  • Patent number: 11333314
    Abstract: Embodiments of the present invention relate to a lighting apparatus capable of providing three-dimensional effects at the same time as the surface emission of light sources by using a half-mirror member for reflecting and transmitting parts of light. In particular, by adopting the half-mirror member for transmitting a part of and reflecting another part of light emitted from a surface-emitting light source module, the present invention allows the implementation of a mirror-like image when the light is off, and allows the implementation of a light image providing various three-dimensional effects when the light is on.

  • Patent number: 10527250
    Abstract: Embodiments of the present invention relate to a lighting apparatus which allows a three dimensional effect to be felt while surface light is emitted in a light source using a half-mirror member configured to reflect and transmit some light. Particularly, the present invention employs a half-mirror member configured to transmit some light emitted from a light source module configured to emit surface light and reflect the remaining light to implement an image like that reflected by a mirror when the lighting apparatus is off and a light image through which various three-dimensional images are felt when the lighting apparatus is on.

  • Patent number: 5032205
    Abstract: A glow discharge etching apparatus includes a magnetic assembly for creating a surface magnetic field in close proximity to the walls of an etching chamber. An electrode is located within the chamber for supporting the object to the etched. A radio frequency signal is applied to the electrode so that it will emit secondary electrons upon bombardment by ions from an etching plasma created within the apparatus. A control plate may be positioned at various locations within the apparatus to regulate the amount of electron leakage to the control plate and thereby regulate the etching process. This apparatus provides improved uniformity and directionality of etching due to a low gas pressure and the surface magnetic field.
