7 Watt Led Bulb Driver Circuit Diagram

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.

7 watt led bulb driver circuit diagram. In this we designed an led light bulb and used it as a regular bulb. 230v led driver circuit principle. In this circuit we will drive an led directly from 230v ac mains supply. 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. Another interesting led circuit is the diy led light bulb. 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. Using a switching mode power supply or a regular transformer based linear regulator.

Here is a 23v0v led driver circuit. The circuit working of this 1 watt to 12watt led driver may be known as presented under. But for this diy led light bulb we will be designing a transformer less power supply to act as the led driver. The main specifications of the driver circuit can be witnessed in the following.

Running a series circuit helps to provide the same amount of current to each led. The design can be adapted for all power leds ranging from 1 watt to 7 watt. This makes this 7 watt non isolated smps led driver circuit extremely compact durable efficient and very long lasting and also compliant with the present smps laws. Generally we have two ways of designing 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. 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. In this diy led light bulb the design of the led driver is very important. The input mains 220v or 120v ac is half wave repaired by d1 and c1.

These capacitors are connected line to line and are designed for high voltage ac circuits. It is very dangerous to use 230v ac supply on breadboard. 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.
