A light-emitting kite apparatus includes a kite and a light-emitting device attached to the kite. The light-emitting device includes a light source and a circuit for driving the light source. The light source is a luminescent panel. The light source is mounted on a first side of the kite and the circuit is mounted on a second side of the kite. Two wires are used to connect the light source with the circuit. The wires are extended through a hole defined in the kite. The light source is mounted on the first side of the kite via a hook-and-loop device. The circuit is implemented as a circuit board. A micro-controller is installed on the circuit board in order to drive the light source to emit light in various ways. A switch is installed on the circuit board so that the switch can be operated in order to select from the ways in which the luminescent panel emits light. A vibration detector is installed on the circuit board under control of the micro-controller for detecting and notifying the micro-controller of vibration so that the micro-controller can cause the luminescent panel to twinkle. A box is used to contain the circuit. The box is mounted on the second side of the kite via a hook-and-loop device.
