How does the G4 galogenki
Device halogen type with G4 cap has a specific structure. Inside there is a filament member and a buffer gas, or rather, a pair of halogens iodine or bromine.
Filling such a plan increases the temperature of the inner coil core and increases the life of the lamp element.
Total working temperature helix halogen lamp socket while G4 is about 3000K, and the light output level ranges from 15 to 22 lm / W.
Deciphering lamps marking
The letters are used to indicate the type of the primary lamp cap. The letter G is marked pin base and the numerical value indicates the distance between the working contacts in this case amounts to 4 millimeters.
The length of the pins themselves, by means of which the module receives electric power necessary for operation, does not exceed 0.75 mm, and the diameter can not be less than 0.65 mm.
G4 Cap type is ceramic, metal and plastic. The first two types are considered more reliable, easy to withstand high temperatures and are not afraid of intense operational loads.
When installed in the lamp, plug-in lamps galogenki not screwed and vschelkivayut in the lighting fixture. The pins are included in the structure tightly and securely hold the lamp in the workplace.
Socles with GY4 coded GU4 are further modification of the classical variant G4 and have small variations in the base diameter metal pins or the distance between them.
The operating principle of G4 products
Inside G4 galogenki located tungsten spiral. When the device is connected to an electrical current passes through contacts, is supplied to an incandescent element and heats it to a high temperature. At this point, the glow is formed in the lamp.
The high operating temperature causes the tungsten atoms evaporated from the helix. Located in the flask and the surrounding halogen incandescent body pairs are connected with tungsten atoms and prevents their condensation on the cooler inner surfaces of the flask.
The entire process relates to a reversible and is a kind of cycle. On the substance constituting the working compound decomposes in the vicinity of the filament helix at the expense of high temperature and tungsten atoms are returned again to the same place where they were.
This makes it possible to significantly increase the operating temperature of the scroll portion and to obtain a much more vivid, intense and homogeneous light stream.
Contacting only with a spiral element, tungsten atoms are not adversely impact on the interior surfaces of the bulb itself and the service life of the light source is greatly increased.
The same time helps to reduce the size of the bulb, while retaining its capacity in full.
General characteristics of devices
Halogen with G4 socket products consume significantly less power than the classic incandescent lamps.
Their service life is in the range 2000-4000 hours at normal operation in optimal conditions specified by the manufacturer in the accompanying documents.
Tungsten filament located within the bulb in operation during warming up to 3000 ° C. Light output, depending on the typical construction of the module, is from 200 to 5000 lm. Nominal voltage may have different parameters, depending on the application of the light source.
Scope of light sources
Thanks to the efficiency and small dimensions, G4 bulb with a capacity of 5-10 watts are ideal for decorating and decorative accent lighting in rooms for different purposes.
These devices often use designers to create in the room bright light spots, lighting zones or effect of a starry sky. High power products are mounted in fixtures for arranging the background lighting.
Classification modules G4 cap
This type galogenok produced in two ways: in the form of a small capsule size or frustoconical reflector. Each of the designs intended for a particular purpose and suitable conditions correctly provide the required light output.
Features capsular devices
G4 galogenki having elongated elongate flask of quartz glass, called capsular or penlight. Spiral filament therein is located longitudinally or transversely, and usually in a single layer.
The rear wall of the inner space covered with a reflective formulation. The additional external reflectors and protective elements of the modules do not need.
product compactness makes them suitable for illumination of furniture, ceiling spaces, storefronts and shopping facilities. In everyday life, small light sources complement decorative sconces, chandeliers and lamps unexpected shapes and configurations.
Being a low-voltage light sources, for the correct connection to the network 220 W needed in a transformer, down-base voltage.
Capsule type devices generally have a range of warm working light stream. However, in comparison with classical incandescent lamps, they range in tone is much closer to the natural white luminescence, characteristic of the natural environment.
G4 galogenki even at low power and have a good brightness with little or no distortion transmit complexion people staying in the room, and the interior elements and furniture illuminate pleasant neutral warm light.
On the illuminated surface capsular devices provide an attractive gloss effect, while maintaining a natural tone, originally peculiar subjects.
This option allows you to transfer the total light color interior orientation, highlighting its most eye-catching and original elements.
Distinctive features of models with reflector
Halogen G4 device with a reflector have a specific shape resembling a truncated cone, and are called reflex. They serve directed light stream at different angles.
Inside the bulb such devices there is a special element that reflects light and distributes it more clearly and evenly.
The reflector is usually of two types:
The first type is a translucent texture and actively exhausts heat back, which significantly strengthens the base intensity of the light, but makes it flow diffused and wide.
The second option redirects the generated heat on and creates a narrow, bright and concentrated light beam.
The design of the light bulbs are also some differences. Different manufacturers produce modules with G4 socket like a protective glass cover, and without it. Product Configuration is determined by special-purpose designation.
Angle of dispersion reflecting G4 halogen type lamps is in the range from 8 to 60 degrees. This quality makes it possible to mount the light sources with reflectors in the instruments that allow spotlighting products and exhibits.
Modules having the outer damage protection, suitable for use in open luminaires any configuration. Galogenki without cover are mounted only in enclosed fixtures, where the surface of the bulb is no direct access.
Advantages and disadvantages of light bulbs
As with any other devices intended to create a modern, practical and comfortable lighting systems household, decorative and other purposes, a halogen type light bulbs equipped with G4 cap have certain advantages and limitations.
The first category includes parameters such as:
- more economical consumption of electric energy compared with conventional incandescent lamps;
- optimal brightness light stream, there is greater concentration, but does not result in eye strain in both adults and children;
- good light density and the almost complete absence of distortion of the natural colors human faces, furniture, interior design and decorative elements in the illuminated room;
- almost 100% lumen transmitted lamp, throughout the operating period, declared by the manufacturer;
- 30% more light at equal supplied with lamp "Edison" power;
- compact, by which the product can be used in outdoor and indoor lighting devices of different sizes, intended for the organization of a point, zone or background lighting;
- increased strength of the outer quartz bulb;
- prolonged service life - from 2000 hours in compliance with the basic rules of operation and up to 12 000 hours in the organization in soft-start system;
- presence in this segment of the large number of proposals from established, reputable brands, well-proven in the market of lighting equipment and related items.
All these criteria are attracting the attention of customers and offer them at purchase give preference to halogen units.
But, despite the large number of positive qualities and advanced features, such as halogen products have also have their negative traits. They are somewhat less than positive, but do not take them into account in the organization of the lighting system is simply unreasonable.
Among the disadvantages are mentioned most frequently are as follows:
- not too high level of efficiency is only 50-80%; such indicators are due to the expenditure of large amounts of energy for heating of the base product;
- insufficient strength of the device casing, vulnerable to mechanical damage;
- health hazard - in the case of violation of the integrity of the structure of the flask gas escapes into the atmosphere, has a negative impact on the person and provoke migraines and severe headaches;
- High vlagovospriimchivost - limits the scope of use galogenok and makes it impossible to use them in the bathroom because of the frequent changes in temperature and the presence of constant condensation.
Modules, spent his time, throw in a regular trash can is undesirable. Pitched, they emit harmful to humans and the atmosphere pair.
They are recommended to send in special containers for recycling chemical waste or to take the company in charge of the disposal of equipment containing corrosive substances.
Of course, all these points are not fatal and not worth it to completely abandon the operation galogenok. Just before the purchase is well worth to consider all the pros and cons in order to understand how to use the positive qualities G4 lamps, and the impact of negative reduced to a minimum.
