Title:
熱的に変化する反射素子を備えた照明デバイス
Document Type and Number:
Japanese Patent JP2013504840
Kind Code:
A
Abstract:
The invention provides a lighting device (100) comprising a light source (10) arranged to generate light source light (11), an optional luminescent material and a thermally variable reflecting element (60). The optional luminescent material (205) is arranged downstream of the light source (10) and is arranged to convert at least part of the light source light (11) into luminescent material light (211). One or more of the light source (10) and the optional luminescent material (205) generate heat when the light source (10) generates light source light (11). The thermally variable reflecting element (60) is arranged downstream of the light source (10) and the optional luminescent material (205). The thermally variable reflecting element (60) has a first state wherein it is substantially reflecting and a second state wherein it is substantially transparent; heat induces a chance from the first state to the second state. The thermally variable reflecting element (60) is arranged to transmit at least part of one or more selected from the group consisting of the light source light (11) and optional luminescent material light (211) when being in the second state. The lighting device (100) is arranged to transport heat generated by one or more of the light source (10) and the optional luminescent material (205) to the thermally variable reflecting element (60).
