Description

Technical Field

[0001] The utility model relates to the field of light strips, in particular to a heat-resistant LED light strip. Background Art

[0002] Light strip is the abbreviation of LED light strip, which refers to the assembly of LEDs on a strip-shaped FPC (flexible circuit board) or PCB hard board. It is named because its product shape is like a strip. The light strip is soft and bendable, and can be cut at will. It is widely used in furniture, automobiles, advertising, lighting, ships, bars and other industries.

[0003] The light strip is often bonded to the installation interface with double-sided tape. The light strip is in close contact with the installation interface, and the heat dissipation generated during operation is limited, which will cause the temperature of the light strip to rise. The bonding ability of the double-sided tape will decrease due to heat transfer, affecting the installation firmness of the light strip (application number 202322306594.6 mentioned this technical problem in the background technology). The purpose of the utility model is to propose a new light strip structure to solve the above-mentioned technical problem. Utility Model Content

[0004] The purpose of the utility model is to provide a heat-resistant LED light strip to solve the problems mentioned in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a light strip main body, a fixed seat, a movable seat, a connecting piece and an adhesive layer, the fixed seat is formed with an opening for the light strip main body to pass through, the light strip main body is located inside the opening and is folded to form a folding portion, the movable seat and the fixed seat are alternately located on the light strip main body, the movable seat is connected to the light strip main body, the connecting piece is located below the movable seat, both sides of the connecting piece are connected to the bottom surface of the movable seat through folded thermal bimetallic strips, and the adhesive layers are respectively located on the fixed seat and the bottom surface of the connecting piece.

[0006] In order to optimize the above technical solution, further measures are taken as follows: a limiting ring is formed on the bottom surface of the light strip main body at the folding part, a pin is formed on the inner side of the opening, the limiting ring is sleeved on the pin and forms a rotating pair with the pin. The purpose of the setting is to limit the folding part within the opening through the cooperation of the limiting ring and the pin.

[0007] As a further improvement of the above technical solution: it also includes soft magnetic sheets, which are connected to the bottom surface of the light strip body and are located on both sides of the folding portion. The soft magnetic sheets on both sides of the folding portion attract each other, and the mutual attraction between the soft magnetic sheets realizes the resetting of the folding portion after unfolding.

[0008] As a further improvement of the technical solution: the fixed seat and the movable seat are both transparent, and the transparent material can prevent the fixed seat and the movable seat from blocking the light emitted by the main body of the light strip.

[0009] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0010] The utility model provides a heat-resistant LED light strip, which cooperates with the thermal bimetallic strip through a folding portion. When the temperature of the light strip rises, the main body of the light strip will be supported by the thermal bimetallic strip, thereby increasing the distance between the main body of the light strip and the adhesive layer, thereby preventing the adhesive layer from being heated and having its adhesive ability reduced, resulting in poor installation firmness of the light strip.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] Example

[0016] See also Figure 1 The utility model provides a heat-resistant LED light strip, including a light strip body 1, a fixing seat 2, a movable seat 3, a connecting sheet 4, an adhesive layer 5 and a soft magnetic sheet 6. The fixing seat 2 is formed with an opening 201 for the light strip body 1 to pass through. The light strip body 1 is located inside the opening 201 and is folded to form a folding portion 101. A limiting ring 102 is formed on the bottom surface of the light strip body 1 at the folding portion 101. A pin 202 is formed inside the opening 201. The limiting ring 102 is sleeved on the pin 202 to form a rotating pair with the pin 202.

[0017] The movable seat 3 and the fixed seat 2 are alternately located on the light strip main body 1, the movable seat 3 is connected to the light strip main body 1, the fixed seat 2 and the movable seat 3 are both transparent, and the specific transparent material used is not the technical content that the applicant wants to protect, so it will not be further explained.

[0018] The connecting piece 4 is located below the movable seat 3 , and both sides of the connecting piece 4 are connected to the bottom surface of the movable seat 3 through folded thermal bimetallic strips 401 .

[0019] The adhesive layer 5 is respectively located on the bottom surface of the fixing seat 2 and the connecting piece 4 , and the installation of the light strip is achieved by bonding and fixing the adhesive layer 5 to the installation surface of the light strip.

[0020] The soft magnetic sheets 6 are connected to the bottom surface of the light strip body 1 and are located on both sides of the folding portion 101. The soft magnetic sheets 6 on both sides of the folding portion 101 attract each other, and the folding portion 101 is reset after unfolding through the mutual attraction between the soft magnetic sheets.

[0021] The thermal bimetallic strip 401 refers to a metal strip in the prior art that is composed of two metal strips with different thermal expansion coefficients. Due to the difference in thermal expansion coefficients, it will bend and deform to one side when the temperature rises. During implementation, technicians can select thermal bimetallic strips of different materials according to actual needs. Thermal bimetallic strips of different materials have different deformation temperatures.

[0022] Working principle: The light strip is fixed by bonding the fixing seat 2, the connecting piece 4 and the installation interface with the adhesive layer 5, thereby realizing the installation of the light strip. Since the fixing seat 2 and the movable seat 3 are both transparent, the fixing seat 2 and the transparent seat will not block the light emitted by the light strip body 1 and affect the visual effect.

[0023] When the heat generated by the light strip main body 1 continues to accumulate and causes the temperature to rise, the thermal bimetallic strip 401 will bend, causing the distance between the movable seat 3 and the connecting plate 4 to increase, causing the movable seat 3 to move upward, and the upward moving seat 3 will drive the folding part 101 to unfold. At this time, the light strip main body 1 of the folding part 101 and the light strip main body 1 of the movable seat 3 are both away from the adhesive layer 5, which can prevent the adhesive layer 5 from losing its adhesion due to heat, resulting in a decrease in the installation stability of the light strip.

[0024] After the main body 1 of the light strip is turned off, the temperature of the thermal bimetallic strip 401 drops and will be restored. At this time, the folding parts 101 will be attracted by the soft magnetic sheets 6 and will be close to each other and folded.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
