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.
