Abstract
Description
Technical Field
[0001] This utility model relates to a workshop lighting and ventilation device. Background Technology
[0002] In the architectural design of industrial production workshops, lighting and ventilation are key factors in ensuring a comfortable production environment and improving operational efficiency. Current technologies typically incorporate skylights (such as fixed transparent skylights or skylight strips) in workshop roofs, primarily to supplement indoor lighting with natural light and reduce energy consumption for artificial lighting. However, traditional skylights often employ fixed structural designs, only fulfilling the function of lighting and failing to address the need for indoor-outdoor air circulation. When dust, waste heat, or harmful gases are generated within the workshop, relying on mechanical ventilation systems not only results in high energy consumption but also limited air exchange efficiency, making it difficult to meet the requirements of green production for natural ventilation.
[0003] If skylights are designed as openable structures (such as sliding windows or top-hung windows) to achieve ventilation, poor rain protection can easily occur. During rainy weather, open skylights can allow rainwater to enter the workshop, affecting the safe operation of production equipment and product quality. Therefore, existing workshop roof skylights generally suffer from the technical pain points of "separation of lighting and ventilation functions" and "difficulty in balancing ventilation and rain protection," urgently requiring an integrated solution that can combine lighting, natural ventilation, and reliable rain protection.

The upper rain shields and middle rain shields, and the middle rain shields and water collection tanks are staggered, and the overall horizontal projection surface of the upper rain shields, middle rain shields, and water collection tanks completely covers the ventilation opening, and the drain outlet of the water collection tank leads to the outer roof surface of the roof outside the ventilation opening.

Furthermore, there are drainage gaps between the left end of the water collection trough and the left side baffle, and between the right end of the water collection trough and the right side baffle, to facilitate water flowing down to the outer roof surface.
[0010] Preferably, the bottom edges of the front side barrier, rear side barrier, left side barrier, and right side barrier are all located below the top end face of the vent, and a flashing plate is provided between the front side barrier and the front side wall of the vent, between the rear side barrier and the rear side wall of the vent, between the left side barrier and the left side wall of the vent, and between the right side barrier and the right side wall of the vent.

[0012] Preferably, the tops of the flashing on both the front and rear sides of the vent are seamlessly connected to the walls of the water collection trough on the same side, and the bottoms of the flashing slope downwards and extend to the outer roof surface of the roof outside the vent.
