温室补光灯，也叫植物补光灯，是依照植物生长的自然规律，根据植物利用太阳光进行光合作用的原理，使用灯光代替太阳光来提供给温室植物生长发育所需光源的一种灯具。

光照与作物的生长有密切的关系。最大限度的捕捉光能，充分发挥植物光合作用的潜力，将直接关系到农业生产的效益。近年来由于市场需求的推动，普遍采用温室大棚生产反季节花卉、瓜果、蔬菜等，由于冬春两季日照时间短，作物生长缓慢，产量低，因此急需进行补光。

Light Growing System is a lamp that uses light instead of sunlight to provide the light source needed for greenhouse plant growth and development according to the natural law of plant growth and the principle of plants using sunlight for photosynthesis.

Light is closely related to the growth of crops. Maximizing the capture of light energy and giving full play to the potential of plant photosynthesis will directly affect the benefits of agricultural production. In recent years, driven by market demand, greenhouses have generally been used to produce off-sea-son flowers, fruits and vegetables. In the winter and spring, the sunshine time is short, the crops grow slowly,and the yield is low, so it is practical to supplement the light.
