The front panel of the box body is a transparent front panel, and the LED light-emitting glass component is vertically arranged in the box body with its front surface facing the transparent front panel;

[0007] The LED light-emitting glass component includes a front glass, a conductive film glass, a mirror glass, and a reflective film. The front glass, the conductive film glass, and the mirror glass are sequentially stacked from front to back and the edge parts are bonded and fixed by a frame-shaped glass strip. An LED light source array arranged in a matrix is connected to the front surface of the conductive film glass. The LED light source array is electrically connected to a switching power supply arranged on the box body. The reflective film is cut into a text shape or a pattern shape and then bonded to the front glass.

[0008] The box body includes an upper cover, a lower cover, a left side plate, a right side plate, a back plate, and a transparent front panel. The left side plate, the right side plate, the back plate, and the transparent front panel are mutually butted to form a closed rectangular frame and then connected between the upper cover and the lower cover. An upper component positioning strip and a lower component positioning strip are connected in the box body and between the left side plate and the right side plate. The top of the LED light-emitting glass component is clamped in the upper component positioning strip, and its bottom is clamped in the lower component positioning strip.

[0009] The LED light-emitting glass component further includes a rectangular outer frame. The stacked and bonded front glass, conductive film glass, and mirror glass are arranged in the rectangular outer frame and bonded and fixed to the inner wall of the rectangular outer frame.

[0010] A switching power supply, a light control switch, and a photosensitive probe with its photosensitive surface facing outside the box are provided on the described box body. The photosensitive probe is connected to the control end of the light control switch. The light control switch is electrically connected between the mains power and one end of the switching power supply, and the other end of the switching power supply is electrically connected to the LED light source array.

[0011] The upper cover, lower cover, left side plate, and right side plate of the described box body are welded and fixed. The transparent front panel is hermetically bonded and fixed to the upper cover, lower cover, left side plate, and right side plate respectively. The back panel of the box body is bolted to the upper cover, lower cover, left side plate, and right side plate respectively. Heat dissipation holes are provided on the back panel, and cable holes, positioning bolt holes, and drainage holes are provided on the lower cover.

[0012] The described transparent front panel is made of high-transparency acrylic board.

[0013] Advantages of the present utility model:

[0014] In the LED light-emitting glass component set by the present utility model, through the interaction between the reflection film in the shape of characters or patterns and the mirror glass, the characters or patterns present a 3D effect, which is very eye-catching both during the day and at night, with good publicity effect and aesthetic feeling, and can attract pedestrians to watch more.

[0015] The present utility model uses a high-transparency acrylic board as the transparent front panel, which is hermetically bonded and fixed to prevent dust and rain from entering the interior of the box body, and the overall light box is not easily damaged. Even if the LED light-emitting glass component inside is broken, it will not be exposed, avoiding potential safety hazards.

[0016] The switching power supply of the present utility model provides power supply for the LED light-emitting glass component. The light control switch is used to control the power supply of the switching power supply. The light control switch is electrically connected to the mains power, that is, only the light control switch is connected to the mains power, and the standby loss is far less than the standby loss of the switching power supply, which is relatively energy-saving.

[0017] The present utility model is provided with a photosensitive probe. When it gets dark, the light control switch is turned on to supply power to the switching power supply, and the LED light source array is powered on to work. When it gets bright, the light control switch disconnects the power supply of the switching power supply, and the LED light source array loses power and stops working, realizing the automatic lighting of the LED light box. While saving energy, it realizes the continuous eye-catching publicity effect of the LED light box. Description of the drawings
