The BL-48 Ultraviolet Illuminator is a state of the art lighting instrument based on an array of 48
Ultraviolet LED's and a computer micro-controller. This unit permits ultraviolet effects to be faded
or strobed under DMX control. These effects cannot be created with other types of UV
illumination. The LED UV devices do not require replacement, produce little or no heat, and are
available in a range of dispersion angles and UV or near-UV wavelengths. From one to four
channels of DMX-512 data controls UV intensity, strobe rate, or other parameters as determined by
the LED configuration, and the settings of internal mode jumpers. The unit may also be operated in
manual mode without DMX as a stand-alone fixture with preset intensity and strobe timing if
desired. Illuminators may be controlled by any DMX lighting system for professional displays, or
may be set up for independent operation at a preset intensity or strobe rate in stand-alone UV
lighting applications.
A range of UV LED options are now available for installation in the unit. For replacing existing
fluorescent or incandescent UV light sources, 395 nanometer UV LED's may be installed to
duplicate the deep blue-violet output common to those fixtures. For pure ultraviolet displays, 385
nanometer LEDs, which produce very little visible light may be selected. UV LED sources of
different types, or with different dispersion angles may be installed in the same fixture, with each
LED type then controlled independently through DMX, providing unprecedented flexibility in an
ultraviolet fixture. All LED emissions are long wavelength UV-A light, which is not considered a
skin or an eye hazard
under normal conditions.

Summary of Contents for PPS BL-48
- Page 1 BL-48 DMX Ultraviolet Illuminator The BL-48 Ultraviolet Illuminator is a state of the art lighting instrument based on an array of 48 Ultraviolet LED's and a computer micro-controller. This unit permits ultraviolet effects to be faded or strobed under DMX control. These effects cannot be created with other types of UV illumination.
- Page 2 The unit may be mounted in any orientation. Product Compliance The BL-48 unit has been tested for compliance with the General and Particular Standards for Luminaires, under EN 60598-1 (2004), and EN 60598-2-1 (1989), and also for compliance with the Electromagnetic Compatibility (EMC) standards under EN 610000-6-3 (2001) and EN 610000-6-1 (2001), and are certified to comply with these standards.
- Page 3 CAUTION This product contains Ultraviolet Light Emitting Diodes (LED’s). During operation, the LED’s emit intense ultraviolet light. Precautions should be taken to avoid looking directly into the UV output for prolonged periods with the unaided eye, viewing the UV output at close range, or viewing through optical systems which enhance or concentrate the UV light.
- Page 4 CAUTION Connection of the unit to AC power sources, or to alternative power supplies other than the universal input DC power pack provided with the unit may r esult in damage to the unit. Do not attempt to operate the unit if you are unsure of the rating of the AC power source, or of the voltage and polarity of any alternative DC power supply.
- Page 5 DMX data source to determine what or where the problem is. Operational Mode Settings The BL-48 unit may be operated in any one of four modes as selected by internal programming jumpers. Power must be removed from the unit before opening the cover to change the mode jumper settings.
- Page 6 Operational Modes The mode selection corresponds with the number of consecutive DMX channels used in each mode, beginning from the base DMX address selected by the address switches. The DMX channel function and operation of the unit in each mode is listed in the following table. Mode Functions Manual...
- Page 7 Mode 1 Operation: Master Intensity on 1 DMX Channel Mode 1 is the simplest operational mode, using only a single DMX channel, corresponding to the base address selected by the three address switches. The data on that DMX channel will control the intensity of the output from the unit, with a zero level producing no output, and a maximum level of 255 producing maximum output from the unit.
- Page 8 Manual Mode Displays The manual mode displays are intended to provide the unit with a reasonable capability for demonstrating the properties of the unit, and are also useful for testing This capability may also be sufficient to complete simple effect installations where the cost or complexity of DMX controls are not necessary, but the benefits of a compact and very low maintenance UV source would be attractive.
- Page 9 Circuit Description The BL-48 Illuminator circuitry is most easily described as six sections, which are the power supply, the microcontroller, the DMX interface section, the address and mode selection section, the DAC or PWM output section, and the LED drivers and array. The microcontroller is the key element in the circuit, as the data ports on the device are assigned to all key circuit and interface functions.
- Page 10 These ports are commonly identified by letter designations, B, C, and D. In the BL-48 illuminator, the B port is used output data to the LED driver circuitry, and for device programming, the C port is used for device programming and to read DMX address settings, and the D port is to read address and mode settings, and for DMX input and sync indication.
- Page 11 Service Access The active electronics of the BL-48 illuminator are mounted on two circuit boards inside the main housing of the unit. These may be accessed by removing the four screws along the sides of the unit to open the main housing.
- Page 12 Remember that the unit loads DMX address data only when powered up, and power must be removed and restored before the unit will respond to a change in the DMX address or mode selector settings. If the settings are correct, but no display is observed, then the DMX control signal may be intermittant or low quality, or the unit may have an internal problem with the DMX address or mode selection circuitry, or with the LED display or driver circuits.
