Abstract: A wind power electricity generation system includes a wind shade, a rack, a rotary means and a wind directing means. The rack is fixedly located in the wind shade. The rotary means is mounted on the rack and can rotate thereon. The wind directing means is fixedly mounted on the rack and located at the front end of the rotary means to channel wind direction and accelerate the wind and direct the wind to blow at an optimal angle to the rotary means. Therefore, a greater amount of wind power is generated to drive the rotary means and the starting wind power of the rotary means can be reduced. As a result, the rotary means can rotate in a small wind environment to function as an electric power generation source.

Abstract: An LED luminescent light bar hung under a ceiling to hold a light bar with an LED as a light source includes at least one reflective back board made of extruded aluminum, at least one light bar, a driving means, at least one transparent lamp shade, two side plates and two hanging elements. The light bar and the driving means are installed on the reflective back board. The driving means is connected to the light bar to generate light. The transparent lamp shade and the two side plates also are installed on the reflective back board to seal the light bar. The light bar is installed under the ceiling through two hanging elements. The reflective back board provides higher reflection and greater heat dissipation, thus allows the light energy of the LEDs to be fully utilized to enhance luminescence. Heat can be dispelled quickly to avoid overheated and burn down.

Abstract: The present invention discloses an LED lamp bar, which mounts a plurality of LEDs and comprises an extruded aluminum reflection back plate, at least one LED carrier plate, at least one driver, a transparent lamp cover, and two side plates. The LED carrier plate and driver are arranged on the extruded aluminum reflection back plate. The LED carrier plate mounts the LEDs. The driver is coupled to the LED carrier plate and drives the LEDs. The transparent lamp cover and two side plates are installed on the extruded aluminum reflection back plate to encase the LED carrier plate and driver. The extruded aluminum reflection back plate features high reflectivity and high thermal conductivity can promote light efficiency and dissipate heat fast, wherefore the present invention is exempted from burnout caused by high temperature.
