About disassembling incandescent bulbs
From old lamps create vases and containers for spices, miniature aquariums and many other crafts.
If you decide to master this process, then you should start with an ordinary incandescent bulb. Inside it has no hazardous filling to the health in the form of additives from harmful substances. Therefore, its disassembly is not only simple, but also completely harmless to health.
Briefly about the device device
To begin dismantling the insides of the lamp, you need to familiarize yourself with its device. The main element is the body of heat, the ends of which hold the electrodes on themselves.
Additional stiffness is created by the holders fixed on the glass support - bead. The rod is connected to the leg, which consists of electrodes, a pingel, a plate.
The lamp and its leg. Components of the structure are: bulb (1), filament body (2), additional supports (3), rod (4), electrodes (5), paddle (6), intermediate conclusions (7), plate (8), shtengel (9), external conclusions (10), conclusions (11), base (12) (+)
All internal elements will have to be removed from the flask through its lower part.
How to disassemble
Here it is necessary to take into account some of the nuances, because will have to work with glass. The leg material is very thin, and the base of the insulator is rather coarse.
In order to prevent the fragments from flying away and the associated risks, a cardboard box should be used as a workplace. Its bottom is covered with soft material.
Before the operation, you need to arm yourself with thin-nose pliers. They can be used to dismantle the contact, firmly sealed at the neck of the flask.
The element is loosened and turned until the two wires leading to the main part of the lamp, the body of the glow, break off. Next, the released contact is removed.
The next task is to open the base isolation. This will require the same tool. With the help of fine-nose pliers, they swing the leg of a light bulb and remove it assembled with a plate, a power stick, electrodes, and a body of heat.
Having opened access to the internal cavity of the lamp, it is carefully cleaned with a piece of textile. Without insides from the bulb is only a heat-resistant glass bulb.
This is an example of using LN as a mini-greenhouse for growing small plants. This craft can be presented as an original gift.
How to apply it depends on your imagination - it can become a container for spices, a tiny aquarium, a lamp shade or a lamp.
For some crafts will be superfluous base. It is easy to remove, because the connection is not very strong. You can just hold it for a day in a mixture of hydrochloric acid with ammonium nitrate or in hydrofluoric acid. What will dissolve the glue, securing the base to the base of the flask.
With this option, it is important after the acid to thoroughly wash the product in a soapy solution. And do not forget to wear gloves to carry out all the manipulations.
This is how the contact retrieval process looks. It is captured by thin-nose pliers, well loosened, and then easily removed from the bottom of the cap
Another way is to unscrew the part at the point of contact with the glass, then remove the glue and remove the vessel. Sometimes it is enough to scratch the joint between the base and the bulb with a glass cutter to get rid of it.
Disassembling the lamp with a cartridge
With replacing light bulbs all sorts of trouble happen. It also happens that it is separated from the cap. In this case, do not disassemble the cartridge. Work requires the use of protective equipment in the form of glasses and rubber gloves.
Electricity is disconnected, convinced of the absence of voltage by using an indicator. Clean the fragments from the floor.
Further, they are armed with narrow-nose pliers and, rotating the base in the direction opposite to the clockwise movement, turn it over. For a more reliable grip, the edges of the base are bent inward.
Some craftsmen use a simple plastic bottle to remove the base from the cartridge. The neck is heated until it softens, and then screwed into the base. Seconds after 30 start twisting by rotating the bottle
If the attempt fails, the connection must be relaxed by rotating in different directions. When such an action fails, the tool is pushed against the inner walls of the base and unscrewed in this way.
Crafts from incandescent bulbs
Consider the examples of using incandescent bulbs. Many decorators use an old lamp to make a mini-terrarium. Some do-it-yourselfers have learned how to transform a standard lamp into an economical LED lighting device.
The original mini-terrarium of the bulb
First, the light bulb is prepared. After removing the contact, they break the black insulation and pull it out. Using a flat head screwdriver, the internal structure is tipped off, then removed. An empty flask with a socle and an even neat hole remains in the hands.
Next, you can take a beautiful stone or make a twisted stand of wire. In the first case, hot-glue is applied to one of the faces at four points, and a light bulb is glued. Now you can do the design.
As a filler for the terrarium use ordinary forest moss. Add some soil and bark to this. To make it all happen inside, a cone is made of paper and inserted into the hole. At the bottom of the lamp pour drainage of small pebbles, on it - a layer of sand.
All gently level the stick, add soil. After they take the tweezers and place the plants with it. In a syringe with a needle, they draw water and “water” the planted one. Now you need to close the hole. To do this, you can use a hat from an acorn or a cork, cut from a branch.
The terrarium is hermetically closed, but it continues to consume carbon dioxide, oxygen production, the water cycle. It is a kind of small planet with its own climate.
Inside is formed its own microflora. Plants continue to grow and develop.
Some homemade craftsmen based on incandescent bulbs make their own LED lighting fixtures.
To do this, heat the soldering iron and remove the solder at the lowest point of the base. Next, break the insulation, remove the internal filling and maximize the hole.
In parallel, connect three LEDs. To the "plus" of each of them soldered in a resistor. Since the resistance value depends on the power source, its value may be different. Two wires are connected to the circuit for supplying voltage.
Thus, with a little effort, you can modernize an ordinary incandescent lamp, transforming it into an LED. In addition to the satisfaction of a job well done, you will also receive savings.
The design is inserted into the hole, gently straighten to prevent the wires from closing together. Lead the wires through the hole in the base. Connect the lamp to a constant voltage to check its performance. Then the base is sealed.
Safe work with fluorescent lamp
CFLs can be disassembled, but not for further use for crafts, but only if you need to repair the launcher. The flask fluorescent lamp it’s better not to touch it at all, because you need to stay away from poisonous mercury vapors.
The wires coming from the filament lamp to the board, sometimes not soldered to the latter, and twisted on special pins
The structure of such a lamp consists of five parts:
- U-like or spiral flask;
- the upper component of the body with a bulb attached to it;
- electronic board with control gear mounted on it;
- lower case element with electronic ballast;
- base - together with the bottom of the case is a one-piece design.
A flat-head screwdriver with a wide end is used for disassembly and access to the launch controller. With its help, the housing latches are disconnected alternately. To perform an operation, you need to insert a tool into the groove and rotate it.
This is not so easy to do. After long-term operation, accompanied by constant heating, the plastic loses volatile substances, becomes solid. The latches themselves are often broken during the disengagement process.
The lamp opening line is in the place where the technical parameters of the device and the name are applied. The base of the flask is also located here.
If, after all, there was a breakdown of constipation, they are simply cut off with a sharp tool or sawn off. For this you need to arm a small disk cutter. You can buy it or make it yourself.
First, measure the circumference of the hull with a caliper. Then a pin with a cutter is inserted into the chuck of the drilling machine. This is done in such a way that the latter is above the frame at a height equal to ½ the diameter of the lamp body.
The drilling equipment is turned on, the lamp body is pressed against the cutting tool and the external part of the body is carefully notched. Similar cuts are made with an interval of 1.5 cm throughout the contour.
A screwdriver with a thin rod is inserted into the slots and the trimming is raised. After take a screwdriver a size larger and open the housing of the lighting device.
Next, check for serviceability of the lamp flask. Why take a multimeter and check the pairs of conclusions. Normal is the resistance within 15 ohms. If everything is normal, make a conclusion about the fault control module.
If the filament breaks, the ballast may be operational. In this case, the flask is disposed of, and the serviceable device is used as a spare.
If there is a fuse in the control circuit, it may burn out. The question is solved by installing in its place a resistor with a resistance of several ohms.
Burnt items on the electronic board are visible to the naked eye. Based on lamp power, it can be a single or a couple of resistors, transistors or swollen capacitors (+)
If only one filament has burned, it can be bridged by resistance, but this will overload the control gear. Such a restored lamp will not be able to work for a long time - a year at most.
Upon completion of the repair, the two halves of the lamp are simply glued together. To simplify the process of reconstruction, the product is sometimes heated using a building hair dryer.
If the lamp could not be repaired, then it must be disposed of. For information on what to do with used fluorescent lamps, read in this article.
How to disassemble the LED lamp
First of all, it is necessary to check the voltage supply to the contacts of the cartridge. To do this, screw in a working lamp, if the light comes on, the previous device is faulty.
The reasons for the failure of the LED lamp can be very different - the diode has blown or the board is not in order.
Often they stop working due to condensation that has gathered inside the case. In any case, need repair LED-lamp with preliminary disassembly of the structure.
The components of the LED lamp are:
- matrix with LED package;
The bulb is unpressurized because there are no gases in it. The shell can be made of plastic or glass. Plastic diffuser is located at the top.
Applied LED lamp bases varied. The components of the package are groups of LEDs, soldered to PCB or aluminum boards.
Drivers in the form of individual blocks or built into the housing serve to transform the input voltage to a value most suitable for LEDs assembled into groups. The most popular power circuits of the transformer type.
LED lamps are completely safe. They do not emit ultraviolet and infrared rays. There is neither mercury nor heavy metals inside
In order for the interior to become accessible, you need to open the clip clips holding the diffuser dome. If it is attached to the housing with screws, they should be unscrewed.
There is another disassembly method used for devices made with a sizing sealant. To implement the need a syringe with a needle, awl, solvent. In order to detach the diffuser, it is necessary to remove the sealant, by means of which it is attached to the fixing ring.
An awl passes along the edge and inject solvent into the groove with which the syringe is filled. After 30 seconds, the diffuser is removed by scrolling. The radiator is removed with a screwdriver, the LED matrix is unsoldered.
A burnt-out LED is easy to detect visually. He pretends to be a black dot. As an option, to make the lamp work again, a jumper is placed on the edges of the unusable LED, but it is better to change it to a new one.
