Description
Technical Field
[0001] The utility model belongs to the field of street lamps, in particular to an LED lighting street lamp with an automatic light adjustment function. Background Art
[0002] Street lights are lamps that provide lighting for roads and public places. They ensure people's safety and convenience at night or in low light conditions.
[0003] Street lights are mainly composed of lamp posts, lamp holders, control boxes and solar panels. Solar panels can receive sunlight, convert light energy into electrical energy and store it in the built-in battery of the street light. With this design, the lighting of the street light can be completely supplied by solar energy without consuming additional electricity.
[0004] However, on the one hand, since most solar panels are fixedly installed with their heads tilted upward and facing south, they can only receive maximum light when the sun is due south. When the sun is in other directions, the solar panels can also be illuminated, but the light is not directly opposite them. On the other hand, the fixed brightness of street lamps is not practical, because the sky gradually darkens. When the sky is still bright at the beginning, turning on the street lamps at maximum brightness is a waste of energy. Utility Model Content

[0007] Furthermore, when the ambient light is brighter, the photosensor outputs a low-level signal to the controller; the controller judges based on a preset threshold value, and if the light intensity is lower than the set brightness threshold, the controller will send a high-level signal to the drive circuit; the drive circuit receives the controller signal, increases the current or voltage supplied to the street lamp, and makes the street lamp brighter; when the ambient light becomes darker, the photosensor outputs a high-level signal to the controller; the controller judges again, and if the light intensity is higher than the set darkness threshold, the controller will send a low-level signal to the drive circuit; the drive circuit receives the controller signal, reduces the current or voltage supplied to the street lamp, and makes the street lamp darker.
[0008] Furthermore, the rotating mechanism includes a motor installed inside the installation box, and the output shaft of the motor and the outer peripheral side of the support rod are both fixedly sleeved with mutually meshing gears located inside the installation box.
[0009] Furthermore, a bearing may be installed in the through hole, and the support rod passes through the bearing.
[0010] Furthermore, a shielding mechanism is installed on the support rod, which is used to cover the through hole and rotates together with the support rod itself, so as to prevent rainwater from entering the installation box.
[0011] Furthermore, the shielding mechanism includes a round cover fixedly sleeved on the outer peripheral side of the support rod, and the round cover is a round basin structure with an open bottom end; at the same time, a ring groove cocentric with the through hole is opened at the top of the installation box, and the bottom end of the round cover is rotatably connected in the ring groove.
[0012] Furthermore, the bottom end of the round cover is constructed to form a rounded structure, and correspondingly, the bottom of the annular groove is adapted to the rounded structure to reduce friction during rotation.
[0013] Technical effects:
[0014] 1. In the utility model, the support rod can be driven to rotate under the action of the rotating mechanism, so that the support rod drives the solar panel to rotate, so that it can rotate with the sun and make the solar panel always face the sun.
[0015] 2. In the utility model, the shielding mechanism can cover the through hole without affecting the rotation of the support rod, thereby preventing rainwater from entering the installation box. If rainwater enters the installation box, water will accumulate therein, and the accumulated water will soak the motor and damage the motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
[0024] The LED street lamp with automatic light adjustment function provided in this embodiment is as follows: Figure 1 , Figure 2 and Figure 3 As shown, it includes a main component and an improved component, wherein:
[0025] The main component includes a lamp post 1 with a built-in controller and a battery. The top of the lamp post 1 is connected to a mounting box 2. The side of the mounting box 2 is connected to a lamp holder 3 and the top is connected to a support rod 4. The top of the support rod 4 is connected to a solar panel 5. The solar panel 5 receives light and converts light energy into electrical energy and stores it in a battery for powering the entire street lamp. In addition, a bearing seat 6 is also installed at the bottom end of the mounting box 2.
[0026] The improved assembly includes a through hole 7 with a diameter slightly larger than that of the support rod 4 opened at the top of the mounting box 2, the bottom end of the support rod 4 passes through the through hole 7 and is connected to the bearing seat 6, and a bearing can be installed in the through hole 7, and the bearing is passed through by the support rod 4 to enhance the stability of the support rod 4; in addition, on the one hand, a rotating mechanism 8 for driving the support rod 4 to rotate is provided inside the mounting box 2, such as Figure 4As shown, the rotating mechanism 8 includes a motor 801 installed inside the installation box 2. The output shaft of the motor 801 and the outer peripheral side of the support rod 4 are fixedly sleeved with mutually meshing gears 802 located inside the installation box 2. Driven by the motor 801, the support rod 4 can be driven to rotate through the two gears 802, so that the support rod 4 drives the solar panel 5 to rotate, so that it can rotate with the sun, so that the solar panel 5 always faces the sun; on the other hand, a photosensitive sensor is installed in the lamp head 3, and the photosensitive sensor is used to detect the light intensity and convert the light intensity into an electrical signal to transmit to the controller for controlling the brightness of the lamp head 3. The specific steps are as follows:
[0027] First, when the ambient light is bright, the photosensor outputs a low-level signal to the controller;
[0028] Second, the controller judges based on the preset threshold. If the light intensity is lower than the set brightness threshold, the controller will send a high-level signal to the drive circuit;
[0029] Third, the driving circuit receives the controller signal and increases the current or voltage supplied to the street lamp, making the street lamp brighter;
[0030] Fourth, when the ambient light becomes dim, the photosensor outputs a high-level signal to the controller;
[0031] Fifth, the controller judges again. If the light intensity is higher than the set darkness threshold, the controller will send a low-level signal to the driving circuit;
[0032] Sixth, the driving circuit receives the controller signal and reduces the current or voltage supplied to the street lamp, making the street lamp dim.
[0033] In addition, if Figure 4 and Figure 5 As shown, a shielding mechanism 9 is installed on the support rod 4 to cover the through hole 7 and rotate with the support rod 4 itself to prevent rainwater from entering the installation box 2. Because if rainwater enters the installation box 2, it will form water accumulation therein, and the accumulated water will soak the motor 801 and cause damage to the motor 801. Specifically, if Figure 5 As shown, the shielding mechanism 9 includes a round cover 901 fixedly sleeved on the outer peripheral side of the support rod 4, and the round cover 901 is a round basin structure with an open bottom end; at the same time, the top of the installation box 2 is provided with an annular groove 902 concentric with the through hole 7, and the bottom end of the round cover 901 is rotatably connected in the annular groove 902. In addition, the bottom end of the round cover 901 can be constructed to form a chamfered structure, and correspondingly, the bottom of the annular groove 902 is adapted to the chamfered structure to reduce the friction between the two when they rotate.
