More Information
Summary:Disclosed is an LED illumination device of a straightforward construction, in which thermal resistance can be suppressed to a low level and in which heat generated from the LED element can be efficiently radiated. Rigidity of a mounting plate (16A) is guaranteed by a high wall (1622), making it possible to withstand the saturated vapour pressure of the working fluid (28) for cooling that acts on the mounting plate (16A) and also the vacuum condition or reduced-pressure condition close to vacuum when the working fluid (28) for cooling is introduced, without deformation of the mounting plate (16A). Consequently, the rigidity of the mounting plate (16A) is secured by the wall (1622), so the wall (1620) constituting the bottom face (1610A) of the recess (1610) can be made thin, which is extremely advantageous for efficient cooling of the LED element (14), by efficient conduction of the heat generated from the LED element (14) to the working fluid (28) for cooling.
