[0001]

BACKGROUND OF THE INVENTION This invention is in the case of measuring the optical characteristics of the LED array board, good reproducibility of the mounting position of the LED array board, also self having different focal lengths
Selfoc Lens Array (hereinafter, SL)
A ) , which is a light-measuring positioning mechanism of the LED array board that can measure at the measurement reference position even if it is exchanged for A.

2. Description of the Related Art When an LED array board is mounted at a measurement position and the relative position of the LED array board such as linearity, unevenness, and spacing is measured, the LED array board is held horizontally with respect to a measuring element. When measuring another LED array board, reproducibility of the mounting position is required.

[0003] Conventionally, it has been inefficient to fit both ends of the LED array board with a block gauge or the like. Also, for SLA with different focal length, dedicated LED
Without an array board holding adapter, measurement could not be performed. Such a prior art is described, for example, in Japanese Utility Model Application No. 2-85474.

According to this invention, the SLA plate is positioned by the positioning pins 4 mounted on the fixed plate, and the LED array board is positioned by the positioning pins mounted on the moving plate.
It is an object of the present invention to provide a light measurement positioning mechanism for an LED array board that can move a moving plate 5 with a vertical moving mechanism for an SLA plate having a different thickness and set the SLA plate at a measurement reference position.

[0005]

In order to achieve this object, according to the present invention, an SLA plate 2 on which an SLA for condensing light emitted from an LED array board 1 is mounted, a fixed plate 3 on which the SLA plate 2 is mounted, and Positioning pins 4 mounted on the fixed plate 3 for positioning the SLA plate 2 with respect to the LED array board 1, a moving plate 5 on which the LED array board 1 is mounted, and mounted on the moving plate 5 to position the LED array board 1. It includes a positioning pin 6 and a vertical moving mechanism 7 for moving the moving plate 5 up and down until the upper surface of the LED array board 1 contacts the lower surface of the SLA plate 2.

[0006]

Next, the configuration of the light measuring positioning mechanism of the LED array board according to the present invention will be described with reference to FIG. FIG.
1 is an LED array board, 2 is an SLA plate, 3 is a fixed plate, 4 is a positioning pin, 5 is a moving plate,
Reference numeral 6 denotes a positioning pin, and reference numeral 7 denotes a vertical movement mechanism.

The SLA mounted on the SLA plate 2 is an LED
The light emitted from the array board 1 is collected, and the fixed plate 3 is
Attach A plate 2. The positioning pins 4 are attached to the fixed plate 3 and position the SLA plate 2 with respect to the LED array board 1. The moving plate 5 carries the LED array board 1, and the positioning pins 6 are attached to the moving plate 5 to position the LED array board 1. The vertical moving mechanism 7 moves the moving plate 5 up and down until the upper surface of the LED array board 1 contacts the lower surface of the SLA plate 2.

When placing the LED array board 1 on the moving plate 5, the positioning pins 6 are inserted into the reference holes of the LED array board 1. When placing the SLA plate 2 on the fixed plate 3, the positioning pins 4 attached to the fixed plate 3 are inserted into the reference holes of the SLA plate 2.

Next, a front view of FIG. 1 will be described with reference to FIG. 2H is a measurement reference position, and the light emission of the LED array board 1 condensed by the SLA placed on the SLA plate 2 is measured at the measurement reference position 2H by a photometer not shown.

Next, an external view of the LED array board 1 will be described with reference to FIG. 3A is a reference hole, and 1B is an LED.
The array 1C is light emitted from the LED array 1B.
The LED array board 1 has a reference hole 1A and an LED array 1B mounted thereon, and emits light 1C in one direction. Therefore, when mounting on the moving plate 5, the light 1C of the LED array board 1 is emitted upward.

Next, an external view of the SLA attached to the SLA plate 2 will be described with reference to FIG. FIG. 4 shows an example of an SLA having a different focal length.
mm, and the SLA2D has a focal length of 32.1 mm.

[0012]

Next, the structure of an embodiment of the vertical movement mechanism 7 will be described with reference to FIG.
This will be described below. FIG. 5 shows a state in which the SLA plate 2A for the SLA 2C having a short focal length is mounted on the fixed plate 3. In FIG. 5, 7A is a movable plate, 7B is a ball plunger, 7C is a V groove, 7D is a positioning block, 7E is a guide, 7F is a knob, and 7G is a spring. The vertical movement mechanism 7 is constituted by 7A to 7G.

If the SLA plate 2B having a different thickness is attached, the position of the lower surface of the SLA plate 2A will be different, but this can be dealt with by moving the positioning block 7D for fixing the position of the LED array boat 1 up and down.

Next, the SLA for the SLA2B having a long focal length
The state where the plate 2D is mounted on the fixed plate 3 will be described with reference to FIG. 5 and 6 show a state in which the movable plate 7A is pushed down, in which the ball plunger 7B attached to the movable plate 7A enters the V groove 7C below the positioning block 7D, and the movable plate 7A is fixed. It is.

Next, a state in which the SLA plate 2A and the LED array board 1 are mounted, the positioning block 7D is fixed, and the movable plate 7A is pushed up will be described with reference to FIG. FIG. 7 shows that the ball plunger 7B attached to the movable plate 7A from FIG. 5 enters the upper V groove 7C of the positioning block 7D, and the movable plate 7A is fixed.
The moving plate 5 is pushed up by the spring 7G to hold the LED array board 1.

Next, the state in which the SLA plate 2B and the LED array board 1 are mounted, the positioning block 7D is fixed, and the movable plate 7A is pushed up will be described with reference to FIG. In FIG. 8, the ball plunger 7B attached to the movable plate 7A from FIG. 6 enters the V groove 7C on the upper side of the positioning block 7D, the movable plate 7A is fixed, and the movable plate 5 is pushed up by the spring 7G to lift the LED array board 1. It is in the state of being held.

In FIGS. 5 to 8, when the SLA plate 2A is mounted and when the SLA plate 2B is mounted, the pressing force of the spring 7G when the movable plate 7A is pushed up becomes constant. The SLA 2D having a long focal length can be pressed with the same pressure by replacing the SLA plate 2B with a thicker SLA plate 2B and changing the position of the moving plate 5.

[0018]

According to the present invention, the SLA plate 2 is positioned by the positioning pins 4 mounted on the fixed plate 3, and the LED array board 1 is positioned by the positioning pins 6 mounted on the moving plate 5.
Since the moving plate 5 is moved by the vertical moving mechanism 7 for the SLA plates having different thicknesses, the SLA plate can be set at the measurement reference position.
