Description

LED lighting bulb

technical field

The utility model relates to a lighting device, in particular to an LED lighting bulb.

Background technique

Compared with ordinary incandescent lamps and energy-saving lamps, LED lighting bulbs have the advantages of environmental protection, low energy consumption at the same lighting effect, and long service life. It can be said that LED lighting bulbs are an inevitable trend to replace incandescent lamps and energy-saving lamps. However, the LED lighting bulbs in the prior art have poor versatility with common incandescent lamps and energy-saving lamp lamp holders, which has become an obstacle for LED lighting bulbs to replace incandescent lamps and energy-saving lamps. At the same time, in the prior art, in order to make the power of the LED lighting bulb meet the usage requirements, it is common practice to install a plurality of LED lamp beads, and this practice destroys the overall sense of the structure of the LED lamp.

Utility model content

The purpose of the utility model is to provide an LED lighting bulb with good adaptability to common incandescent lamps and energy-saving lamp sockets.

Another purpose of the present utility model is to provide an LED lighting bulb with a better sense of integrity.

The technical scheme provided by the utility model is as follows: Construct an LED lighting bulb, including a lamp cap, a lamp holder, a lampshade, a circuit board accommodated in the lampshade, and several LED lamp beads installed on the circuit board, the lampshade is in the shape of a hemisphere The lamp cap is a spiral lamp cap, and there is a step-shaped undercut on the lower edge of the lampshade. Correspondingly, the upper part of the lamp holder is hemispherical, and a ring-shaped protrusion matching the lampshade is provided on the inner side of the upper edge of the lamp holder. , the lower part of the lamp socket is provided with a connecting part adapted to the lamp cap.

The lampshade is made of transparent or translucent material.

The circuit board includes an LED light-emitting board, an insulating gasket, and a switching power supply board in order from top to bottom. The LED lamp beads are arranged on the LED light-emitting board, and their pins pass through the LED light-emitting board, the insulating gasket and Switching power board connection.

The utility model has the following advantages: the lower part of the lamp holder is provided with a connecting part adapted to the lamp holder, which enhances the compatibility with the lamp holder of ordinary incandescent lamps and energy-saving lamps; Buckles and ring-shaped protrusions enhance the overall sense of the lamp.

Detailed ways

Referring to Fig. 1, Fig. 2 and Fig. 3, an LED lighting bulb is provided, including a lamp cap 3, a lamp holder 1, a lampshade 2, a circuit board 4 accommodated in the lampshade 2, and several LED lamps mounted on the circuit board 4 Bead 41, the lampshade 2 is hemispherical, the lampshade 2 is made of transparent or translucent material, and the lower edge of the lampshade 2 is provided with a stepped undercut 21, correspondingly, the upper part of the lamp holder 1 is hemispherical, and the lamp holder The inner side of the upper edge of 1 is provided with a ring-shaped protrusion 11 that matches the lampshade 2. When installing, you only need to snap the step-shaped undercut 21 into the inner side of the ring-shaped protrusion 11, which is convenient for installation. The top of 1 is also in the shape of a hemisphere, and the two become one and integrated into one.

A connecting portion 12 adapted to the lamp cap 3 is provided at the lower part of the lamp holder 1 . The lamp holder 3 is a lamp holder with an international universal screw thread, and of course it can also be a bayonet-type lamp holder, which enhances the adaptability of the bulb and the common lamp holder, and further enhances the ability of the LED lighting bulb to replace traditional incandescent lamps and energy-saving lamps.

The circuit board 4 includes an LED light-emitting board 42, an insulating pad 44, and a switching power supply board 43 from top to bottom. Sheet 44 and is connected with switching power supply board 43. In this way, more LED lamp beads can be arranged on the LED light-emitting board 42 to meet usage requirements.
