Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a high-efficiency Chinese-style lamp. Background Technology

[0002] The Chinese lantern is a traditional and distinctive lamp. The existing Chinese lantern's lamp head assembly mainly consists of the lamp head body, lampshade, and light source assembly. The lamp head body is made of metal (such as stainless steel) and contains an internal circuit connection system, secured to the lamp post with bolts. The lampshade is made of UV-resistant and anti-aging acrylic or imported PMMA organic material, featuring high light transmittance, effectively filtering glare, and protecting the light source. The light source assembly includes an LED chip board, a lens board, and a controller, which adjusts the brightness and color temperature of the LED chips.

[0003] In existing technologies, to achieve high luminous efficiency in Chinese lanterns, one can focus on improving light energy utilization, reducing losses, and enhancing effective lighting effects. Therefore, for existing Chinese lanterns, simply installing a finned lamp cover on the top can upgrade the heat dissipation system and reduce losses. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency Chinese-style lamp to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is as follows:

[0006] This utility model discloses a high-efficiency Chinese-style lamp, comprising a lamp head body, a lampshade, and a light source assembly. The lampshade is disposed around the lamp head body, and the light source assembly is disposed inside the lampshade and connected to the lamp head body. The lamp head body includes a lamp cover and a heat pipe. The lamp cover has several fins, and the heat pipe is embedded in the fins. The light source assembly includes an LED bead plate. The fins and the heat pipe are both disposed on the top of the lampshade, and the fins and the heat pipe are positioned above the LED bead plate. The structure is optimized through the design of the fin array and heat pipe technology. The fin array increases the heat dissipation surface area and accelerates heat dissipation in combination with airflow. The heat pipe rapidly dissipates heat through a phase change evaporation-condensation cycle. When the Chinese-style lamp is working, the LED bead plate generates heat, which is simultaneously dissipated by the fins and the heat pipe, reducing the overall loss of the Chinese-style lamp and thus improving the effective light output.

[0007] Furthermore, the heat pipe includes a vacuum-sealed tube, a capillary, and a working fluid. The capillary is located on the inner wall of the vacuum-sealed tube, and the working fluid is located inside the vacuum-sealed tube, adsorbed onto the capillary. The heat pipe includes an evaporating end and a condensing end, which are opposite to each other, with the evaporating end positioned close to the LED bead plate. Simply put, when the evaporating end of the heat pipe is heated, the liquid in the capillary evaporates and vaporizes. The vapor flows to the condensing end under a small pressure difference, releasing heat and condensing into liquid. The liquid then flows back to the evaporating section due to capillary action. Specifically, heat is transferred through the heat pipe wall and the capillary filled with working fluid to the liquid-vapor interface. The liquid evaporates at the liquid-vapor interface in the evaporating end, and the vapor in the vapor chamber flows from the evaporating end to the condensing end. The vapor condenses at the liquid-vapor interface in the condensing end. Heat is transferred from the vapor-liquid interface to the cold source through the capillary, liquid, and pipe wall. Due to capillary action, the condensed working liquid flows back to the evaporating section.

[0008] Furthermore, the light source assembly also includes a lens plate, which has several lamp cavities and grooves inside the lamp cavities. The lamp bead plate has several LED lamp beads, which are disposed in the corresponding grooves. By designing specially designed grooves to accommodate the lamp cavities, the lens plate will not damage the LED lamp beads during the installation of the Chinese lantern.

[0009] Furthermore, since the Chinese-style lamp is exposed to sun and rain for extended periods, a sealing and waterproof design is necessary. The lamp head body also includes a lamp holder and a sealing ring. Both the lamp holder and the lamp cover have mounting grooves, and the sealing ring is located within the mounting groove. The mounting groove has a first baffle, and the top and bottom of the lamp cover both have second baffles. The sealing ring is located between the first and second baffles. This double baffle and sealing ring design effectively prevents water from entering the lamp cover.

[0010] Furthermore, the light source assembly also includes a reflector tower, which is located inside the lamp cover and below the LED bead plate and the lens plate. Due to the design of the reflector tower, the problem of light source obstruction needs to be considered. Therefore, there are gaps on both the LED bead plate and the lens plate. The width of the gaps is not less than the large diameter of the reflector tower. By designing gaps, the number of LED beads is reduced, and the light source is prevented from being obstructed by the reflector tower.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the structure is optimized by designing fin array and heat pipe technology. The fin array increases the heat dissipation surface area and accelerates heat dissipation by combining with air flow. The heat pipe quickly dissipates heat through phase change evaporation-condensation cycle. When the Chinese lantern is working, the lamp bead plate generates heat, which is simultaneously dissipated by the fins and heat pipe, reducing the overall loss of the Chinese lantern and thus improving the effective light output.

[0020] Please refer to Figures 1-7This utility model provides a high-efficiency Chinese-style lamp, including a lamp head body 1, a lampshade 2, and a light source assembly 3. The lampshade 2 is disposed around the lamp head body 1, and the light source assembly 3 is disposed inside the lampshade 2 and connected to the lamp head body 1. The lamp head body 1 includes a lamp cover 11 and a heat pipe 12. The lamp cover 11 is provided with a plurality of fins 111, and the heat pipe 12 is embedded in the fins 111. The light source assembly 3 includes an LED bead plate 31, and both the fins 111 and the heat pipe 12 are disposed within the lamp cover 2. The lampshade 2 is located on top, with the fins 111 and the heat pipe 12 positioned above the lamp bead plate 31. The structure is optimized through the design of the fin array 111 and the heat pipe 12. The fin array 111 increases the heat dissipation surface area and, combined with airflow, accelerates heat dissipation. The heat pipe 12 rapidly dissipates heat through a phase change evaporation-condensation cycle. When the lamp is working, the lamp bead plate 31 generates heat, which is simultaneously dissipated by the fins 111 and the heat pipe 12, reducing the overall loss of the lamp and thus improving effective light output.

[0021] Further, the heat pipe 12 includes a vacuum-sealed tube 121, a capillary 122, and a working fluid 123. The capillary 122 is disposed on the inner wall of the vacuum-sealed tube 121, and the working fluid 123 is disposed inside the vacuum-sealed tube 121, with the working fluid 123 adsorbed onto the capillary 122. The heat pipe 12 includes an evaporation end 124 and a condensation end 125, which are opposite to each other. The evaporation end 124 is located close to the LED bead plate 31. In simple terms, when the evaporation end 124 of the heat pipe 12 is heated, the liquid in the capillary 122 evaporates and vaporizes. The vapor flows to the condensation end 125 under a small pressure difference, releasing heat and condensing into liquid. The liquid then flows back to the evaporation section under the force of the capillary 122. Specifically, heat is transferred through the tube wall of the heat pipe 12 and the capillary 122 filled with working fluid 123 to the liquid-vapor interface (i.e., the vapor-vapor interface). Figure 3 (The hollow position), the liquid evaporates at the liquid-vapor interface in the evaporation end 124, the vapor in the vapor chamber flows from the evaporation end 124 to the condensation end 125, the vapor condenses at the liquid-vapor interface in the condensation end 125, the heat is transferred from the vapor-liquid interface to the cold source through the capillary 122, the liquid and the pipe wall, and the working liquid after condensation flows back to the evaporation section due to the action of the capillary 122.

[0022] Among them, capillary 122 is a liquid-absorbing core, which is made of porous material.

[0023] Furthermore, the light source assembly 3 also includes a lens plate 32, which has a plurality of lamp cavities 321 and a groove 322 inside each lamp cavity 321. The lamp bead plate 31 has a plurality of LED lamp beads, which are disposed in the corresponding grooves 322. By designing a special groove 322 to accommodate the lamp cavity 321, the lens plate 32 will not damage the LED lamp beads during the installation of the Chinese lantern.

[0024] Furthermore, since the Chinese lantern is exposed to sun and rain for extended periods, a well-sealed and waterproof design is necessary. The main body 1 of the lantern head also includes a lamp holder 13 and a sealing ring 14. The sealing ring 14 consists of a large sealing ring and a small sealing ring. The large sealing ring is located between the lamp cover 11 and the lamp shade 2, and the small sealing ring is located between the lamp holder 13 and the lamp shade 2. Both the lamp holder 13 and the lamp cover 11 are provided with mounting grooves 15, and the sealing ring 14 is located within the mounting grooves 15. The mounting groove 15 is provided with a first baffle 16, and the top and bottom of the lamp shade 2 are provided with second baffles 17. The sealing ring 14 is located between the first baffle 16 and the second baffle 17. Through the design of double baffles and sealing ring 14, water can be effectively prevented from entering the lamp shade 2.

[0025] Furthermore, the light source assembly 3 also includes a reflector tower 33, which is located inside the lamp cover 2 and below the lamp bead plate 31 and the lens plate 32. Due to the design of the reflector tower 33, the problem of light source obstruction needs to be considered. Therefore, both the lamp bead plate 31 and the lens plate 32 are provided with a gap 34. The width of the gap 34 is not less than the large diameter of the reflector tower 33. By designing the gap 34, the number of LED beads is reduced, and the light source is prevented from being obstructed by the reflector tower 33.

[0026] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
