Q&A

• How does under-running LEDs contribute to the efficiency and longevity of lamps?

  Under-running LEDs increases efficiency and longevity, as demonstrated by an example of a modified lamp running for 50,000 hours at half a watt. The video also discusses the design and limitations of the Dubai lamp by Philips, emphasizing its non-dimmable nature and potential reasons for limited availability in other regions.

• How is power dissipation regulated in the efficient LED lamp?

  A circuit with zener diodes and high-value resistors is used to regulate and minimize power dissipation in the LED lamp. Connecting additional wires to measure voltage across zener diodes also reveals effective regulation and tuning of the circuit.

• What components and processes are highlighted in the manufacturing process of the electronic circuit?

  The manufacturing process involves wire bonding onto the circuit board, and the schematic analysis includes capacitors, resistors, transistors, and zener diodes. The video also discusses the use of a linear current regulator to ensure stable LED operation. Additionally, controversial aspects of electrical testing in the UK are touched upon.

• What does the reverse engineering analysis of a lamp circuit reveal?

  The reverse engineering analysis shows an odd design with duplicate components and active circuitry. The circuit uses a capacitive dropper with additional current regulation. Furthermore, the lamp contains multiple filaments, each running at low current and consisting of 21 flip chip LEDs.

• What are the challenges for architects concerning the introduction of new LED lamps?

  Architects face limitations on lamp options and color rendering index due to the introduction of new LED lamps with higher energy efficiency and longer lifespan. They also encounter issues related to cost and color temperature preferences in different regions.

• What is special about the Philips lamps exclusive to Dubai?
