A sterilizing device.Including light equalizing device and luminous device,The light equalizing device has a light guide plate.The upper surface of the light guide plate is covered with a reflective layer.The interior is provided with a holding space.And the light guide plate is close to the inner surface of the holding space to form a light entering surface.The outer surface of the light guide plate which is not covered by the reflective layer forms a light surface.The light-emitting device is provided with a sterilized light source transmitter and a diffusion mirror in the accommodation space of the light guide plate.And the diffusion mirror is located on the upper side of the sterilization light source transmitter；When the light guide plate is placed on the substance to be sterilized,The sterilizing light source emitted by the sterilizing light source transmitter will refract and diffuse through the diffusion mirror.Enter the light guide plate from the light entering surface.After reflected by the reflective layer,The surface of the bactericide to be killed is radiated from the glossy surface for large-area sterilization.To improve the efficiency of sterilization.一種殺菌設備，包含有均光裝置及發光裝置，其中該均光裝置具有導光板，導光板上表面覆蓋有反光層，內部則設置有容置空間，且該導光板靠近容置空間之內側表面形成有入光面，而導光板未受反光層覆蓋之外側表面則形成有出光面；該發光裝置於導光板之容置空間內設置有殺菌光源發射器及擴散鏡，且擴散鏡係位於殺菌光源發射器上方側；當導光板置放於待殺菌物上時，該殺菌光源發射器所發出之殺菌光源會透過擴散鏡折射擴散，由入光面進入導光板內，經反光層反射後，由出光面射出至該待殺菌物表面進行大面積殺菌，達到提高殺菌效率之效果。
