Description

Technical Field

[0001] The utility model relates to the technical field of lamp accessories, in particular to a LED lamp belt housing with a protective structure. Background Art

[0002] Led light strip is a commonly used lighting fixture, widely used in indoor and outdoor lighting, and its application scenarios are also expanding more and more. Among them, landscape waterscape and fish tank landscaping are an emerging application scenario. This scenario requires the Led light strip to have excellent waterproof performance. Although the currently commonly used closed shells have good waterproof properties, the ends of such closed shells are generally not sealed and are connected to the atmosphere. When used underwater for a long time, a small amount of condensation water is likely to be generated in the shell. If the substrate and chip of the Led light strip are completely sealed with glue, for high-power Led light strips, complete glue sealing will affect heat dissipation, and long-term use will easily accelerate the aging of the shell.

[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] As attached Figure 1 , 2 As shown, the LED light strip housing with a protective structure involved in the utility model comprises a lower housing 1, a hard light-transmitting support cover 2, an upper housing 3, and a water-absorbing film 4.

[0016] The lower shell 1 is a U-shaped structure made of hard plastic material. The hard light-transmitting support cover 2 is arranged on the upper part of the lower shell 1 to cover the opening of the lower shell 1. The upper shell 3 is arranged on the outside of the hard light-transmitting support cover 2 and is made of light-transmitting glue. In manufacturing, the hard light-transmitting support cover 2 is placed on the lower shell 1 and covered with light-transmitting glue material to form the upper shell 3.

[0017] The light strip L is arranged in a cavity enclosed by a lower shell 1 and a hard light-transmitting support cover 2. The substrate and the surface of the LED chip of the light strip L are covered with a waterproof film. A gap is arranged between the light strip L and the hard light-transmitting support cover 2 and the lower shell 1. Water-absorbing films 4 are respectively arranged in the gaps, wherein the upper water-absorbing film 4 is provided with an opening for the LED chip to leak out. The water-absorbing film 4 can absorb a small amount of condensed water produced in the outer shell.

[0018] The material of the water-absorbing film 4 can be polyester (PES) film or polyamide (PA) film.

[0019] In order to achieve a gap between the bottom surface of the LED chip and the lower shell 1 , a plurality of supporting protrusions 12 are arranged on the bottom surface of the inner cavity of the lower shell 1 , and the substrate of the light strip L is arranged on the supporting protrusions 12 .

[0020] Furthermore, a water-proof layer 41 may be provided on the bottom surface of the upper water-absorbing film 4 to avoid corrosion of the substrate.

[0021] When in use, the end of the LED light strip that is not underwater can be left open and set inside an electrician's box, so that the gap between the light strip L and the hard light-transmitting support cover 2 and the lower shell 1 is connected to the atmosphere, which can effectively dissipate heat and volatilize the moisture in the water-absorbing film 4. Figure 3 As shown, the end of the LED light strip housing that is not underwater can also be provided with an end cap 5, the end cap 5 is a cavity structure with an opening on one side, the opening is consistent with the cross-sectional shape and size of the lamp housing, the lamp housing can be inserted into the inner cavity of the end cap 5, the bottom surface of the end cap 5 is provided with an opening 51 at the position of the water absorption film 4, and a wire hole 52 is provided at the connection position of the light strip L. Since the gap of the water absorption film is large, even if the opening 51 is blocked, an airtight seal will not be formed.

[0022] If there is an end located underwater, it can be sealed by injecting glue.

[0023] Furthermore, in the length direction of the light strip, the cross-section of the hard light-transmitting support cover 2 is arc-shaped, and outward horizontal protrusions 21 are provided at both ends of the lower side, and grooves 11 are provided on the inner sides of the tops of the two opposite side surfaces of the lower shell 1, and the horizontal protrusions 21 are arranged in the grooves 11.
