A mirror assembly includes a first mirror and a second mirror. The first mirror passes a first color light therethrough, reflects a second color light and has an average transmittance (T1) of light with a wavelength of 380 nm to 420 nm. The second mirror reflects the first and second color lights from the first mirror, passes a third color light therethrough to mix with the first and second color lights, and has an average transmittance (T2) of light with a wavelength of 380 nm to 420 nm. The first to third color lights are combined at one side of the second mirror, while light having a wavelength of 380 nm to 420 nm travels on the other side of the second mirror.
