Abstract
A projector includes a light source module, a light valve, and a projection lens. The light source module includes a substrate, at least one light emitting element, a heat conducting structure, and at least one electricity insulating and heat conducting element. The light emitting element is disposed on the substrate, and has a conductive portion. The light emitting element provides an illumination beam. The heat conducting structure has at least one concave. The substrate is disposed in the at least one concave, and the conductive portion is located in the concave. The electricity insulating and heat conducting element is disposed in the concave, and covers the substrate and the conductive portion. The light valve is disposed on a transmission path of the illumination beam, and converts the illumination beam to an image beam. The projection lens is disposed on a transmission path of the image beam.
