Abstract

The present invention relates to a substrate structure for LED lighting, the structure being capable of improving the hemispherical intensity distribution of a lighting device in which an LED is used, thereby improving the light efficiency of the lighting device. The substrate structure includes a first substrate for mounting a first LED thereon and three second substrates, each for mounting a second LED thereon. The second substrates are coupled to the first substrate such that the second substrates are perpendicular to the first substrate and are arranged at an angular interval which is within a range of 115° to 125° with respect to each other in a cross-sectional view taken parallel to the first substrate. One or more second substrates of the three second substrates are provided with one or more control circuits for controlling operation of either of or both of the first LED and the second LED, in which the control circuit is disposed in an end portion of the second substrate in a direction perpendicular to the first substrate.
