  • Patent number: 9795002
    Abstract: An illumination apparatus includes: a plurality of light emitting modules connected in series; a constant current source; and a fault detection circuit for detecting that the plurality of light emitting modules have at least one thereof with a short circuit fault. The light emitting module includes: an organic EL panel; a threshold value detection circuit configured to output a constant voltage when the organic EL panel between its anode and cathode has a potential difference equal to or larger than a threshold value; and a VI conversion circuit receiving the constant voltage from the threshold value detection circuit, converting the constant voltage into a constant current, and outputting the constant current. The fault detection circuit detects whether the plurality of light emitting modules have a short circuit fault based on a total value of the constant current output from each light emitting module.

  • Patent number: 9400094
    Abstract: A lighting apparatus may include a holding member, a lighting panel, and an attachment bracket for removably attaching the lighting panel to the holding member. The lighting panel may form a first position in which a light-emitting surface of the lighting panel and a light-emitting surface of a lighting panel are located substantially on the same plane with each other and a second position in which the lighting panel is pressed from its light-emitting surface side so that the attachment bracket pivots around a portion where the attachment bracket is attached to the holding member and the lighting panel is inclined with respect to the lighting panel. As the lighting panel forming the second position is moved in a direction away from the holding member the attachment bracket is released from the holding member, and the lighting panel forming the second position is readily removed from the holding member.
