Lighting apparatus

A lighting apparatus comprising:

• a power supply housing section which is composed of a cylindrical sleeve and which houses a battery cell or a contact portion, a shape of the contact portion being substantially similar to a shape of the battery cell, the contact portion being connected to an external AC adaptor;
• a circuit board housing section which extends from the power supply housing section and houses a circuit board, a part of a circumference surface of the sleeve being cut inwardly, a sectional area of the circuit board housing section being smaller than a sectional area of the power supply housing section;
• a light source housing section disposed at an end portion of the circuit board housing section;
• a cutout portion formed into the circuit board housing section in the power supply housing section, the cutout portion configured such that a part of a planar and inflexible record medium on which a hologram image or a holographic stereogram image was recorded or a part of a holder which holds the record medium is able to be inserted into or removed from the cutout portion, the cutout portion being formed at a predetermined angle corresponding to an incident angle of reference light with which a hologram was recorded;
• and
• a light source which is housed in the light source housing section and which emits light in a direction toward a portion of the record medium or holder that extends outwardly from the cutout portion,
• wherein an image recorded on the record medium is displayed in a state such that when the record medium is secured to the cutout portion an end portion of the power supply housing section and the portion of the record medium or holder that extends outwardly from the cutout portion are configured to support the lighting apparatus in a designated position when the lighting apparatus and record medium are placed on a surface.
