The ELM14005YD, also referred to as a yellow-green LED, is a type of light-emitting diode (LED) used for indicating and signaling applications. It is a versatile, robust, reliable and economical LED light source that is used in a variety of ways, from lighting up signs and displays to simply though its presence creating set atmospheres. The ELM14005YD is categorized under LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar Graphs. As such, it is a very commonly used LED in these areas.

The ELM14005YD LED has a wattage of 4.6 watts and is specified with an average life expectancy of 50,000 hours minimum at a temperature of 80 oC. The forward voltage of the ELM14005YD LED is typically in the range of 9.5 - 10.5 V, while the typical forward current can range from 20mA to 50mA. The color temperature emitted by the ELM14005YD is somewhere in the range of 3200K - 8200K, depending on the specific model. The warm yellow-green color is long lasting, occupying a spectrum between yellow and green.

The application field of this LED makes it highly valuable for signaling or indicating purposes. It is typically used for lighting up displays in various industries, as well as for providing users with feedback where necessary. Additionally, ELM14005YD LEDs are commonly used for various sign and display interfaces, such as in retail store displays, industrial instrumentation and automation systems, and even military electronics.

In addition to its application field, the working principle of the ELM14005YD is based on the principles of the P-N junction, which is commonly used in semiconductor devices such as diodes, transistors and integrated circuits (ICs). The diode\'s junction acts as a two-way barrier that confines current flow and changes the voltage across it. When a voltage is applied, the diode allows current to flow in one direction but not the other. The electrons that are released by the P-N junction create a current of electrons that emits light when passing through the LED\'s material.

The key components of the ELM14005YD LED are the cathode and anode, each with their own distinct purpose. The anode connects to the positive voltage source, whereas the cathode connects to the negative voltage source. When a forward current is applied, the electrons released from the P-N junction create a current of electrons that immediately move from the anode towards the cathode, emitting light in the process.

Once the electrons have arrived at the cathode, the current of electrons continues to flow back up to the anode, creating a cycle of electron current as well as light. As long as current is applied, the LED will emit light and a tiny amount of heat. This process is what produces the light output in ELM14005YD LED, up to the specified wattage and color temperature described earlier.

In closing, we can see the value of the ELM14005YD LED in its ability to offer a versatile, reliable and economical light source. It is a highly popular and widely used LED, particularly in the areas of signaling, indicating and display applications. Its working principle is based on the P-N junction, which creates a current of electrons when a forward voltage is applied. As long as a voltage is applied, the ELM14005YD will continue to emit light and a small amount of heat.
