Abstract
Description
Technical Field
[0001] This utility model relates to the field of explosion-proof lighting technology, specifically to an energy-saving explosion-proof lighting fixture. Background Technology
[0002] Explosion-proof lighting fixtures are lighting devices specifically designed for flammable and explosive environments (such as petroleum, chemical, mining, and pharmaceutical industries). Their core function is to prevent potential arcs, sparks, or high temperatures generated inside the fixture from igniting surrounding flammable materials through structural design, material selection, and temperature control. A search revealed existing technology (application number: CN201821721658.1) for highly efficient and energy-saving explosion-proof lighting fixtures. The document describes the light source as a single-plug, starterless fluorescent lamp, a type of cold cathode gas discharge lamp. Its light-emitting principle utilizes the discharge between electrodes to generate ultraviolet radiation from mercury atoms, thereby exciting the lamp tube. The fluorescent material on the inner wall emits light. This type of fluorescent lamp has high luminous efficiency (about 3 times that of incandescent lamps), long service life, and does not require a starter to start (usually there is a conductive layer on the lamp tube wall called the ignition layer, which is used to ignite the fluorescent lamp; when the lamp tube breaks, the ignition layer is also destroyed, and the lamp goes out). The cathode temperature is low (around 200℃), making it a safe and practical light source that is more suitable for actual lighting environments. It is highly efficient and energy-saving, saving more than 30% energy compared to incandescent lamps. However, the fluorescent lamps used in explosion-proof lighting fixtures in the current technology are sensitive to temperature, and prolonged use can cause the lamp to heat up, affecting the brightness and service life. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, an energy-saving explosion-proof lighting fixture is provided to solve the problem that fluorescent lamps used in existing explosion-proof lighting fixtures are sensitive to temperature, and that prolonged use of the fixture can cause the lighting brightness and lifespan to be affected by the heat generated.
[0004] To achieve the above objectives, an energy-saving explosion-proof lighting fixture is provided, comprising: an explosion-proof lighting fixture body, wherein a light source control cavity and an LED light source cavity are provided at the upper and lower ends of the explosion-proof lighting fixture body.
[0005] Cooling rings are distributed around the outer shell of the LED light source cavity. Heat dissipation fins are fixed at equal intervals on the upper surface of the cooling rings. A liquid guide port is opened on the upper end face of the cooling rings. A liquid storage cavity is provided on the inner side of the cooling rings. The side end of the cooling rings is welded to the explosion-proof lamp body shell through a heat transfer plate. A human infrared sensor, a remote control receiver, and a light sensor are embedded in the lower shell of the explosion-proof lamp body.
[0006] Furthermore, the explosion-proof lamp body has symmetrically welded fixing plates on the left and right sides of the upper shell surface, and the lamp bracket is installed on the side end of the fixing plate by bolts.
[0007] Furthermore, an LED energy-saving lamp is installed inside the LED light source cavity, and a power connector is provided on the right end face of the light source control cavity.
[0008] Furthermore, a liquid-blocking cap is attached to the surface of the liquid guide port; and the lower end of the liquid guide port is connected to the liquid storage cavity.
[0009] Furthermore, the outer side of the human infrared sensor is covered by a protective cover, which is screwed onto the surface of the lower housing of the explosion-proof lamp body.
[0010] Furthermore, the cooling ring block has a hollow rectangular cross-section; and a notch is provided at the right end of the cooling ring block, through which coolant is stored in the cooling ring block via a liquid storage cavity.
[0011] Furthermore, the remote control receiver and the light sensor are located at the rear end of the LED light source cavity, while the human infrared sensor is located at the front end of the LED light source cavity.
[0012] The beneficial effects of this utility model are as follows: the energy-saving explosion-proof lamp utilizes a cooling ring block containing coolant, which is distributed around the outside of the light source control cavity housing of the explosion-proof lamp. The coolant in the cooling ring block absorbs the heat conducted by the heat transfer plate to the light source area and control area of the explosion-proof lamp, and then the heat dissipation fins dissipate the heat absorbed by the coolant into the outside air. This facilitates faster heat dissipation of the explosion-proof lamp, reduces the temperature rise of the explosion-proof lamp during long-term lighting, and avoids increased energy consumption caused by high-temperature lighting. The lamp is activated by human infrared sensor and light sensor to control the lighting brightness, saving electricity and improving the energy-saving efficiency of the explosion-proof lamp.

[0018] Reference Figures 1 to 4 As shown, this utility model provides an energy-saving explosion-proof lighting fixture, including: an explosion-proof lighting fixture body 1, with a light source control cavity 11 and an LED light source cavity 13 provided at the upper and lower ends of the explosion-proof lighting fixture body 1.
[0019] Cooling ring blocks 2 are distributed around the outer shell of the LED light source cavity 13. Heat dissipation fins 21 are fixed at equal intervals on the upper surface of the cooling ring blocks 2. A liquid guide port 22 is opened on the upper end face of the cooling ring blocks 2. A liquid storage cavity 23 is provided on the inner side of the cooling ring blocks 2. The side end of the cooling ring blocks 2 is welded to the shell of the explosion-proof lamp body 1 through a heat transfer plate 25. A human infrared sensor 3, a remote control receiver 4 and a light sensor 5 are embedded in the lower shell of the explosion-proof lamp body 1.
[0020] Coolant is poured into the cooling ring 2 at the upper end of the explosion-proof lamp body 1. The explosion-proof lamp body 1 is then installed and fixed by the lamp bracket 12. The coolant in the cooling ring 2 absorbs the heat conducted by the heat transfer plate 25 to the light source area and control area of the explosion-proof lamp. The heat dissipation fins 21 then dissipate the heat absorbed by the coolant into the outside air, which facilitates the heat dissipation of the explosion-proof lamp, reduces the temperature rise of the explosion-proof lamp during long-term illumination, and avoids increased energy consumption caused by high-temperature illumination. When the human infrared sensor 3 detects that a person is approaching, it controls the explosion-proof lamp body 1 to turn on the light. When the person leaves, the light turns off. The light sensor 5 senses the ambient light conditions and controls the illumination brightness of the LED energy-saving lamp in the explosion-proof lamp body 1, which helps to save electricity and improve the energy-saving efficiency of the explosion-proof lamp.
[0021] In this embodiment, fixing plates 15 are symmetrically welded to the left and right sides of the upper shell of the explosion-proof lamp body 1, and lamp brackets 12 are installed on the side ends of the fixing plates 15 by bolts.

The LED energy-saving lamp is energy-efficient, reducing energy consumption for lighting the explosion-proof lamp body 1. The power connector 14 provides an external power source to supply power to the explosion-proof lamp body 1 for lighting operations.
[0023] In this embodiment, a liquid-blocking cap 24 is attached to the surface of the liquid guide port 22; and the lower end of the liquid guide port 22 is connected to the liquid storage cavity 23. The cooling ring block 2 has a hollow rectangular cross-section; and a notch is provided at the right end of the cooling ring block 2, through which the cooling ring block 2 stores coolant.
[0024] As a preferred implementation, the coolant in the liquid storage channel 23 introduced into the cooling ring block 2 can easily absorb the heat conducted by the heat transfer plate 25, accelerate the heat dissipation of the explosion-proof lamp, reduce the temperature rise of the explosion-proof lamp during long-term lighting, and avoid high temperature affecting the service life of the explosion-proof lamp body 1.
[0025] In this embodiment, a protective cover 31 is attached to the outside of the human infrared sensor 3, and the protective cover 31 is screwed onto the surface of the lower housing of the explosion-proof lamp body 1. The remote control receiver 4 and the light sensor 5 are located at the rear end of the LED light source cavity 13, and the human infrared sensor 3 is located at the front end of the LED light source cavity 13.
[0026] As a preferred implementation, the protective cover 31 protects the human infrared sensor 3, isolating it from the external environment. The remote control receiver 4 receives external remote control signals to control the on / off state and brightness of the explosion-proof lamp body 1. The light sensor 5 detects whether personnel are passing through a certain range; when no personnel are within the illumination area of the explosion-proof lamp body 1, the lamp body 1 turns off, saving electricity and reducing energy consumption.
[0027] This utility model of energy-saving explosion-proof lighting fixtures effectively solves the problem that fluorescent lamps used in existing explosion-proof lighting fixtures are sensitive to temperature, and that prolonged use can cause the lighting brightness and lifespan to be affected by the heat rise of the lamps. It facilitates faster heat dissipation of explosion-proof lighting fixtures, reduces the temperature rise of explosion-proof lighting fixtures during prolonged lighting, avoids increased energy consumption caused by high-temperature lighting, saves electricity consumption of explosion-proof lighting fixtures, and improves the energy-saving efficiency of explosion-proof lighting fixtures. It is suitable for energy-saving explosion-proof lighting fixtures.
