The LED chips can comprise an active LED structure. A dielectric reflective layer is included adjacent to one of the oppositely doped layers. A metal reflective layer is on the dielectric reflective layer, wherein the dielectric and metal reflective layers extend beyond the edge of said active region. By extending the dielectric layer, the LED chips can emit with more efficiency by reflecting more LED light to emit in the desired direction. By extending the metal reflective layer beyond the edge of the active region, the metal reflective layer can serve as a current spreading layer and barrier, in addition to reflecting LED light to emit in the desired direction.

If (i) a relation between the magnitudes of the first detection voltage and the second detection voltage has reversed, or (ii) if the first detection voltage deviates from a normal voltage range, a judgment unit asserts an abnormality detection signal.

  • Patent number: 10186644
    Abstract: Described herein are LED chips incorporating self-aligned floating mirror layers that can be configured with contact vias. These mirror layers can be utilized to reduce dim areas seen around the contact vias due to underlying material layers without the need for the mirror layer to be designed at some tolerance distance from the electrical via. This increases mirror area, eliminating lower light reflection in the proximity of the via and producing higher light output with greater light emission uniformity. In some embodiments, the mirror layer is formed with a contact via. This allows for a self-aligning process and results in the mirror layer extending substantially from the edge of the via.

  • Patent number: 10180226
    Abstract: A high/low beam switching device generally includes a fixing plate, a solenoid device, a shielding member, and a coil spring. The fixing plate defines an opening which is divided into three zones including an upper space, a middle space, and a lower space. The solenoid device is horizontally disposed in a frame fixed on a shelf extending from the fixing plate. The shielding member, which can cover the middle space of the fixing plate, is pivotally connected to the fixing plate. The solenoid device when being energized can turn the shielding member to uncover the middle space, so that a high beam illumination pattern can be provided. When the solenoid device is de-energized, the shielding member can be turned back to the fixing plate to cover the middle space, so that a low beam illumination pattern can be provided. Also, the present invention provides a headlamp including the switching device.
