Illumination apparatus with heat dissipating tubes

摘要

An illumination apparatus (10) comprises a housing (12), a LED base (14), and a heat sink (16), the housing (12) having a light emitting surface (122) and a heat dissipation surface (124) opposite to the light emitting surface (122), the LED (14) base including a circuit board (142) and a plurality of LED chips (144), the heat dissipation surface (124) adjacent to the circuit board (142), the light emitting surface (122) of the LED chips (144) toward the light emitting surface (122) of the housing (12), and the heat sink (16) including a plurality of heat dissipating tubes (162). The heat dissipating tubes (162) are interlaced on the heat sink (16) and the heights of the heat dissipating tube (162) are different.
