Description

Technical Field

[0001] The utility model belongs to the technical field of lighting equipment, and particularly relates to a solar street lamp. Background Art

[0002] A solar street lamp is a lighting device that uses solar energy to generate electricity and store energy, and is used for lighting public areas such as roads, streets, sidewalks, and parking lots. During the day, the solar panel absorbs sunlight and converts it into electrical energy, while charging the battery; at night or when the light is insufficient, the street lamp converts the stored electrical energy into light energy through a controller to light up the LED lighting fixture to provide lighting services. Since solar street lamps do not require traditional power grid power supply, they can provide lighting in remote areas or places without power access, and are environmentally friendly, reducing carbon emissions; the main advantages of solar street lamps include energy conservation, environmental protection, utilization of renewable energy, low maintenance costs, and reliable lighting during power outages or emergencies. Therefore, they have been widely used in many places, especially in areas rich in solar resources.

[0003] However, existing solar street lamps usually use photovoltaic panels to convert sunlight into electrical energy, and then drive the lamps to emit light through a controller. However, since light is affected by various factors during propagation, such as atmospheric refractive index, air humidity, wind speed, etc., the refractive index of the light is reduced, which in turn affects the actual irradiation effect of the light. This will cause a large amount of loss of light energy during irradiation, reducing the service life and efficiency of solar street lamps;

[0004] Therefore, it is necessary to provide a solar street lamp that can improve its performance for use. Summary of the Utility Model

[0005] The embodiment of the utility model provides a solar street lamp to solve the problems in the prior art.

[0006] The embodiment of the utility model adopts the following technical solution: a solar street lamp, including a lamp body, on which several LED lamp beads are provided, a lens is provided outside the LED lamp beads, a rhombic crystal is provided on the surface of the lens, the rhombic crystal is arranged around the LED lamp beads, and several card lamp slots for clamping and installing the lamp body are provided on the side walls around the lamp body.

[0007] In a further technical solution, five card lamp slots are provided in the two length directions of the lamp body, the five card lamp slots are arranged at equal intervals, and two card lamp slots are provided in the two width directions of the lamp body.

[0008] In a further technical solution, several mounting holes are also provided on the lamp body.

[0009] The above at least one technical solution adopted by the embodiment of the utility model can achieve the following beneficial effects:

[0010] During the use of the lamp body of the present utility model, several LED lamp beads emit light, and the light passes through the lens and is reflected on the rhombic crystal of the reflective paper. Since the rhombic crystal is added to the lens, the rhombic crystal can reflect the light in multiple directions, and more refracted light is obtained, increasing the light utilization rate and reducing the light loss rate, resulting in a better lighting effect. In contrast, in the prior art where no rhombic crystal is added, existing ordinary lenses are all simple arc-shaped, and the light is reflected outward in a divergent manner. When the light is refracted and reflected at 180 degrees, it cannot be re-emitted, resulting in a poor lighting effect of the light. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0019] The following will, with reference to the drawings, detail the technical solutions provided by the embodiments of the present utility model.

[0020] Refer to Figures 1 to 4As shown in the figure, an embodiment of the present utility model provides a solar street lamp, including a lamp body 1, on which a number of LED lamp beads 2 are provided. A lens is provided outside the LED lamp beads 2, and a rhombic crystal 3 is provided on the surface of the lens. The rhombic crystal 3 is arranged around the LED lamp beads 2. A number of card lamp grooves 4 for clamping and installing the lamp body 1 are provided on the side walls around the lamp body 1.

[0021] During the use of the lamp body 1, a number of LED lamp beads 2 emit light, and the light passes through the lens and is reflected on the rhombic crystal 3. Since the rhombic crystal 3 is added to the lens, the rhombic crystal 3 can reflect the light in multiple directions, and more refracted light is obtained, increasing the light utilization rate and reducing the light loss rate, resulting in a better lighting effect. Compared with the prior art where the rhombic crystal 3 is not added, existing ordinary lenses are all simple arc-shaped, and the light is reflected outward in a divergent manner. When the light is refracted and reflected at 180 degrees, it cannot be re-emitted, resulting in a poor lighting effect of the light.

[0022] The multiple planes of the rhombic crystal 3 can reflect light in different directions, thus realizing flexible change of the light path. This is very useful in the design of optical systems and can guide light to specific positions or areas according to needs.

[0023] For the rhombic crystal 3 material with a specific refractive index, when light is incident at a certain angle, total internal reflection can be achieved inside the rhombic crystal 3. The total internal reflection phenomenon can efficiently reflect light inside the rhombic crystal 3 with almost no energy loss.

[0024] The rhombic crystal 3 has a specific geometric shape, and the angles and planes on its surface can be precisely designed and processed. This enables light to be reflected at a predetermined angle on the surface of the rhombic crystal 3, reducing energy loss and scattering during the reflection process.

[0025] It should be noted that the LED lamp beads 2 in this application are electrically connected to the solar panel and are used with a safe voltage of 36V, and only the voltage using solar energy can be utilized.

[0026] Specifically, five card lamp grooves 4 are provided in the two length directions of the lamp body 1, and the five card lamp grooves 4 are arranged at equal intervals. Two card lamp grooves 4 are provided in the two width directions of the lamp body 1. When the lamp body 1 is installed, through the card lamp grooves 4 in the length direction and the card lamp grooves 4 in the width direction, the connection between the lamp body 1 and the lamp box is more firmly clamped, increasing the wind resistance of the lamp body 1 and increasing the friction force, making the fixing effect of the lamp body 1 better.

[0027] Specifically, a number of mounting holes 5 are also provided on the lamp body 1. During the installation of the lamp body 1, the lamp body 1 can be installed on the lamp box through screws using the number of mounting holes 5, making the installation of the lamp body 1 more firm.

[0028] The above are only embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
