TECHNICAL FIELD
[0001] The utility model relates to the field of ball bubble lamp, concretely is a kind of energy-saving LED ball bubble lamp. BACKGROUND
[0002] With the rapid development of semiconductor lighting technology, LED (Light Emitting Diode) ball bubble lamp has gradually replaced traditional incandescent lamp and part energy-saving lamp, and become the mainstream of current lighting market due to its high light efficiency, long service life, energy saving and environmental protection and other advantages. Especially in recent years, in residence, shopping mall, office and industrial plant, the application range of LED ball bubble lamp is continuously expanding, and its market share is also continuously rising. Since LED itself is a temperature-sensitive semiconductor device, too high junction temperature will seriously affect the light emitting efficiency and service life of LED, so the heat dissipation problem has always been one of the most critical factors in the design and manufacturing process of LED lamp. In order to realize the high efficiency work of LED device under the condition of small volume and high brightness, major manufacturers have invested a lot of energy in the heat dissipation structure of LED lamp, and tried various heat dissipation methods and materials to find a balance point between heat dissipation effect and manufacturing cost.
[0003] At present, common LED ball bubble lamp is usually composed of light-transmitting cover, heat sink (or heat dissipation shell), LED chip and driving power supply and other parts.
[0004] With the continuous upgrading of LED technology and the improvement of consumer's quality requirements for lamp, the traditional LED ball bubble lamp gradually exposes some defects in heat dissipation and maintenance:
[0005] Most LED ball bubble lamps use integrally formed or highly integrated heat dissipation shell, and the fins and shell are usually fixed together by pressure casting, welding or mechanical riveting. Although this method can ensure strength and heat dissipation performance to a certain extent, in actual use, the heat dissipation shell or fin is difficult to be disassembled separately. If the lamp works for a long time in outdoor or industrial environment, dust, oil stains or other impurities are easy to accumulate between the internal fins, and the user is difficult to clean the inside of the lamp thoroughly, which leads to the decrease of heat dissipation efficiency, the shortening of LED service life, and even the damage of lamp.
[0006] A considerable part of LED ball bubble lamps pursue light weight and miniaturization, but ignore the later maintenance and repair demand. If LED chip, driving circuit or heat dissipation component has a problem, the lamp can only be replaced as a whole, which increases the maintenance cost and resource waste of user. At the same time, integrated design also leads to that the lamp cannot adjust the number of fins or replace the heat dissipation component with higher heat conduction performance flexibly according to different heat dissipation requirements, and cannot meet the application of multiple scenes and multiple power.
[0007] In environments requiring frequent cleaning (such as restaurant kitchens and factory workshops), most LED bulbs require the power to be disconnected before disassembly, and then the lampshade or outer casing must be forcefully unscrewed. Carelessness in this process can easily damage the internal circuitry or compromise the seal. Furthermore, some light fixtures employ adhesive or potting techniques to enhance their waterproofing, which not only improves waterproofing but also increases the difficulty of subsequent disassembly and reassembly. If users mishandle or forcibly pry them open, it can easily cause short circuits or structural deformation, posing a safety hazard. Utility Model Content
[0008] The purpose of this utility model is to provide an energy-saving LED bulb to solve the technical problems mentioned in the background art.
[0009] Based on the above ideas, this utility model provides the following technical solution:
[0010] Includes a light-transmitting cover, a heat spreader, fins, and an aluminum substrate;
[0011] The heat spreader is disposed on the lower side of the light-transmitting cover. Multiple fins are provided, and the multiple fins are independent of each other. The multiple fins are arranged in a ring array on the lower side of the heat spreader. Each fin is inserted and fixed to the heat spreader. The fins, the heat spreader, and the aluminum substrate form an internal space. The LED bulb ball is disposed in the internal space.
[0012] By placing a heat spreader under the light-transmitting cover and arranging several independent fins in a circular array on its underside, an internal space is formed to accommodate the LED bulb. Because the heat spreader can quickly conduct heat and is interlocked with the fins, it achieves efficient heat diffusion and dissipation, preventing heat buildup in the confined space during LED operation and significantly extending the LED bulb's lifespan. Furthermore, the independent and detachable fins not only facilitate easy disassembly and assembly during later cleaning, preventing dust and impurities from accumulating, but also make the product structure more flexible. The appropriate number and size of fins can be selected according to different power or application requirements, improving the product's versatility and ease of maintenance.
[0013] Preferably, the upper surface of the aluminum substrate is provided with a sliding groove, the bottom of the sliding groove is provided with a fixing groove, and the inner wall of the sliding groove is also provided with a limiting groove horizontally in the middle of both sides.
[0014] The sliding groove is arranged on the upper end surface of the aluminum substrate, and a fixing groove is arranged at the bottom of the sliding groove, and a limiting groove is arranged at the middle position of the inner wall of the sliding groove, so that the positioning and limiting during installation are more accurate and reliable. Through the combined design of the sliding groove and the limiting groove, when the fin and other components are inserted, they can be smoothly introduced in the direction of the sliding groove and limited at the appropriate position; once installed in place, the fixing groove can cooperate with the subsequent fixing part to realize accurate and firm installation. This structure not only facilitates the replacement or disassembly of the fins or other components, but also ensures the overall stability of the heat dissipation structure, thereby effectively improving the assembly efficiency and safety of the LED bulb lamp.
[0015] Preferably, one end of the sliding groove is provided with an elastic member, and the end of the elastic member is provided with a sliding block, and the two sides of the sliding block are fixedly provided with limiting members.
[0016] The elastic member is arranged at one end of the sliding groove, and the sliding block and the limiting member are mounted at the end of the elastic member, which can provide buffering and locking functions when the fin is installed or disassembled. Specifically, when the fin is pushed inward from the outside of the sliding groove, the end of the fin will abut against the sliding block, and after overcoming the elastic force of the elastic member, smooth sliding is realized; and when the fin is positioned in place, the elastic member generates a rebound force to tightly press the fin at the preset position, realizing automatic limiting. As can be seen, the elastic member plays a key role in buffering, shock absorption and tension adjustment, making the fin installation more labor-saving and safe, and effectively avoiding damage or loosening problems that may occur during assembly or disassembly.
[0017] Preferably, the sliding block is slidably arranged in the sliding groove, and the limiting member is in sliding cooperation with the limiting groove.
[0018] The sliding block is slidably arranged in the sliding groove, and the limiting member is in sliding cooperation with the limiting groove, and through this sliding and cooperation relationship, the fixing requirements of the fin in the front and back and up and down directions are further ensured. This not only enables the fin to be accurately guided to the specified position during installation, avoiding assembly errors or structural instability caused by left and right shaking or up and down deviation, but also reduces the influence of vibration and impact on the fin during later operation or use, improving the safety and stability of the overall operation of the LED bulb lamp. Through this structure, the disassembly and assembly of the fin can also be quickly realized, saving manpower and time during subsequent maintenance and cleaning.
[0019] Preferably, the lower side of the fin is provided with a fixing member.
[0020] The fixing member is in limiting cooperation with the fixing groove when the fin is installed on the aluminum substrate.
[0021] The fixing member is added to the lower side of the fin, and during the process of mounting the fin to the aluminum substrate, the fixing member is limitedly matched with the fixing groove of the aluminum substrate, and the fin is firmly combined with the aluminum substrate through clamping or embedding and other ways.When the fin is pressed downward, the fixing member is just clamped into the fixing groove; and under the joint action of the sliding block and the elastic member, the fin is reliably pressed and maintained in the appropriate position. At the same time, the double limiting of the limiting groove and the limiting member can prevent the sliding block from moving up and down, thereby providing more stable support for the installation of the fin. Finally, the goal of fast assembly, firm positioning and simple disassembly in limited space is achieved, the needs of efficient heat dissipation and later maintenance are considered, and the service life and safety performance of the LED bulb lamp are improved.
[0022] Working principle:
[0023] During installation, the fin is placed at the outer end of the sliding groove, one end of the fin abuts against the sliding block, the fin is slid against the elastic force of the elastic member until the fixing member is located at the upper side of the fixing groove, the fin is pressed downward to make the fixing member match with the fixing groove, and due to the limiting action of the limiting groove and the limiting member, the sliding block will not move up and down, and due to the elastic force of the elastic member, the fin is closely connected with the aluminum substrate.
[0024] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0025] By arranging the uniform temperature plate below the light-transmitting cover and inserting a plurality of independent fins in an annular array around the uniform temperature plate, the heat generated during the operation of the LED lamp can be quickly conducted and diffused to prevent excessive concentration of heat. The lamp body temperature is effectively reduced, the performance degradation or damage of components caused by overheating is avoided, and the service life of the LED bulb lamp is prolonged.
[0026] The sliding groove, the fixing groove, the elastic member and the limiting structure (the sliding block, the limiting member and the limiting groove) are designed on the aluminum substrate, and the fin can be quickly assembled or disassembled through simple operations such as insertion, sliding and pressing. The rebound force of the elastic member and the multidimensional limiting of the limiting member jointly act to ensure that the fin is closely combined with the aluminum substrate and is stable and not loose, and the assembly efficiency and safety of the overall structure are improved.
[0027] The independent fin can be disassembled alone, and after disassembly, the fin and the interior of the lamp body can be effectively cleaned to avoid dust accumulation affecting the heat dissipation effect. The modular design facilitates the replacement of fins of different specifications or quantities to meet the differentiated needs for heat dissipation performance in different application scenarios, and improves the flexibility and convenience of maintenance.

[0035] , Figures 1-7 ,
[0036] The energy-saving LED bulb lamp described in the embodiment mainly includes light-transmitting cover 1, uniform temperature plate 2, several fins 3 and aluminum substrate 4.In specific assembly, uniform temperature plate 2 is preferably arranged at the lower side of light-transmitting cover 1, and is stably connected with light-transmitting cover 1 by means such as buckle, thread or gluing, so as to form transition between light source light-emitting area and heat dissipation area.Several fins 3 are designed to be independent of each other and are arranged in annular array and fixed to the lower side of uniform temperature plate 2, that is, the uniform temperature plate 2 is taken as center, and multiple heat dissipation fins are arranged in 360 ° around.Thus, after the heat generated by LED work is evenly dispersed by uniform temperature plate 2, air convection and heat exchange are further strengthened by multiple heat dissipation fins 3, so that heat is rapidly led out and discharged to external environment.
[0037] On this basis, fin 3, uniform temperature plate 2 and aluminum substrate 4 jointly enclose an internal space, which is used for installing LED light-emitting assembly generally including LED lamp bead, driving circuit etc..Among them, aluminum substrate 4 can carry LED chip or lamp bead and be responsible for connecting with external power supply module, at the same time, bear pressure from fin 3 and other heat dissipation components and provide corresponding mechanical support.Through such integrated design, the light-transmitting part and heat dissipation part of lamp body are reasonably separated, which not only guarantees optical performance, but also realizes highly integrated structure form.
[0038] The embodiment further optimizes the specific structure of the aluminum substrate 4, making it perform better in heat dissipation and installation. The aluminum substrate 4 is made of metal material, usually aluminum alloy with good thermal conductivity and certain mechanical strength. A slide groove 6 is opened on the upper end surface of the aluminum substrate 4, which is usually longitudinally or circularly distributed relative to the plane of the aluminum substrate 4. The main function of the slide groove 6 is to provide a guide path for the detachable insertion of the fins 3, so that the fins 3 can be smoothly installed on the aluminum substrate 4.
[0039] At the bottom of the slide groove 6, a fixing groove 8 is opened, which cooperates with the fixing member 5 on the lower side of the fin 3. Once the fin 3 is slid along the slide groove 6 to the predetermined position, the fixing member 5 can be aligned with the fixing groove 8 and clamped or embedded when pressed downward, thereby firmly fixing the fin 3 on the aluminum substrate 4. This can significantly improve the efficiency and stability of the installation.
[0040] In addition, a limiting groove 11 is provided in the middle of the inner wall of the slide groove 6, which matches the limiting member 10 on the fin 3. In specific use, the limiting member 10 can be embedded in the limiting groove 11 during sliding, preventing the fin 3 from shaking left and right or moving significantly during installation and subsequent work, thereby ensuring that the fin 3 can be stably attached between the vapor chamber 2 and the aluminum substrate 4.
[0041] In order to achieve a more flexible and safer installation process, the embodiment provides a resilient member 7 at one end of the slide groove 6, which can usually be a compression spring, an elastic rubber ring or other equivalent elastic structure. The resilient member 7 is located at the end or one side end of the slide groove 6, and is connected with the sliding block 9. When the user inserts the fin 3 into the slide groove 6, the front end of the fin 3 contacts the sliding block 9 and pushes the sliding block 9 to compress the resilient member 7, thereby providing a buffer and rebound space for the entire installation process.
[0042] The sliding block 9 itself can be made of metal or high-hardness plastic material, preferably metal, to ensure structural stability, and limiting members 10 are fixed on both sides. When the end of the fin 3 contacts the sliding block 9, the resilient force of the resilient member 7 needs to be overcome to continue sliding the fin 3 inward. The purpose of this design is:
[0043] When installing the fin 3, the fin 3 can smoothly transition under the action of the elastic force, avoiding potential damage to the components or the aluminum substrate 4 caused by violent impact;
[0044] When the fin 3 reaches the predetermined position, the resilient member 7 pushes the sliding block 9 back, so that the fin 3 is always tightly attached to and closely cooperates with the aluminum substrate 4, solving the problem of looseness or excessive gap;
[0045] The limiting members 10 and the limiting grooves 11 also provide double positioning in the up-down and left-right directions, ensuring that the fin 3 will not shake or even fall off under the action of work vibration or external force.
[0046] Specific installation steps
[0047] Place the aluminum base plate 4 on the assembly workbench and check if there are any impurities in the sliding groove 6 and the fixing groove 8; if there is dust or metal debris, it should be cleaned first to ensure smooth subsequent installation process.
[0048] The elastic member 7 and the sliding block 9 are pre-installed at the end position of the sliding groove 6 of the aluminum base plate 4, and are placed in the corresponding guide rail of the limiting groove 11 through the limiting member 10.
[0049] Take a piece of heat dissipation fin 3, align the lower fixing member 5 of the aluminum base plate 4 with the outer end of the sliding groove 6, and gently push it forward; during the pushing process, the front end of the fin 3 abuts against the sliding block 9 and begins to compress the elastic member 7.
[0050] Once it abuts against the sliding block 9, a moderate force can be applied to overcome the resilience of the elastic member 7, and the fin 3 can be pushed further into the sliding groove 6. During this period, the fin 3 needs to correspond to the insertion position of the heat sink plate 2 to ensure the correct axis and angle. If the fin 3 and the heat sink plate 2 use insertion methods such as bayonet or dovetail structure, the upper part of the fin 3 should be inserted into the clamping groove of the heat sink plate 2 first, and then the action of aligning the sliding groove 6 should be performed.
[0051] When the fin 3 moves above the fixing groove 8, it can be pressed down moderately, so that the lower fixing member 5 of the fin 3 is accurately clamped into the fixing groove 8. At this time, if there is a spring buckle or claw structure, a slight "click" sound will be heard, indicating that it has been installed in place.
[0052] In the above steps, when the fin 3 is in place, the elastic member 7 will push the sliding block 9 back to its original position under the action of its elasticity, so that it continuously adheres to the fin 3, eliminating the possibility of small gaps or shaking between the fin 3 and the aluminum base plate 4.
[0053] At the same time, after the limiting member 10 is fixed on both sides of the sliding block 9, it will continue to be embedded in the limiting groove 11. When external force or slight vibration is encountered, the sliding block 9 will not move up and down obviously, ensuring that the fin 3 is stable and reliable in the overall structure.
[0054] The LED light emitting assembly is usually installed in the middle and upper area of the aluminum base plate 4. After the assembly of the fin 3 is completed, the corresponding LED lamp beads or LED modules can be fixed in advance on the soldering points or screw hole positions reserved on the surface of the aluminum base plate 4.
[0055] The driving power supply can be connected to the back of the aluminum base plate 4, or it can be built-in or external to the ball lamp. Since the focus of this embodiment is on the heat dissipation structure and installation convenience, the electrical connection method can be flexibly selected according to the specific use environment or market demand, such as waterproof drive, adjustable light drive, etc., which can be compatible with this structure.
[0056] The heat-dissipating plate 2 is usually fixed to the inner side of the light-transmitting cover 1 at the beginning of the overall assembly of the lamp, or is combined with the light-transmitting cover 1 into an integrated whole by means of buckling, screwing or other means.
[0057] After the fins 3 and the LED assembly are all installed in place, the light-transmitting cover 1 and the heat-dissipating plate 2 fixed thereto are buckled onto the lamp body as a whole, and finally are attached to the aluminum base plate 4 by screwing or other reliable fixing means. At this time, a closed bulb lamp structure is formed.
[0058] One of the biggest features of the present embodiment is that the fins 3 are of a mutually independent and detachable structure. If more dust or dirt accumulates on the surface of the fins 3 or between the heat-dissipating channels during long-term use, the fins 3 can be quickly cleaned by the following steps:
[0059] The light-transmitting cover 1 and the heat-dissipating plate 2 are removed, exposing the heat-dissipating area where the fins 3 and the aluminum base plate 4 are located.
[0060] The fins 3 are pressed manually or with the aid of a special tool towards the outer end of the sliding groove 6, so that they are separated from the sliding block 9 and disengaged from the fixing groove 8, while attention is paid to maintaining a moderate force to avoid damaging the elastic member 7.
[0061] After the fins 3 are taken out one by one, they are cleaned and wiped with a cleaning cloth, an air gun or a soft brush. If there are stubborn stains or oil stains, a neutral cleaning agent can be used, but attention should be paid to completely drying before reassembling.
[0062] After cleaning is completed, the "fin 3 insertion and assembly" step is repeated, and each fin 3 is inserted into the sliding groove 6 and clamped into the fixing groove 8. Since the aluminum base plate 4 and the fins 3 are of a plug-in structure, disassembly and assembly are extremely simple, greatly improving the efficiency of daily maintenance.
[0063] In order to ensure that the heat-dissipating plate 2 can quickly conduct heat, a metal material with high thermal conductivity, such as copper, aluminum alloy or composite material, is usually selected. If higher thermal conductivity is pursued, a vacuum cavity heat-dissipating plate, which is a form of heat pipe technology, can also be used to greatly improve the heat-dissipating capacity.
[0064] The fins 3 can be made into various forms such as sheet-shaped, corrugated, needle-shaped, etc. to adapt to different heat-dissipating requirements and aesthetic requirements. In the present embodiment, as long as the fins 3 can meet the requirements of plug-in and assembly with the heat-dissipating plate 2, and the requirements of positioning with the aluminum base plate 4 and the sliding groove 6, they are acceptable.
[0065] The number of fins 3 can be customized to increase or decrease according to the power size or heat-dissipating requirements of the LED lamp; for high-power LED lamps, the fins 3 can be densified or thickened; for low-power applications, the number of fins 3 can be reduced to save materials and costs.
[0066] If the heat-dissipating performance is required to be more demanding, a heat-dissipating coating with good thermal conductivity can be applied to the surface of the aluminum base plate 4 or the surface of the fins 3 to reduce the contact thermal resistance and enhance the heat transfer efficiency.
[0067] If the use environment is relatively humid or corrosive, a corrosion-resistant coating or waterproof coating can also be added to the surface of the aluminum substrate 4 and the fins 3 to improve the overall environmental adaptability of the lamp.
[0068] The elastic member 7 is generally selected from metal springs or silicone springs with good fatigue resistance, and it is necessary to ensure that it can maintain stable elastic function in high temperature, vibration and other environments. At the same time, attention should be paid to the matching of its size and elastic coefficient to ensure that it is not too loose or too tight when inserting or removing the fins 3.
[0069] On the basis of the present embodiment, guide rails or lubricating coatings can be added inside the sliding groove 6 to make the fins 3 more smooth when being inserted or removed.
[0070] A buffer pad or spring buckle can also be provided at the bottom of the fixed groove 8 to further enhance the stability and shock absorption of the fins 3, adapting to various high-frequency vibration or impact environments.
[0071] The light-transmitting cover 1 can be made of PC, PMMA or glass, and whether to add anti-glare or diffusion materials can be selected according to the needs to improve the optical lighting effect.
[0072] The present embodiment realizes a high-efficiency heat dissipation path by adding a heat spreader 2 between the light-transmitting cover 1 and the aluminum substrate 4, and arranging a plurality of independently removable fins 3 in a ring array below the heat spreader 2. The heat generated by the LED lamp is first rapidly diffused by the heat spreader 2, and then fully exchanged with the outside air through the fins 3, thereby greatly reducing the temperature rise rate of the LED chip. Compared with traditional ballast lamps using a monolithic heat dissipation structure or simply arranging heat dissipation fins on the surface of the aluminum substrate 4, the heat dissipation efficiency of the present embodiment is higher, and the stable luminous flux output is maintained in long-term use.
[0073] In addition, the present embodiment is particularly optimized in the installation structure, such as the sliding groove 6, the fixed groove 8, the limiting groove 11 on the aluminum substrate 4, and the cooperation of the sliding block 9 and the elastic member 7, which makes the assembly process of the fins 3 simple and user-friendly. Users can complete the insertion or removal of the fins 3 without the help of complex tools. Once the fins 3 are clamped into the fixed groove 8, the elastic member 7 can make the fins 3 tightly fit with the aluminum substrate 4. In combination with the double restraint of the limiting groove 11 and the limiting member 10, the fins 3 can be reliably locked in both horizontal and vertical directions, and even in the case of external vibration, transportation or accidental impact, the fins 3 are not easy to loosen or fall off.
[0074] Meanwhile, the detachable fins 3 greatly facilitate the user to clean and maintain the heat dissipation structure regularly. When the LED bulb is used indoors or outdoors, dust or oil may accumulate, which will affect the heat dissipation effect and shorten the service life of the lamp. By virtue of the split fins 3 of the embodiment, the user can easily detach the fins 3 and clean or replace them individually, so as to effectively keep the heat dissipation channel inside the lamp unobstructed and delay the performance degradation caused by dust accumulation. This modular and easy-to-maintain design concept is not only suitable for household lighting, but also very suitable for industrial and commercial scenes with high environmental requirements and frequent dust removal or disinfection treatment.
[0075] In summary, the specific embodiment combines the excellent heat dissipation performance of the LED bulb with the easy maintenance and service life of the lamp by means of the ingenious and stable mechanical cooperation structure, detachable heat dissipation fins and high-efficiency vapor chamber, which has strong practical value and promotion prospect. Any equivalent replacement or transformation made on the basis of the embodiment shall be deemed to fall within the protection scope of the present application as long as it is within the scope defined in the claims of the present application.
