Abstract
The present invention provides an LED module capable of blue-light energy, which mainly comprises a blue LED chip and a packaging glue. The blue LED chip emits blue light. The packaging glue covers the light-emitting path of the blue LED chip. The packaging glue further includes a fluorescent powder. The amount of the fluorescent powder occupies 10% to 40% of the amount of the packaging glue. After the blue light excites the fluorescent powder, the white light is generated. The hue of the white light falls in hue coordinates (CIE 1931) and 8 nominal CCT ranges in the chromaticity diagram. The present invention controls the proportion of the fluorescent powder in the packaging glue, so that the blue light consumes most of its energy on exciting the fluorescent powders. Thereby, the proportion of the blue light in the white light is fewer.
