Lighting device

A lighting device, comprising:

• a housing having at least one light entering plane, at least one light emitting plane and at least one guiding surface configured therein;
• a plurality of guiding blocks configured on the light guiding surface of the housing;
• at least one light source positioned adjacent to the light entering plane;
• at least one reflector covering at least a portion of the guiding surface of the housing;
• and
• wherein the light entering plane is located near a distal end of the housing such that the light that enters from the distal end of the housing to the guiding surface is further directed to the light emitting plane via the guiding surface;
• the reflector includes a reflection surface to reflect the light from the light entering plane to the light emitting plane;
• and wherein the reflector and the plurality of guiding blocks work together to direct the lights from the light entering plane to the light emitting plane by ways of reflection and/or deflection such that a substantially uniform lighting in an illuminated area opposite to the light emitting plane is obtained as each unit square of the illuminated area receives substantially the same amount of light.
