New Aviation Warning Light Signals The Way

Posted on by

Product development is what drives businesses such as D. G. Controls Ltd forward, and having our own full-time development engineer based at our UK office gives us a reactivity second to none when it comes to developing products to customers’ requirements. 

Recognising our position in the aircraft warning sector, orders are now in from our key distributors for the newest in the range, the SBB LED 10 Candela Aircraft Warning beacon.  Officially termed the SBB/*/*/LED/Type A/Red, this little beacon meets the ICAO regulations for low level intensity warning of aircraft.  Being a 360 degree viewing enclosure, the SBB Type A uses different LEDs from the larger SBE and SBG Type A products, offering a higher light intensity per LED, and meaning that the required brightness levels are met within the much smaller series B enclosure.

Series B is an IP65 rated enclosure, pre-moulded with M10 and M20 cable gland entries.  The lens fits with a specially designed O-ring and tightens on a bayonet-style fitting, securing with a tamper screw  into a blind hole.  Carefully designed to minimise dust and dirt build-up, and fully water-tight, Series B is perfectly suited to the outdoor environment, and with long-life LEDs, makes maintenance a thing of the past.

High intensity LED beacon for office use

Posted on by

Using the low profile Series R enclosure from the deegee brand, PSR/*/*/LED-FIRE is a high-intensity, low-current L.E.D. warning beacon ideal for use with fire-alarm systems. Using high-intensity L.E.Ds. the beacon can achieve an effective luminous intensity of up to 115 Candela.

With a standard beacon flash rate of 60 flashes per minute, one of two synchronising modes (/SYNC) can be selected at time of installation using a jumper link.

In /SYNC mode 1 the units are connected in a network (output of beacon 1 to input of beacon 2 and so on) and all beacons will synchronise to beacon 1. In /SYNC mode 2 all beacons respond to a 5mS break in the power supply. This makes PSR/*/*/LED-FIRE perfect for use either individually or in a run for instance down a corridor, where synchronisation is essential to reduce stress on individuals during an emergency.

The systems designer can ensure that the unit is operated with maximum energy efficiency by selecting one of four brightness modes most appropriate to the application – 45Cd, 60Cd, 75Cd or 115Cd (default setting) – by way of two on-board jumper links. 

The Series R enclosure is perfect for public and office installation.

EuroLED 2008

Whilst preparing for this year’s EuroLED show, 4th-5th June 2008, I fell over a video summarizing last year’s event.  Of particular interest to us is the number of times that our products were shown.  This is confirmation that our range is indeed innovative and of interest to the wider electronics community.

The video is only around 3 minutes long so sit back and enjoy.

MIH Traffic Lights and SBU Single Colour units

Posted on by

Following a recent study at D. G. Controls Ltd, the LED version of the MIH Traffic Light and the SBU Single Colour Unit has been upgraded by fitting a plain polished lens plate, in preference to the ribbed lens previously fitted.

Given the application of the unit, and it’s directional characteristics, the new lens was trialled to establish whether this focussed more of the light in the forward direction than the ribbed lens was achieving.  Whilst already a high light output unit, just by changing the lensing the measured output increased by a further 700%.

Firmly established as a top-seller in the deegee portfolio, the SBU/LED, and the MIH/2U/LED and MIH/3U/LED are used in a wide range of indoor and outdoor applications.  Being ingress protected to IP65, and moulded from a robust polycarbonate, they offer an ideal solution where larger multi-status indication is required.

Multi-Function (MFE) LED Beacons

Posted on by

Multi-status indication from the same beacon is sometimes necessary due to restrictions on space.  deegee has long had in its portfolio the MFE multi-function beacon, an LED beacon which has 360º viewing. 

A single MFE LED beacon can give 8 different warning signals, switchable externally.  Offering pulsed, wig-wag and chasing patterns, in several styles and flash rates, these beacons are well-suited to applications where low current draw is essential, the AC version drawing just 26mA at 230V and 45mA at 115V.

Available as a dual-voltage 115/230V AC and 12/24V DC unit, and in colours red, amber, green, blue and clear, the MFE is extremely versatile.  The ABS base with polycarbonate lens is rated to IEC Protection Class IP65, making MFE equally effective in indoor, outdoor and dusty environments.
