Light emitting diodes (LEDs) are a ubiquitous form of light source utilized in today’s society, from basic indicators on everyday home appliances to vehicles and technology. LEDs offer a variety of benefits over traditional light sources, such as longer life and lower power requirements. However, to ensure optimum efficiency and performance, a variety of different components and circuits are necessary. The KB2855CGKD is a type of device specifically designed to be used in LED applications. This article will look at its application field and working principle.

KB2855CGKD falls under the category of LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar Graphs. This type of LED arrangement is ideal for applications that require the use of multiple LED light sources, such as signs, displays, indicator lights and the like. The KB2855CGKD consists of a specific integrated circuit (IC) that is designed to power and control up to four LED strings. Each LED string can contain up to 24 individual LEDs in parallel, providing a total of 96 LEDs in total. The device also contains an onboard voltage regulator that allows for operation at both 5V and 3V, and provides current regulation up to a maximum of 1.2A.

In terms of working principle, the KB2855CGKD is an LED driver IC that operates in a variety of “modes”. In “sequential mode”, the KB2855CGKD enables the user to create custom lighting patterns with multiple lights. This is done by configuring each LED string with a defined sequence of patterns or colours. For example, one LED string may contain alternating colours of red and green, whilst the next LED string may contain a pattern of constantly changing colours. The “non-sequential mode” of operation is used for applications where a steady output of light is required. In this mode, individual lights can be configured to remain on or off, or to fade in or out as desired.

The KB2855CGKD is used in many consumer and industrial applications, including automotive systems and LCD displays. For automotive use, the device is often used in combination with an external PWM controller to create custom lighting patterns, such as dynamic turning signals. In LCD displays, the KB2855CGKD can be used to adjust the brightness and colour saturation level of backlights in displays. It is also used in various digital signage and display projects, often in combination with other driver devices.

To conclude, the KB2855CGKD is a versatile device that is used in many different lighting applications. It falls under the category of LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar Graphs, and offers a number of benefits such as high efficiency and the ability to create custom sequences of light. The device can be used in combination with external PWM controllers, as well as other driver devices, in order to create a wide range of lighting effects.
