Do you add relays to car lights, and what relays do you add to LED lights for car headlights

Generally yes. A relay is an electrical component used on a circuit with a lower voltage or lower current to turn on or off a circuit with a higher voltage and a higher current.

It may be said that an electric switch is used to control a higher voltage or higher power circuit: a control current is given to the working coil of the relay, and the relay is engaged, and the corresponding contact is turned on or off. In power supply circuits, relays are also known as contactors.

Main role. Relays are automatic switching elements with isolation functions, which are widely used in remote control, telemetry, communication, automatic control, and mechatronics.

and power electronics, which is one of the most important control components.

Relays generally have an inductive mechanism (input part) that can reflect certain input variables (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.).

To do this, you must add a relay, one is that the original headlight line is not in accordance with your current design, so the original fuse will be overloaded, if the fuse is enlarged, it is easy to overheat or burn the line, which is very dangerous. The method is that the operation switch of the lamp does not need to be changed, and the relay added after it is still controlled by the original switch, so that it is more convenient to use it if it changes light, and remember that the power cord of the relay can not be the original headlight line.

First of all, I want to say, buddy, what you're doing is really inhumane! Did you still let the car on the other side drive? If you and I were to get in the car, I would drive right over to you!

However, if you usually run on the road is not indiscriminately shaking the opposite car, the problem still has to be solved, your light method is mainly to take power from the battery, you add so much power directly to the original car lights, it must be to burn the insurance, the correct way should be to take power from the battery, and install a light line group with a relay.

Plus relay is good for the line

Hello, I am happy to serve you, and make the following answer for you: to change the car headlights to LED lights need to add relays, relays are electronic components, used to play a control role in the signal circuit, it can receive a small current signal from the control circuit, and then control the current of the output circuit according to this signal, so as to realize the leakage function of the control electrical appliances Zen search shed. Steps to replace the LED light:

1. Remove the old headlights and remove the power plug; 2. Install the new LED lights on the body and install the power plug; 3. Install the relay, input the signal of the control circuit into the relay, and connect the output of the relay to the power interface of the LED lamp; 4. Check whether the LED light power supply is correct, if it is correct, the LED light can work normally. The reason for replacing the LED lights may be that the old headlights are malfunctioning, or they want to replace them with higher brightness lights. Workaround:

1. Check the old headlights to determine whether there is a fault; 2. Choose the right LED light, you can choose different types according to the space of the vehicle; 3. Install the relay, input the signal of the control circuit into the relay, and connect the output of the relay to the power interface of the LED lamp; 4. Check whether the LED light power supply is correct, if it is correct, the LED light can work normally. Personal tips: 1. Be sure to choose the right LED lights to ensure that they can meet the space of the vehicle; 2. Be sure to install a relay to ensure that the LED light can work normally; 3. Pay attention to the safety of the power supply during the installation process to avoid accidents.

The function of the headlight installation relay is to turn on or off the circuit with higher voltage and higher current. Take the commonly used automotive light control relay as an example, there are mainly three-pin, four-pin and five-pin control relays, etc., which are missing yards to control headlights, headlights and instrument lights, turning lights, rear lights, brake lights, reverse shift lights, fog lights, cabin lighting, etc.

The function of the light relay: it is used on the circuit with a lower voltage or a lower current, and is used to turn on or off the circuit with a higher voltage and a larger current.

Commonly used automotive lighting control relays are mainly three-pin, four-pin and five-pin control relays. Respectively control headlights, headlights and instrument lights, cornering lights, rear lights, brake lights, reverse lights, fog lights, cabin lighting, etc.

When the combination switch is turned to the ON gear of the headlight, the control system of the headlight relay (the magnetic field coil part) will be energized to generate a magnetic field, and the alloy contact will be closed immediately, and the current of the control system will be turned on, so as to control the opening of the headlight.

When the combination switch is turned to the headlight OFF gear to disconnect the power source, the magnetic field disappears so that the control alloy contacts are immediately separated, and the current of the control system is cut off, and the headlights are turned off.

At present, automotive control relays are still mainly mechanical, but they are developing towards solid-state relays. The key to relays is reliability, because if the relay fails, it will immediately cause the function of the system components to be paralyzed, and even the entire car will not be able to move. For example, if the starter relay fails, the car will not be able to start electrically.

Extended Information: Automotive Relay Installation Method:

1. Installation direction: If the direction of the installation is consistent with the direction of the relay's impact resistance, the performance of the relay can be fully exerted. It is recommended that the impact direction be perpendicular to the direction of movement of the contacts and armatures, which can effectively improve the vibration and shock resistance of the normally closed contacts in the non-excitation state.

When installing, the contact of the relay is axially parallel to the ground, which can avoid contact splashes and carbonization falling on the contact surface and improve the contact reliability. Multi-group relays should avoid small load contacts being located below large load contacts.

2. Close installation: When multiple relays are installed in close proximity, it will cause abnormal heating, and it is generally recommended to have a distance of 2mm. Polarity or magnetic latching relays installed in close proximity will affect the operating voltage.

Summary. Hello: It is not matching, specifically, it should be the contact of the relay (normally open) and the bulb in series, when the coil of the relay gets the voltage action, the normally open contact is turned on, and the lamp forms a loop, which is on.

Hello: It is not a matching god section, specifically, it should be the contact of the relay (normally open) and the bulb hole blind Bo Naxiang in series, when the coil of the relay gets the voltage action, the normally open contact is turned on, and the lamp forms a loop, which is lit.

For example, the car headlight relay is a small current to control the large current. The function of the automotive relay is to control the size and on-off of the current, the automotive relay is a kind of automatic control device that will change by leaps and bounds when the input amount (electricity, magnetism, sound, light, heat) reaches a certain value, and the output will change by leaps.

The automotive relay is composed of a magnetic circuit system, a contact system, a sail slag system and a recovery mechanism. The magnetic circuit system is composed of core, yoke, armature, coil and other parts. The contact system is composed of static reeds, moving reeds, contact bases and other parts; The original mechanism of the complex beam is composed of a restored reed or a tension spring.

A relay on the car can control two high beams in the hall, and the light relay is to control the light on and off according to the light intensity of the environment.

Jihehe Electric is an automatic switching element with isolation function, which is widely used in remote control, telemetry, communication, automatic control, mechatronics and power electronic equipment, and is one of the most important control components.

Relays generally have an induction mechanism (input part) that can reflect certain input variables (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.); There is an actuator (output part) that can realize "on" and "off" control of the controlled circuit; Between the input and output parts of the relay, there is also an intermediate mechanism (drive part) that couples and isolates the input quantity, processes the function, and drives the output part.

First of all, select the appropriate relay, first find the live wire of the headlight, cut it at a suitable position, connect the relay input (power supply) at one end, and connect the output end of the relay (headlight) at the other end; Headlight switch wire, connected to the control switch connector of the relay. That's it. The relay should be fixed in the place where the car body can catch the iron.

Relay (English name: relay) is an electrical control device, which is an electrical appliance that makes a predetermined step change of the controlled quantity in the electrical output circuit when the change of the input quantity (excitation quantity) reaches the specified requirements.

It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in the control circuit of automation, it is actually a kind of "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.

The purpose of pressing the relay is to make the headlights brighter, directly with the battery electricity, the control line of the original headlamp to do the control line of the relay.

Unplug the headlight relay and replace it with a new one.
