Description

Technical Field

[0001] This invention relates to energy-saving lighting equipment technology, specifically an energy-saving street lamp housing assembly. Background Technology

[0002] Energy-saving LED lights are commonly used for road lighting because they provide brighter illumination than conventional lamps, making them particularly suitable for use in highway tunnels. However, the energy-saving LED streetlights used in highway tunnels are quite complex due to the specific functions they serve.

[0003] For example, the publication (announcement) number: CN111895311B, publication (announcement) date: 2022-07-26, discloses an LED street light for warning in municipal tunnels, including a directional light holder and a lighting light holder. The surface of the directional light holder has an annular wiring hole, and a power connector is provided inside the annular wiring hole. Directional light mounting slots are provided on both sides of the annular wiring hole. LED small colored lights are fixedly connected to the inner wall of the directional light mounting slots. An upper connecting strip and a lower connecting strip are provided on both sides of the directional light holder, and a connecting hole is provided on the surface of both the upper connecting strip and the lower connecting strip. Fixing bolt holes are provided on both sides of the surface of the lighting light holder, and fastening bolts are threadedly connected to the inner side of the fixing bolt holes.

[0004] The shortcomings of existing technology lie in the fact that, due to the special nature of highways, streetlights are typically not installed on normal, flat roads to reduce the cost of lighting fixtures. However, for safety reasons, appropriate warning lights and streetlights must be installed inside highway tunnels and at their entrances. Furthermore, the suitable temperature and humidity inside tunnels attract large numbers of phototactic flying insects, as well as mosquitoes and other insects in the food chain, creating a poor working environment for maintenance. Additionally, streetlights inside tunnels become sticky with insect residue and dead insects due to impacts, accumulating a thick layer of insect residue over time. This significantly reduces the light transmittance of the streetlights, leading to decreased brightness. The corrosive liquids in the insect residue further erode the streetlights in high humidity, affecting heat dissipation from the streetlight casing, increasing the operating temperature of the LED chips, and thus affecting their lifespan. Corrosion can also create gaps in the sealing of the streetlight enclosure, allowing humidity to penetrate and further damaging the internal components. When cleaning streetlights inside tunnels manually, the poor working environment can affect the maintenance and cleaning cycle. In addition, for the sake of road traffic safety, maintenance is usually carried out at night, and the lights need to be powered off during cleaning, which increases the difficulty of maintenance and cleaning and reduces the efficiency of construction operations. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving street light housing assembly to address the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An energy-saving street light housing assembly includes an inner housing for mounting LED lamp bead plates and ultraviolet lamp bead plates facing each other, and two symmetrically distributed hangers are fixedly installed on the outer wall of the inner housing; It also includes an outer lamp housing located on the outside of the inner lamp housing and fixed by two hanging brackets, wherein the outer lamp housing is provided with two concave plates; An arc shield is fixedly installed on the hanger, maintaining a predetermined distance from the concave plate, and a retention chamber is formed between the arc shield and the concave plate; An airway communicating with the retention chamber is formed between the two hangers.

[0007] As a further description of the above technical solution: an air guide is provided between the LED lamp bead plate and the ultraviolet lamp bead plate, which abuts against the inner wall of the inner lamp housing.

[0008] As a further description of the above technical solution: a light-transmitting reflective plate is provided between the two concave plates, which is located in the light path of the ultraviolet light bead plate.

[0009] As a further description of the above technical solution: the outer lamp housing is provided with a light cavity located outside the inner lamp housing.

[0010] As a further description of the above technical solution: it also includes a platform-shaped mesh shell disposed at the end of the inner lamp housing and communicating with the light cavity.

[0011] As a further description of the above technical solution: the concave plate is provided with an air outlet in the middle for connecting the optical cavity and the retention chamber.

[0012] As a further description of the above technical solution: the two ends of the arc shield are provided with cuts that are diagonally opposite to each other and connected to the airway.

[0013] As a further description of the above technical solution: the arc shield has a vent in the middle that is connected to the air outlet.

[0014] As a further description of the above technical solution: the hanger is hinged in the middle and has a flap for exhausting air.

[0015] As a further description of the above technical solution: the flap is driven to deflect at a predetermined angle, so that the optical cavity and the air channel are connected and cooperated.

[0016] In the above technical solution, the energy-saving street light housing assembly provided by this invention has the following beneficial effects: By using an outer lamp housing combined with a platform-shaped mesh shell to provide all-round shielding and protection for the inner lamp housing, the contamination caused by flying insects near the light source is greatly reduced. Ultraviolet light is used to attract flying insects to the tunnel wall, reducing the direct attraction of insects to LED light. The heat transferred from the hanger causes heat-attracting insects to stay at the two concave plates, thereby reducing insect residue and dead insects at the curved lamp plate location, effectively ensuring the lighting brightness of the LED light-transmitting area and reducing corrosion on the curved lamp plate surface. Some flying insects crawl into the retention chamber through the gaps on both sides of the curved shield to get closer to the light source, causing them to accumulate in the retention chamber until their movement is restricted, or even suffocating them, reducing the possibility of insects crawling to the curved lamp plate after landing.

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-13 The present invention provides a technical solution: an energy-saving street light housing assembly, including an inner lamp housing 1 for mounting LED lamp bead plates 21 and ultraviolet lamp bead plates 22 facing each other, and two symmetrically distributed hangers 3 are fixedly installed on the outer wall of the inner lamp housing 1; It also includes an outer lamp housing 4 located on the outside of the inner lamp housing 1 and fixed by two hangers 3, with two recessed plates 43 on the outer lamp housing 4; An arc shield 6 is fixedly installed on the hanger 3, maintaining a predetermined distance from the concave plate 43, and a retention chamber 431 is formed between the arc shield 6 and the concave plate 43. An airway 30 is formed between the two hangers 3, which communicates with the retention chamber 431.

[0022] Specifically, the inner lamp housing 1 is made of aluminum alloy or thermally conductive plastic for lighting fixtures, and has symmetrically distributed notches. A tempered glass flat lamp plate 11 is bolted into these notches, allowing the LED lamp bead board 21 and the ultraviolet lamp bead board 22 to each transmit light through the flat lamp plate 11, resulting in the ultraviolet light and LED light illuminating each other in opposite directions. Therefore, the ultraviolet light can illuminate the tunnel wall, preventing people in vehicles from directly seeing the ultraviolet light.

[0023] Furthermore, the base shells of the inner lamp housing 1 and the outer lamp housing 4 are composed of cylindrical circles, and the two are coaxially arranged. For example... Figure 10As shown, the outer lamp housing 4 is integrally molded from polycarbonate and acrylic materials. The arc lamp plate 41 is the light-transmitting plate with the largest arc area on the outer lamp housing 4, and it is positioned on the LED light path to ensure that the light used for road lighting has an excellent diffusion range. The two concave plates 43 are symmetrical and recessed towards the axis to form the space required for the retention chamber 431. The concave plates 43 are provided with holes for the brackets 31 to pass through, so that the outer lamp housing 4 can be installed in a limited position through the four brackets 31, ensuring the stability of the outer lamp housing 4 during use.

[0024] Furthermore, the cross-section of the hanger 3 is V-shaped, and the V-shaped protrusions of the two hangers 3 are arranged facing each other, thus giving the air duct 30 a symmetrical Venturi structure. Therefore, regardless of which side the airflow blowing through the tunnel wall comes from, one of the Venturi structures remains operational to increase the flow velocity inside the air duct 30. A mounting plate 32 is welded to one side of the hanger 3, and the mounting plate 32 has multiple threaded holes for drilling into the tunnel wall for installation. Before fixing, the mounting plate 32 needs to be affixed or fitted with anti-slip pads to ensure anti-slip function after installation and to adapt to the curved installation position of the tunnel wall, ensuring the stability of the hanger 3 after fixing. Two brackets 31 are welded to the other side of the hanger 3, such as... Figure 8 As shown, the bracket 31 is installed with bolts to the lamp holder 12 integrally formed on the inner lamp housing 1. Therefore, the heat absorbed by the inner lamp housing 1 is easily transferred to the hanger 3 through the bracket 31, and the airflow also facilitates the heat dissipation of the two hangers 3.

[0025] Furthermore, such as Figure 12 As shown, the arc shield 6 has a V-shaped hole for the hanger 3 to pass through. Both ends of the arc shield 6 are integrally formed with side plates 61 that seal the sides of the retention chamber 431. The side plates 61 maintain a predetermined gap with the inner wall of the concave plate 43, allowing some airflow to enter the retention chamber 431 through this gap, increasing the airflow rate. Bolts are then used to fix the side plates 61 and the ends of the hanger 3 (both have interconnected threaded holes), ensuring that the side walls of the arc shield 6 and the outer lamp housing 4 are on the same cross-sectional circle. This also facilitates the arc shield 6 to provide a stable cover over the outer side of the concave plate 43, ensuring the stable operation of the retention chamber 431.

[0026] The outer lamp housing 4 protects and stores the inner lamp housing 1, greatly reducing the contamination of the inner lamp housing 1 near the light source by flying insects. Ultraviolet light attracts flying insects to the tunnel wall, reducing the direct attraction of insects to the LED light. The heat transferred from the hanger 3 causes heat-seeking insects to stay at the two concave plates 43, thus reducing insect residue and dead insects at the arc lamp plate 41, effectively ensuring the illumination brightness of the LED light-transmitting area and reducing corrosion on the surface of the arc lamp plate 41. Some flying insects crawl into the retention chamber 431 through the gaps on both sides of the arc shield 6 to get closer to the light source, causing them to accumulate in the retention chamber 431 until their movement is restricted, or even suffocating them, reducing the likelihood of landing insects crawling to the arc lamp plate 41. When the tunnel airflow passes through the streetlight, the air velocity inside the air passage 30 increases due to the narrow tube effect and Venturi action. Some of the airflow enters the retention chamber 431 along the gaps, blowing out the trapped flying insects and their corpses, thus cleaning the retention chamber 431 and facilitating the re-accumulation and guidance of flying insects. Even though ultraviolet lamps specifically designed to trap flying insects have been installed in the tunnel, this solution addresses the issue that LED light still attracts flying insects by separately installing insect-attracting ultraviolet lamps at the relative positions of the LED lights. This allows individual streetlights to also have insect-proof protection, thereby maintaining the working efficiency and lifespan of the streetlights in the tunnel, while also reducing the maintenance requirements of the streetlights in the tunnel.

[0027] In another embodiment of the present invention, the heat emitted by the two LED chips is absorbed by the air guide 2, and the airflow inside the inner lamp housing 1 carries away the heat from the air guide 2, ensuring the safety of the working environment of the two LED chips. At the same time, some of the heat on the air guide 2 is transferred to the side wall of the inner lamp housing 1 through contact, causing the hanger 3 to perform heat conduction, realizing the transfer of heat to the outer lamp housing 4 and its use for attracting flying insects.

[0028] Specifically, the air guide 2 is composed of multiple aluminum heat dissipation fins distributed in layers and vertically assembled and welded together. After installation, the air guide 2 has two aluminum plates abutting against the back of the two LED bead plates. The inner lamp housing 1 has plates welded or integrally formed for mounting the two LED bead plates. The air guide 2 is installed in the inner lamp housing 1 by pre-inserting the plates before welding or by inserting the plates under pressure deformation.

[0029] In another embodiment of the present invention, a portion of the ultraviolet light passes directly through the light-transmitting reflector plate 42 to attract flying insects outside the outer lamp housing 4, while the other portion is reflected to the two concave plates 43. This further enhances the attraction of the retention chamber 431 to flying insects, based on the fact that the ultraviolet light was originally irradiated on the concave plates 43.

[0030] Specifically, the light-transmitting reflector 42 is integrally formed on the outer lamp housing 4, and the inner wall of the light-transmitting reflector 42 has multiple uneven reflective surfaces, and the reflective surfaces face the inner walls of the two concave plates 43. The way the reflective surfaces are set is existing technology and will not be described in detail here.

[0031] In another embodiment of the present invention, the optical cavity 40 ensures the spatial path for light to propagate from the two LED chips to the outer lamp housing 4, while also providing airflow within the optical cavity 40, thus giving the inner lamp housing 1 a larger air contact surface. This ensures the heat dissipation effect of the inner lamp housing 1 and reduces heat transfer to the arc lamp plate 41, effectively alleviating the situation where the arc lamp plate 41 attracts heat-attracting flying insects due to heat.

[0032] Specifically, the light cavity 40 is the area between the inner wall of the outer lamp housing 4 and the outer wall of the inner lamp housing 1, such as... Figure 4 and Figure 5 As shown, only two brackets 31 on the hanger 3 are located in the optical cavity 40, so the airflow in the optical cavity 40 is not easily blocked by a large area, ensuring the diffusion of airflow inside the optical cavity 40.

[0033] In another embodiment of the present invention, the truncated sidewalls of the truncated mesh shell 5 not only prevent flying insects from entering the light cavity 40, but also allow external airflow into the light cavity 40, thus satisfying the cooling and air circulation requirements of the outer side of the inner lamp shell 1. The sealing of the truncated mesh shell 5 facilitates the direct action of airflow on the air guide 2, thereby accelerating the dissipation of heat from the inner side of the inner lamp shell 1.

[0034] Secondly, by utilizing the converging function of the inner wall of the platform-shaped mesh shell 5, the airflow speed entering the inner lamp shell 1 from the seal is accelerated, thereby improving the cooling capacity of the air guide 2.

[0035] Specifically, the platform-shaped mesh shell 5 is made of aluminum alloy, with an opening at the larger end and a sealed end at the smaller end, covering the end of the inner lamp shell 1. Multiple round holes are provided along the edge of the opening for fixing to the end of the outer lamp shell 4 with bolts and nuts; multiple round holes are also provided on the seal for threaded fixing to the end of the inner lamp shell 1.

[0036] Furthermore, such as Figure 7 As shown, the middle section of the inner wall of the outer lamp housing 4 is obtuse-angled, so the inner wall of the outer lamp housing 4 also has the function of a venturi tube, which accelerates the airflow to the middle of the outer lamp housing 4.

[0037] In another embodiment of the present invention, the accelerated airflow can be blown toward the inner wall of the arc shield 6 through the air outlet 44, and then diffused from the inner wall of the arc shield 6 to the retention chamber 431. The airflow is then used to blow away the flying insects staying in the retention chamber 431, so that the flying insects are discharged from the gaps on both sides of the arc shield 6 or the gaps in the side plates 61, thereby reducing the blockage problem of the retention chamber 431 and improving the working efficiency of the retention chamber 431.

[0038] Specifically, the air outlet 44 is a platform-shaped pipe and protrudes in the concave plate 43. The purpose is to increase the height at which flying insects climb into the air outlet 44, making it difficult for flying insects to enter the light cavity 40 through the air outlet 44, and reducing the impact of the flying insect corpses on the light transmittance of the light cavity 40.

[0039] In another embodiment of the present invention, two obliquely distributed slits 62 on the arc shield 6 cause the two gaps to actively extend the path of airflow in and out, so that the airflow entering the retention chamber 431 has oblique blowing ability, which increases the cleaning effect on flying insects and also makes it easier for flying insects to be discharged from the larger gaps, reducing the risk of blockage.

[0040] Specifically, the cut 62 causes a larger gap to appear between the slit on one side of the arc shield 6 and the gap in the side plate 61, and makes the gap serve as a guide for flying insects to crawl in. It can also increase the airflow rate for rapid airflow in and out, and increase the airflow pressure inside the retention chamber 431.

[0041] In another embodiment of the present invention, the air volume discharged from the air outlet 44 is shared by the vent 63. The purpose is to effectively reduce the pressure generated by the airflow impacting the arc shield 6 when the air volume in the tunnel is too large, to avoid damage to the components caused by the excess air volume, and to reduce the impact on the stable operation of the hanger 3. At the same time, the increased air volume can also enhance the blowing ability of the retention chamber 431, and the cleaning effect can be improved while ensuring the stability of the components.

[0042] Specifically, the cross-section of the vent 63 is smaller than the end cross-section of the air outlet 44, and most of the airflow discharged from the air outlet 44 will enter the stagnation chamber 431, while a small portion will be discharged directly from the vent 63.

[0043] In another embodiment of the present invention, when the airflow in the airway 30 is too strong, the pressure impact causes the flap 34 to rotate. At this time, the flap 34 will immediately be impacted by the airflow discharged from the vent 63, and this airflow impact is greater than the pressure impact given by the airway 30, causing the flap 34 to remain in the deflected state, so that the vent 63 used for venting will replenish the airflow into the airway 30 for mixing, such as... Figure 6As shown, the purpose is to increase the gas flow rate in the airway 30, so that when the mixed airflow passes through the gap of the arc shield 6, the narrow tube effect is more significant, which can further improve the cleaning ability of the edge of the retention chamber 431 and the outer wall of the outer lamp housing 4 at the ultraviolet light illumination position.

[0044] Specifically, a frame opening 33 is provided in the middle of one side of the hanger 3, and the flap 34 is hinged in the frame opening 33, and the shape of the flap 34 is the same as the missing shape of the frame opening 33. A torsion spring is provided at the hinge position. In the default state, the torsion spring makes the flap 34 fit with the frame opening 33 to ensure that the air passage 30 is not affected by airflow branching when the hanger 3 is working normally.

[0045] Furthermore, the flap 34 has a rotation range of 0-60°, and within this range, the flap 34 will guide more airflow along its surface into the air passage 30, increasing the airflow velocity in the air passage 30. The sidewall of the vent 63 is located outside the end of the flap 34 in the fan-shaped motion trajectory, avoiding stroke interference of the flap 34 during the movement.

[0046] In another embodiment of the present invention, after the flap 34 is deflected by the vent 63, the deflection angle of the flap 34 changes accordingly as the flow rate of the airflow discharged from the vent 63 changes. Furthermore, the oblique compensation airflow between the flap 34 and the vent 63 in the airway 30 results in lower air pressure at the end of the flap 34 and on the other side of the vent 63, making it easier for external airflow to be drawn in by the oblique airflow inside the flap 34, further increasing the gas flow rate entering the airway 30. Simultaneously, as the temperature at the hanger 3 rises, thermal pressure is created, causing the low-temperature external air to flow more easily to the high-temperature area around the hanger 3, thereby increasing the airflow drawn into the airway 30 and resulting in more airflow compensated into the airway 30, effectively improving the cleaning effect. Moreover, the high flow rate in the airway 30 and the slow flow rate outside the arc lamp plate 41 create a pressure difference that firmly secures the lighting lamp, which helps enhance the stability of the streetlights when strong winds occur in the tunnel.

[0047] Working principle: Ultraviolet light is used to attract flying insects to the tunnel wall, reducing the direct attraction of insects to the LED light. The heat transferred from the hanger 3 causes heat-seeking insects to stay at the two concave plates 43, reducing insect residue and dead insects at the arc lamp plate 41, ensuring sufficient illumination at the LED light-transmitting area. Some insects crawl into the retention chamber 431 through the gaps on both sides of the arc shield 6 to get closer to the light source, causing them to accumulate and become restricted in movement, or even suffocate, reducing the likelihood of landing insects crawling to the arc lamp plate 41. When the tunnel airflow passes through the streetlight, the airflow velocity inside the air passage 30 increases due to the narrow tube effect and Venturi action. Some airflow enters the retention chamber 431 along the gaps, blowing out the trapped insects, thus clearing the retention chamber 431 and creating conditions for insects to accumulate and be guided back in.

[0048] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
