Plant growth light and plant growing shed

A plant growing shed, comprising:

• a plant growth light, including:
• a housing enclosed to form a chamber with an opening at least at one end;
• at least two opposing ribs protruding from an inner wall of the housing towards the chamber, and a middle portion of each of the ribs is formed with a fastening groove;
• a heat dissipation member provided in the housing and opposite ends of the heat-dissipation member are snapped onto two fastening grooves, respectively, to divide the chamber into at least a heat dissipation channel and a lighting channel;
• a light board positioned close to the heat dissipation member in the lighting channel, and thermally connected to the heat dissipation member;
• and
• a fan provided close to the opening and forcing an airflow from the opening into the heat dissipation channel to accelerate;
• wherein at least a portion of the housing illuminated by the light board is translucent to enable light to pass through the translucent portion to plants to be supplemented with light located outside the housing;
• the housing is provided with a plurality of air outlet holes spaced in an extension direction of the heat dissipation channel to enable the accelerated airflow to be blown from the air outlet holes to plants to be ventilated located outside the housing;
• and
• wherein at least the fan is provided outside the plant growing shed to enable air from outside the plant growing shed to be accelerated by the fan and blown from the chamber through the air outlet holes to plants located inside the plant growing shed to be ventilated.
