Optec for track
The key design feature of the Optec spotlight range is the separation of light head and control gear housing. The thermally separated mounting compartment ensures excellent heat management for the electronic control gear of the lamps. Because of the comprehensive system structure with its various lamp options and beam angles, Optec is particularly ideal for lighting sales areas, restaurants or galleries. The relationship between visual comfort and light output ratio is optimised for the wide range of applications of these spotlights. The different characteristics and the robust aluminium luminaire housings have stood the test in many practical applications.
The successful Optec range of spotlights already features the second generation of LED spotlights: with interchangeable Spherolit lenses, optimised light heads for increased luminous flux from more compact housings - and as a special feature in the range, an LED projection spotlight with framing attachment.

Different lighting concepts require luminaires with precisely adapted lumen packages. The Optec product range features assorted wattages in a uniform design with adapted housing sizes, which are easy to combine.
The projector spotlight with framing attachment produces sharp-edged beams. This, for instance, creates the effect of a crisp focused beam illuminating an image that appears to be self-illuminating. Made of polycarbonate, the framing attachment of the LED projector spotlight ensures easy sizing of the projection area. The projection lens can be adjusted to set the sharpness of the progression.
Adjusting the projection area
The projection area is increased by pulling out the framing attachment. Perspective distortion is balanced through rotation of the attachment.
Setting the sharpness
The sharpness of beam edges is set by adjusting the lens holder.
ERCO places particular importance on heat management. This ensures that LED modules operate within their safe temperature range, achieving rated life and output for the specified power throughout their entire operational life.
Dimming on the spotlight
Spotlights can be dimmed in various ways for efficient visual comfort. The versions with electronic control gear developed by ERCO have an integrated potentiometer to adjust the luminous flux precisely and individually.
Dimming via circuit or DALI
Spotlights with potentiometer can also be operated by external trailing-edge dimmers. This makes them ideal for an energy-efficient renovation of existing lighting installations which are equipped with this widely used dimmer technology. Alternatively, spotlights are also available as DALI-compatible Light Clients.
The modules of the varychrome RGBW luminaires consist of a combination of warm white and coloured LEDs. This allows for excellent colour rendering and infinite adjustment of the colour temperature.
Used to accentuate small objects with high light intensity or to project over greater distances between the luminaire and the target object. Beam angle < 10°.
This is the standard characteristic for accent lighting for objects of all kinds, especially to reveal the three-dimensional shape. Beam angle 10°-20°.
Used for efficient accentuation of large objects or to uniformly emphasise a complete spatial zone. Beam angle 25°-35°.
Used for flexible, flooding illumination of surface areas and spatial zones, especially useful for the presentation of goods. Beam angle: > 45°.
The Spherolit lens or Spherolit reflector, oval flood, has an axially symmetrical light intensity distribution. It produces an oval beam of about 20° by 60°.
The light intensity distribution of the lens wallwasher is designed to provide very high uniformity.
The quality of the optical systems has a major influence on the overall efficiency of an LED. To produce directed light, as occurs in spotlights, ERCO develops their optical projection systems in-house. A collimating lens, as a secondary lens, is the interface between the LED lens on the printed circuit board and the exchangeable Spherolit lenses acting as tertiary lenses. The collimating lens directs the light of the LEDs into a parallel beam in order that the required light distribution can then be created by the tertiary lens. The principle of total internal reflection in the collimating lens contributes to the high efficiency of the optical system. Decades of experience in injection-moulded polymers ensure the highest quality levels from our in-house production plant.
The radiation spectrum of warm white LEDs is free of ultraviolet and infrared components and has a reduced blue component. Its relative damage factor for sensitive exhibits is less than for halogen lamps with UV filters, making warm white LEDs recommendable for museum lighting.
Characteristics of LEDs
Warm white LEDs
The relative spectral distribution of the warm white LED with luminescence conversion is closely related to the relative brightness sensitivity of the cone cells of the human eye. The result is high luminous efficacy and good colour rendition.
The RGB LEDs are ideal for mixing highly saturated coloured light. However, the white light from RGB LEDs does not give satisfactory colour rendition quality, making it less suitable for lighting tasks where colour is critical.
Mixing RGB LEDs with warm white LEDs combines the advantages of both systems: RGBW luminaires produce variable shades of white along the Planckian curve with excellent colour rendering, but also coloured light in pastel hues all the way to the highly saturated range.
LEDs (Light Emitting Diodes) are semiconductor elements that directly convert electrical energy into light via electro-luminescence. The outstanding characteristics of LEDs include robustness, long functional life and a high luminous efficacy with high potential for further increase. White LED-light is free of ultraviolet and infrared components and therefore has advantages from a conservation point of view. Daylight white LEDs offer higher efficiency, whereas warm white LEDs have better colour rendition quality. LEDs are dimmable and offer high switching stability, making them ideally suited for lighting control and additive colour mixing. Unlike other light sources, RGB LEDs do not produce any transmission losses through colour filters. To exploit the luminous flux of the temperature sensitive LEDs to the full, good thermal management is indispensable.
