Photometry

Photometry exposed are the most commonly used for outdoor lighting. In addition to these , we have a wide range of lenses for

any specific lighting requirement or space to iluminate.



Range of luminaire KOKOH

The luminaires developed by KOKOH are encompassed in three categories:

• Base

• Preprogrammed

• Premium

All ranges share the know-how of KOKOH such as quality of materials luminaires, the use of the latest generation LEDs with high

lumen/watt ratio, in combination with high-performance lenses and photometry optimized for any type of lighting, optical block

formed by a heat sink that combines high thermal conductivity with high mechanical strength and switching power supply with an

efficiency of 92% and low ripple output voltage.

The Preprogrammed and Premium range combines quality and technology described in the added value of drivers developed by

the R + D + i of KOKOH RESEARCH, which offer additional features such as additional protection against surges and overtemperatu-

re in led node, variation the luminous flux, remote management point to point and are fully compatible with technological

advances developed by our R + D + i.

Our drivers control are the result of years of study of our R+D+i on the operation of LED tech-

nology.

Offer greater benefit in the overall performance of the luminaire, as in the life of the LED.

Drivers developed by KOKOH are constantly evolving according to the latest technological

advances in led technology.

The advantages of the use of our drivers are as follows

1. Minimize the risk of failure by improper operation of the LED

Our optical blocks are designed such that failure of one LED does not affect more than a quarter of the total LED luminaire. The

LED module is configured in 4 separate arrays of 6 LEDs (L24 version) or 2 arrays of 6 LEDs (L18 version) connected in series and

controlled by the driver KOKOH. With this configuration the LEDs will consume the same power independently without the need

of balanced circuits and in case of failure of a LED, the maximum affection will be only 6 LED of all LED that make the fixture.

2. Protection against surges, transients and high voltages

In order to offer the highest reliability and safety in our luminaires and lighting equipment, the KOKOH driver has additional pro-

tection in addition to the power supply capable of protecting the driver, control electronics and LED modules against possible

Anomalies that may appear on the power line such as atmospheric surge, transients and accidental cut of the neutral conductor of

the network. This protection is independent of the surge arresters to be installed in the public lighting panel and at no time repla-

ces them.


ESFERA KOKOH - GENERIC INFO DATA SHEET 3. Protection against high temperatures

In the event of a sudden increase in temperature, the KOKOH driver has temperature sensors that monitor the heat emitted by the

luminaire at all times, acting in the event of an abnormality to protect the whole of the equipment from premature failure by a

Excess heat.

4. Variation of the luminous flux

The driver developed by KOKOH allows the variation of luminous flux of the luminaire and consequently to minimize the energy

consumption of the installation to obtain an additional saving in the hours of less use of the installation.

Our R & D department has been able to develop various methods of variation of luminous flux depending on the characteristics of

the installation where the luminaires will be located.

In the case of traditional installations replacing luminaires with discharge lamp technology by LED luminaires, the KOKOH drivers

allow you to take advantage of dual level lightning control line or luminous flux regulators with voltage stabilization as used for

sodium lamps( No matter the model), to reduce the power consumed by luminaires at night. This last quality perpetuates the li fe

of the luminous flux regulators , which after the entry of LED technology had been relegated to the background because they are

incompatible.

For installations where there are no luminous flux regulators methods or for new installations, the KOKOH drivers allow self-

regulation without the need for an external signal. For this it has a programming capable of assigning up to 8 steps of control so as

to vary the power consumed as a function of the time that is in progress. This feature is performed by the programmable version.

The self-programmable version has autonomous capacity of auto-adjust regulation according to the time of the year, since the

regulation needs are not the same for summer as for winter. Thanks to its complex algorithms of control, the KOKOH driver can

discriminate in which time of the year it is and self-adjusting its steps according to the hours of darkness in each moment.

5. Remote management

The future of outdoor lighting through integration of this within the Smart City concept. It allows sustainable development of ligh-

ting with less consumption of energy resources and greater capacity of infrastructure management. Our R & D has developed dri-

vers that have the ability to be integrated into a Smart City for remote management through a communication module, managing

to control all operating parameters of the light (on schedule, variation luminous flux) and know in real time consumption, hours of

operation, breakdowns...


ESFERA KOKOH - GENERIC INFO DATA SHEET LED thermal management

It is known that the lifetime of the LED and the luminous flux emitted is related to this junction temperature reached in normal

use. Our R & D has endeavored to reduce the temperature by developing a heat sink to ensure maximum heat dissipation of the

LED and turn the sink reaches a minimum surface temperature.

The heat sink used in luminaires KOKOH, is designed for maximum heat dissipation thanks to design your fins, dissipation Surface

and the thickness of the base in contact with the LED. The heat sink is made of extruded according to DIN EN 12020, the material

used is aluminum tempered according to EN AW 6060-T66, topped with a black anodized color over the whole surface.

This combination makes our heatsinks one of the most efficient in the market.

Retrofit

The retrofit is defined as the modernization of one of the parts of a machine, system or element whose factory parts have already

lost their performance product of years of use or obsolete by advancing technology. In the case of conventional luminaires, the

retrofit involves replacing optical block by another based on LED technology and with

the advantages that entails: high luminous efficiency, lower energy consumption, lon-

ger lifetime... and at the same time, the change and the elements used must meet the

electrical and safety regulations.

Our optical blocks, based on LED technology, are 100% compatible with the retrofit

being accredited according to Directive 2004/108/EC EMC, Directive 2006/95/EC Low

Voltage and Directive 2009/125/EC Requirements ecological design.

As manufacturers, we can make the retrofit luminaires that has the client installed,

serving them with all approvals of the assembly formed by the existing luminaire's op-

tical equipment KOKOH according to European Regulation (CE).

Heat sink tempered aluminum extrusion profile according to

standard DIN EN 12020

The ESFERA luminaire is suitable for installation on columns with Ø 48 or Ø 60 mm inlet.

Mounting height between 3 and 5 meters, adapting to any light need thanks to its studied optics.

Very suitable for installation in urban environments, residential areas, parks and gardens.

Adaptable to future technological improvements developed by our R & D & I department.
