| Title: |
Lighting Device Producing Light with Adjustable Color and Color Temperature |
| Abstract: |
A lighting device includes a light source, at least one seal block, at
least one wavelength conversion material and a concentration adjusting
unit. The light source emits light of a first wavelength. The wavelength
conversion material is filled in the seal block. The concentration
adjusting unit is disposed on the seal block for controlling
concentration distribution of the wavelength conversion material in the
seal block. The light emitted by the light source is absorbed by the
wavelength conversion material and converted into light of second
wavelength different from the first wavelength.
