To replace a burned-out light bulb in a lamp, you need to understand the types of devices and select the failed element correctly. It is important to understand how the light source is structurally designed so as not to break it, not to damage the decoration of the room. Before going to the store you need to determine the type of product, the type of cap, power. Having complete information, you can easily change the LED bulb in a spotlight yourself.
Types of Used Bulbs
Point light sources are used as the main and as auxiliary devices to focus on individual elements of the interior. A characteristic feature is the limited emission angle. The light is directed. This makes it possible to apply special design techniques, combining the number and characteristics of lamps so that the house takes on an original look.
Products with a traditional filament are a thing of the past. Production is limited, in the coming years their market share will be measured by several percent. The most popular are LED and halogen lamps.
Unlike the old-style lamp, where a vacuum is created in the bulb, in modern products there are additional substances that improve the quality of the device, its efficiency. If iodine or bromine are used in the production, the models are called halogen. Fundamentally, they do not differ from traditional products.
Fluorescent lamps are a gas discharge device where a phosphor starts to glow in live mercury vapor. The LED is a semiconductor element with high efficiency and low operating temperature.
Comparing halogen and LED lamps for a combination of characteristics, several features can be noted. Halogen models require high temperatures up to 500 ° C for optimal aperture, LED analogs have a value of 60-100 ° C. Many experts believe that halogen is more pleasing to the eye, similar to daylight and gives high quality lighting.
Halogen is 2 times cheaper, but it also has a shorter service life. LED lamps for economic indicators are more profitable.
Types and methods of fastening
Before changing LED lamps, you need to find out the features of their mounting. Products in this category are divided into the following three types:
- recessed;
- waybills;
- outboard.
For recessed lamps, space is needed, so they are installed on frame bases, for example, in a suspended ceiling made of drywall, plastic, panels. Overhead options can be fixed on any suitable surface.
Regardless of the mounting design, the fixtures can be swivel and stationary. As fasteners, spring brackets, screws, screws, bolts, less often nails, are used. Luminaires for 220 W and with a transformer for 12 W are offered. If a room with high humidity, such as a bathroom, is equipped, it is better to choose less power for safety.
When mounting on drywall, do not use the hardware provided. You need to purchase special items, such as a butterfly.
Light Source Replacement Steps
Before replacing spotlights, turn off the light. Before going to the store, you must remove the old lamp and see its design. Sometimes problems arise with built-in models, with MR16 lamps, which use hidden fixation. It can be a spring clip or a threaded ring.You need to look in the product passport on how to open the ceiling lights to replace the lamp if no obvious fixing elements are visible. In these products, the most commonly used pin base is GU4, GU5,3, GU10. Two pins are inserted like openings into holes.
The same principle of fixation for lamps G9 and G4, where the number indicates the distance between the pins. Two types of lamps are used: halogen and LED. They differ from the GU series in the shape of the bulb - it is finger-shaped, not conical.
Another growing standard is denoted by the abbreviation GX53. This is also a pin base of reduced thickness (1.5 cm). You need to work with them the same way as when replacing the LED bulb of other standards. Often such lamps are called tablets. An advantage is that it is possible to significantly reduce the inter-ceiling space, which is important when installing tension and drywall structures.
With screw lamps there are no problems. The element is twisted counterclockwise, twisted in the opposite direction. The most popular models are E27 (large base 27 mm), E14 (small base 14 mm).
The bayonet mount system is almost never used. Finding a lamp and a base with a swivel mechanism is problematic, it is easier to notice the whole cartridge.
Replacing bulbs as follows:
- The power supply is turned off.
- The lock is removed, a protective transparent case.
- The lamp is unscrewed or removed.
- If necessary, recessed fixtures are removed from the base.
- The name, type, power is checked and checked in the lamp passport with recommended and maximum power values.
- A new one with the same characteristics as a burnt one is screwed in.
- The lamp is going.
After the installation is complete, electricity can be supplied.
Special attention deserves the operation to replace the fixtures, if the ceiling is stretch. Under the lamp, a reinforcing ring is mounted on the canvas first, which protects the base from tearing. It is impossible to dismantle it.
Plasterboard ceiling is not made with reinforcing elements. Difficulties can be caused by the complicated design of the LED chandelier. You can find out how to change the lamps in it in the instructions for the product.
Halogen bulb bulbs must not be touched. Installation is recommended with gloves on.
Security measures
In work, first of all, it is necessary to take care of health. All work is carried out with electricity completely disconnected.
Energy-saving fluorescent lamps must be protected from destruction. They contain mercury. For this reason, lamps must not be disposed of with household waste. It is necessary to take them to the collection point.
If you need to increase the cable, you need to use connectors or reliably wrap the twist with insulating tape. Adhesive tape, adhesive tape can not be used.
When working with suspended ceilings, special care should be taken. To insert an LED lamp into the ceiling lamp on such a basis and not damage the coating can be difficult. Accidental contact with a sharp object can lead to complete loss of the web.
If the lamps are installed in a suspended ceiling, a niche, furniture, for this purpose only LED lamps are used. Operating temperature in the region of 70 ° C will not damage wood, chipboard, LMDF.
