The invention belongs to the technical field of optical physiotherapy equipment, and provides a physiotherapy lamp comprising an casing having an opening at one end, and a group including a light source plate, a reflection cup and a lens which are successively disposed in the casing, wherein a plurality of quasi-natural light LED light sources are disposed on the light source plate and each emitsquasi-natural light; the relative spectral power of the red light in the quasi-natural light is greater than 0.60; the relative spectral power of the cyan light is greater than 0.30; the relative spectral power of the blue light is less than 0.75; and the relative spectral power of the 640-700 nm red light is greater than 0.50. The physiotherapy lamp provides the quasi-natural light by the plurality of quasi-natural light LED light sources, has complete illumination spectrum and high color rendering illumination on the basis of ensuring the relative spectral power of the 640-700 nm red light for treatment, physiotherapy and health care, and improves an ability to distinguish colors. The low-blue-light illumination can reduce eye fatigue and dryness, and reduces a risk of color weakness. The physiotherapy lamp does not affect the vision of a user in use, can be used as a lighting fixture to enhance user experience and functional diversification.
