Abstract
The invention provides a lighting lamp which comprises a lamp shell, a main reflector, a light source and an auxiliary reflector. The main reflector and the light source are arranged in the lamp shell. The auxiliary reflector is connected with the lamp shell and arranged behind the light source. The main reflector is provided with a first heat dissipating hole, and the auxiliary reflector is provided with a second heat dissipating hole. According to the lighting lamp, due to the fact that the first heat dissipating hole is formed in the main reflector and the second heat dissipating hole is formed in the auxiliary reflector, cold air entering from the first heat dissipating hole in the main reflector is discharged through the second heat dissipating hole in the auxiliary reflector, circulation is formed, discharging of hot air in the lamp is accelerated, and the temperature of the lamp is effectively reduced. Thus, under the limitation of the appearance, the structure and the size of the lamp, the problems that the utilization rate of the light source of the lamp is low and the temperature of the lamp cannot meet the standard requirement are solved.
