Abstract
The utility model relates to an LED energy saving lamp bulb. A printing circuit board is provided with a step-down ballasting filter circuit; the other surface of the printing circuit board is relatively provided with an LED; the printing circuit board is fixed in a semi-spherical plastic casing; the surface which is provided with the LED is upward; a semi-spherical or an arc-shaped plane transparent lamp cover is fixedly connected with the semi-spherical plastic casing; a copper lamp head is arranged outside the casing. The LED energy saving lamp bulb with the structure can be applied to any occasion and has wide application range. Besides, because the LED is arranged in the semi-spherical plastic casing, the utility model can generate a light condensing effect to improve illuminance.
Description
The utility model relates to a kind of improvement of LED energy-saving lamp bubble structure.
China's ZL96229156 patent disclosure a kind of light emitting diode combined lamp holder, its structure is to be provided with a printed circuit board in the oblong plastic casing, the step-down ballasting circuit is installed on the printed circuit board (PCB), the edge of printed circuit board (PCB) is equipped with one group of light-emitting diode, one group of hole that matches with light-emitting diode is arranged at the edge of plastic casing equably, and light-emitting diode exposes outside housing by the hole on the plastic casing.Because the light-emitting diode of the combination lamp holder of this structure exposes outside housing, has just limited its scope of application, can only be applied in the lamp box, and light-emitting diode is arranged on the microscler printed circuit board (PCB), the light that sends is disperseed.
The purpose of this utility model provides a kind of LED energy-saving lamp bubble that improves structure.
The purpose of this utility model is to realize like this.The LED energy-saving lamp bubble includes printed circuit board (PCB) 2, light-emitting diode 3, lamp holder 5, and step-down ballast filter circuit is housed on the printed circuit board (PCB), at the corresponding printed circuit of the another side of printed circuit board (PCB) light-emitting diode is installed; Printed circuit board (PCB) is fixed in the hemisphere plastic casing 4, one of light-emitting diode is housed faces up; Hemisphere transparent lamp shade 1 or arc-plane transparent lamp shade 6 are fixedlyed connected with the hemisphere plastic casing, and the hemisphere plastic casing is provided with brass lamp holder 5 outward.
The LED energy-saving lamp bubble of this structure can be used in all case, and the scope of application is very wide, and because light-emitting diode is arranged in the hemisphere plastic casing, can produce the effect of optically focused, and illuminance is improved greatly.
The utility model is provided by following examples and accompanying drawing thereof.
1 transparent lamp shade, 2 printed circuit board (PCB)s, 3 light-emitting diodes, 4 hemisphere plastic casings, 5 brass lamp holders, 6 arc-plane transparent lamp shades.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is hemisphere transparent lamp shade structural representations.
Accompanying drawing 3 is hemisphere plastic casing structural representations.
Accompanying drawing 4 is to adopt arc-plane transparent lamp shade structural representation.
Accompanying drawing 5 is step-down ballast filter circuit figure.
Accompanying drawing 6 is printed circuit board arrangement schematic diagrames.
Accompanying drawing 7 is printed circuit board (PCB) another side structural representations.
Embodiment 1: see accompanying drawing 1.The LED energy-saving lamp bubble is equipped with step-down ballast filter circuit, the corresponding light-emitting diode 3 that is equipped with of the another side of printed circuit board (PCB) on the printed circuit board (PCB) 2; Printed circuit board (PCB) is fixed in the hemisphere plastic casing 4, one of light-emitting diode is housed faces up; Hemisphere transparent lamp shade 1 is fixedlyed connected with the hemisphere plastic casing, and the hemisphere plastic casing is provided with brass lamp holder 5 outward.
Embodiment 2: see accompanying drawing 4.Adopt arc-plane transparent lamp shade 6 structures.
Claims (1)
