LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar Graphs- QLA694B2I

QLA694B2I is one type of LED indicator with several distinct advantages. It is one of the very few LED products that offer low power consumption of about 21 mW at 25mA. This LED is suitable for a range of applications, including backlighting of LCD, LED indicators, and LED signage.

The QLA694B2I LED offers a uniform light spread in an erathometric package. It also features a wide viewing angle of more than 110° and has a long lifetime. They are also designed to meet the demands of extreme environments, with a range of voltages, currents and colors available. The choice of colors is quite extensive, starting with red, yellow, blue and green, but also extending to amber, cyan, magenta and white.

Widely used in the industry, the QLA694B2I helps manufacturers to easily enhance their design with visible illumination and also provides a reliable source of lighting. The structure of the LEDs enables flexible installation, which enhances the decorative properties of OLEDs. This type of LED indicator is also an ideal alternative to the conventional incandescent lamps.

In terms of application field and working principle, the QLA694B2I LED has two major working modes. When the anode is connected to a positive Voltage, and the cathode is connected to a negative voltage, it will generate a forward current. This is referred to as the forward twinkle mode. In this mode, a base current is driven and the emitted light will flash on and off, in a periodic and orderly fashion.

On the other hand, when the anode and cathode are connected to a to the same voltage, either positive or horizontal, this is referred to as the reverse twinkle mode. In this mode, when the voltage is below a certain level, the LED will be powered off. There is also no light generated when the voltage is above a certain level. This is thanks to the two function modes and the pre-set voltage levels contained within the LED.

For LED illumination projects, the QLA694B2I LED can provide efficient energy consumption, better viewing angle and light output, and also be used for all types of decoration scenarios. Other benefits include a wide temperature range, high durability, good temperature uniformity and improved shock resistance. This type of LED is also extremely reliable and highly versatile.

Overall, the QLA694B2I LED is an ideal choice for retail, commercial, office and home lighting. It is also a popular choice for signage, displays, backlighting and strip lighting, making it an ideal choice for almost all illumination applications. The light output and color are easily adjustable, so that manufacturers can create their own unique lighting effects. Plus, thanks to its low power consumption, the QLA694B2I is extremely energy efficient.
