[0002] Street lights refer to lamps that provide lighting for roads. They are also luminous lighting systems on streets and public squares. They generally refer to lamps within the range of road lighting in traffic lighting. Street lights are widely used in various places that need lighting. They are usually turned on at night or dark and turned off after dawn. The basic function of street lights is lighting, and their additional functions can be works of art, landmarks, road signs, telephone booths, message boards, mailboxes, gathering places, advertising light boxes, etc.

[0003] However, existing street lamps have the following defects: in bad weather and environment, the lighting effect of street lamps will decrease, it is difficult to provide sufficient lighting brightness for the road, and the sight observation of pedestrians and vehicles will be affected. Summary of the invention

[0004] One object of the present application is to provide a brightness-adaptive LED street lamp that can change the lighting brightness mode according to the external environment.

[0005] To achieve the above objectives, the technical solution adopted in the present application is: a brightness adaptive LED street lamp, comprising a lamp post and a lamp body, the lamp body being installed on the lamp post, a lighting cavity being opened on the lamp body, a light source being arranged in the lighting cavity, a light-transmitting portion being arranged on the lamp body, the light-transmitting portion being suitable for shielding the lighting cavity and the light source, the light-transmitting portion comprising a soft light layer and at least one lighting layer, the lighting layer being fixedly arranged, the soft light layer being suitable for unfolding along the lighting layer and shielding the lighting cavity and the light source, and the soft light layer being suitable for being folded toward one side of the lighting cavity along the lighting layer.

[0006] In some embodiments, a reeling device is provided on the lamp body, and the reeling device includes a reel and a reeling drive, the reel is connected to the soft light layer, and the reeling drive is suitable for driving the reel to rotate and reel in or unfold the soft light layer.

[0007] In some embodiments, a supporting portion is disposed on the soft light layer, and when the soft light layer is unfolded, the supporting portion is suitable for allowing the soft light layer to be smoothly unfolded along the lighting layer.

[0008] In some embodiments, the support portion is arranged along the edge of the soft light layer, and an embedding groove is provided around the lighting cavity. The support portion is suitable for being hidden in the embedding groove, and the support portion is suitable for moving along the embedding groove.

[0009] In some embodiments, a first sensor is disposed on the lamp body, and the first sensor is suitable for sensing temperature and / or rainfall, and sending a first control signal to the retracting drive.

[0010] In some embodiments, the first sensor is arranged on the upper part of the lamp body.

DETAILED DESCRIPTION

[0024] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0027] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0028] The present application is further described below with reference to the accompanying drawings:

[0029] like Figures 1 to 5As shown, the present application provides a brightness-adaptive LED street lamp, including a lamp post 1 and a lamp body 2, the lamp body 2 is installed on the lamp post 1, a lighting cavity 21 is opened on the lamp body 2, a light source 22 is arranged in the lighting cavity 21, a light-transmitting portion 23 is arranged on the lamp body 2, the light-transmitting portion 23 is suitable for shielding the lighting cavity 21 and the light source 22, the light-transmitting portion 23 can be closedly connected with the lighting cavity 21 on all sides, the light-transmitting portion 23 is equivalent to the lampshade on the traditional lamp body 2, which is used to isolate the external environment and protect the light source 22.

[0030] The light-transmitting portion 23 includes a soft light layer 231 and at least one lighting layer 232 . The lighting layer 232 is fixedly arranged. The soft light layer 231 is suitable for being unfolded along the lighting layer 232 and covering the lighting cavity 21 and the light source 22 . The soft light layer 231 is suitable for being folded toward one side of the lighting cavity 21 along the lighting layer 232 .

[0031] In some embodiments, the lighting layer 232 is preferably made of a transparent material to allow light to be emitted to the external environment with the highest efficiency, thereby improving the lighting brightness.

[0032] In some embodiments, the soft light layer 231 may be made of a translucent material with a slightly lower light transmittance than the lighting layer 232 , so that light can be emitted to the external environment more softly and evenly through diffuse reflection.

[0033] In some embodiments, the soft light layer 231 can be made of a flexible material such as translucent silicone, which can ensure both flatness and fit when unfolded and light transmittance.

[0034] By arranging the soft light layer 231 as an active structure, the switching of the street lamp mode can be achieved. When the soft light layer 231 is unfolded, it can avoid the light being too glaring and improve the comfort of lighting. When the soft light layer 231 is folded, it can increase the light emission rate, thereby improving the brightness of the lighting. Since the mode switching is achieved in the form of a physical structure, it will not cause additional load on the light source 22, reducing the impact on the stability and life of the light source 22.

[0035] A reeling device 24 is provided on the lamp body 2 , and the reeling device 24 includes a reel 241 and a reeling driver 242 . The reel 241 is connected to the soft light layer 231 , and the reeling driver 242 is suitable for driving the reel 241 to rotate and retract or unfold the soft light layer 231 .

[0036] like Figures 2 to 4 In the embodiment shown, the reel 241 and the reel-in drive 242 can be arranged in the lamp body 2 on one side of the lighting cavity 21 to make full use of the internal space of the lamp body 2. Since the soft light layer 231 is a thin structure, only a small space is required, and the reel 241 and the reel-in drive 242 with a small volume can control the folding and unfolding of the soft light layer 231. The structure is less difficult to implement and can be easily arranged.

[0037] In some embodiments, the reel-up drive 242 may be connected to the end of the reel 241 via gears for transmission.

[0038] like Figures 3 to 4 In the illustrated embodiment, a support portion 2311 is provided on the soft light layer 231. When the soft light layer 231 is unfolded, the support portion 2311 is suitable for making the soft light layer 231 unfold smoothly along the lighting layer 232. The main function of the support portion 2311 is to maintain the flatness of the soft light layer 231 to prevent the soft light layer 231 from having large wrinkles or even overlapping during the process of folding and unfolding, which would affect the normal function of the soft light layer 231.

[0039] like Figure 2 In the illustrated embodiment, the support portion 2311 is arranged along the edge of the soft light layer 231 , and can play a role similar to a supporting frame, thereby shaping the overall structure of the soft light layer 231 and preventing the soft light layer 231 from moving around, wrinkling or folding.

[0040] like Figure 2 In the illustrated embodiment, the lighting cavity 21 is surrounded by fitting grooves 211, the support portion 2311 is suitable for being hidden in the fitting grooves 211, and the support portion 2311 is suitable for moving along the fitting grooves 211. The fitting grooves 211 can prevent the support portion 2311 from being exposed in the lighting cavity 21, thereby reducing obstruction to the light emitted by the light source 22 and making the lighting effect of the lamp body 2 more complete and integrated.

[0041] In some embodiments, the support portion 2311 may be made of elastic metal, which can provide sufficient supporting force and can also be rolled up by the reel 241 .

[0042] It is worth noting that the use of elastic metal for the support portion 2311 is a preferred embodiment. In actual use, it is only necessary to ensure that the material of the support portion 2311 can be rolled up by the reel 241 and can restore its original state using its own properties when unfolded (i.e., help the soft light layer 231 to restore its flat state).

[0043] In some embodiments, a first sensor 25 is disposed on the lamp body 2. The first sensor 25 is suitable for sensing temperature and / or rainfall and sending a first control signal to the reeling driver 242. The first sensor 25 can sense and infer the external environment through temperature and rainfall.

[0044] In some embodiments, the second sensor 11 may be a temperature sensor or a rain sensor or a combination of the two.

[0045] like Figure 1 In the illustrated embodiment, the first sensor 25 is arranged on the upper part of the lamp body 2 to ensure that the temperature and rain data can be accurately received and sensed, thereby issuing a first control signal.

[0046] In some embodiments, a second sensor 11 is provided on the lamp post 1. The second sensor 11 is suitable for sensing the brightness of light and sending a second control signal to the retracting drive 242. When rain, fog, and dust appear in the surrounding environment, and the brightness of the street lamp is seriously affected, the second sensor 11 can sense and send the second control signal in time.

[0047] In some embodiments, the second sensor 11 may be a light sensor.

[0048] like Figure 1 In the illustrated embodiment, the second sensor 11 is arranged on the side of the lamp post 1 close to the lamp body 2 to ensure that the brightness of the light emitted by the lamp body 2 can be received and sensed more accurately, thereby issuing a first control signal.

[0049] The retracting driver 242 can combine the received first control signal and the second control signal and actively determine whether to start operation, thereby realizing the sensing environment and mode switching of the street lamp.

[0050] like Figures 2 to 3 In the illustrated embodiment, the number of the lighting layers 232 is multiple, at least one lighting layer 232 is located outside the soft light layer 231 , and the outermost lighting layer 232 can protect the soft light layer 231 .

[0051] like Figure 3 In the illustrated embodiment, there are two lighting layers 232 , and the soft light layer 231 is suitable for being spread out between the two lighting layers 232 . The two lighting layers 232 can guide the movement of the soft light layer 231 in the form of a sandwich to prevent the soft light layer 231 from moving randomly.

[0052] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
