[0002] Engineering lighting devices are designed to provide high-intensity, stable lighting for outdoor or semi-enclosed work environments, such as construction sites, road maintenance, tunnel operations, building sites, mining areas, and ports. Their primary function is to provide sufficient illumination to ensure safe and efficient work at night or in low-light environments (such as tunnels, underground projects, and nighttime construction). They are ideal for large construction sites requiring high-brightness, wide-coverage lighting.

[0003] Existing engineering lighting fixtures typically use a fixed brightness design and are unable to automatically adjust brightness based on ambient light fluctuations, resulting in energy waste or insufficient lighting. Furthermore, dust often accumulates in engineering environments, easily covering the lamp housings and further reducing lighting effectiveness. While some lighting fixtures have dimming functions, they lack monitoring and automated cleaning capabilities to detect dust impacts. Over time, dust accumulation can affect the accuracy of light sensors. Therefore, there is an urgent need for engineering lighting fixtures that can automatically adjust brightness and have self-cleaning capabilities. Summary of the Invention

The microcontroller 6 automatically controls the self-cleaning mechanism to clean the mask of the lamp 2 to prevent dust from affecting the brightness. After preventing dust from affecting the brightness, the microcontroller 6 controls the lamp 2 to emit a higher brightness to save energy.
