Description

Technical Field

[0001] The present invention belongs to the field of lighting equipment, and in particular relates to a multifunctional security lighting equipment. Background Art

[0002] Security lighting equipment, featuring intelligent control, high-efficiency lighting sources, and scenario-based design, is widely used in public and security sectors, transportation and infrastructure, industrial and commercial settings, home and community security, and other emergency and special scenarios. With the advancement of technology, lighting control systems have also developed significantly, and the application of smart lighting equipment is becoming increasingly widespread. Smart lighting devices leverage IoT technology to enable remote dimming, timing control, scene mode switching, and integrate with security cameras, sensors, and other devices. They can also automatically optimize lighting strategies to reduce energy waste and support remote operation via mobile apps, allowing real-time monitoring of lighting status.

[0003] Currently, most security lighting equipment has relatively simple functions. In emergency situations, such as smoke and fog, they are often surrounded by a large amount of smoke. Although sprinklers linked to smoke detectors can provide some fire extinguishing and defogging, they still significantly affect the lighting effect and may even delay emergency rescue. Existing patent CN217208690U discloses an adjustable structure for safe city video surveillance equipment. Two fans are activated to rapidly circulate air within the bellows, facilitating heat dissipation. Activated alumina plates then absorb moisture from the airflow, preventing subsequent airflow from reaching the lens surface and causing fogging. This device has automatic defogging and smoke removal functions, but is limited to surveillance equipment. Another example is existing patent CN201620351997.X, which discloses a wind-solar hybrid streetlight capable of removing fog and haze. This device achieves this through solar panels and a wind turbine generator. A convex lens focuses light, purifying the surrounding air and redirecting the travel direction of a struck vehicle. This lighting equipment has purification and demisting functions, but it is mainly used in outdoor lighting applications. Its installation conditions are subject to certain restrictions, and it is not suitable for the actual needs of improving security emergency response efficiency in many application scenarios.

DETAILED DESCRIPTION

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other unless they conflict. For the convenience of description, the words "upper", "lower", "left", and "right" appearing below only indicate the upper, lower, left, and right directions consistent with the drawings themselves and do not limit the structure.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Examples, such as Figures 1-10As shown, the present invention provides a multifunctional security lighting device, including a housing 1, wherein the top of the housing 1 is provided with a threaded interface section 1222, the bottom of the housing 1 is provided with a lampshade 2, the interior of the lampshade 2 is provided with a lamp board 3, and the lamp board 3 is provided with a plurality of LED lamp beads 4 and a lighting power cord 5 for connecting the LED lamp beads 4 to a power source. In order to improve the lighting effect of the device under normal conditions and emergency conditions, the housing 1 provided by the present invention is arched with its back facing upward, both ends of the housing 1 are round and are used to install the lampshade 2 and the lamp board 3, a pair of vertical mounting tubes 6 are provided on the housing 1 near the lampshades 2 at both ends, colored lamps 7 are provided in the mounting tubes 6, and the colors of the colored lamps 7 in the four mounting tubes 6 are different from each other, a shaft cylinder 8 perpendicular to its vertical plane is provided at the middle bottom of the housing 1, a fan 9 is provided in the shaft cylinder 8, an air outlet cover 10 and an air inlet cover 11 are provided at both ends of the shaft cylinder 8, and a lamp is provided at the middle top of the housing 1. The base 12 includes a rotating base body 121 and a mounting base body 122 connected in an upper and lower transmission manner. The two sides of the rotating base body 121 partially overlap with the two sides of the outer shell 1 and are provided with a waist-shaped sinking groove 123 at the overlapping position. A pair of servo steering engines 13 are provided inside the rotating base body 121. The power output end of the servo steering engine 13 faces upward and is provided with a transmission mechanism 14. The transmission mechanism 14 is used to drive the rotating base body 121 and the mounting base body 122 to perform relative rotational motion. The fixed end of the servo steering engine 13 is provided with a fixing screw 15, and the fixing screw 15 is provided in a countersunk hole 124 opened in the waist-shaped sinking groove 123.

[0033] Specifically, the lighting power cable 5, the color lamp power cable 73, and the fan power cable 16 all extend from the interior of the housing 1 to the top of the mounting base 122 and connect to power connections in the installation environment. The lampshade 2, the lamp panel 3, and the plurality of LED lamp beads 4 form a lighting unit. The housing 1 provides a mounting base for both lighting units. Within the structural limitations of the housing 1, the two lighting units maintain a certain lighting spacing, and their illumination ranges partially overlap. A one-for-one backup mode can be used when not necessary, and operating both lighting units simultaneously effectively expands the illumination range.

[0034] The entire structure of this device includes a housing 1, which utilizes a lamp holder 12 as its mounting base in the application scenario. The lamp holder 12 includes a mounting base 122 and a rotating base 121. The housing 1 and rotating base 121 are driven by a servo motor 13 and a transmission mechanism 14 to achieve servo rotation, with a rotation angle between 60 and 120 degrees. Because each power cord has a certain length margin after connection, the rotation of this lighting device does not significantly affect the connection performance of each power cord. Furthermore, the two pairs of mounting tubes 6 integrally formed on the housing 1 contain a total of four colored lights 7. The colored lights 7 on the mounting tubes 6 rotate synchronously when the housing 1 rotates. Especially in emergency situations, the light of the colored lights 7 can penetrate smoke and provide corresponding warning and indication functions. Furthermore, by installing a fan 9 in the bottom shaft 8 of the housing 1, it can not only achieve heat dissipation, but also timely remove fog and smoke in the event of fog and smoke around the device, dispersing smoke that gathers around the device or reducing the density of smoke near the light source, which is conducive to providing better lighting effects in emergency conditions and improving the security performance of the device. The device is reasonably designed and has high applicability for installation indoors, outdoors and in other scenarios. It has emergency rotation function, demisting function and warning function, so it has a high comprehensive utilization rate.

[0035] In order to improve the warning performance of the color lamp 7, as Figure 7 As shown, the color lamp 7 provided by the present invention includes a xenon lamp body 71. A conductive sleeve 72 is threadedly connected to the bottom of the xenon lamp body 71. A color lamp power cord 73 is installed at the bottom of the conductive sleeve 72. The color lamp power cord 73 is located inside the housing 1 and extends from the top of the mounting base 122. A spherical color cover 74 is installed on the top of the xenon lamp body 71. The conductive sleeve 72 is connected to the power supply wiring in the application scenario of the device via the color lamp power cord 73. By installing the xenon lamp body 71 and the color cover 74 in the mounting tube 6, the power supply is connected, meeting the power requirements for light emission and ensuring the overall stability of the color lamp 7. Furthermore, the xenon lamp body 71 has high luminous efficiency and strong penetration, meeting the needs of industrial lighting and security requirements in other scenarios. In particular, the color cover 74 of the natural color lamp 7 can make the light emitted by the xenon lamp body 71 colored, effectively enhancing its warning lighting function in emergency scenarios and improving the security performance of the device.

[0036] Considering the structural performance of this lighting equipment, such as Figures 1-4As shown, the outer diameter of the color shield 74 provided by the present invention is the same as the outer diameter of the mounting tube 6, and the edge of the color shield 74 is located at the level where the top surface of the mounting tube 6 connects to the outer shell 1. This provides the color lamp 7 with a high degree of pressure and impact resistance through the spherical color shield 74, while also establishing a good transition relationship with the outer shell 1. While ensuring a good integration between the color lamp 7 and the outer shell 1, it can also reduce the sealing effect of the color lamp 7 to a certain extent, preventing a large amount of dust from accumulating on the mounting surface of the color lamp 7.

[0037] To improve the utilization of the fan 9, the surface of the shaft cylinder 8, which serves as its mounting base, is integrally connected to the shell surface of the housing 1. The lowest level of the shaft cylinder 8 is lower than the lowest surface of the lampshade 2. Annular grooves are provided at both ends of the shaft cylinder 8, which can nest with the edges of the air inlet hood 11 and the air outlet hood 10. Furthermore, flange holes for mounting the air inlet hood 11 and the air outlet hood 10 are provided on the annular grooves. There are at least six flange holes on the same plane to improve the stability of the screw mounting of the air inlet hood 11 and the air outlet hood 10 at both ends of the shaft cylinder 8. This ensures that the axial blowing range of the fan 9 overlaps with the lighting unit near the light source to a certain extent, enabling heat exchange with the air near the lighting source and facilitating heat dissipation. Furthermore, in emergency situations, the emergency activation of the fan 9 can effectively disperse smoke that has accumulated around the device or reduce the density of smoke near the light source, thereby providing better lighting for emergency survival and rescue personnel.

[0038] like Figure 2 As shown, considering that the motor of the fan 9 is generally fixed on the air inlet cover 11, a fan power cord 16 connected to the fan 9 is provided on the rear side of the air inlet cover 11, and a clamping member 17 for clamping the fan power cord 16 is provided on the housing 1. The side of the housing 1 is provided with a through-hole connected to the interior thereof. The fan power cord 16 passes through the clamping member 17 and the through-hole and then passes out from the top of the mounting base body 122. In this way, by comprehensively arranging the fan power cord 16, the fan 9 can establish an effective electrical connection with the power wiring / socket in the application scenario of this device. The clamping of the clamping member 17 can prevent the fan power cord 16 from swinging freely and causing poor contact of the fan 9.

[0039] Furthermore, if Figure 10 As shown, the cross-section of the clamping member 17 is E-shaped, and a mushroom head 171 is provided at its middle end. The E-shaped structure of the clamping member 17 forms two wiring openings, the openings of which face the surface of the housing 1. The mushroom head 171 can reduce the diameter of the wiring openings to a certain extent, thereby providing a certain elastic clamping effect for the fan power cable 16 when it is passed through the wiring openings.

[0040] like Figure 9 As shown, the rotating seat body 121 provided by the present invention includes a transition section 1211 connected to the outer shell 1, a round seat section 1212 is provided on the top of the transition section 1211, a T-shaped joint 1213 is provided on the top of the round seat section 1212, and an annular mounting opening 1214 for mounting the transmission mechanism 14 is formed between the T-shaped joint 1213 and the round seat section 1212. The mounting seat body 122 includes a top seat section 1221 nested with the rotating seat body 121, a threaded interface section 1222 is provided on the top of the top seat section 1221, and a circle of sealing gasket 125 is provided on the top surface of the top seat section 1221. Among them, the transition section 1211 is connected to the two sides of the shell 1 in an arc transition manner. The circular seat section 1212 provides the most basic circular installation part for the lamp holder 12. The T-joint 1213 and the top seat section 1221 are nested to complete the sealing of the transmission mechanism 14, so that the transmission mechanism 14 has better transmission sealing conditions between the rotating seat body 121 and the mounting seat body 122. The lamp holder 12 as a whole is connected to the screw seat in the installation scenario of this equipment through the threaded interface section 1222. After the mounting seat body 122 and the screw seat are assembled, they remain relatively fixed, and the rotating seat body 121 is internally driven by the servo motor 13 and the transmission mechanism 14 to achieve relative rotation with the mounting seat body 122.

[0041] In order to improve the transmission performance of the transmission mechanism 14 and its adaptability with the rotating seat body 121 and the mounting seat body 122, as shown in FIG. Figure 6-Figure 9As shown, the transmission mechanism 14 provided by the present invention includes a pair of input gears 141 arranged in the installation port 1214, and a transmission shaft 142 is provided at the center of the input gear 141 for transmission connection with the servo steering engine 13. The transmission side of the input gear 141 is provided with a ring gear 143 that meshes with the two input gears 141 at the same time. The ring gear 143 is fixedly connected to the inner wall of the top seat section 1221, and a plurality of positioning screws 144 distributed in a circular array are provided on the side of the top seat section 1221. The positioning screws 144 are movably engaged with the annular positioning groove 145 provided on the circular seat section 1212. Among them, the positioning screw 144 is inserted into the positioning groove 145 from the radial direction to define the axial relationship between the rotating seat body 121 and the mounting seat body 122 without affecting the reciprocating rotation of the rotating seat body 121; one end of the transmission shaft 142 is connected to the servo steering engine 13 for transmission, and the other end thereof passes through the shaft eye opened on the T-shaped joint 1213, and the shaft eye bearing can be set in the shaft eye. The two transmission shafts 142 are driven simultaneously by two relatively independent servo steering engines 13, which ensures the meshing of the two input gears 141 and the ring gear 143. The gear ring 143 maintains a relatively fixed relationship with the mounting base body 122 because it is meshed with the input gear 141. Therefore, the input gear 141 can drive the rotating base body 121 to rotate back and forth along the meshing path of the input gear 141 and the gear ring 143, thereby realizing the relative rotation of the rotating base body 121 and the mounting base body 122, thereby ensuring that the lighting unit, the color lamp 7 and the housing 1 can perform reciprocating rotation within a certain angle range under emergency adjustment, so as to achieve better emergency lighting effect and security effect.

[0042] In order to improve the stability of the relative rotation process between the rotating seat body 121 and the mounting seat body 122, as shown in FIG. Figure 8 and Figure 9 As shown, a buffer pad 19 is provided between the rotating base 121 and the mounting base 122 of the present invention. The buffer pad 19 comprises a cylindrical pad 191, the outer side of which is provided with a spiral groove 192 extending along its length. The buffer pad is made of rubber material, and its upper and lower end surfaces are designed with a smooth surface to ensure that they do not generate significant friction with the lamp holder 12. The bottom surface of the pad 191 supports the surface of the mounting opening 1214, and the top surface of the pad 191 supports the bottom surface of the meshing path between the input gear 141 and the ring gear 143. If the input gear 141 and the ring gear 143 experience slight oscillation in the meshing path, the pad can undergo a certain elastic deformation and quickly restore balance. This ensures the dynamic balance of the rotating base 121 and the mounting base 122 during relative rotation, thereby improving the operating performance of the lighting device in emergency rotation situations and ensuring that the service life of the device approaches its design life.

[0043] like Figure 3 and Figure 9As shown, to improve the device's overall form factor, the width of the housing 1 provided by the present invention gradually narrows from its ends to its middle position. The middle portion of the housing 1 is used to mount the servo actuator 13. The housing 1, mounting tube 6, rotating base 121, and shaft cylinder 8 are integrally formed. A pair of vertical through-plate screws 20 are provided at each end of the housing 1 for connecting the light panel 3. In this way, the housing 1 and the other integrally formed parts form a single assembly, and other structures can be directly assembled on the assembly, which helps to improve the connection reliability of the device components and the relative sealing of the internal environment of the housing 1.

[0044] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
