7 Watt Led Bulb Driver Circuit Diagram

The design can be adapted for all power leds ranging from 1 watt to 7 watt.

7 watt led bulb driver circuit diagram. These capacitors are connected line to line and are designed for high voltage ac circuits. Another interesting led circuit is the diy led light bulb. In this diy led light bulb the design of the led driver is very important. In this we designed an led light bulb and used it as a regular bulb.

The input mains 220v or 120v ac is half wave repaired by d1 and c1. C1 together with the inductor l0 and c2 make up a pie filter network for cacelling emi disturbenaces. 5 watt led driver circuit diagram 7 smps using cat6063 ic transformerless for easy 1 circuits build your own smart street lamp high voltage working and applications bulb 3 best you can make 5 watt led driver circuit diagram 7 watt led driver smps circuit cur controlled homemade projects three channel led driver circuit using cat6063 read more. But for this diy led light bulb we will be designing a transformer less power supply to act as the led driver.

The driver circuit divides a string of 25 leds into two sets of five one set of four and one set of six. In this circuit we will drive an led directly from 230v ac mains supply. Running a series circuit helps to provide the same amount of current to each led. The basic principle behind the 230v led driver circuit is transformer less power supply.

The main specifications of the driver circuit can be witnessed in the following. Generally we have two ways of designing the led driver. Using a switching mode power supply or a regular transformer based linear regulator. As indicated in the diagram 0 6 ohms will pass about 1 amp maximum current which becomes suitable for driving a 3 watt led safely and if a 5 watt led needs to be driven safely this resistor must be replaced with a 0 3 ohms which will allow a maximum of 2 amps of current.

The requirements of a lighting application often dictate what type of circuit can be used but if given the choice the most efficient way to run high power leds is using a series circuit with a constant current led driver. The circuit working of this 1 watt to 12watt led driver may be known as presented under. And the only way to change the. The main component is the x rated ac capacitor which can reduce the supply current to a suitable amount.

Led current in amps 1 25 r3 so for a current of 550ma set r3 to 2 2 ohms you ll need a power resistor usually r3 power in watts 1 56 r3 this circuit also has the drawback that the only way to use it with a micro controller or pwm is to turn the entire thing on and off with a power fet. 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. 230v led driver circuit principle.
