[0004] As an improvement plan for traditional LED light strips, this type of prior art has good practical use effects, and has made important and reference-worthy improvements in the directions of reducing production costs, reducing pollution, and speeding up construction. However, cold light source LED light strips with low voltage and current generally cannot meet the lighting and color display requirements of medium or large landscape sculptures, and the light strips commonly used in the prior art cannot have perfect cooling conditions. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic cooling intelligent LED landscape lamp to solve the problem that the cold light source LED light strip with small voltage and current mentioned in the above background technology generally cannot meet the lighting and color display requirements of medium or large landscape sculptures, while the light strips commonly used in the prior art cannot have perfect cooling conditions.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic cooling intelligent LED landscape lamp, comprising a flexible LED light strip and LED lamp beads installed on the front of the flexible LED light strip, wherein the voltage and current in the semiconductor LED lamp beads are divided and limited by resistors, and the resistors are also installed on the light strip, and the flexible LED light strip also includes a shaping mechanism, and the shaping mechanism is used to keep the flexible LED light strip in a predetermined bending state, and the shaping mechanism includes a first metal strip, wherein the first metal strip is parallel to the axis of the flexible LED light strip, and the first metal strip is located on the side of the back of the flexible LED light strip.

[0007] Preferably, the shaping mechanism further comprises a second metal strip, which is also attached to the back of the flexible LED light strip and has a distribution direction different from that of the first metal strip.

[0008] Preferably, the second metal strip is a horizontal strip.

[0009] Preferably, the horizontal bar is made of a memory alloy material, the middle section of the horizontal bar is fixed to the back side of the flexible LED light strip, and the two ends of the horizontal bar are deformed after being exposed to high temperature.

[0010] Preferably, a hollow bag is installed on the back of the flexible LED light strip, wherein the hollow bag is connected to a fluid supply device, and the device is used to transport the fluid toward the hollow bag and perform non-contact heat exchange and cooling on the flexible LED light strip.

[0011] Preferably, the inner space of the hollow bag is divided into a fluid zone and an airflow zone, and the airflow zone is connected to the air holes opened at the edge of the hollow bag.

[0012] Preferably, the air flow area is used to generate a gas flow effect when pulsed fluid is intermittently introduced into the fluid area and promote air flow near the light strip through the air holes.

[0013] Preferably, the airflow area and the fluid area are separated by an elastic sheet, and the top and bottom ends of the elastic sheet are respectively sealed and fixed to the top wall and the bottom wall inside the hollow bag.

[0014] Preferably, the second metal strip comprises a flexible strip with a bottom end located inside the fluid cavity and a top end located on the front side of the flexible LED light strip.

[0015] Preferably, the inner section of the flexible strip is fixed on the elastic sheet, while the middle section of the flexible strip slides through the air hole whose inner diameter is larger than the middle section of the flexible strip.

[0016] Preferably, the flexible strip is also made of memory alloy material.

[0017] Compared with the existing intelligent LED landscape lights in the prior art, the beneficial effects of the present invention are: a new type of shaping mechanism is used to produce the effect of maintaining the predetermined required shape of the light strip, and the shaping mechanism is used to adapt to the heat dissipation requirements in various installation environments. At the same time, the above-mentioned shaping mechanism can be used in conjunction with the non-contact flow of the fluid to produce a further intelligent cooling effect, and there is no cooling dead corner, which is more suitable for the installation and cooling needs of landscape sculptures with more internal bends and folds, as shown in the following content.

[0018] 1. The use of the first metal strip in conjunction with the second metal strip can, on the one hand, utilize the metal strip's own flexibility, deformability and shape retention to assist the installation and positioning requirements of the light strip in the curved environment inside the landscape sculpture. On the other hand, the metal strip protrudes from the back of the light strip, and can achieve better heat conduction and cooling effects under different installation methods. Furthermore, the horizontal second metal strip design, in addition to achieving the effect of heat conduction, can also utilize the temperature-sensitive deformation of its memory alloy. When the staff cannot directly see whether the LED lamp beads are lit, the deformation of the horizontal strip can be used to quickly locate the damaged position of the lamp beads, thereby facilitating fixed-point replacement and maintenance without replacing the entire strip, which is more energy-saving and environmentally friendly.

[0019] 2. The structural design of the hollow bag can, on the one hand, utilize the gas or liquid flowing inside it for more efficient heat conduction and cooling, and on the other hand, can control the flow of the fluid to achieve a pulsed change in the fluid pressure inside the hollow bag, thereby utilizing the pressure change to guide the airflow area to produce the effect of guiding the airflow flow, and combined with fluid heat conduction, a better cooling effect can be achieved; Furthermore, the use of the flexible strip combined with its position design in the hollow bag can not only realize temperature-sensitive deformation to assist in locating the damaged lamp beads, but also realize auxiliary temperature conduction between the lamp beads and the fluid, and cooperate with the heat exchange of the fluid itself to achieve a better cooling effect, and there is no cooling dead corner. Compared with the traditional cooling method of using a fan at a fixed position to circulate air in the entire space inside the sculpture, the cooling is more targeted.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 11 , the present invention provides the following technical solutions: Embodiment 1: The solution disclosed in this embodiment is to solve the problem that most of the light strips in the LED landscape lights in the prior art can only be maintained in a given state by glue or other means, such as Figure 1-Figure 3As shown, it includes a flexible LED light strip 1 and an LED lamp bead 2 installed on the front side of the flexible LED light strip 1, wherein the voltage and current in the semiconductor LED lamp bead 2 are divided and limited via a resistor 3, and the resistor 3 is also installed on the light strip 1, and the flexible LED light strip 1 also includes a shaping mechanism, and the shaping mechanism is used to keep the flexible LED light strip in a predetermined bending state, and the shaping mechanism includes a first metal strip 4, wherein the first metal strip 4 is parallel to the axis of the flexible LED light strip 1, and the first metal strip 4 is located at the side position of the back side of the flexible LED light strip 1, and the shaping mechanism also includes a second metal strip, and the second metal strip is also attached to the back side of the flexible LED light strip 1, and the distribution direction is different from that of the first metal strip 4, and the solution provided by this scheme is to set a plurality of first metal strips 4 and the second metal strips 4 on the back side of the flexible LED light strip 1. Two metal strips, and because the distribution directions of the two groups of metal strips are different, when the light strip itself needs to be kept in different bending states in response to different installation positions, the deformation of the metal strips at different positions can be used to produce the effect of maintaining the specified bending state of the light strip, and after the installation of the flexible LED light strip 1 is completed, several metal strips attached to the back of the flexible LED light strip 1 can also play other roles. First, the good thermal conductivity of the metal is used to perform non-contact heat conduction and cooling of the lamp beads and resistors. At the same time, when the adhesive-backed installation is adopted, the metal strip protruding from the back of the light strip can be used to increase the contact area between the light strip and the adhesive as a whole to improve stability. At the same time, when using buckles or other fixing methods, the setting of several metal strips will also avoid the complete fit of the light strip and the installation surface of the landscape sculpture by separating the gaps, thereby further improving the cooling effect.

[0024] This solution is a further supplement to the above embodiment. When the lamp beads of the light strip inside the landscape sculpture are damaged by heat, if the light strip is connected in a way that the lamp beads are distributed toward the installation surface, the staff cannot quickly determine the location of the damaged lamp beads. Directly replacing the entire or multiple light strips will result in excessive costs. As a relatively basic solution, Figure 2-Figure 5 As shown, the second metal strip is a horizontal strip 5, which is made of a memory alloy material. The middle section of the horizontal strip 5 is fixed on the back of the flexible LED light strip 1, while the two ends of the horizontal strip 5 are deformed after high temperature. The horizontal strip 5 is used in conjunction with the first metal strip 4 to form a shaping mechanism, which can not only achieve the effects produced in the above-mentioned embodiments, but also utilize the high-temperature deformable characteristics of the horizontal strip 5 itself. When the front side of the light strip is used for installation with the mounting surface fitted, the staff can quickly determine the position of the semiconductor lamp beads 2 damaged by high temperature by observing the distribution pattern of the horizontal strip 5.

[0025] Embodiment 2: The solution disclosed in this embodiment is mainly to further solve the problem of insufficient cooling efficiency of smart LED landscape lights when used inside large-volume sculptures. A hollow bag 6 is also installed on the back of the flexible LED light strip 1, wherein the hollow bag 6 is connected to a fluid supply device, which is used to transport fluid toward the hollow bag 6 and perform non-contact heat exchange and cooling on the flexible LED light strip 1. When the internal temperature exceeds the threshold, the system controls fluid control devices such as fans or water pumps to transport relatively low-temperature airflow or liquid toward the interior of the hollow bag 6. At the same time, the above-mentioned fluid does not directly contact the lamp beads or other circuit parts, thereby avoiding leakage short circuits and other situations caused by the risk of leakage that may occur after using fluid cooling.

[0026] In this embodiment, the technical effect to be achieved is mainly reflected in the use of the change in the flow pressure of the fluid in the hollow bag 6 to achieve other effects, such as Figure 7-Figure 8 As shown, the internal space of the hollow bag 6 is divided into a fluid zone and an airflow zone 8, and the airflow zone 8 is connected to the air hole 9 opened at the edge of the hollow bag 6, wherein the airflow zone 8 is used to generate a gas flow effect when a pulsed fluid is intermittently introduced into the fluid zone and promote the air flow near the light strip through the air hole 9, and the airflow zone 8 and the fluid zone are separated by an elastic sheet 7, and the top and bottom ends of the elastic sheet 7 are respectively sealed and fixed to the top wall and the bottom wall inside the hollow bag 6. The flow pressure of the fluid in the hollow bag 6 is jointly controlled according to the fluid input rate at the input end and the discharge rate at the output end. Therefore, by this means, the water pressure in the hollow bag 6 can be in a pulsed change effect within a specified time period. In this process, the changing water pressure will directly act on On the elastic sheet 7 of elastic material, when the water pressure increases, the elastic sheet 7 expands outward, and when the water pressure decreases, it will sink inward to restore the deformation. In this process, the internal pressure of the airflow area 8 in the space outside the elastic sheet 7 will be in a state of intermittent change, thereby producing an effect of promoting airflow. The effect produced in this way is that it can produce an airflow flow effect through the air holes 9 near the flexible LED light strip 1, so that the low heat near the fluid cavity can exchange heat with the high heat near the lamp beads and improve the cooling effect. Compared with the traditional means of setting cooling equipment such as fans at a fixed position in the sculpture landscape, the airflow heat exchange and cooling effect achieved is better, and sufficient heat exchange can be carried out in some corners.

[0027] Embodiment 3: This embodiment discloses another solution of the second metal strip, which can produce a better heat conduction effect compared with the embodiment 1, such as Figure 9-11As shown, the second metal strip includes a flexible strip 10 whose bottom end is located inside the fluid cavity and whose top end is located on the front side of the flexible LED light strip 1. The inner section of the flexible strip 10 is fixed on the elastic sheet 7, and the middle section of the flexible strip 10 slides through the air hole 9 whose inner diameter is larger than its diameter. The flexible strip 10 is also made of a memory alloy material. Since the end of the flexible strip 10 is located in the fluid cavity, the flexible strip 10 itself has a good thermal conductivity effect, and the heat generated near the lamp bead is conducted to the fluid cavity, thereby achieving a better cooling and thermal conductivity effect. Furthermore, since it is also made of a memory alloy material, when a local lamp bead is overheated and damaged, the bend at its outer end will also deform and improve the effect of the staff.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
