Embodiment Construction

[0026] Combine below Figure 1 to Figure 3 , the present invention is further described:

[0027] Such as figure 1 As shown, an LED light bulb that can be directly connected to AC power includes a spherical light-transmitting layer 110, a cylindrical reflective layer 120, a plurality of LED chips 140, a circuit board 150, a plug 130 and a lamp holder 170, and a plurality of LED chips 14 is arranged at the junction of the spherical transparent layer 110 and the cylindrical reflective layer 120, and the cone angle A formed by the center of the spherical transparent layer 110 and the junction of the spherical transparent layer 110 and the cylindrical reflective layer 120 is 120°. According to the principle of light reflection, the columnar reflective layer 120 can reflect the light emitted by the LED chip to the upper spherical transparent layer as much as possible, thus increasing the brightness of the spherical transparent layer and further improving the brightness of the LED ...

Abstract

The invention relates to an LED (Light-Emitting Diode) lamp bulb capable of being connected with alternating-current power directly. The LED lamp bulb comprises a spherical light-transmitting layer, a lamp holder, a columnar reflecting layer, a plurality of LED chips, a circuit board and a plug, wherein the plurality of LED chips are arranged at the connection part between the spherical light-transmitting layer and the columnar reflecting layer, a taper angle formed between a sphere center of the spherical light-transmitting layer and the connection part between the spherical light-transmitting layer and the columnar reflecting layer is 120 degrees, and the LED chips are an LED chipset capable of being directly connected onto the alternating-current power. According to the invention, because two integrated-resistor LED chips are connected in parallel and a plurality of LED PN (Positive Negative) junctions of the two integrated-resistor LED chips are arranged in opposite heading directions, one integrated-resistor LED chip works at the positive semi-cycle of the alternating-current power, and the other integrated-resistor LED chip works at the negative semi-cycle of the alternating-current power, so that the LED chipset can work under the alternating-current power all the time.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an LED light bulb which can be directly connected to an alternating current. Background technique [0002] Using LEDs as lighting fixtures has the following advantages: first, the energy consumption of LEDs is 80% lower than that of incandescent lamps with the same light efficiency; second, LEDs have no harmful metal mercury and will not pollute the environment; third, the light emitted by LEDs has high purity . [0003] However, under the current background of advocating the establishment of a low-carbon society, LEDs with good energy-saving performance still need to be further improved, so that the effective lighting emitted by LEDs can be as much as possible, and the invalid or unused light can be reduced as much as possible. The lampshade is further improved to increase the brightness of the lighting as much as possible. [0004] In addition, existing LED chips cannot be directly conne...
