Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of LED lamp strip especially relates to a length adjustable LED linear lamp strip. BACKGROUND

[0002] In the fields of building, indoor and outdoor decoration, stage lighting design and various commercial display, LED lamp strip has been widely used because of its advantages of energy saving, rich color, flexible modeling and the like. Whether it is used for outlining the building profile, creating indoor atmosphere light or adding visual effect for stage performance and commercial display, LED lamp strip plays an important role and its market demand continues to grow.

[0003] At present, the common LED lamp strip has some deficiencies in actual use. The traditional LED lamp strip is usually of fixed length specification. When the length of the lamp strip does not match the actual demand length during installation, the lamp strip often needs to be cut or spliced. The cutting operation may damage the internal circuit of the lamp strip, affecting its normal light emission and service life, and the cut lamp strip cannot be used again, causing material waste. The splicing operation is not only tedious, but also needs to use additional connectors or welding tools, increasing the installation difficulty and cost, and may cause poor contact due to loose connection, resulting in flickering or non-lighting problems. In the installation of the lamp strip, some existing lamp strips lack effective auxiliary positioning devices. During installation, especially in some scenes requiring accurate installation position, such as installation on complex-shaped building structures or fine indoor decoration lines, the operator usually can only hold the lamp strip for fixation, which is difficult to ensure the accuracy and stability of the installation position of the lamp strip. This not only easily causes the lamp strip to fall off during installation, requiring repeated adjustment and reinstallation, reducing work efficiency, but also may cause the fixed position of the lamp strip to deviate, affecting the final light effect and overall aesthetic degree. In addition, the lamp strip is easy to adsorb dust and other impurities during use. With the passage of time, the dust accumulated on the lamp strip will affect its heat dissipation performance, thereby reducing the light emission efficiency, and even may cause the lamp strip to be damaged due to overheating. The existing lamp strip lacks cleaning devices when it is wound and stored, and dust and impurities are easy to enter the internal part of the lamp strip with winding, which may cause jamming or damage to the internal elements of the lamp strip during next use.

[0004] To this end, the present application proposes a length adjustable LED linear lamp strip to solve the technical problem. UTILITY MODEL CONTENTS
