Pls post the circuit diagram for 9w 12v 750ma.
9 watt 9w led bulb circuit diagram.
It s likely though you ve already read the wikipedia page about series and parallel circuits here maybe a few other google search results on the subject and are still unclear or wanting more specific information as it pertains to leds.
Carefully remove the broken glasses.
The reference circuit for the microchip cl8800 is close to the circuit found on the 3m led bulb though the 3m bulb includes an additional rc network not shown here for phase dimming.
High watt led bulb using 1 watt leds and capacitor.
Schematic of 9 watt led inverter circuit shown below.

Seetharaman s words about the circuit.
We are a widely acclaimed manufacturer supplier trader and exporter of a wide series of led bulb driver.
The driver circuit divides a string of 25 leds into two sets of five one set of four and one set of six.
These capacitors are connected line to line and are designed for high voltage ac circuits.
A simple high power led bulb can be built using 3 or 4nos 1 watt leds in series although the leds would be operated only at their 30 capacity still the illumination will be amazingly high compared to the ordinary 20ma 5mm leds as shown below.
Few components available in the cfl pcb also can be used.
Cfl converted into led lamp.
Most of the components will be available in ones scrap box.
Circuit explanation the 9w led inverter circuit is an oscillator circuit which has a striking resemblance to the joule thief circuit.

Hopefully those looking for practical information on electrical circuits and wiring led components found this guide first.
Led bulb ic driver h p f.
The drivers we offer are precisely engineered under the guidance of adept engineers who possess rich expertise in this domain.
I am sending you a table lamp made from defunct energy saver lamp with broken tubes.
The basic principle behind the 230v led driver circuit is transformer less power supply.
The diagram is already presented in the above article which you can use but the leds will need to be 1 watt led 9 in series.
