Do you know why headlamps lighting are banned in some countries?The kosoom experts are here to tell you

LED headlamps are banned for the following main reasons.

  • 1.the light is too strong.

LED headlights emit too much light, easy to cause dazzling and visual fatigue of other road users, affecting traffic safety. Many countries and regions have strict limits on the maximum brightness of car headlights.

  • The main measures to solve the LED headlamp too much light are.

  • reduce the luminosity.

  • Adjust the luminosity of the LED headlamp to meet the standard range, usually each country and region have strict regulations on the maximum brightness of the headlamp.
  • Use optical filters.

  • The installation of optical filters can be LED headlamp light absorption and attenuation, it will be adjusted to meet the standard brightness.
  • Adjust the LED layout.

  • Reasonable arrangement of LED headlamps using the number of LED light sources and the location of the layout, you can avoid excessive focus of light to produce too high brightness.
  • choose the right angle of light LED.

  • choose 120 degrees or a wider angle of the LED, its light-emitting characteristics can produce a softer and more uniform light, to avoid excessive brightness.shopily981a9dde 8caa 4ef3 822b 9240e095989d 1024x1024
  • improve the shape of the beam.

  • Improve the optical design of the LED headlamp, which can make it produce a more standard beam shape, including beam intensity distribution, to avoid excessive concentration of light
  • 2.color does not meet the traffic regulations

  •  the color of the light is not in compliance with the local traffic regulations, generally for yellowish light or white light. If the light color from the LED headlamp is too light or too dark, it will also be considered non-compliant and prohibited from use.zoomable led track lighting 1280x670 8f0cf9e4 3188 4fe3 962c 859f1eb91008 1024x1024
  • 3.uneven distribution of light

  • LED headlamps emit light if the range and intensity of uneven distribution, easy to cause glare in a particular angle, will also affect driving safety and is prohibited.

The main measures to solve the LED headlamp too much light are.

  • 1. reduce the luminosity.

  • Adjust the luminosity of the LED headlamp to meet the standard range, usually each country and region have strict regulations on the maximum brightness of the headlamp.
  • 2. Use optical filters.

  • The installation of optical filters can be LED headlamp light absorption and attenuation, it will be adjusted to meet the standard brightness.
  • 3. Adjust the LED layout.

  • 4. choose the right angle of light LED

  • choose 120 degrees or a wider angle of the LED, its light-emitting characteristics can produce a softer and more uniform light, to avoid excessive brightness.
  • 5. improve the shape of the beam

  • Improve the optical design of the LED headlamp can make it produce a more standard beam shape, including beam intensity distribution, to avoid excessive concentration of light.
  • 4. axial luminosity is too low

  • the axial luminosity of the LED headlamp (i.e., straight ahead of the luminosity) to meet the minimum requirements of local regulations, if too low will not be able to illuminate the road ahead as required, affecting the safety of night driving, and is therefore prohibited.
  • 5. the filter pattern is not compliant

  • the beam pattern generated by the optical filter used in LED headlamps should meet local regulations. If the beam pattern does not meet the requirements (such as shape, size, red and blue ratio, etc.), it will also be considered non-compliant and prohibited.
  • 6. poor anti-glare performance.

  • LED headlamps in the design and production of anti-glare performance to be considered, if the other road users (including meeting, following, head-on vehicles, etc.) poor glare performance, will also be prohibited for traffic safety reasons.shopilyc1d7aff2 d12f 44d7 acad 110b2739d529 1024x1024
  • 7. poor EMC performance,

  • LED headlights need to have good EMC performance, can not produce interference with the vehicle electronic system. If the EMC performance is poor, there is strong electromagnetic interference, will also be banned for affecting the safety of the vehicle.
  • The main effects of poor EMC performance of LED headlamps are.

  • 1. interfere with the electronic systems.

  • electromagnetic interference generated by LED headlights can affect the vehicle’s engine electronic control system, ABS anti-lock system, navigation and positioning system, audio system, etc., causing the failure or misoperation of these systems.
  • 2. affect the wireless communication.

  • LED headlights generated electromagnetic interference can also affect the normal work of wireless communication devices such as Bluetooth, WIFI, car monitoring system, resulting in abnormal communication.
  • 3. car anti-theft system false alarm,

  • LED headlights of electromagnetic interference can also be false triggers car anti-theft alarm system, resulting in false alarms.
  • 4. Affect the car key remote control.

  • Some models use smart keys for remote control of door locks, start and other functions, and the electromagnetic interference of LED headlights can also affect the normal work of the key remote control.
  • The main methods to improve the EMC performance of LED headlamps are.

  • 1. choose good quality LED and electronic components.

  • High-performance LEDs and electronic components usually have better anti-interference ability to reduce the interference from the source.
  • 2. Increase the filter circuit.

  • In the LED headlamp driver circuit to increase the filter to inhibit the generation and transmission of high-frequency pulses and noise.
  • 3. ensure a good grounding connection.

  • the LED headlamp housing to achieve a reliable grounding connection with the whole car housing to prevent interference from leakage current. 4.
  • 4. reasonable layout of the circuit

  • the circuit board of the LED headlamp for reasonable layout, input and output lines to maintain a certain distance between each other to avoid mutual interference.
  • 5. Conduct EMC test.

  • Conduct strict EMC test during the R&D and production of LED headlamp to find the source of interference and repair it to ensure the final product meets the EMC requirements of automotive standards.
  • 6. Increase shielding measures.

  • Adopt shielding and absorption measures inside the LED headlamp, and suppress the transmission of interference signals through shielding cover and shielding tape.

At lastly In short, only LED headlamps that comply with local traffic regulations, in terms of luminosity, light color, light distribution, visual effects and other standards, and good EMC performance, will be legally approved for use. If the use of unapproved LED headlamps will face the risk of being banned.If you still want to know about the lighting safety of led downlights, welcome to contact us
