LED Indication lights are very popular due to their ability to provide on/off indication and discreet colors. The QLMT-PL98-STT11 is a high-power LED indication lamp specifically designed for industrial-level applications. It utilizes a very high-brightness LED and very low quiescent power in its operation.

The main application field of the QLMT-PL98-STT11 is in control systems, wireless communications, and consumer electronics due to its feature set. With its 120-degree viewing angle, a maximum luminous intensity of 2000 candelas, and a power usage of 6W, it is able to provide good visibility and brightness in most conditions. It is also able to work in temperatures from -40 to 85 degrees Celcius and is tolerant to a wide range of AC line voltages from 95 to 265VAC.

The power indicator of the QLMT-PL98-STT11 is able to indicate and respond to various states, providing both visual and auditory signal information. The power requirement and status of the indicator can be controlled with a signal (such as a TTL signal), or using a control signal via pulse width modulation (PWM). It can also be used for signal or relay control, or for safety and emergency stop requirements.

The working principle of the QLMT-PL98-STT11 is a combination of several technologies. It utilizes a high-efficiency direct drive circuit, a high-efficiency LED chip, and uses high precise circuit layout to provide a high brightness. The indicator also employs a multi-level voltage stabilization system, which ensures a stable and reliable output even under varying AC line voltages. Additionally, it has an integrated EMI filter and a multi-level surge protection circuit.

The LED light also incorporates a thermal protection system that monitors the junction temperature and shuts off the power when necessary. This helps prevent the indicator from exceeding its rated power requirements or running out of cooling range.

The above features, combined with its high reliability and excellent performance in harsh conditions have made the QLMT-PL98-STT11 a very attractive choice for those looking for a reliable LED indication light. It provides a great way to get the job done in difficult environments and still retain good visibility and brightness.
