Surface-mounted industrial and specialized
Lighting used in industrial conditions must be characterized by a high level of resistance not only to various harmful conditions, but also to mechanical damage. That is why surface-mounted, industrial and specialist lamps are distinguished by, among others, high IP coefficient and tightness class. Broadly understood industrial lighting is used in such facilities as: - production halls, - sports halls, - laboratories, - schools, - warehouses, - workshops, - factories, - underground garages or parking lots. How to choose surface-mounted, industrial and specialist lamps When choosing specialized lighting, you should pay attention to, among others: on the following parameters: - IP tightness class (from International Protection Rating, sometimes Ingress Protection Rating) - this is the degree of protection provided by the housing of the electrical device. For the value of the index, protection against access to live or moving parts inside the enclosure, protection against the ingress of solid objects and against the harmful effects of the ingress of water or other liquids are important. The designation consists of the letters IP and two numbers (and two optional letters - additional and supplementary). The first digit means that the enclosure provides protection for humans against access to dangerous parts located inside and at the same time provides protection against penetration of foreign solids. 0 means no protection in this case, 1 - protection against access to hazardous parts with the back of the hand, as well as against solid foreign bodies with a diameter of at least 50 mm. The highest grade - 6 - means protection against access to hazardous parts with wire and dustproof protection. The second number indicates to what extent the housing provides protection against the effects of water ingress. In this case, again, 0 means no protection, while 1 - protection against falling drops of water, and the highest level - 8 - protection against the effects of continuous immersion in water. According to the DIN 40050 standard, level 9 can also be distinguished, which means protection against flooding with a strong jet of water under pressure (80-100 bar and +80°C). Example 1: a lamp with the IP54 marking is characterized by protection against foreign solid objects with a diameter of 1 mm and more and protection against water jets (12.5 l/min) poured on the housing from any side. It is therefore a device completely resistant to water and dust, which means that such a lamp will also work in production halls or car workshops. Example 2: A lamp with an IP20 marking is characterized by protection against foreign solid objects with a diameter of 12.5 mm and larger and no protection against water and moisture. Thus, it will be suitable outdoors (insects will not get into the enclosure), but it should be mounted under a canopy so that it is not exposed to rain. - strength class IK determines the degree of protection against impact. The marking consists of the letters IK and two numbers - on an 11-point scale (from "00" to "10"). The higher the value of the IK parameter, the better the level of mechanical strength. In the case of workshops where mechanical damage to the lamp is possible, it is recommended to use luminaires with IK08 resistance. Example 1: Classification level 01 corresponds to a 0.15 joule impact, equivalent to a light hammer blow. Example 2: Classification level 10 means 20 joules of impact, equivalent to being hit with a 5 kg hammer from a height of 40 cm. - shock protection class - marked with levels 0 (the device has only basic protection, provided by basic insulation) I, II, III (the highest level means protection against electric shock provided by supply voltage not exceeding the permissible safe touch voltage). The most popular types of surface-mounted, industrial and specialist lamps are: - hermetic luminaires - such an element is characterized by a high IP65 tightness class, which means complete protection against dust and direct water jets. The hermetic luminaires available in the el12 offer are additionally characterized by very high mechanical strength of the housing, in the IK08 class. Thanks to this, mechanical damage to the luminaire under normal use conditions (e.g. accidental impact, knocking) is unlikely. In addition, the 1st class of anti-shock protection provides basic protection against indirect contact, significantly increasing the level of lamp use. High-quality plastics from which the luminaires are made guarantee very high resistance to external factors, thanks to which the devices are a product perfectly adapted to use in conditions characterized by high humidity. Hermetic luminaires available in the el.12 offer, thanks to wide-stream distribution and direct light emission, also guarantee a high standard of lighting. Models that use the EVG electronic ballast, which controls the ignition and light maintenance, are additionally characterized by high quality lighting and durability. - luminaires for clean rooms are special-purpose devices, in the case of which the quality of workmanship affects not only comfort, but also work safety. The products in this category available on the el.12 website are characterized by, among others: very good parameters in terms of fire protection class, degree of protection (IP65), impact resistance (IK08) and protection class (I class). - channel luminaires are devices that will work mainly as a lighting element for garages, parking lots, various types of workshops, as well as basements, communication routes or staircases. The channel luminaire is distinguished not only by high resistance and durability, but also - if it has been equipped with a LED light source - also by energy efficiency. - workshop lamps. In the case of workshops, surface-mounted and suspended luminaires are most often used. The choice of a specific model depends on the conditions in a given room, its size and access to natural light. The general rule, however, is that general lighting should be supported by additional spotlights in places where precise work is carried out (e.g. above the table or near devices). When it comes to ceiling workshop lamps, one of the most popular solutions are linear fluorescent lamps, more and more often in the energy-saving LED version. Fluorescent lamps are characterized by extremely high resistance to overheating, as well as longer working time. Workshop lamps can also be found in a portable version (wireless or cable-powered), which increases the convenience and safety of their use when you need to illuminate some hard-to-reach space (e.g. engine or car chassis). Efficiency and durability of specialist, surface-mounted and industrial lighting In order for the applied lighting to be optimal and safe, it is necessary to take care of light sources characterized by appropriate efficiency, which is measured by the luminous efficiency index (lm / W). This parameter determines how much light is produced using one watt of electricity. The highest degree of efficiency is characterized by LED lamps (up to 135 lm/W), while the lowest - fluorescent lamps and halogen lamps (5 - 27). For this reason, the latter are rather unsuitable for industrial lighting. They are intended rather for use in households where lighting is used only a few hours a day. An important feature is also the lifetime of the light source. LED sources are the longest and metal halide lamps are the shortest. Information about these indicators should be found on the bulb packaging.
