Abstract: Effect of inner lens is to change transmit direction of light from chip of light emitting diode (LED). Being gotten together in very small angle along direction perpendicular to central axis of chip of LED, most of light transmits around from side face. The inner lens and chip of LED are sealed together. The sealed LED module includes base; chip of LED installed on the base; bottom part of the inner lens is connected to the base. Chip of LED is located on central axis of the inner lens. Through refraction surface and total reflection surface of inner lens, side face of light source of LED transmits more beams collected by inner lens at direction of side face of LED. The invention enhances luminous efficiency of side face of LED.
