Abstract

The present invention provides an LED illuminator collimation module that can be installed in the optical engine of a projector. The LED illuminator collimation module comprises an LED base, a collimator, and a holder. The holder further comprises a first clamping holder and a second clamping holder. The collimator can be quickly fixed between the first clamping holder and the second clamping holder forming a ferrule, which utilizes a clip configuration to implement a quick clip fixing. On the other hand, between the holder and LED base, a positioning mechanism is used to provide an accurate secure fixing for the holder on the LED base so that the collimator can collimate the lights emitted from the LED on the LED base accurately and efficiently and can achieve optimized collimation effect.

Claims

1. An LED illuminator collimation module, comprising:

an LED base, an LED being on the LED base;

a collimator furnished on a position corresponding to the LED; and

a holder for holding the collimator, said holder further including a positioning mechanism for fixing the holder on the LED base.

2. The LED illuminator collimation module as claimed in claim 1, wherein the holder further comprises a first clamping holder and a second clamping holder.

3. The LED illuminator collimation module as claimed in claim 2, wherein a clip configuration is utilized to implement clip joint fixing between the first clamping holder and the second clamping holder.

4. The LED illuminator collimation module as claimed in claim 3, wherein the clip configuration further have a protruding lump fixture and a clip fixing part on corresponding positions of both the first clamping holder and the second clamping holder, which can combine with each other.

5. The LED illuminator collimation module as claimed in claim 4, wherein a side of the protruding lump fixture near the clip fixing part has an inclined plane.

6. The LED illuminator collimation module as claimed in claim 2, wherein the first clamping holder and the second clamping holder both have same figurations.

7. The LED illuminator collimation module as claimed in claim 1, wherein the positioning mechanism further has at least one positioning convex post and at least one positioning concave hole on corresponding positions of the holder and the LED base, which can combine with each other.

8. The LED illuminator collimation module as claimed in claim 2, wherein the collimator further has a circular flange, in addition, each of the first and second clamping holders has a semi-circle groove formed on a position corresponding to the circular flange, the semi-circle grooves of the first and second clamping holders can combine with each other for clamping and receiving the circular flange.

9. The LED illuminator collimation module as claimed in claim 1, wherein in addition to the LED base, the collimator and the clamping holder, the module further comprises a heat dissipater which is installed at a back of the LED base;

namely, the LED base is allocated between the heat dissipator and the holder.

10. An LED illuminator collimation module, comprising:

an LED base, an LED being on the LED base;

a collimator located above the LED of the LED base to collimate light; and

a holder having a first clamping holder and a second clamping holder, which can be separate from each other, and the first clamping holder and second clamping holder have a clip configuration which can combine together to hold the collimator between the first clamping holder and the second clamping holder, and also the holder further has a positioning mechanism for fixing the holder on the LED base.

11. The LED illuminator collimation module as claimed in claim 10, wherein the clip configuration further have a protruding lump fixture and a clip fixing part on corresponding positions of both the first clamping holder and the second clamping holder, which can combine each other.
