LED indication has a wide range of applications in several fields, ranging from lighting up the visible space to indicating status or warning level in a particular area.

HLMPK150C4R0 is an example of one of these LED indications and this article will focus on its field of application and working principle. The HLMPK150C4R0 is a two-color chip mounted on 8-pin DIP package and is used for discrete side-showing and through-hole mount. It features a red and a green high-intensity chip with a wide viewing angle, which provides good visibility in the dark, a uniform light distribution, low power consumption and fast turn-on time.

HLMPK150C4R0 is primarily used as an application field indicator, which can be used to display the status or warning level of a process. It is also used in miscellaneous displays, including alphanumeric character displays, LED matrices and LED signs. The LED chip is composed of two separate LED chips, one red and one green, which provide greater visibility and usability than the traditional single LED indicators. The LEDs are designed to operate in both the normal (static) and flashing (blinking) modes and are adjustable via a current-setting resistor.

The working principle of the HLMPK150C4R0 is fairly straightforward. The chip consists of two separate LED chips, which are wired in series to a common current source. The current source then supplies the same current to both LEDs, allowing the emitters to generate their own light. The LED chip is equipped with a special light concentrator, which intensifies and distributes the generated light evenly for a more dramatic and powerful effect.

In summary, HLMPK150C4R0 is a reliable and versatile LED indication device. It is a two-color chip with a wide viewing angle, low power consumption, fast turn-on time, and adjustable current setting. It is used in various application fields, such as a warning indicator, miscellaneous display, and alphanumeric character display and have a straightforward working principle.
