[0022] Example: see image 3 , Figure 4 or Figure 5 , A heat dissipation method for an array LED light source panel. A number of LEDs are provided on the light source panel 1 to form an LED ring with two or more arrays along the center and outwards. The heat dissipation panel 1 is provided between the adjacent inner and outer LED rings. In the matched heat insulation groove 3, each LED and the corresponding heat insulation groove form a heat dissipation channel so that heat can be quickly transferred to the back of the panel. The light source panel 1 is a printed board such as an aluminum substrate with a circular shape as a whole. image 3 , The LEDs on it are distributed in a circular array with the center of the substrate mounting hole as the center, the heat insulation grooves between adjacent LED rings are arranged at the above center, and the corresponding heat dissipation area of each LED is the same. The light source panel 1 may also be a printed board such as an alu...
