Close up wiring compartment.

Philips led bulb schematic. But the problem in all models is the circuit lights up clearly for 3 4 hours. The heart of the circuit is a pt4554d high precision non isolated step down led constant current ic. The above design lacks a genuine surge protection feature and therefore could be severely prone to damage in the long run in order to safeguard and guarantee the design against all sorts of surge and transients.

All leds white 5mm straw hat type input 220 120v mains. I changed the components many time including the 1n4007 diodes with several makes. Partial trace of the schematic of the bulb.

I created the circuit in 4 common pcb s with 4 5 6 led s. The philips bulb basically consists of the pcb and led plate along with the snap together plastic case which also supports the contact foot. The basic principle behind the 230v led driver circuit is transformer less power supply.

The main component is the x rated ac capacitor which can reduce the supply current to a suitable amount. The foot contact attaches to the pcb on the philips bulb with wiring visible here. Xrepeat steps 3 to 5 for each additional bulb ballast based on illustration below.

Luminaire description philips led t8 tubes are suitable to be installed in t8 or t12. Then it become fade. Circuit n neutral wire.

Schematic diagram of the 12w led light bulb. Install led t8 tube. The ic has an integrated 500v power mos and requires only a few peripheral components which.
