The specific embodiment
Cooperate and to consult Figure 1 and Figure 2, be schematic diagram according to the reflection type bicycle lamp device of the switchable light projection distance of a preferred embodiment of the present invention.This reflection type bicycle lamp device can be with on ray cast to a road surface that it sent.
This reflection type bicycle lamp device comprises a pedestal 10, a reflector 12, one first luminescence unit 14, one second luminescence unit 15, and a luminous controling unit 20.
This pedestal 10 has a horizontal part 101 and a vertical component effect 102, and this vertical component effect 102 is extended downwards by this horizontal part 101.
This reflector 12 is arranged at the lower surface of the horizontal part 101 of this pedestal 10, and cooperates with this pedestal 10 and to define an accommodation space 40, and an opening 50 that communicates with this accommodation space 40.This reflector 12 has a reflecting surface 121 that faces this accommodation space 40.This reflecting surface 121 is a concave surface, preferably can be a sphere, a parabolic or ellipsoid.
This first luminescence unit 14 is arranged at the lower surface of the horizontal part 101 of this pedestal 10, and is arranged in this accommodation space 40.This first luminescence unit 14 throws on this road surface via this opening 50 in order to the light that sends downwards and by the reflection of this reflecting surface 121 and forms one first surround.In the present embodiment, this first luminescence unit 14 is a light emitting diode, does not limit with this during actual enforcement.
