Novel collimating light emitting diode packaging structure

Packaging structure of a light emitting diode with an alignment function, which belongs to the packaging field of LED lighting applications in the light, which is characterized by a rotational symmetry of the collimating lens package light-emitting diode chip, so that the light emitted by the collimating lens with small divergence angle of the emergent light emitting diode, forming a directional the surface light source emission.

The surface light source can be used in the flashlight, the spotlight, the miner's lamp, the projector and other devices. Through the use of positive N shaped collimator lens to encapsulate the power type LED, the positive N edge of the LED lighting module can be obtained. A plurality of positive N shaped LED lighting modules are combined to obtain a larger area of directional emission light source.

In the invention, the light emitted by the LED chip of the approximate point light source is exported to form a uniform light beam, and the danger of the high brightness of the led to the human eye is eliminated.
