Description

Technical Field

[0001] This utility model relates to the field of mining lamp technology, and in particular to a mine lamp. Background Technology

[0002] Currently, most mining lamps used in the Chinese market are lead-acid battery lamps. The battery and lamp head are connected by a cable, with all three components exposed. The biggest drawback is the susceptibility to electrical sparks generated by collisions, drops, cable damage, or breakage of the battery and lamp head, potentially leading to gas explosions. This is the root cause of mining accidents caused by mining lamps. my country has millions of coal miners with relatively low levels of education and weak safety awareness. Violations of regulations regarding the use of mining lamps include: replacing broken bulbs underground without authorization, or dropping the lamp head, all of which easily cause electrical sparks and lead to mining accidents. Furthermore, my country has a large mining workforce, and mining lamps are consumables. Current mining lamp production technology is mature, and market competition is fierce. In order to reduce costs, some manufacturers have resorted to various tricks, which is reflected in the fact that the ex-factory price of an ordinary lead-acid battery mining lamp is between 40 and 100 yuan. The huge price difference comes at the cost of safety hazards. Therefore, traditional mining lamps have obvious structural defects and cannot be used in harsh environments, such as high and low temperatures, old open areas with water accumulation, etc. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a mine lamp.

[0004] The present invention provides a mine lamp comprising:

[0005] The lampshade has a hollow internal structure;

[0006] The lamp holder is sealed inside the hollow structure, with its outer surface in contact with the inner surface of the hollow structure. One of the outer surfaces of the lamp holder has a wire groove extending along its length and at least one mounting groove. The mounting groove is used to install multiple light-emitting elements arranged at equal intervals. The wire groove is used to accommodate cables and install power supplies. The lamp cover has a transparent area, which corresponds to the position of the mounting groove.

[0007] Preferably, the light-emitting element is a light strip or light bar.

[0008] Preferably, the mounting groove is a U-shaped groove, and the light strip or light bar is fixed to the bottom wall of the U-shaped groove.

[0009] Preferably, the mounting groove is a trapezoidal groove that is wider at the outside and narrower at the inside along the direction from the outside to the inside of the lamp holder, and the lamp strip or light bar is fixed to the outer wall of the two sides and the outer wall of the inner top surface of the trapezoidal groove.

[0010] Preferably, the lampshade is further provided with a notch, and the notch is used to install a heat sink.

[0011] Preferably, the heat sink is rectangular or dovetail-shaped.

[0012] Preferably, the lampshade is a cuboid structure, the lamp holder is a cuboid heat dissipation profile, and at least 40% of the outer surface of the heat dissipation profile is in contact with the inner surface of the hollow structure.

[0013] Preferably, the lampshade is made of polycarbonate.

[0014] In summary, this utility model has the following beneficial effects: by placing the light-emitting element, cable, and power supply inside the lamp holder, and sealing the lamp holder inside the lamp cover so that none of them are exposed, and by eliminating the use of external cables, it eliminates the possibility of electric sparks caused by collisions, drops, cable damage, or breakage between the battery and the mine lamp head. It also has explosion-proof and waterproof characteristics, and makes it inconvenient for miners to disassemble the mine lamp strip underground, thus avoiding mining accidents caused by unauthorized replacement of bulbs underground.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] like Figure 1-4 As shown, this embodiment of a mine lamp includes:

[0026] Lampshade 1, with a hollow structure 11 inside;

[0027] The lamp holder 2 is sealed inside the hollow structure 11, with its outer surface contacting and fitting the inner surface of the hollow structure 11. One outer surface of the lamp holder 2 has a wire groove 22 extending along its length and at least one mounting groove 21. The mounting groove 21 is used to mount multiple equidistantly arranged light-emitting elements 3. The wire groove 22 is used to accommodate cables 4 and mount a power supply 5. The lampshade 1 has a transparent area corresponding to the mounting groove 21, facilitating the transmission of light from the light-emitting elements and ensuring the lighting effect. The specific number of mounting grooves 21 depends on the actual lighting requirements.

[0028] The light-emitting element 3 is connected to the power supply 5 via cable 4, and the power supply 5 can be a battery or the like.

[0029] It should be noted that the height of the light-emitting component 3 after installation is lower than the depth of the mounting groove 21, and the height of the cable 4 after installation is lower than the depth of the cable groove 22.

[0030] In this way, by placing the light-emitting element 3, cable 4, and power supply 5 inside the lamp holder 2, and sealing the lamp holder 2 inside the lamp cover 1, none of them are exposed. Without using external cables, the electrical sparks caused by collisions, drops, cable damage, or breakage between the battery and the mine lamp head are eliminated. It has explosion-proof and waterproof characteristics, and makes it inconvenient for miners to disassemble the mine lamp strip underground. When the battery power is exhausted, the entire mine lamp can be directly replaced with a new one, avoiding mining accidents caused by unauthorized replacement of light bulbs underground.

[0031] Furthermore, the light-emitting element 2 is configured as a light strip or light bar.

[0032] Furthermore, the lampshade 1 is designed as a cuboid structure, and the lamp holder 2 is designed as a cuboid heat dissipation profile, making the mine lamp in this embodiment suitable for use in harsh environments such as high and low temperatures.

[0033] At least 40% of the outer surface of the heat dissipation profile is in contact with the inner surface of the hollow structure 11. This ensures a tight connection, preventing the lamp holder 2 from easily wobbling within the lamp cover 1, thus improving stability and enhancing the safety of the mining lamp lighting.

[0034] In the preferred solution, such as Figure 4 As shown, the lampshade 1 also has a notch 6, which is used to install a heat sink 7. Specifically, the heat sink 7 is rectangular or dovetail-shaped. By dissipating the heat generated by the light strip or light belt to the external environment of the lampshade 1, the heat dissipation effect is further improved.

[0035] Example 1: As Figure 1 and Figure 2 As shown:

[0036] The mounting slot 21 is a U-shaped slot 211, and the light strip or light bar is fixed to the bottom wall of the U-shaped slot 211.

[0037] Example 2: Figure 3 As shown:

[0038] The mounting groove 21 is a trapezoidal groove 212 that is wider at the outside and narrower at the inside along the lamp holder 2 from the outside to the inside. The light strip or light bar is fixed to the outer wall of the two sides and the outer wall of the inner top surface of the trapezoidal groove 212.

[0039] In this way, while ensuring that the lamp holder 2 and the lamp cover 1 of the heat dissipation profile have a large contact area, the mounting groove contains a large number of lamp strips or light strips.

[0040] Of course, in other embodiments, the mounting slot 21 can also be set to other shapes, without specific limitations, depending on the actual situation.

[0041] In this embodiment, the lampshade 1 is made of polycarbonate, which has the advantages of good light transmission, light weight, high strength and adaptability to various downhole environments.
