Description

Technical Field

[0001] This utility model relates to the field of energy-saving lamp technology, specifically to a negative ion energy-saving lamp. Background Technology

[0002] Negative ion energy-saving lamps are innovative lighting devices that cleverly combine negative ion generation technology with energy-saving lighting functions. The built-in negative ion generator uses carbon brushes to produce corona discharge under DC high voltage, releasing a large number of electrons that combine with oxygen molecules in the air to form negative ions. These negative ions not only activate oxygen molecules in the air, making them easier for the human body to absorb and effectively preventing "air conditioning sickness," but also purify the air, removing pollutants such as smoke, harmful gases, organic odors, dust, and pollen, causing them to undergo non-toxic reactions and decompose in the air, thus significantly improving indoor air quality.

[0003] However, traditional negative ion energy-saving lamps have significant heat dissipation problems. Due to the lack of an effective heat dissipation structure, internal heat easily accumulates. High-temperature environments not only accelerate the aging of circuit components inside or near the lamp, shortening the lamp's lifespan, but may also cause the outer casing to deform or melt due to overheating, leading to safety hazards. Therefore, we propose a new type of negative ion energy-saving lamp. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a negative ion energy-saving lamp that solves the heat dissipation problem of traditional negative ion energy-saving lamp tubes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a negative ion energy-saving lamp, including a lamp holder and a negative ion lamp tube fixedly installed at the bottom of the lamp holder, wherein a heat dissipation and cooling mechanism is provided on the lamp holder.

[0006] The heat dissipation and cooling mechanism includes a fan box fixedly installed on the outer circular surface of the lamp holder, a cooling plate fixedly installed on the inner wall of the fan box, a number of heat dissipation fins fixedly installed on the top of the cooling plate, and an airflow generating structure fixedly installed on the fan box.

[0007] The inner side of the air box is symmetrically equipped with guide pipes that communicate with the inner cavity of the air box. An outer air ring and an inner air ring are fixedly installed on the guide pipes. The outer air ring and the inner air ring communicate with the inner cavity of the guide pipes. Several cold air outlets are opened on the outer air ring and the inner air ring. The air outlet of the cold air outlet faces the negative ion lamp tube.

[0008] Preferably, the air box is made of heat-insulating material; the connection between the cooling element and the air box has good sealing performance; the cooling element is made of semiconductor material; the cooling surface of the cooling element faces downward and the heating surface of the cooling element faces upward.

[0009] Preferably, the heat dissipation fins are generally wavy, wherein the heat dissipation fins are adapted to the air box, and the heat dissipation fins are evenly distributed in a circumferential shape.

[0010] Preferably, the airflow generating structure includes a mounting bracket symmetrically installed on the outer circular surface of the air box, a micro air pump is fixedly installed on the inner side of the mounting bracket, and the output end of the micro air pump is fixedly connected to an air guide bend that communicates with the inner cavity of the air box.

[0011] Preferably, the inner air ring is located on the inner side directly above the negative ion lamp tube, and the outer air ring is located on the outer side directly above the negative ion lamp tube. The inner air ring, the outer air ring, and the guide tube are all fixedly connected to the lamp holder.

[0012] Preferably, the lamp holder is electrically connected to the negative ion lamp tube, the cooling element, and the micro air pump, wherein the lamp holder is connected in series with the negative ion lamp tube, the cooling element, and the micro air pump.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model utilizes a heat dissipation and cooling mechanism that combines a cooling chip and a micro air pump. The semiconductor cooling chip actively cools the airflow, and the combination with a directional cold air circulation system driven by the micro air pump significantly improves heat dissipation efficiency. The cold air evenly covers the inner and outer surfaces of the lamp tube through the annular cold air outlet of the inner and outer air rings, effectively eliminating the problems of lamp tube aging, deformation, and circuit component damage caused by localized heat accumulation in traditional lamps, thus greatly extending their service life.

[0015] 2. This utility model uses a heat-insulating box and wavy, circumferentially distributed heat dissipation fins to achieve efficient cooling at the cold end of the cooling chip. At the same time, the heat dissipation fins quickly diffuse the residual heat from the heating surface. Combined with the heat insulation properties of the heat-insulating box, it isolates external thermal interference, ensuring that energy loss is minimized during the delivery of cold air, thus maintaining cooling stability and avoiding additional energy consumption.

[0016] 3. This utility model forms a surrounding three-dimensional cooling air duct through the symmetrical layout of the outer and inner air rings and the diversion design of the guide pipe, so that the cold air accurately covers the core heat-generating area of ​​the lamp tube. Combined with the adjustable airflow intensity of the micro air pump, the heat dissipation intensity can be dynamically optimized according to the working status of the lamp, reducing operating energy consumption while ensuring heat dissipation effect, and solving the problems of low energy efficiency and safety hazards caused by the single heat dissipation method of traditional lamps.

[0028] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0029] This utility model provides a technical solution:

[0030] Please see Figures 1-6 A negative ion energy-saving lamp includes a lamp holder 1 and a negative ion lamp tube 2 fixedly installed at the bottom of the lamp holder 1. A heat dissipation and cooling mechanism 3 is provided on the lamp holder 1.

[0031] The heat dissipation and cooling mechanism 3 includes a wind box 301 fixedly installed on the outer circular surface of the lamp holder 1. A cooling plate 302 is fixedly installed on the inner wall of the wind box 301. Several heat dissipation fins 303 are fixedly installed on the top of the cooling plate 302. An airflow generating structure 304 is fixedly installed on the wind box 301. A guide pipe 305 communicating with the inner cavity of the wind box 301 is symmetrically installed on the inner side of the wind box 301. An outer air ring 306 and an inner air ring 307 are fixedly installed on the guide pipe 305. The outer air ring 306 and the inner air ring 307 communicate with the inner cavity of the guide pipe 305. Several cold air outlets 308 are opened on the outer air ring 306 and the inner air ring 307. The air outlets of the cold air outlets 308 face the negative ion lamp tube 2.

[0032] When the lamp is powered on, the airflow generation structure 304 (including a miniature air pump 3042) draws outside air into the air box 301 made of insulating material through the air guide bend 3043. The cooling surface of the cooling chip 302 faces downwards to actively cool the airflow, forming a cold air stream. The cooled air is then diverted through symmetrically distributed guide pipes 305 to the outer air ring 306 and inner air ring 307, and then evenly blown at a specific angle onto the inner and outer surfaces of the negative ion lamp tube 2 through the ring array of cold air outlets 308, forming a three-dimensional surrounding cooling air duct that precisely covers the core heating area of ​​the lamp tube and eliminates local heat accumulation. At the same time, the residual heat generated by the heating surface of the cooling chip 302 is rapidly diffused through the top wave-shaped heat dissipation fins 303, and combined with the insulation characteristics of the air box 301, it isolates external heat interference, ensuring that energy loss is minimized during the cold air delivery process. This device achieves a highly efficient combination of active cooling and passive heat dissipation through the synergistic effect of semiconductor refrigeration and directional cold air circulation driven by a micro air pump 3042. This not only significantly improves heat dissipation efficiency and avoids lamp tube aging, deformation, and circuit component damage caused by high temperatures in traditional lamps, but also optimizes energy consumption and extends the lifespan of lamps through dynamically adjustable airflow intensity. At the same time, it maintains the stable working state of the negative ion generator, fundamentally solving the safety hazards and performance degradation problems caused by insufficient heat dissipation.

[0033] In some embodiments, the air box 301 is made of heat-insulating material; the connection between the cooling plate 302 and the air box 301 has good sealing performance; the cooling plate 302 is made of semiconductor material; the cooling surface of the cooling plate 302 faces downward and the heating surface of the cooling plate 302 faces upward.

[0034] In this embodiment,

[0035] The air box 301 is made of heat-insulating material, which reduces heat exchange between the inside and outside of the air box through physical isolation. This ensures that the energy loss of the cooled air after being cooled by the cooling element 302 is minimized during transportation, maintaining cooling stability. The high-sealing design at the connection between the cooling element 302 and the air box 301 effectively prevents cold air leakage or infiltration of external hot air, ensuring cooling efficiency. The cooling element 302 uses semiconductor material and utilizes the Peltier effect to achieve active cooling. When powered on, the cooling surface faces downwards and is tightly attached to the inside of the air box 301, directly and efficiently cooling the intake airflow to form a cold airflow. The heating surface faces upwards and is tightly attached to the top corrugated heat dissipation fins 303, quickly dissipating waste heat through natural convection or ambient airflow, preventing the heating surface temperature from becoming too high and affecting cooling performance. This design, through directional thermal management with separate hot and cold ends, enhances the efficiency of cold air generation and transportation, ensures rapid discharge of waste heat, solves the problem of low energy efficiency caused by uneven heat dissipation in traditional lamps, reduces operating energy consumption, and extends the lifespan of the lamps.

[0036] In some embodiments, the heat dissipation fins 303 are generally wavy, wherein the heat dissipation fins 303 are adapted to the air box 301, and the heat dissipation fins 303 are evenly distributed in a circumferential shape.

[0037] In this embodiment, the heat dissipation fins 303 adopt a wave-shaped design, which significantly improves heat dissipation efficiency by increasing the contact area with air; its circumferentially uniformly distributed layout allows heat to be evenly diffused along the outer wall of the air box 301, avoiding excessively high local temperatures. The matching structure between the heat dissipation fins 303 and the air box 301 ensures that the waste heat generated by the heating surface of the cooling chip 302 can be quickly conducted to the fin surface and efficiently dissipated through natural convection or ambient airflow.

[0038] In some embodiments, the airflow generating structure 304 includes a mounting bracket 3041 symmetrically mounted on the outer circular surface of the air box 301. A micro air pump 3042 is fixedly mounted on the inner side of the mounting bracket 3041, and the output end of the micro air pump 3042 is fixedly connected to an air guide bend 3043 that communicates with the inner cavity of the air box 301.

[0039] In this embodiment, the airflow generating structure 304 fixes the micro air pump 3042 to the mounting bracket 3041 symmetrically installed on the outer circular surface of the air box 301, ensuring its operational stability. After being powered on, the micro air pump 3042 draws in air from the outside and delivers it to the inner cavity of the air box 301 through the air guide bend 3043, forming a directional airflow circulation. The interconnected design of the air guide bend 3043 ensures that the airflow is efficiently introduced into the interior of the air box 301, so that the cold air is sprayed out from the cold air outlet 308 and fully contacts the cooling chip 302 for cooling.

[0040] In some embodiments, the inner air ring 307 is located on the inner side directly above the negative ion lamp tube 2, and the outer air ring 306 is located on the outer side directly above the negative ion lamp tube 2. The inner air ring 307, the outer air ring 306, and the guide tube 305 are all fixedly connected to the lamp holder 1.

[0041] In this embodiment, the special positioning of the inner air ring 307 and the outer air ring 306 ensures that cold air is blown to both the inner and outer sides of the negative ion lamp tube 2 for heat dissipation.

[0042] In some embodiments, the lamp holder 1 is electrically connected to the negative ion lamp tube 2, the cooling chip 302 and the micro air pump 3042, wherein the lamp holder 1 is connected in series with the negative ion lamp tube 2, the cooling chip 302 and the micro air pump 3042.

[0043] In this embodiment, the lamp holder 1 is electrically connected to the negative ion lamp tube 2, the cooling chip 302 and the micro air pump 3042. The lamp holder 1 is connected in series with the negative ion lamp tube 2, the cooling chip 302 and the micro air pump 3042 so that when the negative ion energy-saving lamp is powered on, the cooling chip 302 and the micro air pump 3042 work synchronously to dissipate heat from the negative ion lamp tube 2.

[0044] In practical use, the working principle of this utility model is as follows:

[0045] When using this device, first install the negative ion energy-saving lamp into the power-on position using lamp holder 1. After the power is turned on, lamp holder 1 provides synchronous power to the negative ion lamp tube 2, cooling chip 302, and micro air pump 3042, forming a series circuit that works in tandem. After the negative ion lamp tube 2 is turned on, it releases negative ions to purify the air, and the heat generated during its operation is effectively controlled by the heat dissipation and cooling mechanism 3. As the core cooling unit, the cooling chip 302, due to its semiconductor material properties, has its cooling surface facing downwards and closely attached to the inside of the air box 301, rapidly cooling the airflow entering the air box 301 after power is applied. The micro air pump 3042 continuously draws external air into the air box 301 through the air guide bend 3043. The airflow fully contacts the cooling chip 302 within the sealed and insulated air box 301, significantly reducing the temperature and forming a cold airflow. Cold air is diverted through symmetrically distributed guide tubes 305 and enters the outer air ring 306 and inner air ring 307 arranged around the lamp tube. Finally, it is blown at a specific angle onto the inner and outer surfaces of the negative ion lamp tube 2 through the cold air outlets of the annular array, forming a three-dimensional surrounding cooling effect. This design not only ensures that the surface temperature of the lamp tube drops uniformly, but also avoids local heat accumulation through directional airflow, effectively suppressing the risk of material aging or deformation caused by high temperature.

[0046] On the heating side of the cooling element 302, the waste heat generated is rapidly diffused through the wave-shaped heat dissipation fins 303. The heat dissipation fins 303 employ a circumferentially evenly distributed structure design, tightly fitting the outer wall of the air box 301. This, combined with natural convection or ambient airflow, achieves efficient heat dissipation, preventing excessively high heating surface temperatures from affecting cooling efficiency. The air box 301 uses insulating material to isolate internal and external heat exchange, ensuring that the cooling effect of the cooling element 302's cold end is not affected by the external environment, while also preventing energy loss due to heat conduction during cold air transport. The coordinated operation of the outer air ring 306 and the inner air ring 307 ensures precise coverage of the lamp's core heating area with cool air. Combined with the controllable airflow intensity of the micro air pump 3042, the cooling intensity can be dynamically adjusted according to actual operating conditions, reducing energy consumption while ensuring heat dissipation efficiency. The entire system, through thermodynamic and fluid dynamic optimization design, combines active cooling with passive heat dissipation, extending the lamp's lifespan while maintaining the stable operation of the negative ion generator. This completely solves the safety hazards and performance degradation problems caused by insufficient heat dissipation in traditional products.

[0047] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
