  • Patent number: 12218185
    Abstract: To provide a thin film capacitor in which warpage is less likely to occur. A thin film capacitor includes: a metal foil having roughened upper and lower surfaces; a dielectric film covering the upper surface of the metal foil and having an opening through which the metal foil is partly exposed; a dielectric film covering the lower surface of the metal foil and made of a dielectric material having a thermal expansion coefficient smaller than that of the metal foil; a first electrode layer contacting the metal foil through the opening; and a second electrode layer contacting the first dielectric film without contacting the metal foil. The lower surface of the metal foil is thus covered with the dielectric film having a small thermal expansion coefficient, thereby making it possible to prevent the occurrence of warpage.

  • Patent number: 10295152
    Abstract: A light emitting diode lamp is composed of a light emitting diode, a band-pass filter and a light angle adjuster. The filter has a light cutoff function to cut off a light ray with a specific wavelength. The light angle adjuster allows the light rays emitted from the diode to be incident on the filter at incident angles of less than or equal to a maximum incident angle up to which the filter is capable of exerting the light cutoff function. The light angle adjuster is a reflector. The diode is mounted to a bottom portion. The filter is mounted to an opening. On an imaginary cross section including the optical axis, an angle formed between the optical axis and a straight line is less than or equal to the maximum incident angle, the straight line connects the emission center and an edge of the opening.
