[detailed description of the invention]
Below in conjunction with the drawings and specific embodiments, LED lamp is illustrated further.
Please refer to Fig. 1 and Fig. 2, the LED lamp 100 of an embodiment comprises the first end cap 10, second end cap 20, Transparent Parts 30, holding part 40, light source fix heat sink 45, light source 48, fan 50, cooling pipe 60, pressing plate 72, securing member 74, first joint 82 and the second joint 84.First end cap 10 and the second end cap 20 are fixedly arranged on the two ends of Transparent Parts 30 respectively.Holding part 40, light source are fixed heat sink 45, light source 48, cooling pipe 60, pressing plate 72 and securing member 74 and are all contained in Transparent Parts 30.
Transparent Parts 30 is roughly transparent tubular.One end of Transparent Parts 30 and the first end cap 10 are tightly connected away from one end of cover plate 16, and the other end and second end cap 20 of Transparent Parts 30 are tightly connected.
Please refer to Fig. 3 and Fig. 4, the first end cap 10 is roughly the tube structure of truncated cone-shaped, its sidewall offers the first mating holes 12 and the second mating holes 14.First end cap 10 away from the second end cap 20 one end described in be provided with cover plate 16 (see Fig. 2).Cover plate 16 is for sealing the stub end of the first end cap 10.
Holding part 40 is roughly strip.The first end cap 10 and the second end cap 20 is fixed on respectively by two screws 401 in the two ends of holding part 40.Holding part 40 offers draw-in groove 403, draw-in groove 403 extends to the second end cap 20 from the first end cap 10.In present embodiment, holding part 40 has two, and separately, and the draw-in groove 403 of two holding parts 40 is oppositely arranged two holding parts 40.
Light source is fixed heat sink 45 and is roughly rectangular plate-like.Fixture 45 is between two holding parts 40, and light source fixes the draw-in groove 403 that the relative both sides of heat sink 45 are contained in two holding parts 40 respectively, thus light source is fixed heat sink 45 and be fixed in LED lamp 10.
Light source 48 is fixed on the middle part that light source fixes heat sink 45.
Fan 50 is fixed on the second end cap 20 and substantially between two holding parts 40.
Please again consult Fig. 2, cooling pipe 60 comprises liquid feeding end 62, outlet end 64 and the cooling section 66 between liquid feeding end 62 and outlet end 64.Cooling section 66 comprises the part of three sections of S-type sinuous extensions, thus adds the length of cooling section 66.Pressing plate 72 is installed with the cooling section 66 in cooling pipe 60, pressing plate 72 is fixed on light source by securing member 74 fixes heat sink 45, thus cooling pipe 60 is fixed to light source fixes heat sink 45, and liquid feeding end 62 and outlet end 64 correspond respectively to the first mating holes 12 and the second mating holes 14.In present embodiment, cooling pipe 60 is copper pipe.
First joint 82 and the second joint 84 are contained in the first mating holes 12 and the second mating holes 14 respectively.Be provided with the first sealing ring 824 between first joint 82 and the first mating holes 12 thus the first joint 82 and the first end cap 10 are tightly connected.Be provided with the second sealing ring 844 between second joint 84 and the second mating holes 14 thus the second joint 84 and the first end cap 10 are tightly connected.In present embodiment, the first joint 82 and the second joint 84 are explosion-proof copper pipe joint.First joint 82 is tightly connected with the liquid feeding end 62 of cooling pipe 60, and the second joint 84 is tightly connected with the outlet end 64 of cooling pipe 60.
During use, first joint 82 and the second joint 84 are connected with feed tube 92 and drain pipe 94 respectively, thus cooling liquid can be sent into the cooling section 66 of cooling pipe 60 by feed tube 92, first joint 82 and liquid feeding end 12, cooling liquid flows to outlet end 64 at cooling section 66 and discharges through the second joint 84 and discharging tube 94, thus the heat that light source 48 in use produces is taken out of, make LED lamp 100 have good radiating effect.Fan 50 forces the air of LED lamp 100 inside to flow, and makes LED lamp 100 interior temperature distribution even, thus the radiating effect strengthened further.
The cooling section 66 of cooling pipe 60 wriggles and extends in LED lamp 100, thus can change the shape of cooling section 66 according to the internal structure of LED lamp 100, and versatility is stronger.Meanwhile, according to the difference of applicable situation and the kind difference of the cooling requirements of LED lamp 100 being changed to the cooling medium be contained in cooling pipe 60, thus the radiating effect of LED lamp can be changed, the instructions for use of different occasion can be met.Be tightly connected between the Transparent Parts 30 of LED lamp 100 and the first end cap 10 and the second end cap 20, the first joint 82 and the second joint 84 are all tightly connected with the first end cap 10, thus the sealing of described LED lamp 100 is better.First joint 82 and the second joint 84 are explosion-proof copper pipe joint, thus described LED lamp 100 can be applied to explosion-proof place.
Be appreciated that, first mating holes 12 and the second mating holes 14 are not limited to be opened in the first end cap 10, also can be opened in the second end cap 10, also one of them in the first mating holes 12 and the second mating holes 14 can be opened in the first end cap 10, another is opened in the second end cap 20.Fan 50 is not limited to be fixed on the second end cap 20, also can be fixedly arranged on the first end cap 10 or Transparent Parts 30.Holding part 40 is not limited to two, also can be one, and now light source is fixed heat sink 45 side and engaged with the draw-in groove 403 of holding part 40.The cooling section 66 of cooling pipe 60 also can be fixed heat sink 45 wriggles at light source and extend two-layer or multilayer to increase the length of cooling section 66, thus reaches better radiating effect.Cooling pipe 60 and light source 48 are not limited to be arranged at the homonymy that light source fixes heat sink 45, also can be arranged at light source respectively and fix on two sides of heat sink 45.
Refer to Fig. 5, the LED lamp 200 of second embodiment of the invention is substantially identical with the LED lamp 100 of the first embodiment, its difference is: LED lamp 200 comprises two light sources and fixes heat sink 45 and two groups of light sources 48, the cooling section 66 of cooling pipe 60 is clamped between the opposite flank that two light sources fix heat sink 45, two groups of light sources 48 are fixedly arranged on two light sources respectively and fix on the reverse side of heat sink 45, thus LED lamp 200 forms ring type LED lamp, realize the illumination along the approximate 360 degree of scopes of tubular Transparent Parts circumference.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
