In this embodiment, as shown in FIG. 14, negative ions 15 are generated from the support frame 9 that supports the first motor 10, and the negative ions generated at the same time as lighting can be used for air purification, dust removal, and antibacterial purposes. .. Negative ions can purify the air because the negative ions themselves have a negative charge and most of the dust and bacteria in the air have a positive charge, so the dust and bacteria neutralize with the negative ions and adhere. And fall to the ground. In addition, the negative ions 15 exert their own bactericidal effect to remove bacteria in the air, thereby maintaining the cleanliness of the air. Negative ions have health and care effects as one of the effective therapeutic means in natural remedies, and have obvious effects in the treatment and care of hypertension, insomnia, asthma, and cancer. Furthermore, negative ions can improve the state of sub-health, and have a remarkable effect on alleviation of symptoms such as dizziness and insomnia in pregnant women, improvement of immunity in children and development of brain function. The generated high-concentration negative ions help maintain health and remove static electricity in the environment that is harmful to the human body, creating a healthy, energy-saving and green space.
