Abstract

A flexible luminescent light bar with waterproof function. Through the heterogeneous waterproof secondary molding structure, the first molding is first formed by using a waterproof structure with high light transmission and high density to cover the flexible substrate and light-emitting elements. The second molding uses an optical structure with a lower density and a geometric structure to cover the waterproof structure to prevent direct entry of water vapor, thereby prolonging the service life of the flexible light strip.

Description

Flexible light strip with waterproof function

A flexible light strip, especially a flexible light strip with waterproof function.

Nowadays, light-emitting light strips are used in both swimming pools and garden landscaping, but the existing light-emitting light strips will have water seepage problems after long-term use, or because they cannot be completely sealed, water vapor or foreign objects will invade through the breach. The problem of water leakage or short circuit will be caused, which will lead to problems such as reduced service life and easy damage of the light-emitting light bar; accordingly, how to prolong the life of the light-emitting light bar when it is used underwater is a problem to be solved.

In view of the above-mentioned problems, the author of this article has conducted research and improvement on the structure of the luminous light bar based on years of experience in related industries; therefore, the main purpose of this creation is to provide an extended luminous light bar for underwater use. Long life flexible light strips.

In order to achieve the above purpose, this invention firstly arranges a flexible substrate and a light-emitting element in an accommodating space inside the waterproof structure, and then implements An optical structure with a diffusing colloid and a reflective colloid completely covers the waterproof structure, wherein the waterproof structure and the optical structure are made of silicone with different proportions and densities. When used underwater for a long time, the difference in density can delay the penetration of water vapor into the interior, thereby prolonging the service life of the flexible light strip.

In addition, the connection cable of the flexible luminescent light bar of this creation is composed of a variety of silicone rubbers with different composition ratios, and a connection part is formed, and a water blocking unit connected with the waterproof structure is arranged inside the connection part. In this way, by Due to the compatibility of the material and the overall mechanism design, water vapor can be further prevented from entering the gap between the flexible light strip and the cable, thereby prolonging the service life of the flexible light strip.

In more detail, the side of the flexible substrate 11 that is not provided with the light-emitting element 12 is disposed on the side of the waterproof structure 13. On the inner wall, the waterproof structure 13 is made of light-transmitting silicon-containing compound (silicone) silicone or polymer material (IUPAC), such as polyurethane.

The optical structure 14 has a diffusing colloid 141 and a reflective colloid 142, so as to completely cover the waterproof structure 13. In more detail, in one embodiment, the diffusing colloid 141 is molded on the flexible substrate 11 and the light emitting element 12. On the outer wall of the waterproof structure 13, the reflective colloid 142 is formed on the remaining outer wall of the waterproof structure 13 without the diffusion colloid 141, wherein the diffusion colloid Body 141 is made of silica gel or its derivatives and optical powder (such as diffusion powder, fluorescent powder, etc.), but not limited thereto; reflective body 142 is made of silica gel or its derivatives and reflective material The high-reflectivity colloid is used to refract the light projected by the light-emitting element 12 , so that the light projected by the light-emitting element 12 can be projected according to the geometric structure of the optical structure 14 .

In addition, it is worth mentioning that both the waterproof structure 13 and the optical structure 14 can be made of silicone rubber, but the difference between the two is that the waterproof structure 13 can be made of silicone rubber with a higher density than the optical structure 14, so, When the waterproof flexible light bar 1 is used underwater for a long time, water vapor may slowly penetrate from the optical structure 14 into the waterproof flexible light bar 1, due to the waterproof structure The density of 13 is greater than that of the optical structure 14, which can further delay the direct entry of water vapor, thereby prolonging the service life of the flexible light-emitting light bar 1 with waterproof function.

In one embodiment, the outer wall of the optical structure 14 is provided with at least two grooves 143 for the flexible light-emitting light bar 1 with waterproof function to be buckled on the light bar fixing seat.

Please refer to "Fig. 5", which is another embodiment of this invention. As shown in the figure, the difference between this embodiment and the previous embodiment is that in order to respond to the flexible direction of the flexible substrate 11, the flexible substrate 11 is changed from a horizontal setting to a vertical setting, and is set on the inner wall of the waterproof structure 13 adjacent to the groove 143. As such, the diffusion gel 141 is formed on the waterproof structure 13 of the relatively flexible substrate 11 and the light-emitting element 12. In addition to being formed on the outer wall of the waterproof structure 13 adjacent to the flexible substrate 11 and the light-emitting element 12, the reverse The injection gel 142 is formed on the remaining outer wall of the waterproof structure 13 where the diffusion gel 141 is not formed.

As shown in the figure, one end of the flexible light-emitting light strip 1 with waterproof function of this creation is formed with a connecting part 17, and a cable C is assembled outside the connecting part 17. And there is a water blocking unit 171 inside, and the water blocking unit 171 is connected with the waterproof structure 13 to prevent water vapor from entering the gap between the flexible light bar 1 with waterproof function and the cable C. In the flexible light bar 1, the connection part 17 can be formed by extending the optical structure 14, and the connection part 17 and the cable C are both made of silicon rubber or its derivatives, and the water blocking unit 171 is made of silicon-containing Compound (silicone) silicone or polymer material (IUPAC), such as polyurethane or thermosetting plastics.

In addition, it is worth mentioning that although the waterproof structure 13, the optical structure 14, the connecting part 17, the water blocking unit 171, and the cable C are composed of different proportions of silicone rubber, it is precisely because each component has a silicone rubber component. It has extremely high compatibility, therefore, there will be no gap between them when combined, which can further prevent water vapor from directly entering, thereby prolonging the service life of the flexible light-emitting light bar 1 with waterproof function.

To sum up, it can be seen that the flexible light strip with waterproof function of this creation mainly uses a heterogeneous waterproof secondary molding structure. The first molding uses a waterproof structure with high light transmission and high density. flexible substrates and The light-emitting element is covered, and the second molding uses an optical structure with a low density and a geometric structure to cover the waterproof structure, thereby preventing direct entry of water vapor, thereby prolonging the service life of the flexible light-emitting light strip According to this, after the implementation of this creation, it can indeed achieve the purpose of providing a flexible light strip with waterproof function that can meet the needs of use, and has good weather resistance and water resistance.

However, what is described above is only a preferred embodiment of this creation, and is not used to limit the scope of implementation of this creation; anyone who is familiar with this skill can make equal changes and modifications without departing from the spirit and scope of this creation , should be covered within the patent scope of this creation.
