A low profile LED lamp bulb with high efficient heat dissipation is disclosed. Each of the lead frame unit has a top-down tapered metal section on bottom end adaptive for being bent inwards to form a lead frame bottom cup suitable for fitting in the low profile LED lamp. A modification embodiment is that a heat sink independent from electrode is attached to a backside of the lead frame with nonconductive adhesive material, heat and electricity are independent from with each other, so that no interference between heat and electricity, and heat can be dissipated mainly from the heat sink.

A low profile LED lamp with high efficient heat dissipation is disclosed. Each of the lead frame unit has a left top metal section, left middle metal section, right top metal section, and a top-down tapered metal section. The top-down tapered metal section is bent inwards to form a lead frame bottom cup which is suitable for fitting in the low profile LED lamp.

An air cooling LED lamp is disclosed. The lamp has air passages for natural air flow for cooling the lamp without using any electric fan to reduce electric energy consumption. The air passages still work for natural air cooling for the lamp when the lamp is configured either in a top down position or in a lateral position.

A light source device having a good heat dissipation capability is disclosed, in which heat generated by a light emitting device is conducted to a base fabricated by a porous material through a heat conducting mask or a heat conducting pipe. Due to a large area contact between the heat conducting mask or the heat conducting pipe and the base, the heat can be evenly conducted to the base, so that the base can absorb the heat and dissipate the heat to external, so as to improve a heat dissipation efficiency. Moreover, in the light source device of the disclosure, heat exchange of the light emitting device can be directly carried on through air convection, so that the heat generated by the light emitting device can be taken away from the light source device through heat exchange of cool air.
