SEMICONDUCTOR LIGHT EMITTING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18213608 titled 'SEMICONDUCTOR LIGHT EMITTING DEVICE

Simplified Explanation

The patent application describes a semiconductor light emitting device that includes a light emitting structure, a transparent electrode layer, and a distributed Bragg reflector (DBR) layer.

  • The light emitting structure consists of a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer.
  • The transparent electrode layer is provided on the second conductivity-type semiconductor layer.
  • The DBR layer is provided on an insulating layer and consists of a first insulating film and a second insulating film with different refractive indices.
  • The insulating layer and the DBR layer have multiple holes connected to a contact region of the transparent electrode layer.

Potential applications of this technology:

  • Lighting: The semiconductor light emitting device can be used in various lighting applications, such as residential, commercial, and industrial lighting.
  • Displays: The device can be integrated into displays, including televisions, computer monitors, and mobile device screens.
  • Automotive lighting: The technology can be applied to automotive lighting systems, including headlights, taillights, and interior lighting.

Problems solved by this technology:

  • Improved light emission: The use of a distributed Bragg reflector (DBR) layer helps enhance the efficiency and directionality of light emission from the device.
  • Electrical contact optimization: The presence of multiple holes connected to the contact region of the transparent electrode layer allows for improved electrical contact and performance.

Benefits of this technology:

  • Higher efficiency: The device's structure and the DBR layer contribute to increased light emission efficiency, resulting in energy savings and improved performance.
  • Enhanced light directionality: The DBR layer helps control the direction of emitted light, leading to better light distribution and utilization.
  • Improved electrical contact: The design of the device ensures better electrical contact, reducing losses and improving overall device performance.
