Exploring the Basics and Working of Emergency Vehicle LED Strobe Lights

Strobe / flashing lights are an integral part of emergency vehicle LED lights that emit bright, concentrated flashes of light instead of a steady, continuous beam. In this blog, D&R Electronics Co. Ltd., a reputed fleet vehicles solution provider in Bolton, Ontario, explores the basics and working principles of LED strobe lights.

What Are Emergency Vehicle LED Strobe Lights?

Emergency Vehicle lights meet SAE Class 1 requirements of intensity, visibility, and other usage criteria. Class 1 must produce a minimum peak of 8,100 candela, often reaching 18,000 candela. flashing range of 60 to 240 flashes per minute.  And a visibility requirement of 500+ feet in direct sunlight. The purpose of these emergency vehicle LED lights is to grab the attention of other motorists across all environmental conditions, such as rain, fog, or sunlight. This bright and concentrated beam is then dispersed as per application requirements using appropriate lens optics and reflectors.

Here are two primary optics used in emergency lights:

- Total Internal Reflection Optics (TIR Optics): This type of strobe light focuses light into a tight beam for visibility across a long range. They are primarily used in highway response vehicles.

 
- Linear Spread Optics (LIN Optics): This type of strobe light diffuses light horizontally, ensuring broad coverage at intersections and work zones.

What Is The Working Principle Of Emergency Vehicle LED Strobe Lights?

The working principle of the emergency vehicle LED lights involves converting stored electricity into bright, intense flashes or pulses of light. The core components and functioning of strobe lights include:

- LED Modules: These include a collection of diodes, each emitting around 3 watts.

 
- Driver Boards: Helps control current, voltage and flash patterns.

 
- Optical Lens: Classified as TIR and LIN, optical lenses help amplify each signal to cover long distances or broad areas. 

 
- Sealed Housing: These are IP-rated housings made of aluminum bases that offer protection from dust, moisture, and weather exposure.

 
These components are combined to convert electrical signals to flashes of light of the required colour pattern and intensity.

Conclusion

To conclude, strobe lights are a key part of emergency vehicles as they emit bright, directed flashes of light.
