Q19P1BXXW24E devices, also known as panel indicators, pilot lights, are widely used in many applications. This indicator serves as a warning to check the status of an internal process or equipment, identifying specifics such as whether a power supply is on or off, whether a temperature has exceeded the limit, or whether a pump is running or not.

This particular indicator is a LED lamp that comprises of an incandescent lamp encapsulated in a small circular disk which is surface mounted onto a PCB. The solid-state LEDs are directly connected in series with a fixed current limiting resistor without the need of a rectifying bridge or a regulated power supply. Its operation is as simple as a switch, having a single wire connection.

The LED indicator has wide application field in various industries such as medical and laboratory instrumentation, panel boards, automation/process control systems, consumer appliance, telecommunications, alarm systems, motor vehicles, and mobile equipment.

Specifically, this LED is used to identify the presence or absence of power supply, temperature condition, or alert status of equipment and processes. It is also used in applications or devices requiring a simple low-power lamp or indicator, such as signal lights, indicators, touch lamps, portable lighting, light rods, flash lamps, night lights, decorative finished lamps, alarm bells, and so on.

The operation of the LED indicator follows the standard principle of semiconductor PN junction diode. It only requires forward bias voltage to have forward current to flow for the LED to start emitting light. The color of the LED depends on the band gap energy of the LED chip. When the negative voltage is connected to the anode, the diode will not conduct, and no light will be emitted.

The power rating of the Q19P1BXXW24E LED is under 18W, yet the total dissipation is still relatively low as to not cause any damage to the LED. It also has a wide voltage input range of approximately 11 to 17V DC. Its switching voltage is as low as 2.2V and the current temperature range is around -20 to + 85 degrees, making it suitable for many low-voltage applications.

Due to its inherent properties such as low power consumption, minimized dissipation, and wide voltage input ranges, the Q19P1BXXW24E has become a preferred choice for many applications in a wide range of industries.
