of an LED light source, ballast or driver, and a luminaire. The LED light source is ... How do you get more light out of an LED? LEDs are made by a process that deposits the junction materials on a substrate material. One of the limitations of LEDs is that imperfections in the material deposited on the ... |
