As shown in FIG. 1 , the conductors include at least one high potential main conductor 552 , at least one high potential subconductor 553 , at least one low potential main conductor 555 , and at least one low potential subconductor 554 . The electrode portion includes at least a pair of electrode portions E1 and E2. In this embodiment, the diameter of the high potential main wire 552 is larger than the diameter of the high potential sub wire 553, and the diameter of the low potential main wire 555 is larger than the diameter of the low potential sub wire 554.

As shown in Figures 1 to 2, the light guide plate LGP is arranged opposite to the circuit layer 550, where the light guide plate LGP includes a plurality of microstructures MS to guide light. The light source LED is coupled to at least a pair of electrode parts (for example, electrode parts E1 and E2) located within the key projection OP range. The high-potential sub-conductor 553 is electrically connected between the high-potential main conductor 552 and the light source LED, and the low-potential sub-conductor 554 is electrically connected between the low-potential main conductor 555 and the light source LED.

The microstructure MS can be realized by a plurality of scattering dots composed of high reflectivity ink (such as white paint), or a plurality of concave and convex optical microdot structures formed on the lower surface of the light guide plate LGP.

As shown in FIG. 1 , the orthographic projection of the microstructure MS of the light guide plate LGP does not overlap with the high potential main wire 552 and the low potential main wire 555 passing through at least one key projection OP. In this way, the illumination light guided through the microstructure MS will not be blocked by the high potential main wire 552 or the low potential main wire 555 . Compared with the comparative example in which the orthographic projection of the microstructure in the light source lamp panel overlaps with the high potential main wire or the low potential main wire projected through at least one button, due to the orthographic projection of the microstructure MS in the light source lamp panel 10 of the present invention Not overlapping the high-potential main wire 552 or the low-potential main wire 555 that passes through at least one key projection OP can avoid the lighting light being blocked by the high-potential main wire 552 or the low-potential main wire 555, so the light extraction efficiency can be improved, thereby having Better optical effects.

In some embodiments, the area of the orthographic projection of the light-transmitting hole SUPH that does not overlap the high-potential main wire 552 or the low-potential main wire 555 is larger than the area of the orthographic projection of the light-transmitting hole SUPH that overlaps the high-potential main wire 552 or the low-potential main wire 555 . That is, you can try to make the area where the orthographic projection of the base plate SUP overlaps the high-potential main wire 552 or the low-potential main wire 555 larger, and reduce the overlap of the orthographic projection of the light-transmitting hole SUPH on the high-potential main wire 552 or the low-potential main wire 552. The area of the main wire 555 makes it less likely that the high potential main wire 552 or the low potential main wire 555 blocks light. In some embodiments, the orthographic projection of the light-transmitting hole SUPH of the base plate SUP does not overlap with the high-potential main wire 552 or the low-potential main wire 555 passing through the key projection OP, so as to achieve better optical effects.

The reflective layer RL and light-shielding layer ML in various embodiments of the present invention can be realized by independent high-reflectivity sheets and opaque (low-transmittance) sheets, respectively. However, the reflective layer RL and the light-shielding layer ML can also be realized by high-reflectivity ink (such as white or silver ink) and opaque ink (such as black ink) respectively, and are selectively printed on the lower surface of the base plate SUP and the protective layer PL. The upper or lower surface, or even directly printed on the upper or lower surface of the light guide plate LGP, provides reflection and light-shielding functions.

As shown in FIG. 2 , the light source panel 100A further includes a reflective layer RL. The orthographic projection of the reflective layer RL overlaps the microstructure MS, and the reflective layer RL is disposed between the microstructure MS and the substrate 541 .

The light-emitting surface of the light source LED faces downward. The light shielding layer ML and the protective layer PL are disposed on different sides of the light guide plate LGP. For example, the light shielding layer ML is disposed on the side (ie, the upper side) of the light guide plate LGP that is closer to the key KC, and is disposed on the substrate 541 . The light-shielding layer ML and the circuit layer 550 are respectively disposed on opposite sides of the substrate 541. The protective layer PL is disposed on the side (ie, the lower side) of the light guide plate LGP that is farther away from the key KC. Since the light source LED in Figure 3 shines downward, the protective layer PL can be directly made of reflective material. Alternatively, a reflective layer RL can be provided on the upper or lower surface of the transparent protective layer PL, or the reflective layer RL and the light-shielding layer ML can be stacked so that the reflective layer RL is close to the light guide plate LGP, so that the light source LED directly and indirectly from the light guide plate The light from LGP is reflected back to the light guide plate LGP.
