Embodiment Construction
[0019] The invention relates to a novel radiator for LED lamps, which is used to solve the problem of insufficient heat dissipation of existing high-power LED lamps. Such as Figure 1-3 As shown, an aluminum-based circuit board 1 is also fixed on the bottom surface of the radiator, and the aluminum-based circuit board 1 is provided with LED lamps 2 arranged in an array. In addition, on the outside of the aluminum-based circuit board 1 of the LED lamp A lampshade 3 for protecting the LED lamp can also be provided. The technical improvement made in the present invention is that the heat sink is composed of a heat sink substrate 4 and a main heat dissipation fin 5 fixed on the heat dissipation substrate. As for the sheet 6, in the process of actual use, if the heat dissipation effect is to be further improved, some ribs can be added on the auxiliary heat dissipation sheet 6 for heat dissipation. The main cooling fins 5 are arranged in an array and fixed on the radiator substrat...
