JISO Smart Control

JISO ILUMINACION, after the exceptional feedback received with its LED Strips Control System, has decided to extend it, apart from the LED Strips, to a bigger rate of product in order to control downlights, spotlights, panels, bulbs and even to switch On/Off different items which are not dimmable. Besides, with the main objective of making life easier to our customers, the control has been universalized with the introduction of PanelTactil 32, the future launching of Switch 32 and the developing of the JISO APP which joint to the reference JISO SmartWifi will allow to customers the lighting control via Mobile Phones or Tablets with software Android or IOs.

In the previous scheme it is possible to see the JISO Smart Control system with and its components. Control devices (Mando 32, PanelTactil 32, Switchs and mobile device) are located in the middle, next to them we find the controllers (Control-V10/20/31/32, Control-C10 y S-10, SmartDriver 15/36, bulb 1LHE-CR9, floodlight 01810-C98R-01 and Socket 10), which are managed with the control devices, and, finally, the lighting devices in which the control is done (LED Strips, downlight, spotlights, panels, etc.).

JISO Smart Control system offers, to the final user, to opportunity to take advantages of a customized control, economic, with easy installation and easy use, in which additional wiring will not be necessary thanks to the 2.4GHz wireless signal.

Light remnant

Light remnant is one of the main headaches connected to the use of LED luminaires

Light remnant is one of the main headaches connected to the use of LED luminaires when light is “switched off”. That is why JISO ILUMINACIÓN has decided to write about this issue.

LED technology, although apparently similar to traditional lighting, has differences which must be taken into account for their normal functioning:

General recommendations:

1- Firstly, follow the installation and connection order for the different elements:

• Perform line checks, the neutral without direct current to DRIVER/LUMINARY and the phases to switch elements.
• Connection order: connect the LED luminary to your DRIVER, then connect the Driver to the Line and finally introduce the current.

2- Each DRIVER with the appropriate LED luminary!

The power supplies (DRIVERS) are electronic devices and not merely transformers. They deliver regulated voltages and currents and have direct current outputs, so respect connections and polarities.

CAUTION especially in installations which feature different LED luminary models. Check the driver, the type of current, the voltage and the polarity, taking into account that the current can be 300mA, 350mA, 600mA, 700mA, 1000mA, etc., and that the output current of the driver is continuous.

3- Wiring. Splices and Connections.

It is important to use suitable section wiring, considering that the current required is very small. The splices require welding and insulation with heat shrink tubing or tape. Observe the connections, whether they are series or in parallel according to the manufacturer’s installation recommendations.

4- It may be that the LED luminary is giving off any light but always remember that current is still circulating in the system.

If you encounter any issue, please give us the opportunity to resolve it before returning the product. Most technical assistance questions can be answered through our knowledge base on the website: www. jisoiluminacion.com, or via the technical support service by email: asistenciatecnica@jisoiluminacion.com. The use of the electronic elements and parts of the installations can cause some very specific and sporadic incidents which do not damage the LEDs but which are striking, such as residual luminescence (brightness), flickering or switching off shortly after installation (temporary block which works by removing and returning the switch).

All these effects existed previously but were not detected because lighting technologies were not as efficient; a lot of energy was needed for their operation and the “residual” voltages, the induction generated voltages, the commuted point installations and the mechanisms with light signal did not affect them.

Most frequent causes of the effects mentioned above:

1- The switches of the electrical installation cut the neutral whereby the phase reaches the LED.

2- Current flows through the neutral, due to earthing shunt or other causes.

3- Induced current. This can be generated by the presence of large household appliances or industrial  achinery.

4- Pilot signalling switches (Neon or LED). This type of switch admits a current of 12 to 30 volts.

5- In switched-point installations, a residual voltage may be produced (due to the length of the crossing lines) which acts as a capacitor generating small voltages which can maintain some brightness, flickering or blocking of the LED luminary driver.

6- The installation has two active poles so there is always potential in one pole of the driver.

7- The ceiling where the luminaire is placed has electrical conductivity and, as a result, the contact between the ceiling and the luminaire body thanks to the existence of an active pole connected, makes possible to have potential and remaining light.

Possible solutions:

In points 1, 2 and 5, we recommend checking the electrical installation.

Neutral direct to Driver – Phase to switch

Image 1. LED luminary connection diagram + switch

To easily check if it is neutral or phase, we can use a pole detector, or Multimeter/Tester.

- When you touch the phase conductor with a pole detector, the neon light shines. In the new models with a LCD display showing the voltage, when you touch the phase it will read 220V.

- In pole detectors, neither the neutral nor the earth triggers the neon light. And in the pole detectors with a LCD display, no voltage is indicated for the neutral or earth.

With the Multimeter or tester using Voltmeter AC 750V function

Between phases – neutral 220V-240V will be indicated.

 Between neutral and earth 0V.

And between phase-earth 220V-240V.

Another possible solution in cases of residual current would be to install a capacitor of 0.47uF 400V (Solution points 3 and 4).

Image 2. Condenser REF. DCCONDEN-1

You can also use bipolar switches or contactors to count the current flow to the lighting lines. (Solution points 3 and 4.

This last mechanism would allow, in any case, to eliminate the remnant of light so, when the power in the driver is removed, the driver could not be put in tension in any case.

Technical Deparment

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

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.

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.

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.

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

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

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

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 14^thof 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.
