This utility model relates to a lamp fixture, which includes an upper housing, a light-transmitting lampshade, and a lamp plate
assembly. The top of the light-transmitting lampshade is open, and the upper housing is detachably connected to the top opening of the light-transmitting lampshade. The lamp plate
assembly includes a support plate and a
light source disposed on the support plate. The
light source is detachably mounted on the support plate. Two opposite sides of the support plate are referred to as the first side and the second side, respectively. The first side is rotatably connected to the light-transmitting lampshade, and the axis of rotation extends along the length of the first side. The second side is detachably constrained to the light-transmitting lampshade. When the support plate is assembled on the light-transmitting lampshade and the light-transmitting lampshade is open relative to the upper housing, the
light source is located on the side of the support plate opposite to the opening of the light-transmitting lampshade. The light source is not exposed, which avoids contact with maintenance personnel and damage to the light source by external force, and also reduces the probability of the light source being damaged by
static electricity from the
human body.
