Kind Code:
B2
Abstract:
An illumination light source (100), comprising: one first light source (111), at least one second light source (112) and at least one third light source (113); a first fluorescent layer (131), excitation light emitted from the first light source (111) and excitation light emitted from the second light source (112) exciting the first fluorescent layer (131) from a back surface and a front surface, respectively; and a light guide element (140), the first light source (111), the second light source (112) and the third light source (113) being located at different sides of the light guide element (140), respectively, and both first fluorescent light emitted from the first fluorescent layer (131) and supplementary light emitted from the third light source (113) being emitted from a light emitting side of the light guide element (140); the first light source (111) and the second light source (112) simultaneously excite the first fluorescent layer (131), so that light emitted from the first fluorescent layer (131) has a high intensity; the first fluorescent light and the supplementary light are emitted from the light emitting side of the light guide element (140) after being guided by the light guide element (140), so as to form illumination light, so that the illumination light has a high brightness; in addition, the first light source (111), the second light source (112) and the third light source (113) are provided on different sides of the light guide element (140), respectively, providing a good effect of heat dissipation.
