Requirements according to the regulations

The luminous intensity of daytime running lights depends on the beam angle of the LEDs with the lenses installed. Diodes without optics shine 120 degrees, that is, in all directions. Therefore, focusing the light is required, as in a flashlight. Therefore, the requirements indicate the luminous intensity in Candelas, not lumens. To measure the light intensity, place a lux meter in front of the DRL at a distance of 1 meter. The lux meter must be positioned strictly along the optical axis of the light source. Thus, the Luxes will turn into Candelas, by which the effectiveness of work can be assessed.

Required characteristics:

each DRL should have 500-700 lumens;
power from 6 Watt;
shine at an angle of 35 degrees.

Simply put, if the power is below 6 watts, then it is junk, not DRL.

Requirements according to GOST:

luminous intensity 400-800 candelas;
glow angle 25 degrees vertical;
angle 55 horizontally;
The luminous area of each is at least 40 square centimeters.

On packages with DRL there are often inscriptions like “install it and you will become very visible”, but inside there is junk with a power of 2 Watts. And of course, the Chinese help, who write super-bright LEDs, powerful COB, super-powerful on any junk.

I advise everyone to go through any Chinese budget LED lighting equipment immediately after purchase. This will eliminate assembly defects, apply thermal paste and improve cooling.

Connection via a 4-pin relay from a generator or oil sensor

The following two methods have a common basis and imply the operation of daytime running lights only after the engine is started. The circuit for switching on DRL from the generator is based on switching a four-contact relay and a reed switch.

The DRL relay contacts are connected as follows:

30 – to the positive terminals of LED modules;
85 – to the positive wire to the dimensions;
86 – to any reed switch output;
87 and the second terminal of the reed switch - to the “+” of the battery.

After checking the reliability of all contacts, proceed to setup. To do this, start the engine and, by moving the reed switch near the generator, achieve its activation and a stable glow of the DRL. Then the reed switch is hidden in a thermal tube and fixed in the found place using nylon ties.

DRL in the far to the floor glow on the controller

On the Internet there are many circuits and devices for high beam DRLs at full heat for 12 volts, but few for 24 volts, and most of them are complex. Below we will look at the long-range DRL controller in full heat; circuits for 12 and 24 volts will be provided. And it will be controlled by an inexpensive and accessible Attiny13A controller.

Pros of DRL:

You don’t have to constantly think about what you didn’t forget and turn on the lights when the car is moving. It turns on automatically.
After the trip, you don’t need to think about turning off the lights, the DRL unit will do it for you.
The lamps turn on smoothly, and not at full power, and this saves electricity, reduces the load on the generator by five times, and means saving fuel.
The lamps will last much longer.
When the ignition is turned off, the DRL unit does not consume energy; the unit is turned off.

Principle of operation:

When the ignition is turned on, power is supplied to the DRL circuit.
The controller gives a delay of 10 seconds.
The controller waits until the status on port PB3 is zero. Simply put, the controller will check whether the dimensions are turned off. If they are turned off, then it moves on. If not, waits for shutdown.
The input status of the PB4 port controller is checked. That is, it waits until one appears. Simply put, this port is connected to the handbrake and it controls the state of the handbrake. The handbrake was lowered, a 1 appeared on port PB4
The lights are turned off and the car is released with the handbrake, only then the high beam headlights begin to light up smoothly.
The DRLs turn off smoothly when the parking lights are turned on or the parking brake is applied.

Adjustment.

By default the block is set to 30%.

The brightness of the DRL is adjusted using a button located on the board and recorded in non-volatile memory.

To enter the setting mode, you need to press the adjustment button and hold until the headlights blink twice. We have entered adjustment mode. Each time you press the button, the brightness of the high beam headlights will change stepwise until it reaches maximum.

The next press - the headlights will go out, and pressing further the headlights will burn brighter each time. If you have reached the desired brightness, you need to write the new settings into memory, otherwise after rebooting the controller will install the old settings.

To do this, press the button and hold until the headlights blink twice. This will serve as a signal that the new settings have been saved.

Here we will also consider DRLs for cars with an on-board network of 12 and 24 volts.

The difference between 12 and 24 volts, DRL will only be in the circuit itself. A zener diode will be added to limit the voltage at the transistor's gate, and the rating of some components will be changed to 24 volts. The firmware and operating algorithm of both schemes, as well as the connection to the vehicle network, are identical.

Option No. 2

For assembly you will need 1W and 3W LEDs in the amount of 5-7 pieces per 1 block. It is impossible to set less than 1W, the light intensity will be too low and will not fit into the requirements. The basis will be an aluminum profile or an aluminum ruler with places for mounting diodes. 1W or 3W LEDs are installed on aluminum using thermally conductive adhesive.

For LEDs, a wide range of optics are sold with different luminous angles, from 10° to 90°. Lenses of 30° - 35° are required; a separate lens is installed for each LED.
