The Light Emitting Surface (LES) determines the beam angle and intensity. A smaller LES allows for tighter beam control with reflectors, while a larger LES provides softer, more diffuse light.
LED COBs, Engines, and Modules Component Intelligence
Engineered light sources for high-flux, thermal-managed, and precision-optical designs.
What are LED COBs, Engines, and Modules components?
LED COBs and modules consolidate multiple dies onto a single substrate to provide high-intensity, uniform light output. Selection hinges on thermal resistance, luminous efficacy, color consistency (MacAdam ellipses), and the specific mechanical footprint required for your heatsink.
How to Choose LED COBs, Engines, and Modules Components
Selecting the right light source requires balancing optical performance with thermal constraints.
Thermal Resistance
Lower junction-to-case thermal resistance is critical for high-power COBs to prevent premature degradation.
Color Consistency
Check MacAdam ellipse ratings to ensure uniform color temperature across multiple modules in a single array.
Luminous Efficacy
Evaluate lumens per watt (lm/W) at your specific operating current and junction temperature.
Optical Compatibility
Ensure the light-emitting surface (LES) size matches your secondary optics, such as reflectors or lenses.
Drive Current
Match the module's forward voltage and current requirements to your constant-current LED driver.
