We at Shenzhen Smartware Technology Co Co. Ltd. make sure our products can withstand EMC - just let us know, this is one of your requirements.
Electromagnetic Interference (EMI) refers to a disturbance that affects an electrical circuit. Lights can both cause and be the victim of EMI issues in your vehicle. For this reason, it is important to have a basic understanding of standard EMI format and to look for lights that have been adequately designed and tested to reduce its effects.
The Five Types of EMI
There are five main types of EMI that you should be aware of:
▪ Radiated Emissions: Electromagnetic noise emitted by a light through the air that can interfere with other electronics (ex. cell phone, radio, etc.).
▪ Conducted Emissions: Electromagnetic noise conducted down a power line in a vehicle which can interfere with other electronic components in the vehicle.
▪ Radiated Immunity: The tolerance of a light to inbound electromagnetic noise in the atmosphere. Any broadcast signal (cell phone, radio tower, etc.) can interfere with a light if it is not properly designed. ▪ Conducted Immunity: The tolerance of a light to inbound electromagnetic noise conducted on vehicle power lines.
▪ Electrostatic Discharge (ESD): A sudden flow of electricity between two objects, such as when you shuffle your feet on carpeting and then touch someone to give them a shock.
Component Level vs. Vehicle Level
For OEM applications, lighting manufacturers focus on testing their products at a component (light) level. This is done to make sure that the lights will not cause a vehicle-level EMI failure or interfere with other electronics in the vehicle. OEMs then test at a vehicle level to ensure that it meets regulatory requirements.
Standard vs. Custom Products
At Shenzhen Smartware Technology Co Co. Ltd., we design and manufacture both standard and custom products. For custom products, we design, test, and manufacture to meet your exact specifications.
