Description
Technical field
The utility model relates to field of LED illumination, particularly relates to a kind of 360 degree of LED bulb.
Background technology
As everyone knows, the epoch-making significance brought to the mankind of Edison invented incandescent lamp.Traditional incandescent lighting has inveteracy status to the mankind, but since entering new 21 century, due to the appearance of environmental protection more, energy-conservation LED light source new technology, has made people have to gradually abandon using conventional incandescent tengsten lamp.But the LED bulb on existing market is solid-state illumination one side luminous characteristics because of it, the overwhelming majority is luminous lower than 180 low-angles.At present, although there are some LEDbulb lamp can accomplish wide-angle Light distribation, the optical elements such as a large amount of reflectors, lens are employed, the diffusing globe cell-shell that device is larger.But be make LED light imitate to reduce by this kind of mode one, two is make LED bulb need to greatly reduce heat-dissipating space when maintaining and substituting form, thus when making LED work, temperature remains high, and LED power cannot be done greatly.Meanwhile, existing large-angle LED bulb lamp all needs to use diffusion shell to carry out astigmatism, and illuminating effect and traditional incandescent lamp also have larger gap.
Therefore, LED can not replace conventional incandescent completely.Its wide-angle of traditional incandescent lamp is luminous, the feature of three-dimensional illumination and the promotion of prevailing custom of missing old times or old friends, and it is potential huge market still.Now also there is the LED pompon bubble technology of similar imitative conventional incandescent both at home and abroad successively.Such as adopt transparent glass or pottery as the bearing substrate of LED chip, then carry out light-source encapsulation, then continue to use the equipment and process of conventional incandescent to carry out.Although this kind of its process stabilizing of scheme is reliable, the heat radiation of LED light source but can not get good solution.This is because have employed thermal conductivity factor is not that very high glass ceramic baseplate is as conductor, even if be filled with inert gas at bulb, strengthen convection current, extend the life-span, but LED light source still can not get good heat radiation, thus have a strong impact on the service life of LED bulb.Further, the encapsulation of this kind of scheme, assemble its technique also more complicated, production cost is higher.
Chinese patent CN 103712106A is separately had to disclose the all-round smooth LED bulb of a kind of wide-angle.This invention utilizes the gas of low viscosity, high thermal conductivity to fill to dispel the heat, simultaneously by utilizing the LED strip shape filament light sources of comprehensive bright dipping, and reasonably optimize its spatial arrangement in the bulb, thus obtain all-round optical illumination and desirable LED bulb of dispelling the heat.Although this invention can obtain larger beam angle but its structure is still comparatively complicated, wherein, the fixing needs of bar shaped filament relies on the stem stem being arranged on bulb.And stem stem is generally ceramic material, easily crisp, easily increase the scrappage of product; And due to its fragility, stem stem installs also very inconvenient.Meanwhile, bar-shaped LED omnidirectional filament and the conduction of extraneous power supply are connected needs first, second connect wire, and this adds the quantity of bulb solder joint undoubtedly, makes assembling product complex procedures, is unfavorable for the quick assembling realizing product.In addition; this invention is by filling the mist of hydrogen and helium as heat radiation protection gas; although the heaviness of eliminating and the radiator be in the light again; but the heat transference efficiency of gas is fast not as good as the efficiency of conducting heat between solid all the time; therefore; dispel the heat with the mist of hydrogen and helium, its radiating efficiency is unsatisfactory.
