Description

Technical Field

[0001] The utility model relates to the field of light display components, in particular to a high-brightness backlight plate. Background Art

[0002] In the prior art, the LED lamps of the vehicle backlight are usually arranged on the side, but the area of ​​the side is small and the number of lamp beads that can be arranged is small, resulting in dim brightness and failing to meet the requirements of some devices that require higher brightness.

[0003] Therefore, there is an urgent need to provide a high-brightness backlight panel. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a high-brightness backlight panel.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A high brightness backlight panel for illuminating a display component comprises: a substrate and a light source component; the substrate comprises a first side surface and a second side surface opposite to each other, the first side surface faces the display component to be illuminated, and the light source component is arranged on the first side surface.

[0007] In one embodiment, the light source assembly is a plurality of LED lamps, and the LED lamps are arranged at equal intervals on the first side surface.

[0008] In one embodiment, the substrate is an aluminum alloy plate.

[0009] In one embodiment, a heat dissipation component is disposed on the second side surface.

[0010] In one embodiment, the heat dissipation component is a graphite sheet.

[0011] In one embodiment, the heat dissipation component is an aluminum alloy heat dissipation element, and the aluminum alloy heat dissipation element is provided with multiple heat dissipation blades.

[0012] In one embodiment, the aluminum alloy heat sink is screwed to the aluminum alloy plate.

[0016] Compared with the prior art, the utility model has at least the following advantages:

[0017] 1. The high-brightness backlight panel of the utility model is arranged on the first side of the substrate. Compared with the prior art, the light source assembly is arranged on the side of the substrate. Because the surface area of ​​the first side is larger than the surface area of ​​the side of the substrate, the number of LED lamps that can be arranged on the side is relatively small. However, the present application can arrange more lamp beads on the first side of the substrate, and the brightness is stronger, which can meet the application environment with higher working requirements, thereby improving the user experience.

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0025] The present application embodiment provides a high brightness backlight panel, please refer to Figure 1 and Figure 2, including a substrate 10 and a light source assembly 20, the substrate 10 includes a first side A and a second side B, the first side A faces the display assembly to be illuminated, and the light source assembly 20 is arranged on the first side A. Compared with the prior art that the light source assembly 20 is arranged on the side of the substrate 10, because the surface area of ​​the first side A is larger than the side surface area of ​​the substrate 10, the number of LED lamps that can be arranged on the side is relatively small, while the present application can arrange more lamp beads on the first side A of the substrate 10, and the brightness is stronger, which can meet the application environment with higher working requirements, thereby improving the user experience.

[0026] For further information, see Figure 2 The light source assembly 20 is a plurality of LED lamps, and the LED lamps are arranged at equal intervals on the first side surface A of the substrate 10. For example, the LED lamps are arranged in five rows and four columns on the first side surface A to evenly illuminate the display assembly, which greatly improves the lighting brightness compared to one row in the prior art.

[0027] Further, see Figure 1 and Figure 3 Since the LED lamp generates a lot of heat when it is working, the substrate 10 is set to an aluminum alloy plate. The aluminum alloy plate is made of aluminum alloy metal material and has a strong heat dissipation capacity, thereby dissipating the heat generated by the LED lamp to the outside, thereby protecting the working performance of the LED lamp and extending the service life of the LED lamp.

[0028] In order to further enhance the heat dissipation effect, a heat dissipation component 30 is set on the second side B of the aluminum alloy plate. The heat dissipation component 30 has good heat dissipation performance to quickly transfer the heat generated by the LED lamp to the aluminum alloy plate and the heat dissipation component 30, so that the aluminum alloy plate and the heat dissipation component 30 quickly dissipate heat.

[0029] In one embodiment, the heat dissipation component 30 is a graphite sheet, which has a large effective surface area for heat dissipation and can be smoothly attached to the second side surface B.

[0030] In another embodiment, the heat dissipation assembly 30 is an aluminum alloy heat sink, which is provided with multiple heat dissipation blades, and the heat dissipation blades are perpendicular to the second side surface B. Because the aluminum alloy heat sink is made of aluminum alloy material, it is resistant to high temperature and has good thermal conductivity. The heat generated by the LED lamp is quickly taken away by the aluminum alloy plate and the aluminum alloy heat sink to maintain a lower temperature working environment for the LED lamp to operate.

[0031] For further information, see Figure 3The aluminum alloy heat sink is screwed to the aluminum alloy plate, so that the aluminum alloy heat sink and the aluminum alloy plate can quickly conduct heat and dissipate it in the air, and the screwing fixation method makes the connection between the two more stable and easy to disassemble. Specifically, the embodiment of the present application also includes four high-temperature resistant screws 50, and four corresponding screw holes are respectively opened on the aluminum alloy plate and the aluminum alloy heat sink. The aluminum alloy plate and the aluminum alloy heat sink are screwed together through the four screws 50 and the four corresponding screw holes.

[0032] Furthermore, a thermal grease layer is provided on the aluminum alloy heat sink, and the thermal grease layer is made of a thermal grease heat dissipation material to further enhance the heat dissipation effect.

[0033] Also, see Figure 3 A circuit board positioning area 40 is provided on the second side surface B of the aluminum alloy plate, and the heat dissipation component 30 is arranged to avoid the circuit board positioning area 40 to facilitate the arrangement of the circuit board.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
