ELM31905BC-3

ELM31905BC-3 are light emitting diode (LED) devices used for circuit board indicators, arrays, light bars, and bar graphs. LEDs have been around for many years and are widely used for various applications such as automobile taillights, LCD TV clocks, digital watches and many more. LEDs are an energy efficient and reliable illumination source.The ELM31905BC-3 is a single-diode LED with a wide range of luminous flux. It is available in the following colors: red, green, yellow, orange, and blue. The power consumption is low, making it ideal for applications where energy efficiency is a priority. The device is IP67 certified, making it suitable for outdoor use.The ELM31905BC-3 offers a range of working principles. These include direct drive, AC drive, and pulse width modulation (PWM). In direct drive mode, the current is continuously applied to the LED and is proportional to the voltage. AC drive is an alternating current drive system, where the current and voltage are varied in an alternating fashion. The PWM drive system is used when current consumption or voltage fluctuation is undesirable. The ELM31905BC-3 is also equipped with an over-temperature protection feature, which prevents the LED from being damaged due to long-term operation at excessive temperatures.The ELM31905BC-3’s working principle is based on the principle of electroluminescence. Electroluminescence is the emission of light when an electrical voltage is applied to a semiconductor material. The device contains a dielectric material between two electrodes (an anode and a cathode) which is energized by an electrical current and emits light. The current flows through the diode and is conducted by the anode and cathode, which then produce light.The ELM31905BC-3 has a wide range of applications due to its flexibility. It can be used for indicators, displays, billboards, signs, backlighting, automotive lighting, emergency lighting, and architectural lighting. It is also ideal for display, communication, and decorative lighting applications. It is also used for high power LED applications such as street lamps and grow light fixtures. For the best results, the ELM31905BC-3 should be operated within the manufacturer-recommended specifications, such as maximum current and voltage, as specified in the datasheet. The device should be handled carefully, as excessive voltage and current can damage the LED.In conclusion, the ELM31905BC-3 is a light emitting diode device used for circuit board indicators, arrays, light bars, and bar graphs. It is available in red, green, yellow, orange, and blue and offers a range of working principles including direct drive, AC drive and PWM drive systems. The device is also IP67 certified and is suitable for outdoor use. It has a wide range of applications and should be operated within the designated specifications for optimal performance.
