Introduction: Photo Frame Night Lamp
hi everyone today i will show you how to make photo frame as well as night lamp in one thing which look attractive in day for its photo frame feature and at night for its night lamp feature.
Step 1: Things You Will Required to Make This Photo Frame Night Lamp
the following things you will required to make this photo frame night lamp:-
1.full bridge rectifier circuit out of four diodes[IN4007][arrangement see in circuit diagram in next step]
2. 0.22mfd 400v to 630v non electrolytic capacitor
3. 1 M 0.25 watt resistor[colour code=brown-black-green-gold]
4. 22 ohm 1 Watt resistor[ colour code=red-red-black-gold]
6.colored tape for decoration
7.plastic container or so other container to make its casing
8. 25 hight bright 3.2 v, 200mA 5mm [any colour as per your wish,i uses white leds]
9.power cord with plug for main power supply in
10. 10K potentiometer [if you want to keep to adjuct brightness of the leds]
Step 2: The Circuit
the circuit for this project is been shown in the image as the main power supply on 240V AC in been send to the rectifier circuit through two resistor of 22 ohm[1watt] and 1M [0.25watt] an well as the capacitor is placed in between the rectifier input and the merging of the two resistor the voltage drop takes place.and after ac voltage drop the power is send to the full wave bridge rectifier circuit which is basically AC to DC converter using four IN4007 fast diodes.
later on the output of the full wave bridge rectifier circuit is send to light up 25 leds in series connection
the 10 k potentiometer will be connected in series with leds and circuit power output for leds.
NOTE:- THIS CIRCUIT USES AC MAIN POWER SUPPLY SO PLEASE DO NOT TOUCH ANY CONNECTION IN RUNNING CIRCUIT OR DO NOT CHANGE THE VALUES OF THE COMPONENTS OF THE CIRCUIT AS 25 NUMBERS OF LEDS SHOULD BE THERE MINIMUM OTHERWISE LESS THAN 25 LEDS WILL BURN ALL LEDS WHICH ARE CONNECTED TO THE CIRCUIT AND AFTER MAKING IT PLEASE SEAL IT IN THE CASING SO THAT IN RUNNING CIRCUIT NO NO WILL ABLE TO TOUCH .
Step 3: Making the Circuit and Assembling It in a Casing
as per the circuit shown in the above steps and instructions in the above steps make the night lamp and photo frame as shown in the image of this step.
after doing exactly i have instructed the image of this step is the image of final product and you project also look like this if you had done exactly i had said.
Step 4: Testing the Project.
now its the time to power on the plug and this wonderful photo frame nighr lamp will be lighted up with brightness of your work and looks beautiful in day as well as in night.
NOTE DO NOT TOUCH ANY CONNECTION WHEN THE POWER IN ON . I AM NOT RESPONSIBLE FOR ANY DAMAGE SSO PLEASE DO NOT TOUCH THE CONNECTION WHEN POWER IS ON.
