Abstract: A lamp with functions of adjusting an illumination direction is disclosed. A substrate is disposed on a base and includes a through groove. At least one light source is disposed on the substrate. An electronic control unit is disposed in the base. A telescopic member is disposed in the base and is connected to the electronic control unit. The electronic control unit drives the telescopic member to elongate and shorten. A flexible light guiding sheet is connected to the telescopic member. When the electronic control unit drives the telescopic member to elongate, the flexible light guiding sheet protrudes onto the substrate via the through groove of the substrate and deflects toward a specific direction, changing the illumination direction of the light source.

Abstract: A light emitting diode chip structure includes a substrate, a mesa type light emitting diode structure, and an electroluminescent layer. The mesa type light emitting diode structure includes a first semiconductor layer, a light emitting layer, and a second semiconductor layer. The mesa type light emitting diode structure is formed on the substrate. The first semiconductor layer is formed on the substrate. The light emitting layer is formed on a portion of the first semiconductor layer, and a portion of the first semiconductor layer is uncovered. The second semiconductor layer is formed on the light emitting layer. The electroluminescent layer is formed on the second semiconductor layer. Furthermore, a light emitting diode element is also disclosed herein.

Abstract: A Light emitting diode (LED) includes a substrate, a LED chip, a wavelength conversion layer, a lens and a reflective layer. The LED chip is mounted on the substrate. The wavelength conversion layer covers the top surface of the LED chip and exposes the lateral surface of the LED chip. The lens is disposed on the substrate and encloses the LED chip and the wavelength conversion layer. The reflective layer is disposed on the lens for reflecting the light emitted from the lateral surface of the LED chip.
