Patent ID: 7390109

Claim:
A light-emitting diode (LED) component comprising: a circuit board; an LED chip installed on the circuit board for emitting light, the LED chip comprising a plurality of light-emitting points; and a light direction-changing unit for changing direction of the light emitted by the LED chip, the light direction-changing unit comprising: a covering surface for covering the LED chip; and a reflecting surface comprising a plurality of reflecting points, a smallest included angle of a plurality of included angles between a normal line of at least one of the reflecting points and a plurality of connection lines passing through the reflecting point and the light-emitting points being larger than sin −1 (1/n), where n is a refraction index of the light direction-changing unit, wherein the reflecting surface of the light direction-changing unit comprises a conical indentation reflecting surface that is a curved surface formed by an arc line spinning around its tangent line.
