Description

Technical Field

[0001] This utility model relates to the field of solar lighting equipment technology, specifically to a solar street light with adjustable illumination position. Background Technology

[0002] Traditional integrated solar streetlights typically mount the LED light source and lens fixed inside the south-facing lamp body to maximize sunlight reception efficiency. However, this design has a fundamental flaw: because the relative position of the light source and lens is not adjustable, the direction and range of the illumination beam are permanently fixed. When actual lighting needs change (e.g., illuminating the sidewalk instead of the center of the road), or when the installation location is limited by the surrounding environment, existing streetlights cannot dynamically adjust the light path, resulting in energy waste or blind spots.

[0003] Existing technologies have attempted to change the direction of illumination by rotating the lamp head or adjusting the lens angle, but these solutions expose moving parts, compromise the lamp's seal, and allow rainwater and dust to infiltrate, shortening its lifespan. Furthermore, mechanical rotating structures require additional space, contradicting the trend towards miniaturization and integration in solar streetlights. Therefore, there is an urgent need for a solar streetlight technology that can achieve precise adjustment of the illumination position without compromising the seal and compact structure. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a solar street light with adjustable illumination position, which solves the problem that solar street lights in traditional technology cannot change the illumination direction.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a solar street light with adjustable illumination position, including a light source assembly, a lens matrix and a moving device;

[0007] The lens matrix is ​​configured to refract light emitted from the light source assembly to form an illumination beam; the moving device is operably connected to the light source assembly and configured to move the light source assembly relative to the lens matrix, thereby adjusting the illumination position of the illumination beam by changing the relative position between the light source assembly and the lens matrix.

[0008] The moving device is configured to move the light source assembly in a direction perpendicular to the optical axis direction of an individual lens in the lens matrix.

[0009] In some embodiments, the light source assembly includes a substrate and a plurality of LED units, the plurality of LED units being arranged on the substrate, and the lens matrix including a number of lens units equal to the number of LED units, the arrangement positions of the lens units corresponding one-to-one with the LED units.

[0010] In some embodiments, the moving device includes a motor, a transmission screw, and a movable bolt, and one end of the base plate is connected to a fixed base;

[0011] The motor is connected to the movable bolt via the transmission screw. The fixed seat is provided with an internal thread that is compatible with the movable bolt. The motor drives the fixed seat to move back and forth in a straight line along the axis of the movable bolt by reversing forward and reverse rotation.

[0012] In some embodiments, a first housing and a second housing are further included, the first housing and the second housing being fixedly fitted together vertically, and the light source assembly, lens matrix and moving device are integrated inside the housing;

[0013] The first housing is provided with a sealing groove, and a sealing ring is embedded in the sealing groove. The second housing is provided with a sealing rib corresponding to the position of the sealing groove. The sealing groove surrounds the radial outer ring of the light source assembly, lens matrix and moving device.

[0014] In some embodiments, the first housing or the second housing is provided with a limiting protrusion, which is used to limit the substrate in the vertical direction after the substrate is installed in place.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] This application uses a moving device to drive the light source assembly to move vertically relative to the lens matrix, thereby changing the incident angle of the light and dynamically deflecting the direction of the illumination beam by utilizing the refraction effect of the lens, thus achieving flexible adjustment of the illumination position.

[0017] When the light source assembly moves perpendicular to the lens optical axis, the light emitted by each LED unit is incident on the corresponding lens unit at an asymmetrical angle, and is directionally deflected after refraction. This design avoids complex rotating mechanisms, and only requires a small linear displacement to achieve a significant change in the illumination position, resulting in faster optical path adjustment response and lower energy consumption.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] Reference Figures 1 to 6 This embodiment proposes a solar street light with adjustable illumination position, including a light source assembly 10, a lens matrix 20 and a moving device 30;

[0031] The lens matrix 20 is configured to refract light emitted from the light source assembly 10 to form an illumination beam; the moving device 30 is operably connected to the light source assembly 10 and configured to move the light source assembly 10 relative to the lens matrix 20, thereby adjusting the illumination position of the illumination beam by changing the relative position between the light source assembly 10 and the lens matrix 20; the moving device 30 is configured to move the light source assembly 10 in a direction perpendicular to the optical axis direction of a single lens in the lens matrix 20.

[0032] It should be noted that, in order to dynamically adjust the illumination position without changing the orientation of the lamp, the light source assembly 10 and the lens matrix 20 are set up accordingly in this embodiment. The light emitted by the light source assembly 10 is refracted by the lens matrix 20 to form an illumination beam. The moving device 30 drives the light source assembly 10 to translate relative to the lens matrix 20, changing the angle at which the light is incident on the lens. The change in the incident angle causes the direction of the refracted beam to shift, thereby realizing stepless adjustment of the illumination position.

[0033] Furthermore, since the choice of the direction of light source movement directly affects the adjustment efficiency and optical path stability, preferably, in this embodiment, the light source assembly 10 is limited to moving in a direction perpendicular to the optical axis of a single lens (not along the optical axis). By controlling the vertical movement of the light source assembly 10, the rate of change of the incident angle of light can be maximized, and a small displacement can produce a significant beam deflection (in contrast, moving along the optical axis requires a larger vertical stroke), and the light source is prevented from blocking the outgoing light path.

[0034] Combination Figure 5In one embodiment, the light source assembly 10 includes a substrate 11 and a plurality of LED units 12, the plurality of LED units 12 being arranged on the substrate 11, and the lens matrix 20 including a number of lens units 21 equal to the number of LED units 12, the arrangement positions of the lens units 21 corresponding one-to-one with the LED units 12.

[0035] To ensure beam consistency in a multi-source system, LED units 12 and lens units 21 are arranged in the same number and position to form discrete optical channels. Each LED-lens pair independently completes the optical path deflection, eliminating interference from multiple sources and ensuring the stability of the irradiated area shape.

[0036] Combination Figure 3 and Figure 5 In one embodiment, the mobile device 30 includes a motor 31, a transmission screw 32 and a movable bolt 33, and a fixed base 13 is connected to one end of the base plate 11;

[0037] The motor 31 is connected to the movable bolt 33 via the transmission screw 32. The fixed seat 13 is provided with an internal thread that is compatible with the movable bolt 33. The motor 31 drives the fixed seat 13 to move back and forth in a straight line along the axis of the movable bolt 33 by forward and reverse rotation.

[0038] To achieve precise micro-displacement of the light source assembly 10, the motor 31 drives the transmission screw 32 to rotate, which in turn drives the movable bolt 33 to rotate axially. The internal thread of the fixed seat 13 engages with the movable bolt 33, converting the rotational motion into linear displacement of the substrate 11. By controlling the forward and reverse rotation of the motor 31, the fixed seat 13 can be driven to move forward or backward. Moreover, the transmission ratio is controllable, the displacement accuracy is high, and the micro-operation requirements of optical path adjustment are met.

[0039] Combination Figure 6 In one embodiment, it also includes a first housing 41 and a second housing 42, with the first housing 41 and the second housing 42 fixedly fitted together vertically, and integrating the light source assembly 10, the lens matrix 20 and the moving device 30 inside the housing;

[0040] The first housing 41 is provided with a sealing groove 43, and a sealing ring 44 is embedded in the sealing groove 43. The second housing 42 is provided with a sealing rib 45 corresponding to the position of the sealing groove 43. The sealing groove 43 surrounds the radial outer ring of the light source assembly 10, the lens matrix 20 and the moving device 30.

[0041] To ensure compatibility between the moving parts and the sealing performance, a sealing ring 44 is embedded in the sealing groove 43 of the first housing 41, and the sealing rib 45 of the second housing 42 presses the sealing ring 44 during assembly to form a closed-loop seal around the internal components. Even when the substrate 11 moves, the elastic deformation of the sealing ring 44 maintains the sealing interface, achieving an IP67 protection level.

[0042] Additionally, a photovoltaic panel is provided on the upper part of the first housing 41, and a lens matrix 20 is fixed on the lower surface of the second housing 42.

[0043] Preferably, due to the possible tilting or vibration that may occur during the movement of the substrate 11, a limiting protrusion is provided in the first housing 41 or the second housing 42. The limiting protrusion is used to limit the substrate 11 in the vertical direction after it is installed in place. By providing the limiting protrusion in the housing, when the substrate 11 is installed in place, the protrusion constrains its vertical degree of freedom, eliminates unexpected displacement, and ensures that the light source assembly 10 and the lens matrix 20 always maintain a parallel relative position.

[0044] In summary, compared with the prior art, the above embodiments have at least the following technical advantages:

[0045] When the light source assembly 10 moves perpendicular to the optical axis of the lens, the light emitted by each LED unit 12 is incident on the corresponding lens unit 21 at an asymmetrical angle, and is directionally deflected after refraction. This design avoids complex rotating mechanisms, and only requires a small linear displacement to achieve a significant change in the illumination position, resulting in faster optical path adjustment response and lower energy consumption.

[0046] The planar arrangement and vertical movement of the light source assembly 10 and lens matrix 20 allow all optical elements to be completely enclosed within the housing. The pressing structure of the sealing groove 43 and the sealing rib 45 ensures that IP65 or higher protection is maintained during movement, solving the sealing failure problem of traditional adjustable lamps.

[0047] In the lens matrix 20, each lens unit 21 independently corresponds to an LED unit 12, forming discrete optical channels. When the light source assembly 10 moves as a whole, the light deflection angle of each channel is highly consistent, avoiding beam distortion and ensuring clear boundaries and uniform brightness of the irradiated area.

[0048] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
