Automatic Bathroom Light

This is a circuit of automatic bathroom light which can be used to automate the working of a bathroom light. It is designed for a bathroom fitted with an automatic door-closer, where the manual verification of light status is difficult. The circuit also indicates whether the bathroom is occupied or not. The circuit uses only two  ICs and can be operated from a 5V supply. As it does not use any mechanical contacts it gives a reliable performance.

Portable Electric Lamp cum LED Flasher

Here's the circuit of a portable type flasher uses 25W, 230V AC bulb and nine LEDs. The bulb and led's glows alternatively. The circuit includes a 555 timer based astable multivibrator which generates a square wave. This output drives the transistor bc547 to riger the gate of lamp controller triac.

Top 5 Automatic Light Circuits

Here's the list of top circuit diagrams of lighting circuits such as automatic emergency light, night light etc published on circuit sector

1. Automatic Night Lamp Circuit
This is a night lamp that turns on automatically when there is darkness in the room. Circuit is simple in design and uses very basic priciple of LDR.

2. LED Based Automatic Emergency Light
The white LED based low cost emergency light circuit diagram. six hours of battery back up - uses cheap components

3. Automatic Low Cost Night Lamp
Another redesign of automatic night lamp that reduces overall cost to build the circuit-perfect for hobbyists.

4. 20W Low cost Emergency Light
Simple emergency light circuit consist of 2 transistors, a transformer, 20 Watt fluorescent tube, 6V battery and some resistors and pots.

5. Fully Automatic Emergency Night Light
Rare circuit diagram that combines night light circuit with automatic emergency activation and
 overcharge protection.

Fully Automatic Emergency Night Light

There are already published diagrams for automatic emergency lights but this fully automatic led base emergency light has the following special advantages.

1. Fully automatic - The name suggests its character. The emergency light charging is fully controlled and you don't have to worry about over charging of battery.

2. The emergency night light - This circuit is designed to glow leds where there no light in the room and only when there is no mains supply available. If one of them are available, the leds will not glow and the power is saved. This is achieved by using LDR and a PNP transistor.So we can plug the emergency lamp on the mains socket overnight without the fear of overcharging or waste of energy.

20W Low cost Emergency Light

Here is simple circuit of a simple emergency light that can be constructed without much pain. The components of this circuit are 2 transistors, a transformer, 20 Watt fluorescent tube, 6V battery and some resistors and pots. the transformer of this emergency lamp doing a job of stepping up the voltage induced at its primary coil. But we use a 12-0-12 center tapped transformer for this purpose and the usual primary is used as secondary.

Strobe Light Circuit with Timing

Here is a strobe light circuit which has an option to set the flashing rate. Unlike other circuits here we use a Flash tube that usually use in flash cameras. In ordinary cameras, the flash may be work only after ten or twenty seconds. But in this circuit we can adjust flashing time by adjusting the potentiometer provided in the circuit.

Automatic Light Controller Using 7806 And LDR

This circuit controls the switching of the street light or porch light and it will be automated. This circuit of automatic lamp controller using 7806 regulator ic can be used to automate street lights, tube lights or any other house electrical lightning systems. the IC 7806 is a voltage regulator ic that give a steady output voltage against widely fluctuating dc input voltage.

Automatic Low Cost Night Lamp

The circuit of automatic night lamp published early is little bit costly. But this circuit of automatic  night lamp is perfect for hobbyists that it is uses very cheap components. It can be used as a bedroom light or a porch light. This night  lamp circuit can connect directly to 230 V ac and surprisingly it doesn't use any eliminators or transformers so the cost will be further reduced.

LED Based Automatic Emergency Light

Here is a white LED based low cost emergency light that offers high brightness, automatic activation, automatic charging with the use of cheap components. The circuit is very simple in construction and we can use the emergency light up to  6++ hours on battery feed.

Automatic Night Lamp Circuit

It is very convenient to light a lamp in our absense in the eving when it gets dark. This automatic night lamp circuit can be used to light staircase light, porch light etc automatically using domestic powersupply. It is very in expensive in construction and we dont have to employ or depend anybody to put on the lights when we are out of station. We can connect a CFL in place of filament lamp by making necessary alterations to the circuit.
