PURPOSE: To use also light emitted to above from a light-emitting diode chip by a method wherein light, which turns above the chip directly from the chip or via a reflective cup, is made to reflect in a plurality of side surface directions of light-transmitting resins. CONSTITUTION: Reflective surfaces 17 make light, which directs above a light- emitting diode chip 12 directly from the light emitting diode chip 12 or via a reflective cup, reflect totally in the side surface (lateral) directions of light- transmitting resins. That is, emitted light from the chip 12 is led above the chip 12 directly from the chip 12 or via the reflective cup and the light led above is reflected in the side surface directions of the two different light- transmitting resins 13 by the reflective surfaces 17, and is emitted to the outside from the side surfaces of the resins 13. Thus, light is emitted to the outside as an output from the upper surface and side surfaces of the chip 12, whereby the output of the chip 12 can be made a higher output as compared with the output of light emitted only from the side surfaces of a conventional light- emitting diode chip. |
