High efficiency heat dissipating device for lamps

Abstract

A high efficiency heat dissipating device for lamps is disclosed. The lamp comprises a light-emitting element, a heat conduction body and a lamp housing characterized in that the heat conduction body is mounted at the lamp housing and the light-emitting element is mounted at the heat conduction body, heat from the light-emitting element is transferred by contacting with the heat conduction body such that the housing provides a large area for the function of heat dissipation, and the interior and exterior of the housing are increased with a plurality of lamp hoods depending on the power of the light-emitting element, and the multi-layer lamp hoods are combined with lamps of different specification, the housing is adapted for solid illumination such that heat energy is dissipated via the surface area of the multi-layer lamp hoods and by means of convection current, a great amount of energy is dissipated and therefore the heat dissipation rate is increased.

1 . A lamp comprising a light-emitting element, a heat conduction body and a lamp housing characterized in that the heat conduction body is mounted at the lamp housing and the light-emitting element is mounted at the heat conduction body, heat from the light-emitting element is transferred by contacting with the heat conduction body such that the housing provides a large area for the function of heat dissipation, and the interior and exterior of the housing are increased with a plurality of lamp hoods depending on the power of the light-emitting element, and the multi-layer lamp hoods are combined with lamps of different specification, the housing is adapted for solid illumination such that heat energy is dissipated via the surface area of the multi-layer lamp hoods and by means of convection current, a great amount of energy is dissipated and therefore the heat dissipation rate is increased.
