Description
Technical Field
[0001] This utility model relates to the field of lighting fixtures, and in particular to an LED aluminum substrate wiring structure for a DOB industrial and mining lamp and the DOB industrial and mining lamp. Background Technology
[0002] High-bay industrial lamps, also known as high-ceiling lamps, are widely used in open spaces with high ceilings, such as industrial plants, production workshops, warehouses, and sports and entertainment venues. These scenarios typically require high-power lighting capabilities to meet the needs of large-area, long-distance illumination. However, high-power lamps continuously generate a large amount of heat during operation, and some installation locations have poor ventilation, leading to heat accumulation. If heat dissipation is not timely, it will not only affect the lighting effect but may also pose safety hazards. DOB (Digital Optical Module) technology, as an integrated AC high-voltage light source power supply, features no need for electrolytic capacitors, stable function, and is lighter and thinner. It integrates the driver power supply onto the light source substrate, eliminating the need for a separate driver mounting bracket and improving heat dissipation. However, existing DOB circular LED aluminum substrate layouts have the DOB power module in the middle and the LED light-emitting modules on the outer ring. This causes heat from the LED light-emitting modules to accumulate in the middle, resulting in excessively high temperatures for the DOB power module, significantly reducing its lifespan and reliability. To solve these problems, a new LED aluminum substrate wiring structure and a DOB industrial lamp are proposed. Utility Model Content
[0003] The purpose of this invention is to solve the problem that high-power industrial and mining lamps generate a lot of heat during operation, and poor ventilation in some installation scenarios leads to heat accumulation, affecting the lighting effect and posing safety hazards. The existing DOB industrial and mining lamps use a circular LED aluminum substrate with a layout of a central power module and an outer ring of light-emitting modules. The heat generated by the light-emitting modules accumulates in the middle, causing the DOB power module to overheat, which significantly reduces its lifespan and reliability.
[0004] The present invention adopts the following technical solution: A wiring structure for an LED aluminum substrate of a DOB industrial and mining lamp includes a circular LED aluminum substrate and a DOB power module and a light-emitting module disposed on the LED aluminum substrate. The DOB power modules are distributed in a ring along the outer edge of the LED aluminum substrate, and the light-emitting module is located in the middle of the LED aluminum substrate. It is composed of multiple fan-shaped structures forming a circular structure, and the overall circular structure is composed of multiple concentric rings. The negative electrode of the LED bead of the light-emitting module faces the center of the circular structure, and the positive electrode faces outward. The DOB power module has multiple power interfaces. Furthermore, there are four fan-shaped structures, and the multiple power interfaces of the DOB power module are connected to the four fan-shaped structures of the light-emitting module through one or more electrical connection methods such as series, parallel, and hybrid series-parallel connection. A DOB industrial and mining lamp includes a lamp body, a top cover, an air inlet, a slot, a replacement seat, a filter, a fan below the filter, and a mounting bracket below the lamp body, on which an LED aluminum substrate is mounted. Furthermore, the lamp body is a hollow cylindrical structure with a threaded circular opening at the upper end. The upper cover is connected to the lamp body by threads, and the upper cover is provided with a lifting ring for hoisting the entire device. Furthermore, a slot is provided in the middle of the lamp body, and several air inlets are provided above the slot. The several air inlets are evenly distributed in a circular shape around the outer wall of the lamp body and lead to the hollow part inside the lamp body. The replacement seat is fixed to the lamp body at the slot by a latch. Furthermore, the inner diameter of the replacement seat is the same as the diameter of the hollow structure of the lamp body. A filter screen is provided on the upper surface of the inside of the replacement seat to block impurities entering from the air inlet. A fan is provided below the filter screen via a bracket. The fan is connected to the power supply of the lamp body and faces the mounting bracket. Furthermore, the mounting bracket is located at the bottom of the lamp holder and is connected to the lamp holder via a cross bracket. The mounting bracket is annular, and its diameter is smaller than the inner diameter of the lamp holder. The mounting bracket has several fixing holes for mounting LED aluminum substrates. The LED aluminum substrates are installed on the mounting bracket by bolts extending into the fixing holes. There is a gap between the LED aluminum substrates and the side wall of the lamp holder to allow airflow.
[0005] The beneficial effects of this utility model are: The hollow columnar structure of the lamp body, combined with the air inlet and fan, forms a directional heat dissipation channel, which can promptly expel the heat generated by high-power operation, avoiding heat accumulation that could affect lighting effects or cause safety hazards. The locking and fixing of the replacement bracket and the filter design take into account both air intake cleanliness and maintenance convenience, preventing impurities from clogging and affecting heat dissipation efficiency. The ring structure of the mounting bracket and the gap between the LED aluminum substrate and the side wall of the lamp body ensure that the airflow evenly covers the LED aluminum substrate, eliminating heat dissipation dead zones. The LED aluminum substrate adopts an outer ring DOB power module and an inner ring light-emitting module layout, which changes the problem of heat accumulation caused by the traditional DOB power module being in the center. It allows the heat from the light-emitting module to diffuse in all directions, effectively reducing the temperature of the DOB power module and extending its life and reliability. The special orientation of the positive and negative electrodes of the LED beads further optimizes heat distribution and improves the overall heat dissipation uniformity. In addition, the threaded connection and lifting ring design of the top cover enhance installation flexibility and sealing, and the ring mounting bracket with cross bracket connection ensures the stable installation of the LED aluminum substrate. The synergistic effect of all components achieves the dual goals of efficient heat dissipation and reliable lighting. Attached Figure Description

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0010] Example 1 This utility model provides an LED aluminum substrate wiring structure for a DOB industrial and mining lamp and a DOB industrial and mining lamp, including a lamp body 1 and an LED aluminum substrate 11 mounted thereon. The lamp body 1 is a hollow cylindrical structure with a threaded circular opening at the top. A top cover 2 is threaded onto the opening, and a lifting ring is provided on the top cover 2 for hoisting the entire device. The threaded connection enables the top cover 2 to be detachably sealed, which is convenient for maintenance and ensures the integrity of the internal space of the lamp body 1. The lifting ring improves the ease of installation. The lamp body 1 has a slot 4 in the middle. Several air inlets 3 are evenly distributed around the outer wall of the lamp body 1 above the slot 4. The air inlets 3 lead to the hollow part inside the lamp body 1. A replacement seat 5 is set on the lamp body 1 at the slot 4 by a latch 8. The inner diameter of the replacement seat 5 is the same as the diameter of the hollow structure of the lamp body 1. A filter screen 6 is set on the upper surface of the inside of the replacement seat 5 to block impurities entering through the air inlets 3. A fan 7 is installed below the filter screen 6 by a bracket. The fan 7 is connected to the power supply of the lamp body 1 and faces the mounting bracket 9. External air is introduced through the air inlets 3. After being filtered by the filter screen 6, the airflow is guided by the fan 7 to flow towards the mounting bracket 9 to form a directional heat dissipation air channel. The replacement seat 5 fixed by the latch 8 is convenient for regular cleaning or replacement of the filter screen 6 to avoid impurities clogging the air intake efficiency. A mounting bracket 9 is provided at the bottom of the lamp body 1. The mounting bracket 9 is connected to the lamp body 1 through a cross bracket. The mounting bracket 9 is annular and its diameter is smaller than the inner diameter of the lamp body 1. The mounting bracket 9 is provided with several fixing holes 10. The LED aluminum substrate 11 is fixed in these fixing holes 10 by bolts. At the same time, a gap is reserved between the LED aluminum substrate 11 and the side wall of the lamp body 1 to allow airflow. The annular design of the mounting bracket 9 and the side gap are matched to ensure that the airflow can flow evenly around the LED aluminum substrate 11, reduce airflow dead angles, and improve the heat dissipation coverage. The LED aluminum substrate 11 is mounted on the mounting bracket 9 and consists of an outer ring of DOB power modules 12 and an inner ring of light-emitting modules 13. The DOB power modules 12 are arranged in a ring along the outer edge of the LED aluminum substrate 11. The light-emitting modules 13 are circular structures formed by connecting four fan-shaped structures. This circular structure consists of multiple concentric rings. The negative terminals of the LED beads in the light-emitting modules 13 face the center, and the positive terminals face outwards. The DOB power modules 12 have multiple power interfaces. The multiple power interfaces of the DOB power modules 12 are connected to the four fan-shaped structures of the light-emitting modules 13 through series, parallel, or hybrid connections. The layout uses one or more electrical connection methods to connect the LEDs. This layout changes the traditional design of the DOB power module 12 being centered. The DOB power module 12, which generates relatively concentrated heat, is placed on the outer ring. The heat from the light-emitting module 13 can diffuse to the surroundings instead of accumulating in the center. Combined with the airflow path from the fan 7 to the mounting bracket 9 and out through the gap between the LED aluminum substrate 11 and the side wall of the lamp body 1, the heat generated by the light-emitting module 13 can be effectively carried away, avoiding excessive heat concentration in the DOB power module 12. At the same time, the special orientation of the positive and negative electrodes of the LEDs may optimize the current distribution or heat conduction path, further assisting in heat dissipation.
[0011] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
