    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.

  • Patent number: 9612387
    Abstract: A casing integrally includes a first accommodation part in which an optical part is accommodated and a second accommodation part in which an optical support is accommodated. Since the optical part which is a part of an optical plate member formed in a bent plate shape is supported by the optical support which is another part of the optical plate member, it is unnecessary to prepare a thick and robust member for supporting the optical part. That is, the first accommodation part side of a light source device can be made thinner. Moreover, the second accommodation part side of a display apparatus functions as a stand for stationary installation of the first accommodation part side of the light source device. It is therefore possible to reduce the size of the light source device and also the display apparatus, since it is not necessary to attach a separate stand to the first accommodation part side of the light source device.
