Description

Technical Field

[0001] This utility model relates to the field of neon light technology, and more specifically, to a neon light that is integrally cast. Background Technology

[0002] Neon lights are light-emitting devices that rely on a light source located inside a panel to emit light, such as... Figure 3 As shown, existing neon lights generally include a panel, a base plate, a light strip with a light source, and a light-transmitting colloid. The base plate is installed on the back of the panel, the light strip is arranged in a groove in the panel according to a preset shape, and the shape of the light-transmitting colloid matches the shape of the light strip and is embedded in the panel. During manufacturing, the light strip and the light-transmitting colloid can be set into different shapes, such as various graphics or words. The light emitted by the light source can be projected through the light-transmitting colloid to produce different lighting effects. However, this type of neon light has the following shortcomings:

[0003] 1. The light-transmitting colloid and the panel are designed separately. During the preparation process, it is necessary to cut grooves in the panel and assemble the light-transmitting colloid into the grooves in the panel. The assembly is cumbersome, which reduces production efficiency and increases production costs. In addition, there are gaps between the light-transmitting colloid and the panel, resulting in poor sealing.

[0004] 2. In addition to installing the light strip, a base plate also needs to be installed on the back of the panel, making assembly more complicated and increasing production costs. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a neon light that is integrally cast.

[0006] To achieve the above objectives, this utility model provides an integrally cast neon light, including a neon light panel and a circuit board. The neon light panel includes a transparent resin layer, a light-transmitting colored resin layer, and a light-shielding resin layer connected sequentially from the outside to the inside. The transparent resin layer, the colored resin layer, and the light-shielding resin layer are injection molded in layers to form an integral panel structure. A light-transmitting groove extending to the back of the colored resin layer is provided on the back of the light-shielding resin layer. The circuit board is installed on the back of the light-shielding resin layer, and the circuit board is provided with a plurality of LED light sources, each of which is located in a corresponding light-transmitting groove of the light-shielding resin layer.

[0007] Preferably, the light-shielding resin layer is a black light-shielding resin layer.

[0009] Preferably, the circuit board is fixed to the back of the light-shielding resin layer by adhesive bonding or screw fastening.

[0010] Preferably, the circuit board is an aluminum-based circuit board.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The neon light panel of this utility model includes a transparent resin layer, a light-transmitting colored resin layer, and a light-shielding resin layer connected sequentially from the outside to the inside.

[0021] like Figure 1 and Figure 2 As shown, the neon light panel 1 may include a transparent resin layer 11, a light-transmitting colored resin layer 12, and a light-shielding resin layer 13 connected sequentially from the outside to the inside. The transparent resin layer 11, the colored resin layer 12, and the light-shielding resin layer 13 can be injection molded in layers to form an integral panel structure. A light-transmitting groove 14 extending to the back of the colored resin layer 12 is provided on the back of the light-shielding resin layer 13.

[0022] In this embodiment, the transparent resin layer 11 and the colored resin layer 12 can be configured with different shapes and patterns.

Setting different colors for the colored resin layer is beneficial for the neon lights to emit different colors of light. The light-shielding resin layer 13 can preferably be configured as a black light-shielding resin layer, as black has a better light-shielding effect.

[0023] In specific preparation, the transparent resin layer 11, the colored resin layer 12, and the light-shielding resin layer 13 can be made of epoxy resin, unsaturated resin, or other various resins.

[0024] like Figure 2 As shown, a recessed circuit board receiving groove 15 can also be provided on the back of the light-shielding resin layer 13.

[0025] like Figure 1 As shown, the circuit board 2 is mounted on the back of the light-shielding resin layer 13 and is located in the circuit board receiving groove 15. Each LED light source 3 is located in a corresponding light-transmitting groove 14 of the light-shielding resin layer 13. The light emitted by the LED light source 3 can pass through the colored resin layer 12 and the transparent resin layer 11 and be projected out.

[0026] In this embodiment, the circuit board 2 is preferably an aluminum-based circuit board. The circuit board 2 can be fixed to the back of the light-shielding resin layer 13 by adhesive bonding or screw fastening. This embodiment directly uses the circuit board as the back panel of the neon light, which reduces production costs and saves more materials.
