A Roobuck Intrinsically Safe LED Strap Light is the World¡¯s First Product of its kind. It is a flexible portable light and can be attached to your body and mounted on the wall or equipment. The light source of a LED Strap is a LED Bar Chain which includes a single or multiple soft LED Bar which is connected by a cable or cables. There are several types of LED Bars, including 2, 3, 4, 15 or 32 LEDs for different applications.
The light source is powered by a waterproof Battery Box, connected to the light source through a waterproof connector. A Battery Box can be put in your pocket or specially designed for a Battery Box porch. There are two types of Battery Boxes containing 2xAA replaceable alkaline batteries or a rechargeable lithium battery.

 

With Roobuck Battery Box, LED Bars, and waterproof connectors and cables you can implement various configurations for different products and applications. Roobuck ¡°High Visibility LED Vest¡± and ¡°Cloth Light¡± are typical examples. Roobuck welcomes workwear manufacturers or other organizations to create your own products using our I.S. LED Straps. There are two types of LED Straps for signaling and light respectively.

LED Lighting Strap

(Model RLS-LBW-Ex, under IECEx certification)

 

A LED Lighting Strap uses white LEDs and the Lithium Battery Box. It is a flexible light for close field illumination. The model is RLS-LBW-Ex in different LED Bar configurations.
A typical application is a Cloth Light. A Cloth Light includes two 15-LED Bars attached to the front of the cloth and connected with a cable. One LED Bar is on the left and another one is on the right.
The Battery Box is placed in the specially designed Battery Box porch or hooked onto the belt using a Battery Box Bracket.
A Cloth Light also can include two LED Bars in red for warning as an optional feature. Warning bars are attached on the back ¨C one on the left and another one on the right.

Operation

There are three Operating Modes generating different LED signaling. By using the operating button on the Battery Box, the LEDs go through Stable-On mode, Slow-Flashing mode and Fast-Flashing mode. It always starts up from the Stable-On mode when switched on.

The Battery Box can be opened by unscrewing the bolt on the Battery Box. To keep the IECEx Certificate valid, you can only use the following AA batteries:
-- Energizer. Model: Max91
-- Duracell. Model: Coppertop MN1500
-- Varta. Model: High Energy 4106

Specifications
Operating period (default): 3 hours for High Level or 12 hours for Standard Level
Battery capacity: 3AH Battery Box weight: 90g
Ingress protection: IP65 Ambient temperature: -20oC ~ +40oC
LED Signalling Strap
(Example model RLS-ABR-Ex, IECEx certified)

LEDs of a LED Signaling Strap can be in any color, although most of them are in red/orange. The Battery Box can be either Alkaline or Lithium. It can be used to highlight a person, an equipment or a place to increase visibility in a dark environment.

The most popular model is RLS-ABR-Ex, using the Alkaline Battery Box and red LEDs. Its typical application is a high visibility (Hi-Vis) workwear. A Hi-Vis product can only reflect incoming light. If the LED Strap is attached to the Hi-Vis workwear, it will actively generate a signal in a completely dark environment. It also can be used to make a simple wearable product such as LED belt, LED strap and LED harness.
LED Strap Worn by miner

This LED Strap is certified in IECEx as ¡°Ex ia¡± for zone 0 applications in Group I for underground coal mines and Group IIB T3 for petrochemical environments.

Operation
There are three Operating Modes generating different LED signaling. By toggling the operating button on the Battery Box, the LEDs go through Stable-On mode, Slow-Flashing mode and Fast-Flashing mode. It always starts up from the Stable-On mode when switched on.
The Battery Box can be opened by unscrewing the bolt on the Battery Box. To keep the IECEx certificate valid, you can only use following AA batteries:

I.S. LED Line

(Models RLS-ALR-Ex or RLS-LLR-Ex, IECEx certified)

A LED Line is a special version of a LED Strap. The key difference is that all LEDs are in 360 degree directions. This makes it suitable for site warning where signals in all directions are required.
Comparing to a standard LED Strap, a LED Line is also much thinner in less weight and lower cost. Therefore, it is also suitable for a low cost LED Signaling Strap.
Model numbers of LED Lines are RLS-ALR-Ex for Alkaline Battery Box model and RLS-LBR-Ex for Lithium Battery Box mode.

Model numbers of LED Lines are RLS-ALR-Ex for Alkaline Battery Box model and RLS-LBR-Ex for Lithium Battery Box model.
