Description

technical field [0001] The invention relates to an LED lighting fixture, which belongs to the lighting field. Background technique [0002] With the continuous development of semiconductor and electronic technology, especially under the shortage of global resources, energy-saving LED (light-emitting diode) has been widely used as the lighting device of fluorescent light source. Compared with traditional gas fluorescent fluorescent lamp, it has high luminous efficiency, Long life, low driving voltage, environmental protection, miniaturization of lamps and other advantages, therefore, LED fluorescent lamps have gradually replaced traditional gas fluorescent fluorescent lamps. However, most LED fluorescent lamps currently on the market have no space for placing the DC power supply box in the housing, or the space for placing the DC power supply box is too small, and the DC power supply box is easily squeezed, resulting in a short circuit of the DC power supply box.
