Abstract

The invention provides a multifunctional movable illuminating light which comprises a shell with a transparent window, a bottom cover and a switch, a parabolic reflector arranged in the shell and located at the inner side of the transparent window, an LED (light emitting diode) lamp arranged at the focus of the parabolic reflector and a battery arranged in the shell and located at the inner side of the bottom cover. The multifunctional movable illuminating light is characterized in that a controller is arranged in the shell, wherein the controller comprises an integrated circuit U1 which is connected with the illuminating LED, the integrate circuit U1 is connected with the battery through the switch, the battery is connected with a charging socket J1 through a protector FB, and the integrated circuit U1 is connected with an undervoltage prompt LED through a PNP triode. When being charged, the illuminating light can effectively prevent the battery from being exploded because of excessive charging current, prevent the battery from being subjected to short circuit or being burned because of excessive discharging current and prevent the battery from being damaged because of too high or too low voltage, thus effectively protecting the battery and simultaneously ensuring normal working voltages for the rest circuits. When the electric quantity of the battery is low, the illuminating light can give out an undervoltage prompt and meanwhile lighting can be entered into an emergency lighting state, therefore, multigear switching of the working state, namely full bright, half bright, flicker or close, can be realized. The multifunctional movable illuminating light has superior sealing performance and is safe and reliable.
