How to change a light bulb in a false ceiling
Even ordinary everyday questions can be puzzling no worse than a rebus , for example, how to unscrew a light bulb from a false ceiling, especially if the lamp differs from the standard pear-shaped one, and the ceiling structure is not intended for regular dismantling. With the advent of new luminaires, the problem of replacing light sources has become more sophisticated.
Selection of a type of light source for a false ceiling usually occurs on the recommendation of furniture assemblers, sales consultants or builders. Naturally, few of the various advisers, when proposing certain options for lamps, thought about how to replace a lamp in a suspended ceiling. Most modern luminaires are not ergonomic.
If ebonite bulky cartridges for simple incandescent lamps in USSR chandeliers, as well as floor lamps, made it possible to replace even small children, but in modern technology, before unscrewing a light bulb from a suspended ceiling, you need to familiarize yourself in advance with the device of the lamp and the method of its attachment to the suspension. At the first attempt, usually before pulling out a light bulb from a suspended type of ceiling, it is required to unscrew or unbend the mount and pull out the body fully.
In modern lighting devices, lamps of several varieties are used:
- Halogen, with a conventional spring-loaded connector or a miniature E10-E14 base.
- Fiber-optic lamps, in fact, are the same halogens or light diodes with an additional light flow deflector.
- LED lamps with a miniature base, but structures equipped with a spring-loaded contact can be used in suspended ceilings.
- Economy lamps are fluorescent type and are the most difficult to replace. Before replacing a fluorescent lamp in a pendant type ceiling, additional safety measures are imperative.
- A classic incandescent lamp with a small glass bulb and a conventional E10 screw base. It is easiest to unscrew this lamp from the socket if its body is made of ceramic and has a full thread.
Please note that 80% of the problems with the failure of light bulbs are connected precisely with the terrible contact on the base.
In some cases, it is simply unrealistic to unscrew a light bulb from a burnt-out cartridge without disassembling it.
Even the highest quality and most durable LED array quickly begins to overheat and breaks down much earlier than the warranty period expires. Especially if the luminaire is mounted on false ceilings in a kitchen or bathroom. For such premises, it is recommended to use devices with clamping contacts, you do not need to figure out how to unscrew, and even get a tungsten lamp from a suspended ceiling after the cartridge is strongly attached to the screw-type base.
Good advice! In some cases, it is useful to unscrew the mount or lamp and check to what extent it has warmed up (base and contact part).
If the lamp began to overheat, then you need to check the clamps on the contacts or unscrew the lamp from the socket and replace it with a less powerful one.
The reality is that bathrooms, kitchens and living rooms are increasingly using efficient and more economical LED, halogen or fluorescent bulbs. They are usually selected in order to complete point or linear lighting devices. In any case, they all burn out, and therefore almost all owners of modern interior designs will need to face the problem of how to change a light bulb in a suspended ceiling.
Contact and cartridge options.
Modern light sources are connected to electrical wiring, which is hidden behind a suspended ceiling, using several methods:
The easiest way is with screw-type cartridges, it is enough to remove the retainer and twist the flask, it will work even with one hand. If the lamp is mounted in a socket with a center spring-loaded contact, then before removing the point-type luminaire from the suspended ceiling, you need to turn or move and twist the lamp bulb without removing it from the holder.
Often, in such lamps, the side-type contact simply leaves or begins to oxidize. In two-pin LED, or much more often halogen lamps, the contacts are fixed with screws. It is safer and you do not need to try to unscrew the lamp from the socket. But if it burns out, you will need to disassemble half of the lamp pendant to replace it.
For plastic and PVC false ceilings, lamps with reduced power, maximum 35 watts, are used.
Usually these are compact two-pin cans with a matrix of light diodes, with dozens of emitters, sealed inside a glass bulb. After turning on the contacts from the power supply, the lighting device will be inserted into the reflector and attached to the lighting device case. Before replacing the LED lamp in the false ceiling, it is necessary to remove the wire ring spring, release and pull out the reflective housing. The whole structure will be hanging on the wire. To release the lamp, you need to unscrew a couple of screws on the contact blocks, insert a new bulb, screw the mount and put the entire assembly back in place.
All that remains is to mount the decorative rim and spring.
Good advice! Before starting work, it is advisable to put all the necessary tools, including the lamp, in a belt bag or pocket in advance.
With one hand you can hold the wiring, and with the other you can unscrew the contacts without dropping the old bulb. It is very inconvenient to run after a spare lamp or tools, for which electricians do not like to twist and replace two-pin lamps. For simple wall lamps and chandeliers, LED lamps with an E27 screw base are used.
In this case, the replacement will look noticeably better.
The lampholder itself with wiring is attached to the luminaire body and is firmly held by means of a false ceiling panel. To turn out the pear-shaped flask made of matte polycarbonate, it is enough to remove the cover on the clips and get the burned out device. It is often not enough just to unscrew the LED lamp, its operational life is quite long, from 10,000 to 30,000 hours. For this reason, after opening the luminaire body, it is recommended to check the condition of the contacts, the operation of the regulators and the dimmer, and only then mount the parts on the suspended ceiling.
One of the best home lighting designs is the halogen lamp. If you ask experts in the ergonomics and design of household lighting, you will definitely hear a lot of flattering reviews:
A halogen lamp in design and arrangement strongly resembles a standard bulb-bulb with a screw-type base.
For suspended panels, modifications with a miniature E14 base are used. Unlike other types, halogens do not have a diffuser for diffusion, and therefore you can unscrew it from the cartridge in a couple of movements. The only limitation will be compliance with the complete cleanliness of the glass flask.
Before removing the light bulb from the false ceiling, the glass on the new part must be wiped with a cloth that has been moistened with alcohol. In some cases, it is required to unscrew the old halogen with cracks on the working surface.
In the most difficult case, it will not be possible to unscrew a burnt halogen "pear" from the cartridge even by means of a loop. In this case, the damage is sealed with double-sided tape, and only then can the device be removed from the cartridge. Knowing the technology for replacing halogens, it will be possible to easily figure out how to replace a fiber optic lamp on suspended ceilings.The diffuser reduces the heat load on the glass surface, and therefore the bulb can be handled in the same way as with a simple lamp.
One of the most unpleasant cases is the one associated with replacing a burst or broken lamp.
If a flask made of cracked glass looks intact, this does not mean that it is not capable of collapsing in the hands of even the slightest attempt to remove it from the cartridges. For this reason, all manipulations with cracked glass must be carried out with cotton gloves and de-energized. To be able to unscrew the halogen lamp, its flask needs to be pasted over with several pieces of tape. The glass of halogen-type cylinders is thick enough, and it is required to stick it only in order to avoid leakage of gases and the appearance of sharp chips along the crack lines. The most difficult case with fluorescent lamps, and before unscrewing the cracked housekeeper and its flask, you need to put on a bag, and the effort should only be applied to the base of the plastic lamp.
And in the worst case, if the flask shattered into pieces, and the base remained in the cartridge, then there is only one option left - to release the ceiling panel with the analysis of the plastic socket.
In certain models of luminaires, Chinese non-separable ceramic holders are used. In this case, you can unscrew the light bulb from the suspended structures with simple pliers of the locksmith type. If the contacts are burned out, and badly, then it will not be difficult to get the case even with one hand.
