1. A LED lighting lamp cooled by a liquid agent comprising:
COB LED (chip on board) modules having an LED light source, whose supporting bodies include temperature sensors cooled with a cooling agent,
a load-bearing and lighting subassembly (1), having a cooling plate (12) with three threaded mounting openings (13, 14 and 15) arranged transversely, an inner surface (16) having channels (17) for the cooling agent flowing therethrough is permanently and tightly connected with a cover (22) equipped with neodymium magnets (19) magnetically connected to contacting neodymium magnets (53) of holders (44) fixing COB LED modules (29) equipped with COB LED diodes (33) and lenses (51),
a cooling subassembly (2) situated above the load-bearing and lighting subassembly (1) including a cooling fan (56) and a water radiator (57) placed thereon and detachably connected thereto,
wherein the load-bearing and lighting subassembly (1) and the cooling subassembly (2) are connected to each other by a first connecting pipe set (3) and a second connecting pipe set (4) such that an upper connector (68) of the first connecting pipe set (3) is screwed into the threaded opening (66) of the water chamber (63) of the water radiator, and two additional connectors (69) of the first connecting pipe set (3) are screwed into the threaded openings (14 and 15) of the cooling plate (12) of the load-bearing and lighting subassembly (1), and a threaded connecting pipe (54′) of a water pump (55) is screwed into the opening (13), while an upper connection (70) of the second connecting pipe set (4) is screwed into a threaded opening (67) of a second water chamber (64) of the water radiator (57), and a lower connection (71) of the second connecting pipe set (4) is screwed into a threaded connection (72) of a water pump (55), both of the subassemblies (1 and 2) are mounted in a housing (5) with a profile adapted to a shape of the cooling plate (12) and the water radiator (57).
