[0001] This utility model relates to the field of warning light technology, specifically to an LED warning light, and more particularly to the light-emitting module of the LED warning light, as well as a belt-type LED warning light including the light-emitting module. Background Technology

[0002] LEDs (Light Emitting Diodes) are already very common in our daily lives, with applications mainly in LED displays and LED lighting. LED displays are commonly seen in airports, high-speed rail stations, large stadiums, and large shopping malls, and with technological advancements and cost reductions, large-screen televisions using LED technology will soon be commonplace in ordinary households. LED lighting is also ubiquitous; for example, few homes now use incandescent or fluorescent lamps for lighting, replaced by various LED ceiling lights, LED spotlights, and LED light strips. Flashlights have also almost entirely replaced traditional bulbs with high-power LED chips.

[0003] However, the application of LEDs is not limited to displays and lighting. They have long been used as warning lights, and various LED warning lights are already in use across different scenarios. For example, the applicant's previously filed Chinese utility model patent No. 202223315227.4 is a warning light for power transmission lines. In fact, many scenarios require warning lights, and various warning lights are already in use in many situations. However, existing warning lights have limited application scenarios and are inconvenient to install, thus requiring improvement. Summary of the Invention

[0004] One of the purposes of this utility model is to provide an LED warning light that can be applied to a variety of scenarios and is easy to install, thereby solving the problem that current LED warning lights have limited application scenarios and are inconvenient to install.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An LED warning light is used to be fixed at a suitable position on the outer surface of an object to be warned, thereby emitting warning light when needed. The LED warning light includes a light-emitting module and a fixing component. The light-emitting module is provided with a mounting structure, and the fixing component is a long, thin strip. During installation, the fixing component is connected to the light-emitting module through the mounting structure, and then the fixing component is connected end to end, wrapped around the object to be warned like a belt, thereby fixing the light-emitting module at a suitable position on the outer surface of the object.

[0007] In a preferred embodiment, the fastener is a clamp with a locking head and a slender steel strip, and the installation structure includes a gap or groove that matches the cross-sectional size of the steel strip. After installation, the steel strip passes through the gap or is inserted into the groove.

After installation, the wire, steel rope, or cable tie passes through the round or square hole.

[0009] In a further preferred embodiment, there are two sets of four round or square holes, which are respectively located on the rear side of the light-emitting module near the four corners; and there are two sets of fasteners, which are connected end to end to tighten and fix the device when in use.

[0010] In a further preferred embodiment, the mounting structure includes mounting ribs, which are disposed on the back of the light-emitting module, and the gaps, slots, round holes, or square holes are disposed on the mounting ribs.

[0011] In a preferred embodiment, the light-emitting module includes a housing, and a circuit board, a solar panel, and a battery sealed within the housing. Multiple LEDs are arranged on the outside of the circuit board, and the solar panel and the battery are electrically connected to the circuit board. The housing is transparent at least at the positions corresponding to the solar panel and the LEDs. When there is external light, the solar panel converts light into electrical energy and stores it in the battery. When there is insufficient external light, the circuit board uses the electrical energy in the battery to drive the LEDs to emit warning light.

[0012] In a further preferred embodiment, the circuit board includes a mercury switch, a charging circuit, a control circuit, and the LED light. The charging circuit is electrically connected to the solar panel and the battery, the battery is also electrically connected to the control circuit via the mercury switch, and the control circuit is then electrically connected to the LED light.

[0013] In a further preferred embodiment, the housing includes a front shell and a rear shell, wherein the front shell is made of transparent PC material, and its inner surface is provided with several light-reflecting prisms at least corresponding to the positions of the LED lights.

[0014] In a preferred embodiment, the LED warning light further includes a reflector module, which includes a reflector base and a reflective film attached to the front surface of the reflector base, and the mounting hole is also provided on the rear side of the reflector base.

[0015] The second objective of this utility model is to provide a light-emitting module that is modular and can be used to construct the aforementioned LED warning light, thereby enabling the LED warning light to be applied to various scenarios and to be easy to install.

[0016] A light-emitting module for an LED warning light, wherein the light-emitting module is the aforementioned light-emitting module for an LED warning light.

When in use, it can be easily fixed to a suitable position on the outer surface of objects such as tree trunks, utility poles, street light poles, and cement pillars, just like a belt. It is widely applicable to on-site deployment and warning in industries such as power grids, electricity, railways, highways, and forestry, and therefore has a variety of application scenarios and is easy to install.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0032] Figure 13 This is a circuit diagram of the light-emitting module in an LED warning light according to a specific embodiment of this utility model. Detailed Implementation

[0033] This specific embodiment provides an LED warning light, such as... Figure 1 and Figure 2 As shown, it is used to fix the LED warning light at a suitable position on the outer surface of the object to be warned, such as a tree trunk or utility pole 1, so as to emit a warning light when needed. The LED warning light includes at least one modular light-emitting module 2 and at least one set of fixing members 3. The light-emitting module 2 is provided with a mounting structure 26. The fixing member 3 is a thin strip. During installation, the fixing member 3 passes through the mounting structure 26, and then the fixing member 3 is wrapped around the object to be warned like a belt and connected end to end, so that the light-emitting module 2 is fixed at a suitable position on the outer surface of the utility pole 1 to be warned.

[0034] The LED warning light employing the light-emitting module 2 of this utility model's specific embodiment utilizes modular light-emitting modules 2 combined with slender strip-shaped fixing parts 3 to form a belt-like LED warning light. In use, it can be easily fixed to suitable positions on the outer surface of objects such as tree trunks, utility poles 1, streetlight poles, and cement pillars, making it widely applicable for on-site deployment and warning in industries such as power grids, electricity, railways, highways, and forestry. Furthermore, the type and length of fixing parts can be selected according to needs, as can the appropriate number of light-emitting modules 2, resulting in diverse application scenarios and convenient installation.

[0035] In a specific embodiment of this utility model, a preferred embodiment is adopted that has a lock head 31 and a slender steel strip 32. Figure 2 The clamp (not fully drawn in the middle steel strip) serves as the fixing component 3. The mounting structure 26 includes a gap 261 that matches the cross-sectional dimensions of the steel strip 32. Furthermore, according to site requirements, a single steel strip 32 is used to fix six light-emitting modules 2 and six reflective modules 4 in two groups to opposite sides of the utility pole 1, thereby achieving a warning over a wide angle range of more than 120 degrees on both opposite sides of the utility pole 1.

[0036] In this specific embodiment, the fixing component 3 is a clamp with a locking head 31 and a steel band 32, but it is understood that wire, steel rope, or cable ties can also be used. The installation structure 26 is as follows: Figure 3 The diagram also includes round holes 262 or rectangular holes (rectangular holes are not shown in the figure because round holes 262 can also be used to fit cable ties) adapted to the cross-sectional dimensions of the wire, steel rope, or cable tie. Because the steel strap 32 of the clamp usually has certain specifications, it is difficult to meet certain special situations, while wire and steel rope can be cut to suitable lengths as needed, thus having a wider range of applications. Cable ties are convenient to use and inexpensive, but cannot maintain reliability for a long time, and are suitable for short-term temporary warning scenarios. Although a clamp is used in this specific embodiment, as... Figure 3 As shown, in addition to the slot 261 for the steel strip 32 to pass through, there is also a round hole 262 for the wire or steel rope to pass through. These can be used flexibly according to the site conditions. During installation, ensure the steel strip 32 is flattened, with the clamp head 31 protruding towards the light-emitting side, so that the steel strip 32 passes through the slot 261 of the light-emitting module 2 and the slot 461 of the reflective module 4 mounting structure 46. Note the orientation of the light-emitting module 2 during installation; it is best to place the battery compartment 27 downwards.

[0037] In further preferred technical solutions, such as Figure 3 and Figure 4 As shown, there are four circular holes 262 and 462 in two sets, respectively located near the four corners on the rear side of the light-emitting module 2 and the reflective module 4; and there are two sets of fixing members 3. In use, each set of fixing members 3 passes through the two circular holes 262 of each light-emitting module 2 and the two circular holes 462 of the mounting structure 46 of the reflective module 4, and then they are connected end to end to tighten and fix. If a clamp is used, because its steel strip 32 has a certain width, usually only one set is needed for reliable fixing. However, if iron wire, steel rope, or cable ties are used, two sets are needed for a more secure and reliable fixation.

[0038] In a preferred embodiment, the light-emitting module 2 is as follows: Figures 3 to 8 As shown, it includes a housing 20, and a circuit board 22, a solar panel 23, and a battery 24 sealed within the housing 20; a photosensitive element and multiple LED lights 222 are disposed on the outer side of the circuit board 22. Figure 13As shown, both the solar panel 23 and the battery 24 are electrically connected to the circuit board 22, which in turn is electrically connected to the LED light 222. The housing 20 is transparent at least at the locations corresponding to the solar panel 24, the LED light 222, and the photosensitive element. When there is external sunlight, the solar panel 23 converts light into electrical energy and stores it in the battery 24. When the photosensitive element detects insufficient external light, the circuit board 22 uses the electrical energy from the battery 24 to drive the LED light 222 to emit a flashing warning light. The solar panel 23 uses a high-efficiency monocrystalline silicon thin-film solar cell; the built-in battery 24 uses an 18650 lithium-ion battery, which is high-energy, memory-free, pollution-free, high-capacity, long-life, safe and stable, with a low self-discharge rate and a cycle life of over 1000 times; the LED light 222 uses a high-brightness, brand-name LED with a strobe working mode and a flashing visibility distance of up to 800 meters; the circuit board 22 has a photosensitive element to achieve intelligent light control switch control, allowing the light to be turned off during the day for solar energy storage and automatically flashing at night for warning. The photosensitive element can be a component such as a photoresistor. In this specific embodiment, the photosensitive element is a solar panel 23. The control circuit determines the intensity of external light by detecting the voltage output of the solar panel 23, thereby controlling the LED light 222. At this time, the solar panel 24 is also directly electrically connected to the circuit board 22.

[0039] In the preferred technical solution, such as Figure 13 As shown, the circuit board 22 includes a mercury switch, a charging circuit, a control circuit, and the LED light 222. The charging circuit is electrically connected to the solar panel 23 and the battery 24. The battery 24 is also electrically connected to the control circuit via the mercury switch, and the control circuit is in turn electrically connected to the LED light 222. During the day, under sunlight, the solar panel 24 charges the battery 24 through the charging circuit. When there is insufficient light, such as at night, the battery 24 drives the LED light 222 to emit a warning light through the control circuit. The mercury switch is fully enclosed and mounted on the control board at a 30° angle. During transportation and storage, the light-emitting module is usually placed horizontally. In this case, the conductive silver beads inside the mercury switch do not contact the conductive pins on both sides, the mercury switch is in an open state, and the control circuit does not work. When the light-emitting module is correctly installed, the circuit board is generally perpendicular to the ground. In this case, the conductive silver beads inside the mercury switch contact the conductive pins on both sides, the mercury switch is in an on state, and the control circuit works normally. The LED warning light using the light-emitting module of the specific embodiment of this utility model uses a mercury switch, eliminating the need for manual switch control and achieving simple operation and energy saving; moreover, it eliminates the need for a separate switch on the product casing, better ensuring the product's waterproofness and consistent appearance.

[0040] In the preferred technical solution, such as Figures 6 to 8 As shown, the housing 20 includes a front housing 201 and a rear housing 202, wherein the front housing 201 is made of transparent PC material, and as shown... Figure 9 As shown, the inner surface of the device has several light-reflecting prisms 2011 at least corresponding to the positions of the LED lights 222. The light-reflecting prisms 2011 further diffuse the light emitted by the LED lights 222, and through continuous refraction of the prism faces, the light produces a larger illumination area and higher transmittance, thus providing a more conspicuous warning effect in harsh weather conditions. The light-reflecting prisms 2011 are located on the inner side rather than the outer side, which effectively prevents dust accumulation, keeps the outer surface smooth, and ensures consistent light output. The front shell 201 is made of transparent high-quality PC material, which can withstand long-term exposure to sunlight, is resistant to aging, has good light transmittance, and is impact-resistant. The rear shell 202 is injection molded from ABS raw materials that are anti-aging, wear-resistant, and highly transparent.

[0041] In addition, such as Figures 6 to 8 As shown, a groove is provided on the contact surface where the front shell 201 and the rear shell 202 are fastened. When the front shell 201 and the rear shell 202 are locked together by the screw 5, the sealing ring 6 in the groove is pressed, so that the front shell 21 and the rear shell 22 are tightly fastened to form a sealed shell 20 with good waterproof performance, which can withstand long-term exposure to sunlight and rain.

[0042] In a preferred embodiment, the back of the housing 20, i.e., the back of the rear housing 22, is provided with mounting ribs 260. The mounting structure 26 includes the mounting ribs 260, as well as slots 261 and round holes 262 provided on the mounting ribs 260. The mounting structure 26 is integrally formed with the rear housing 22. It is understood that the mounting structure 26 can have other forms, all of which should be within the protection scope of this utility model. For example, a square ring can extend directly outward from the rear housing for the steel strip 32 to pass through. Alternatively, a circular ring can extend directly outward from the thick housing for the wire, steel rope, or cable tie to pass through. Two figure-7 shaped structures can also extend outward from the rear housing, with the two figure-7 shaped structures facing each other, thus forming a slot between them, which can also allow the steel strip 32 to pass through, achieving a similar effect. If the size is appropriately adjusted, installation can not only be done by passing through but also by snapping in, making installation more convenient when the steel strip is very long.

[0043] In this specific embodiment, to make the light-emitting module 2 thinner and lighter, and due to the size limitations of the battery 24, the battery compartment 27 has to protrude from the plane of the rear shell 202. The mounting rib 260 allows the position of the fixing member 3 to be moved back, avoiding uneven mounting surfaces or even damage to the battery compartment 27 due to pressure. Moreover, the mounting rib 260 not only provides a better mechanical structure, but also has sufficient size to accommodate the fixing member 3. In this specific embodiment, each mounting rib 260 has a slot 261 in the middle for a steel strip to pass through, and a circular hole 262 above and below the slot 261 for a wire or steel rope to pass through.

[0044] In the preferred technical solution, such as Figure 1 and Figure 2 As shown, the LED warning light also includes a reflector module 4, the reflector module 4 as follows: Figure 10 and Figure 11 The image shows a reflector base 40 and a reflective film 41 attached to the front surface of the reflector base 40. The mounting structure 46 is also provided on the rear side of the reflector base 40. The mounting structure 46 also includes a mounting rib 460 and a slot 461 and a round hole 462 provided on the mounting rib 460. The mounting rib 460, slot 461, and round hole 462 are integrally formed with the reflector base 40.

[0045] To further expand the application scenarios, in this specific embodiment, the reflective module 4 is as follows: Figure 12 As shown, multiple screw posts 47 are provided on the rear side, and the rear side of the light-emitting module 2 is as follows: Figure 2 and Figure 3 The device is equipped with a slot 25, allowing for screw fixing. When installing the light-emitting module 2, the additional mounting plate needs to be screwed into a suitable position on the surface of the object to be warned. Then, align the slot 25 on the back of the light-emitting module 2 with the rib of the mounting plate, and push it upwards until the mounting plate is flush with the top surface of the light-emitting module 2. At this point, the spring clip engages and locks in place. The reflector base 40 of the reflector module 4 is as follows... Figure 11 As shown, screw holes are provided at the four corners, allowing for self-fixation with screws without the need for a separate mounting plate. The number of light-emitting modules 2 and reflective modules 4 can be selected as needed, allowing for the creation of various desired patterns.

[0046] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
