Description

Technical Field

[0001] This invention relates to the field of lighting electrical appliances, and more specifically, to a high- and low-beam integrated luminaire with anti-aircraft function. Background Technology

[0002] Traditional vehicle lighting typically consists of separate high beam and low beam units, each independently controlled by circuitry to provide high and low beam illumination. Because the high and low beam units are independent components and controlled separately, the overall structure of the vehicle lighting system is complex, with numerous components, resulting in increased size and weight, requiring significant installation space, and incurring high production and assembly costs.

[0003] Currently, only special-purpose vehicles possess nighttime air defense capabilities. However, these special-purpose vehicles, like ordinary vehicles, use separate high-beam and low-beam headlight assemblies. Ordinary vehicles, on the other hand, do not have nighttime air defense capabilities. With technological advancements, for reasons of outdoor safety and privacy protection, ordinary vehicles may also need to possess air defense capabilities in the future.

[0004] CN216790072U discloses an integrated lighting fixture and a special vehicle equipped with such a fixture. The fixture includes a lamp body, a light module housed within the lamp body, a lamp cover on top of the lamp body, and a power board connected to the light module inside the lamp body. The power board controls the operating state of the light module. The light module includes a low beam module, a high beam module arranged parallel to the low beam module, an anti-aircraft light module located on one side of the lamp body, and a daytime running light module on the opposite side. Each light module is connected to the power board via wiring inside the lamp body, forming an integrated lighting fixture. By rationally integrating multiple lighting modules into the lamp body, the size and weight of the lighting fixture are reduced, and numerous blind spots are avoided within the lamp body. The lamp body is sealed to the outside to prevent dirt or stones from entering and affecting the lamp body. This solves the problem of limited space in vehicle lighting fixtures, resulting in a more aesthetically pleasing fixture and reduced load.

[0005] However, the integrated lighting fixture still uses separate low beam, high beam, anti-aircraft light, and daytime running light modules, with each module connected to the power board via internal wiring. Therefore, the fixture is simply a combination of stacked modules, resulting in a complex overall structure with numerous components and high production and assembly costs. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problems to at least some extent.

[0007] The purpose of this invention is to provide a simple and compact integrated high and low beam lamp with air defense function that allows for flexible switching between high and low beams for vehicles.

[0008] The technical solution adopted by this invention to solve its technical problem is: a high-beam and low-beam integrated lamp with air defense function, comprising: a lamp housing, the lamp housing including a shell and a cover, the cover being a hollow structure and having a transparent shield, the transparent shield sealing the cover, and the cover sealing the shell; a reflector, the reflector being fixed inside the shell, the reflector being an integrated structure and having a low beam cup and a high beam cup, the low beam cup and the high beam cup respectively having a light source, the low beam cup having a low beam reflecting surface, the light source of the low beam cup being reflected by the low beam reflecting surface to form low beam, the high beam cup having a high beam reflecting surface, the light source of the high beam cup being reflected by the high beam reflecting surface to form high beam; an air defense cover, the air defense cover being fixed on the cover, the air defense cover having a light shield and having a low beam light outlet and a high beam light outlet, the low beam cup facing the transparent shield and the low beam light outlet and together forming a low beam channel, the high beam cup facing the transparent shield and the high beam light outlet and together forming a high beam channel.

[0009] In use, when the luminaire is used for low beam illumination, only the low beam reflector works, reflecting the light through its reflective surface to form low beam. When the luminaire is used for high beam illumination, the high beam reflector is controlled to emit light, working in conjunction with the low beam reflector to add high beam reflection on top of the low beam. The reflector is a single unit, utilizing the principles of low and high beam to emit both, and allowing for flexible switching. Therefore, this invention is an integrated low and high beam system, eliminating the need for separate low and high beam modules, greatly simplifying the overall luminaire structure. Its simple and compact design effectively reduces production and assembly costs.

[0010] When air defense is required, an air defense cover is added to the lamp housing, utilizing its light-shielding cap to increase the vehicle's concealment at night. It features separate low-beam and high-beam outputs, eliminating the need for a separate air defense lamp module and simplifying the structure. This effectively combines integrated high / low beam switching with air defense functionality, making it convenient to use. If air defense is not required, the air defense cover can be removed from the housing, offering flexibility.

[0011] In a preferred embodiment, the length of the low beam output port is greater than that of the high beam output port, and the low beam output port and the light shield are integrated. Since the low beam output port is longer than the high beam output port, the low beam output port itself can function as a light shield; therefore, integrating the low beam output port and the light shield further simplifies the structure. Directly using the low beam output port as a light shield only requires a sufficient length to achieve both light shielding and anti-aircraft effects.

[0012] In a preferred embodiment, the high beam output port is provided with an adjustment baffle, which is rotatably fixed to the high beam output port. The adjustment baffle can be rotated to remain in the open state to activate the high beam in an air defense situation; it can also be kept in the closed state under certain circumstances to use only the low beam output.

[0013] More preferably, the adjusting baffle is provided with a locking block, and the side of the low beam output port facing the adjusting baffle is provided with a fastener, so that the adjusting baffle can be fixed to the low beam output port by a locking mechanism. Fixing the adjusting baffle to the low beam output port by a locking mechanism allows the adjusting baffle to remain in the open state for a long time, which is convenient for high beam output in air defense situations.

[0014] In a preferred embodiment, a first sealing ring is provided between the housing cover and the transparent cover. The first sealing ring is a C-shaped sealing ring that fits around the transparent cover. The end of the first sealing ring is bent and extended towards the transparent cover to form an inclined circumferential surface, which fits snugly against the transparent cover. The first sealing ring, fitted around the transparent cover, forms a seal between the housing cover and the transparent cover, effectively preventing internal leakage and improving the overall waterproof performance of the lamp, thus protecting the internal components and extending the lamp's lifespan. Furthermore, the bent and extended end of the first sealing ring to form an inclined circumferential surface increases the sealing area with the transparent cover, further enhancing the waterproof effect.

[0015] In a preferred embodiment, the housing has an insertion hole and an insertion hole. The insertion hole is inserted into the insertion hole. A second sealing ring is provided between the housing and the insertion hole. The housing has a planar sealing groove. The second sealing ring is a planar sealing ring and is fitted into the planar sealing groove. The second sealing ring forms a planar seal with both the housing and the insertion hole. The insertion hole is used to connect to a power source. The second sealing ring forms a seal between the housing and the insertion hole, providing a safe and secure seal for the connection, preventing leakage, and improving the safety and reliability of use. Since the contour surface of the housing may be an uneven curved surface, a planar sealing groove is provided in the housing to avoid affecting the sealing effect. The second sealing ring is a planar sealing ring and is fitted into the planar sealing groove to form a planar seal. This allows both sides of the second sealing ring to fit more closely with the housing and the insertion hole, increasing the sealing area and further enhancing the sealing effect.

[0016] In a preferred embodiment, the housing is provided with U-shaped rotating brackets on both sides. Each U-shaped rotating bracket includes a fixed base plate and mounting side plates located on either side of the fixed base plate, with the fixed base plate having a larger area than the mounting side plates. The U-shaped rotating brackets are rotatably fixed to both sides of the housing, facilitating lamp adjustment and installation. The larger area of ​​the fixed base plate increases the contact area with the vehicle body during installation, facilitating effective lamp fixation, preventing lamp loosening, and thus improving lamp stability.

[0017] More preferably, the fixed base plate is provided with first oblong holes on both sides, and the curvature of the first oblong holes is 16°. The first oblong holes facilitate the rotation and adjustment of the fixed base plate, thereby adjusting the illumination angle of the entire lamp left and right. Setting the curvature of the first oblong holes to 16° means that, with the center line of the first oblong holes as a reference, the illumination angle can be adjusted left and right within a large angle range of ±8°, which is convenient for installation and use. Of course, in other embodiments, the curvature of the first oblong holes can be designed to other angles according to the installation and use occasion and illumination adjustment needs.

[0018] More preferably, the mounting side plates on both sides are provided with second oblong holes side by side, and the curvature of the second oblong holes is 40°. The second oblong holes facilitate the rotation and adjustment of the mounting side plates, thereby adjusting the illumination angle of the entire lamp vertically. Setting the curvature of the second oblong holes to 40° means that, with the center line of the second oblong holes as a reference, the illumination angle can be adjusted vertically within a large angle range of ±20°, which is convenient for installation and use. Of course, in other embodiments, the curvature of the second oblong holes can be designed to other angles according to the installation and use occasion and illumination adjustment needs.

[0019] More preferably, reinforcing inclined plates are provided between the fixed base plate and the mounting side plates on both sides. The reinforcing inclined plates form an angled support between the fixed base plate and the mounting side plates, which can increase the overall strength of the U-shaped rotating bracket and facilitate long-term use.

[0020] The beneficial effects of this invention are: compared with the prior art,

[0039] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate the embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figures 1 to 6As shown, the present invention provides a high-beam and low-beam integrated luminaire 100 with air defense function, comprising: a lamp housing, a reflector 101, and an air defense cover 102. Of course, the luminaire also includes other components such as a driver, which are not described in detail here as they are irrelevant to the design focus of this invention.

[0042] The lamp housing includes a housing 103 and a cover 104. The cover 104 is a hollow structure and is provided with a transparent shield 105. In this embodiment, the transparent shield 105 is preferably a glass shield. The transparent shield 105 seals the cover 104, and the cover 104 seals the housing 103.

[0043] The reflector 101 is fixed inside the housing 103. The reflector 101 is an integral structure and includes a low beam reflector 106 and a high beam reflector 107. In this embodiment, two low beam reflectors 106 and one reflector 107 are designed as needed. Both the low beam reflector 106 and the high beam reflector 107 are equipped with light sources 108. The bottoms of the low beam reflector 106 and the reflector 107 are respectively provided with light source slots 109, and the light sources 108 are respectively fitted into the light source slots 109. The low beam reflector 106 has a low beam reflecting surface 110, and the light source of the low beam reflector 106 is reflected by the low beam reflecting surface 110 to form low beam. The high beam reflector 107 has a high beam reflecting surface 111, and the light source of the high beam reflector 107 is reflected by the high beam reflecting surface 111 to form high beam.

[0044] The air raid shield 102 is detachably fixed to the cover 104 by screws. The air raid shield 102 is provided with a light-shielding cover and a low beam output port 112 and a high beam output port 113. The low beam cup 106 faces the transparent cover 105 and the low beam output port 112, and together they form a low beam channel, along which low beam is emitted. The high beam cup 107 faces the transparent cover 105 and the high beam output port 113, and together they form a high beam channel, along which high beam is emitted.

[0045] In use, when the lamp 100 is used for low beam illumination, only the light source of the low beam reflector 106 operates, and the low beam is reflected by the low beam reflector surface 110 of the low beam reflector 106 to form low beam. When the lamp 100 is used for high beam illumination, the light source of the high beam reflector 107 is controlled to emit light, working together with the light source of the low beam reflector 106, adding high beam formed by reflection from the high beam reflector surface 111 on top of the low beam. The reflector 101 is an integrated structure, utilizing the principles of low beam and high beam to emit both low beam and high beam with a single reflector, and the switching can be flexibly controlled. Therefore, this invention is an integrated low and high beam system, eliminating the need for separate low beam and high beam modules, greatly simplifying the overall structure of the lamp, resulting in a simple and compact structure that effectively reduces production and assembly costs.

[0046] When air defense is required, an air defense cover 102 is added to the cover 104 of the lamp housing. The air defense cover 102's light shield provides sufficient illumination, increasing the vehicle's concealment at night. Furthermore, it features a low beam output port 112 and a high beam output port 113 to emit low and high beams respectively, eliminating the need for a separate air defense lamp module and simplifying the structure. This effectively combines integrated high and low beam switching with air defense functionality, making it convenient to use. If air defense is not required, the air defense cover 102 can be removed from the cover 104, offering flexibility.

[0047] like Figure 5 As shown, in this embodiment, the length of the low beam output port 112 is greater than that of the high beam output port 113, and the low beam output port 112 is integrated with the light shield. Since the length of the low beam output port 112 is greater than that of the high beam output port 113, the low beam output port 112 itself can function as a light shield. Therefore, integrating the low beam output port 112 with the light shield further simplifies the structure. By directly using the low beam output port 112 as a light shield, only a sufficient length is needed to achieve both light shielding and anti-aircraft effects.

[0048] In this embodiment, the high beam output port 113 is provided with an adjustment baffle 114, which is rotatably fixed to the high beam output port 113. The adjustment baffle 114 can be rotated to remain in the open state to activate the high beam in an air defense situation; it can also be kept in the closed state under certain circumstances to use only the low beam output.

[0049] In this embodiment, the adjusting baffle 114 is provided with a locking block 115, and the side of the low beam output port 112 facing the adjusting baffle 114 is provided with a fastener 116. The adjusting baffle 114 can be fixed to the low beam output port 112 by a locking mechanism. Fixing the adjusting baffle 114 to the low beam output port 112 by a locking mechanism allows the adjusting baffle 114 to remain in an open state for a long time, facilitating high beam output during air defense operations.

[0050] like Figure 2 , Figure 7 As shown, in this embodiment, a first sealing ring 117 is provided between the cover 104 and the transparent cover 105. The first sealing ring 117 is a C-shaped sealing ring and is fitted around the transparent cover 105. The end of the first sealing ring 117 is bent and extended towards the transparent cover 105 to form an inclined circumferential surface 118, which fits against the transparent cover 105. The first sealing ring 117, fitted around the transparent cover 105, forms a seal between the cover 104 and the transparent cover 105, which can prevent internal leakage, improve the overall waterproof performance of the lamp, effectively protect the various components inside the housing 103, and extend the service life of the lamp. In addition, the inclined circumferential surface 118 formed by the bending extension of the end of the first sealing ring 117 can increase the sealing area that fits against the transparent cover 105, further enhancing the waterproof effect.

[0051] In this embodiment, the first sealing ring 117 is a C-shaped silicone sealing ring with a hardness of 50±5° and a C-shaped sealing groove height of 6.8mm. The height of the first sealing ring 117 before compression is 4mm, and the height after compression is 2.8mm. Therefore, the compression rate is controlled at >20%, which meets the sealing requirements.

[0052] like Figure 8 As shown, in this embodiment, the housing 103 is provided with a flight connector hole 119 and a flight connector 120. The flight connector 120 is inserted into the flight connector hole 119. A second sealing ring 121 is provided between the housing 103 and the flight connector 120. The housing 103 is provided with a planar sealing groove 122. The second sealing ring 121 is a planar sealing ring and is fitted into the planar sealing groove 122. The second sealing ring 121 forms a planar seal with the housing 103 and the flight connector 120 respectively. The flight connector 120 is used to connect to a power source. The second sealing ring 121 forms a seal between the housing 103 and the flight connector 120, providing a sealed safety guarantee for the connection line, avoiding leakage, and improving the safety and reliability of use. Since the contour surface of the housing 103 may be an uneven curved surface, in order to avoid affecting the sealing effect, a planar sealing groove 122 is provided in the housing 103, and the second sealing ring 121 is a planar sealing ring and is stuck in the planar sealing groove 122 to form a planar seal, so that the two sides of the second sealing ring 121 fit more closely with the housing 103 and the insert 120, increasing the sealing area and further enhancing the sealing effect.

[0053] In this embodiment, the second sealing ring 121 is a planar silicone sealing ring with a hardness of 50±5° and a thickness of 2mm. It is compressed by four M3 screws, and the screw torque is set to control the compression rate to >20% to achieve the sealing requirements.

[0054] like Figure 2 , Figure 9 As shown in this embodiment, the housing 103 is provided with U-shaped rotating brackets 123 on both sides. Each U-shaped rotating bracket 123 includes a fixed base plate 124 and mounting side plates 125 located on both sides of the fixed base plate 124. The area of ​​the fixed base plate 124 is larger than that of the mounting side plates 125. The U-shaped rotating brackets 123 are rotatably fixed to both sides of the housing 103, facilitating the adjustment and installation of the lamp. The larger area of ​​the fixed base plate 124 increases the contact area with the vehicle body during installation, facilitating effective fixation of the lamp, preventing loosening, and thus improving the stability of the lamp.

[0055] like Figure 9 , Figure 10As shown, in this embodiment, the fixed base plate 124 has first oblong holes 126 on both sides, and the curvature of the first oblong holes 126 is 16°. The first oblong holes 126 facilitate the rotation and adjustment of the fixed base plate 124, thereby adjusting the illumination angle of the entire lamp left and right. Setting the curvature of the first oblong holes 126 to 16° means that, with the center line of the first oblong holes 126 as a reference, the illumination angle can be adjusted left and right within a large angle range of ±8°, which is convenient for installation and use. Of course, in other embodiments, the curvature of the first oblong holes 126 can be designed to other angles according to the installation and use occasion and illumination adjustment needs.

[0056] In this embodiment, the mounting side plates 125 on both sides are respectively provided with second oblong holes 127 side by side, and the curvature of the second oblong holes 127 is 40°. The second oblong holes 127 facilitate the rotation and adjustment of the mounting side plates 125, thereby adjusting the illumination angle of the entire lamp vertically. Setting the curvature of the second oblong holes 127 to 40° means that, with the center line of the second oblong holes 127 as a reference, the illumination angle can be adjusted vertically within a large angle range of ±20°, which is convenient for installation and use. Of course, in other embodiments, the curvature of the second oblong holes 127 can be designed to other angles according to the installation and use occasion and illumination adjustment needs.

[0057] In this embodiment, reinforcing inclined plates 128 are respectively provided between the fixed base plate 124 and the mounting side plates 125 on both sides. The reinforcing inclined plates 128 form an angled support between the fixed base plate 124 and the mounting side plates 125, which can increase the overall strength of the U-shaped rotating bracket 123 and facilitate long-term use.
