In figure: 1-cooling water inlet pipe, 2-outlet pipe, the tight clamp of 3-, 4-lampshade end cap, 5-Transparent lamp shade, 6-LED light bar, 7-substrate, 8-insulating heat-conductive glue-line, 9-bolt, 10-collection spool.
Detailed description of the invention
In conjunction with Figure of description, the present invention is described in further detail, but the present invention is not limited to following example.
As shown in the figure, this is used for the LED lamp tube of light-catalyzed reaction, including having the substrate 7 sealing cavity, substrate 7 upper end arranges cooling water intake-outlet, cooling water inlet pipe 1 extends its hollow cavity bottom from substrate 7 upper end water inlet, outlet pipe 2 connects with the outlet of substrate 7 upper end, one group of LED 6 sticks to substrate 7 surface by insulating heat-conductive glue-line 8, LED 6 is connected with external circuit by collection spool 10, LED 6 is outside is equipped with Transparent lamp shade 5, the luminous energy that the most whole LED lamp tube sends is uniformly to surrounding divergent irradiation material, make the reaction of light-catalyzed reaction system uniformly, steadily.The described substrate 7 with sealing cavity is cylinder-like structure.Each bar LED 6 uniform intervals, be parallel to each other stick to substrate 7 surface by insulating heat-conductive glue-line 8.Cooling water inlet pipe 1 lower end is 5cm-10cm, preferably 6-8cm with the spacing of substrate 7 cavity bottom, so ensures the cooling water convection current displacement of whole LED intracavity, without dead liquid zone.Cooling water inlet pipe 1 is by the external running water valve of rubber water pipe, and by water adjusting valve door size, less cooling water flow i.e. can reach stable cooling effect, and this LED lamp tube can be universally used in tower and autoclave photochlorination apparatus.Cooling water inlet pipe 1 and water inlet position, substrate 7 upper end welded seal, outlet pipe 2 and outlet position, substrate 7 upper end welded seal.
In LED 6, the wave-length coverage of single light emitting diode is 300nm-600nm, preferably 450nm-500nm；The power of wall scroll LED 6 is 1W-1000W, preferably 100W-200W.Transparent lamp shade 5 upper end arranges lampshade end cap 4, and substrate 7 upper end is correspondingly arranged tight clamp 3, and lampshade end cap 4 is connected by bolt 9 locking with tight clamp 3, and the cavity between Transparent lamp shade 5 and substrate 7 is for sealing cavity.The thickness of insulating heat-conductive glue-line 8 is 0.1-0.5mm, specifically insulating resin, and LED 6 not only can be firmly pasted onto on substrate 7 by insulating heat-conductive glue-line 8, also has good insulation, heat conductivility.Substrate 7 uses aluminum high performance heat transfer material to be extruded from, its excellent heat conductivity, LED can produce heat and synchronize to pass.Transparent lamp shade 5 uses polyethylene, polypropylene, Merlon, acrylic, quartz or safety glass to make, and the light that Transparent lamp shade 5 both can allow LED send passes through and is irradiated to material, is possible to prevent again LED to be corroded by chemical reagent.
The present invention, compared with existing technology, has the advantages that
The present invention uses tap water as coolant, compared with the LED that existing air does coolant, because of more than 20 times that heat conductivity water is air, specific heat capacity water is about 3 times of air, and LED lamp tube of the present invention only needs fraction of cooling water just can reach highly stable cooling effect.The LED lamp tube provided such as the present invention is used in optical chlorinating reaction, coolant is made with the tap water under room temperature (25 DEG C), flow of inlet water only needs 0.5L/min, cooling water stable in outlet water temperature is at about 40 DEG C, lamp body temperature is consistent with cooling water leaving water temperature, under the conditions of Gai, the service life of the LED that the present invention provides be not less than 10000 hours, and material explosive polymerization blackening never occurs in process of the test.The most only by the cavity temperature of a simple running water valve the most operable control LED lamp tube of the present invention, avoid existing air to do the LED lamp tube of coolant needs to connect volume is big, the air-intake device of Heavy Weight, and the extra air-intake device connected too increases the insecurity of production.
