Abstract
A reflection-type optoelectronic semiconductor device has an LED chip disposed on a first conducting wire portion, a second conducting wire portion connected to the LED chip via a connection wire, a packaging body for sealing the LED chip and part of the first conducting wire portion and the second conducting wire portion, a reflecting face disposed in an opposite direction of a light emission face of the LED chip and surrounding the packaging body, and an optical spectrum conversion layer coated onto the packaging body. A primary light emitted by the LED chip is reflected to the optical spectrum conversion layer by the reflecting face to undergo light excitation for producing a secondary light. The primary light and the secondary light are combined to generate a mixed light. A lens can be placed in the travel direction of the mixed light to change the distribution of the mixed light.
