Abstract: A lighting apparatus includes a light emitting diode, in which the light emitting diode includes an n-type nitride semiconductor layer, an active layer located on the n-type nitride semiconductor layer, and a p-type nitride semiconductor layer located on the active layer. The light emitting diode emits light that varies from yellow light to white light depending on a driving current.

Abstract: A filtering panel includes a molding layer part; a pattern layer part having an incident surface through which light emitted from a light source and viewing light transmitted to an observer enter, and an accommodation surface which is the reverse surface of the incident surface, wherein the molding layer part is stacked on the incident surface so as to be adjacent thereto, and the pattern layer part adjusts the optical paths of the emitted light and the viewing light; and a filtering layer part formed on a lower incident surface of the pattern layer part having the incident surface of the viewing light that enters from a lower region below a horizontal reference line, wherein the reflectivity of the visible light in the viewing light incident on the lower region is made greater than that of an upper region above the reference line by means of mirror reflection.

Abstract: The present invention relates to a method and apparatus for fault diagnosis of a programmable robot, and includes the steps of collecting sensing data corresponding to an operation of a programmable robot, identifying a program and motion related to the sensing data, generating an execution pattern based on the sensing data, extracting a standard pattern corresponding to the identified program and motion, and diagnosing a fault of the programmable robot by comparing the standard pattern with the execution pattern, and the present invention may be applicable as another embodiment.

Abstract: A light source device using a polarity of a material may include a transparent frame forming an inner space accommodating a nonpolarity material and a polarity material; a light source portion irradiating light through the nonpolarity material or the polar material accommodated in the transparent frame; and an electromagnet configured to switch respective positions of the nonpolarity material and the polar material by a magnetic force generated as a current is applied from outside of the light source device.
