A lighting device has a power interface and a control circuit in communication with a program and the LEDs to simulate a flame. The program determines a first group of LED control integers to simulate a perpetual middle with a perpetual middle center and a perpetual middle range within which one or more of the LEDs are to be at least partially actuated. At least one LED is actuated based on the first group of LED control integers. A first target for simulating movement of the perpetual middle center toward the first target and a first acceleration value is defined. The program determines a second group of LED control integers based on the first target and the first acceleration value such that the perpetual middle center becomes closer to the first target. One or more of the LEDs is actuated based on the second group of LED control integers.

A solar spectrum-like LED structure, comprising a negative electrode for a three-dimensional integrated package, and a plurality of LED chips and resistors. The negative electrode for a three-dimensional integrated package is a three-dimensional structure comprising a plurality of planes. The plurality of LED chips is installed on the plurality of planes of the negative electrode for the three-dimensional integrated package. Light of different colors emitted by the plurality of LED chips forms a plane light source or a cone light source after being well mixed at an intersection point, thus simulating a solar spectrum. The invention enables manufacturing of a solar spectrum-like LED fluorescent lamp suitable for generating different bands of spectrums for the survival and metabolism of various organisms. In addition, the solar spectrum-like LED fluorescent lamp has a good color-rendering property and visual effect, and can be widely applied in the fields of general lighting, agriculture, animal husbandry and new biological energy sources.

A multi-dimensional lighting device is formed using such substrates. The multi-dimensional lighting device includes external mounting surfaces, each configured to provide mounting positions for one or more substrates. A flexible jumper device electrically couples a given substrate to an adjacent substrate, and provides a predefined clearance between surfaces of the same and exposed conductive surfaces of the lighting device. Each flexible jumper includes a surface mount device (SMD) capable of being placed by automated process, such as by pick-and-place machines. Such lighting devices are thus possible using automated processes in a high-volume, highly-precise manner.

The multiple LED regions share the same package housing but at least two LED regions are covered with different fluorescent layers for emitting lights with different optical characteristics.

When viewed in parallel to a central axis (C1), three LED substrates (4) form an equilateral triangle (T) that surrounds the central axis (C1) and are disposed equidistantly with respect to the central axis (C1).
