Several light sources connected in serial or parallel to the same driver

Uncategorized No Comments

Third document of our technical news serial is focused on other question repeated over the time that  we have to explain it constantly. Clients  ask  for information regarding the use of one constant current driver to feed several light sources.

Remembering last article, our luminaires integrate two components, one driver or converter and one light source. T his configuration it is highly recommended by us and we always indicate the use of our products  following this so we do not recommend  the connection, in serial or parallel, of several light sources in a  single driver or converter.

Recommendable Connection

Above you can see the explanation because of JISO ILUMINACIÓN, SL. does not recommend the connection, in serial or parallel, of several light souces in a single driver or converter.

Parallel Connection

This kind of connection would be the less recommendable so, when we connect several light sources to a single driver or converter, the driver has to be able to feed a current (contantly) equal to the sum of the design currents of the light sources associated.

For example, If we connect 3 light sources designed to work with 300mA, then, the associated driver or converter must be able to supply 900mA.

The problem appears when one light source is not connected properly, or it appears a failure, or any source does not receive the energy correctly, so, in that case, the current, which should be divided equally between light sources, it is divided incorrectly and the other light sources received more current than the one they need.

For example, in the example shown above, if one light source is not switched on it is produced, as a result, an increasement in the current of the others and, in that case, instead of 300mA, each light source will receive 450mA. This can generate an overheat in the light sources and the consequent failure. If one more light source fails then the last one will receive 900mA so in a small period of time it will fail as well.

Parallel Connection

Serial Connection

This kind of connection, although it is less problematic to the light sources, it  would not be recommendable either. In this case the driver has to be able to supply the design current (constantly) of the light sources and, besides, it has  to be included, in its voltage range, the sum of the voltages of the light sources (the load of each light source).

For example, if we connect 3 light sources which are designed to work with 300mA and 36V, then the associted driver or converter has to be able to supply 300mA and within its voltage range will have to include the sum of the three voltages (108V). For example, a voltage range of 75-120V.

The problem appears when one light source is not connected properly, or it appears a failure, or any source does not receive the energy correctly, so, in that  case, the continuity of the system is broken.

For example, in the example shown above, if the light sources are not switched on, the continuity of the system disappears and, as a result, every single light source is switched off and we never know exactly where the problem is focused so we will have to waste time in order to find out the problem.

Serial Connection

Therefore, JISO ILUMINACIÓN, SL. only supply luminaires which integrate one light source and one driver or converter, and we do not recommend the use of any other kind of connection in other to keep the warranty available because  otherwise the warranty will disappear.

Brightness reduction

Uncategorized No Comments


The second instalment of our technical news serial is focussed on one question which is becoming common in installation where our products are used but where customers need less brightness than luminaires generate normally.

In this case we have, taking into account products indicated to work with constant current drivers, two options:

  1. Use of a dimmable driver regulating the brightness with a compatible dimmer.
  2. Use of a driver with lower current than standard current of the product but with an output voltage range in Direct Current (DC) in which the voltage of the luminaire is included.

Option 1 would be the most recommendable so it allows a better integration of the product in the area where installed and, besides, it provides the possibility of variate the brightness when necessary. However, and once said this, in following paragraphs we are going to talk about the second option as this is the one demanded from customers and it is the most unknown as well. In future documents we will write about issues related to brightness regulation by using different kind of dimmable drivers and their accessories to be controlled.

We must take into account we have two different items in luminaires; on the one hand we have a driver or converter, which converts the supply from altered current (AC) to DC, and, on the other hand, we have the light source, which works in DC and is fed by the driver.

Therefore, when a luminaire is designed the specifications related to current and voltage, in DC, of the light source integrated must be taken into account because the coupled driver must be able to meet them.

For example, if we have a light source running with 700mA and 36V, then we need to feed it with a constant current driver not only supplying 700mA (continuously) but also with a voltage range in which 36V is included (it could be 27-42V, for example).

In the previous example the luminaire would be working in optimal conditions. But there is a chance, when possible, of modifying the way to supply the current from the driver (with lower values), in order to reduce the power consumed and supplied by the luminaire, permanently and without any possibility of changing it by using any dimmer.

For example, using the same light source as before (700mA and 36V), we could couple it with a constant current driver which supplies 350mA and with a voltage range in which 36V is included (it could be 27-42V, for example). Therefore, thanks to the driver with 350mA we get half power, consumed and supplied, to be used in installations which require this effect. 

Obviously, the information indicated above could not be possible in all cases so it is mandatory to use drivers which are able to meet with the features of the light source, regarding to voltage and the current they supply. Normally, the luminaires in which the light source works with 300/350mA do not have the chance to reduce their brightness by this way and, as a result, they need to be regulated by using a dimmable driver.

If you need a product with the features we have described do not hesitate to contact us and we will help you to study and define the best method to get it.

Central Battery System for Lighting in Emergency Cases

Uncategorized No Comments

In recent times we have received several questions and requests relating to the necessity of lighting compatible with Central Battery Systems (CBS). Consequently, JISO ILUMINACION, SL. has decided to begin its News writing about it.

Before starting, it is highly important to have into account that the luminaires supplied by JISO ILUMINACIÓN, SL. are NOT emergency luminaires and that the systems we are talking about do NOT make them emergency luminaires either. These systems just allow the luminaires to continue running for a specific period of time after an electrical shut down.

Besides, a distinction must be made between the two typical systems which supply energy in emergency cases: on the one hand, there are Centralized Systems (Central Battery Systems – CBS), in which a centralization of batteries feed the luminaires in direct current (DC) allowing to achieve a similar power than with a normal supply and, on the other hand, there are Decentralized Systems (EM Kit – Emergency Kit) in which each luminaire has an individual supply system with one or more batteries feeding it in DC, allowing to achieve a power between 3W and 7W. In this article we are going to focus on CBS only.


Focusing now on the matter of the present document, CBS integrate a central module, one single battery or a bank of batteries and the luminaires associated, together with the cables required to make the connections. The luminaires, which are the elements where JISO ILUMINACIÓN, SL. takes part in, can be not only conventional emergency luminaires (NOT supplied by JISO ILUMINACIÓN, SL.) but also luminaires integrated in the lighting circuit which, maybe all of them or maybe someone located strategically, are intended to keep running after a main supply failure. In this case, normally, unlike the applications with EM Kit, the luminaire will have the same brightness as when working fed by the main supply, but it will be fed in DC from the batteries instead of alternating current (AC). Therefore, the drivers of the luminaires integrating the installation must meet specific requirements because they will have to be able to be fed by AC and DC. Besides, they will have to meet with the voltage input ranges of the central battery supplies, so that not all drivers will be able to be used with this kind of system.


JISO ILUMINACIÓN, SL., after several projects with CBS, has decided to create a new reference code for the luminaires prepared to be coupled with a driver compatible with CBS. This code can be identified with a 7 placed after the first five numbers of the references (ex.: 51022-7284-90). Therefore, customers will be able to detect those luminaires which are compatible with CBS in our new catalogue as well as they will find information regarding CBS.

JISO Lighting raffles two drones to the guests at Light & Building 2018

Uncategorized No Comments


JISO Lighting has now drawn the drone winners out of everyone who took part during Light & Building 2018, an international trade fair for the lighting sector that was held in Frankfurt (Germany) last March.

The JISO Lighting stall had a great flow of people who were interested in all our products, both interior and exterior. In addition, at this edition of Light & Building, JISO Lighting wanted to showcase something very special to their visitors. After considering all the options, they went with drones because of the small aircraft’s popularity and people’s interest in them for both leisure and their many uses in the field. Therefore, everyone who visited the JISO stall could put their card into a hat! Loads of people took part and the draw was held at the company’s site in Chiva (Spain) on the 14thof August.

The lucky winners were Ahmed from Dubai (United Arab Emirates) and Lea Tabcharani from Doha (Qatar). Both offer lighting solutions in their respective countries, based on quality, design and great value.

This competition was one of the attractions at the JISO Lighting stall at Light & Building 2018, where all our company’s innovation was on display to architects, designers, decorators, buyers and professionals in the sector. The space was designed by JISO director, Mª Carmen Giménez. It was an elegant space with LED technology and contemporary designs by the Valencian company.

As well as all the innovation and luminaire ranges available in the JISO Lighting 2018 catalogue, the new outdoor luminaires and the brand-new Nature Dome were also showcased, a light inspired by nature with handmade decorative features. Fresh designs, with handcrafted and personalised finishes, that attracted the interest of those taking part in the competition. All our products are of course, designed so that JISO Lighting customers can have exclusive and custom lighting.

All this in a large area with interactive zones to try our adjustable lighting controls, as well as tablets to browse the latest designs. Also, at the stall there was a small bar so our guests could have a drink while chatting and a photocall featuring the raffle box.

The international Light & Building fair in Frankfurt, which takes place every two years, is one of the most important events in the lighting sector. It brings together three extremely relevant areas of building planning: lighting, electrotechnical and home-automation. In addition, certain architectural services are also displayed. It unites more than 2,700 exhibitors from 55 countries and more than 200,000 visitors. JISO Lighting, just as in previous editions, was one of the 104 Spanish companies that exhibited their products and lighting solutions at the event.

Safety, reliability and savings with the Jiso Lighting Industrial Collection

Uncategorized No Comments


When choosing the lighting for an industrial building, you have to think about the safety and comfort for the employees. Reducing levels of visual fatigue, providing good visibility and ensuring welfare within the company are three factors that influence the quality of production. Something this is certainly in the company’s best interest.

However, we must also bear in mind energy savings. According to the Institute for Diversification and Saving of Energy (IDAE), the industrial sector is responsible for 31% of energy consumption in Spain. In addition, 10% of the electricity bill of a manufacturing facility comes from lighting expenses. Therefore, it is important that the luminaires chosen to light that establishment use LED technology. This technology provides great energy savings, a longer life compared to traditional bulbs, as well as a significant reduction in costs, both in maintenance and in the electricity bill.

At JISO Lighting, both these notions are at the forefront of our Industrial Collection. The four models of luminaires have LED technology, which maximises their lifespan and, in addition, they offer an optimal heat dispersion. These models can be used both outside and inside, and they each have their own significant advantages.

Our new high-bay 05 offers great reliability, thanks to its LIFUD driver, and has a 5 year warranty. Its new design and lighter weight make it easier to install, while remaining robust and highly vibration resistant. This model is available in 4000k light, which gives a neutral light, very similar to the natural one, or in 6000k light, which is cool light that generates a perception of greater luminosity (similar to that of a very sunny day). This industrial high-bay is designed to be installed suspended and is suitable for conditions with large amounts of dirt, dust, humidity and extreme conditions.

The 008 and 08 models are projectors specifically designed for outdoor lighting, but they can also be used inside buildings and work areas. Their attractive design makes them ideal for small walls, outdoor furniture, doors or pergolas for example. They are available in cool or neutral light and in different sizes, so you can choose exactly what you need. Models 008 and 08 stand out for their energy efficiency, reliability and long lifespan.

Another surface model of the industrial collection is the water-proof screen  (model 004). They are also designed for outdoors but are perfect for industrial use, such as interior building lighting, due to the lighting capacity they offer, as well as their level of energy efficiency and their high-quality waterproofing, which protects them from moisture and external particles. The JISO Lighting water-proof screen are available in different sizes, to fit your needs, and in 4000k (neutral light), although we do stock some with 6000k light (cool light), if you need it. At JISO Lighting we have a wide range of products to help you choose the best for your company.
