Description

Technical Field

[0001] The utility model relates to the technical field of COB lamp beads, in particular to a water cooling head reinforcement structure for COB lamp beads. Background Art

[0002] Traditional COB lamp beads generally include an aluminum substrate, circuits and light sources. They are high-efficiency integrated surface light source technology that directly attaches LED chips to a high-reflectivity mirror metal substrate. However, a large amount of heat is generated when the light source is powered on. Water cooling is usually used for heat dissipation. Circulating water is mainly used to take away the heat generated by the light source when it is powered on, thereby achieving a cooling effect and extending the service life of the COB lamp beads.

[0003] In the process of using water cooling to cool COB lamp beads, water repeatedly passes through the water cooling head and its own weight is entirely on the water cooling copper base plate. The water cooling copper base plate bears excessive load for a long time, becomes aged, and is prone to bending and damage, which in turn affects the normal use of the COB lamp beads. To address the above problems, we have introduced a reinforced structure for the water cooling head of COB lamp beads. Utility Model Content

[0004] The utility model discloses a water cooling head reinforcement structure for COB lamp beads. Since water repeatedly passes through the inside of the water cooling head and its own weight is completely on the water-cooled copper bottom plate, the water-cooled copper bottom plate bears excessive load for a long time, becomes aged, and is prone to bending and damage, thereby affecting the normal use of the COB lamp beads.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A reinforcement structure for a COB lamp bead water cooling head comprises a water-cooled copper base plate, a reinforcement mechanism is installed at the lower end of the water-cooled copper base plate, and the reinforcement mechanism is used to enhance the supporting bearing capacity of the water-cooled copper base plate; the water-cooled copper base plate comprises a square frame installed at the lower end of the water-cooled copper base plate, four sides of the square frame are equidistantly connected to first brackets, two groups of the first brackets are rotatably connected to support rods on the inner sides, a hollow cylinder is connected to the side of the support rod away from the first bracket, a wedge-shaped top block is connected to the side of the hollow cylinder close to the center point of the square frame, four sides of the inner side of the square frame are fixedly connected to fixed blocks, a double-sided wedge block is slidably connected to the middle of the fixed block, and single-sided wedge blocks are symmetrically slidably on both sides of the fixed block.

[0007] According to a further technical solution, a rubber pad is provided on one side of the double-sided wedge block and the single-sided wedge block close to the center point of the square frame.

[0008] By setting the rubber pad, the double-sided wedge block and the single-sided wedge block can prevent damage to the COB lamp bead copper plate during the clamping process.

[0009] According to a further technical solution, second brackets are fixed equidistantly on four sides below the square frame, and a cylindrical rod is connected between two groups of the second brackets, and the cylindrical rod is slidably connected to the hollow cylinder.

[0010] The cylindrical rod is provided to facilitate the directional displacement of the hollow cylinder.

[0011] According to a further technical solution, the wedge-shaped opening of the wedge-shaped top block matches the wedge-shaped openings of the double-sided wedge block and the single-sided wedge block.

[0012] By setting the wedge-shaped opening of the wedge-shaped top block to match the wedge-shaped openings of the double-sided wedge block and the single-sided wedge block, it is achieved that when the two groups of wedge-shaped top blocks are displaced inward or outward relative to each other, they can be squeezed through the wedge-shaped opening of the wedge-shaped top block, thereby causing the double-sided wedge block or the single-sided wedge block to move in the fixed block.

[0013] According to a further technical solution, threaded holes are provided on four sides of the water-cooled copper bottom plate and the square frame, and bolts are threadedly connected inside the threaded holes.

[0014] The square frame is stably mounted on the water-cooled copper base plate by setting bolts through threaded holes.

[0015] According to a further technical solution, a water cooling head is connected to the upper end of the water-cooled copper base plate, a COB lamp bead copper plate is installed in the middle of the lower end of the water-cooled copper base plate, and a refrigeration plate is arranged at the lower end of the COB lamp bead copper plate.

[0016] By setting up a water cooling head and a cooling plate, the temperature of the surface of the COB lamp bead copper plate can be cooled, thereby extending the service life of the COB lamp bead.

[0017] Beneficial effects of the utility model:

[0018] By installing a square frame at the lower end of the water-cooled copper base plate, the overall structural strength of the water-cooled copper base plate is improved, thereby strengthening the supporting effect of the water-cooled copper base plate. At the same time, by converting the downward pressure of the water-cooling head into a clamping force on the COB lamp bead copper plate, the COB lamp bead copper plate indirectly gives supporting force to the water-cooled copper base plate, offsetting the downward pressure of the water-cooling head, and further improving the supporting effect of the water-cooled copper base plate.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The utility model discloses a water cooling head reinforcement structure for a COB lamp bead, which is mainly used in the scenario of water circulation heat dissipation of the COB lamp bead.

[0026] Reference Figure 1 , Figure 3 and Figure 4 A reinforcing structure for a COB lamp bead water cooling head comprises a water-cooled copper bottom plate 1, a reinforcing mechanism 2 is installed at the lower end of the water-cooled copper bottom plate 1, and the reinforcing mechanism 2 is used to enhance the supporting bearing capacity of the water-cooled copper bottom plate 1; the water-cooled copper bottom plate 1 comprises a square frame 201 installed at the lower end of the water-cooled copper bottom plate 1, and the four sides below the square frame 201 are equidistantly connected to the first bracket 202, and the inner sides of the two groups of first brackets 202 are rotatably connected to support rods 203, and the side of the support rod 203 away from the first bracket 202 is connected to a hollow cylinder 204, and the side of the hollow cylinder 204 close to the center point of the square frame 201 is connected to a wedge-shaped top block 205, and the four sides inside the square frame 201 are equidistantly connected to the first bracket 202. A fixed block 206 is fixedly connected to the edge, a double-sided wedge block 207 is slidably connected to the middle of the fixed block 206, single-sided wedge blocks 208 are symmetrically slidably arranged on both sides of the fixed block 206, a rubber pad 209 is arranged on the side of the double-sided wedge block 207 and the single-sided wedge block 208 close to the center point of the square frame 201, and second brackets 2010 are equidistantly fixed on the four sides below the square frame 201, a cylindrical rod 2011 is connected between the two groups of second brackets 2010, the cylindrical rod 2011 is slidably connected to the hollow tube 204, the wedge-shaped mouth of the wedge-shaped top block 205 is consistent with the wedge-shaped mouth of the double-sided wedge block 207 and the single-sided wedge block 208, and a water-cooled head 5 is connected to the upper end of the water-cooled copper bottom plate 1.

[0027] In this embodiment, in the process of using water cooling to dissipate heat for COB lamp beads for a long time, since the water cooling head 5 is installed on the upper end of the water-cooled copper bottom plate 1, the water flows through for a long time, and the water-cooled copper bottom plate 1 ages. The bearing capacity of the water-cooled copper bottom plate 1 is limited. In order to prevent deformation and damage, a square frame 201 is installed at the lower end of the water-cooled copper bottom plate 1 to improve the overall structural strength of the water-cooled copper bottom plate 1, thereby strengthening the supporting effect of the water-cooled copper bottom plate 1. When the square frame 201 is installed, the water-cooled copper bottom plate 1 is subjected to the pressure of the water cooling head 5, and the left and right When the two sides are deformed and bent inward, the square frame 201 is slightly bent, and the pressure is transmitted to the support rod 203 through the first bracket 202, causing the two sets of hollow tubes 204 to move inward on the cylindrical rod 2011. The displacement of the two sets of hollow tubes 204 simultaneously drives the two sets of wedge-shaped top blocks 205 to move inward synchronously. The wedge-shaped openings of the two sets of wedge-shaped top blocks 205 squeeze the double-sided wedge block 207, causing the double-sided wedge block 207 to slide on the fixed block 206 toward the center of the water-cooled copper bottom plate 1, and the rubber pad 209 and the COB lamp beads The surface of the copper plate 6 is pressed and adhered to realize the clamping of the COB lamp bead copper plate 6, thereby improving the fixing effect of the COB lamp bead copper plate 6. At the same time, by converting the downward pressure of the water-cooling head 5 into the clamping force of the COB lamp bead copper plate 6, the COB lamp bead copper plate 6 gives the water-cooled copper bottom plate 1 a supporting force in disguise, thereby offsetting the downward pressure of the water-cooling head 5, thereby further improving the supporting effect of the water-cooled copper bottom plate 1. When the left and right sides of the water-cooled copper bottom plate 1 are deformed and bent outward under pressure, the deformation causes the support rod 203 to drive the hollow cylinder 2 04 together with the two groups of wedge-shaped top blocks 205 move outward on the cylindrical rod 2011, and the wedge-shaped mouths of the two groups of wedge-shaped top blocks 205 squeeze the single-sided wedge block 208, and the single-sided wedge block 208 slides toward the center point of the water-cooled copper bottom plate 1, prompting the single-sided wedge block 208 to clamp the COB lamp bead copper plate 6, thereby achieving that the internal and external deformations of the water-cooled copper bottom plate 1 can be converted into the clamping force for the COB lamp bead copper plate 6, and at the same time, the COB lamp bead copper plate 6 provides reverse support force to the water-cooled copper bottom plate 1, thereby enhancing the support effect of the water-cooled copper bottom plate 1.

[0028] Reference Figure 2 In a preferred embodiment, threaded holes 4 are provided on all four sides of the water-cooled copper bottom plate 1 and the square frame 201, and bolts 3 are threadedly connected inside the threaded holes 4;

[0029] In this embodiment, bolts 3 penetrate through the threaded holes 4 on the water-cooled copper bottom plate 1 and the square frame 201 at the same time, so that the square frame 201 is stably fixed on the surface of the water-cooled copper bottom plate 1, thereby improving the overall structural strength of the water-cooled copper bottom plate 1.

[0030] Reference Figure 1 and Figure 3 In a preferred embodiment, a COB lamp bead copper plate 6 is installed in the middle of the lower end of the water-cooled copper bottom plate 1, and a cooling plate 7 is provided at the lower end of the COB lamp bead copper plate 6;

[0031] In this embodiment: the temperature emitted by the COB lamp beads installed on the surface of the COB lamp bead copper plate 6 is transmitted to the cooling plate 7, and the temperature absorbed by the cooling plate 7 is taken away by the water circulation inside the water cooling head 5, thereby achieving a cooling effect.
