A LIGHTING DEVICE WHICH COLOUR AND COLOUR TEMPERATURE IS CHANGED

摘要

A lighting device includes a light source (1) emitting a ray with a first wavelength; at least a sealing block (2,3,4); at least one wavelength converting material (6,7,8) filled in the sealing block (2,3,4); and a mean for adjusting the consistency of the wavelength converting material (6,7,8) set on the sealing block (2,3,4) for control to control the consistency of the wavelength converting material (6,7,8) in the sealing block (2,3,4). When the ray crosses the sealing block (2,3,4), it can be converted to be the ray with a second wavelength by the absorb of the wavelength converting material(6,7,8).
