POMEAS Dome Light Source, as a highly efficient diffuse reflection shadowless light source, has a carefully designed structure to ensure that the light is smoothly and uniformly illuminated on the surface of the object under test after diffuse reflection from the sphere. Its optimized LED arrangement and unique structural design give it a large light diffusion surface, which achieves an all-around uniform illumination of the object under test.

Light source structure： 

Spherical Integral Diffuse Surface: This is the core part of the dome light source, which utilizes the characteristics of the spherical surface to diffuse the light emitted by the LEDs evenly and softly, thus avoiding shadows due to undulations or reflections on the surface of the object, and ensuring the uniformity and stability of the irradiation.

PCB substrate: PCB (Printed Circuit Board) substrate is the carrier platform of LED, which is responsible for transferring electrical energy to LED, and at the same time to ensure the stability and reliability of the electrical connection between the LED.

Aluminum alloy shell: Aluminum alloy shell not only provides solid protection for the light source, but also has good heat dissipation performance, to ensure that the light source in the high-intensity work can be stable operation.

Thermally conductive silicone: Thermally conductive silicone is used between the PCB substrate and the aluminum alloy shell, which can effectively transfer the heat generated by the LED to the aluminum alloy shell, and through the shell to the environment to ensure that the working temperature of the light source in the normal range.

Areas of application：

POMEAS dome light source is especially suitable for objects with undulating and reflective surfaces. For example, in the identification and detection of codes and characters on the bottom of cans, since the bottom of cans is usually made of metal and has a certain curvature, it is often difficult for traditional light sources to provide uniform irradiation, which can easily produce shadows or reflections, affecting the accuracy of identification. With its unique structure and excellent performance, POMEAS dome light source can evenly irradiate the bottom of cans, eliminating the effects of shadows and reflections and greatly improving the accuracy and stability of identification.

In addition, POMEAS dome light sources are widely used in a variety of applications where uniform illumination and high quality imaging are required, such as electronic component inspection, pharmaceutical packaging inspection, food packaging inspection and other fields.
