LED stands for "Light Emitting Diode," because they are small bulbs (known as diodes) that emit light when voltage runs through them. The voltage is applied to LEDs through electrical circuits, or circuit boards similar to those of computers. The parts that make up an LED are the LED bulbs themselves, a circuit board, optics (which guides the light emitted from the LED), a power supply, a fixture, and a lens.
Every LED bulb can emit three colors – red, green and blue. When lit up together, they are able to display a wide range of colors and imagery.
Pixel pitch is the distance between two LEDs horizontally and vertically, measured in millimeters.
The smaller the pitch, the higher the resolution is, and vice versa. The higher the resolution is, the more LEDs there are per row, and therefore, the clearer the image is.
Smaller pitches provide clear resolution from short viewing distances, (and therefore ideal for indoor displays) whereas larger pitches provide better resolution from further viewing distances (ideal for outdoor displays).
The main advantage of LED lighting is energy efficiency. With LEDs, up to 80% of electrical energy is converted to light energy - in comparison to other types of bulbs which operate at about 20% efficiency.
Another advantage is the lifespan of an LED - it is often significantly longer than most alternative lighting options, which also leads to significantly less maintenance and replacement fees.
Color temperature describes the warmth or coolness of a light.
The color of light is determined by the amount of heat that is applied. This color begins as red in appearance and can evolves into orange, yellow, white, and then blue-white at the highest temperature.
Red, orange, and yellow colors are considered warm, while blue-green colors are considered cool. HIGHER Kelvin temperatures (4000-6500 K) are considered cool while LOWER color temperatures (2700-3000K) are considered warm.
SMD stands for Surface Mounted Diode. This is an LED diode where the three colors are encapsulated and is fixed to the flat surface of the bulb. With this type of bulb, you will get a wider beam angle than traditional bulb types.
DIP stands for Dual In-Line Package. In a DIP display, the LED bulbs are separated from each other and are clearly visible. From every angle of the panel, the red LED, green LED and blue LED are visible. DIP offers a higher contrast compared to SMD, which remains flat on the surface.
LED lights are versatile and can be used in almost any application where incandescent or fluorescent lights are often used for indoor and outdoor use.
