Description

The LED bulb that a kind of full angle is luminous

Technical field

The utility model relates to the luminous LED bulb of a kind of full angle.

Background technology

Traditional incandescent lamp bulb power consumption is high, the life-span is short, under the overall situation of global resources anxiety, is forbidden selling gradually by national governments. LED bulb is the novel energy-conserving instrument of replace incandescent bubble, and LED is far superior to conventional incandescent bulb in the aspect of principle of luminosity, energy-conservation and environmental protection, replaces by LED illumination the trend that traditional incandescent lamp bulb will be whole illuminating industry development.

The granular LED of the general employing of illuminator of the LED light source in existing LED bulb. Because the LED power of individual particle shape is very little and brightness is limited, in order to ensure the brightness of LED bulb, LED light source is conventionally concentrated in together and forms with array format by multiple granular LED. It is large that multiple granular LED concentrate in together caloric value, must in LED bulb, heat abstractor be installed, and the material of heat abstractor is generally aluminium alloy, and cost is higher, weight is heavier. There is in addition directive property because LED light source self is luminous, even if the light sending is after the diffusion of diffusion shell, compared with conventional incandescent lamp source that can omnirange luminous intensity distribution, the luminous intensity distribution angle of existing LED bulb still seems very narrow, luminous intensity distribution angle is generally all below 120 °, light can not reach the back of lamp, can form shadow. At present, can accomplish that wide-angle light distributes although there are some LED bulb lamps, but used a large amount of optical elements such as reflector, lens, LED light efficiency is reduced, and for existing incandescent lamp bulb being substituted, need to greatly reduce heat abstractor, while causing LED work, temperature is high, 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.

In recent years, along with emerging in large numbers and the progress of semiconductor fabrication process of new material, there is the luminous LED lamp band of Liao Neng omnidirectional, can be luminous within the scope of 360 °, but how LED filament luminous Gai Zhong omnidirectional is installed in bulb, so that the luminous LED bulb replace incandescent bubble of Gai Zhong omnidirectional is the technical problem that will solve.

Utility model content

The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provide a kind of alternative existing incandescent lamp bulb, and it is luminous to reach full angle, and light extraction efficiency is high, simple in structure, the luminous LED bulb of full angle that volume is little.

For achieving the above object, technical solution of the present utility model is: the LED bulb that a kind of full angle is luminous, comprises screw thread socket, cell-shell, stem stem and one or more LED lamp band; The glass component that stem stem is integrated, its body is one end sealing, the other end has the bell-mouthed cylinder mating with cell-shell closure of openings; In cylinder, have the tracheae being connected as a single entity with body blind end, body blind end has the gas outlet being communicated with tracheae one end, the other end sealing of tracheae; Body blind end is fixed with at least two support wire; When LED lamp band is one, support wire is two, and LED lamp band one end conductive electrode is fixed therein in a support wire, and other end conductive electrode is fixed in another root support wire of prolongation; When LED lamp band is many, LED lamp band one end conductive electrode is fixed in each support wire, and the conductive electrode of the other end welds together, and each support wire connects and arranges according to the electrical connection of each LED lamp band; Each support wire other end connects the positive and negative output of constant-current source by wire, the positive and negative end of the positive and negative input connecting thread socket of constant-current source; Horn mouth one end of stem stem is fixed cell-shell head closure of openings and is fixed in screw thread socket with cell-shell head, between stem stem and cell-shell, forms cavity, after vacuumizing, is filled with heat transfer medium in cavity.

Support wire described above is nickel wire, wherein the other end of a support wire is welded on the copper wire of a plating magnesium, the other end of other support wire is welded on the copper wire of another root plating magnesium, and the copper wire of plating magnesium is connected on the positive and negative output of constant-current source again. Nickel wire conducts electricity very well, softness, and good toughness, can 180 ° of bendings, and the copper wire of plating magnesium is saved copper, reduces production costs.

Heat transfer medium described above is the mixture of helium or hydrogen or helium and hydrogen.

The afterbody of cell-shell described above is circle or vertical pulling tail type or oblique pull tail type.

The utility model vacuumizes by tracheae, after having vacuumized, then pyrocondensation closed port is nipped off in tracheae outside. The utility model has been saved stem stem, and the conductive electrode of LED is directly welded together, and its volume is little, simple in structure, and the bulb that is applicable to smaller power uses. The alternative existing incandescent lamp bulb of the utility model, and it is luminous to reach full angle, light extraction efficiency is high.
