F21V29/777 - CPC Classification

Classification description:

Protecting lighting devices from thermal damage; Cooling or heating arrangements specially adapted for lighting devices or systems; Cooling arrangements characterised by passive heat-dissipating elements, e.g. heat-sinks with fins or blades with essentially identical diverging planar fins or blades, e.g. with fan-like or star-like cross-section the planes containing the fins or blades having directions perpendicular to the light emitting axis
