LEDs Expertise

From 0.1W LED to 20W LED, we can identify the most suitable solution for your needs.

• An LED with a high Color Rendering Index (CRI or CRI) improves the rendering of your lighting. Example: a good CRI (> 93) allows the eye to differentiate between veins and arteries.
• Conversely, an LED with a low CRI (<70) improves the light power (and therefore the lumen / watt output) of your lighting.
• LEDs with CRIs adapted according to the elements to be illuminated. Example: LEDs for food, to highlight pastries, fish, or red meat ...
• RGB LEDs, see RGBW (Red Green Blue, White) allowing you to implement variable colorimetric lighting solutions.

The particularity of LEDs is that they have a very high power density per mm², or even higher with technological developments. This can lead to a sharp reduction in the lifespan of the LED if the thermal chain has not been correctly sized.

Example, white LEDs lose 10% of flux (compared to 25 ° C) when their junction temperature is at 100 ° C. For a red or amber LED, the flux loss will exceed 50%!

Our electronic and mechanical development team is experienced in choosing and sizing the right solutions, whether through:

• The selection of the right PCB (SMI, FR4 via thermal, PCB glued on thermal drain, Chip On Board (COB))
• Passive dissipation (commercial heatsinks, custom-developed heatsinks, evacuation via product mechanics, etc.)
• Active dissipation (fans, heat transfer system, Peltier system, etc.)
• Thermal interfaces (pasta placed in a robot or sheets positioned by hand)

Depending on your needs, we will use the appropriate optical system, either commercially available or developed by our network of partners

Driving LEDs optimizes color performance, your lighting system's efficiency and price.

Depending on your needs, we can drive the LEDs in

• Constant current switching (high price, high performance in colorimetry and efficiency)
• Linear constant current (average level, average performance)
• Passive (lowest price, lowest performance)
• Note: see to put a double entry scale (price, performance)

We can also support you on the overall system by offering you intelligent control solutions via DALI, DMX, CAN, Bluetooth communication buses.
We have also developed our own algorithm for optimizing the driving of RGB LEDs, which adapts to the operating temperature and BIN of each chip.
