Moreover, the present invention further relates to a lighting device having the lens of the type above.
Abstract:
The present invention relates to a lens having a first surface (1) and a second surface (2), wherein the first surface (1) and the second surface (2) are mirror symmetric to a first symmetric plane (A) passing through an optical axis (Y) of said lens and extend in a first direction (X) perpendicular to the optical axis (Y), wherein the curve profiles of the first surface (1) and the second surface (2) on the cross sections perpendicular to the first direction (X) are configured in such a way that light emitting from a light source (3) arranged at a predetermined position of a second surface side is refracted by the first surface (1) and the second surface (2) to be emitted in a direction which is offset from the optical axis (Y) by more than a predetermined angle. In addition, the present invention also relates to an illumination apparatus having the above type of lens.
Abstract:
The present invention relates to a lighting device, comprising: a lighting module (1); phosphor (12) disposed at a light output side of the lighting module (1); and an optical lens (2) provided at the downstream of the lighting module (1), wherein, a light mixing element (3) is further disposed between the lighting module (1) and the optical lens (2), wherein the light of the lighting module (1 ) and the light emitted by the phosphor (12) due to the excitation of the light of the lighting module (1) are emitted from a light mixing element exit surface (4) of the light mixing element (3) and enter the optical lens (2), wherein at least a part of the light is emitted after being reflected in the light mixing element (3). The lighting device according to the present invention does not generate or only generates unobvious color ring and can obtain uniform color distribution and controllable light density distribution as well as relatively small light loss.
Abstract:
