An LED, or light-emitting diode, is a semiconductor device that emits visible light when an electric current passes through it. Normally the LED consists of several layers of semi conductor material, with the colour emitted from the LED dependant upon the material used.
What is COB?
Generally, this means Chip On Board which can be specifically related to an LED chip placed directly onto an electronic circuit board.
What is colour temperature?
Colour temperature refers to the warmth or coldness of the light produced by the lamp or LED,measured in Kelvin (K). Lamps producing a warm or yellow light have a low Kelvin (2700-3000K),while lamps producing a white or blue light have a higher Kelvin (3500-6500K). The ideal colour temperature is dependent on the application.
Generally with LED, the higher the Kelvin rating, the higher the lumen output. But most times the trade off is much poorer colour rendering (CRI) such as when items can appear very blue and therefore not their true colour appearance.
What is colour rendering or CRI?
Colour rendition describes the effect a light source or LED has on the appearance of coloured objects. The colour rendering capability of the LED is measured as the Colour Rendering Index,or CRI.
When comparing the CRI of different light sources such as LED's it is important to note that for the comparison to be meaningful, you should compare the LED's with the same colour temperature.
The higher the CRI , the better the ability of the light source to depict a true colour comparison.
How do you measure the brightness of a lamp?
There are a number of different measures to determine the brightness of a lamp, however the most common comparison will be the lumen output.
- Lumens refers to the light output of a lamp or LED in all directions (think of an imaginary sphere surrounding the light source and the light it is giving off in all directions)
- Candela refers to the light output of a lamp in a single direction (think of a spotlight)
- Lux is candelas, or light output in a given direction, measured at a specified distance (think of the amount of light you may want at your work desk, as opposed to the amount needed on the floor)
