Abstract:
1. A heat dissipating structure associated with light emitting diodes comprising: a rectangular circuit substrate with a first facial side providing at least a light emitting diode and a bottom side providing an elongated lower semicircular groove between two opposite long lateral sides of said bottom side, wherein said upper semicircular groove extends along and parallels to said long lateral sides; a base having a shape the same as said circuit substrate with a second facial side providing an elongated upper semicircular groove between two opposite long lateral sides of said second facial side corresponding to said lower semicircular groove such that said base is joined to said substrate in such a way that said upper semicircular groove and said lower semicircular groove form an elongated circular receiving space; a guide heat pipe with a first end and a second end having a first pipe section, which includes said first end and a second pipe section, which includes said second end, wherein said first section is disposed in said circular receiving space; a heat dissipating device with a plurality of fins being pierced with said second pipe section; a casing to accommodate said circuit substrate with said base, said guide heat pipe and said heat dissipating device; wherein said casing provides a partition disposed along the middle of the depth thereof, said partition has a first surface for being attached with said base, a second surface for being disposed with said heat dissipating device and a through hole for being pierced with said guide heat pipe.
