Abstract:
1. A lighting device, comprising: a light bar; two reflective covers, respectively connected to two opposite long sides of the light bar; and a reflective plate, positioned at a light output side of the light bar and spaced therefrom by a distance (H), wherein a reflective surface of the reflective plate faces the light output side of the light bar, and the reflective plate has a wavelength conversion layer positioned on the reflective surface thereof; the light bar emits a first wavelength light, and a portion of the first wavelength light is converted by the wavelength conversion layer of the reflective plate into a second wavelength light which is then reflected by the reflective plate to the two reflective covers, while the remaining portion of the first wavelength light not converted by the wavelength conversion layer is reflected by the reflective plate to the two reflective covers and mixed with the second wavelength light to give a light of a predetermined spectrum.
