DE931214C - Circuit for parking lights on motor vehicles - Google Patents

Description

The invention relates to a circuit for parking lights Motor vehicles in which the parking lights and tail lights on the vehicle can be used as parking lights on the side facing the traffic.

Parking lights on motor vehicles provide sufficient lighting of parked vehicles during the dark, with the least possible expenditure of electrical power, taking into account the already overloaded batteries of is of great importance. The Stramverbraweh for parking purposes in each headlight of the vehicle. Built-in parking lights that can only be switched in pairs must be uni'rtischaftUch, since it is sufficient and also permissible to use the parked Only illuminate vehicles on the side facing the traffic and therefore endangered. One has therefore already gone over to separately attached at a suitable point Use lighting fixtures that are white at the front and red at the back abisitranlen and which are only put into operation on the vehicle side, which is exposed to traffic. This results in a considerable reduction in power consumption or a corresponding extension of the parking time with the same service expenditure achieved.

The invention avoids the use of separate parking lights, which are usually bad afterwards in the structure of the motor vehicle anyway insert. It uses the parking lights and tail lights built into the motor vehicle using a specially designed switch and circuit that Here, too, it is permitted to only use the lights on the side facing the traffic in To put operation. The electricity savings already achieved are also here thanks to the unilateral operation fully effective. Circuits in which either only the left front parking light with the left rear taillight or just the right one Front parking light switched on with the right rear taillight light as parking lights have already been proposed. The subject of the invention is another Design of the parking light switch and the resulting circuit. The parking light switch is also here according to the invention in such a mechanical manner with the main light switch coupled that prevents unauthorized start-up wild.

The proposed circuit is shown in the drawing below Omission of all elements that are unimportant for the mode of operation. S i is the one according to the invention Switch to operate the parking lights serving as parking lights. With S2 is the light switch available for normal operation of the parking lights in the motor vehicle designated. L i is the pair of parking lights and taillights on the left, L2 the corresponding one Pair on the right of the vehicle, with either L i or L2 also the license plate lighting can be coupled.

The switch S i has two sets of contacts K i and K 2 coupled to one another and three positions. The middle position shown in the drawing means the off position. The circuit is open in contact set K i, while contact set K2 keeps both circuits Li and L2 closed. The parking lighting is therefore out of order. If the switch S i is placed in position a, the contact set K z closes the circuit, while K 2 opens the a contact and keeps the b contact closed, so that the circuit for the pair of lamps L i on one side of the vehicle is closed and the lamps L i light up. By moving the switch Si to the b position, the circuit K i 'is closed again. In this case, contact set K: 2 opens contact b and keeps contact a: closed, so that the circuit for the pair of lamps L2 on the other side of the vehicle is now closed.

The light switch present in every motor vehicle is coupled to the parking light switch S i in such a way that it can only be actuated when S i is in the off position, which means that the headlights cannot be switched when the parking light is switched on. When the switch S i is in the off position, the contact set K i can be bridged by the standing lamp part S2 of the light switch. The contact set K2 keeps both contacts a and b closed in this off position, so that both parking lights can be switched together with the normal light switch via the parking lamp part S2.

Claims (3)

PATENT CLAIMS: i. Switching for parking lights on motor vehicles, in which the parking lights and tail lights on the vehicle are only switched on serve as parking lights on the side exposed to traffic, characterized by that to operate the circuit, a switch (S i) with three positions and two Coupled contact sets (K i and K 2) is used. 2. Circuit according to claim i, characterized in that the contact set (K i) depending on the position des. Switch (S i) keeps a circuit open or closes while the contact set (K2), depending on the position of the switch, keeps two circuits closed or one open and keep the other closed. 3. Circuit according to claim i and 2, characterized characterized in that the light switch (S2) of the motor vehicle with the switch (Si) for parking lights is coupled in such a way that the former only operate can when the switch (S i) for parking lights is in the off position.
