Projectors equipped with a Fresnel lens, recognizable by the particular surface with concentric “steps” which allow a wide and uniform diffusion of the light beam, making the transition between the light and shadow areas very soft.

This type of fixture, equipped with an adjustable fork and optics adjustment system, is used to obtain diffused and uniform directional lighting, with particularly soft “out-of-focus” contours.

The fixture is able to emulate the performance of a halogen lamp.

In the continuous search to satisfy “nostalgic” light designers of halogen light and to get closer to the natural perception that the human eye has of an object illuminated with LED, it is not enough that the static light simulates halogen light, but that it is also dynamic regulation. For a LED luminaire to behave like a halogen headlight, there are three aspects to consider:

– the dimmer curve which represents the inertia with which the light is returned by the source according to the signal it receives. It can be set up as linear or quadratic with “slow release” curvature.

– the delay, i.e. the “delay” with which a filament begins to emit light after it receives the electrical stimulus. Shift the curve by milliseconds, adjustable.

– the amber shift effect, it is a “defect” or imperfection typical of the halogen lamp which allows a slight amber/orange color change to which a halogen lamp tends when it is dimmed down, reducing its emission.

ABLE TO ELIMINATE VISUAL AND ACOUSTIC DISTURBANCES

The fixture is able to resolve or minimize the main disturbances.

Silent mode – in order to work properly, a lighthouse needs a cooling system, which can be passive (radiator type) or active (presence of fans that “blow” the hot air away to make the source work within a range temperature considered ideal). The silent mode function allows you to intervene on the speed and therefore on the noise of these fans: an algorithm detects the internal temperatures from the thermostat and controls the current to ensure continuous operation of the light, preventing damage or shutdowns. In some situations, for example in the lighting park above the symphony orchestra or in some art museums, “absolute silence” is required, therefore it is necessary to be able to deactivate the operation of the fans.

Flicker free – when filming a show with cameras or even simply with the smartphone video camera it is possible that annoying oscillations (flickering) appear on the screen due to the frequency conflict between the emission of the LED light and the scanning of the brush of the receiving camera. This conflict must be resolved by acting on the camera recording parameters or on the LED source parameters.fixture

Booster – this is a function that allows the light emission of the individual channels to be increased up to +20%, when a tint or a CCT value is selected in which not all channels are at full.

A microprocessor monitors the working temperature of the LED and updates the source control parameters in real time.

ABLE TO OPERATE WITHOUT CONSOLE

Stand alone – this funciotn allows to control one or more fixtures without using a console. In fact, the software allows you to create one or more static colors and to define the duration and sequence of each one.

The function can be set on a single fixture or on a group of fixtures. In this second case it is necessary to define the “master” fixture and the “slave” ones.

In white versions, it is possible to choose from the following color temperatures:

WW version: 3’000K

CW version: 5’600K
