VRL-74 LED RANGE LIGHT The VRL-74 has a single LED operating through a high power optical grade acrylic lens having a 3° divergence on the horizontal and vertical plane. Divergence is defi ned as the angle where the intensity is at 50% of the centre intensity of the lens. Profi le of the VRL-74 lens shows a wide angle of centre intensity and a sharp cut of at higher angles. High intensity makes the VRL-74 lens suitable for use as a lead or range light. The sharp cut off at the higher angles allows the lens to be used for high range sector light applications with the angle of uncertainty between colours of approximately 0.5°. The versatility of the VRL-74 lens has provided three distinct product groupings: 1. The Mini Array is the standard product offering of the VRL-74 and consists of mounted lenses on a vertical plane. The product is available from 1 to 6 lenses depending on the requirement for intensity and divergence. The Mini Array application is intended for range or lead lights. 2. The Mini Solo product consists of single VRL-74 lenses that are arranged to meet a specific application requirement. As such the product is customised to the application. The Mini Solo product is used where wider divergence is required compared to the Mini Array including high range multicolour sector lights. The Mini Solo is also used to configure signals such as arrows or crosses to indicate safe navigation channels. 3. The Mini Tile product is a larger form of the Mini Array and contains a higher number of VRL-74 lenses. This is provided where higher intensity range or lead lights are required. The Mini Tile layout is customised to each application. The maximum intensity and current at 12VDC for a fi xed character using the standard VRL-74 3° lens is as follows: Colour Max Intensity Candela x1000 Current mA @ 12VDC White 80 450 Red 22.1 115 Green 37.5 390 Yellow 8.5 65 Blue 13.6 345 Spreader Lenses can be fi tted over the VRL-74 Lens to increase either or both the vertical and horizontal divergence. The spreader lenses are available in standard formats, however with the fl exibility of 3 dimensional machining custom spreaders can be made for any application. Spreader code Horizontal divergence when fitted Vertical divergence when fitted Intensity multiplier 21 6 3 2 22 6 6 4 31 9 3 3 32 9 6 6 33 9 9 9 41 12 3 4 42 12 6 8 43 12 9 12 51 15 3 5 52 15 6 10 53 15 9 15 61 18 3 6 62 18 6 12 63 18 9 18 When a spreader lens is fi tted, the multiplier of the spreader reduces the intensity of the assembly. The intensity with a spreader lens fi tted is the intensity of the base VRL-74 lens divided by the multiplier. Spreader lenses can be rotated by 90° to provide greater fl exibility of horizontal and vertical divergence. INFORMATION REQUIRED Vega has a questionnaire available to assist with the collection of the necessary information to defi ne the requirements of a Range Light or other form of VRL-74 application. A copy of this can be obtained by contacting sales@vega.co.nz The required information includes 1. Range required for both day and night 2. Flash character and colour 3. Horizontal and vertical divergence required 4. Details of the application including channel length and width 5. Details of size of vessels using the light VRL-74 MINI ARRAY The Mini Array is available in 6 formats from 1 to 6 lenses. Spreader lenses can be added to increase the vertical and horizontal divergence of the light. It is possible to use different spreader lenses in order to provide the best outcome for an application such as fi lling in the intensity at the near end of a channel. This an area that may not be illuminated using normal range lights due to the narrowing of the beam closer to the light. The maximum intensity without spreader lenses fi tted is as follows. Lenses White Red CD x1000 mA CD x1000 mA 1 80 450 22.1 115 2 160 900 44.2 230 3 240 1350 66.3 345 4 320 1800 88.4 460 5 400 2250 110.5 575 6 480 2700 132.6 690 Lenses Green Yellow Blue CD x1000 mA CD x1000 mA x1000 CD 1 37.5 390 8.5 65 13.6 345 2 75.4 780 TBA TBA 27.6 685 3 113.1 1170 TBA TBA 40.8 1030 4 150.8 1560 TBA TBA 54.5 1375 5 188.3 1950 TBA TBA 68.1 1720 6 226.2 2340 TBA TBA 81.6 2060 Where spreaders are fitted the intensity will be reduced by the spreader multiplier. Note that spreader lenses are different for each colour and cannot be swapped between colours. Operation of the Mini Array The Mini Array is programmed as a single unit and can operate day only, day and night, or night only. Day and night intensity is separately programmable. The minimum night intensity is approximately 3% of the maximum intensity of the VRL-74 Mini Array assembly. The controller for the lights is part of the integrated assembly. The VRL-74 Mini Array contains the programmable features that are normally found in Vega Beacons. Mounting of the Mini Array Horizontal mounting is the standard option however vertical mounting is available if advised at time of order. The Mini Array is adjustable in both the horizontal and vertical planes for fi nal alignment to the navigation channel. Alignment tools are available as an option should precise alignment be required. These consist of either a gun sight or a telescopic sight mount (Vega does not supply the telescopic sight). These alignment tools are detachable and one can be used to align many Mini Array units. Additional Options • Internal GPS for pulse synchronisation with other lights • Alarm/Monitor Output
EASY PROGRAMMING The VRL-74 supports the standard features found on Vega marine LED beacons. • Automatic Schmidt-Clausen intensity correction for short flashes • Multiple effective intensity settings for both day and night operation • Day/night transition level settings • Programmable flash characters • One programmable custom character • Synchronisation control including master/slave options and sync delay • Programmable low voltage cut out • Optional security code • Read supply voltage • Serial number, LED type etc, are stored in the range light Programming is done using the Vega TVIR Programmer (Remote-02). This allows the range light to be programmed one feature at a time. The VRL-74 will confi rm the settings by fl ashing the programming code back to the user. Monitoring Monitoring of the VRL-74 LED Range Light can be provided in a number of ways: 1. Using the Vega Mini VegaWeb internet monitoring unit. 2. Using the optional alarm/monitor connection.
