A night lamp is a device that is used not only for illumination in the dark, but also as a decorative element. It helps to create an atmosphere of coziness and comfort in the room. You can find different nightlights in lighting stores, but you can also make them yourself. LED night light can be made from various improvised materials - music discs, paper, glass, fabric. The most important thing is to select and create an electronic circuit.
Advantages of LED night light
LED nightlight is quite simple. The scheme is not difficult even for inexperienced people. The advantages of an LED light source include:
- low power consumption;
- long term of operation;
- availability;
- variety of application patterns;
- quality of light;
- good lighting;
- lack of heating;
- safety.
A homemade LED night light can be used for lighting, allowing you to navigate in the dark. The device can be installed in any convenient place.
Types of fixtures
All LED night lights can be divided into two groups according to the method of nutrition. These include:
- Standalone. Run on battery or battery.
- Stationary Plug in socket.
Autonomous products can be moved and put in any convenient place. Disadvantages include waste on batteries that need to be changed periodically. A model that receives electricity from a wall outlet can only be installed near a power point. On such a lamp you do not need to buy supplies.
Nightlights with motion sensor
Devices can be equipped with various sensors that facilitate ease of use. They do not need to be included, they are activated independently. It is not recommended to put such nightlights in the room, as they can record any arbitrary movement and turn on. Usually they are installed in pantries, garages, hallway. The sensitivity of the sensor can be adjusted so that there are no false positives on pets. The range is 3-5 meters.
Wooden nightlight
This type of night lamp is completely safe. The tree is processed in such a way that there is no emission of harmful substances when heated. Wooden LED nightlights are even put in the nursery, as they are durable, environmentally friendly and difficult to break.
Built-in models can be placed in home decoration or furniture. Used for decoration. The disadvantages include the fact that over time, the backlight in one place can get bored, and it’s difficult to remove the built-in light source.
Necessary materials
To create a nightlight, you need to purchase LEDs or a matrix of diodes. The quantity is selected according to personal preference. It is better to buy bright multi-colored LEDs. The current strength of each component should not exceed 20 mA.
You will also need to buy resistors. To create a series-connected circuit, you need 1 current-limiting resistor. If the circuit is serial, all diodes must have the same rating. When wiring a parallel connection to each LED, a resistor is selected.
You will also need a semiconductor diode and a plug to connect to the network. An old disk, a bottle and other objects made of different materials can act as a case. The case can be assembled independently.
Of the tools you need a plastic plate, screwdrivers, knife, heat shrink tube, soldering iron, pliers.
Simplest scheme
When creating a do-it-yourself night light on LEDs, you need a powerful 1W white LED. The circuit is transformerless, stable and does not overheat. To ensure normal operation, you need to choose a capacitor of 250-630 with a capacity of 1 μF. The LED is soldered through a current limiting resistor. Of the 4 rectifier diodes, a diode bridge is assembled. The recommended current strength of each component is 1 A, the reverse voltage is at least 1000 V. An example of such diodes is 1N4007.
The whole circuit is mounted in the body using hot melt adhesive.
Build algorithm
First of all, you need to solder the circuit from LEDs, resistors and other components. After soldering, the contact points must be insulated with heat shrink.
Next, the body of the future lamp is going to. Inside should be a circuit. The case can be made of any improvised materials. For example, transparent plastic elements from boxes of CD discs are suitable. They are glued together with durable glue, and a disk is placed on the bottom so that the light from it is reflected. The entire structure must be degreased with alcohol. Optionally, you can stick the legs to the assembled lamp.
For the bedroom, a fan on the fan is perfect. You need to buy a large fan and attach a soldered circuit to it.
Near the bed you can put a LED night lamp, made by yourself in the form of a rug. To make it, you don’t even need to solder - just buy a matrix of LEDs and weave it into the carpet.
Night light starry sky"
Such a nightlight imitates the night sky with constellations. For the manufacture you will need a glass jar with a lid, foil, awl, scissors, LED flashlight and a tray.
On the foil, you need to draw the sky with the stars in any order that the master wants. The sheet must be put on a flat surface and with an awl make holes for the stars. The foil is cut to fit the height of the can. The paper is folded into a tube and placed in a jar. Down the cans is put a flashlight. When you turn it on, you can observe the glow from the nightlight on the walls and ceiling.
In the same way, you can make a nightlight with your own hands from LEDs and a can. You need to paint it, remove all the stickers and make holes. A candle, a lantern or a garland is placed inside.
Moon Night
You will need an LED strip and 2 transistors. They will adjust the device and turn on / off the board.
To make a nightlight out of plywood with LEDs in the shape of the moon, you need a sheet of plywood, which is cut out in a circle. A printed image of the moon must be glued on top. Then you need to drill 2 holes for fastening and pulling wires. The base of the lamp is glued to the plywood. After drying, an LED strip is glued around the perimeter.

Night light from an electric plug or fumigator
You will need LEDs, 2 resistors, 2 capacitors, a zener diode, a heat shrink tube.
Grounding contacts are removed from the plug. You also need to remove the clamp and grind the rim on the LED using the needle file.
Similarly, a nightlight is made from the fumigator. It must be disassembled, remove the heating element and put the LED on a free space. The voltage passes through the capacitor. A rectifier bridge is placed at the output, which smoothes the ripple and evens out the voltage.
You can put on a plug on the plug, which is made independently or purchased in a store.
How to choose a purchased nightlight
If there is no way to make a lamp for your own home, you can buy it in a store. The range of goods offered is wide, but you need to be able to understand the characteristics.
Do not take too cheap models. They are made from substandard materials and may be unsafe. Also, do not take too bright devices with a neon color.They are usually made from harmful materials.
A lamp in the form of a toy, a sun, a star, a fairy-tale character and other original form is suitable for a children's room. It is better to take the device from high-quality plastic and wood. A durable night lamp made of plexiglass and LEDs is also suitable.
It is necessary to decide in advance in which place the lamp will stand. It should fit into the interior and complement it. It is desirable that its design be similar to the style of other lighting fixtures in the room.
The color is better to take a white night light. Eyes will not get tired of him, and he will successfully fit into any interior of the room. It can be installed both in the nursery and in the bathroom.
