  • Patent number: 9163808
    Abstract: A outdoor lighting fixture includes an enclosure, a heatsink, and an end-cap. The enclosure includes a cabinet and a cover that enclose control and power circuitry to provide power to illuminate a light source. The cabinet further includes an attachment face, and the extruded heatsink can be coupled to the attachment face. The extruded heatsink includes sides, a discontinuous plane of material formed with sides of the heatsink to provide a recessed mounting tray, and heat-conducting fins extending from the plane of material. The light source, which can include an LED light source, is coupled to the heatsink. The extruded heatsink can be coupled at one end to the attachment face of the cabinet at a position such that a space remains between the plane of material and a bottom edge of the attachment face, to permit water to drain from between the heat-conducting fins of the extruded heatsink.

  • Patent number: 7901118
    Abstract: A luminous pedal for a bicycle comprises a pedal, a luminous unit, and a rotary unit. The pedal has slots at two lateral sides respectively and a supporting portion in the middle. One end of the pedal is provided with an axial hole communicating with the supporting portion. The luminous unit has luminous portions and a coil seat. The luminous portions are disposed in the slots and the coil seat is detachably connected with a permanent magnet having a dentate part. The rotary unit includes an axial rod, a first gear, and a second gear. The first gear is disposed at the axial rod that is inserted into the axial hole. The second gear has a first disc and a second disc that are superimposed coaxially and the first disc is smaller than the second disc and the first gear. The two discs are engaged with the first gear and the permanent magnet. Thereby, the permanent magnet can be rotated rapidly by means of the differential ratio of the first and the second gears to produce enough electric power.
