Abstract
A lighting device includes a light bar, two reflective covers and a reflective plate. The two reflective covers respectively connected to two opposite long sides of the light bar. The reflective plate is positioned at the light output side of the light bar. The reflective surface of the reflective plate faces the light output side of the light bar. 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 into a second wavelength light which is reflected by the reflective plate to the two reflective covers, while the remaining non-converted first wavelength light is reflected by the reflective plate to the two reflective covers and mixed with the second wavelength lights to give a light with a predetermined spectrum.
