Abstract

The present invention discloses an optical testing device includes a base, a holder, and a number of illuminating modules. The base defines a sliding groove extending along a first direction in a top surface thereof. The holder slides along a second direction on the top surface of the base. The interval regulator is connected to the holder. The illuminating modules are slidably received in the sliding groove. Each of the illuminating modules comprises a circuit board and a single lighting element set on the circuit board. The interval regulator drives the holder to slide along a second direction so that a distance between the holder and the illuminating modules is regulated. The first direction is not parallel to the second direction.

First claim

What is claimed is:

1. An optical testing device comprising:
a base defining a sliding groove extending along a first direction in a top surface thereof;
a holder sliding along a second direction on the top surface of the base;
an interval regulator connected to the holder; and
a plurality of illuminating modules slidably received in the sliding groove;
wherein each of the illuminating modules comprises a circuit board and a single lighting element set on the circuit board, the interval regulator drives the holder to slide along a second direction so that a distance between the holder and the illuminating modules is regulated, and the first direction is not parallel to the second direction, wherein the sliding groove has a predetermined width along a direction perpendicular to a top surface of the base, and the illuminating module slides along the width direction of the sliding groove in a predetermined range;
a height regulator set above the sliding groove along a direction perpendicular to the top surface of the base, wherein the height regulator comprises a driving pole telescopically extending along the width direction of the sliding groove, and a distal end of the height regulator is connected to the illuminating modules to regulate a height of the illuminating modules along the width direction of the sliding groove.

2. The optical testing device of claim 1 , wherein the base defines a sliding rail extending along the second direction in the top surface thereof, the holder comprises a holding surface, a connecting surface, and a sliding block formed on the connecting surface corresponding to the sliding rail, and the holder is slidably connected to the sliding rail via the sliding block.

3. The optical testing device of claim 1 , wherein the interval regulator is set on the top surface of the base, the interval regulator comprises a substrate and a driving rod on the substrate, the driving rod telescopically extends along the second direction, and a distal end of the driving rod is connected to the holder to drive the holder to slide.

4. The optical testing device of claim 3 , wherein the holder comprises a first periphery closing the sliding groove and a second periphery opposite to the first periphery, the interval regulator is set on the base and located at a side close the second periphery, and the distal end of the driving rod is connected to the second periphery.

5. The optical testing device of claim 1 , wherein the interval regulator is a micrometer.

6. The optical testing device of claim 1 , the optical testing device further comprising a plurality of spacers inserted a gap between two adjacent illuminating modules, wherein the spacers are used to precisely regulate an interval between each two adjacent illuminating modules.

7. The optical testing device of claim 1 , wherein the first direction is perpendicular to the second direction.
