Abstract
The utility model discloses an LED bead which comprises an LED chip and an aluminum substrate. The LED chip is fixed on the aluminum substrate, and two electric conduction lamp pins in the LED chip extend out of the aluminum substrate through insulation materials in the aluminum substrate. The aluminum substrate is provided with at least one LED chip installation face and at least one heat dissipation face, the heat dissipation face is provided with heat dissipation holes which are communicated completely and evenly formed in the aluminum substrate, and any heat dissipation hole is communicated with at least one adjacent heat dissipation hole. According to the LED bead, the heat dissipation face is provided with the heat dissipation holes which are communicated completely and evenly formed in the aluminum substrate and any heat dissipation hole is communicated with at least one adjacent heat dissipation hole, therefore, cold air and hot air ventilation of connection portions of the two holes are enhanced under the condition that the heat dissipation area is not enlarged, air ventilation is conducted to heat dissipation components, meanwhile, two adjacent heat dissipation holes are communicated to form a crossed connection-hole structure, and therefore the purpose of enlarging the heat dissipation area is achieved. Thus, heat dissipation efficiency is improved, temperatures of the whole LED are effectively reduced, and normal work of high-power LED products is guaranteed.
