In the figure; a skin panel 100; a lamp assembly 200; a connecting assembly 300; a body 400; a light emitting source 500; a light-shielding paint layer 600; a light-transmitting region 601; an obscured region 602; a light-transmissive primer layer 700; a light transmissive colored paint layer 800; the transparent varnish layer 900 is protected.

As shown in fig. 2, the light-emitting bumper is installed in an automobile for use, wherein the light-emitting bumper includes a skin panel 100 and a lamp assembly 200, a connection assembly 300 is provided between the skin panel 100 and the lamp assembly 200, the skin panel 100 and the lamp assembly 200 can be detachably and integrally connected to each other through the connection assembly 300, and the skin panel 100 and the lamp assembly 200 are connected through the connection assembly 300, so that the bumper is not directly damaged by the lamp assembly 200 when being impacted, the maintenance cost of the automobile is reduced, the service life of the lamp assembly 200 is prolonged, and in addition, the connection between the skin panel 100 and the lamp assembly 200 is realized through the connection assembly 300, thereby improving the assembly efficiency of the light-emitting bumper, reducing the labor intensity, and improving the yield of the light-emitting bumper.

Because it needs to emit light, in order to ensure the overall aesthetic property when emitting light and not emitting light, the skin panel 100 is mainly used here, as shown in fig. 1, the skin panel 100 includes a main body 400, in this embodiment, the main body 400 is made of a light-transmitting PP material, the light transmittance of the main body 400 is 60% -80%, so that the light transmittance of the whole light-emitting bumper is better, here, a light-emitting source 500 is arranged behind the main body 400, wherein the light-emitting source 500 can be a light or an LED lamp, etc., the main body 400 has an inner surface and an outer surface, and a light-shielding layer is provided on the outer surface, the light-shielding layer includes a shielding region 602 and a light-transmitting region 601, wherein the shielding region 602 mainly serves to shield the non-light-emitting position, the light-transmitting region 601 mainly serves to transmit the light emitted by the light-emitting source 500, the light emitted by the light-transmitting region 601 can pass through as a further optimization, and the light-transmitting region 601 of the light-shielding layer is formed by engraving the light-shielding layer, Corrode the light shield layer, carry out mechanical scraping, heat or form to the screen printing to the light shield layer.

Here the light shield layer is shading paint layer 600 in this embodiment, at least one deck printing opacity priming paint layer 700 has between shading paint layer 600 and the body 400 surface, for making whole luminous bumper present pleasing to the eye colour, the colourful layer has on the surface of light shield layer, the colourful layer is for arranging at least one deck printing opacity priming paint layer 800 on the surface of light shield layer, shading paint layer 600 forms between the surface of printing opacity priming paint layer 700 and printing opacity priming paint layer 800, under the condition of not luminous in order to guarantee skin panel 100, skin panel 100's colour and the holistic colour of car match, set up printing opacity priming paint layer 800, improve the japanning reliability, avoid taking place the paint automatic to drop, consequently, need set up a printing opacity priming paint layer 700 earlier before setting up printing opacity paint layer on body 400, with this adhesion force that improves printing opacity paint layer.

In this embodiment, after the light-shielding paint layer 600 is completely sprayed, even if the whole main body is still in the "opaque" state under the irradiation of the light-emitting source 500, at this time, the light-transmitting region 601 needs to be formed by performing laser etching on the light-shielding paint layer 600, corroding the light-shielding paint layer 600, mechanically scraping the light-shielding layer, heating the light-shielding layer or performing screen printing on the light-shielding layer, so that the light-transmitting region 601 can emit light under the irradiation of the light-emitting source 500, while the region not processed is still shielded by the light-shielding paint layer 600, therefore, the region is still in the "opaque" state, so that the main body in this state can form a light-emitting region under the irradiation of the light-emitting source 500, the region not emitting light does not emit light, at least one layer of protective transparent clear paint layer 900 is provided on the outer surface of the light-transmitting paint layer 800 to prevent the light-transmitting paint layer 800 from fading or color difference due to long-time environmental changes, thereby extending the useful life of the clear lacquer layer 800

Therefore, when the light source 500 is turned off, the body 400 has the first color presented by the colored layer, when the light source 500 lights, the body 400 presents the second color different from the first color after the light passes through the colored layer from the light transmitting area 601, here, the light transmittance of the light transmitting colored paint layer 800 is between 10% and 40%, the light transmitting colored paint layer 800 has the color, so that the first color of the light transmitting colored paint layer 800 is presented when the light source 500 is not lighted, and the second color is presented after the light and the light transmitting colored paint layer 800 are mixed when the light source 500 lights, so that the uniformity of the lighting of the skin panel 100 is improved, in addition, when the skin panel 100 is not lighted, the paint color of the skin panel 100 is the same as that of the whole vehicle, so that the generation of color difference is avoided, and the attractiveness of the whole vehicle is improved.
