A.P.Electronics new Product Development Engineer Interview Questions, Process, and Tips

LED flickering can be resolved by checking power supply, using proper dimmer, and selecting high-quality LED bulbs.

• Check power supply for voltage fluctuations

• Use a proper dimmer that is compatible with LED bulbs

• Select high-quality LED bulbs that are designed to work with dimmers

• Ensure proper grounding of the circuit

• Avoid using too many LED bulbs on a single circuit

• Consider using an LED driver to regulate the voltage

• Che

The rough estimate of 100w and 50w FL depends on various factors such as the type of bulb, voltage, and lumens.

• The type of bulb used affects the wattage and lumens produced.

• The voltage supplied also affects the wattage and lumens produced.

• The lumens produced by a 100w and 50w FL bulb can vary depending on the manufacturer.

• A rough estimate for a 100w FL bulb is around 1600-1800 lumens.

• A rough estimate for a 50w FL bulb

Surges occur at outdoor LED lighting due to various reasons.

• Lightning strikes

• Power fluctuations

• Switching of high-power equipment

• Faulty wiring

• Poor grounding

• Inadequate surge protection

• Environmental factors such as humidity and temperature changes

• Overloading of circuits

• Electromagnetic interference

• Voltage spikes from the power grid

• Inrush current during startup

• Design flaws in the LED driver circuitry

CC LED driver maintains constant current output while CV LED driver maintains constant voltage output.

• CC LED driver is used for high power LEDs and ensures uniform brightness.

• CV LED driver is used for low power LEDs and ensures longer lifespan.

• CC LED driver is more expensive than CV LED driver.

• CC LED driver is more efficient than CV LED driver.

• CC LED driver is used in applications where LED brightness needs to be maint...read more

Surge protection device installation involves proper grounding and connection to electrical panels.

• Ensure proper grounding of the device

• Connect the device to the electrical panel

• Follow manufacturer's instructions for installation

• Test the device after installation to ensure it is functioning properly

Documentation process in LED lighting involves creating technical specifications, test reports, and user manuals.

• Technical specifications outline the product's features, performance, and compliance with industry standards.

• Test reports document the results of various tests conducted on the product to ensure its quality and safety.

• User manuals provide instructions on how to install, operate, and maintain the product.

• Othe...read more
