Thorlabs also offers a range of unmounted, mounted, collimated, and fiber-coupled LEDs that are designed for a variety of applications, including microscopy, illumination, and measurements. For questions on choosing an appropriate LED and to discuss mounting requirements, please contact Tech Support.

White Light LEDsThis illuminator is a daylight white LED ring featuring a broad spectrum that spans several hundred nanometers; see Table 1.1 for a typical output spectrum. It has a correlated color temperature 5500 K, which indicates that the color appearance is similar to a black body radiator at the same temperature. In general, warm white LEDs offer a spectrum similar to a tungsten source, while cold white LEDs have a stronger blue component to the spectrum; daylight white LEDs provide a more even illumination spectrum over the visible range than warm white or cold white LEDs. To discuss LED ring lights with other correlated color temperatures or nominal wavelengths, please contact Tech Support.

Constructed from anodized aluminum, this LED ring light housing features four 4-40 tapped holes that are compatible with our Ø6 mm ER cage rods, allowing for integration with 30 mm cage systems. The housing also features three setscrews on the sides for interfacing with various camera lenses and high-magnification zoom lens systems (as seen in Figure 1.4), which can be secured using a 5/64" (2.0 mm) hex key or balldriver. An M60 x 1.0 external thread at the head of the ring light gives the option of attaching various elements such as custom filters or diffusers.

Use our lux/lumens calculator to determine how much light is needed for your industrial lighting application.

Hideaway strobe lights are small and concealed warning lights that are designed to fit inside the already installed lenses of emergency vehicles.

For convenient connection to the drivers listed below and on the LED Drivers tab, the LED ring light has a connection cable with an M8 connector; see the Pin Diagram tab for the M8 connector pin information. This LED ring light also features an EEPROM chip which stores information about the LED (e.g., current limit, forward voltage). When controlled by a Thorlabs UPLED, DC40, or DC2200 LED driver, this data can be used to implement smart safety features.

Figure 2.1 shows the male connector of the LEDRW40 Ring Light. It is a standard M8 x 1 sensor circular connector. Pins 1 and 2 are the connection to the LED. Pin 3 and 4 are used for the internal EEPROM. If using an LED driver that was not purchased from Thorlabs, be careful that the appropriate connections are made to Pin 1 and Pin 2 and that you do not attempt to drive the LED through the EEPROM pins.

Driver OptionsThorlabs offers four drivers compatible with this LED ring light: LEDD1B, DC40, UPLED, and DC2200. See the LED Drivers tab for compatibility information and a list of specifications. The UPLED, DC40, and DC2200 drivers are capable of reading the current limit from the EEPROM chip of the connected LED ring light and automatically adjusting the maximum current setting to protect the LEDs. The DC40 LED driver can provide drive currents with up to a 5 kHz modulation when supplied with an external modulation signal. While the DC2200 driver is capable of modulating frequencies up to 250 kHz, the LED ring light must not be modulated at or above 9 kHz.

Tunable white lights can adjust to a wide range of color temperatures, from warm to cool, independent of the brightness level. Dim-to-warm lights, however, ...

To fully support the max optical power of the LED you intend to drive, ensure that the max voltage and max current of the driver are equal to or greater than those of the LED.

The EZ light is a floodlight with an illumination span up to 5ft wide. The universal clamp is designed for tubular displays with poles less than 2" in diameter.

Thorlabs' LED Ring Light Source consists of 40 individual broadband, daylight white LEDs in a ring-shaped array with a Ø0.99" (Ø25.1 mm) clear aperture. By angling the LEDs, this ring light illuminates areas from 50 mm to 300 mm along the emission axis that can then be viewed through the clear aperture, making it ideal for machine vision applications.
