Abstract
A third brakelight is to apply the brake inertial mechanism to the production of brake proportioning effect by triggering the power source of lamp sets. This brakelight comprises a brake proportioning component and light emitted diodes or filament type bulb lamp sets. During a braking of the vehicle, a set of different length pendula may impact the printed circuit board having open circuits which are combined with pendula, served as switches. The stronger braking, the larger angle pendulum will swing while the vehicle is in motion. Thus, the more pendula impact the open circuits, the more lamps are ignited. And the driving safety of the vehicle can be promoted.
Claims3
A brakelight for a vehicle comprising:
- a plurality of lighting elements;
- a brake proportioning component including a plurality of pendula and a like number of silicon controlled rectifiers and resistors,
- said pendula each include a cylindrical body encircled by a conductive rubber ring, an arm of each of said pendula is supported by a movable frame which slides on a rail of a suspending beam fixed on a brake proportioning component main frame;
- each said arm of said pendula differs in length from each of the other arms of said pendula, each said pendula being otherwise identical in construction;
- a screw with a coil spring is mounted between said movable frame and said brake proportioning component main frame to enable a user to adjust a supporting point of each said pendula;
- a controlling circuit on a printed circuit board including a plurality of comb type open circuits, said comb type circuits being equal in number to the number of pendula, said comb type open circuits are connected to said silicon controlled rectifiers and said resistors;
- wherein
- when a braking force is applied to said vehicle, at least one of said pendula swings so that said conductive rubber ring contacts said comb type open circuit, thereby causing said controlling circuit to activate at least one of said lighting elements, the number of pendula that swing and therefore the number of lighting elements activated is proportional to the magnitude of said braking force.
