LED Indication - Discrete

LEDs have become increasingly popular for use in discrete applications, such as for indicator lights or for communication. As such, the VLMB31K2L2-GS18 is a popular choice for these types of applications. This LED is designed to provide a white light output with high brightness and visibility. The VLMB31K2L2-GS18 is a low power, low voltage led with a voltage of 2.7V to over 5.5V. This led has a wide viewing angle of 160 degrees and a flux of 160 lm. The input current is minimal at only 180 mA and the forward voltage is 3.2 V. The die size equates to a 3 mm x 3 mm package with a width of 1.2mm. It is constructed of aluminum and has a high temperature operating range of -30 to 90°C.The VLMB31K2L2-GS18 is typically used in backlighting applications that require energy efficient solutions. Specifically, many automotive interior lighting solutions or medical instruments have been built around the VLMB31K2L2-GS18. Its high flux output, combined with its low power consumption and small form factor, make it an ideal choice for a variety of LED applications.The VLMB31K2L2-GS18 works in a very straightforward way, by passing a current through the diode and creating electromagnetic radiation. The radiation emitted is then visible as light. This process of emitting visible light is often referred to as "electroluminescence". The light emitted from the diode is usually directional, or focused, due to the shape of the lens surrounding the diode.To increase the efficiency of the light output, the VLMB31K2L2-GS18 is designed with a phosphor coating to give it a more uniform light output. The phosphors absorb some of the light and then re-emit it at slightly different wavelengths. This coating helps to give the light emitted by the diode a more uniform appearance, rather than having an uneven or “patchy” light output.Overall, the VLMB31K2L2-GS18 offers a wide viewing angle, low power consumption and a uniform light output. This makes it a popular choice for many automotive, medical, and indicator light applications. The consistent output, reliability, and low power consumption make it an ideal choice for an increasing number of applications.
