Radiator and light module

The utility model provides a radiator which comprises a first cover plate and a vapor chamber, and a first cavity is formed in the first cover plate in a sunken mode. A plurality of heat dissipation areas are formed on the cavity surface of the first cavity; the vapor chamber is arranged in the first cavity and provided with a first surface and a second surface which are opposite, the second surface is attached to the multiple heat dissipation areas, and the first surface is used for making contact with a heating source. A plurality of heat dissipation areas are attached to the second surface of the vapor chamber, and the first surface is used for making contact with a heating source, so that the vapor chamber evenly transmits heat transmitted by the heating source to the first cover plate through the vapor chamber function of the vapor chamber, and the problem of temperature difference caused by contact difference between parts of a heated source and the vapor chamber is effectively solved; therefore, the pr
