The present invention provides a light-emitting module, which comprises a light-emitting device, a light-guiding member, and an external light-guiding member. The light-emitting device emits light. The light-guiding member is disposed on the light-emitting path of the light-emitting module; the external light-guiding member is disposed on the light-emitting path of the light-emitting member. The light-guiding member distributes the light over the light-incidence surface of the external light-guiding member uniformly. After the external light-guiding member, the light is modified to axially symmetric light. Besides, the light-emitting device is disposed in a reflection ring, and a diffuser is disposed on the light-emitting path of the light-emitting device. When a minority of the light-emitting device fail, although the overall energy of the light source is reduced, the influence on the light emission of the light-emitting module is not significant. Thereby, the distribution of luminance will not differ significantly.
