The creation is a lighting device for micro dentists, including a light source； and a snap member, which is sleeved outside the light source, and the snap member has a window for the light of the light source to be directed outward； thereby, the upper and lower teeth of the patient bite respectively Tightly occludes the seat, and the seat is just at the edge of the lips. If there is a grip, the grip is located at the corresponding cheek. At this time, the LED can directly illuminate the patient through the window of the occlusion. Irradiation in the oral cavity to illuminate the inside of the oral cavity； thereby, the patient can bite the occlusal member while the oral cavity medical treatment is performed, so that the oral cavity can be kept open without causing sore muscles on the face, and the medical treatment can be smoothly performed.本創作係一種微型牙醫診療之照明裝置，包括光源；以及咬合件，套設在光源外，且咬合件具有視窗，供光源的燈光朝外照射；藉此，患者的上、下排牙齒分別咬緊二咬合部，而座體恰位在嘴唇邊，若有握把部的話，則握把部則位在對應的臉頰處，此時，LED恰可透過咬合件的視窗而將光線朝患者的口腔內進行照射，以照明口腔內部；藉此，患者在被進行口腔內醫療時，可以咬住咬合件而使口腔維持開啟而不會使臉部肌肉痠痛，更進一步能令醫療順利進行。
