Description

Technical Field

[0001] The utility model relates to the technical field of flagpole lights, and more specifically, it relates to a solar flagpole light. Background Art

[0002] At present, the mainstream solar flagpole lights on the market are used at the top of the flagpole. They adopt photovoltaic technology and use LEDs as the basic light source to illuminate the flag. In previous designs, most of the light sources were in the form of direct emission of LEDs. Since the light-emitting angle of the LED package is 120 degrees, the entire light source is in the form of diffuse reflection, and only about 40% of the light hits the upper end of the flag, resulting in waste of the light source.

[0003] At the same time, all the flagpole lights on the market have a one-way downward lighting optical design. As shown in the flagpole lights disclosed in the patent documents with the publication numbers of CN204986832U or CN204962568U, there is no two-way up and down lighting design, that is, the existing flagpole lights cannot illuminate the decorative parts installed at the top of the lamp post. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a solar flagpole light, which can illuminate the flag to the greatest extent with the least energy consumption under limited resources and costs, or bring a better visual experience to users at the same time.

[0005] The above technical purpose of the present utility model is achieved through the following technical solutions:

[0006] A solar flagpole light, comprising: a lamp housing which is frustum-shaped and has an installation cavity, a plurality of first conical reflector cups are arranged on the side wall of the lamp housing, a first LED lamp bead is arranged at the narrow-caliber end of the first conical reflector cup, and a first optical lens for converging the light emitted by the first LED lamp bead onto the flag is arranged at the wide-caliber end of the first conical reflector cup; a battery pack and a control board are arranged in the installation cavity of the lamp housing; at least one solar panel is arranged on the top of the lamp housing; the solar panel, the battery pack and the first LED lamp bead are all electrically connected to the control board; an installation hole for fixing the lamp housing on the flagpole is opened on the lamp housing.

[0007] Optionally, a ring-shaped light belt for illuminating the decorative parts installed at the top of the flagpole is arranged on the top of the lamp housing, and the ring-shaped light belt is electrically connected to the control board.

[0008] Optionally, a plurality of second LED lamp beads are equidistantly arranged on the ring-shaped light belt.

[0009] Optionally, both the first LED lamp bead and the second LED lamp bead are RGB lamp beads capable of emitting several colors.

[0010] Optionally, a daylight sensor for controlling the first LED lamp bead to turn on or off is arranged on the lamp housing, and the daylight sensor is electrically connected to the control board.

[0011] Optionally, a plurality of second conical reflective cups are arranged at the bottom of the lamp housing, a third LED lamp bead is arranged at the thin-diameter end of the second conical reflective cup, and a second optical lens for converging the light emitted by the third LED lamp bead onto the flag is arranged at the thick-diameter end of the second conical reflective cup; the third LED lamp bead is electrically connected to the control board.

[0012] In summary, the utility model has the following beneficial effects: 1) The first LED lamp bead of the diffuse light source is re-distributed, and the light emitted by the first LED lamp bead is converged on the flag in a more concentrated form by using the first optical lens in cooperation with the first conical reflective cup, while making the irradiation distance farther. The principle is: the first optical lens reduces the divergence of light in invalid space, so that more than 70% of the overall light is concentrated on the flag. Under the condition of the same luminous flux, it can obtain higher illumination and range than the flagpole lamps with the same parameters on the market, so that the final lighting effect is greatly improved. 2) A ring light belt is installed on the top of the lamp housing, so that the flagpole lamp can achieve the effect of one lamp with two uses. It can not only illuminate the objects under the lamp housing, but also optically beautify the decorative parts above the lamp housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following describes the present utility model in detail with reference to the accompanying drawings and embodiments.

[0023] The present utility model provides a solar flagpole lamp, such as Figures 1-5As shown, it includes: a truncated cone-shaped lamp housing 1 with an installation cavity, a plurality of first conical reflective cups 2 are arranged on the side wall of the lamp housing 1, a first LED lamp bead 3 is arranged at the thin-diameter end of the first conical reflective cup 2, and a first optical lens 4 for converging the light emitted by the first LED lamp bead 3 onto the flag 92 is arranged at the thick-diameter end of the first conical reflective cup 2; a battery pack and a control board are arranged in the installation cavity of the lamp housing 1; at least one solar power generation panel 5 is arranged on the top of the lamp housing 1; the solar power generation panel 5, the battery pack and the first LED lamp bead 3 are all electrically connected to the control board; and a mounting hole 11 for fixing the lamp housing 1 on the flagpole 9 is opened on the lamp housing 1.

[0024] Specifically, the lamp housing 1 is a hollow shell, and the hollow space forms an installation cavity (not shown in the figure) for installing a battery pack, a control panel, and a first conical reflector cup 2. Among them, the installation cavity, the battery pack, and the control panel are not shown in the figure. The battery pack is a conventional battery module composed of a number of lithium batteries or lead-acid batteries connected in parallel or in series. This is a prior art and will not be described in detail here; the control panel is a circuit board composed of electronic components such as a single-chip microcomputer, a relay, and a wireless communication module. This is a prior art and will not be described in detail here. The lamp housing 1 is surrounded by a top plane, a bottom plane, and a side wall arc surface. An inspection panel 13 and a button switch 14 are installed on the bottom plane. The inspection panel 13 facilitates the removal of the battery pack and the control panel from the installation cavity for inspection; the button switch 14 is used to control the conduction or disconnection of the battery pack and the control panel. Three fan-shaped solar panels 5 are installed on the top plane of the lamp housing 1 by adhesive and screws in an existing fixing method, but the number and shape of the solar panels 5 can be designed according to actual needs and should not be limited to this. The mounting hole 11 is located at the center of the lamp housing 1 and penetrates the mounting cavity for the flagpole 9 to pass through. A plurality of first conical reflective cups 2 are mounted on the inner side of the arcuate surface of the side wall of the lamp housing 1 by screw fixing, snap fixing, adhesive fixing, or other existing methods. The plurality of first conical reflective cups 2 are integrally formed into a ring-shaped reflective lamp holder. A first LED lamp bead 3 is mounted on the bottom of each first conical reflective cup 2 by an existing fixing method. A first optical lens 4 is mounted on the top of each first conical reflective cup 2 by an existing fixing method. The first optical lens is a 60-degree lens, which is used to match the first LED lamp bead 3 with a divergence angle of 120 degrees, so that the first optical lens 4 reduces the divergence of the light of the first LED lamp bead 3 in the invalid space, so that more than about 70% of the overall light is concentrated on the flag 91. Under the same luminous flux, it obtains higher illumination and range than the flagpole lamp with the same parameters on the market, so that the final lighting effect is greatly improved.

[0025] Furthermore, a ring light strip 6 for illuminating the decorative piece 92 installed on the top of the flagpole 1 is provided on the top of the lamp housing 1 , and the ring light strip 6 is electrically connected to the control board.

[0026] As Figure 1 and Figure 5 shown, the ring light strip 6 is actually a ring-shaped LED light strip, which is composed of a plurality of second LED beads 61 evenly distributed at intervals. Figure 1 The number of the second LED beads 61 shown is six. The ring light strip 6 is electrically connected in parallel with the first LED bead 3 and emits light or goes out simultaneously with the first LED bead 3. The design of adding the ring light strip 6 enables the flagpole light to achieve the effect of dual use of one light, which can not only illuminate the objects (such as the flag 91) below the lamp housing 1, but also optically decorate the decorative parts 92 above the lamp housing 1.

[0027] Furthermore, in order to obtain a better color effect, both the first LED bead 3 and the second LED bead 61 are RGB beads that can emit several colors. Under the control of an external wireless remote controller and a control board, they can be switched to different colors according to the changes or needs of the environment to embellish the flag 91 and the decorative parts 92.

[0028] Furthermore, a daylight sensor 12 for controlling the first LED bead 3 to turn on or off is arranged on the lamp housing 1, and the daylight sensor 12 is electrically connected to the control board.

[0029] As Figure 1 shown, the daylight sensor 12 is installed on the top plane of the lamp housing 1 or on the arc surface of its side wall by existing methods such as screws or buckles. It can sense the change of daylight. When the light becomes dark to a preset threshold value, it indirectly controls the first LED bead 3 and the ring light strip 6 to light up through the control board to achieve an automatic sensing effect.

[0030] Furthermore, a plurality of second conical reflecting cups are arranged at the bottom of the lamp housing 1. A third LED bead 7 is arranged at the thin-caliber end of the second conical reflecting cup, and a second optical lens 8 for converging the light emitted by the third LED bead 7 onto the flag is arranged at the thick-caliber end of the second conical reflecting cup; the third LED bead 7 is electrically connected to the control board.

[0031] As Figure 5As shown, a second conical reflector cup (not shown in the attached drawings) is also installed at the edge of the bottom plane of the lamp housing 1 in an existing manner. A plurality of second conical reflector cups are integrally formed into an annular reflector base. At the bottom of each second conical reflector cup, a third LED lamp bead 7 is installed in an existing fixing manner, and at the top of each second conical reflector cup, a second optical lens 8 is installed in an existing fixing manner. The structure of the second conical reflector cup is the same as that of the first conical reflector cup and is located inside the first conical reflector cup 2 (the side close to the mounting hole 11). The angles of the second conical reflector cup and the first conical reflector cup for reflecting light are different, so that the positions of the light irradiated on the flag 91 are different. The light emitted by the third LED lamp bead 7 is located inside the flag 91 close to the flagpole 9 after passing through the second conical reflector cup and the second optical lens 8; the light emitted by the first LED lamp bead 3 is located outside the flag 91 close to the flagpole 9 after passing through the first conical reflector cup 2 and the first optical lens 4. By installing the third LED lamp bead 7, the second conical reflector cup and the second optical lens 8 on the bottom plane of the lamp housing 1, different irradiation ranges can be diffused to adapt to flags 92 of different sizes. The third LED lamp bead 7 is also an RGB lamp bead and adopts a circuit independent of the first LED lamp bead 3. When it emits light of a different color from the first LED lamp bead 3, it can create an atmosphere with different color levels and improve the visual experience.

[0032] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
