When the light source assembly 170 further includes a third light source 173 and/or a fourth light source 174, the plurality of third light sources 173 and/or the plurality of fourth light sources 174 electrically connected to the conductive row 124 of each conductive group 121 are also distributed in a central symmetry. Therefore, the light sources of the respective colors of the lamp body 100 are distributed in a central symmetry manner, the light emitted by the light sources of the lamp body 100 is more uniformly mixed, and the light supplementing effect of the lamp body 100 is further improved.

In other embodiments, the plurality of first light sources 171 and the plurality of second light sources 172 electrically connected to the conductive rows 124 of at least two conductive sets 121 are symmetrical to each other.

In some embodiments, as shown in fig. 6 to 8, the second plate surface 112 of the substrate 110 is provided with a third heat sink portion 143, and the third heat sink portion 143 is used for dissipating heat of the substrate 110. The lamp body 100 further includes a heat sink 160, a plate surface of the heat sink 160 is disposed opposite to the second plate surface 112, and the plate surface of the heat sink 160 is connected to the third heat sink 143.

Alternatively, the height of the insulating layer 151 with respect to the second plate surface 112 may be smaller than or equal to the height of the third heat dissipation portion 143 with respect to the second plate surface 112, so as to ensure that the third heat dissipation portion 143 can be kept connected to the plate surface of the heat dissipation plate 160, and to ensure the heat dissipation effect of the third heat dissipation portion 143 and the heat dissipation plate 160.

In some embodiments, the conductive traces 120 may further include a temperature sensor disposed on the first board surface 111 or the second board surface 112 of the substrate 110. The temperature sensor can detect the temperature of the lamp body, and when the temperature of the lamp body is too high, the operation such as alarming and circuit breaking can be carried out, so that the service life of the lamp body is prolonged. The temperature sensor may be a thermistor or other sensor capable of detecting temperature, and is not limited herein.

In some embodiments, the substrate 110 may be a substrate with a good thermal conductivity, such as an aluminum nitride ceramic substrate and/or an aluminum oxide ceramic substrate, and is not limited herein. Solder resists may be disposed on the first board surface 111 and/or the second board surface 112 of the substrate 110 to facilitate the soldering between the light sources of the light source assembly 170 and the conductive portions.
