Light regulation device and lighting device

A lighting device, comprising a collimating light source and a light regulation device, the light regulation device comprising:

• a first substrate, a first electrode layer being provided on the first substrate;
• a second substrate, a second electrode layer being provided on the second substrate;
• a surface of the first substrate on which the first electrode layer is provided being disposed opposite to a surface of the second substrate on which the second electrode layer is provided;
• and
• liquid crystals interposed between the first substrate and the second substrate;
• the first electrode layer comprises a plurality of electrode units, each of the electrode units comprising a plurality of electrode strips, each of the electrode strips being configured to be loaded a different driving voltage signal, and wherein the second electrode layer is configured to be loaded a common voltage signal;
• the first electrode layer comprises an upper electrode layer and a lower electrode layer, and an insulating layer is disposed between the upper electrode layer and the lower electrode layer;
• the upper electrode layer comprises a plurality of first electrode strips and the lower electrode layer comprises a plurality of second electrode strips;
• a projection of one of the second electrode strips on the first substrate is located between projections of every two adjacent ones of the first electrode strips on the first substrate, edges of adjacent first electrode strips are flush with edges of the second electrode strip;
• and
• each of the electrode units comprises at least one of the first electrode strips and at least one of the second electrode strips that are continuously distributed;
• and
• an exiting direction of light passing through liquid crystals at a position corresponding to each of the electrode units is deflected in the same direction,
• wherein the light regulation device is disposed in a light-exiting direction of the collimating light source.
