The main focus is a commuter bike, but i don't want the light system to be limited to one style of bicycle. Basically I want to design a fool proof system that activates automatically, creates lots of visibility, and has nice atheistical value.

A rechargeable battery and solar cell would be cool too. When left outside, the battery could charge itself. Since many cyclists are environmentally conscious, I think it would be a good move to offer this, not to mention the convenience of not having to replace batteries. An auxiliary wall socket charger would have to be supplied as well for when solar recharging is not possible or would take too long. Some things that I like about my current headlight (Princeton Tec Switchback 1) that I would also incorporate are multiple settings: 3 intensity levels and a blinking mode; A high intensity Luxeon LED emitter and rechargeable Lithium Ion battery; A helmet mount as well as a bar mount; A coiled extension cord; car charger. Another feature that would be cool and I don't think any commuter light has is an audible low battery alarm. The light could also be made to switch into a power conservation mode when the battery is low. Hope this helps and good luck with your project. -Scott Last edited by hophead; 09-23-2009 at 03:36 PM. |

lighting
So why not consider the auto answer of low beam and high beam.
I used two systems on my bike one for a long range down the road and one bright and close range. I like the one on the helmet also because this can be pointed in direction of view without changing bike direction. Rear lights I still like the auto answer of a nice single red lamp to indicate location and the blinking yellow indicating hazard. The solid red indicator gives constant location and if on the outer left side of the bike helps drivers to pass safely because they can find the outer left side of the rider. A small DC generator can be added to the wheels to generate power to recharge the batteries. I like the one where it hits the center of the wheels to reduce pressure on the sidewall and a design that works well with higher speeds. 15 to 30 mph. instead of the 10 to 12 mph. Use of a voltage regulator to keep voltage stable and prevent burnout. Now with the advent of lithium light weight batteries we should see more of them and lower cost. Pro Audio speakers use a speakon connector to create a moisture resistant connction safely this might be adaptable and improved to weather proof. |
