Improved diode technology has resulted in this new category of LED, also referred to as a high-output LED as it offers a much higher lumen output than standard LEDs. These particular lights are slightly different from standard miniature LEDs in that they incorporate a suitable series resistor so as to directly connect to a higher-power supply. There are 5- and 12-V miniature LEDs available, too. There are three subtypes of miniature LEDs: low-current, standard, and ultra-high-output, all of which vary in terms of current, voltage, and total wattage, depending upon the manufacturer. As such, they are also used in sophisticated and technologically intense automated industries. Given their unique size and simple design, miniature LEDs can be placed directly onto a circuit board, with no need for a heat-controlling/cooling device. They’re used as indicators on devices such as cell phones, calculators, and remote controls. Miniature LEDs are considerably small, and usually available in a single shape/color. This is perhaps the most common form of LED available today. To help organize everything, LEDs are broken down into three main categories, and their subtypes appropriately consolidated: They’ve also led to more difficult decision making, as there are simply too many types of LED to choose from. These advancements have led to better illumination, longer service life, and lower power consumption. Today’s LEDs are available in many different types, shapes, and sizes, a direct result of the tremendous improvements we’ve seen in semiconductor technology over recent years. ![]() ![]() LED 101: Identifying different types of LEDs
