PROXIMITY AMBIENT LIGHT SENSOR AND ITS MANUFACTURING METHOD

摘要

The present invention relates to a proximity ambient light sensor which can prevent pollution or damage of a lens by assembling a housing array to a printed circuit board array using an adhesive layer before being separated to an individual proximity ambient light sensor, and can reduce light interference, and can improve productivity by reducing manufacturing costs and time. The proximity ambient light sensor may include: a printed circuit board; a light emitting chip mounted in the printed circuit board; a light detection chip mounted in the printed circuit board; a light emitting lens part surrounding the light emitting chip; a light detection lens part surrounding the light detection chip; a housing which has a shape of surrounding the light emitting chip and the light detection chip, and has a lighting window corresponding to the light emitting lens part and a light detection window corresponding to the light detection lens part; and an adhesive layer installed between the housing and the printed circuit board.
