TLDR4900

TLDR4900 is a sophisticated and reliable LED chip developed by telecommunications power engineering company to be used for discrete indication. It features more precise brightness adjustment than conventional resistor-based solutions. It also offers robust design, manufacturing and assembly. Discrete indication applications, such as status and fault indicators on electrical and electronic equipment, are rising in popularity as manufacturers increasingly need reliable and cheap solutions for lighting applications. The TLDR4900 LED chip has been specifically designed to meet this growing demand. It features an efficient, cost-effective and reliable indication design that is suitable for a wide range of applications. The most common application of TLDR4900 LED chips is in power and emergency lighting. The chip can be used as indicators on most types of emergency equipment, such as emergency exit lights, fire alarms, smoke detectors and fire extinguisher controls, helping to quickly alert occupants of a building in the event of an emergency. Additionally, the chip can be used in other electrical and electronic safety applications, such as fire sprinklers, heating and air conditioning systems, ventilation systems, and elevation systems.The working principle of the TLDR4900 LED chip is based on two separate circuit boards. The first board contains a discrete LED and current limiting resistors, while the second board contains power components and the chip controller, which activates and deactivates the discrete LED using an opto-coupler. In operation, the discrete LED is connected to the second board and the chip controller. When the LED is illuminated, the chip controller receives a signal via the opto-coupler and initiates the LED\'s on/off cycle. The LED then pulses, forming a recognizable light pattern, in order to provide an indication to operators. The TLDR4900 can be switched off when the emergency is over, using the same protocol.The TLDR4900 LED chip is an innovative and efficient device that provides reliable and accurate discrete indication for various applications. It reduces the need for external components and provides a high level of design flexibility, allowing manufacturers to quickly and easily install, test and customize the chip to meet their particular needs. Additionally, the chip is easy to assemble and requires minimal maintenance, making it an ideal choice for a range of discrete indication applications.
