Of all modern light sources, halogen lamps have the highest quality color rendering. In addition, halogen lamps are characterized by high brightness and directional radiation. Of course, they can only conditionally be called energy-saving, nevertheless, in comparison with incandescent lamps, they have several times greater light output and doubled service life.

There are so many different halogen lamps. In this article we will get acquainted with their main types and features. All halogen lamps are conventionally divided into two large groups: low voltage (low voltage) lamps - up to 24 V and mains lamps - 220 V. In addition, halogen lamps differ in design and purpose. Linear halogen lamps. The lamps are a quartz tube with leads on both sides ...

Properly designed lighting can dramatically change and transform street space at night. At the same time, the presence of lighting in the yard in the country or in a country house is necessary not only for beauty, but also to ensure safety, and also, to some extent, such lighting serves as a home guard. In this article, we will figure out what kind of street lights there are for a summer house and a country house, how to choose the right one and what is the best way to use it.

Today on sale there is a huge number of lamps to illuminate the yard and garden in the country or in a country house. It is very important not to get confused when choosing street lights, since the final look of your site at night, the possibility of practical implementation of everything you plan, the final cost of the entire street lighting system, as well as the further operation of this entire farm, depend on what is chosen.

I must say right away that I am not professionally engaged in lighting design and I am not a specialist in this field. I was always more interested in technical issues in the lighting of rooms (lighting engineering, various light sources, automation and lighting control). Although I really like beautiful interiors and can spend hours watching thick glossy magazines on interior design, construction and repair with bright color pictures. I especially like magazines with photo examples of real projects. My favorite magazines of this type are Major House and Beautiful Apartments.

Flipping through this type of magazine, first of all, I pay attention to how the coverage is organized in a particular case. At the same time, somehow imperceptibly for yourself, you begin to notice and clearly realize the general trends in the development of home lighting: what lamps and fixtures are used, how they are placed, how the illuminated interior looks from different angles, and much more ...

Good coverage books are very rare. I already have a dozen books on this subject on my bookshelf, but only a few books are worthy of attention. One of the books on lighting that I found very useful is Lucy Martin's book, The Effects of Home Lighting.

This year I started a major overhaul in my apartment. Repair is very large-scale and complicated. When planning the repair, I provided for the replacement and modernization of not only all engineering networks, but also a complete alteration of the lighting system. Moreover, I borrowed interesting lighting ideas for each room in the apartment from the book "Effects of Home Lighting".

The book was bought by me in an online store shortly before the repair and fully met my expectations. In fact, this is an encyclopedia for organizing home lighting. Released by publisherstvom "Art spring".The book is translated from English. The author of the book is Lucy Martin. She is a lighting designer by profession ...

Recently, very many began to face the problem of frequent burnout of incandescent lamps in their apartments. Incandescent lamps should last one thousand hours, but in reality they burn out much faster. And if ten years ago it was possible to put up with this bad phenomenon, since the lamps cost a penny, now it is already becoming a real problem. Prices for incandescent lamps are rising, and their life, alas, is constantly decreasing.

ABOUTThe main reasons for the rapid failure of incandescent lamps. Poor quality lamps. The quality of incandescent lamps of domestic production leaves much to be desired. For some reason, the most powerful small lamps burn out (up to 60W), just the ones that are most often used in lighting in everyday life). All domestic plants are approximately the same in quality. Of all domestic enterprises, the highest quality is considered ...

Around compact luminescent, so-called. energy-saving lamps in recent years there have been many rumors and myths. In this article, we will try to dispel some of the most common myths.

The first myth. Energy-saving lamps emit UV rays that are harmful to health.

It is known that light has on the human body affects the metabolism in the body, physical development and human health. The most useful in this regard is daylight (light from the sun). In artificial lighting when using incandescent lamps (thermal light sources), ultraviolet radiation is completely absent.

Ultraviolet radiation in the volume that we receive from energy-saving lamps is not only not harmful, but even very useful for the human body. It relieves fatigue, eliminates depression ...

Given the high popularity of LED light sources both among buyers and sellers, you should dwell in more detail on what parameters are used to characterize the consumer properties of such lamps, which, in fact, should be paid attention to when buying.

First of all, any lamp, including LED, is characterized by the amount of power consumption (watts). Typically, the power of LED lamps for domestic purposes ranges from 1 to 10 watts, although there are much more powerful sources for street lighting - 100 watts or more. Strictly speaking, the power consumption characterizes only the rate of energy consumption from the network, and in order to understand how much the lamp shines, you should ask the seller about the amount of light output. The luminous flux is measured in lumens and most fully characterizes the light source ...

As an example of calculating the illumination, we consider the use of luminaires built into a suspended ceiling. This case, on the one hand, is quite relevant, on the other hand, it is practically not described in classical manuals on lighting engineering and, finally, quite complete data on the characteristics of halogen lamps with a reflector are given in the catalogs of light sources.

The OSRAM catalogs provide not only parameters such as axial luminous intensity and a flat angle corresponding to the solid angle, within which the luminous intensity drops by half, but also a curve of the angular distribution of luminous intensity, as well as a visual image of the change in illumination as the distance from the lamp changes. Consider first the task of lighting a bathroom measuring 1.7 x 1.7 m2.We ask ourselves: what is the minimum number of halogen lamps that must be used to meet the requirements ...
