MBJ SRL-04 LED Ringlight

MBJ-SRL-04-LED-Ringlight-product

Product Information

The MBJ Ringlight Series is a lighting system designed for indoor use only. It is available in four different sizes: SRL-04, SRL-07, SRL-10, and SRL-12. Each size has different outer luminous areas, with SRL-07 having an outer luminous area of 70mm. The lighting system is also available in six different LED colors: white, red, infrared, green, blue, and yellow. The exact peak wavelength of each LED color depends on the LED temperature and current.

The lighting system is equipped with 4 combined mounting positions of M5 threaded holes and M4 through holes, allowing it to be fixed to a specified position. To ensure a long lifespan, additional heat transfer measurements at the holding positions are highly recommended. The system is protected against ingress of solids and water in accordance with the selected protection class and applicable standards. However, permanent protection against liquids containing solvents cannot be guaranteed.

For electrical connection, the lighting system is equipped with a 4-pin M8x1 connector. Pin 3 is an active high input signal with 5-24V=ON and 0-1V=OFF, while Pin 2 is used as brightness control and operation mode switch.

Product Usage Instructions

Before working with the MBJ Ringlight Series, read the warning and application instructions carefully and completely before operating the device.

To use the lighting system, follow these steps:

Mount the lighting system to the desired position using the M5 threaded holes and M4 through holes.
Connect the lighting system to a power source using a 4-pin M8x1 connector. Use an MBJ lighting cable with a maximum length of 10m for best results.
Turn on the lighting system by connecting Pin 1 (brown wire) to 24VDC.
To adjust the brightness, connect Pin 2 (white wire) to a voltage source ranging from 1-10V.
To trigger the lighting system, connect Pin 3 (blue wire) to an active high input signal with 5-24V=ON and 0-1V=OFF.

For SRL-04, the -s controller is integrated into the cable. Supported operation modes with the integrated LED controller include steady light, steady light with brightness control, and triggered flash light with max. 20ms and up to 100% more light intensity. Refer to the manual for detailed connection instructions.

Mechanical Integration

The light is equipped with 4 combined mounting positions of M5 threaded holes and M4 through holes. It can be used to fix the lighting to the specified position. To secure a long live time additional heat transfer measurements at the holding positions are highly recommended.

Example: Model SRL-10

Specification	Ringlight Series
Operating temperature	10°C to 30°C / 45°C1)
Certifications	CE, RoHS
Degree of protection	IP54 or IP672)
Humidity	30 % to 70 %

Max. of 30°C is recommended for steady light operation w/o additional heat transfer measurements, for max. 45°C a thermal connection is mandatory. Max. of 45°C is also permissible for flashlight operation with a max. 10 % duty cycle.
MBJ LED lights are protected against the ingress of solids and water in accordance with the selected protection class and applicable standards. Permanent protection against liquids containing solvents, such as cleaning agents, machine emulsions or other lubricants, cannot be guaranteed. IP is only valid with a connected cable (MBJ cable recommended).

Safety Notes

Before working with this unit, read the warning and application instructions carefully and completely before operating the device.

The device is designed for indoor use only.
Light – Due to the risk of flash burn of the eyes it is not recommended to look directly into the light source. The lighting must be switched off before installation and/or maintenance. The device must not be used when a failure may cause a personal injury.
Heat – In case of insufficient heat dissipation or when running the light in flash mode with a too-high duty cycle, the surface temperature may exceed 60 °C. Keep off flammable materials at any time.
Electricity – The housing is electrically isolated from the ground of the power supply. Exceeding the permissible input voltage Uin or ULED(+) can lead to the destruction of the device or to a significant shortening of the lifetime of the LEDs in the device.
Usage – Please prevent mechanical stress to the light surface during operation. This will lead to an inhomogeneous light emission.
Cleaning – The light-emission surface has to be cleaned with a standard glass cleaner and a soft cleaning cloth. Do not use other materials for cleaning as it will damage the device.

Model Sizes in Series

The light is available in the following sizes 1)

SRL-04| SRL-07| SRL-10| SRL-12

Size definition: SRL-07 refers to an outer luminous area of 70 mm.

Possible LED Colors

LED	Abbr. 1)	Peak Wavelength 2)
White	-WT	5000 K, CRI80
Red	-RD	near 625 nm
Infrared	-IR	near 850 nm
Green	-GN	near 525 nm
Blue	-BE	near 465 nm
Yellow	-YE	near 580 nm

Color option will be added to the model name after the size information. Ringlight SRL-07-IR refers to a ringlight with 850 nm infrared light.
This is an approximated value. The exact value also depends on LED temperature and LED current.

Electrical Connection

The lighting is equipped with an 4 pin M8x1 connector.

Pin	Color 1)	Standard (-s)	Direct (-x) 2)
1	brown	24 VDC	LED (+)
2	white	Dim	LED (+)
3	blue	Trigger	LED (-)
4	black	Ground	LED (-)

Additional Information:

Pin 3 (Trigger) is an ‘active high’ input signal with 5…24 V=ON and 0…1 V=OFF, it is a high resistance current sink with 0.2 mA for 5 V and 5 mA for 24 V
Pin 2 (DIM) is used as brightness control and operation mode switch, it is a high resistance current sink with 0.2 mA for 5 V and 1 mA for 24 V.
For the connection it is recommended to use the MBJ lighting cable with a maximum length of 10 m.
SRL-04: due to the small size of this ring light the -s controller is integrated into the cable (cable controller).

Integrated Controller (-s)
Supported operation modes with the integrated LED controller

Pin 2 (Dim)	Operation mode
24 V	steady light 1)
1…10 V	steady light with brightness control 2)
24 V	triggered light
GND	triggered flash light with max. 20 ms and up to 100 % more light

intensity 3)

Pin 3 (Trigger) needs permanent 24 V to activate steady light mode.
PWM with 3.8 kHz clock is used, recommended minimal camera exposure is 5ms.
Latency between trigger and LED light ON is about 20…30 µs, the maximum recom-mended clock speed is 1 kHz, the maximum recommended duty cycle is 25 % and the minimum recommended flash time is 100 µs.
