Description

Technical Field

[0001] This invention relates to a lamp post structure for use in the field of photocatalysis, specifically a splicable lamp panel for a high-power LED lamp post light source. Background Technology

[0002] Commonly used tube-type light sources for photocatalysis include high-pressure mercury lamps, xenon lamps, mercury-xenon lamps, and metal halide lamps. During the photocatalytic process, cooling of the light source is typically achieved through an external cold trap. These light sources perform well at specific wavelengths; for example, mercury lamps perform well in the ultraviolet range, and xenon lamps perform well in simulating sunlight. However, they perform poorly at single wavelengths or when the wavelength is tunable. LEDs have irreplaceable advantages in these two aspects. In addition, the light source has higher light power output at certain wavelengths and greater deformability to meet the requirements of small size and multiple lengths. However, LEDs themselves require adequate heat dissipation to operate efficiently. Existing technology CN222543793U discloses an LED lamp post light source, in which multiple LEDs are connected in series on each facet of the main body, using a constant current power supply. When the number of LEDs connected in series is too large, the power supply needs to provide a constant high voltage, thus requiring higher-grade discrete components such as rectifier bridges, capacitors, MOSFETs, and LEDs, increasing costs. Switching and rectification losses and leakage inductance spikes under high voltage are more difficult to handle; EMI suppression and isolation requirements are also higher. Therefore, the length of each facet is limited, not exceeding 40cm.

[0003] As the number of LEDs connected in series increases, the "single point of failure" characteristic of the series link becomes apparent: an open circuit in any one LED will cause the entire string to fail. If an LED is short-circuited, the redistribution of current in the series can also cause overdrive or uneven brightness on different facets of the lamp post. In addition, existing LED light boards are mostly connected to the lamp post by soldering, which makes maintenance and replacement inconvenient and hinders flexible modular expansion.

[0004] Therefore, there is an urgent need in this field for a splicable light panel for high-power LED light column light sources to solve the above-mentioned technical bottlenecks. Summary of the Invention

[0005] To address the above technical problems, this invention proposes a splicable LED light column light source panel. The LED light column light source includes an external control box and a polygonal hollow metal prism. Multiple LED light panels are detachably mounted sequentially on each facet of the prism along the longitudinal direction from the starting end. Each LED light panel has two spaced main conductors attached to its surface. Multiple LED beads are connected in series between the two main conductors via branch conductors. Corresponding main conductors on adjacent LED light panels along the longitudinal direction are electrically connected to each other. The two main conductors of the first LED light panel near the starting end on the prism are electrically connected to the circuit board inside the external control box via leads. The surfaces of the main conductors and branch conductors are covered with an insulating layer.

[0006] The circuit board is electrically connected to the electrical control box, which provides a constant voltage power supply to the LED light board.

[0007] The prism is 1 to 10 meters long, and the total power of all LED lights on each face of the prism is 1 to 50 kW.

[0008] The LED light board is a copper substrate with a thickness of 1mm-3mm, and is manufactured using a thermoelectric separation process.

[0009] Each of the main conductors has an electrode crimping ring at both ends. The side of the electrode crimping ring facing away from the LED light board is exposed, while the other sides are coated with an insulating layer. A through hole penetrating the LED light board is provided in the center of the electrode crimping ring. Multiple LED lights are connected in series between the two electrode crimping rings at at least one end of each LED light board through a branch conductor. The corresponding electrode crimping rings on adjacent LED light boards along the longitudinal direction are electrically connected to each other.

[0010] The LED light board is fixed to the edge of the prism by pins. The corresponding electrode crimping rings on adjacent LED light boards respectively contact the two ends of the same conductive sheet and are electrically connected through the conductive sheet. The pins pass through the insulating ring, the conductive sheet and the through hole in sequence, and are used to press one end of the conductive sheet between the insulating ring and the electrode crimping ring. The diameter of the hole through which the pins pass through the two ends of the conductive sheet is larger than the diameter of the through hole and the pin.

[0011] The branch conductor is constructed in a U-shape and is positioned between the two main conductors, and is insulated from the main conductors.

[0012] Two rows of LED lights are connected in series on the branch conductor. Each row of LED lights has the same specifications and the same number of lights. Each row of LED lights is located close to one of the main conductors. Compared with the prior art, the beneficial effects of the present invention are: 1. Modular structural design, convenient assembly and maintenance, and strong expandability. The LED light board adopts a modular design with unique electrode pressing structures at both ends. The electrode pressing ring is pressed by conductive sheets, and the insulating ring isolates the pins and conductive sheets. Soldering is not required, which can realize quick assembly, repair and replacement of LED light boards. It also greatly facilitates flexible expansion of length and power.

[0013] 2. After each LED light board is connected in series, multiple rows of LED light strings are connected in parallel. Each LED light is powered by a constant voltage power supply, which enables low-voltage operation, reduces the cost of discrete components, and allows the LED light column light source to be extended in length without being limited by the voltage of the power supply.

Detailed Implementation

[0015] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0016] Example: like Figures 1 to 6 As shown, a high-power LED light column light source adopts a modular design, including an external control box and a polygonal hollow metal prism 1 housed in a glass sleeve 4. Each facet of the prism 1 is fixedly mounted with multiple splicable LED light panels 2 along the longitudinal direction, starting from the first end near the external control box.

[0017] The prism 1 is made of aluminum alloy, brass, copper, stainless steel, or silicon carbide, with aluminum alloy being preferred.

[0018] The splicable LED light panel 2 is made of insulating material and is a copper substrate with a thickness of 1mm-3mm, manufactured using a thermoelectric separation process. Two spaced-apart main conductors 21 are attached to the surface of the LED light panel 2. The surface of the main conductors 21 is covered with an insulating layer, and both ends of each main conductor 21 extend to an electrode crimping ring 15 at both ends of the LED light panel 2. The side of the electrode crimping ring 15 facing away from the LED light panel 2 is exposed, while the other sides are coated with an insulating layer. The electrode crimping ring 15 includes a positive electrode crimping ring 15b and a negative electrode crimping ring 15a. Crimping rings with the same electrode are connected to the same main conductor 21. Multiple LED beads 3 are connected in series between the positive electrode crimping ring 15b and the negative electrode crimping ring 15a at at least one end of each LED light panel 2 via a branch conductor 22. Corresponding electrode crimping rings 15 on adjacent LED light panels 2 along the longitudinal direction are electrically connected to each other. The surface of the branch conductor 22 is covered with an insulating layer. The number of LED beads 3 connected in series on each LED light panel 2 is equal, and they are of the same specification. The two main lines 21 of the first LED light board 2 near the starting end on the prism 1 are electrically connected to the circuit board in the external control box through leads. The circuit board is electrically connected to the electrical control box, which provides a constant voltage power supply to the LED light board 2.

[0019] When the LED bead 3 is powered on, it can emit a light source with a wavelength of 230nm-800nm.

[0020] Furthermore, the branch conductor 22 is constructed in a U-shape and is disposed between the two main conductors 21, and is insulated from the main conductors 21. Two rows of LED lights are connected in series on the branch conductor 22. Each row of LED lights has the same specifications and the same number. Each row of LED lights is close to one main conductor 21.

[0021] Furthermore, a through hole 9 is centrally located inside the electrode crimping ring 15, penetrating the LED light panel 2. The LED light panel 2 is fixed to the edge of the prism 1 by a pin. The corresponding electrode crimping rings 15 on adjacent LED light panels 2 are respectively connected to both ends of the same conductive sheet 16 and electrically connected through the conductive sheet 16. The pin 10 passes through the insulating ring 14, the conductive sheet 16 and the through hole in sequence, and is used to press one end of the conductive sheet 16 between the insulating ring 14 and the electrode crimping ring 15. The diameter of the hole through which the pin 10 penetrates the conductive sheet 16 is larger than the diameter of the through hole 9 and the pin 10.

[0022] Furthermore, the length of the prism 1 is 1 to 10 meters, and the total power of all LED lights on each face of the prism 1 is 1 to 50 kW.

[0023] Furthermore, the high-power LED light column light source glass sleeve 4 has a large flange panel 11 at its first end. A water inlet pipe 13 is located inside the hollow polygonal hollow metal prism 1. One end of the water inlet pipe 13 extends from inside the glass sleeve 4 and is threadedly connected to the large flange panel 11. A water-cooling inlet 6 is centrally located on the end face of the large flange panel 11 away from the glass sleeve 4. The water-cooling inlet 6 is connected to the water inlet pipe 13. A water-cooling outlet 7 is also located on the end face of the large flange panel 11, situated to one side of the water inlet pipe 13. The water inlet pipe 13 is made of stainless steel or aluminum alloy, preferably aluminum alloy.

[0024] Furthermore, a sealing gasket is provided between the large flange panel 11 and the glass sleeve 4.

[0025] Furthermore, each facet of the prism 1 has an anti-collision strip 9 between the LED light panel 2 and the glass sleeve 4. The anti-collision strip 9 is located between two rows of LED beads on the LED light panel 2 and is made of Teflon, which can both prevent collisions and reflect light, improving light utilization. A water inlet pipe 13 is provided inside the hollow prism 1. A centrally located flange 12, the same number as the facets, is evenly distributed between the water inlet pipe 13 and the inner wall of the prism 1. The centrally located flange 12 is located on the vertical line of the facet, allowing the water inlet pipe 13 to be effectively centered, ensuring uniform flow distribution. The second end of the prism 1, away from the starting end, is closed. The other end of the water inlet pipe 13 extends to the second end of the prism 1, connecting the water inlet pipe 13 with the return water chamber between the water inlet pipe 13 and the prism 1 at that end. The cavity 5 between the glass sleeve 4 and the prism 1 is filled with inert gas.

[0026] Furthermore, the glass sleeve 4 is made of ultra-white glass, high borosilicate glass, or quartz glass, preferably quartz glass.

[0027] This invention, through the aforementioned structural design and liquid application, effectively solves the problems of poor heat dissipation and safety in traditional LED light columns, making it particularly suitable for industrial photocatalysis scenarios requiring high power density and uniform light emission from the column surface. Furthermore, it allows for customization of the light column's light source length from 1 meter to 10 meters and its power from 1 kW to 50 kW according to actual needs.

[0028] Although the present invention has been described in detail through the above embodiments, those skilled in the art should understand that various modifications and variations can be made to the above embodiments without departing from the technical principles of the present invention, and these modifications and variations should also be considered within the scope of protection of the present invention.
