Description

Technical Field

[0001] This utility model relates to a light bulb and belongs to the technical field of lighting appliances. Background Technology

[0002] In the field of lighting fixtures, the most widely used light bulbs on the market are LED bulbs and incandescent bulbs. They play an important role in many scenarios such as daily life and industrial production, but they also have some significant shortcomings in use.

[0003] LED bulbs, as a relatively advanced lighting device, work by directly converting electrical energy into light energy through semiconductor chips. Typically, a large number of LED chips are needed to achieve a uniform light source. However, LED bulbs have certain drawbacks. On the one hand, the light from LED bulbs is generally quite glaring, which can easily cause discomfort to the eyes during prolonged use. On the other hand, the high brightness of LED bulbs is mainly concentrated at the direct viewing angle; when the observer moves away from this angle, the light rapidly attenuates, which to some extent limits the uniformity and coverage of the illumination.

[0004] Incandescent light bulbs are a traditional type of lighting fixture. They rely on an electric current passing through a tungsten filament to generate high heat, heating the filament to incandescence and emitting visible light through thermal radiation. However, incandescent bulbs have significant drawbacks. First, they produce a large amount of heat radiation, which not only wastes energy but also poses safety hazards during use, such as causing fires. Second, the light from incandescent bulbs is also quite glaring, making it unsuitable for comfortable lighting over extended periods. Furthermore, from an environmental perspective, the production of incandescent bulbs emits greenhouse gases, negatively impacting the environment. Moreover, discarded incandescent bulbs contain trace amounts of heavy metals such as mercury and lead; if not properly disposed of, these heavy metals can enter soil and water sources, causing environmental pollution and harming ecological balance and human health.

[0005] In summary, existing LED and incandescent bulbs have numerous problems in terms of heat radiation, light softness, illumination uniformity, and environmental impact. Therefore, it is necessary to make corresponding improvements to meet people's needs. Utility Model Content

[0006] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a light bulb.

[0007] The technical solution of this utility model is as follows:

[0008] A light bulb includes a bulb holder and a bulb body. The bulb holder is located above the bulb body. A connecting groove is formed inward at the bottom of the bulb holder. An internal connecting thread is formed on the side wall of the connecting groove. An LED light panel with LED beads facing the bulb body is also set in the connecting groove. The bulb body is made of acrylic material and has a solid frustum structure inside. The diameter of the top of the bulb body is smaller than the diameter of the bottom of the bulb body, and the bottom of the bulb body is also arc-shaped. A connecting thread tube is provided on the top of the bulb body for threaded connection with the internal connecting thread to be connected into the connecting groove. Several thin strips are formed inside the bulb body extending from the top of the bulb body to the center of the bottom of the bulb body.

[0009] The length of the connecting threaded tube is set to ensure that it will not interfere with the LED light board when it is connected into the connecting groove.

[0010] The thin strips are arranged in a circular array inside the lamp body with the center line of the lamp body as the array center.

[0011] The thin strips are arranged along the axial direction of the lamp body inside the lamp body, following the outline of the lamp body.

[0012] The lamp head has a conductive contact on its top, which is electrically connected to the LED light board. An external thread is provided on the outer side wall of the lamp head near the top.

[0013] This utility model has the following beneficial effects:

[0014] This invention firstly uses acrylic material to make the lamp body. Acrylic material has good light transmittance, weather resistance, stability, and recyclability. Its optical clarity allows for better transmission of the patterns inside the lamp body. Its weather resistance, stability, and recyclability also ensure that the bulb produces almost no pollutants during production, use, and disposal, making it highly environmentally friendly. Secondly, the lamp body is designed as a truncated cone structure, smaller at the top and larger at the bottom, to better absorb the light emitted by the LED panel, ensuring a good luminous effect. Thirdly, the bottom of the lamp body is designed in an arc shape to make the emitted light more uniform and softer, and to expand the illumination range of the bulb. Finally, several thin strips are cut inside the lamp body. These strips disrupt the original straight-line propagation path of the light emitted by the LED panel, causing the light to scatter and diffuse, thereby evenly dispersing the concentrated light into the surrounding space, ensuring uniform illumination and coverage. Compared with existing technologies, the bulb formed by the acrylic lamp body and LED panel has the advantages of low heat radiation, soft and uniform emitted light, large illumination range, and high environmental friendliness.

[0018] 1. Lamp holder; 2. Lamp body; 3. Connecting groove; 4. Connecting internal thread; 5. LED light board; 6. Connecting threaded tube; 7. Thin strip; 8. Conductive contact; 9. Mounting external thread. Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Example: Please refer to Figure 1 and Figure 2 This embodiment provides a light bulb, including a lamp holder 1 and a lamp body 2. The lamp holder 1 is disposed above the lamp body 2. The lamp holder 1 is made of PBT material, which has the characteristics of high temperature resistance, good electrical insulation, and excellent flame retardant properties. As the material of the lamp holder 1, it better avoids spontaneous combustion and leakage during use, thus ensuring good safety of the light bulb. In the design of the lamp holder 1, its upper part can be slightly narrower than its lower part to facilitate connection to an external power source. The top of the lamp holder 1 is provided with a conductive contact 8 made of high-purity copper metal to ensure good conductivity and corrosion resistance. The outer wall of the lamp holder 1 near the top is provided with an external mounting thread 9, which can be wrapped with aluminum metal. The external mounting thread 9 is used to connect with the lamp holder of the external power source, and the wrapped aluminum metal gives the lamp holder 1 good corrosion resistance. The bottom of the lamp holder 1 has a connecting groove 3, and the side wall of the connecting groove 3 has a connecting internal thread 4. The connecting groove 3 also has an LED light board 5 with the lamp beads facing the lamp body 2. The LED light board 5 is fixedly installed on the bottom wall of the connecting groove 3, and the LED light board 5 is also electrically connected to the conductive contact 8 so that it can be connected to an external power source.

[0021] The lamp body 2 is made of acrylic material, which has excellent light transmittance, weather resistance, stability, and recyclability. Its optical clarity allows for better transmission of the internal patterns within the lamp body 2. Its weather resistance, stability, and recyclability also ensure that this bulb produces virtually no pollutants during production, use, and disposal, making it highly environmentally friendly. The lamp body 2 has a solid internal frustum structure, specifically, the diameter of the top of the lamp body 2 is smaller than the diameter of the bottom. This top-smaller-bottom-larger frustum structure allows for better absorption of light emitted from the LED panel 5, ensuring optimal luminous effect. The bottom of the lamp body 2 is also rounded, which makes the light emitted by the lamp body 2 more uniform and softer, and expands the illumination range of the bulb. The top of the lamp body 2 is provided with a threaded connecting tube 6 for threaded connection with the internal connecting thread 4, allowing it to be connected into the connecting groove 3. The lamp body 2 can be connected to the lamp head 1 through the threaded connection of the threaded connecting tube 6 and the internal connecting thread 4. The length of the threaded connecting tube 6 is set to ensure that it does not interfere with the LED light board 5 when connected into the connecting groove 3, thus not affecting the operation and status of the LED light board 5. After the lamp body 2 and the lamp head 1 are connected, the light emitted by the LED light board 5 can then be projected onto the lamp body 2 through the threaded connecting tube 6 and emitted outwards through the lamp body 2.

[0022] The lamp body 2 also has several thin strips 7 extending from the top of the lamp body 2 to the center of the bottom of the lamp body 2. The specific number and width of the thin strips 7 can be selected according to the specific size of the lamp body 2, and are not limited here. The preferred number of thin strips 7 is 18 to 36, and the preferred width of the thin strips 7 is 0.8 to 2 mm. The thin strips 7 are arranged in a circular array inside the lamp body 2 with the center line of the lamp body 2 as the array center. The thin strips 7 are arranged along the axial direction of the lamp body 2 and follow the outline of the lamp body 2 so that the shape formed by all the thin strips 7 is similar to the lamp body 2. The arrangement of the thin strips 7 can disrupt the original straight propagation path of the light emitted by the LED light panel 5, causing the light to scatter and diffuse, thereby dispersing the concentrated light evenly into the surrounding space, ensuring the uniformity of lighting and coverage.

[0023] The specific processing method for the thin strip 7 can be selected according to the actual situation. In this embodiment, the thin strip 7 is processed using the existing laser engraving technology. A high-energy laser beam is used to engrave the desired pattern inside the lamp body 2. Before laser engraving, the surface of the lamp body 2 needs to be cleaned with a special acrylic cleaner, and then the lamp body 2 is fixed using a vacuum clamp to avoid dust and vibration affecting the engraving. The laser engraving parameters can be set as follows: the laser output power is set to 70W, with nitrogen protection to ensure the engraving depth while avoiding melting or burning. A high frequency of 220Hz is used for denser light spots, and the speed is set to 200mm / s to avoid discontinuous engraving lines due to excessive speed, thus improving engraving accuracy. A fill spacing of 0.05 is set to increase the fill density and deepen the engraving effect.

[0024] In actual use, other desired patterns can be customized inside the lamp body 2, such as bubble type, teardrop type, crack type, etc., to achieve the desired decorative effect.

[0025] In this embodiment, the lamp head 1 and the lamp body 2 are first connected together by connecting the threaded tube 6 and the internal thread 4. Then, the lamp head 1 is installed in the lamp holder of the external power supply by installing the external thread 9. At this time, the conductive contact 8 can draw power from the external power supply so that the LED light board 5 can work and emit light.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
