Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead technology, and in particular to an LED lamp bead that protects against blue light hazards. Background Technology

[0002] LED chips, as a widely used light source in the lighting field, play an important role in many scenarios. The light-emitting principle of LED chips is based on the electron transitions in semiconductor materials, which are driven by electric current to emit light. In practical applications, LED chips typically need to possess the following characteristics:

[0003] 1. The LED beads have high luminous efficiency, enabling them to produce bright and stable light while consuming relatively little power;

[0004] 2. The lamp cover has good heat dissipation performance to ensure that the lamp beads will not be damaged due to overheating during operation.

[0005] Currently, manufacturers employ various technologies and methods to achieve optimal performance and application effects for LED chips. Some manufacturers improve the luminous efficiency and stability of LED chips by optimizing chip design and packaging processes during manufacturing; others improve the driving circuitry to better control the current and voltage; and still others invest heavily in the heat dissipation structure design to ensure the chips maintain a suitable temperature during operation.

[0006] However, LED chips face some challenges in practical applications. Regarding blue light protection, some chips offer limited protection, still exhibiting blue light leakage, which may pose a threat to human health, such as eye fatigue and decreased vision. In terms of pin protection, the chip pins are susceptible to external forces during production, installation, and use, leading to pin breakage. This not only affects the electrical connection of the chip but may also reduce its lifespan. This application addresses these issues by proposing a solution: designing an LED chip with both blue light protection and pin protection functions. This chip effectively reduces blue light leakage while protecting the pins from external damage, improving the chip's stability and lifespan. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides an LED bead that protects against blue light hazards. It solves the problem that some LED beads have limited blue light protection effects and still have blue light leakage, which may pose a certain threat to human health. Furthermore, the LED bead pins are easily affected by external forces during production, installation, and use, leading to pin breakage.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An LED bead for preventing blue light hazards includes a bead body, a set of pins fixedly connected to the lower surface of the bead body, a protective cover for protection on the annular side of the bead body, a set of protective sleeves for limiting position below the protective cover, two magnetic blocks fixedly connected between the set of protective sleeves, two sets of arc-shaped sleeves for protection below the set of protective sleeves, a set of grooves formed on the inner wall of the protective cover, and the protective cover is made of polymethyl methacrylate, which has excellent transparency, high surface hardness, and good wear resistance.

[0010] Preferably, a connecting ring is fixedly connected to the annular side of the lamp bead body, and two brackets are fixedly connected to the lower surface of the connecting ring. The protective sleeves located on the left and right sides of the set of protective sleeves are fixedly connected to the two brackets respectively. A set of grooves is opened on the inner wall of the protective sleeve, making its inner wall uneven, so as to reflect and refract the light beam emitted by the lamp bead body, so that the light passes through multiple propagations and mixing inside, reducing the direct emission of blue light.

[0011] Preferably, two pairs of connecting plates are fixedly connected between the two sets of arc-shaped sleeves, and a magnetic block two is fixedly connected to the upper surface of each connecting plate. The two pairs of magnetic blocks two are magnetically fixed to two magnetic blocks one respectively. By protecting a set of pins, their service life is improved, the stability of the lamp body during use is ensured, and the maintenance and replacement costs are reduced.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The protective cover is made of polymethyl methacrylate, which has excellent transparency, high surface hardness, and good wear resistance. Its surface is coated with a multi-layer optical film that blocks blue light. It uses the principle of thin film interference to reflect blue light. In addition, a set of grooves are opened on the inner wall of the protective cover, making its inner wall uneven. This reflects and refracts the light beam emitted by the lamp body, so that the light passes through multiple times and mixes inside, reducing the direct emission of blue light and improving the uniformity and spectral quality of the light.

[0014] 2. A set of protective sleeves is provided on the surface of a set of pins for protection. The set of protective sleeves is connected by two magnetic blocks and fixed by two brackets. The two sets of arc-shaped sleeves are magnetically fixed by magnetic blocks and interlocked with each other, further protecting the set of pins.

[0024] A connecting ring 3 is fixedly connected to the annular side of the lamp bead body 1. Two brackets 4 are fixedly connected to the lower surface of the connecting ring 3. The protective sleeves 5 on the left and right sides of a set of protective sleeves 5 are fixedly connected to the two brackets 4 respectively.

[0025] Among them, the lamp bead body 1 is the core part of the LED lamp bead, which emits light by being driven by current based on the electronic transition of semiconductor materials, and the pins 11 on its lower surface are used to realize electrical connection.

[0026] The protective cover 2 is made of polymethyl methacrylate, which has good transparency, high hardness, and good wear resistance. The surface is coated with multiple optical films to reflect blue light using the principle of thin film interference. The inner wall groove 7 reduces the direct emission of blue light by reflecting and refracting light, thereby improving light uniformity and spectral quality. It is used to protect the lamp bead body 1.

[0027] The connecting ring 3 is fixed to the annular side of the lamp bead body 1, serving to connect and support related components;

[0028] The bracket 4 is connected to the lower surface of the connecting ring 3 to fix the protective sleeve 5 and to support the protective structure.

[0036] Working principle:

[0037] The protective cover 2 is made of polymethyl methacrylate, which has excellent transparency, high surface hardness, and good wear resistance. Its surface is coated with a multi-layer optical film that blocks blue light. It reflects blue light using the principle of thin-film interference. The inner wall of the protective cover 2 has a set of grooves 7, making its inner wall uneven. This reflects and refracts the light beam emitted by the lamp bead body 1, causing the light to propagate and mix multiple times inside, reducing the direct emission of blue light and improving the uniformity and spectral quality of the light. A set of protective sleeves 5 are provided on the surface of a set of pins 11 for protection. The set of protective sleeves 5 is connected by two magnetic blocks 8 and fixed by two brackets 4. Two sets of arc-shaped sleeves 6 are magnetically fixed by magnetic blocks 9 and interlocked with each other, further protecting the set of pins 11.
