Description

Technical Field

[0001] The utility model relates to the field of light strips, in particular to an LED light strip that is convenient for heat dissipation. Background Art

[0002] Light strips are a type of LED lighting product. They typically incorporate LEDs onto a flexible printed circuit (FPC) or PCB, earning their name from their resemblance to a ribbon. They offer a cool light source, low heat generation, and high energy efficiency. They have a long service life, typically 80,000 to 100,000 hours, and are energy-efficient and environmentally friendly, making them widely used in various decoration industries.

[0003] Light strips have diverse uses. They can serve as decorative aids, enhancing the overall appearance of a room with a more beautiful and layered look. For example, ceiling light strips can make a space more airy, bright, and elegant, highlighting the extraordinary grandeur of a luxurious residence. Cabinet light strips can effectively reduce the sense of enclosure within the interior without affecting the visual experience due to the darkness of the cabinets. Light strips in kitchen wall cabinets are not only aesthetically pleasing but also provide essential background lighting. Cleverly applying light strips to the background walls of living rooms and bedrooms can create an elegant and restrained style. Light strips can also be concealed, creating unique shapes that follow the contours of the space, enriching the spatial lighting environment, adding a sense of three-dimensionality and layering, and creating an atmosphere.

[0004] Heat dissipation is a key issue in existing LED light strip technology. Traditionally, heat dissipation is achieved by creating vents in the light housing. However, this approach has significant drawbacks. While these vents effectively dissipate heat within the light strip, they also allow impurities such as air, moisture, and dust to easily enter the housing. Once inside, these impurities can adhere to the LED light source, affecting its performance and potentially accelerating its aging, shortening its lifespan. This effect is particularly pronounced in humid or dusty environments. Utility Model Content

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A LED light strip that is easy to dissipate heat includes a flexible lamp shell and an LED light source.

Two adjacent scattering strips are parallel to each other, and the cross-section of the scattering strips is trapezoidal.

[0009] Furthermore, the bottom surface of the flexible lamp housing is provided with adhesive for adhering the flexible lamp housing to an object, and the surface of the adhesive is covered with release paper.

[0010] Furthermore, plugs are provided at both ends of the flexible lamp housing, and the plugs are used to seal the two ports of the light-emitting cavity. Terminals are provided on the plugs, and the flexible circuit board can be conductively connected to the terminals.

[0011] Furthermore, the plug is connected to a driver for controlling the light emission of the LED lamp beads.

[0012] Furthermore, the two plugs are respectively provided with a card block and a card slot, and the adjacent plugs can be combined by engaging the card block through the card slot.

[0013] Furthermore, the inner wall of the positioning groove is provided with heat dissipation silicone grease, and the heat of the flexible circuit board can be transferred to the heat-conducting base through the heat dissipation silicone grease.

Since the heat-conducting columns and the heat dissipation holes are closely matched, an effective barrier is formed, which can effectively prevent external impurities such as air, moisture and dust from entering the interior of the lamp shell, thereby protecting the LED light source and extending its service life.

The plurality of LED lamp beads 4 are evenly arranged along the length direction of the flexible circuit board 3. The plurality of lamp beads are connected in series through the flexible circuit board 3. A heat-conducting base 5 is provided in the flexible lamp housing 1. The heat-conducting base 5 is provided with a positioning groove 6. The flexible circuit board 3 can be set in the positioning groove 6. The inner wall of the light-emitting cavity 2 is provided with a plurality of The heat dissipation holes 7 are evenly arranged, and the surface of the thermal base 5 is provided with thermal conductive columns 8. The thermal conductive columns 8 can be paired and inserted into the heat dissipation holes 7. The thermal conductive columns 8 extend to the surface of the flexible lamp housing 1 at the end away from the thermal base 5. The thermal conductive columns 8 are tightly matched with the heat dissipation holes 7. The thermal base 5 can absorb heat from the light-emitting cavity 2 and dissipate the heat to the outside of the flexible lamp housing 1 through the thermal conductive columns 8. The inner wall of the positioning groove 6 is provided with thermal grease 9. Heat from the flexible circuit board 3 can be transferred to the thermal base 5 through the thermal grease 9, further enhancing the heat transfer efficiency between the flexible circuit board 3 and the thermal base 5. The thermal grease 9 has excellent thermal conductivity and can quickly transfer heat from the flexible circuit board 3 to the thermal base 5, and dissipate it through the thermal conductive columns 8 and heat dissipation holes 7.

[0022] The present embodiment provides an LED light strip that facilitates heat dissipation. A heat-conducting base 5 is provided within a flexible lamp housing 1, and heat-conducting columns 8 are provided on the heat-conducting base 5. The heat-conducting columns 8 can be paired and inserted into the heat dissipation holes 7. The heat generated by the LED light source can be quickly transferred to the outside of the flexible lamp housing 1 through the heat-conducting base 5 and the heat-conducting columns 8, thereby greatly improving the heat dissipation efficiency. Since the heat-conducting columns 8 closely cooperate with the heat dissipation holes 7, an effective barrier is formed, which can effectively prevent external impurities such as air, moisture, and dust from entering the interior of the lamp housing, thereby protecting the LED light source and extending its service life.

The light-scattering strips and the lampshade 10 are integrally formed through an injection molding process. By providing the lampshade 10 on the surface of the flexible lamp housing 1 and evenly disposing the light-scattering strips on the end of the lampshade 10 near the lamp beads, the light-scattering effect of the LED light strip is enhanced, making the light softer and more uniform, while also improving the aesthetics and applicability of the LED light strip.
