LEDs, particularly the various types of circuit board indicators, arrays, light bars, and bar graphs, are incredibly versatile and luminous forms of lighting sources. They often come in a variety of sizes, shapes, and colors and are used for a number of applications, such as automotive lighting, billboard illumination, LED display boards, and many more applications. One of the more popular LEDs used in several applications is the ELM14905RD or ELM14905RD series. This article will discuss the ELM14905RD application field and working principle in detail.

Application Field: ELM14905RD products provide users with a wide range of options for their specific needs. They are available in individually packaged products and are suitable for various types of power conversion applications, signal processing, medical devices, home appliances, control circuits, automotive electronics, and more. The ELM14905RD products are offered in bar shaped or doughnut shaped packages, with different pin configurations to choose from. Furthermore, they are available in the following sizes: small, medium, and large diameter. Depending on the application, the ELM14905RD products are certified with either the CE, RoHS, or UL regulations.

Working Principle: The working principle of ELM14905RD products is fairly simple. They utilize high frequency oscillation circuits, which enable the LED to rapidly pulse in order to create the illuminance. The LED is driven by a series of small transistors, which control the amount of current flowing through the LED. These transistors are connected in such a way that the total current is constant, regardless of the voltage applied to the LED. This ensures that the LED remains lit at a constant brightness, even if the voltage level varies. Furthermore, the heat generated by the LED is effectively dissipated through the use of heat sink technology, ensuring that the LED remains cool and efficient.

Moreover, it is important to note that the ELM14905RD products also feature a built-in internally compensated dimming control. This allows for controlled brightness levels, which are determined by setting a particular value on the control pins. The dimming control also helps preserve the life of the LED, while at the same time reducing power consumption and heat output. Furthermore, these products have a wide voltage range, typically anything between 3 and 24 volts. This makes them suitable for a wide range of applications.

In conclusion, the ELM14905RD products are highly versatile and luminous LED components, suitable for a wide range of applications. They feature high frequency oscillation circuits, dimming control, as well as a wide voltage input range. Furthermore, they are certified with CE, RoHS, or UL and come in small, medium, or large sizes. Overall, the ELM14905RD products are a great choice for any application requiring bright and luminous LEDs.
