  • Patent number: 7960877
    Abstract: An electric reciprocating motion device includes a motor having a rotary shaft for outputting a reciprocating rotational power and a motion head coupling with the rotary shaft and being driven to move in a reciprocating motion along an axis of the rotary shaft and in a predetermined swing angle range. The motor is a spring motor including a motor unit and a torsion spring having two ends affixing at a motor housing and to the rotary shaft respectively. After the rotary shaft outputs a mechanical torque at one rotational direction, the torsion spring applies a spring force against the rotary shaft to drive the rotary shaft to rotate backward for generating the reciprocating rotational power. Using the spring motor in the electric reciprocating motion device, the device achieves the goals of simple mechanical structure, small volume, easy to install, and low in cost.

  • Patent number: 7946735
    Abstract: A LED light apparatus includes a conical reflection housing and a LED light source. The reflection housing has a vertex, a light opening aligning with the vertex, an inner flat reflection surface. The LED light source includes a light head alignedly pointing towards the vertex, wherein when the light head generates light a first portion of the light is accumulatively reflected by the reflection surface towards the light opening while a second portion of the light is projected towards the non-reflection arrangement to prevent the second portion of the light being reflected back to the light source for minimizing a black spot occurring at the light opening. Accordingly, the wide light pattern is refocused into a narrow beam pattern to improve the lighting efficiency. The distribution of the light output is regulated, and the heat generation is reduced.
