Abstract
The utility model is applicable to the technical field of lighting and provides an LED lamp bulb. The LED lamp bulb comprises a lamp holder, a lampshade, an LED lamp filament arranged inside the lampshade and a power supply driving module for converting alternating current into direct current, wherein the LED lamp filament is electrically connected with the power supply driving module and comprises a substrate and a plurality of LED chips arranged on the substrate. The LED lamp bulb does not need a heat radiating body, accordingly the lampshade can wrap the LED lamp filament at a wide angle, and a light-emitting angle of the LED lamp bulb can reach to 360 degrees. In addition, compared with incandescent lamps, the lamp bulb is a light-emitting light source, saves energy and is environment-friendly and long in service life.
Description

Technical problem to be solved in the utility model is to provide a kind of LED bulb, is intended to solve the problem that LED bulb volume of the prior art is large, lighting angle is little.
The utility model is to realize like this, a kind of LED bulb, comprise lamp holder, lampshade and alternating current is converted to galvanic electric power driving module, described LED bulb also comprises the LED filament that is arranged at described lampshade inside, described LED filament comprises substrate and is arranged at the some LED chips on substrate, and described LED filament is electrically connected with described electric power driving module.
Further, the length in described LED filament light-emitting region is 24～26mm.
Further, the entire length of described LED filament is 38～42mm.
Further, described lampshade inside is provided with a projection, in described projection, extends insulated column, and the two ends of described insulated column laterally extend respectively conductive rod, and the two ends of described LED filament are electrically connected with the conductive rod at described insulated column two ends respectively.
Further, described LED bulb comprises the LED filament described in many, the electrical connection parallel with one another of described LED filament.
Further, described LED bulb comprises four LED filaments parallel with one another, and the LED filament described in each comprises 25～27 LEDs chips.
Further, described driving power module is arranged at described lamp holder inside.
Further, the glass that described insulated column is printing opacity.
Further, the glass that described projection is printing opacity.
Further, in described lampshade, be filled with argon gas.
The utility model compared with prior art, beneficial effect is: bulb of the present utility model is without radiator is installed, thereby lampshade can be with wider angle parcel LED filament, make the lighting angle of LED bulb can reach 360 °, in addition, compared to incandescent lamp, it is illuminating source that LED bulb of the present utility model adopts LED filament, and energy-saving and environmental protection more, life-span are long.
