Description

Technical Field

[0001] The present invention relates to the field of construction lighting, in particular to a temporary lighting device for construction. Background Art

[0002] In the field of industrial plant lighting, traditional lighting solutions have many problems that need to be solved.

[0003] Currently, the divergence angle of commonly used lamps reaches 120°-140°. This wide range of light divergence causes the ambient illumination of the factory building to seriously exceed the standard, often exceeding 10lx, resulting in severe light pollution and causing significant disruption to the lives of surrounding residents. Furthermore, the strong, undirected light can easily cause glare, dazzling construction workers and significantly increasing safety risks during construction.

[0004] From the perspective of energy consumption, traditional fixed-power lamps cannot be dynamically adjusted according to the ambient light intensity, and they still operate at full power during the day or when there is sufficient light, resulting in a large amount of energy waste.

[0005] In addition, the installation method of lamps is rigid, and their height and angle are fixed and cannot be adjusted, which makes it difficult to meet the personalized lighting needs of complex and changing construction scenarios.

[0006] Existing control technologies for addressing this light pollution problem also have limitations. For example, while hoods or baffles can block light to a certain extent, they cannot precisely control the beam direction and can reduce lighting efficiency. While using low-color-temperature light sources can reduce the proportion of blue light, this comes at the expense of brightness, making it impossible to meet the lighting intensity requirements of actual construction. Summary of the Invention

[0007] Based on this, it is necessary to provide a temporary lighting device for construction to address the above technical problems. It can accurately control the direction of the light beam, will not cause light pollution, will not interfere with the lives of surrounding residents, and the strong light after directionality will not cause glare problems, thereby avoiding dazzling construction workers and making the construction process safer.

DETAILED DESCRIPTION

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] The following combination Figures 1 to 6 The present invention describes a temporary lighting device for construction.

[0035] like Figure 1 and Figure 2As shown, in one embodiment, a temporary lighting device for construction includes a mounting frame 100, an adjustment seat 200, a plurality of limiting rods 300, a mask 400 and a transparent cover 500; a mounting cavity 141 is provided inside the mounting frame 100, and a lamp with adjustable illuminance is installed in the mounting cavity 141; the adjustment seat 200 is installed at the bottom end of the mounting frame 100 and can move along the central axis of the mounting frame 100; a plurality of limiting rods 300 are arranged in a circular array on the periphery of the mounting frame 100, one end of the limiting rod 300 is connected to the top of the mounting frame 100, and the other end is connected to the outer ring of the adjustment seat 200, the middle part of the limiting rod 300 is bent in a direction away from the mounting frame 100, and the limiting rod can be deformed when subjected to force; the mask 400 is covered on the plurality of limiting rods 300, and the mask 400 is elastic; the transparent cover 500 is installed on the inner ring of the adjustment seat 200, and the interior of the transparent cover 500 can be stuck with the lamp.

[0036] The above-mentioned temporary lighting device for construction, when in use, installs the lamp into the installation cavity 141 through the bottom of the mounting frame 100, and then installs the transparent cover 500 on the inner circle of the adjustment seat 200. According to actual use needs, required items, such as insect repellent items, etc., can be placed in the transparent cover 500. Then the mounting frame 100 is fixed to the pre-set lighting location. According to current needs, multiple limit rods 300 can be adjusted to make the bottom end of the limit rod 300 move longitudinally, thereby changing the coverage range of the mask 400 and adjusting the lighting range of the lamp. By adjusting the limit rod 300, the direction of the light beam can be accurately controlled, without forming light pollution or interfering with the lives of surrounding residents, and the strong light after directionality will not cause glare problems, thereby avoiding dazzling construction workers and making the construction process safer.

[0037] It should be noted that, in this embodiment, the transparent cover 500 and the mounting bracket 100 have the same degree of transparency, and both can allow the light to reach the target range with almost no attenuation, while the mask 400 is preferably made of white transparent material. Although it can also transmit light, it will cause a certain weakening of the light. This setting ensures that the light of the lamp will not be wasted and will not cause light pollution to the surrounding ring.

[0038] like Figure 3 As shown, in one embodiment, the mounting frame 100 includes a fixed tube 110 and a first annular plate 120; a plurality of through-holes 111 are provided on the surface of the fixed tube 110, and the plurality of through-holes 111 are arranged in an annular array, and the through-holes 111 are located in the lower half of the fixed tube 110; the first annular plate 120 is sleeved on the top end of the fixed tube 110, and a plurality of first long holes 121 are provided on the first annular plate 120 in an annular array.

[0039] Specifically, the through-opening 111 is arranged vertically so that other components can move in the vertical direction in the through-opening 111. A cover plate 130 is provided at the top of the fixed tube 110, and a mounting seat 140 is provided at the bottom of the cover plate 130. A mounting cavity 141 is formed in the mounting seat 140. A power pole 150 is provided on the top surface of the cover plate 130. The power pole 150 forms an electrical connection with the mounting cavity 141 and is used to connect the positive and negative poles of the lamp installed in the mounting cavity 141 to an external power supply device.

[0040] Among them, positive and negative poles are set in the mounting base 140, and the power pole 150 on the top surface of the cover 130 is connected to the positive and negative poles of the mounting base 140. After the mounting part is fixed, the two power poles 150 are respectively connected to the positive and negative poles of the power supply equipment. When the lamp is installed in the mounting cavity 141, the positive and negative poles of the lamp are connected to the positive and negative poles of the power supply equipment, so that lighting can be achieved. The control of the lamp can be set between the power supply equipment and the positive and negative poles of the lamp.

[0041] Since this embodiment only improves the structure of the lighting device and does not involve improvements to the lamp body, power supply equipment, adjustment method and line connection, no specific description is given in this embodiment.

[0042] like Figure 4 and Figure 5 As shown, in one embodiment, the adjustment seat 200 includes a second annular plate 210 and an annular folding plate 220; the second annular plate 210 is movably mounted on the outer ring of the fixed tube 110, and a plurality of second long holes 211 are opened in an annular array on the second annular plate 210, and the annular folding plate 220 is movably clamped in the inner ring of the fixed tube 110, and the second annular plate 210 and the annular folding plate 220 are connected by a plurality of connecting rods 230, and the plurality of connecting rods 230 are respectively clamped in the plurality of through openings 111.

[0043] Specifically, the first long holes 121 and the second long holes 211 are configured as non-circular holes, and the length direction or the width direction coincides with the radius of the fixing tube 110 . The plurality of first long holes 121 are respectively opposite to the plurality of second long holes 211 in the vertical direction.

[0044] When the two ends of the limiting rod 300 are respectively installed in the first long hole 121 and the second long hole 211, no matter how the limiting rod 300 is adjusted, it will always only move within the axial section range of the fixed tube 110, affected by the length or width direction settings of the first long hole 121 and the second long hole 211, ensuring that multiple limiting rods 300 will not affect each other.

[0045] In one embodiment, the limiting rod 300 includes a bent rod 310 and a straight rod 320; the two straight rods 320 are respectively inserted into the corresponding first long hole 121 and second long hole 211 above and below, and the two ends of the bent rod 310 are respectively connected to the two straight rods 320. When subjected to force, the bent rod 310 is compressed and bent or stretched to become straight by the two straight rods 320.

[0046] Specifically, the straight rod 320 portion does not bend, and the straight rod 320 portion is installed in the first long hole 121 or the second long hole 211, and the bent rod 310 portion is used to bear force, thereby generating deformation, bending or being straightened.

[0047] In one embodiment, the mask 400 is covered on the outside of multiple straight rods 320 and curved rods 310. When the bending state of the curved rod 310 changes, or the distance between the two straight rods 320 opposite to each other changes, the middle area or the upper and lower ends of the mask 400 will change with the changes of the curved rod 310 or the straight rod 320, and will always remain covered on the periphery of the limiting rod 300.

[0048] Specifically, the mask 400 can be formed by performing longitudinal and transverse folding processing on a translucent elastic material and then being mounted on the plurality of limiting rods 300 , or can be directly mounted on the plurality of limiting rods 300 .

[0049] The wrinkled mask 400 can provide more redundancy for the deformation of the limiting rod 300 and will not be torn due to the bending deformation of the bending rod 310 .

[0050] In one embodiment, the annular folding plate 220 includes a folding plate 221 and an annular plate 222; the folding plate 221 is arranged in an annular structure, the outer ring of the folding plate 221 is movably fitted with the inner surface of the fixed tube 110, and the inner ring of the folding plate 221 extends toward the central axis of the fixed tube 110 and is connected to the annular plate 222, and the inner surface of the annular plate 222 is provided with an annular groove 2221.

[0051] Specifically, a plurality of driving members are arranged in an annular array on the periphery of the fixed tube 110. The second annular plate 210 is elastic and can be deformed under force. The driving end of the driving member abuts against a position on the second annular plate 210 that is staggered from the connecting rod 230, and is used to push the position where the second annular plate 210 is connected to the straight rod 320 to deform, thereby changing the position and state of the straight rod 320 and the bent rod 310.

[0052] Among them, the second annular plate 210 can be set as a plate made of elastic material. Since the outer circle of the annular folding plate 220 is connected to multiple connecting rods 230, and each connecting rod 230 is located between two adjacent straight rods 320, when the driving member pushes the part of the second annular plate 210 connected to the straight rod 320, the annular plate 222 can be deformed, thereby further adjusting the range of the mask 400 according to implementation needs.

[0053] like Figure 6 As shown, in one embodiment, the transparent cover 500 includes a mounting tube 510 and a hemispherical shell 520. The outer ring of the mounting tube 510 is provided with a snap ring 530, and the snap ring 530 is used to be clamped in the annular groove 2221. The flat end of the hemispherical shell 520 is connected to the bottom end of the mounting tube 510, and the inner diameter of the mounting tube 510 is larger than the outer diameter of the lamp.

[0054] Specifically, the transparent cover 500 is arranged so that when the two upper and lower opposite straight rods 320 approach each other to a certain extent, the end of the lamp will be stuck in the transparent cover 500, thereby sealing the bottom of the lamp. In addition, if some special items, such as insect repellent, are placed in the transparent cover 500 or on the annular folding plate 220, it can prevent mosquitoes from approaching and affecting the lamp.

[0055] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
