Radiator and plant illumination lamp

A plant illumination lamp, comprising:

• a lamp housing having a light source cavity, a light source mounted in the lamp housing and located in the light source cavity, and a radiator comprising (1) a heat-radiating baseplate configured for fixing a heat source, and (2) two heat-radiating side plates connected to the heat-radiating baseplate, two hooks each having two legs that are provided and are respectively connected to four mounting slots located on exterior side walls of the front and rear ends of the two heat-radiating side plates, wherein the two hooks are hang on a beam and there is a space left between the beam and the radiator or between the frame and the radiator to achieve a non-ceiling-mounted installation of the lamp;
• wherein each of the two heat-radiating side plates is provided with three pluralities of heat-exchanging through grooves running through the each of the two heat-radiating side plates, and the radiator is mounted at an upper end of the lamp housing, wherein each of two reflectors comprises a reflecting surface facing downwards;
• and the lamp comprises a lampshade, a light source, two end covers and the radiator, wherein the radiator is mounted at an upper end of the lamp housing;
• the light source is located in a light source cavity and mounted on a lower end surface of the heat-radiating baseplate;
• the lampshade is mounted on a lower end of the lamp housing;
• and
• the two end covers are mounted on the front and rear ends of the lamp housing;
• the light source cavity is formed by the lamp housing, the lampshade, and the two end covers;
• the heat-radiating baseplates, the heat radiating baseplate and the two reflectors are an integral structure from an aluminum sheet metal;
• the integral structure is provided with four threaded holes extending forward and backward so that the integral structure is connected to four corners of the two end covers via the four threaded holes;
• two threaded holes are located on two ends of the plurality of heat-radiating fins and two other threaded holds are located on outer ends of the two reflectors extending forward and backward;
• each of the two heat-radiating side plates is provided with three pluralities of heat-exchanging through grooves running through the each of the two heat-radiating side plates, and two air outlets are located on the exterior side walls of the each of the two heat-radiating side plates and are disposed in alternative ways with the three pluralities of heat-exchanging through grooves.
