Definitions

  • the present invention relates to a lighting fixture for improving the luminance of a lamp tube, especially to a lighting fixture that reflects light off an arc-shaped reflecting panel and a lampshade for enhancing light output efficiency and reducing glare.
  • Taiwan Utility Patent Nos. M326615 and M330418 both provide lighting fixtures with reflecting sheets, so as to improve luminance and enhance light output efficiency.
  • Taiwan Utility Patent No. M326615 discloses a device 1 for improving luminance of a fluorescent lamp, which includes a reflecting sheet 10, a housing 12 and two retaining clamps 20.
  • the reflecting sheet 10 is disposed under and protected by the housing 12.
  • a lamp tube (not shown in figure) is disposed below the reflecting sheet 10 and is clasped at two ends by the retaining clamps 20.
  • the concave surface of the reflecting sheet 10 can reflect the rays of light emitted from the lamp tube so that the luminance of the fluorescent lamp is thus enhanced.
  • the device 1 mentioned above has only one reflecting sheet 10 with concave surface, and it is incapable of fully reflecting the rays of light. Thus, the device 1 only increases limited luminance, and is unable to reduce glare.

  • the fourth side of the partition is opposite to the third side thereof.
  • the fifth surface and the sixth surface respectively are received and inserted in the inserting holes of the first side plate and the second side plate.
  • the seventh surface has reflectivity and has a second arc-shaped face, and is disposed at a fifth side of the partition and connected to the third surface, the fourth surface, the fifth surface and the sixth surface.
  • the seventh surface is facing towards the lamp tube.
