Abstract: A light source unit not only applies red light and infrared light to promote immediate cellular activity, but also applies the light to a femoral epiphysis area (first area) and a tibial epiphysis area (second area) together so that a stimulating device for a growth plate includes a light source unit that directly emits light of 600 to 1100 nm to a femoral epiphysis area (first area) and a tibial epiphysis area (second area) where the growth plates are distributed.

Abstract: The present invention provides an LED module which is easily manufactured and has thermal durability and excellent color reproducibility. An LED module according to an aspect of the present invention comprises a substrate; at least one LED bare chip mounted on the substrate; and at least one color conversion sheet formed on the LED bare chip and including a phosphor, in which the color conversion sheet is formed so as to cover at least one LED bare chip and a height of a region corresponding to the LED bare chip in the color conversion sheet is different from a height of a region not corresponding to the LED bare chip in the color conversion sheet.
