Description

Technical Field

[0001] The utility model relates to the technical field of special light sources, in particular to a light-guiding lighting device. Background Art

[0002] In areas with flammable and explosive, high humidity, high salt content, and high corrosive gases such as waste incineration power plants, sewage treatment plants, and oil depots, the existing explosion-proof lighting system cannot fundamentally eliminate the risk of electric sparks. If electrical equipment is installed in such dangerous places, there is a risk of being ignited by electric sparks, and the service life of ordinary explosion-proof lighting fixtures cannot be guaranteed in such harsh environments. Existing patents tend to be complex in structure and do not consider the impact of high temperature generated by the light source on the optical fiber. For example, Chinese patents with announcement numbers CN216052288U and CN218974689U have complex structures, and the coupling distance between the light source and the optical fiber is too close. For example, if quartz optical fiber is used, although quartz optical fiber can withstand high temperatures, the core of quartz optical fiber is relatively small and the luminous flux is not large. Utility Model Content

[0003] In order to solve the above problems, the utility model aims to propose a light-guiding lighting device, which adopts plastic optical fiber and cooperates with a heat sink for heat dissipation. The luminous flux of plastic optical fiber is larger than that of quartz optical fiber. After the device is powered on, the lamp beads are lit, and the heat generated by the lamp beads is dissipated through the heat sink to ensure that the operating temperature of the lamp beads and the plastic optical fiber does not exceed the temperature. The light emitted by the lamp beads is guided by a coupler in combination with the plastic optical fiber. The structure is simple and the light-guiding efficiency is high.

[0004] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0005] A light-guiding lighting device comprises a lamp bead, a heat sink, a plastic optical fiber and a coupler. The lamp bead is mounted on the heat sink, the coupler is mounted on the heat sink to cover the lamp bead, and the coupler is equipped with a plastic optical fiber to guide the light emitted by the lamp bead.

[0006] Furthermore, a plurality of heat dissipation holes are provided at the bottom of the coupler near the lamp beads.

[0007] Furthermore, a stopper for limiting the position of the plastic optical fiber is provided inside the coupler, and a set safety distance is maintained between the stopper and the lamp bead.

[0008] Furthermore, the lamp beads and the coupler are both mounted on the radiator via fixing bolts.

[0009] Furthermore, it also includes a lamp bead mounting base plate, and the lamp bead is mounted on the radiator through the lamp bead mounting base plate and the fixing bolts.

[0010] Beneficial effects: The utility model adopts plastic optical fiber and cooperates with a radiator for heat dissipation. Compared with quartz optical fiber, the luminous flux of plastic optical fiber is larger. After the device is powered on, the lamp beads are lit, and the heat generated by the lamp beads is dissipated through the radiator to ensure that the working temperature of the lamp beads and the plastic optical fiber does not exceed the temperature. The light emitted by the lamp beads is guided by the coupler in combination with the plastic optical fiber. The structure is simple and the light guidance efficiency is high.

The illustrative embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation on the present invention. In the accompanying drawings:

[0012] Figure 1 It is a structural schematic diagram of the light-guiding lighting device described in an embodiment of the utility model. DETAILED DESCRIPTION

[0013] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0015] Example 1

[0016] See also Figure 1 A light-guiding lighting device comprises a lamp bead 1, a heat sink 2, a plastic optical fiber 3 and a coupler 4, wherein the lamp bead 1 is mounted on the heat sink 2, the coupler 4 is mounted on the heat sink 2 and is used to cover the lamp bead 1, and the plastic optical fiber 3 is installed in the coupler 4 and is used to guide the light emitted by the lamp bead.

[0017] This embodiment uses plastic optical fiber and cooperates with a heat sink for heat dissipation. The luminous flux of plastic optical fiber is larger than that of quartz optical fiber. After the device is powered on, the lamp beads are lit, and the heat generated by the lamp beads is dissipated through the heat sink to ensure that the operating temperature of the lamp beads and the plastic optical fiber does not exceed the temperature. The light emitted by the lamp beads is guided by the coupler and the plastic optical fiber, with a simple structure and high light guiding efficiency.

[0018] In a specific example, a plurality of heat dissipation holes 401 are provided at the bottom of the coupler 4 near the lamp bead 1 .

[0019] The high-power LED lamp beads used for ambient lighting in this embodiment will generate a large amount of heat when working. The heat dissipation holes of the coupler near the lamp beads can further accelerate the dissipation of hot air to prevent adverse effects on the operation of the plastic optical fiber and the lamp beads.

[0020] In a specific example, a stopper 402 for limiting the position of the plastic optical fiber 3 is disposed inside the coupler 4 , and a set safety distance is maintained between the stopper 402 and the lamp bead 1 .

[0021] When the plastic optical fiber is inserted into the coupler and reaches the limit stop of the coupler, it cannot enter any further, thereby ensuring that the plastic optical fiber maintains a fixed distance from the lamp bead, and the ambient temperature of this safe distance is lower than the specified operating temperature of the plastic optical fiber, thereby ensuring the long-term safe and stable use of the plastic optical fiber.

[0022] In a specific example, the lamp bead 1 and the coupler 4 are both mounted on the heat sink 2 via fixing bolts 5 .

[0023] In a specific example, a lamp bead mounting base plate 6 is further included, and the lamp bead 1 is mounted on the radiator through the lamp bead mounting base plate 6 and the fixing bolts 5 .

[0024] In this embodiment, the lamp beads are fixedly installed by fixing bolts in conjunction with the lamp bead installation floor, which is easy to install and disassemble, and the installation structure is firm.

[0025] The working principle of this embodiment is as follows: after the device is powered on, the lamp beads will light up, and the heat generated by the lamp beads will be dissipated through the lamp bead mounting base to the radiator, thereby ensuring that the working temperature of the lamp beads and the plastic optical fiber does not exceed the temperature. The coupler is fixed to the radiator through fixing bolts, and the plastic optical fiber is inserted into the coupler. When the optical fiber reaches the limit stop of the coupler, it cannot enter any further, thereby ensuring that the plastic optical fiber maintains a fixed distance from the lamp beads, and the ambient temperature at this distance is lower than the specified operating temperature of the plastic optical fiber, thereby ensuring the long-term safe and stable use of the plastic optical fiber. The heat dissipation holes on the coupler further accelerate the dissipation of heat generated by the lamp beads, and the light generated by the lamp beads is introduced into flammable, explosive, toxic and harmful places through the plastic optical fiber.

[0026] To sum up, the light-guiding lighting device of this embodiment has a simple and reliable structure. The high-power LED lamp beads used for ambient lighting will generate a large amount of heat when working. The heat dissipation holes of the coupler near the lamp beads cooperate with the radiator to facilitate the dissipation of heat. The optical fiber and the lamp beads are kept at a fixed distance through the limit block of the coupler and will not be affected by the high temperature generated when the lamp beads are working. The service life of plastic optical fiber used in ambient lighting is greatly improved. The use of plastic optical fiber as a lighting illuminant in flammable, explosive, toxic and harmful places will not generate electric sparks and is not easy to corrode, which can greatly improve the safety of use and service life.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
