  • Patent number: 9845928
    Abstract: An in-grade light fixture is provided with a corrugated housing design. The corrugated housing design enhances structural integrity and the flow of air within the light fixture to facilitate cooling. The light fixture includes an annular door with slots aligned with the corrugations to facilitate the influx of cool air into the housing and the exhaust of hot air from the housing. The light fixture includes a hot-aiming system that allows a tilt optic to be rotated via magnetic force within the light fixture using an external instrument, such as magnetic wand. The beam direction can be rotated using this hot-aiming system without opening the light fixture.

  • Patent number: 9639117
    Abstract: An electronic device having an expansion interface includes a shell, a button, a circuit board, switch and a voltage adjusting unit. The shell defines a through hole. The button is movably received in the through hole. The button includes a first electroluminescent portion and a second electroluminescent portion. The switch is electrically connected to the circuit board and is activated by the button to control whether to load a same voltage to the first electroluminescent portion and a second electroluminescent portion to drive them to emit light of equal brightness. The voltage adjusting unit changes the voltage loaded to the second electroluminescent portion to drive the second electroluminescent portion to emit light having a different brightness from the light emitted from the first electroluminescent portion when an expansion device is connected to the expansion interface.
