When building a house or overhauling, we always have a question about the right lighting.
You can "not bother" to use the sources of lighting, which are traditionally, from year to year, used throughout the former Soviet space, that is, of the type of "Ilyich's bulb".
And you can take advantage of the progress of the industry and purchase modern lighting systems. To give preference to a lamp, you must remember that it is of the highest priority for you and strike a balance between service life, energy consumption, and their appearance.
It should be mentioned that in the case of the choice of lighting lamps, the principle "Economical what is more expensive" works.
The high cost of the lighting lamp is more than offset by the savings in electricity bills. Currently, manufacturers provide us with a huge variety of lamps, so choosing the right one according to the criteria that you have planned for your own home will not be a big problem!
Consider the classification of lamps for home lighting
Each of us from school knows the principle of their work: current is supplied, therefore, the spiral heats up, and, accordingly, gives light.
Recommendations for use:
Such lamps should not be used in those rooms where the light has been on for a long time, as well as in luminaires for stretch ceilings due to strong heat. Such lamps can be used to illuminate a corridor, toilet, bathroom, that is, where there is a need for frequent switching on and off of light with a short time of use.
Such lamps are similar in design an ordinary incandescent lamp. The difference lies in the fact that special types of glass are used for manufacturing and an inert gas or halogen vapor (most often bromine or iodine) is added to the "halogens". D halogen lamps stand out for their long service life, it averages about 2.
5 to 4000 hours of operation. Their power exceeds that of an incandescent lamp, because.the percentage of conversion of electricity into light in such a lamp is 3 times higher.
A distinctive feature of halogen lamps is the presence in the room of the effect of glossy surfaces of illuminated objects.
Recommendations for use:
The modern market presents 3 categories of halogen lamps with narrow, medium and wide angle of dispersion .
The concentration of illumination depends on the size of the angle. This means that the halogen lamp we purchase for reading is not at all suitable for uniformly illuminating an entire room. You can insert such a light bulb into the socket by wearing rubber gloves, or without touching the light bulb itself, but only the packaging.
There are 2 types of halogen lamps: 12 V and 220 V. For the former, an additional transformer is required.
According to experts, 12 V lamps are distinguished by eye-pleasing light, close to daylight, while 220 V lamps emit brighter and less natural light. This category of lamps can be installed in a toilet, bathroom or corridor.
Such lamps are widely used not only in residential premises, but also in offices. We know a fluorescent lamp as a cylindrical hollow tube with electrodes at the edges. Mercury vapor is pumped into such a tube under pressure.
When a discharge of electricity occurs, mercury vapor begins to generate ultraviolet radiation, under the influence of which the phosphor deposited on the inner surface of the tube creates a cold blue light.
The percentage of conversion of electricity into light in such a lamp is 5 times higher than that of an incandescent lamp.
Due to the presence of mercury vapors inside the lamp, disposal of such lamps should be carried out with extreme care: in no case break, do not throw into the trash can. There are special collection points for used fluorescent lamps.
Currently, we offer not only tubular fluorescent lamps for equipping offices, but also lamps designed for standard caps.
Such lamps are called "energy-saving fluorescent lamps".
The most common compact light bulbs resemble a twisting spiral .
Recommendations for use:
energy-saving lamps do not tolerate frequent switching on and off, which is why they are not recommended to be installed in the corridor, bathroom or toilet ...
These are the most economical lamps available today. The efficiency of an LED lamp is 10 times higher than that of an incandescent lamp.
In terms of service life, it is the most durable lamp and undoubtedly the most expensive.
A lamp is constructed from a semiconductor device that generates light when there is a constant electric current. A distinctive feature of the LED lamp is the change of alternating electric current to constant current with the lowest losses for heat generation, which explains the efficiency and safety of such lamps.
When choosing an LED, take into account that there are two main types of bulbs - matte and transparent. Matte type LEDs have more diffused light, and transparent type the brightest, which will be ideal for a crystal chandelier.
When purchasing such a lamp, remember that only high quality LEDs will correspond to the parameters of electricity consumption declared on the packaging. LEDs made in China are of the same efficiency as a fluorescent lamp.
If you have decided for yourself to equip your home with LED bulbs, you need to make the right choice. LED bulbs have a large number of parameters that affect electricity saving, lighting comfort, production cost, etc.
The main ones are:
This is the most significant characteristic for buyers. The economical side of lighting depends on the number of watts consumed.
It is important to know that when replacing incandescent lamps with LED ones, the power of the proposed option must be reduced by 5 times. Ie.if a 75W bulb can be replaced by a 15W LED bulb.
For an apartment and a house, it is necessary to opt for LED lamps with a power of 6 to 8 W, because they illuminate the room better than the "Ilyich lamp" of 60 W.
A few words are worth mentioning about tension. Bulbs operate from 12 and 220 V. The former are used for rooms with high humidity, for example, installing lighting in a bathroom. It would be wrong to buy 12-volt light bulbs counting on the fact that they consume less electricity.
In order to spend time in a room with comfort, you should not give preference to LED lamps with bright daylight, such are often used in industrial premises and offices.
In this case, the preferred range will be from 2700 to 3000 Kelvin , because that this temperature segment demonstrates the yellowish glow of the usual sunlight. The color on the packaging is usually indicated in words. Choose models that are labeled "warm white" or "soft white".
When choosing an LED lamp according to the type of cap, you must choose the option that was before.
For example, when a regular E27 threaded base is screwed into a chandelier, you need to buy an LED with exactly the same thread.
If you decide to install a spotlight, you must choose a lamp with a GU 5 base. 3. The following types of thread are used in bedside lamps and wall lamps: E27 and E14 (Mignon).
The shape of LED lamps is diverse: round, elongated, pear-shaped.
In this case, your choice should be based on your taste and lamp design.
An important thing for LED bulbs is the presence of a heat sink, which removes the temperature from the LED block. If the offered model does not have a cooling system in the form of an aluminum ribbed surface, you should not buy such a bulb.
It happens that manufacturers of inexpensive products put a radiator in the form of a plastic tap. Experts do not recommend buying such products, because plastic has many disadvantages and, in comparison with aluminum, it does not have such a high cooling efficiency.
It is worth remembering that matte bulbs do not allow viewing the presence of a radiator.
When choosing an LED lamp, pay attention to the working life ... At present, the figure can reach 50 thousand hours or more, which corresponds to about 15 years of work.
But don't trust such information.
The reason is that after the time elapses, the LEDs undergo a degradation process, and the quality of their luminescence deteriorates.
When choosing, it is better to start from the warranty period, which is from 3 to 5 years.This means that if the light bulb breaks during this time period, it must be replaced with a new one free of charge.
This parameter must be taken into account when buying LED bulbs for home.
The nature of the lighting will depend on whether the LED lamp is equipped with a diffusing lens and whether it is coated on the inside with phosphors. Look at the location of the LEDs, when they are in the same plane, the lighting will be narrowly directed, and the multi-level placement of the diodes will provide diffused lighting.
An important characteristic is the color rendering coefficient, which is little paid attention to. For good bright lighting, this indicator should be at least 80. A high value is considered to be 95, but the price for such a model will be much more expensive.
Indicate the color rendition on the product packaging.
Packaging will tell a lot about the quality of products, which indicates the following parameters:
If, looking at the packaging, you did not find most of the parameters with your eyes, you should doubt the quality of such products.
When giving preference to one or another LED lamp, you should pay attention to the product itself: all fastening elements must be made without irregularities, gaps and roughness.
Company - manufacturer - information is quite important to the consumer.
The quality of the products we purchase depends on the manufacturer. I would like to say that both foreign and domestic companies produce highly reliable products.
Advantages of LED lamps :
Recommendations for selection and operation.
LED lamps are a real breakthrough in the development of the lighting system, they are more and more popular when choosing home lighting devices.
Be sure to pay attention to the wattage of such a lamp. When replacing incandescent lamps with LED lamps, you can use a simple but effective way of dividing the power by 8. This means that the "Ilyich bulb" with a power of 60 W will be replaced by a LED with a power of 7.5 W.
The presence of ripple or flickering will tell about the poor quality of the rectifier in the lamp power supply. The light emitted by such a lamp can cause visual impairment.
An LED lamp with a built-in motion sensor and night mode will become a very necessary purchase for the home. In the dark, the lamp automatically turns on the standby light, and when a person appears, it turns on full brightness.
This option will be ideal for lighting a technical room, as well as a corridor or a bathroom.
At the end of the article, I would like to say a few words about a quartz lamp. Such an acquisition will become a reliable assistant for parents in the season of the spread of infectious diseases. Its purpose is to stop the infection. Such a lamp is capable of treating skin diseases, as well as joints, diseases of the nervous and respiratory systems.
The choice of such lamps is huge. They differ in technical characteristics and range of procedures.
