To make a high-output LED light, first, the high-intensity LEDs are positioned in a highly dense, staggered arrangement. Furthermore, by using conical reflectors, it is possible to make use of the entirety of the light generated by the LEDs. This enables high-intensity lighting with long LWD, which was difficult with conventional LED lights. Also, a mirror surface finish is applied to the entirety of the lighting area, which enables effective use of even the illumination that is returned to the inside of the light by the protective cover or diffusion plate. When not using a diffusion plate, light with sufficient brightness can be emitted even with an LWD of 3000 mm.*
* Check in advance whether the light intensity is sufficient for the actual usage environment.
Attaching the included diffusion plate to the light makes it possible to use the product as a high-intensity illumination light not only with a long LWD but at a short distance from the target as well. Selecting an optional polarising diffusion plate makes it possible to use the light even with workpieces such as those that are glossy. The ability to use a diffusion plate or polarising diffusion plate with a high-output LED light is an industry first.
The diffusion plate and polarising diffusion plate have simple constructions such that they snap onto the light, which eliminates any concerns of screws falling down onto the line.
Even when lighting cannot be installed within the movement range of the robot, a wide area can be lit with sufficient brightness.
Even for large cardboard boxes, the wide illuminated range enables stable detections for both marking inspections and inspections for the mixing of different types of products.
A polarising plate is pasted to the diffusion plate to ensure even polarisation.
The above image displays the relative brightness across a multiple point grid for the CA-DB Series. Although the intensity varies with each model type, the associated illumination distance and relative brightness across the area are consistent. The brightest areas (shown in red) are considered 100% relative intensity and the dullest areas (shown in green) are considered 0% relative intensity. The images display the intensity differential across the area. By comparing the changes in the intensity differential for different degrees of diffusion, the ideal lighting range can be realised with the relative brightest points being 100%.

* LWD is the distance from the illumination to the measurement target.
