Frequently Asked Questions About LED Driver Power Supplies
What is the difference between an LED driver and a power supply?
An LED driver is designed around LED load behavior and often regulates LED current. A general power supply commonly focuses on maintaining a defined voltage. The required architecture depends on the LED module.
Should I use a constant-current or constant-voltage LED driver?
Use the configuration required by the LED load. Integrated LED modules frequently require regulated current, while some LED products include their own downstream current regulation and use a constant-voltage supply.
How do I choose the correct LED driver current?
Follow the LED module or LED manufacturer's rated operating current and thermal limits. Constant-current regulation is commonly used to prevent excessive LED current and maintain predictable output.
How do I select LED driver voltage?
Determine the minimum and maximum forward voltage of the complete LED string at the required current and ensure that range is compatible with the driver's regulated output range.
Can I use a higher-wattage LED driver?
Potentially, provided the driver's current, voltage range, control method and application requirements remain compatible. Wattage alone does not determine suitability.
What does PWM dimming mean?
PWM dimming controls LED brightness by rapidly switching the LED current on and off and changing the duty cycle. TI documents PWM as a common LED dimming technique.
Why does LED driver temperature matter?
Higher temperature can increase stress on power electronics and other components. The driver should therefore be evaluated inside or under conditions representative of the final luminaire.
Can LED driver electrical parameters be customized?
Depending on the existing platform and technical feasibility, project-specific electrical requirements can be evaluated. Bolanda reviews input/output requirements against the selected electronic power product and application.
Can cables, labels and packaging be customized?
Bolanda currently lists connector and cable, housing and label, and packaging among its OEM/ODM project configuration areas. Final feasibility depends on the selected product and order requirements.
What should I send before requesting an LED driver quotation?
Provide LED current, voltage range, maximum power, input requirements, dimming requirements, operating environment, mechanical size, connector/cable requirements, target market, estimated quantity, and any OEM requirements.
