Abstract: A mobile vehicle, a ground treating equipment and an orientation adjusting method thereof are provided. The ground treating equipment includes a frame, a ground treating unit, a connecting rod set, a connecting rod driving unit, a rotation driving unit, two pressure sensors and a controller. The ground treating unit is mounted at the frame. Two ends of the connecting rod set are connected to the frame and the mobile vehicle. The connecting rod driving unit is mounted at the connecting rod set for adjusting the orientation of the connecting rod set. The rotation driving unit is mounted between the frame and the connecting rod set for driving the frame to rotate relative to the connecting rod set. The pressure sensors are mounted at the frame for sensing two pressure values between the frame and ground, or the pressure sensors are mounted at the rotation driving unit for sensing two pressure values while the frame is driven to rotate clockwise and counter-clockwise.

Abstract: An illuminating device includes a first light module and a second light module. The first light module emits a first light beam to a first illuminating area, and the second light module emits a second light beam to a second illuminating area. The first light module includes a first blue chip emitting a blue light with a main wave peak from 461 nm to 480 nm.

Abstract: The present invention provides an apparatus for controlling a three-dimensional optical field. The apparatus includes a light-emission device and a set of zoom elements. The light-emission device emits a light. The set of zoom elements are disposed in front of the light-emission device, and focus the light from the light-emission device.

Abstract: An optical lens and a lamp containing such optical lens suitable for use in commercial refrigerators are provided. The lamp has an overall long shape. The optical lens produces a bat-wing type of lighting distribution. The optical lens comprises a light incident surface and a light exit surface. The light incident surface comprises a sawtooth-like structure having a plurality of sawtooth-like protrusions. Each of the sawtooth-like protrusions respectively comprises a peak, and a respective valley exists between every two neighboring sawtooth-like protrusions. The distances between the light exit surface and the valleys between every respective two neighboring sawtooth-like protrusions are approximately the same. The sawtooth-like structure of the optical lens helps produce the bat-wing type of lighting distribution. The thickness is generally uniform throughout the optical lens.
