Definitions

• handlebar mounted bicycle lights employ a light emitting diode (LED) to generate light.
• the LED is generally contained in an opaque metal or plastic housing that, when the light is mounted to the bicycle, will shield the rider's eyes from light.
• the light housing will include a transparent portion in the front to allow light to be emitted generally forward.
• Some lights have more complex designs that include mirror and lens elements that reflect and focus the light in a specific direction, or give a predetermined intensity distribution, or form an image or pattern.
• the lens elements can be separate or included in the transparent portion of the light housing and the mirror elements are usually situated rearward and to the sides of the LED in order to reflect and focus the light forward and out through the transparent portion or lens.
• the present invention provides a unique and distinctive light pipe design mountable to a bicycle handlebar and stem.
• the light is preferably dimensioned so that it can be positioned between the brake levers and extending in line with the handlebar.
• Most bicycle handlebars are formed from metal, and are connected to the front steering fork of the bicycle by a "stem.”
• the stem is generally made from metal or carbon fibre and has a clamp arrangement at either end allowing the stem to connect the handlebar rigidly to the bicycle front fork steerer tube by the clamping arrangement.
• the stem generally extends forwardly and upwardly from the upper end of the steerer tube, with the handlebar mounted across the forward end of the stem.
• the form of the handlebar and stem connection is roughly and generally a "T" junction.
• the light pipe assembly is held central and longitudinally in line with the handlebar by upper and lower cover parts of the housing which enclose at least an end of the stem adjacent the handlebar, and a portion of the handlebar between the brake levers.
• the lower cover has a generally "T" section so as to be able to be fitted to a standard bicycle stem and handlebar connection and the upper cover is generally a mating half of the lower cover so that, when the upper and lower covers are fitted they form a housing which encloses at least the end of the stem and the part of the handlebar between the brake levers.
• the upper and lower covers may be moulded from plastics material and may be fixed together by fixings such as screws or bolts.
• the light pipe assembly includes, for each LED, a respective heat sink for conducting heat away from the LED.
• the heat sinks of the LEDs are held in contact with the handlebar, which is usually formed from metal, so that heat can be conducted away from the heat sinks by the metal handlebar.
• FIGURE 2 is a perspective view of a bicycle light of the invention seen from the front and one side, showing the light pipe assembly and the housing mounted to a handlebar of a bicycle;
• FIGURE 4 is a sectional view of a handlebar and handlebar stem showing the housing and light pipe mounted thereto;
• FIGURE 9 is a vertical cross section to an enlarged scale of the light pipe assembly of Figure 6;
