ELM 4-920

ELM 4-920 is a type of LED, spacers, and standoffs. It is a very reliable and efficient type of light source with many advantages. It has a bright output, a long life span, and extremely low power consumption. The ELM 4-920 is also suitable for a variety of applications including backlighting, accent lighting, and illumination, and its small size makes it ideal for use in tight spaces.

The ELM 4-920 consists of a white LED on an aluminum oxide substrate. The substrate is covered by an outer epoxy shell, which acts as a protective layer that shields the LED from the environment. The LED and substrate are suspended in a polycarbonate mounting that provides mechanical support and electrical contacts. The polycarbonate mount also acts as a heat sink, helping to dissipate the heat generated by the LED.

The ELM 4-920\'s working principle is based on the effect of a P-N junction. A P-N junction is created when two semiconductors—one P-type and one N-type—are positioned adjacent to one another. When the N-type semiconductor and the P-type semiconductor are contact, electrons are able to move from the N-side to the P-side creating an electric current.

The LED is an N-type semiconductor, and the substrate is a P-type semiconductor. When the LED is mounted on the substrate, it creates a P-N junction. When a voltage is applied across the junction, electrons are able to flow from the N-side to the P-side and creates a current of electricity. This current creates a field of light caused by the electrons flowing through the junction.

The light generated by the ELM 4-920 can be directed wherever needed as it is adjustable in color and intensity thanks to the semi-reflective cover that goes over the LED. This cover can be easily changed to create a different lighting effect. The LED also has great life expectancy, lasting up to 50,000 hours, providing energy efficiency and long term savings for commercial and residential applications.

In conclusion, the ELM 4-920 is an extremely reliable, efficient and adjustable LED, spacers, and standoffs that can provide many benefits. Its adjustable colors and wide range of applications make it an ideal choice for many homes and businesses. The bright output, long-life span, and low power consumption make it a great choice for commercial/residential customers looking to maximize their energy efficiency and long term savings.
