Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to an energy-saving and explosion-proof lighting fixture. Background Technology

[0002] In industrial production environments, such as chemical, petroleum, and mining industries, lighting fixtures are often surrounded by flammable and explosive gases, dust, and other substances. Traditional lighting fixtures, during prolonged use, are prone to generating electrical sparks or high temperatures due to internal electrical component heating and aging wiring. If these high temperatures or sparks come into contact with surrounding flammable and explosive materials, they can trigger violent explosions, causing equipment damage, production stoppages, and seriously threatening the lives of workers. Traditional explosion-proof lighting fixtures have relatively simple protective mechanisms, typically only providing a certain degree of protection after an explosion has occurred. They lack the ability to proactively prevent and buffer the impact of explosions, making it difficult to fundamentally guarantee the safe use of lighting fixtures in complex and hazardous environments. Summary of the Invention

[0005] As a preferred embodiment of the present invention, a pulley is rotatably installed inside the protective plate, and an auxiliary rope slides through the pulley. A piston plate for blocking the main airbag is provided at the bottom end of the protective plate near the main airbag.

[0006] As a preferred embodiment of the present invention, the internal cavity of the protective plate is connected to the surface of the energy-saving lamp head and a filter for filtering air is installed, and the filter is provided with a pressure relief and exhaust valve.

[0007] As a preferred embodiment of the present invention, the surface of the protective plate is provided with a cooling mechanism, the cooling mechanism includes a sealing slide plate that slides through the protective plate, a fixing plate is fixedly installed on the inner wall of the protective plate, a spring is fixedly installed between the fixing plate and the sealing slide plate, and a heat conduction pipe is installed in communication between the heat storage pipe and the interior of the sealing slide plate.

[0008] As a preferred embodiment of the present invention, an outer tube is fixedly installed at the top of the protective plate, and the outer tube and the sealing plate are connected by a connecting pipe. A cooling water pipe for cooling the heat flow is fixedly installed inside the outer tube, and a breathable membrane is fixedly installed on the inner wall of the cooling water pipe.

[0009] As a preferred embodiment of the present invention, the outer surface of the cooling water pipe is connected to and installed with a plurality of adsorption rings, and two baffles are fixedly installed inside the adsorption rings, and the space between the two baffles is filled with adsorbed carbon fragments for filtering hot gas flow.

[0010] As a preferred embodiment of the present invention, the outer surface of the adsorption ring is provided with a through hole, and the gap between the outer tube and the cooling water pipe is filled with a sponge layer, and the sponge layer is connected to the through hole.

[0011] As a preferred embodiment of the present invention, a sealing mechanism is provided between the energy-saving lamp holder and the protective plate. The sealing mechanism includes a support ring fixedly installed at one end of the heat storage tube, a rubber block for elastic support fixedly installed on the surface of the support ring near the energy-saving lamp holder, a detachable sealing ring fixedly installed on the outer surface of the energy-saving lamp holder, and the free end of the rubber block connected to the detachable sealing ring.

[0012] As a preferred embodiment of the present invention, the rubber stack is constructed with a wavy structure, the interior of the rubber stack is filled with a honeycomb aluminum foil layer, and a pressure sensor is provided between the honeycomb aluminum foil layer and the inner wall of the rubber stack.

[0013] As a preferred embodiment of the present invention, the outer surface of the energy-saving lamp holder is covered with a heat sink plate, and the outer surface of the heat sink plate is provided with a plurality of heat dissipation holes.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. When the internal and surrounding temperatures of the lamp rise continuously due to prolonged use, the heat-absorbing pad can effectively absorb the heat flow inside the protective plate and guide it into the heat storage pipe. The heat balance plate can balance the heat flow around the bulb and inside the main airbag, stabilizing the temperature. When the heat flow accumulates to a certain level, the main airbag expands and the internal elastic auxiliary airbag is compressed. Finally, multiple main airbags push out the piston plate and burst out instantly, quickly covering the bulb. This active protection mechanism can provide comprehensive protection for the bulb in time before or in the early stage of danger, greatly reducing the risk of explosion caused by high temperature, effectively ensuring the safety of lamp use in complex and dangerous environments, and reducing equipment damage caused by accidents.

[0015] 2. When the heat flow inside the protective plate is too large, the present invention first conducts the heat to the sealing slide plate through the heat pipe, causing it to be pushed out, thus realizing the initial heat exchange between the inside of the protective plate and the outside. At the same time, the water source in the cooling water pipe cools and dries the heat flow, and the generated cold air further accelerates the heat dissipation process. This multi-layer heat dissipation design can quickly and effectively reduce the temperature inside the lamp, avoid the lamp performance degradation due to high temperature, and ensure that the lamp maintains stable luminous efficiency and working performance during long-term use.

[0016] 3. In the initial stage of temperature rise, the present invention prioritizes heat dissipation through a heat dissipation mechanism. Through the coordinated action of components such as heat pipes, sealing plates, and cooling water pipes, heat is dissipated as much as possible to maintain the normal operating temperature of the lamp. At the same time, when heat dissipation is insufficient to control the temperature rise and heat flow accumulates to a dangerous level, the main airbag will be deployed for overall protection. This intelligent collaborative mechanism not only ensures the efficient operation of the lamp within the normal operating temperature range, but also enables timely activation of protective measures in emergency situations, thereby improving the reliability and safety of the lamp.

[0017] 4. This invention uses rubber stacks for sealing, and the rubber stacks adopt a corrugated structure and are filled with a honeycomb aluminum foil layer, which can provide good elastic support and sealing effect, effectively preventing external dust, moisture and other impurities from entering the lamp, protecting the internal electrical components from damage, and extending the lamp's service life. At the same time, the pressure sensor set between the honeycomb aluminum foil layer and the inner wall of the rubber stack can monitor the sealing status in real time, ensuring that the sealing performance is always at a good level.

[0018] The lamp of this invention reduces energy waste caused by high temperature through its efficient heat dissipation design, improves energy utilization efficiency, and conforms to the development trend of energy conservation and emission reduction. In addition, the design of disassembling sealing rings and other components facilitates lamp maintenance and component replacement, reduces waste generation, further reflects the concept of environmental protection, and is conducive to sustainable development.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-9This invention provides an energy-saving and explosion-proof lighting fixture, including a connecting part 1 and an energy-saving lamp holder 3. The energy-saving lamp holder 3 is installed at the bottom of the connecting part 1. A protective plate 2 is installed on the outer surface of the connecting part 1. A protective mechanism 4 is provided inside the protective plate 2. The protective mechanism 4 includes a main airbag 45 installed inside the protective plate 2. A branch pipe 46 for heat charging is connected to the surface of the main airbag 45. An auxiliary rope 41 is connected to one end of the main airbag 45. An installation plate 43 is installed inside the protective plate 2 near the main airbag 45. An elastic clip 44 is fixedly installed on the surface of the auxiliary rope 41 and is snapped onto the surface of the installation plate 43. An elastic auxiliary airbag 47 connected to the auxiliary rope 41 is installed inside the main airbag 45. A heat storage pipe 48 is fixedly installed on the inner wall of the protective plate 2 near the main airbag 45. A heat balance plate 49 is installed between the heat storage pipe 48 and the inner cavity of the protective plate 2. Multiple sets of heat-absorbing pads 410 are installed on the surface of the heat storage pipe 48 near the energy-saving lamp holder 3.

[0023] When the lamp is in use, the protective plate 2 protects the lamp. During prolonged use, the temperature around and inside the lamp will continuously rise. The heat-absorbing pad 410 absorbs the heat flow inside the protective plate 2 and guides it into the heat storage pipe 48. At this time, the heat balance plate 49 balances and stabilizes the heat flow around the bulb and inside the main airbag 45, making the internal temperature distribution of the lamp more uniform and avoiding local overheating. When the heat flow increases, the main airbag 45 will expand, and the elastic auxiliary airbag 47 inside the main airbag 45 will compress. When it accumulates to a certain level, the multiple main airbags 45 inside the protective plate 2 will push out the piston plate 411 and burst instantly, thereby covering and protecting the bulb, increasing the overall explosion-proof effect of the lamp, reducing the risk of explosion, and ensuring safe use.

[0024] In some embodiments, a pulley 42 is rotatably mounted inside the protective plate 2, and an auxiliary rope 41 slides through the pulley 42. A piston plate 411 for blocking the main airbag 45 is provided at the bottom end of the protective plate 2 near the main airbag 45.

[0025] When the main airbag 45 inflates to a certain extent, the auxiliary rope 41 is stressed, the elastic block 44 disengages from the mounting plate 43, and the auxiliary main airbag 45 completes the bursting action. The piston plate 411 is pushed out, ensuring that the main airbag 45 bursts in a timely and accurate manner. At the same time, the locking structure between the elastic block 44 and the mounting plate 43 stably fixes the auxiliary rope 41 under normal conditions, ensuring the stability of the protective mechanism 4, and can smoothly disengage when bursting is required.

[0026] In some embodiments, the internal cavity of the protective plate 2 is connected to the surface of the energy-saving lamp holder 3 and a filter 412 for filtering air is installed, and the filter 412 is provided with a pressure relief and exhaust valve.

[0027] The filter 412 connects the internal cavity of the protective plate 2 to the outside, filters the air entering the protective plate 2, prevents dust and other impurities from entering, and reduces the damage of dust and other impurities to the internal electrical components of the lamp. When the internal pressure of the protective plate 2 is too high, the air valve opens to release pressure and exhaust air, maintains the internal pressure of the protective plate 2, and ensures the normal operation of the lamp.

[0028] In some embodiments, a cooling mechanism 5 is provided on the surface of the protective plate 2. The cooling mechanism 5 includes a sealing slide plate 54 that slides through the protective plate 2. A fixing plate 51 is fixedly installed on the inner wall of the protective plate 2. A spring 53 is fixedly installed between the fixing plate 51 and the sealing slide plate 54. A heat conduction pipe 52 is installed in communication between the heat storage pipe 48 and the interior of the sealing slide plate 54.

[0029] The heat flow inside the heat storage pipe 48 is conducted to the sealing slide plate 54 through the heat conduction pipe 52. When the heat flow accumulates to a certain level, the heat causes the sealing slide plate 54 to overcome the elastic force of the spring 53 and slide outward, realizing the heat exchange between the inside of the protective plate 2 and the outside world, and dissipating heat. The elastic force of the spring 53 enables the sealing slide plate 54 to automatically reset when the temperature drops, realizing the automatic adjustment of the heat dissipation process and maintaining the stable internal temperature of the lamp.

[0030] In some embodiments, an outer tube 56 is fixedly installed on the top of the protective plate 2, and the outer tube 56 and the sealing plate 54 are connected by a connecting pipe 55. A cooling water pipe 58 for cooling the heat flow is fixedly installed inside the outer tube 56, and a breathable membrane 59 is fixedly installed on the inner wall of the cooling water pipe 58.

[0031] Among them, the sliding of the sealing plate 54 drives the air flow in the outer pipe 56 through the connecting pipe 55. The combined design of the cooling water pipe 58 and the breathable membrane 59 utilizes the principle of heat absorption by water evaporation to quickly reduce the temperature of the heat flow and improve the heat dissipation efficiency. The sealing plate 54 and the heat conduction pipe 52 work together to form a multi-level heat dissipation system to better cope with different degrees of temperature rise.

[0032] In some embodiments, a plurality of adsorption rings 57 are connected to the outer surface of the cooling water pipe 58, and two baffles 510 are fixedly installed inside the adsorption rings 57, with adsorbent carbon fragments 511 for filtering hot gas filling between the two baffles 510.

[0033] When the hot gas passes through the adsorption ring 57, the adsorbed carbon fragments 511 adsorb and filter impurities and harmful substances in the gas, reducing environmental pollution. The design of the baffle 510 makes the adsorption of carbon fragments 511 inside the adsorption ring 57 more stable, improving the adsorption and filtration effect.

[0034] In some embodiments, the outer surface of the adsorption ring 57 is provided with a through hole, and the gap between the outer tube 56 and the cooling water pipe 58 is filled with a sponge layer 512, and the sponge layer 512 communicates with the through hole.

[0035] The adsorption ring 57 has through holes on its outer surface that are connected to the sponge layer 512. The sponge layer 512 absorbs moisture around the cooling water pipe 58. When hot gas passes through the through holes, the moisture evaporates and further cools the gas. At the same time, the gas filtered by the adsorption ring 57 is adsorbed again to ensure that the gas is purer and improve the overall heat dissipation and protection performance.

[0036] In some embodiments, a sealing mechanism 6 is provided between the energy-saving lamp holder 3 and the protective plate 2. The sealing mechanism 6 includes a support ring 61 fixedly installed at one end of the heat storage tube 48. A rubber stack 62 for elastic support is fixedly installed on the surface of the support ring 61 near the surface of the energy-saving lamp holder 3. A detachable sealing ring 63 is fixedly installed on the outer surface of the energy-saving lamp holder 3, and the free end of the rubber stack 62 is connected to the detachable sealing ring 63.

[0037] Among them, the support ring 61 fixes the rubber stack 62, the rubber stack 62 provides elastic support and sealing, and its free end is connected to the detachable sealing ring 63 on the energy-saving lamp holder 3 to prevent external dust, moisture and other substances from entering the lamp and protect the internal electrical components; the elasticity of the rubber stack 62 can buffer external impact force, reduce damage to the energy-saving lamp holder 3 and improve the impact resistance of the lamp.

[0038] In some embodiments, the rubber stack 62 is constructed with a wavy structure, the interior of the rubber stack 62 is filled with a honeycomb aluminum foil layer, and a pressure sensor is disposed between the honeycomb aluminum foil layer and the inner wall of the rubber stack 62.

[0039] Among them, the wavy rubber stack 62 increases the elastic deformation capacity, the honeycomb aluminum foil layer enhances the structural strength and heat insulation performance, and improves the sealing and buffering effect; the pressure sensor monitors the internal pressure change of the rubber stack 62 in real time, which facilitates timely detection of abnormalities and maintenance.

[0040] In some embodiments, the outer surface of the energy-saving lamp holder 3 is covered with a heat sink 7, and the outer surface of the heat sink 7 is provided with a plurality of heat dissipation holes.

[0041] Among them, the heat sink 7 covers the energy-saving lamp holder 3, and the heat dissipation holes increase the heat dissipation area, accelerate the air flow around the energy-saving lamp holder 3, and ensure the normal light emission and working performance of the lamp.

[0042] Working principle: When the lamp is in use, the protective plate 2 protects the lamp. During prolonged use, the temperature around and inside the lamp will continuously rise. When the heat flow accumulates to a certain level, the heat causes the sealing slide plate 54 to overcome the elastic force of the spring 53 and slide outward, realizing heat exchange between the inside of the protective plate 2 and the outside world for heat dissipation. At the same time, when the heat storage tube 48 increases, the heat balance plate 49 can balance and stabilize the heat flow around the bulb and the heat flow inside the main air bag 45, making the internal temperature distribution of the lamp more uniform and avoiding local overheating. When the heat flow increases, the main air bag 45 will expand, and the elastic auxiliary air bag 47 inside the main air bag 45 will compress. When it accumulates to a certain level, the multiple main air bags 45 inside the protective plate 2 will push out the piston plate 411 and burst open instantly, thereby covering and protecting the bulb, increasing the overall explosion-proof effect of the lamp, reducing the risk of explosion, and ensuring safe use.

[0043] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
