Including both sides of rural rivers, coastal cliff boundaries, traffic tunnels, bridge holes, etc., all need to add luminous elements.

[0003] At present, a Chinese patent with authorization announcement number CN211088264U discloses an LED light strip, in which an extruded plastic layer covers and wraps the light strip body, and the light strip body includes a substrate and a flip-chip LED chip. Therefore, when preparing the LED light strip, the flip-chip LED chip is directly fixed on the substrate, and then the obtained light strip body is extruded. The volume of the flip-chip LED chip is much smaller than that of the LED lamp bead, so the arrangement can be more dense, which can make the final LED light strip form a linear light source.

[0004] However, when this type of LED light strip is used in a fire safety escape passage, once a power outage occurs, it will not be able to illuminate directly and cannot play a role in continuous lighting guidance.

[0029] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0030] An LED combined with long afterglow luminous light strip device comprises an LED luminous strip 4, a U-shaped silicone substrate layer 1 and a photoinduced long afterglow luminous layer 2. The long afterglow luminous layer is made of aluminosilicate luminescent material and transparent resin, and thus has good elasticity. The U-shaped silicone substrate layer 1 is white and also has elasticity.

[0031] The photoinduced long afterglow luminous layer 2 is fixedly connected to the U-shaped silicone substrate layer 1 to form a positioning cavity 3, and the LED light strip 4 is arranged in the positioning cavity 3. Since the photoinduced long afterglow luminous layer 2 and the U-shaped silicone substrate layer 1 are both elastic, they have a good protective effect on the LED light strip 4 and are not easily damaged by falling.

[0032] The side of the photoinduced long afterglow luminescent layer 2 facing away from the U-shaped silicone substrate layer 1 has an arc-shaped convex portion 21 .

[0033] The photoinduced long afterglow luminous layer 2, the U-shaped silicone substrate layer 1 and the LED luminous strip 4 are all in the shape of long strips and are arranged in parallel.

[0034] A connecting section 31 extending into the positioning cavity 3 is integrally provided on the photoinduced long afterglow luminescent layer 2 .

[0035] The position of the arc-shaped protrusion 21 is taken as the upper side. The LED light strip 4 includes a circuit board 41 and lamp beads 42. The circuit board 41 is arranged in the positioning cavity 3. A plurality of lamp beads 42 are fixed on the circuit board 41 and arranged along the length direction of the circuit board 41. The distance between two adjacent lamp beads 42 is 8 mm. The lamp beads 42 are arranged opposite to the connecting section 31, that is, the lamp beads 42 face the side of the U-shaped silicone substrate layer 1. Therefore, the lamp beads 42 emit light laterally. Compared with the traditional method of arranging the lamp beads 42 upward, the energy storage of the photoinduced long afterglow light-emitting layer 2 is more uniform, that is, the light emission of the photoinduced long afterglow light-emitting layer 2 can be more uniform, and it is not easy to have obvious light spots.

[0036] A lower support section 51 is integrally connected to the U-shaped silicone substrate layer 1, and an upper support section 52 corresponding to the lower support section 51 is integrally connected to the photoinduced long afterglow luminous layer 2, and both the lower support section 51 and the upper support section 52 are in contact with the side of the circuit board 41 facing away from the lamp beads 42. A heat dissipation area 5 is formed between the circuit board 41, the lower support section 51, the upper support section 52 and the inner wall of the positioning cavity 3 to improve the heat dissipation performance of the circuit board 41, and when subjected to a lateral impact, the heat dissipation area 5 can absorb energy without causing the circuit board 41 to be deformed or damaged, thereby greatly improving the protection of the LED light strip 4.

[0037] An extension section 61 is integrally provided on the side of the photo-induced long afterglow luminous layer 2 facing the positioning cavity 3, and the extension section 61 contacts the side wall of the lamp bead 42. The extension section 61 is located on the side of the circuit board 41 facing the lamp bead 42 and contacts the circuit board 41; an integral limiting section 62 is provided on the side of the U-shaped silicone substrate layer 1 facing the positioning cavity 3, and the limiting section 62 is located on the side of the circuit board 41 facing the lamp bead 42 and contacts the circuit board 41.

[0038] The circuit board 41 can maintain a stable posture through the joint action of the extension section 61, the limiting section 62, the upper support section 52, and the lower support section 51, so that the lamp bead 42 can remain stable. The side of the circuit board 41 facing the lamp bead 42 is white.

[0039] A supplementary section 63 is integrally connected to the connecting section 31 . The cross section of the supplementary section 63 is arranged in a Z shape and is laid along the inner wall of the U-shaped silicone substrate layer 1 and the limiting section 62 .

[0040] Accordingly, when the LED light strip 4 is powered on, the lamp bead 42 emits light, which irradiates the supplementary section 63, the extension section 61, the photoinduced long afterglow luminescent layer 2, and the connecting section 31, or part of the light falls on the circuit board 41 after reflection. Since the circuit board 41 and the U-shaped silicone substrate layer 1 are both white, the light will be reflected again, so that most of the energy is absorbed by the photoinduced long afterglow luminescent layer 2, thus having extremely high energy storage efficiency. After the lamp bead 42 stops emitting light, the photoinduced long afterglow luminescent layer 2 can keep emitting light for a long time.

[0041] A placement groove 631 is formed on the supplementary section 63 , and the inner wall of the placement groove 631 abuts against the side wall of the lamp bead 42 .

[0042] A light-filling groove 7 is provided on the side wall of the U-shaped silicone substrate layer 1, and the light-filling groove 7 is arranged along the length direction of the U-shaped silicone substrate layer 1. The light-filling groove 7 is connected to the heat dissipation area 5, and a light-filling strip 71 is fixedly connected in the light-filling groove 7. The material of the light-filling strip 71 is the same as that of the photoinduced long afterglow luminescent layer 2.

[0043] The circuit board 41 of the LED light strip 4 is connected to a relay (not shown in the figure), and the relay is connected to a timer (not shown in the figure) to enable the LED light strip 4 to emit light intermittently. Since the relay and the timer are prior art, they are not described in detail in this embodiment.

[0044] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
