As preferred version of the present utility model, described ceramic lamp surface is outward extended with some radiating fins, the bottom of mounting platform described in described radiating fin tip contact.
As preferred version of the present utility model, the outside extension width of described radiating fin connects one end decrescence by the one end that connects with mounting platform to lamp holder, forms open air groove between two between radiating fin.
Above-mentioned heat radiation fin structure is except increase area of dissipation, and the free-air groove formed between radiating fin between two makes the heat of ceramic lamp body outwardly can shed with convection type, reaches to better radiating effect.
As preferred version of the present utility model, described boss, ceramic lamp body and radiating fin are nine-five aluminium oxide ceramic one-shot forming, and the inner space of described boss inside and ceramic lamp body, boss offers the through hole passed through for lamp circuit board electric wire.
As preferred version of the present utility model, described ceramic lamp body bottom is provided with the threaded portion be connected with described lamp holder.
Remarkable gonosome of the present utility model is present: adopt many fins pottery lamp body, have high heat conduction and high insulating property, meet the requirement of LEDbulb lamp heat dispersion and insulating properties, ensure life-span and the use safety of LEDbulb lamp better; The three-dimensional LED lamp bead matrix of taper, makes the lighting angle of LEDbulb lamp reach 300 degree, and has booster action to the illumination in region immediately below LEDbulb lamp. thus reach better light source utilization and illuminating effect.The utility model has energy-saving and environmental protection and effectively solves the problem of the aspects such as prior art central heat radiation, insulation, light output angle, no matter from economy, or practicality, the utility model is all the products with excellent performance, is worth of widely use.
