The specific embodiment
Fig. 1 is the three-dimensional exploded view of first embodiment of the invention wide-angle light emitting LED lamp 100, and this wide-angle light emitting LED lamp 100 comprises a bulb housing 10, light source board 20, radiating piece 30, drive 40 and body 50.This radiating piece 30 is arranged on this body 50 tops, and this light source board 20 is arranged on the top of this radiating piece 30, and on this light source board 20, interval arranges a plurality of LED light sources 21, in the top that this bulb housing 10 is located at this radiating piece 30 is contained in this light source board 20.This radiating piece 30 is provided with 31 bottoms around these LED light sources 21,31，Gai transmittance section, transmittance section and arranges.
Please refer to Fig. 1, this radiating piece 30 also comprises the cup 32 that conducts heat, and this heat transfer cup 32 is made by the thermal coefficient of expansion alloy material close with this transmittance section 31.The middle part of this transmittance section 31 forms accepting hole 312, and it is interior and thermally coupled with this light source board 20 that this heat transfer cup 32 is housed in this accepting hole 312.This transmittance section 31 comprises a plurality of spaced fins 311, each fin 311 lay respectively at these LED light sources 21 under, these fins 311 are one-body molded by identical material with this transmittance section 31.This transmittance section 31 is by the injection mo(u)lding of Merlon mixing glass.The material of this bulb housing 10 is identical with the transmittance section 31 of this radiating piece 30, and this bulb housing 10 is thermally coupled by heat-conducting glue and this radiating piece 30.
Please refer to Fig. 1, this light source board 20 is made by transparent or semitransparent material, for example glass or ceramic material.End face integral packaging that these LED light sources 21 are arranged in this light source board 20 in the form of a ring form annular encapsulated layer (not shown), and this encapsulated layer is provided with fluorescent material (not shown).
Please refer to Fig. 3, this radiating piece 30 and these bulb housing 10 link positions and this radiating piece 30 and these body 50 link positions are equipped with the blind hole 33 of full communication between the higher and lower levels, and these blind holes are separately positioned on top and the bottom of each fin 311 hypotenuse.
