HLMPQ155AZR LED Indication - Discrete

HLMPQ155AZR is a type of LED lamp that is used in indication applications. It is part of the discrete LED family, which refers to individual LED bulbs, rather than multiple LEDs that are bonded together. These discrete LEDs are commonly used when the application requires a single point of lighting, or in signs and symbols that are used to give information and instruction to viewers. The HLMPQ155AZR is produced by Avago Technologies and is produced in a number of different packages and colours. Primarily, the package type for these LEDs is the 3-terminal chip, also known as a "3-chip". The size of the package is 1206, meaning that it is 12mm long, and 6mm wide. The primary colours available in this particular model are yellow, green, red, and clear. As per the name, HLMPQ155AZR LED is primarily designed for indication purposes such as in light fixtures, displays, interior lighting, and similar projects that require a discrete LED. The HLMPQ155AZR LED is also very versatile, and can be used in a range of applications that require illumination, including outdoor signs and symbols, and automotive lighting. The working principle of HLMPQ155AZR LED is relatively straightforward. This LED operates through a process called electroluminescence, whereby an electric current is passed through the LED to create light. As the voltage and electric current vary, the LED produces different brightness levels. The LED consists of two layers of semiconductor material. The layer closest to the anode (or positive terminal) is N-doped, meaning that it has an excess of electrons. The other layer is P-doped and is connected to the anode. Unlike the N-doped layer, the P-doped layer has a shortage of electrons and is said to contain "holes". When a current passes through the LED, the electrons and holes combine at the junction to produce photons. These photons emerge from the LED in the form of visible light. The HLMPQ155AZR LEDs have a forward voltage of about 3V, meaning that in order for them to operate, a voltage of at least 3V is needed. In addition, the LEDs are designed with a built-in current regulatory system, allowing them to be used in applications that require higher voltage. The brightness of the HLMPQ155AZR LED is determined by the level of current that is supplied to the device. The amount of current supplied will directly dictate the amount of light that the LED produces. For example, a higher level of current will result in a brighter light, while a lower level of current will result in a dimmer light. The HLMPQ155AZR is a highly reliable and efficient LED, and is well suited to a range of applications. Some of the most common uses include static lighting, accent lighting, directional lighting, and signs and symbols. With its strong brightness and long life span, this LED is sure to meet the requirements of any lighting project.
