Page 12: Photobiological Safety
LTSP | USER MANUAL 3.4 Photobiological safety LTSP series has been tested against EN 62471:2008 (photobiological safety of lamps and lamp system). The norm classiﬁes LED lightings in 4 distinct groups, according to their hazardousness degree. For LTSP series, the risk group is reported in Table 5.
Page 13: Getting Started
LTSP | USER MANUAL 4 GETTING STARTED 4.1 Overview LTSP products are high power LED spotlights with integrated electronics. LTSP LED spotlights are designed to operate in both continuous and pulsed mode with an easy hardware interface. Also the boosted mode is allowed, which offers the possibility to have in- creased continuous power delivered for a time duration up to 4.2 Accessories As schematized in Table...

LTSP | USER MANUAL 5.2 Connectors and pinout The M12 straight plug male connector is schematized in Figure in order to show the pins. The functionality of the pins are shown in Table 9. Figure 5: Scheme of the connector pinout (device side). Standard Power + Analog dimming...
Page 17: Electrical Specifications
LTSP | USER MANUAL 5.3 Electrical speciﬁcations The voltage supported by the pins in Figure for the standard variant device are: Voltage 1: Power V (Maximum Working voltage) V (Absolute Maximum Ratings) 2: NPN V (Absolute Maximum Ratings) 3: GND Ground 4: PNP V (Absolute Maximum Ratings)
Page 18: Operating Modes
LTSP | USER MANUAL 5.6 Operating modes The LEDs can operate in three different modes: the continuous mode, the boosted mode and the strobe mode that are schematized in Figure and described more precisely in the following sec- tions. Figure 6: LED power delivered in the three modalities. The time scale of the strobe mode is different from the other ones.
Page 19: Continuous Mode
LTSP | USER MANUAL 5.6.1 Continuous mode Continuous operations are available with the possibility of delivering continuous electrical power on the LED. In order to select the -continuous mode, there are two different options: 100% 1. the pin NPN must be kept at N P N 2.
Page 20: Boosted Mode
LTSP | USER MANUAL 5.6.2 Boosted mode In boosted mode, the LEDs are allowed to be slightly overpowered compared to the continuous mode ( of the power), forcing a use with shutdown after a time interval on the order of 200% 30 60 s to avoid excessive overheating of the device.
Page 21: Strobe Mode
LTSP | USER MANUAL 5.6.3 Strobe mode Operations in strobe mode are available with the possibility of delivering pulsed electrical power on the LEDs (about % of peak power with respect to the continuous mode power). When V or V, the LEDs are turned on for a time duration that corresponds to >...

Page 24: Analog Regulation Use
LTSP | USER MANUAL 5.6.5 Analog regulation use The electrical power delivered on the LED in continuous mode can be regulated with power mod- ulation by means of the connection of the Pin 5 (analog input) to an input voltage 100% V, without using the PNP and NPN input signals.

Page 33 LTSP | USER MANUAL Appendix B The images of the beam transverse sections at different working distances, as well as the intensity proﬁles Gaussian ﬁt, allow one to verify how the degree of spatial homogeneity and the spot size vary with distances. For the estimation of the spot size it is possible to consider the quantity that is the radial distance in the transverse plane at a speciﬁc working distance within which the of the total spot energy is contained.
