Necessary Qualities That a Good Lighting Device Must Have
The electrical and mechanical qualities of the devices are determining effects in very imporant issues such as efficiency, user friendliness, easy installation easiness, environmental and human health concern, besides the product quality.
|
A device which does not have necessary mechanical ability is not able to meet the practicality in assembly and in usage and even the efficiency expectations, and does not fulfill its duty as necessary.
A product which is not electrically secure and does not meet the mentioned requirements in the related quality standards, might cause serious damage to environment and human health. The products that are not grounded continuously according to IEC EN 60598 standard, and that lack the additional security precautions(double isolation or supported isolation) create risks for human life.
The main features of the high quality device which is in compliance with international quality standards, has easy installation and usage, which can fully meet the electrical and mechanical requirements are as follows;
Resistance Against Rust and Corrosion:
The metal parts of the devices must be sufficiently protected against oxidation because the rusting of those parts might cause the luminaire to become insecure.
The metal sheet parts of the device must be pre-processed conveniently and their surfaces must be smooth, they must be painted with electrostatic powder coating which is durable against heat, humidity and UV, has sufficient resistane against being scratched and stain. These properties are determinative for the resistance of the device against rust and corrosion.
It is necessary that the devices used on the exterior of the building and the ones that are used in the humid zones inside the building must be produced from materials which are sufficiently durable against corrosion (stainless steel, aluminium, copper, bronze, brass with no less copper ratio than 80%, polimeric materials,.); that it must be considered if the paint property and paint thickness is convenient to the respective humidity and other conditions. |

Ballasts and Energy Efficiency:
C.E.L.M.A.* , has determined that the biggest energy loss is at the ballasts according to the studies they held in lighting systems. Afterwords, an energy efficiency classing named Energy Efficiency Index (EEI) was created. According to this classing that was created in order to reduce the energy losses and to provide energy saving; D and C classes magnetic ballasts has high loss, B1 and B2 class magnetic ballasts has low loss. Electrical ballasts are the lowest loss ballast class.
In our country, since June 2006 it has been forbidden to use D and C class magnetic ballasts.
For these reasons, while making device choices, B1and B2 class magnetic ballasts or electronic ballasts must be preferred.
C.E.L.M.A. is a commitee that consists of national components producers unions in European Union.
Grounding and Isolation:
The components used in the products (light socket, cable, connector, ballast, lamp, ignition,..etc.) must be chosen in compliance with international standards. In the products, grounding must be provided according to the IEC EN 60598-1 standard or additional security precautions (double isolation or reinforced isolation) must be applied.
Grounding: All the metal parts inside the device and on the visible surfaces must be in touch with each other and with the network.
Protection Degrees (IP xx Values)
IP xx values show the protection degrees against water and solid objects coming from outside. While making the choice of the lighting device, it is important to select the device with IP degree which is convenient to the conditions in that specific environment. The device which is especially used on the exterior of the building or inside the building but in humid places must be on an IP xx value that can stand enviroment conditions. (For the table showing the IP values, see page 27)
Temperature Increase - Lamp / Device Life:
The electrical and electronic components inside the device produce heat while the device is working. When this temperature becomes higher than the working temperature value declared by the electrical and electronical component producers, the life of all the equipments being used (lamp, ballast, cable, light socket etc.) is shortened.
According to Newton cooling law (Q = m.c.?t); every 10?C temperature increase above the declared working temperature causes every time approximately 10-15 % decrease in the life of all the equipments being used (including the lamp).
Briefly;

The devices that are not in compliance with international norms and standards, do not pass the necessary temperature tests and that have the above mentioned disadvantages; cause high maintenance costs and short-life products. Therefore, while choosing the devices, it is important to check whether necessary temperature tests are held or not.
Reflector and Light Efficiency:
Electronic ballasts provide necessary operating parameters for fluorescent lamps by drawing less energy when compared with conventional ballasts. Energy drawn from network is the total amount of energy transmitted to the lamp and the lost energy. Electronic ballasts operation in high frequency enables lamp to draw less energy from network for
Therefore, on the reflector of a good quality device the aluminium purity has to be above the necessary level, the reflectors with polished aluminium must be preferred.
Electronic Ballast - Magnetic Ballast Comparison :
Energy Saving : Electronic ballasts provide necessary operating parameters for fluorescent lamps by drawing less energy when compared with conventional ballasts. Energy drawn from network is the total amount of energy transmitted to the lamp and the lost energy. Electronic ballasts operation in high frequency enables lamp to draw less energy from networ for providing the same light beam. Furthermore, electronic structure of ballast keeps power losses low.
Long Lamp Life : Lamp life is practically related with turn on-off count rather than its catalogue value. As turn on-off count increases, a decrease in light beam provided by lamp is seen; lamp's life shortens also in this proportion. Electronic ballast turns on the lamp without overforcing (pre-heating flament before transmitting any controlled current) electronic ballast at the beginning, causes minimum quantity of particles loss on flament. Therefore life of lamp operated by electronic balast is longer in %20-%50 proportion than that of lamp which is exposed to uncontrolled currents. This saving is especially important for expensive lamps. If we consider that during life of electronic ballast, lamp is replaced 5-10 times, electronic ballast will save many times its first investment cost.
Proper Ignition : Fluorescent lamps, operated by electronic ballast, turn on without any flickering when switch is turned to on position. Ignition problems seen in use of conventional ballast are not met. Ignition time which is 2,8 sec. for conventional ballast is approximately between 0,4-1 sec. for electronic ballasts.
High Power Factor : Power factor which is at 0.5-0.6 levels in conventional ballasts, is above 0.95 in electronic ballasts with filter circuit. Since electronic ballasts do not draw reactif power from network, there is no need for compensation capacitor.
With all these features, electronic ballasts are %35 more efficient than conventional ballasts and, during their operational life with consumption difference electronic balasts do not only amortize their first investment cost in a short time, but they generate also saving for long years.
Most of Lamp 83 Products have versions with electronic ballast. Your sales representative, in case of your inquiry, will give further information about products with electronic ballast or present an offer to you.

Material Quality:
. Screws and mechanical connections must have the strength to stand against the mechanical forcings that might be caused during usage.
. The device must have been designed and produced in order that it is not in touch with the high tension parts which are created during the assembly and replacement of the lamp or starters (starter, ignition etc.).
. The mechanical, electrical and thermic endurance of the isolated coatings, sleevings and similar parts must be sufficient.
. The security factors of the mechanical hanger elements must be sufficient. The parts where the conductors pass through must be smooth and clear from sharp edges and any casting burrs during the cable isolation phase. The parts such as metal adjustment screws should not cause excess towards the areas where the cables pass by.
. The glasses used in the products must be of tempered glass. The glasses that are not durable against heat might break due to incerasing temperature of the device and the ambient and this might cause undesired accidents and results.
. They are safely used in areas where fire inspection is very important, due to the silicone isolation on the cables, high heat resistance and fire retardancy features. Silicone's high heat conductivity, (low specific heat coefficient: 15,9 Mj/kg) provides that the cable's continuous working temperature stays at low levels. Due to this characteristic, Silicone cables carry 50 % more current when compared to PVC or other polymer based cables. For these reasons, the cables used in a high quality device must be silicone isolated cables.
. The devices must have been designed so that they allow easy installation and their mechanical advantages must provide easy installation. Together with the device, necessary mounting drawings and instructions must appear either on the user's manual or seperately.
. Instructions and regulations that are towards protecting the environmental and human health, absolutely prohibits certain materials to be used. Mercury is one of the forbidden materials to be used in the production and in the product. Besides, polimer metarials which are used inside and outside of the luminaire should not diffuse halogen gases when burned.
It is necessary that the materials which will cause damage to the environmental and human health are not being used both at the production process and in the device itself
