    Abstract: A light emitting diode including a first-type semiconductor layer, an emitting layer, a second-type semiconductor layer, a first electrode, a second electrode, and a Bragg reflector structure. The emitting layer is configured to emit a light beam and is located between the first-type semiconductor layer and the second-type semiconductor layer. The light beam has a peak wavelength in a light emitting wavelength range. The first-type semiconductor layer, the emitting layer, and the second-type semiconductor layer are located on a same side of the Bragg reflector structure. A reflectance of the Bragg reflector structure is greater than or equal to 95% in a reflective wavelength range at least covering 0.8X nm to 1.8X nm, and X is the peak wavelength of the light emitting wavelength range.

    Abstract: Provided is a light emitting diode (LED) mounted on a carrier substrate and including a semiconductor epitaxial structure and at least one electrode pad structure. The semiconductor epitaxial structure is electrically connected to the carrier substrate. The electrode pad structure includes a eutectic layer, a blocking layer and an extension layer. The eutectic layer is adapted for eutectic bonding to the carrier substrate. The blocking layer is between the eutectic layer and the semiconductor epitaxial structure. The blocking layer blocks the diffusion of the material of the eutectic layer in the eutectic bonding process. The extension layer is between the eutectic layer and the semiconductor epitaxial structure. The extension layer reduces the stress on the LED produced by thermal expansion and contraction of the substrate during the eutectic bonding process, so as to prevent the electrode pad structure from cracking, and maintain the quality of the LED.

    Abstract: A light emitting unit includes multiple light emitting dice, a molding compound, a substrate and a patterned metal layer. Each of the light emitting dice includes a light emitting component, a first electrode and a second electrode. The molding compound encapsulates the light emitting dice and exposes a first surface of the first electrode and a second surface of the second electrode of each of the light emitting dice. The molding compound is located between the substrate and the light emitting dice. The patterned metal layer is disposed on the first surface of the first electrode and the second surface of the second electrode of each of the light emitting dice. The light emitting dice are electrically connected to each other in a series connection, a parallel connection or a series-parallel connection by the patterned metal layer.
