Light emitting diodes (LEDs) have come a long way in terms of illumination and energy efficiency over the past few decades. As a result, the popularity of LEDs in the field of lighting technology has skyrocketed, and recently, the emergence of white LEDs has drawn plenty of attention. As part of this white-LED revolution, VTEW1151ASE-57Y-TR has become a go-to option for lighting applications.

Description

VTEW1151ASE-57Y-TR is a high-power white LED, with a current of 190 mA at 3.3V. It is packaged in a surface mount package, specifically in a ChipLED package with transparent encapsulation, making it suitable for mounting onto circuit boards. The LED is built with a 0.5W power rating, and is available in several different beam angle and color temperatures.

Application Field

White LED lighting is suitable for a variety of applications. It has become especially popular for outdoor lighting, due to its energy efficiency, as well as its ability to light up a large area with very little brightness attenuation. VTEW1151ASE-57Y-TR is especially suitable for outdoor parking lot lighting, floodlights, and security cameras. It can also be used for indoor lighting for homes and businesses, such as staircases, hallways, and other hallways that need to be illuminated. Additionally, it has found applications in LED industy lightings.

Working Principle

The working principle of LED is based on the PN junction and electron recombination process. The LED is built with a semiconductor material doped with impurities, which creates an asymmetric barrier that allows electrons to flow in the forward direction. When the electron flow hits the PN junction, the electrons recombine with the holes of the P-type material, releasing energy in the form of photons. This photon release is the "light" emitted by the LED. In the case of VTEW1151ASE-57Y-TR, the specific wavelength of the light emitted is determined by a combination of the color temperature of the packaging material and the phosphor used in the chip.

Conclusion

VTEW1151ASE-57Y-TR is a high-power white LED with a 0.5W power rating, designed for use in both indoor and outdoor lighting applications. Its ability to provide a bright illumination over a large area with low brightness attenuation makes it a great choice for outdoor lighting and security applications, as well as LED industry lighting. Its working principle is based on electron recombination, with the wavelength of the light emitted being determined by the color temperature of the packaging material and the phosphor used in the chip.
