Problems solved by technology

[0002] Existing LED light bulbs usually include a transparent lamp body and a lamp holder. A flexible LED light strip is installed in the lamp body. A transformer module is installed in the lamp body to convert the mains power into a low-voltage power supply to provide power for the flexible LED light strip. The flexible LED light strip generally has a strip-shaped main body, and the front of the main body is provided with a number of LEDs arranged at intervals along its length direction. Angle lighting needs to set multiple flexible LED strips in the lamp body, so that the bulb has multiple light-emitting surfaces to achieve large-angle lighting of the bulb (such as the attached figure 1 As shown), the structure is complex and inconvenient to install

Abstract

The invention relates to an LED (Light-Emitting Diode) lamp bulb which comprises a transparent lamp body and a lamp cap. An LED flexible circuit board electrically connected with the lamp cap is arranged in the lamp body; the LED flexible circuit board is provided with a strip main board body; and the main board body is provided with a plurality of LEDs which are arranged at intervals along the length direction of the main board body. The LED lamp bulb is characterized in that each first long edge of the strip main board body extends to form at least one bent lateral board body; and each lateral board body is provided with an LED electrically connected with the main board body. The LED lamp bulb has the advantages that two long edges of the strip main board body extend to form a plurality of lateral board bodies which are arranged at intervals and are bent and each lateral board body is provided with the LED electrically connected with the main board body, so that peripheral large-angle illumination can be implemented and a light emitting surface is large.

Description

(1) Technical field [0001] The invention relates to an LED light bulb. (2) Background technology [0002] Existing LED light bulbs usually include a transparent lamp body and a lamp holder. A flexible LED light strip is installed in the lamp body. A transformer module is installed in the lamp body to convert the mains power into a low-voltage power supply to provide power for the flexible LED light strip. The flexible LED light strip generally has a strip-shaped main body, and the front of the main body is provided with a number of LEDs arranged at intervals along its length direction. Angle lighting needs to set multiple flexible LED strips in the lamp body, so that the bulb has multiple light-emitting surfaces to achieve large-angle lighting of the bulb (such as the attached figure 1 As shown), the structure is complicated and the installation is inconvenient. (3) Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention prov...
