Abstract

A high-luminous-efficiency lighting device comprises a first lamp path, a plurality of first light sources, a second lamp path and a plurality of second light sources. The first lamp circuit comprises a plurality of first bending parts and a plurality of second bending parts which are arranged in a staggered mode, each first bending part protrudes towards one side of the first reference line, and each second bending part protrudes towards the other side of the first reference line. The first light sources are distributed on the second bending parts. The second lamp circuit is connected with the first lamp circuit in parallel and comprises a plurality of third bending parts and a plurality of fourth bending parts which are arranged in a staggered mode, each third bending part protrudes towards one side of the second reference line, and each fourth bending part protrudes towards the other side of the second reference line. The second light sources are distributed on the third bending parts.

Description

technical field [0001] The invention relates to a lighting device, in particular to a lighting device with high light efficiency. Background technique [0002] Due to the advancement of technology, the efficiency of lighting devices has also been greatly improved. In order to enhance the luminous effect of the lighting device, it is necessary to make the light emitted by the lighting device uniform. LEDs of the same batch are usually packaged in the same bag, and the quality and characteristics of these LEDs are usually relatively similar. Therefore, if a lighting device uses different batches of LEDs, the brightness of the lighting device may be uneven, which greatly affects its luminous effect. Therefore, a pack of LEDs can usually only be used for one lighting device, and the remaining LEDs can only be discarded, which increases the manufacturing cost of the lighting device. [0003] In addition, the existing lighting device may have two or more light paths, and each l...
