The marking structure includes a bottom layer and a marking layer, and the bottom layer and the panel of the marking structure are fixed by hot melting. The bottom layer of the marking structure has a certain thickness and includes post holes, and the marking layer protrudes from the bottom layer. There is a gap between the post hole and the identification layer. The lamp holder includes a hole structure, and the thickness of the light guide sheet decreases continuously from one end close to the LED lamp. The light guide sheet is made of polymethyl methacrylate and ABS plastic, and the surface layer of the light guide sheet is coated with There is a semi-transparent bronzing film. The lamp holder is fixed on the hardware front plate in the form of buckles, and the lamp holder and the LED lamp are connected together and arranged on the thicker side of the light guide sheet.

The beneficial effect of the utility model is: by using ABS and PMMA two-color injection molding technology, the light emitted from the LED lamp is evenly distributed on the light guide sheet, and the light leakage is reduced, and the demoulding slope of the light guide sheet also matches the radian of the signboard , The design is beautiful, the logo structure and the panel are fixed by hot melting, the structure is more compact, the use is more durable, and it will not fall off. Secondly, use the LED light to sneak into the "light guide sheet", that is, make a hole structure on the LED side of the "light guide sheet", and match the LED with the hole, so as to achieve the convergence of light sources, reduce the loss of light energy, use side light incident, and the structure is convenient , only need a simple LED light to achieve the effect.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Figures 1 to 3 schematically show one of the implementations of the present invention.

The luminous sign includes a panel 1, a sign structure 2, a light guide sheet 3, a fixed cover 4, a lamp holder 5 and a printed circuit board 6, wherein the panel 1 includes a pillar 7, and the sign structure 2 is provided with a post hole 8. The panel 1 and the logo structure 2 are fixedly connected, and the pillar holes 8 are engaged with the pillars 7, the light guide sheet 3 is engaged in the fixed cover 4, and the mouth of the fixed cover 4 is connected with the sign structure 2 The reverse side is fixedly arranged, the printed circuit board 6 includes an LED lamp 9, a light-emitting circuit and a first buckle, the lamp holder 5 includes a hole structure 10, a fixing hole and a second buckle, the lamp holder 5 and a printed circuit The plates 6 snap together and are fixed by the fixing holes.

The panel 1 includes a screw seat, the fixing cover 4 includes screw holes, the screw holes correspond to the position of the screw seat, and each group of corresponding screw holes is connected to the screw seat by screws. In this way, the fixed cover 4, the sign structure 2 and the panel 1 can be tightly fixed. The sign structure 2 includes a bottom layer 11 and a sign layer 12, and the bottom layer 11 of the sign structure 2 is fixed to the panel 1 by means of heat fusion. The bottom layer 11 of the marking structure 2 has a certain thickness and includes post holes 8 , and the marking layer 12 protrudes from the bottom layer 11 . During installation, it is only necessary to interlock the panel 1 with the sign structure 2 so that the protruding part of the sign structure 2 exposes the panel 1 . Secondly, since there is a certain gap between the post hole 8 and the marking layer 12, the post hole can be engaged with the post, and the above-mentioned hot melting method is added to make it more stable. The lamp holder 5 includes a hole structure 10 capable of accommodating the LED lamp 9 . The LED lamp will be inserted into the hole structure 10 inside. The thickness of the light guide sheet 3 decreases continuously from one end close to the LED lamp 9 to the other end, and the LED lamp 9 receives light from the thicker side during operation. The light guide sheet 3 is made of polymethyl methacrylate and ABS plastic, and the surface layer of the light guide sheet 3 is coated with a semi-transparent bronzing film. The lamp holder 5 is fixed on the hardware front plate in the form of buckles, and the lamp holder 5 and the LED lamp 9 are connected together and arranged on the thicker side of the light guide sheet 3 . When working, the side-incident light passes through the light guide sheet 3, and the light is reflected inside and then emitted from the light-emitting surface. Since the inside is injected with ABS plastic, it is not easy to produce light spots, and the design can effectively prevent light leakage and ensure brightness.

The above embodiments are only intended to illustrate rather than limit the utility model, so all equivalent changes or modifications made according to the method described in the scope of the patent application of the utility model are included in the scope of the patent application of the utility model.
