OptoDrive™

A new generation of light sources with integrated electronics.

The OptoDrive™ LED-module

Heat radiation

For all light sources the conversion of energy to light is not a 100% effective process. In traditional light sources much of the converted energy to heat and emitted as infrared light. With much better efficiency LEDs provide lower power consumption and less heat.

LED solutions do not emit heat as infrared light, so it must be removed in other ways: for example by an appropriate heat sink. Therefore, the LED solutions usually made on an aluminum base which transfers the heat completely out of the module.

Exchangeability

The OptoDrive LED module is classified as integral built-in LED module according to IEC 62031 and is expected to be mounted in one place for the lifetime of the light fitting. If it is to be exchanged it should be done by the light fitting manufacturer.

Efficiency of LED-module

The module efficiency is shown in the datasheet in each individual intensity bin code. This is for guidance and as a tool for energy calculation.

The efficiency is noted in the unit Lm/W.

For the ID (Internal Driver) and AC (Altering Current) modules the efficiency includes the on board driver. For the ED (External Driver) modules where the driver is not included onboard the efficiency has to be completed depending of which driver being used.

White LED’s are today emitting light of 100 lumen / Watt in comparison to the incandescent-bulbs that give about 10 – 20 lumen / Watt.

Light adjustment range (Dimming)

The different module versions, ED-External driver, ID-Built In driver and AC require different set ups for dimming.
ED: Standard PWM dimming or current dimming

ID: Standard PWM dimming*

AC: Standard Triac dimmers

* For PWM dimming the DimLight product is available in different versions.

Ambient temperature

Since the OptoDrive LED modules are designed to be integral or built-in LED modules the ambient temperature (Ta) cannot be specify as the heat sink is thermally connected to the LED modules.

The module is depending on the light fitting and its cooling ability. The temperature range of the modules is related to the temperature of its junction temperature (Tj) and is verified by measuring the temperature of the module at the PCB (Tc temp). The Tc temp is for each model specified in the datasheet.

Durability

Vibrations has no effect on the emitted light since there are no moving parts inside a solid state solution.

Environmental friendly

The differences compared to other light sources are that they are not using any light filaments and they are not filled with any kind of gas. They are very environmental friendly in compression and do not require as much energy as many other light sources. The LED’s have been used since the 1960s and was initially used in electronic devices.

All our LED modules meet the Restrictions of Hazardous Substances (RoHS)!

There has been a growing consensus that Lead Free Systems should increase for the safety of our environment. It is a very serious problem that lead and other harmful materials are being used in commercial and industrial products, causing more and more environmental problems. This has led to regulations such as RoHS (Restriction of the use of certain Hazardous Substances) from the EU and the Japan Ministry of Trade and Industry (MITI). All LED module makers providing products to these countries should comply with these restrictions. In order to meet the RoHS regulation, Optoga is strictly implementing a ban on lead and other hazardous materials in its products. This is in compliance with our responsibilities as good corporate citizens.

The light of LED

What is Solid State Lighting?

SSL (Solid State Lighting) is often mentioned when talking about light sources based on LED technology. The term “solid state” refers to light emitted from a solid object: such as an LED, rather than from a vacuum or gas pipes as in the traditional incandescent and fluorescent lamps.

LEDs are semiconductors that convert electricity into light. Originally LED was used as indicator lamps in electronics. Now, LEDs developed into a lighting technology that changed the future for general illumination.

LEDs are highly appreciated for their long life, energy efficiency, non-toxicity, durability and flexibility.

Light exchange

The luminous efficacy is measured in lux and fulfills its function as a reference value on an illuminated surface.

The contrasts needs to exist between darker and lighter areas but it must not be too large differences.

Lighting surface must be defined in a good way for the fixture to be used optimally. Therefore, a standard developed by the Nobia Group for how the fixture should be mounted in the base units for optimum light image.

Luminous flux

Luminous flux is measured in the lumen (lm) and makes sense to include as a guideline of a luminaire for general lighting.

The luminous flux is the total amount of light and it will be on par with today’s customary solutions.

Colour rendering

Colour Rendering Index or CRI is affected by light spectral composition, therefore, the requirement is that light and colors should be experienced natural and pleasant.

The color rendering is described with an Ra value. On the part of work environment it is good if Ra value is as high as possible, this should be included as an important parameter in the evaluation of lamps and light source.

Colour Rendering Index (CRI) is one of the most important factors to ensure good light. The light emitted from a light source bounces off an object and back to the eye. If it has a high CRI we perceive colors and shapes better and environment will be experienced more natural and colorful.

If we increase the color rendering (CRI), we can decrease the brightness. Compared with a light source with lower CRI we get the impression that both create the same amount of light. High CRI provides higher contrast!

Those who work in higher CRI feel less stress and less fatigue.

Colour temperature

Colour temperature as specified in CCT and Kelvin based on CIE 1931 and specific bin codes.

The fixture

Construction

The construction of the fixture will secure operating temperature of the LED module using convection.

It shall also aesthetically be sustainable and able to quickly and easily be mounted by an electrician. Preferably the same shape and size as halogen lamps for simplicity.

Light distribution angle

The light distribution angle is relevant to how the fixtures are constructed and how much space they can illuminate.

Too large light distribution angle can lead to glare.
