DETAILED DESCRIPTION

[0020] The present invention is further described in detail below with reference to the embodiments:

[0021] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figures 1 to 3 As shown,

[0023] A multi-color COB light strip with an anti-glare function comprises: a substrate 1 and an encapsulation shell 2, two rows of LED chips 3 are arranged side by side on the substrate 1, and an encapsulation colloid 4 capable of encapsulating the two rows of LED chips 3 is further provided between the substrate 1 and the encapsulation shell 2, the top of the encapsulation colloid 4 has a push surface 41, and a mounting cavity 500 is provided between the push surface 41 and the encapsulation shell 2, the multi-color COB light strip also comprises a deformable scattering layer 6, the bottom push surface 41 of the scattering layer 6 is in contact with the top push surface 41, and the top of the scattering layer 6 is further provided with a plurality of scatterers 61 capable of allowing light emitted by the LED chips 3 to pass through, and when the scattering layer 6 is arranged in the mounting cavity 500, the scattering layer 6 is bent so that the plurality of scatterers 61 are arranged obliquely along the push surface 41.

[0024] In this embodiment, the scattering layer 6 is bent and fits onto the top surface of the encapsulation colloid 4 through the top pushing surface 41 of the encapsulation colloid 4. The scattering body 61 is correspondingly arranged so that the light emitted by the two rows of LED chips 3 passes through the scattering body 61. The scattering body 61 causes the light emitted by the LED chips 3 to form soft diffuse reflected light, forming a soft and natural diffuse light effect, thereby avoiding glare and affecting the user's observation comfort.

[0025] The two sides of the push surface 41 are straight lines, and the middle part of the push surface 41 is an arc-shaped surface. The setting of the push surface 41 can squeeze the scattering layer 6, causing the scattering layer 6 to deform, and the scattering body 61 can be evenly distributed around the LED chip 3.

[0026] The scatterer 61 is hemispherical, and the top of the scatterer 61 has an arc surface. The scatterer 61 is filled with light diffusion powder. The light diffusion powder can make the light softer when it is emitted and avoid glare.

[0027] The interior of the package 2 is coated with multiple layers of phosphor glue 21. The color temperature of the phosphor glue 21 ranges from 3200K to 6500K, with the lower color temperature phosphor glue 21 applied below the higher color temperature phosphor glue 21. The LED chips 3 are arranged in two rows, side by side, to ensure uniform illumination of the COB light strip, eliminating dark areas during illumination. The phosphor glue 21 can be composed of one or more layers of phosphor glue 21 with different color temperatures, resulting in a smooth, spot-free light, excellent heat dissipation, and uniform illumination, avoiding glare and making the light emitted by the light strip softer.

[0028] The substrate 1 includes a substrate body 11 and a reflective layer 12 connected to the substrate body 11. The two rows of LED chips 3 are connected to the substrate body 11. The reflective layer 12 is connected to the side of the substrate body 11 away from the LED chips 3, and the reflective layer 12 is provided with two convex edges 121 arranged obliquely upward, and a reflective surface 122 is provided on the convex edge 121.

[0029] A heat dissipation film 13 is further provided between the reflective layer 12 and the substrate body 11. The heat dissipation film 13 is provided to guide heat dissipation.

[0030] The heat dissipation film 13 is made of graphene material, and its upper surface is adhered to the underside of the substrate body 11 with adhesive, corresponding to the two rows of LED chips 3. The bottom of the heat dissipation film 13 is adhered to the reflective layer 12 with glue. When the COB light strip is turned on for a long time, the heat dissipation film 137 is used to conduct heat generated by the LED chips 3 during operation, accelerating heat dissipation.

[0031] The reflective layer 12 is provided with a plurality of protruding teeth 123, and the packaging shell 2 is provided with a tooth portion 22 that can engage with the protruding teeth 123. The protruding teeth 123 and the tooth portion 22 are connected by adhesive. Due to the provision of the protruding teeth 123 and the tooth portion 22, the bonding area is increased, so that the substrate 1 and the packaging shell 2 are connected more tightly.

[0032] The reflective layer 12 is provided with a through hole 124. The cross section of the through hole 124 is arranged in a runway shape, which is convenient for heat dissipation and can also facilitate the bending of the COB light strip.

[0033] The materials of the reflective layer 12 and the packaging shell 2 are both IP68 waterproof materials. By wrapping each component in the reflective layer 12 and the packaging shell 2, the COB light strip can achieve IP68 waterproof, with good waterproof effect.

[0034] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
