  • LED Group Customised Conversions

Customised Conversions

Light-fitting conversions to meet your individual project requirements.

We take standard light fittings and add modifications that enhance their functionality. Everything from converting a standard fitting into emergency, sensor or dimming options; enhancing energy savings or modifying a product to reduce labour and installation time.

What is Emergency Lighting?

An emergency light is a lighting device with a battery pack that switches on automatically when a power cut occurs.

Learn more

An emergency fitting’s battery pack is required to power the light fitting for a minimum of 3 hours. To maintain power, the light output from the emergency light fitting is reduced in comparison to regular light output.

Maintained fittings operate and are controlled as normal light fittings with all the other light fittings in the area. When power fails however, the maintained emergency light fitting continues to operate at a reduced light output.

Non-maintained fittings are usually switched off, with their batteries being continuously charged and a green LED showing fully charged. When power fails, non-maintained fittings switch on using the battery power supply. Non-maintained emergency fittings are not part of the general lighting but are more specific functional lighting. Non-maintained fittings can be completed by special request.

Light Levels During an Emergency:

Open Areas
The safest, quickest escape route without obstruction should be lit to a minimum of 1 lux during an emergency. Should the open area be less than 60m2 and is not part of an escape route then emergency lighting is not required. However, the exit doors for the emergency escape route must have signs or an emergency bulkhead.

Designated Corridors
An escape route should not be obstructed and lit to a minimum of 1 lux during an emergency.

Stairwells
Stairwells have increased hazards therefore these areas should be lit to a minimum of 2 lux during an emergency.

Types of Dimming Control Protocols

Selecting the proper dimmer was once a simple task with a few choices for your home or business lighting systems. With all the changes over recent years, selecting the proper dimmer now has many new considerations such as; type of lighting, wattage load, single/multi-location and style. Dimmer Control Protocols are the method of transmitting information to the light fittings.

Emergency Options

Emergency
Operates for a minimum of 3 hours during power failure.

Self-test Emergency
Initial function and duration tests are randomly generated. This reduces the cost of manual testing.

Dali Addressable Emergency
Once a DALI command is received, fittings enter DALI mode and will perform functional and duration tests.

Switch Dimming

Learn more

With Switch Dimming it is possible to create lighting systems that can be easily switched and dimmed at low cost. It involves using standard mains retractable switch for lighting controls.

The different switching and dimming functions are performed depending on the operating status at the time and how long the switch is pressed.

A short press on the switch, switches the connected driver to turn the fitting on or off.

A long press on the switch will dim the connected driver up or down depending on its current operating status.

Analogue Dimming - 1-10V Method of Control

Learn more

Analogue Dimming

Analogue dimming uses a separate control wire to notify the driver that the power of the LEDs should be changed. The separated control signal is a DC (direct current) and can be adjusted from 1 up to 10 volts, the voltage level is interpreted by the driver to set the LED power.

1-10V Method of Control

The 1-10V method of control is a low current system (typically 1mA) meaning it can be run along relatively thin cables with little voltage drop and depending on dimmer manufacturer recommendations. This allows for up to 50 LED dimmable drivers on one wall mounted dimmer.

DALI Dimmable

Learn more

GRID - What is Digital Addressable Lighting Interface?

It is a testing and control system, programmed by the DALI controller/system. The fitting will enter a self-commissioning phase; DALI Units also offer status feedback reports to the system. Once the module has received a valid DALI command, the module enters DALI mode and adopts default settings for test pre-programmed.

DALI Control System

DALI is a digital communications protocol that was developed for the lighting industry. A separate control wire of BUS is used to send digital information to light fittings and allows the individual light fittings and sensors to communicate with an advanced lighting control system. Although DALI is a standard protocol beware of mixing components between manufacturers with our testing first. Along with the correct LED Driver the DALI system requires additional control equipment including DALI BUS controllers, power supplies, sensors and user interfaces.

Conversions to Reduce Labour & Installation Time

15W ROBUS GOLF LED Case Study

View our step by step guide

When a project requires installation of hundreds of fittings and the contractor would like to reduce the installation time to complete the project in a shorter time frame, we are asked to perform the following conversion.

The example below is a step by step guide converting a 15W ROBUS GOLF LED (R150LED-01) into a 15W ROBUS GOLF LED with SWIFT CONNECTOR (R150LED-01WC).

The benefits of a conversion like this are:

• Cost Saving
• Time/Labour cost reduction
• Ease of replacing lamp  
• No need to turn off the power which means a day to day operation can still run smoothly
