The substrate element 20 has an electronic unit 233 , The PCIe bus 40 is on the substrate element 20 arranged and with the electronic unit 233 electrically connected. More precisely, the lighting area 30 is also with the PCIe bus 40 electrically connected. Of course, the lighting area can also be connected to eg the motherboard or another external power source. The electronic unit 233 may be a graphics processing module, display processing module, or other processing module, thereby providing the circuit module 1 can be used as a graphics card, display card or the like. The PCIe bus 40 can transmit both the power and the data.

The substrate element 20 has a substrate 23 and a first coat of paint 21 on. The substrate 23 has a translucent zone 230 and a first surface 231 , The first coat of paint 21 is on the first surface 231 and owns for the translucent zone 230 a light exit zone 210 , The light of the illuminated area 30 can through the light exit zone 210 from the circuit module 1 be broadcast. In the present embodiment, the substrate has 23 one of the first area 231 opposite second surface 232 , The substrate element 20 has a second lacquer layer 22 on, focusing on the second surface 232 located. The second coat of paint 22 owns for the translucent zone 230 a light entry zone 220 , The light of the illuminated area 30 can through the light entry zone 210 to the translucent zone 230 be blasted. The second lacquer layer and the light entry zone can also be omitted. Or the light of the illuminated area is irradiated through another zone of the substrate (not through the second area).

In the present embodiment, the first lacquer layer 21 and the second coat of paint 22 both formed from the insulating layer of the circuit. In the light entry zone 220 and light exit zone 210 the paint is removed. The light entry zone 220 and the light exit zone 210 may also be formed by a translucent layer. Specifically, the light exit zone 210 can be a translucent font (like trademark) that can be seen from the outside. Of course, the light entry zone may also be a font corresponding to the light exit zone.

More precisely, the lighting area 30 is at the substrate 20 arranged and is located next to the light entry zone 220 , The light area 30 can be a variety of light emitting diodes 31 include that around the light entry zone 220 of the substrate element 20 are arranged, whereby the light from the light exit zone 210 brighter and smoother. In another embodiment, the luminous area can not be arranged on the substrate element. The light of the illuminated area only has to be radiated directly or indirectly into the translucent zone.

The electronic device 100 indicates next to the circuit module 1 another case 50 on.

The housing 50 covers the two opposite sides of the circuit module 1 and at least the lighting area 30 starting to damage the eyes through the illuminated area 30 to avoid. The housing 50 points further according to the light exit zone 210 a translucent zone 51 on. The light from the light emission zone 210 can pass through the translucent zone 51 from the electronic device 100 be broadcast. The translucent zone 51 may be formed by an opening or a translucent layer.

Preferably, the housing has 50 according to the lighting area 30 a reflection structure 52 on. The reflection structure 52 reflects a part of the light of the illuminated area 30 on the translucent zone 230 , More specifically, the reflection structure 52 is an uneven structure, a plane surface is also possible, whereby the light is reflected irregularly and then evenly on the translucent zone 230 is blasted. In the present embodiment, the housing 50 a cooling housing (eg made of metal), to avoid overheating of the circuit module.

In summary, it should be noted that the electronic device and its circuit module does not require an additional light guide, wherein the light is radiated through the substrate and the transparent zone of the lacquer layer, whereby the thickness and the manufacturing costs are reduced.
