The author of the video attempts to create an "eternal" LED lamp by modifying a non-functional LED light bulb. The author identifies overheating as the primary cause of LED lamp failure and decides to reduce the current to the LEDs to prolong their lifespan. To achieve this, they add a diode bridge and a capacitor to regulate the current.
The author then compares the modified lamp to a regular 7-watt LED lamp and finds that they have similar brightness, but the modified lamp has significantly lower heat emission (54°C vs 85°C). The author concludes that the modified lamp can potentially last "forever" if the current is reduced and overheating is prevented.
Here are the key facts extracted from the text:
1. The author is attempting to create an "eternal" LED lamp by modifying an existing lamp.
2. The author notes that the service life of LED lamps is often overstated, citing examples of lamps with claimed lifetimes of 25,000, 30,000, and 15,000 hours.
3. The author has a lamp that is supposed to last 27 years, but only lasts a few months.
4. The author decides to take apart a lamp that is no longer working properly to investigate the problem.
5. The author uses a hammer and a soft object to gently pry open the lamp.
6. The author finds that the LED is no longer working properly and decides to replace it.
7. The author notes that LEDs can last forever if they are not overheated.
8. The author decides to add a capacitor to the circuit to regulate the current and prevent overheating.
9. The author uses a diode bridge to convert the AC power to DC power.
10. The author adds an electrolytic capacitor to the circuit to smooth out the ripples in the power supply.
11. The author tests the modified lamp and finds that it shines with a power of 7.7 watts.
12. The author compares the modified lamp to a regular lamp and finds that they shine with approximately the same brightness.
13. The author measures the temperature of the lamps and finds that the modified lamp is significantly cooler than the regular lamp.
14. The author assembles the modified lamp and adds a heat shrink tube to protect the wiring.
15. The author adds a few drops of glue to the capacitor to secure it in place.
16. The author tests the modified lamp again and finds that it is still working properly.
17. The author recommends making similar modifications to other LED lamps to extend their lifespan.
