DEVELOPMENT ON REQUEST
STREET LUMINAIRES
• Full new street LED luminaires
• Parts of the new luminaire (a new design, optical solution, thermal solution etc)
• The upgrade of an existing luminaire
SUPPORT OF ILUMTECH WITH THE DEVELOPMENT
LED luminaires are generally equipped with aluminium heatsinks due to the high thermal conductivity and low weight of the material. However, it is possible to minimise the use of aluminium and achieve improved heat transfer performance in larger luminaires by using plastic heatsinks embedded with an aluminium heat spreader. The used plastic, such as polycarbonate (PC), high density polyethylene (HDPE) or polypropylene copolymer (PPCO), may not be enough to cool the luminaire necessitating the use of a heat spreader under the heat source to increase heat dissipation. The use of injection moulded plastics opens up flexibility in terms of the geometric structure of the heatsinks, which can be easily optimised for convection heat transfer. Plastic is also approximately 40 % lighter than aluminium, which ensures better resistance to shock and vibration, in addition to having no antenna effect resulting in reduction of EMI. The result of these factors is increased heat transfer performance, weight reduction, cost saving and ease of manufacture.

THE MOST SUITABLE OPTICAL SOLUTIONThe development of LED street lighting optics can be approached in two ways:
a) Standard solution – by using standard optics available on the market (lenses, reflectors)
b) Optimised solution – the optical system can be optimised according to application and customer requirement:
- Street lighting configurator – thanks to this tool we can combine existing lenses on the market to create the requested LIDC
- Design of a new optical system (lenses or reflector)
Standard solutions Customer solutions

STREET LIGHTING CONFIGURATOR
The Street Lighting Configurator is a tool which combines existing lenses on the market to create the requested LIDC.
the configurator uses 4 different lenses with different intensity curves and calculates
256 combinations with rotation steps 90°
it is possible to insert the LDT of any lens into the configurator
it is possible to modify the rotation step
the configurator can be extended to work with more LID curves
the configurator can be used to mix different luminous intensity curves

Refractor and diffuser selection It is difficult to understand the advan-tages and disadvantages of each type of refractive or non-refractive diffuser, especially in terms of its application in a specific setting. Our optical engineers are experienced in making these choices and can help customer understand which best suits their needs.
Refractor optimisation It is possible to modify a refractive ma-terial in order to achieve a desired LIDC; however, this is an incredibly difficult task that requires a high level of expertise. To help us with this process we have devel-oped our own LIDC Optimiser software, which helps us determine the precise LIDC needed for each application and provides calculations we can use as a base for opti-cal optimisation.
Refractor design There are a variety of refractive optics used in illumination systems. In this group we can find lenses, arrays, prisms, pillow optics and also protective covers. The abil-ity of these opitcal parts to directly control the light is due to the law of refraction. Based on this great flexibility, we are able to creat any refractor design according to customer needs.
Lens optimisation Lenses are used in LED luminaires and are commonly positioned directly on the LED. There are many lens shapes to choose from. Only experienced and knowledge-able optical engineers know how to de-termine the best lens for each product, with the possibility of combining various lenses within one optical system in order to achieve the desired result. For highly demanding street lighting luminaires we have developed our own optimisation software, the Street Light Configurator, which allows us to combine up to four dif-ferent lenses at various angles in order to provide the needed LIDC.
Lens design Lenses are standard parts in optical design. Illumination designs use internal reflection and the law of refraction to cap-ture the light emitted by a light source. In most cases we use free form lenses. This will be an area of focus in ourfuture de-signs, as such lenses are incredibly flexible and can be used in variety of applications.
