20140117857 | ILLUMINATION SYSTEM - An illumination system for a projection apparatus includes a light source module, an integrating rod and an optical detecting module. The light source module is capable of emitting an illuminating light beam. The integrating rod has a light entrance surface facing toward the light source module. The optical detecting module includes a light guiding device and an optical detecting device. The light guiding device has a first end surface and a second end surface. The first end surface is farther away from the light entrance surface of the integrating rod than the second end surface. The optical detecting device is disposed adjacent to the first end surface of the light guiding device and electrically connected to the light source module. The light source module is capable of adjusting intensity of the illuminating light beam according to randomly emitted light detected by the optical detecting device. | 05-01-2014 |

20130001910 | SWING SKATEBOARD - A swing skateboard includes a board body, a front roller unit and a rear roller unit. The front roller unit has a front roller fork rotatably disposed under a bottom face of the board body, and a front roller rotatably mounted on the front roller fork. The rear roller unit has a rear roller shaft mounted under the bottom face of the board body, and two rear rollers respectively rotatably disposed at two ends of the rear roller shaft. A user can wiggle his/her body to tilt the board body of the skateboard and laterally swing the front roller unit so as to control and move the skateboard forward. | 01-03-2013 |
20140210175 | SKATEBOARD WITH HIGHER OPERABILITY AND CONTROLLABILITY - A skateboard includes a board body, a front roller assembly and a rear roller assembly. The front and rear roller assemblies are mounted under a bottom face of the board body. The skateboard further includes an arch contact section. The arch contact section is a raised section disposed on a top face of the board body near the rear end thereof. When a user uses the skateboard, the arch of the user's rear foot is in snug contact with the arch contact section, whereby the foot is in good contact with the board body of the skateboard. The arch contact section also provides antislip effect for the user's foot. By means of the arch contact section, the user can more easily operate/control the skateboard. | 07-31-2014 |

20130170216 | ADJUSTABLE LED LENS AND LAMP WITH THE SAME - The adjustable LED lens has a body having a light incident surface and a light-emitting surface respectively mounted on two opposite sides of the body. The light-emitting surface has a concave tapered surface. The adjustable LED lens is mounted on a holder. A distance between the adjustable LED lens and the holder is changeable. An LED is mounted on the holder, wherein a light generated by the LED passes through the light incident surface and the light-emitting surface of the body. The concave tapered surface of the light-emitting surface increases a light distribution angle to increase an illumination range and decrease a glare. The distance between the adjustable LED lens and the LED is changeable to adjust a light shape as desired. | 07-04-2013 |
