Description

technical field [0001] The invention relates to a structure of a light-emitting diode lamp with a relatively large lighting angle, in particular to a plurality of branch side plates that can bend the three-dimensional structure circuit substrate of the multi-sided LED light source module into different planes, and the LED The light-emitting element is placed on the side plate of the supporting piece, so that the lamp can emit a large lighting angle. Background technique [0002] The light-emitting principle of LED is to use the inherent characteristics of semiconductors. It is different from the previous incandescent lamp’s heating and light-emitting principle, but it will emit light when the current flows forward into the PN junction of the semiconductor, so LED is called cold light. . Due to the advantages of high durability, long life, light weight, low power consumption and no harmful substances such as mercury, LEDs can be widely used in the lighting equipment industry...

Problems solved by technology

[0005] In the above-mentioned existing lamps, since the LED light-emitting element 22 is arranged on a flat substrate 20, the LED light-emitting element 22 is irradiated above the substrate 20, so that the illumination of the lamp can only reach 180 degrees at most, and a larger angle cannot be obtained. The lighting effect is the shortcoming of the current LED lamps, not to mention that the US Energy Star (Energy.star) has partly stipulated that LED bulbs should replace traditional light bulbs, and their luminous angle should be greater than 270 degrees, which is still difficult to achieve with the current LED lamps. this specification
