A lighting device can include at least one LED light source having at least one LED chip, the LED light source being configured to impart a certain directivity to light emitted from the LED chip in a direction of the optical axis of the light source. A first reflector can be disposed in front of the LED light source and upwards with respect to the optical axis. The first reflector can also extend forward and above the optical axis in an inclined manner from a first side to a second side so as to reflect part of light emitted from an upper part of the LED light source with respect to the optical axis. A second reflector can be disposed substantially in parallel to, and below, the first reflector. The second reflector can be configured to reflect light from the first reflector. A third reflector can be disposed in front of the LED light source and downward with respect to the optical axis. The third reflector can extend forward and below the optical axis in an inclined manner from the second side to the first side so as to reflect part of light emitted from a lower part of the LED light source with respect to the optical axis. A fourth reflector can be disposed substantially in parallel to, and above, the third reflector. The fourth reflector can also be configured to reflect light from the third reflector. |
