Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp cups, and in particular to a novel explosion-proof LED lamp cup. Background Art

[0002] LED lamp cup is a new type of lighting fixture that is composed of LED light source, constant current driver, optical lens and metal or other heat sink shell with high thermal conductivity. Compared with traditional halogen lamp cup, it has the characteristics of energy saving, low temperature, long life and rich colors.

[0003] For example, a Chinese patent with publication number CN216280895U discloses an LED explosion-proof lamp, including a shell, one end of the shell is fixedly connected to a fastening cylinder, the end of the fastening cylinder away from the shell is fixedly connected to an explosion-proof lampshade by bolts, the fastening cylinder is fixedly connected to a reflective cylinder and an aluminum substrate, the reflective cylinder is fixedly connected to a plurality of reflective cups, the reflective cup is fixedly connected to an LED lamp, the reflective cylinder is fixedly connected to the aluminum substrate on the side away from the explosion-proof lampshade, the side of the shell away from the explosion-proof lampshade is symmetrically fixedly connected to outlet pipes, the opposite ends of the two outlet pipes are provided with outlet ports, and the shell is fixedly connected to an adjustment seat on the end away from the explosion-proof lampshade. This kind of LED explosion-proof lamp has high practical value in terms of LED explosion-proof lamps;

[0004] The technical solution recorded in this proposal utilizes a cooling pipe and a coolant to transfer the heat generated by the power supply and the circuit control box, and utilizes a cooling fan and a ventilation grille to promote the air flow inside the outer shell, thereby achieving the purpose of heat dissipation. However, as the LED lamp continues to operate, only the first annular fin is used to cool the cooling pipe and the coolant, which is inefficient. When the temperature of the coolant cannot be lowered, it no longer has a heat-conducting effect, and is thus unable to dissipate heat and cool the interior of the LED lamp.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a new explosion-proof LED lamp cup is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0020] Furthermore, the shell is made of engineering plastics.

[0021] The beneficial effect of adopting the above further solution is that by setting the shell to be an engineering plastic material, the shell is made lighter and more resistant to high temperatures.

[0036] Embodiment 3 of a novel explosion-proof LED lamp cup of the utility model

[0037] Reference Figure 1-Figure 5 As shown, the explosion-proof lampshade 1002 is made of polycarbonate, a transparent explosion-proof film is bonded to the inner side of the explosion-proof lampshade 1002, the interior of the heat pipe 2005 is filled with coolant, the heat pipe 2005 is made of brass, and the shell 1001 is made of engineering plastic.

[0038] Specifically, the working principle of the new explosion-proof LED lamp cup is as follows: when in use, when the LED lamp board 1006 generates heat due to long-term operation, the first fan 2001 is started so that when it works, the cold air at the cold end of the first semiconductor refrigeration sheet 2002 is blown toward the LED lamp board 1006, thereby cooling it, and the excess air is discharged from the first ventilation grille 1003. When the first semiconductor refrigeration sheet 2002 works, the heat generated at its hot end is pumped into the heat pipe 2005 by starting the micro pump 2007 to circulate the coolant, thereby transferring the heat at the hot end of the first semiconductor refrigeration sheet 2002 to the interior of the cooling box 2003. At the same time, the second semiconductor refrigeration sheet 2006 is started, and its cold end refrigeration cools the heat pipe 2005, thereby cooling the coolant flowing inside it, so that it can better cool the hot end of the first semiconductor refrigeration sheet 2002, thereby promoting the cooling effect of its cold end. By installing a second fan 2004 on the upper end of the second semiconductor refrigeration sheet 2006, the hot end of the second semiconductor refrigeration sheet 2006 can be cooled, thereby improving the cooling effect of its cold end on the heat pipe 2005. The hot air blown out by the second fan 2004 is discharged from the interior of the housing 1001 through the second air grille 1004, so that the LED light board 1006 can operate stably for a long time.

[0039] It should be noted that, for a new type of explosion-proof LED lamp cup, the specific models and specifications of the first semiconductor refrigeration plate 2002, the second semiconductor refrigeration plate 2006, the first fan 2001, the second fan 2004, the LED lamp board 1006 and the micro pump 2007 need to be selected and determined according to the actual specifications of the device.
