Description

A kind of luminous LED bulb of full angle of good heat dissipation effect

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.

The circle diameter at support wire B outermost end place described above is less than the circle diameter at support wire A outermost end place.

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

Cell-shell described above is that afterbody is circular cell-shell or vertical pulling tail type cell-shell or oblique pull tail type cell-shell or candle type cell-shell.

The utility model vacuumizes by tracheae, after having vacuumized, then pyrocondensation closed port is nipped off in tracheae outside. The circuit board of constant-current source of the present utility model is placed in cell-shell, not only can reduce to take the intracavity space of screw thread socket, be mainly for each components and parts of constant-current source increase ceramic heat-dissipating seat, to make each components and parts radiating effect of constant-current source better, extended service life. The alternative existing incandescent lamp bulb of the utility model, and it is luminous to reach full angle, light extraction efficiency is high, good heat dissipation effect.
