Eclairages LEDs
What are Edison LED lights?
Edison LEDs offer a vintage design with one or more strings of diodes that replicate the look of the filaments in a traditional bulb. They’ll often have an ST designation. Spot and flood light bulbs are two types of LED lighting that are good for specific uses.
What are LED light fixtures?
LEDs are incorporated into bulbs and fixtures for general lighting applications. Small in size, LEDs provide unique design opportunities. Some LED bulb solutions may physically resemble familiar light bulbs and better match the appearance of traditional light bulbs. Some LED light fixtures may have LEDs built in as a permanent light source.
What is a light emitting diode?
Light-emitting diodes (LEDs) are solid-state devices that convert electric energy directly into light of a single color. Because they employ “cold” light generation technology, in which most of the energy is delivered in the visible spectrum, LEDs don't waste energy in the form of non-light producing heat.
What are the different types of LED Christmas lights?
Holiday LED lighting can range from brightly colored LED string lights to interior and exterior holiday decorations: Many lighted indoor Christmas decorations also use LED lights. In addition to bulbs, you can find lighting fixtures with integrated LED lights.
What Exactly Is An LED?
An LED is a type of diode that turns electrical energy into light. For those that don’t know, a diode is an electrical component that only works in one direction. Basically, an LED is an electrical component that emits light when electricity flows through in one direction, from the Anode (positive side) to the Cathode (negative side). LED is an acr
Polarity Matters: Wiring LEDs
Electronic polarity indicates whether a circuit is symmetric or not. LEDs are diodes, therefore only allowing current to flow in one direction. When there is no current flow, there will be no light. Thankfully this means that if we wire an LED in backward, it will not burn the whole system up, it just won’t come on. The positive side of the LED is
Color Options
One of the great things about LEDs is the different options and kinds of light you can get from them. ledsupply.com
Led Brightness
LEDs are not only known for their colors, they are also a lot brighter than other light sources. Sometimes it is hard to tell how bright an LED will be because it is measured in Lumens. A Lumen is a scientific unit measuring luminous flux or the total amount of visible light from a source. Note that 5mm LEDs are usually listed in millicandelas (mcd
Viewing Angle and Optics
Our 5mm LEDs have listed viewing angles for each so just search for one that will work for you. As far as our surface mount LEDs go, most of them give off a very wide angle at 125 degrees Luckily, the LED starboards are compatible and easy to use with LED optics. These secondary optics are used to focus the light, they can reflect the light from a
How to Power LEDs
LEDs are known for having the best efficacy out of all other light sources. Efficacy is the measure of how well a light source produces visible light, also described as Lumens per Watt. In other words, how much light are we getting for our watt of power? To find this, first, find out the wattage of the LED in use. In order to find watts, you need t
How Much Voltage Do I Need to Light Up An LED?
This is a common question asked and is actually pretty easy to figure out. All you need to know is your LED(s) forward voltage. If you have multiple LEDs in series then you need to take into account all the forward voltages combined, if you have a parallel circuit then you only need to take into account the forward voltage of how many LEDs you have
Heat Control
Finding the wattage of your system also helps you know more about the heat control you will need. Since these LEDs are high-power, they do create heat which can be very bad as you can learn here. Too much heat will make the LEDs produce less light as well as cut down on the lifetime. We always recommend using a heatsinkand like to say to use about
Led Binning & Quality
With the LED industry growing at a pretty rapid pace right now, it is important to understand the difference in LEDs out there. This is a common question as LEDs can range from very cheap to very expensive. I’d be careful in buying cheap LEDs as you always get what you pay for, yes the LEDs might work great at first but they usually tend not to las
