Abstract

The invention provides a lighting device which comprises a light source, a light guiding plate, a shaft rod and rollable reflector plates. The light guiding plate is positioned at one side of the light source and has a first surface, a second surface relative to the first surface, a first side and a second side opposite to the first side. The shaft rod is positioned at the first side of the light guiding plate. The rollable reflector plates have fixed ends and movable ends, and the fixed ends are fixed on the shaft rod. The lighting device has a first state and a second state. In the first state, the fixed ends of the rollable reflector plates are fixed on the shaft rod, the movable ends are adjacent to the first side of the light guiding plate, and the rest of the rollable reflector plates are rolled on the shaft rod. In the second state, the rollable reflector plates are unfolded on the second surface of the light guiding plate, and the movable ends are adjacent to the second side of the light guiding plate.

Description

technical field [0001] The present invention relates to an illuminating device, in particular to an illuminating device having a flexible reflective sheet and having both single-side light emission and double-side light emission. Background technique [0002] In addition to being used as a backlight for a liquid crystal display panel, the current general side-type light source module can also be used for lighting purposes such as reading auxiliary lights or planar lamps. Take the reading auxiliary light as an example, because both sides of the light guide plate emit light, so as to meet the requirement of perspective. If it is used as a flat lamp, a reflector is usually added under the light guide plate to increase the brightness of single-sided light. The light source modules mentioned above have the form of single-sided light emitting or double-sided light emitting, but they cannot be used in common with each other due to different required characteristics. Relatively sp...
