Title:
HEAT DISSIPATING DEVICE AND ILLUMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/132500
Kind Code:
A1
Abstract:
Disclosed is a heat dissipating device equipped with a transformer (721), a power board (71) upon which the transformer (721) is disposed, and a heat dissipating unit (2) that dissipates the heat from the transformer (721), wherein the transformer (721) is disposed on the edge of the power board (71), and a heat conductor (5) is inserted between the heat dissipating unit (2) and the transformer (721). Since the transformer (721) is disposed on the edge of the power board (71), the heat dissipating unit (2) and the transformer (721) can be brought close together by adequately disposing the power board (71) on the heat dissipating unit (2). Since the heat conductor (5) is inserted between the heat dissipating unit (2) and transformer (721) that are close together, heat from the transformer (721) can be efficiently transmitted to the heat dissipating unit (2), and the heat from the transformer (721) can be efficiently dissipated.
