construção de diodo emissor de luz (led), método para ajuste do valor de saída de temperatura de cor de uma construção de led, e, meio para ajuste de uma temperatura de cor resultante de uma construção de led

摘要

A light emitting diode (LED) construction is disclosed, which comprises at least one LED unit (1); at least a first kind of LED die (3) of a first material; at least a second kind of LED die (4) of a second material; and a sealing member (5), comprising a wavelength converting material (6), wherein said at least first kind of LED die (3) is electrically addressable separately from said at least second kind of LED die (4), said at least one LED unit (1) comprises LED dies (3, 4) of both kinds, and at least one continuous portion of said sealing member (5), comprising wavelength converting material (6), is positioned to receive light emitted from both kinds of LED dies (3, 4). The LED construction further comprises means (7) for adjustment of a colour temperature resulting from said LED construction.
