A In the middle of the LED SMD there is an N-type and a P-type semiconductor. The N-type has electrons and the P-type has holes. The holes and electrons rapidly cross the gap and then merge together. As they combine, it produces photons which in turn produces particles of light.
Q What is an LED strip light and how does it work?
A A LED strip light is a flexible circuit board that is populated with LEDs. Strip lighting allows you to install powerful, energy efficient, discreet lighting fixtures in places you normally wouldn’t be able to reach.
Q What are the main factors to look for before purchasing LED strip lights?
A
1. Make sure you know the requirements for your project, then when looking at options, compare lumen output, CCT, and CRI.
2. Compare LED strip size and number of chips on the reel.
3. Understand the wattage and voltage that the LED strip light uses.
4. Make sure that the products have verifiable quality.
Q What is IP stand for?
A This is a rating system that defines the ability of a product to be able to work in different environments. IP is an acronym "Ingress Protection". It is a measurement of the protection an item will have against solid objects (dust, sand, dirt, etc.) and liquids.
Q What is luminous efficacy?
A This is calculated by measuring the lumen output and then dividing that number by watts. For example, a strip that has a lumen output of 1200lm/meter and a wattage draw of 12w/m has an efficiency of 100lm/W.
Q What is Binning?
A Simply put, binning is the process of grouping LEDs during production so that they matched with LEDs of the same color sector. For example, all 2700K chips are ‘binned’ together and are separated from chips that have a higher/lower color temperature.
Q What is a Watt?
A A watt is equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential difference is one volt and the current one ampere. A watt is equal to the voltage multiplied by the amperage. This is how your electric company keeps track of how much energy you consume.
