Technical Field
[0001] The utility model belongs to the field of lighting fixtures, and more specifically relates to an aluminum alloy lamp cup for preventing lamp beads from exploding. Background Art
[0002] A lamp cup refers to a cup-shaped lamp fixture with a conical shape. The larger diameter is about 3 - 5 cm. It belongs to a kind of light source and uses a super-high brightness light source, which is brighter than an ordinary spotlight. It mainly consists of a constant current driver, an optical lens, an LED light source, and a high thermal conductivity radiator housing. The principle adopts a parabolic surface design for flashlight focusing, which can well reduce light loss. It has the advantages of rich shapes, energy saving, and low temperature.
[0003] Since the light source on the lamp cup continuously emits heat during operation, the temperature inside the lamp cup continues to rise, resulting in affecting the normal operation of electronic components or the phenomenon of lamp beads exploding due to excessive temperature. The lamp cups in the prior art do not have a reliable explosion-proof design for safety settings, with a low safety factor and potential safety hazards. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide an aluminum alloy lamp cup for preventing lamp beads from exploding, which has the advantages of good heat dissipation and lamp bead explosion prevention.
[0005] To achieve the above purpose, the present utility model provides the following technical solutions:
[0006] An aluminum alloy lamp cup for preventing lamp beads from exploding, comprising a cup body, a lampshade, and a heat dissipation housing. The cup body is hollow inside and has openings at both ends. The lampshade is arranged at the cup mouth. The cup body is sleeved with the heat dissipation housing. The inner diameter of the heat dissipation housing is larger than the outer diameter of the cup body, and a heat dissipation channel is formed between the heat dissipation housing and the cup body;
[0007] A ventilation hole vertically penetrating the cup body is provided at the opening of the cup body. An air outlet hole communicating with the ventilation hole is provided on the inner wall of the cup body. Connection parts are extended at both openings of the cup body, and the connection parts are fixedly connected to the heat dissipation housing through bolts.
[0008] The advantages of this solution are at least as follows: Through the design of the heat dissipation housing, ventilation holes, and air outlet holes of the aluminum alloy lamp cup of the present utility model, when the light source in the cup body generates heat during operation, the air in the cup body is affected by the heat. As the working time of the light source passes, the temperature in the cup body will rise. The ventilation holes vertically penetrate both ends of the cup body, and the air outlet holes are interconnected with the ventilation holes, enabling the high-pressure and high-temperature gas to be discharged from the air outlet holes through the ventilation holes in a timely manner, greatly releasing the heat in the cup body. Since the air outlet holes are connected to the ventilation holes and the ventilation holes vertically penetrate both ends of the cup body, the high-temperature and high-pressure gas can be discharged to the outside through the air outlet holes from the ventilation holes, and circulate with the cold air outside the cup, preventing the lamp beads from exploding due to the excessive temperature in the cup body. Even if the lamp beads in the cup body accidentally explode, the design structure of the ventilation holes and the air outlet holes can alleviate the explosion, and the impact gas can also be promptly discharged outside the cup through the air outlet holes and the ventilation holes, with a high safety factor.
[0009] The present utility model is further configured as: A plurality of first heat dissipation holes are provided on the outer peripheral wall of the cup body, and the first heat dissipation holes communicate with the ventilation holes.
[0010] The advantages of this solution are at least as follows: By providing the first heat dissipation holes, the heat in the cup body can be discharged not only through the ventilation holes but also through the first heat dissipation holes to the heat dissipation channel formed between the heat dissipation housing and the cup body, enabling the heat to be quickly discharged through two places.
[0011] The present utility model is further configured as: A plurality of second heat dissipation holes are provided on the outer peripheral wall of the heat dissipation housing, and the arrangement of the second heat dissipation holes intersects with that of the first heat dissipation holes.
[0012] The advantages of this solution are at least as follows: By providing the second heat dissipation holes, when the heat in the cup body is discharged to the heat dissipation channel formed between the heat dissipation housing and the cup body through the first heat dissipation holes, the second heat dissipation holes can further discharge the heat in the heat dissipation channel out of the cup body, enabling the heat dissipation channel to remain connected to the outside air. By arranging the second heat dissipation holes to intersect with the first heat dissipation holes, when there are water droplets on the outer peripheral wall of the heat dissipation housing, it can prevent the water droplets from flowing through the second heat dissipation holes to the first heat dissipation holes and causing the inner wall of the cup body to be invaded by water.
[0013] The present utility model is further configured as: A plurality of isolation grooves are provided on the outer peripheral wall of the cup body.
[0014] The advantages of this solution are at least as follows: By providing the isolation grooves, when water droplets invade the outer peripheral wall of the cup body from the second heat dissipation holes, the isolation grooves can further block the water droplets in the isolation grooves, preventing further invasion of the water droplets. The water droplets in the isolation grooves can be slowly evaporated by the heat energy in the cup body.
[0015] The present utility model is further configured as: A blocking ring is provided at the orifice of the first heat dissipation hole.
[0016] The advantages of this solution are at least as follows: when water droplets invade the outer peripheral wall of the cup body from the second heat dissipation hole, the isolation groove further intercepts them. When the remaining water droplets do not flow into the isolation groove, the barrier ring can also defend the first heat dissipation hole, causing the water droplets to fall into the isolation groove.
[0017] The present utility model is further configured such that: a plurality of heat dissipation fins are distributed on the outer peripheral wall of the heat dissipation housing.
[0018] The advantages of this solution are at least as follows: the heat dissipation fins can effectively increase the contact area of the heat dissipation area with the air, thereby improving the heat dissipation efficiency of the lamp cup.
[0019] The present utility model is further configured such that: both ends of the heat dissipation fins are fixedly connected with O-shaped fixing rings.
[0020] The advantages of this solution are at least as follows: the O-shaped fixing rings can enhance the bearing capacity of the heat dissipation fins, improve the structural stability, and prevent the lamp cup from deforming or being damaged due to an accidental explosion inside or an external load.
[0021] The present utility model is further configured such that: an O-shaped waterproof part is provided around the ventilation hole at one end of the cup mouth, and a waterproof ring is further provided at the end of the O-shaped waterproof part.
[0022] The advantages of this solution are at least as follows: when water droplets invade the cup mouth, the O-shaped waterproof part can prevent the water droplets from flowing into the cup body through the ventilation hole. When the water droplets flow to the outer peripheral wall of the O-shaped waterproof part, the waterproof ring at the end of the O-shaped waterproof part can prevent the water droplets from further invading.
[0023] In summary, the present utility model has at least the following advantages:
[0024] 1. By providing the first heat dissipation hole, the heat in the cup body can be discharged not only through the ventilation hole, but also through the first heat dissipation hole to the heat dissipation channel formed between the heat dissipation housing and the cup body, so that the heat can be quickly discharged through two places; by providing the second heat dissipation hole, when the heat in the cup body is discharged to the heat dissipation channel formed between the heat dissipation housing and the cup body through the first heat dissipation hole, the second heat dissipation hole can further discharge the heat in the heat dissipation channel out of the cup body, so that the heat dissipation channel can be kept in communication with the outside air. By arranging the second heat dissipation hole to intersect with the first heat dissipation hole, when there are water droplets on the outer peripheral wall of the heat dissipation housing, it can prevent the water droplets from flowing through the second heat dissipation hole to the first heat dissipation hole and causing the inner wall of the cup body to be invaded by water;
[0025] 2. By setting the isolation groove, when water droplets invade the outer peripheral wall of the cup from the second heat dissipation hole, the isolation groove can further block the water droplets into the isolation groove to prevent further invasion of the water droplets. The water droplets in the isolation groove can be slowly evaporated by the heat energy in the cup; when the water droplets invade the outer peripheral wall of the cup from the second heat dissipation hole, the isolation groove further intercepts. When the remaining water droplets do not flow into the isolation groove, the barrier ring can also defend the first heat dissipation hole to make the water droplets flow into the isolation groove;
[0026] 3. By setting the heat dissipation fins, the heat dissipation fins can effectively increase the contact area between the heat dissipation area and the air, thereby improving the heat dissipation efficiency of the lamp cup; by setting the O-shaped fixing ring, the bearing capacity of the heat dissipation fins can be enhanced, the structural stability can be improved, and the lamp cup can be prevented from deforming or being damaged due to accidental explosion inside or external load; by setting the O-shaped waterproof part and the waterproof ring, when the cup mouth is invaded by water droplets, the O-shaped waterproof part can prevent the water droplets from flowing into the cup body from the ventilation hole.

[0030] The following further describes the present invention in detail with reference to the drawings.
[0031] An aluminum alloy lamp cup for preventing lamp beads from exploding, as Figure 1 and Figure 2As shown in the figure, it includes a cup body 1, a lampshade 2 and a heat dissipation housing 3. The inside of the cup body 1 is hollow and both ends are open. The lampshade 2 is arranged at the cup mouth. The cup body 1 is sleeved with the heat dissipation housing 3. The inner diameter of the heat dissipation housing 3 is larger than the outer diameter of the cup body 1, and a heat dissipation channel is formed between the heat dissipation housing 3 and the cup body 1. There is a ventilation hole 4 vertically penetrating the cup body 1 at the opening of the cup body 1. An air outlet hole 5 communicating with the ventilation hole 4 is provided on the inner wall of the cup body 1. Connection parts 6 are extendedly arranged at both open ends of the cup body 1, and the connection parts 6 are fixedly connected with the heat dissipation housing 3 through bolts. Through the design of the heat dissipation housing 3, the ventilation hole 4 and the air outlet hole 5 of the aluminum alloy lamp cup of the present invention, when the light source in the cup body 1 works and emits heat, the air in the cup body 1 is affected by the heat, and as the working time of the light source passes by, the temperature in the cup body 1 will rise. The ventilation hole 4 vertically penetrates both ends of the cup body 1, and the air outlet hole 5 communicates with the ventilation hole 4, so that the high-pressure and high-temperature gas can be discharged from the ventilation hole 4 through the air outlet hole 5 in time, and the heat in the cup body 1 is greatly released. Because the air outlet hole 5 communicates with the ventilation hole 4 and the ventilation hole 4 vertically penetrates both ends of the cup body 1, the high-temperature and high-pressure gas can be discharged to the outside through the air outlet hole 5 from the ventilation hole 4, and circulates with the cold air outside the cup body 1, preventing the lamp beads from exploding due to the too high temperature inside the cup body 1. Even if the lamp beads inside the cup body 1 accidentally explode, the design structure of the ventilation hole 4 and the air outlet hole 5 can make the explosion mitigated, and the impact gas can also be discharged out of the cup body 1 through the air outlet hole 5 and the ventilation hole 4 in time, with a high safety factor.
[0032] As Figure 1 shown, a plurality of first heat dissipation holes 7 are provided on the outer peripheral wall of the cup body 1, and the first heat dissipation holes 7 communicate with the ventilation hole 4 (refer to Figure 2 ). By providing the first heat dissipation holes 7, the heat in the cup body 1 can be discharged not only through the ventilation hole 4, but also the heat in the cup body 1 can be discharged into the heat dissipation channel formed between the heat dissipation housing 3 and the cup body 1 through the first heat dissipation holes 7, so that the heat can be quickly discharged through two places.
[0033] As Figure 1 shown, a plurality of second heat dissipation holes 8 are provided on the outer peripheral wall of the heat dissipation housing 3, and the arrangement of the second heat dissipation holes 8 is staggered with that of the first heat dissipation holes 7. By providing the second heat dissipation holes 8, when the heat in the cup body 1 is discharged into the heat dissipation channel formed between the heat dissipation housing 3 and the cup body 1 through the first heat dissipation holes 7, the second heat dissipation holes 8 can further discharge the heat in the heat dissipation channel out of the cup body 1, so that the heat dissipation channel can be kept communicating with the outside air. By staggering the arrangement of the second heat dissipation holes 8 with that of the first heat dissipation holes 7, when there are water drops on the outer peripheral wall of the heat dissipation housing 3, it can prevent the water drops from flowing through the second heat dissipation holes 8 to the first heat dissipation holes 7 and causing the inner wall of the cup body 1 to be invaded by water.
[0034] As Figure 1As shown in the figure, a plurality of isolation grooves 9 are provided on the outer peripheral wall of the cup body 1. By providing the isolation grooves 9, when water droplets invade the outer peripheral wall of the cup body 1 from the second heat dissipation hole 8, the isolation grooves 9 can further block the water droplets into the isolation grooves 9 to prevent the water droplets from further invading. The water droplets in the isolation grooves 9 can be slowly evaporated by the heat energy in the cup body 1.
[0035] As Figure 1 shown in the figure, a barrier ring 10 is provided at the orifice of the first heat dissipation hole 7. When water droplets invade the outer peripheral wall of the cup body 1 from the second heat dissipation hole 8, the isolation grooves 9 further intercept. When the remaining water droplets do not flow into the isolation grooves 9, the barrier ring 10 can also defend the first heat dissipation hole 7 to make the water droplets flow into the isolation grooves 9.
[0036] As Figure 1 shown in the figure, a plurality of heat dissipation fins 11 are distributed on the outer peripheral wall of the heat dissipation housing 3. The heat dissipation fins 11 can effectively increase the contact area between the heat dissipation area and the air, thereby improving the heat dissipation efficiency of the lamp cup.
[0037] As Figure 2 shown in the figure, O-shaped fixing rings 12 are fixedly connected to both ends of the heat dissipation fins 11. The O-shaped fixing rings 12 can enhance the bearing capacity of the heat dissipation fins 11, improve the structural stability, and prevent the lamp cup from deforming or being damaged due to an accidental explosion inside or an external load.
[0038] As Figure 1 shown in the figure, an O-shaped waterproof part 13 is provided around the ventilation hole 4 at one end of the cup mouth, and a waterproof ring 14 is further provided at the end of the O-shaped waterproof part 13. When water droplets invade the cup mouth, the O-shaped waterproof part 13 can prevent the water droplets from flowing into the cup body 1 from the ventilation hole 4. When the water droplets flow to the outer peripheral wall of the O-shaped waterproof part 13, the waterproof ring 14 at the end of the O-shaped waterproof part 13 can prevent the water droplets from further invading.
[0039] The working process and beneficial effects of the present utility model are as follows: Through the design of the heat dissipation housing 3, ventilation holes 4, and air outlet holes 5 of the aluminum alloy lamp cup of the present utility model, when heat is generated at the light source inside the cup body 1, the air inside the cup body 1 is affected by the hot air. As time passes during the operation of the light source, the temperature inside the cup body 1 will rise. The ventilation holes 4 vertically penetrate both ends of the cup body 1, and the air outlet holes 5 communicate with the ventilation holes 4, enabling the high-pressure and high-temperature gas to be discharged from the ventilation holes 4 through the air outlet holes 5 in a timely manner, greatly releasing the heat inside the cup body 1. Since the air outlet holes 5 communicate with the ventilation holes 4 and the ventilation holes 4 vertically penetrate both ends of the cup body 1, the high-temperature and high-pressure gas can be discharged to the outside through the air outlet holes 5 from the ventilation holes 4 and circulate with the cold air outside the cup body 1, preventing the lamp beads from exploding due to the excessively high temperature inside the cup body 1. Even if the lamp beads inside the cup body 1 accidentally explode, the design structure of the ventilation holes 4 and the air outlet holes 5 can mitigate the explosion, and the impact gas can also be timely discharged outside the cup body 1 through the air outlet holes 5 and the ventilation holes 4, with a high safety factor.
[0040] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
