[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0021] like Figure 1-9 As shown, a temporary lighting street lamp for road construction comprises: Combined housing 2; The light source mechanism 1 comprises a low beam lamp panel 10 and a high beam lamp panel 11 connected to the bottom of the combined housing 2 along a horizontal sliding manner, and an inclined reflection plate 12 arranged on the combined housing 2 along a 45° inclination; The low beam lamp panel 10 and the high beam lamp panel 11 are driven to slide in the horizontal direction, and the brightness of the low beam lamp panel 10 is driven to decrease as the brightness of the high beam lamp panel 11 increases, and to increase as it decreases.

[0022] Specifically, the combined shell 2 includes an outer cover 21 and a chassis 23, and the inclined reflector 12 is inclined at 45° on the outer cover 21. The low beam lamp panel 10 and the high beam lamp panel 11 are slidably connected between the outer cover 21 and the chassis 23. When performing repair lighting on the road surface, a floodlight-focused illumination environment is required. At this time, the low beam lamp panel 10 and the high beam lamp panel 11 are pushed to slide in the horizontal direction, driving the brightness of the high beam lamp panel 11 to weaken, while the brightness of the low beam lamp panel 10 is increased, thereby enhancing the floodlight range, weakening the high beam effect, and diffusing the overall light scattering range. This is suitable for lighting the road surface. When excavating and repairing the pipelines under the road surface, the low beam lamp panel 10 and the high beam lamp panel 11 are pushed to slide in the horizontal direction, driving the brightness of the high beam lamp panel 11 to increase, while the brightness of the low beam lamp panel 10 is weakened, so as to illuminate the pipelines under the road surface, which is convenient for fine maintenance operations.

[0023] Furthermore, two light sources (i.e., the low beam lamp panel 10 and the high beam lamp panel 11) are horizontally arranged between the outer cover 21 and the chassis 23, and are intersected and overlapped through an inclined reflector plate 12 inclined at 45 degrees, thereby reducing heat generation and making the illumination more stable.

[0024] In the above technical scheme, the switching between floodlight and high beam, as well as the coexistence of the two are achieved by adjusting the brightness of the low beam lamp panel 10 and the high beam lamp panel 11. The high beam can be used for fine operation lighting such as pipeline connection during road maintenance, while the floodlight can also be used for road maintenance. The light is refracted and then transmitted by the inclined reflector 12, so that the light from the two light sources intersects and overlaps, reducing heat generation and making the illumination more stable. It also avoids active mechanical zoom structures, and can extend the service life of the lamp at sites with large amounts of dust.

[0025] As an embodiment provided by the present invention, the low beam lamp panel 10 or the high beam lamp panel 11 increases brightness as it slides in the horizontal direction close to the center line of the inclined reflective plate 12 .

[0026] Specifically, the low beam light board 10 is connected and fixed to the high beam light board 11 and can slide together. When it is necessary to enhance the floodlight range, the low beam light board 10 is moved horizontally toward the high beam light board 11, which will make the low beam light board 10 close to the center line of the inclined reflector plate 12. At the same time, the brightness of the light of the low beam light board 10 will be enhanced, while the brightness of the light of the high beam light board 11 will be weakened, so that the low beam light board 10 with strong light is moved close to the center line of the inclined reflector plate 12. When fine operation is required to perform targeted high beam irradiation, the low beam light board 10 is moved horizontally toward the low beam light board 10, so that the high beam light board 11 is moved close to the center line of the inclined reflector plate 12, and the intensity of the high beam light board 11 is enhanced. When there is a difference in the intensities of the low beam light board 10 and the high beam light board 11, the light source with strong light intensity is moved close to the center line of the inclined reflector plate 12, thereby avoiding the eccentricity of the light source point when the light is superimposed.

[0027] When an environment with focused floodlighting is required, the low beam light board 10 and the high beam light board 11 are pushed to move horizontally toward the high beam light board 11 so that the low beam light board 10 approaches the center line of the inclined reflector 12, driving the brightness of the high beam light board 11 to decrease. At this time, the brightness of the low beam light board 10 increases to illuminate the road surface. When excavating and repairing pipelines under the road surface, the low beam light board 10 and the high beam light board 11 are pushed to move horizontally toward the low beam light board 10 so that the high beam light board 11 approaches the center line of the inclined reflector 12, driving the brightness of the high beam light board 11 to increase. At this time, the brightness of the low beam light board 10 decreases to illuminate the pipelines under the road surface.

[0028] As an embodiment provided by the present invention, resistor bars 44 corresponding to the low beam lamp board 10 and the high beam lamp board 11 are symmetrically arranged in the combined shell 2, and contact points 101 electrically connected to the resistor bars 44 are arranged on the low beam lamp board 10 and the high beam lamp board 11.

[0029] Specifically, the resistor bar 44, the power supply, the low beam light board 10 and the high beam light board 11 are electrically connected. The low beam light board 10 and the high beam light board 11 are both provided with contact points 101. When the low beam light board 10 and the high beam light board 11 are driven to slide, the contact points 101 will slide along the resistor bar 44 to increase the path of the current passing through the resistor bar 44, thereby changing the brightness of the low beam light board 10 and the high beam light board 11.

[0030] Furthermore, a power supply is provided on the combined housing 2, and the power supply, the resistor bar 44, and the low beam lamp panel 10 and the high beam lamp panel 11 are electrically connected through cables, which belongs to the prior art and will not be described in detail.

[0031] When an environment with a focus on floodlighting is required, the low beam light board 10 and the high beam light board 11 are pushed to move horizontally toward the high beam light board 11 so that the low beam light board 10 is close to the center line of the inclined reflector 12. At the same time, the contact point 101 will slide along the resistor bar 44 to drive the brightness of the high beam light board 11 to decrease. At this time, the brightness of the low beam light board 10 is increased to illuminate the road surface. When excavating and repairing the pipelines under the road surface, the low beam light board 10 and the high beam light board 11 are pushed to move horizontally toward the low beam light board 10 so that the high beam light board 11 is close to the center line of the inclined reflector 12. At the same time, the contact point 101 will slide along the resistor bar 44 to drive the brightness of the high beam light board 11 to increase. At this time, the brightness of the low beam light board 10 is reduced to illuminate the pipelines under the road surface.

[0032] As an embodiment provided by the present invention, it also includes an adjustment mechanism 3, which includes a buckle plate 31 arranged on the low beam light board 10 and the high beam light board 11, the combined shell 2 includes a chassis 23, and an adjustment protrusion 32 is slidably connected to the chassis 23. A coupling gear 33 is arranged between the adjustment protrusion 32 and the buckle plate 31 to drive the low beam light board 10 and the high beam light board 11 to move.

[0033] Specifically, the buckle plate 31 is used to fix the low beam lamp board 10 and the high beam lamp board 11, the chassis 23 is arranged on the outer cover 21, and a support frame 331 is arranged on the chassis 23, the coupling gear 33 is rotatably connected to the support frame 331, the buckle plate 31 is provided with a tooth groove, the chassis 23 is provided with a slide groove 231, the adjustment protrusion 32 is slidably connected to the slide groove 231, and a tooth plate 321 is arranged on the adjustment protrusion 32, and the tooth plate 321 is coupled to the tooth groove on the buckle plate 31 through the coupling gear 33. When it is necessary to drive the low beam lamp board 10 and the high beam lamp board 11 to move, the adjustment protrusion 32 is toggled to slide, so as to drive the tooth plate 321 to drive the coupling gear 33 to flip to drive the buckle plate 31 to move, thereby driving the low beam lamp board 10 and the high beam lamp board 11 to slide in the horizontal direction, adjust the position and move the position to change the position of the contact resistance strip 44, and adjust the brightness.

[0034] When the floodlighting environment is required, the adjusting protrusion 32 is toggled to slide along the slide groove 231, and the tooth plate 321 drives the coupling gear 33 to flip to drive the buckle limit plate 31 to move, thereby pushing the low beam lamp panel 10 and the high beam lamp panel 11 to move horizontally toward the high beam lamp panel 11, so that the low beam lamp panel 10 is close to the center line of the inclined reflector plate 12. At the same time, the contact point 101 will slide along the resistor strip 44, driving the high beam lamp panel 11 to reduce the brightness of the light, while the low beam lamp panel 10 increases the brightness of the light. , for road lighting, and when the pipeline under the road is excavated and repaired, the adjusting protrusion 32 is pushed to slide along the slide groove 231, pushing the low beam lamp board 10 and the high beam lamp board 11 to move horizontally toward the low beam lamp board 10, so that the high beam lamp board 11 approaches the center line of the inclined reflector 12, and at the same time, the contact point 101 will slide along the resistor bar 44, driving the high beam lamp board 11 to increase the brightness of the light, while the low beam lamp board 10 will reduce the brightness of the light, so as to illuminate the pipeline under the road.

[0035] As an embodiment provided by the present invention, a soft light blocking plate 15 is horizontally arranged at both ends of the inclined reflective plate 12, and a dust partition plate 13 is inclinedly arranged. A heat flow channel 210 is clamped between the soft light blocking plate 15, the combined shell 2, the low beam light board 10 and the high beam light board 11, and the heat flow channel 210 is toward the bottom of the dust partition plate 13.

[0036] Specifically, the soft light blocking plate 15 is used to diffusely reflect the light emitted by the low beam lamp panel 10 and the high beam lamp panel 11, thereby promoting the superposition of the light, and the dust shield 13 is inclined to Figure 8 As shown, a heat flow channel 210 is formed between the soft light baffle plate 15, the combined housing 2, the low beam lamp panel 10 and the high beam lamp panel 11. The soft light baffle plate 15 will retain a certain amount of heat when diffusely reflecting light, and the low beam lamp panel 10 and the high beam lamp panel 11 will also generate heat when powered on. The heat flow merges along the outlet of the heat flow channel 210 (with Figure 8 As shown, the outlet is at the left end, and flows out toward the dust-isolating plate 13), and flows upward along the dust-isolating plate 13. The upward hot air will carry the dust upward, thereby reducing the amount of dust adhering to the dust-isolating plate 13, and preventing dust from falling. It is particularly suitable for dust generated by broken land during road construction.

[0037] When a floodlight-focused illumination environment is required, the adjusting protrusion 32 is toggled to slide along the slide groove 231, and the tooth plate 321 drives the coupling gear 33 to flip to drive the buckle limit plate 31 to move, thereby pushing the low beam lamp panel 10 and the high beam lamp panel 11 to move horizontally toward the high beam lamp panel 11, so that the low beam lamp panel 10 is close to the center line of the inclined reflector plate 12. At the same time, the contact point 101 will slide along the resistor bar 44, driving the high beam lamp panel 11 to reduce the brightness of the light, while the low beam lamp panel 10 increases the brightness of the light, so as to illuminate the road surface. When excavating and repairing the pipeline under the road surface, the adjusting protrusion 32 is toggled to slide along the slide groove 231, and the tooth plate 321 drives the coupling gear 33 to flip to drive the buckle limit plate 31 to move. The protrusion 32 slides along the slide groove 231, pushing the low beam light board 10 and the high beam light board 11 to move horizontally toward the low beam light board 10, so that the high beam light board 11 approaches the center line of the inclined reflector 12. At the same time, the contact point 101 will slide along the resistor bar 44, driving the high beam light board 11 to increase the brightness of the light, while the brightness of the low beam light board 10 will decrease at this time to illuminate the pipes under the road surface. When the low beam light board 10 and the high beam light board 11 are lit, the heat flow generated will form an ascending heat flow, and the heat flows will merge and flow out along the outlet of the heat flow channel 210, and flow up along the dust partition plate 13, entraining the dust and flowing away.

[0038] As an embodiment provided by the present invention, a bottom strip 41 is fixedly connected to the chassis 23 via a spring 43, a resistor strip 44 is disposed on the bottom strip 41, and the spring 43 pushes against the bottom strip 41 to drive the resistor strip 44 to fit the contact point 101; A top strip 42 is fixedly connected to the soft light blocking plate 15 via a spring 43 , and the top strip 42 fits the low beam lamp panel 10 and the high beam lamp panel 11 .

[0039] Specifically, a bottom strip 41 is fixedly connected to the chassis 23 through a spring 43, and a resistor strip 44 is arranged on the bottom strip 41. The bottom strip 41 is pushed by the spring 43 to fit the bottom of the low beam lamp panel 10 and the high beam lamp panel 11, and drives the contact point 101 to always fit the resistor strip 44, so as to avoid the vibration generated during road construction from affecting the contact between the contact point 101 and the resistor strip 44, and the top strip 42 is also fitted to the top of the low beam lamp panel 10 and the high beam lamp panel 11 through the spring 43, so that the low beam lamp panel 10 and the high beam lamp panel 11 are supported by two groups of springs 43, thereby increasing the shock absorption capability.

[0040] When an environment with a focus on floodlighting is required, the adjusting protrusion 32 is toggled to slide along the slide groove 231, and the tooth plate 321 drives the coupling gear 33 to flip to drive the buckle limit plate 31 to move, thereby pushing the low beam lamp panel 10 and the high beam lamp panel 11 to move horizontally toward the high beam lamp panel 11, so that the low beam lamp panel 10 is close to the center line of the inclined reflector plate 12. At the same time, the contact point 101 will slide along the resistor bar 44, driving the brightness of the high beam lamp panel 11 to decrease, while the brightness of the low beam lamp panel 10 increases, and the road surface is illuminated. When the pipeline under the road surface is excavated and repaired, the adjusting protrusion 32 is toggled to slide along the slide groove 231, pushing the low beam lamp panel 10 and the high beam lamp panel 11 to move horizontally. Move toward the low beam light board 10 so that the high beam light board 11 approaches the center line of the inclined reflector plate 12. At the same time, the contact point 101 will slide along the resistor bar 44 to drive the high beam light board 11 to increase its brightness, while the low beam light board 10 will reduce its brightness to illuminate the pipes under the road surface. When the low beam light board 10 and the high beam light board 11 are lit, the heat flow generated will form an ascending heat flow. The heat flow merges and flows out along the outlet of the heat flow channel 210, and flows up along the dust partition plate 13, entraining the dust and flowing away. The vibration generated during road construction is damped by the two sets of springs 43, driving the contact point 101 to always fit the resistor bar 44 and protecting the low beam light board 10 and the high beam light board 11.

[0041] As an embodiment provided by the present invention, the combined housing 2 further includes a top oblique cover 22, on which a warning lamp cover 221 is provided, and the warning lamp cover 221 lights up as the brightness of the low beam lamp panel 10 decreases to a predetermined brightness; The predetermined brightness is when the brightness of the low beam lamp panel 10 is lower than that of the high beam lamp panel 11 .

[0042] Specifically, the top inclined cover 22 is arranged on the outer cover 21, and a warning lamp cover 221 is arranged on the top inclined cover 22. The warning lamp cover 221 is made of red or half-red and half-blue transparent plastic. As the adjustment protrusion 32 moves, the brightness of the low beam lamp panel 10 is continuously reduced, while the brightness of the high beam lamp panel 11 is continuously increased, until the brightness of the low beam lamp panel 10 is lower than that of the high beam lamp panel 11, the warning lamp cover 221 will light up to warn pedestrians and vehicles, so that when the floodlight is weakened and the illumination range of the surrounding roads is weakened, the surrounding pedestrians and vehicles are reminded by the lit warning lamp cover 221.

[0043] When the floodlighting environment is required, the adjusting protrusion 32 is toggled to slide along the slide groove 231, and the tooth plate 321 drives the coupling gear 33 to flip to drive the buckle limit plate 31 to move, thereby pushing the low beam lamp panel 10 and the high beam lamp panel 11 to move horizontally toward the high beam lamp panel 11, so that the low beam lamp panel 10 is close to the center line of the inclined reflector plate 12. At the same time, the contact point 101 will slide along the resistor strip 44, driving the high beam lamp panel 11 to reduce the brightness of the light, while the low beam lamp panel 10 increases the brightness of the light. , for road lighting, and when the pipeline under the road is excavated and repaired, the adjusting protrusion 32 is pushed to slide along the slide groove 231, pushing the low beam lamp board 10 and the high beam lamp board 11 to move horizontally toward the low beam lamp board 10, so that the high beam lamp board 11 approaches the center line of the inclined reflector 12, and at the same time, the contact point 101 will slide along the resistor bar 44, driving the high beam lamp board 11 to increase the brightness of the light, while the low beam lamp board 10 will reduce the brightness of the light, so as to illuminate the pipeline under the road.

[0044] In the process of increasing the high beam, when the brightness of the low beam panel 10 is lower than that of the high beam panel 11, the warning lamp cover 221 will light up to warn pedestrians and vehicles. When the low beam panel 10 and the high beam panel 11 are lit, the heat flow generated will form an upward heat flow. The heat flow merges and flows out along the outlet of the heat flow channel 210, and flows up along the dust partition board 13, carrying away the dust. The vibration generated during road construction is damped by two sets of springs 43, driving the contact point 101 to always fit the resistor bar 44, and protecting the low beam panel 10 and the high beam panel 11.

[0045] As the optimal embodiment provided by the present invention, a through groove 122 is provided on the inclined reflective plate 12 facing the warning light cover 221, and a movable reflective plate 14 is slidably connected to the top inclined cover 22. The movable reflective plate 14 is fixedly connected to the adjustment protrusion 32 to drive the movable reflective plate 14 to open or cover the through groove 122 as the adjustment protrusion 32 moves to adjust the brightness.

[0046] Specifically, a through groove 122 is opened on the inclined reflective plate 12, and a limited sliding bar 121 is symmetrically arranged along the through groove 122 on the inclined reflective plate 12. The movable reflective plate 14 is slidably connected to the limited sliding bar 121, and the movable reflective plate 14 is fixedly connected to the buckle limit plate 31, so that the buckle limit plate 31 slides in the horizontal direction and drives the high beam lamp panel 11 to move toward the center direction of the inclined reflective plate 12, and the movable reflective plate 14 will follow the movement of the buckle limit plate 31 to open the through groove 122, driving the light to irradiate the warning lamp cover 221, thereby lighting up the warning lamp cover 221 to warn pedestrians.

[0047] When the floodlighting environment is required, the adjusting protrusion 32 is toggled to slide along the slide groove 231, and the tooth plate 321 drives the coupling gear 33 to flip to drive the buckle limit plate 31 to move, thereby pushing the low beam lamp panel 10 and the high beam lamp panel 11 to move horizontally toward the high beam lamp panel 11, so that the low beam lamp panel 10 is close to the center line of the inclined reflector plate 12. At the same time, the contact point 101 will slide along the resistor strip 44, driving the high beam lamp panel 11 to reduce the brightness of the light, while the low beam lamp panel 10 increases the brightness of the light. , for road lighting, and when the pipeline under the road is excavated and repaired, the adjusting protrusion 32 is pushed to slide along the slide groove 231, pushing the low beam lamp board 10 and the high beam lamp board 11 to move horizontally toward the low beam lamp board 10, so that the high beam lamp board 11 approaches the center line of the inclined reflector 12, and at the same time, the contact point 101 will slide along the resistor bar 44, driving the high beam lamp board 11 to increase the brightness of the light, while the low beam lamp board 10 will reduce the brightness of the light, so as to illuminate the pipeline under the road.

[0048] In the process of increasing the high beam, when the brightness of the low beam lamp panel 10 is lower than that of the high beam lamp panel 11, the movable buckle limit plate 31 will drive the movable reflective plate 14 to open the through groove 122, so that the light shines on the warning lamp cover 221, and the warning lamp cover 221 will light up to warn pedestrians and vehicles. When the low beam lamp panel 10 and the high beam lamp panel 11 are lit, the heat flow generated will form an ascending heat flow, and the heat flow will merge and flow out along the outlet of the heat flow channel 210, and flow up along the dust partition plate 13, carrying away the dust. The vibration generated during road construction is damped by two sets of springs 43, driving the contact point 101 to always fit the resistor strip 44, and protecting the low beam lamp panel 10 and the high beam lamp panel 11.
