Abstract
A traffic lamp includes a white light source, three color adjusting units, a panel, a light absorbing unit and a light diffusion unit. Each color adjusting unit includes a reflector and a color filter. The three color adjusting units are rotatable relative to the light source such that a part of white light emitted from the light source is filtered to be blue and then reflected to project on the panel by one color adjusting unit, and another part of white light is filtered to be green and yellow and then reflected to project on the light absorbing unit by the other two color adjusting units.
Claims19
A traffic lamp comprising:
- a white light source;
- a first color adjusting unit and a second color adjusting unit rotatable relative to the white light source, each of the first color adjusting unit and the second color adjusting unit comprising a reflector and a color filter mounted on the reflector, the color filter of the first color adjusting unit having a color different from that of the color filter of the second color adjusting unit;
- and
- a panel;
- wherein the first color adjusting unit is rotatable relative to the white light source between a first position where light emitted from the white light source is filtered to change color and reflected to project on the panel by the first color adjusting unit, and a second position where light emitted from the white light source is filtered to change color and reflected away from the panel by the first color adjusting unit;
- and
- wherein the second color adjusting unit is rotatable relative to the white light source between a first orientation where light emitted from the white light source is filtered to change color and reflected to project on the panel by the second color adjusting unit, and a second orientation where light emitted from the white light source is filtered to change color and reflected away from the panel by the second color adjusting unit.
A traffic lamp comprising:
- a white light source;
- a base;
- a first color adjusting unit and a second color adjusting unit pivotably mounted on the base;
- a light absorbing unit;
- and
- a panel;
- wherein when the first color adjusting unit is rotated to a first position where light emitted from the white light source is filtered to have a first color and reflected to project on the panel by the first color adjusting unit, the second color adjusting unit is rotated to another first position where light emitted from the white light source is filtered to have a second color and reflected to project on the light absorbing unit by the second color adjusting unit;
- wherein when the first color adjusting unit is rotated to a second position where light emitted from the white light source is filtered to have the first color and reflected to project on the light absorbing unit by the first color adjusting unit, the second color adjusting unit is rotated to another second position where light emitted from the white light source is filtered to have the second color and reflected to project on the panel by the second color adjusting unit;
- and
- wherein the first color is different from the second color.
