Abstract

The present invention provides a lighting equipment, which successively includes a lamp head portion, a connecting portion and a tail portion; the lighting equipment further includes a short distance light source, a long distance light source, a power supply and a control switch. The short distance light source and the long distance light source are arranged inside the lamp head portion, and the light emitting direction of the short distance light source is consistent with that of the long distance light source. The power supply is provided inside the connecting portion, a positive electrode and a negative electrode of which are electrically connected to two ends of the short distance light source and two ends of the long distance light source respectively. The control switch is used for controlling a light and shade state of the short distance light source and the long distance light source.
