Abstract
A projection device and a light source module having a light transmitting region and a non-light transmitting region, and including a base, a light-emitting element, a collimating lens, an adhesive, and a light-shielding member are provided. The light-emitting element is disposed on the base at a position corresponding to the light transmitting region for providing a light beam. The collimating lens is disposed on the base. The adhesive is disposed on the base at a position corresponding to the non-light transmitting region, and located between the collimating lens and the base to bond the collimating lens and the base. The light-shielding member is disposed in the non-light transmitting region and covers a part of the collimating lens. A projection of the light-shielding member and a projection of the adhesive on the base at least partially overlap. The light source module and the projection device have good reliability.
