    摘要： A light emitting element (1; 310) includes a transparent substrate (2) and a plurality of light emitting diode (LED) chips (3; 14). The transparent substrate (2) has a support surface (210) and a second main surface (21B) disposed opposite to each other. At least some of the LED chips (3; 14) are disposed on the support surface (210) and light emitting surfaces (34) of the LED chips (3; 14) and at least a part of the support surface (210) form a first main surface (21A) where light is emitted from. Each of the LED chips (3; 14) includes a first electrode (16; 31A) and a second electrode (18; 31B). Light emitted from at least one of the LED chips (3; 14) passes through the transparent substrate (2) and emerges from the second main surface (21B). An illumination device (10; 10'; 11; 50; 301; 302; 303; 304) includes at least one light emitting element (1; 310) and a supporting base (5; 26; 324). The light emitting element (1; 310) is disposed on the supporting base (5; 26; 324), and an angle is formed between the light emitting element (1; 310) and the supporting base (5; 26; 324).
