DETAILED DESCRIPTION

[0022] The technical scheme of the present application will be further described in detail below by means of specific embodiments and in combination with the drawings, and the described embodiments are only part of the embodiments of the present application, but not all the embodiments.

[0023] Embodiment 1: refer to Figures 1 to 4The utility model relates to a high lumen high luminous efficiency bulb structure, one end of lamp stand 1 is connected with the plug -in seat 11, the upper portion of plug -in seat 11 is provided with lamp pin 12, is used for connecting with external power supply and provides stable electrical connection.In the inside of plug -in seat 11, still be provided with the conducting sheet 13, is used for ensuring that the current can smoothly conduct to each component of bulb.The other end of lamp stand 1 is connected with bubble shell 2, and bubble shell 2 is the main light -emitting area of bulb, and the inside is provided with a plurality of lamp strips 3 in parallel, these lamp strips 3 are the core component of bulb light -emitting, through parallel arrangement, can effectively improve the luminous efficiency and brightness of bulb.Bubble shell 2's lower portion still is provided with the aeration column 22, is used for filling in specific gas, to optimize the performance of bulb.

[0024] In the manufacturing process, the LED lamp strip 3 of higher luminous efficiency is encapsulated into bubble shell 2 through spot welding. Then, the aeration sealing operation is carried out, and the gas is filled in the aeration column 22. The filling of the gas can significantly improve the heat dissipation effect of the lamp strip, reduce heat loss, so that the bulb is more easily to reach the target light efficiency. Through this design, the bulb of the utility model can reach the A-level energy efficiency standard, and the service life can reach 50000 hours or even longer, greatly improving the economy and practicability of the bulb.

[0025] In the connection of lamp strip 3, one end of lamp strip 3 is connected with upper lead 31, and upper lead 31 is further connected to conducting sheet 13, so as to realize the conduction of current. Meanwhile, the other end of lamp strip 3 is connected with lower lead 32, and the connection mode of the two ends of the lead ensures that the current can smoothly pass through lamp strip 3, guaranteeing the normal light emission of the bulb. In addition, the inside of lamp stand 1 is also provided with annular limiting groove 14, and bubble shell 2 is clamped into annular limiting groove 14, realizing the stable connection between bubble shell 2 and lamp stand 1. This structural design not only improves the overall stability of the bulb, but also facilitates the assembly and disassembly of the bulb.

[0026] Embodiment 2: refer to Figures 1 to 4 A high lumen high luminous efficiency bulb structure, lamp stand 1 is one of the core components of the whole bulb structure, and one end of lamp stand 1 is connected with plug -in seat 11. The upper portion of plug -in seat 11 is provided with lamp pin 12, and these lamp pins 12 are the key parts of the connection between the bulb and the external power supply, which can ensure that the bulb obtains stable and reliable electrical connection during use, thereby guaranteeing the normal work of the bulb. In the inside of plug -in seat 11, the conducting sheet 13 is also ingeniously arranged. The conducting sheet 13 ensures that the current can smoothly conduct from lamp pin 12 to each component of the bulb, and provides stable power support for the light emission of the bulb.

[0027] The other end of the lamp holder 1 is connected with the bulb shell 2, which is the main light-emitting area of the bulb. Inside the bulb shell 2, a plurality of lamp strips 3 are arranged side by side. These lamp strips 3 are the core components of the bulb for emitting light, and are arranged side by side, which can make the light emitted by the bulb more evenly distributed, thereby effectively improving the light-emitting efficiency and brightness of the bulb, so that it can emit brighter light under the same power. In addition, a gas filling column 22 is specially arranged below the bulb shell 2 for filling with specific gas, and the filling of such gas can further optimize the performance of the bulb, such as improving the heat dissipation effect, etc.

[0028] In the manufacturing process of the bulb, the LED lamp strip 3 with higher light efficiency is first packaged into the bulb shell 2 by spot welding. This packaging method not only ensures the stable installation of the lamp strip 3 in the bulb shell 2, but also guarantees good electrical connection. Then the gas sealing operation is carried out, and specific gas is filled in the gas filling column 22. The filling of such gas can significantly improve the heat dissipation effect of the lamp strip 3, reduce heat loss, so that the bulb is more easily to achieve the target light efficiency. Through this design, the bulb of the utility model can reach the A-level energy efficiency standard, and the service life can reach 50000 hours or even longer, greatly improving the economy and practicality of the bulb, making it have stronger competitiveness in the market.

[0029] In terms of the connection of the lamp strip 3, one end of the lamp strip 3 is connected with the upper lead wire 31, and the upper lead wire 31 is further connected to the lead-through sheet 13, so as to realize the conduction of current from the lamp pin 12 to the lamp strip 3. At the same time, the other end of the lamp strip 3 is connected with the lower lead wire 32, and this two-end lead wire connection method ensures that the current can smoothly pass through the lamp strip 3, guaranteeing the normal light emission of the bulb. In addition, the inside of the lamp holder 1 is also provided with an annular limiting groove 14, and the bulb shell 2 is clamped into the annular limiting groove 14, realizing the stable connection between the bulb shell 2 and the lamp holder 1. This structural design not only improves the overall stability of the bulb, but also facilitates the assembly and disassembly of the bulb, making the bulb more convenient and fast in the production, installation and maintenance process.

[0030] The bulb shell 2 is made of transparent material. This design of transparent shell not only ensures efficient transmission of light, making the light emitted by the bulb brighter and more uniform, but also makes the LED lamp strip 3 inside the bulb visible, increasing the product's appearance and technological sense. The transparent bulb shell 2 is subjected to strict process treatment during manufacturing to ensure its smooth and flawless surface, thereby minimizing the loss of light during transmission and further improving the overall light efficiency of the bulb.

[0031] The lower part of the bulb shell 2 is designed with an arc-shaped end face 21. This arc-shaped structure is not only more aesthetically pleasing but also optimizes the distribution of light. The curvature of the arc-shaped end face 21 is precisely calculated to allow light to be scattered more evenly as it passes through the bulb shell 2, thus preventing light from concentrating in one area and further improving the lighting effect of the bulb. The inflation column 22 is set on the arc-shaped end face 21. This design not only saves space but also makes the connection between the inflation column 22 and the bulb shell 2 more secure, while also facilitating inflation and sealing.

[0032] The thickness at the curved end face 21 is slightly greater than the thickness of the bulb shell 2. This thickness design is carefully considered to enhance the structural strength of the bulb shell 2 at the curved end face 21, preventing deformation or damage to the bulb shell 2 due to inflation or external forces. Simultaneously, the slightly thicker curved end face 21 can better withstand the pressure of the gas inside the inflation column 22, ensuring the stability and safety of the bulb during long-term use. Furthermore, this thickness difference is also designed with the refraction and reflection characteristics of light in mind, further optimizing the bulb's optical performance, enabling it to provide high lumens and high luminous efficacy while maintaining good heat dissipation.

[0033] In the high-lumen, high-efficiency bulb structure of this invention, the light strip 3 uses an advanced LED light strip as the core light-emitting element. As a modern and efficient light-emitting element, the LED light strip has many significant advantages, making it an ideal lighting choice.

[0034] First, LED light strips use high-brightness surface-mount LEDs as their light-emitting elements. These surface-mount LEDs feature pure, soft, and glare-free light, providing high-quality lighting effects. Compared to traditional light sources, LED light strips have extremely high luminous efficiency, converting most electrical energy into light energy, significantly reducing energy waste and achieving high energy efficiency. Furthermore, LED light strips have a very long lifespan, typically reaching 50,000 hours or even longer. This means that under normal operating conditions, the bulbs rarely need to be replaced frequently, greatly reducing maintenance costs.

[0035] LED light strips also feature low-voltage operation, safety and reliability, and waterproof and shockproof characteristics. Low-voltage operation makes the bulbs safer to use, reducing the risk of damage due to voltage fluctuations. The waterproof and shockproof design allows them to operate stably in various complex environments, further improving the bulbs' reliability and durability. These characteristics make LED light strips an ideal choice for high-lumen, high-efficiency bulbs, achieving high brightness while providing energy efficiency and a long lifespan, offering users a more economical, environmentally friendly, and reliable lighting solution.

[0036] The interior of the insertion seat 11 is designed with a lamp pin inner groove 15, and the lamp pin 12 is embedded in the lamp pin inner groove 15. This unique design not only significantly improves the installation stability of the lamp pin 12, but also enhances the overall structural strength of the bulb. The design of the lamp pin inner groove 15 can ensure the stable embedding of the lamp pin 12 in the insertion seat 11. Through this embedded structure, the connection between the lamp pin 12 and the insertion seat 11 is more secure, effectively avoiding the situation that the lamp pin is loose due to external force or vibration. This stable connection mode can ensure the stable electrical connection between the bulb and the external power supply, thereby ensuring that the bulb can continuously and stably emit light during use. In actual use, this structure design can effectively reduce the problem of bulb flickering or not lighting due to poor contact. Stable electrical connection not only improves the reliability of the bulb, but also prolongs the service life of the bulb. By optimizing the installation method of the lamp pin 12, the bulb of the utility model can perform well in various use scenarios, providing users with more stable and reliable lighting experience.

[0037] The inflation column 22 is provided with an inflation port 23, which is a circular opening. This circular opening design has many advantages, making it an ideal choice for inflation operation. The circular opening design is simple in structure and easy to process, which can significantly improve production efficiency. During the inflation process, the circular opening can ensure that the gas flows smoothly into the inflation column 22, and facilitates sealing operation. This design not only improves the inflation efficiency, but also effectively prevents gas leakage, ensuring stable gas pressure inside the bulb. Stable gas pressure is of great significance to optimize the heat dissipation effect of the bulb and prolong the service life.

[0038] By providing a circular inflation port 23 on the inflation column 22, the bulb of the utility model can achieve efficient gas transmission and stable pressure control during the inflation process. This design not only improves the performance and reliability of the bulb, but also provides users with a safer and more efficient lighting product.

The actual measurement can reduce the junction temperature of the light bar by 28℃ (under the same working condition), and the thermal resistance is reduced to 2.5℃ / W.

[0042] The annular limiting groove 14 is designed as a three-stage ladder structure, and the groove depth is 2.5mm, which cooperates with the three 120° distributed flanges at the bottom of the bubble shell to form a labyrinth seal. The contact surface is filled with heat-conducting silicone grease (thermal conductivity 5W / m·K) to establish an axial heat conduction path, and cooperates with an aluminum alloy heat dissipation ring (surface area 380mm 2 ) to realize double-mode heat dissipation.

The test data shows that when the color temperature is 3000K, the color rendering index Ra is greater than 90, the beam angle is 120°, and the center illuminance reaches 1500lx (at a distance of 0.5m).
