  • Patent number: 9488472
    Abstract: Provided are an apparatus and a method for measuring a three dimensional shape with improved accuracy. The apparatus includes a stage, at least one lighting unit, a plurality of image pickup units and a control unit. The stage supports an object to be measured. The lighting unit includes a light source and a grid, and radiates grid-patterned light to the object to be measured. The image pickup units capture, in different directions, grid images reflected from the object to be measured. The control unit calculates a three dimensional shape of the object from the grid images captured by the image pickup units. The present invention has advantages in capturing grid images through a main image pickup portion and sub-image pickup portions, enabling the measurement of the three dimensional shape of the object in a rapid and accurate manner.

  • Patent number: 9459396
    Abstract: An edge-lit lighting apparatus includes a light source and a light guide body. The light guide body includes an input edge, the light source positioned to project light through the input edge in a primary emission direction, the light guide extending from the input edge. The light guide body includes a mean elongation plane which is angularly offset from the primary emission direction. The light guide body includes a reflective side adjacent the input edge and configured to redirect light from the light source. The light guide includes an output side configured to disperse redirected light from the reflected side. The light guide body can extend curvilinearly from the input edge. The lighting apparatus can be configured as an indirect lighting system, and can help increase efficiency for edge-lit lighting systems.

  • Patent number: 9423652
    Abstract: A light source assembly includes a base plate, a light source secured on the base plate, a first reflection member, a second reflection member, and a diffusion plate. The first reflection member includes a base portion secured on the base plate and a plurality of protrusions with reflection surfaces inclined to the base plate. A through hole is defined on the base portion to receive the light source. Each protrusion protrudes from a side of the base portion away from the base plate and extends around the through hole. The second reflection member includes a reflection portion defining a plurality of light holes. The diffusion plate covers the second reflection member. Light emitting from the light source transmits to the light guide assembly via the reflection portion and the reflection surfaces.

  • Patent number: 9297514
    Abstract: A lighting system having a reflector with a plurality of reflecting surfaces. The plurality of reflecting surfaces have at least one optical axis, and the reflecting surfaces further include a linearly projected cross-section along a respective linear axis. A plurality of light emitting diodes (LEDs) are positioned in a line generally parallel to the linearly projected cross-section of the plurality of reflecting surfaces. The LEDs are oriented relative to an associated reflecting surface such that a central light-emitting axis of the plurality of LEDs is angled relative to the at least one optical axis of the associated reflecting surface at about 45°. The reflecting surfaces redirect and collimate a light output of the plurality of LEDs at an angle of about 45° with respect to the central light emitting axis of the plurality of LEDs.

  • Patent number: 9140414
    Abstract: A landscape lighting system includes a light fixture having an LED and an LED driver for controlling operation of the LED. The system includes a plurality of interchangeable light diverting elements adapted to be secured over the LED, whereby each light diverting element has a unique light diversion angle associated therewith, and whereby only one of the light diverting elements is secured over the LED at any one time. The system includes a light intensity controller in communication with the light fixture. The light intensity controller includes a control element that enables an operator to selectively increase and decrease the intensity of the light generated by the LED. The light intensity controller includes indicia provided thereon that indicate the intensity level of the light generated by the LED. The light intensity controller is used for finely tuning the intensity of the light generated by the LED.

  • Patent number: 9121599
    Abstract: A structure of an outdoor illuminating device has a lamp housing disposed on a substrate. The light-emitting element of a light source module is disposed under the substrate. The heat sink of the light source module is interposed between the substrate and the lamp housing. A transparent mask covers the substrate from below, and is fixed to the substrate by a fastening element, thereby forming a closed chamber that prevents moisture from entering. The light-emitting element is inside the chamber, and the heat sink is outside the chamber.
