ABSTRACT:
Lighting apparatus is provided comprising a light source (10), the light source being encapsulated in a protective medium (11) to seal the light source against ingress of moisture, the lighting apparatus having a heat sink (12, 13), the heat sink having a first region (12) in communication with light source (10) to receive heat from the light source (10) and a second region (13) which projects externally of the protective medium, such that the heat sink can dissipate heat to the ambient area. The invention provides light apparatus which is particularly suitable for use with caving lamps, although other uses are possible, for example in traffic lights or the lights of a motor vehicle, where the encapsulation would provide protection against rain.
