SANITARY COOLING PROFILE FOR LIGHTING FIXTURE Russian patent published in 2024 - IPC F21S8/04 

FIELD: lighting engineering; sanitary devices.

SUBSTANCE: invention relates to lighting engineering and sanitary devices, namely to lighting devices, and can be used as a cooling profile of lamps for industrial, domestic and architectural-design lighting with simultaneous sanitary treatment of room air. Sanitary-cooling profile for a lamp comprises a hollow housing with open ends, made of a heat-conducting material, on the outer surface of which there is a LED module connected to the power supply, installed in close proximity to one of the open ends of the housing and fixed by means of a detachable or permanent connection on the side or on the end surface of the housing with the possibility of air inlet into its inner cavity, wherein housing cross-section can have different shapes. Inside it, behind the LED module, there is a sanitary insert consisting of cathode and anode buses, having a profile that repeats the shape of the cross-section of the housing, each of which is slotted partitions made of pieces of aluminium wire with gaps between each other equal to Δ and connected to each other by pieces of wire also with a gap equal to Δ, each busbar is connected on its outer side with longitudinal stiffening ribs made of dielectric material, also interconnected. At that, the anode bus is arranged inside the cathode bus so that their cross sections of the wire are arranged relative to each other in a staggered order, and the lower ends of the stiffeners adjacent to the light-emitting diode module and the section of the housing located opposite them are equipped with connecting holes through which wires are passed, which are connected to both buses and the power supply of the sanitary insert located next to the power supply of the light-emitting diode module.

EFFECT: possibility of combining the cooling process of the light-emitting diode module of the lamp with parallel cleaning of the room air from harmful impurities and pathogens, which increases the environmental efficiency of the sanitary-cooling profile for the lamp.
