Use of LED lighters

The LED lighters DL1 series are indicate for the realization of artificial vision systems. The lighter is placed in a way to illuminate the object (or the single object zone) that must to be controlled. It's therefore possible to determine dimensional parameters (width, position, distance etc.. ) or of defective state parameters (spots, deformations, holes, material absence, etc... ) or the character and barcode reading

The employment of LED lighters in the field of artificial vision is a consolidated and diffused reality above all for the advantages that derive from the use of semiconductor luminous sources (LED) between wich the long working life of the lighter, the good homogeneity of the illuminated field, the possibility to choose the wavelength and therefore the emitted light colour, the possibility to realize lighters with innumerables shapes and dimensions, the easiness of regulation and modulation of the emitted light.

The LED Lighters DL1 Series distinguish theirselves also for :

Economic Series without protective glass

Sturdy container in anodized aluminium in a position to conferring an high twisting rigidity and an optimal resistance to the bending also for lighters of particularly elevated lengths.
The construction has been studied in order to allow the employment of these lighters also on machines and systems that don't have suitable fixing supports for the entire length of lighter. The two fixing points, situate near the two extremities of the lighter, are sufficient to maintain in rectilinear position the entire lighter.
Efficient heat dissipation system produced from the luminous source. The dissipation system was designed in order to transfer towards the external walls of the lighter the maximum amount of heat. The developped heat is entrusted to particular dissipated materials, derivated from materials developped in the aerospace field.
High reliability and long duration of the luminous source have been obtained by the employment of semiconductor LED at high efficiency, thanks to the most modern optoelectronics technologies. The average life of of a LED source at semiconductor, correctly fed and working at temperatures inside of the admitted limit, exceed abundantly the 100.000 hours.
Modular structure in a position to allowing the construction of lighters with different dimensions of the lighting range. The employment of a modular structure allows the construction of lighters that can measure from a minimum dimension of few mm up to dimensions of mt.

HTTM Technology

LED lighters DL1 series employ the HTTM technology (High Thermal Transmission Material – RODER Electronics Trademark) in order to transfer the heat generated from the LED.

The employmentof HTTM technology allows to transfer the heat generated from led towards the external lighter wall, maintaining low the temperature level inside the lighter and concurring to lengthen the lighter average life and its reliability.

Mechanical Mountig

It is recommended to install the lighter in a way that the inferior wall is in direct contact with a flat metal surface.

In this way the supporting surface of the lighter will be able to ensure a proper heat dissipation produced from LED.

PRECAUTIONS AND IMPORTANT NOTICES FOR THE PROTECTION OF GOODS AND PEOPLE

Employment of LED lighter in artificial vision systems

Why spend hundred of Euro for a LED lighting system?

Is not sufficient one economic light bulb buyable in whichever supermarket ?

Does it not carry out the same function ?

These are the questions that often place who for the first time acquires a LED lighter for artificial vision systems.

Then carefully analyzing the LED lighter features we notice that the obtainable performances with this type of luminous source are difficulty reached from many other luminous sources. Moreover it is always necessary to know that the lighting system performances, in an artificial vision system, constitute a good 50% of the system global performances and that the employment of expensive and sophisticated cameras and frame grabber cannot replace that that a good lighter can realize.

The main advantages offers from the LED lighters are :

- Possibility to choose the wavelength .....
It's possible to choose between different wavelengths and therefore between different colours of the emitted light (red, orange, amber, yellow, green, blue, violet, white, infrared). All emitted light colours, with the exception of white, are monochromatics.

- Long average life.
The average life of a LED source at semiconductor, correctly fed and operating at temperature inside the admitted limit, exceed abundantly the 100.000 hours.Moreover it maintains constant the own luminous intensity for a period estimated of 50.000 hours of working. During the remaining operating life, more than 50.000 hours, the LED undergoes a light and graduates redction of the emitted luminous intensity. In the greater part of the applications this light reduction of the emitted luminous intensity doesn't provoke any variation of the system behaviour.

- Good performances/cost ratio.
The LED lighter totally has a good performances/cost ratio determined from its long average life of working and from the stability of its luminous emission.

- Working at low tension.
With the exception of other luminous sources (for ex. fluorescent sources) the LED lighter works with an operating tension of few volt. This allow the installation of this type of lighter without particular precautions or dangers for the user.

- Easiness of personalization.
The LED is constituted from one small junction of semiconductor material realized on a substrate that is not larger than 1 mm². This particularity renders the LED easily integrable in lighters with the most varied shapes and dimensions, obtaining therefore personalized lighting systems.

- Sturdness and resistant to the vibrations.
The LED lighters just because constituted from luminous sources at semiconductor inserted in a seal container, are sturdy and adapted for installations with vibrations and mechanical shocks.

- Possibility to realize directional light beams at high intensity
Some LED lighter can be supplied in container with integrated lenses and therefore with a determined output angle. Joining more LED sources on an only support is possible to obtain light beams with output angles very precise and therefore easily directionables on the object to analyze. Is moreover possible to obtain light spot at high intensity by converging more luminous sources in the same point.

- Modulation possibility and luminous intensity regulation
The LED lighters allow the emitted luminous intensity regulation. Through special drivers is possible to vary the tension or the feeding current of the LED matrix by consenting the emitted light quantity variation from the lighter. If the tension or current variation is not gradual but is instantaneously passes from 0% up to 100%, or vice versa,is possible to obtain the controlled lighter turn on and turn off . in this case is possible to turn on and turn off the lighter with an external drive, by generating light flash of extremely short duration, also in the order of 1 millionth of second (1 us). The limitation of the emitted light, both reducing the emission level of the single LED, and turning on the lighter only when necessary and turning off when the vision system is not operating, allows further lighter average life lengthening and a lowering of the medium temperature of working.

- Possibility to obtain brilliant light beams for short periods.
It is possible to obtain through special drivers a luminous emission also 5 times more intense than that nominal for short time periods without compromise the lighter duration. This technique must be carried out with special power supplies (driver) purposely realized for this type of employment.

The main disadvantages deriving from the LED lighter employment are:

- High working temperature if they work in way "always ON".
If the lighter is employed in way "always ON" it can establish an high working temperature that could accelerate the LED source decline process and therefore a reduction of the light average life.
If there wasn't the possibility to employ the lighter in modular way, we suggest the installation in places where there's an adapted produced developed heat (through the equipment chassis or through external wasters) or in presence of eventual cooling fans. We moreover suggest that never set the lighter near heat sources or near warm elements.

- Homogeneity of the emitted light not always comparable with other types of luminous sources.
For the emission intrinsic feature of the LED (punctiform light source) in some applications where is demanded a very high luminous emission homogeneity, the light emitted from the LED lighters could be not comparable with the homogeneity of some others types of lighters.
