摘要： A semiconductor light emitting heterostructure device is disclosed. The device comprises an n-type GaAs substrate, a first n-type laeyr of AlGaAs adjacent to the substrate, a second p-type light emitting AlGaAs layer adjacent to the first layer, and a third p-type AlGaAs layer suitable for bonding to an aluminum contact. The device starts with an n-type substrate which is more readily available and has a p-side up configuration which is more suitable for bonding to an aluminum contact.

摘要： A luminaire including a housing with a service compartment that is accessible through an opening in the housing, a light source, electrical components disposed in the service compartment for powering and operating the light source, and a door rotatably connected to the housing for rotation between a closed position where the door covers the opening and an open position where the door does not cover the opening. The rotatable connection includes an asymmetric pin extending from the door and a cavity formed in the housing having a hinge opening of width W. The asymmetric pin has a cross sectional thickness t and a cross sectional height h. Width W is less than height h and greater than thickness t, such that the pin is removable through the hinge opening when the door is in a removal position where the pin thickness t is aligned to the hinge opening width W.
