Abstract

Disclosed is a planar reciprocating electronic light emitting device consisting of a small amount of light emitting units arrayed in a row or more than one row transversely which being able to reciprocate up and down so as to exhibit much better visual effect than a large scaled displaying device thereby reducing fault rate and production cost, and increasing production efficiency.

Claims

1. A planar reciprocating electronic light emitting device comprising;

a reciprocating body 2 with a row or more than one row of light emitting units 1 being arrayed transversely in equal or unequal distance thereon;

a second timing pulley of driving shaft 10 conjoined and engaged to said reciprocating body 2 by a rotating shaft 3, said second timing pulley of driving shaft 10 further combined with a timing pulley of attaching rod 15 through a timing belt 11, said timing pulley of attaching rod 15 being conjoined and engaged to a first revolving rod 7;

a first timing pulley of driving shaft 12 being conjoined and engaged to a second revolving rod 4 with a rotating shaft 5 piercing through said first revolving rod 7 and said timing pulley of attaching rod 15, and one end of said second revolving rod 4 is pierced by said rotating shaft 3 interposed between said reciprocating body 2 and said second timing pulley of driving shaft 10, said first timing pulley of driving shaft 12 being combined to a timing pulley of attaching framework 16 via a timing belt 13, while said timing pulley of attaching framework 16 being engaged to a framework 19; and

said framework 19 accommodates a motor 20 therein which having one direct or indirect rotating shaft 18 piercing through said framework 19 and said timing pulley of attaching framework 16, and then conjoined with said first revolving rod 7.

2. The light emitting device of claim 1, wherein said timing pulley of attaching framework 16 and said framework 19 are statically engaged together, while said first timing pulley of driving shaft 12 is driven to rotate by said timing belt 13 which further drives said rotating shaft 5 and said second revolving rod 4;

while being engaged to said first revolving rod 7, said timing pulley of attaching rod 15 remains stationary with relative to said first revolving rod 7, said second timing pulley of driving shaft 10 is driven to rotate by said timing belt 11 which further drives said rotating shaft 3 and said reciprocating body 2 such that said motor 20 is able to drive said rotating shaft 18 and said first revolving rod 7, and further drives said second revolving rod 4 and said reciprocating body 2 to operate.

3. The light emitting device of claim 1, wherein the tooth ratio of said second timing pulley of driving shaft 10 to said timing pulley of attaching rod 15 is 2:

1, similarly, the tooth ratio of said timing pulley of attaching framework 16 to said first timing pulley of driving shaft 12 is also 2;

1.

4. The light emitting device of claim 1, wherein transmission of rotative motion between said second timing pulley of driving shaft 10 and said timing pulley of attaching rod 15, and between said first timing pulley of driving shaft 12 and said timing pulley of attaching framework 16 can be carried out by gears and machine method instead of depending on timing belts and timing pulleys.

5. The light emitting device of claim 1, wherein the distance between said rotating shaft 18 and said rotating shaft 5 is equal to the distance between said rotating shaft 3 and said rotating shaft 5, in addition, said first revolving rod 7 is provided with a balancer 8 at the other location from the place where said rotating shaft 5 pierces through, and similarly, said second revolving rod 4 is provided with a balancer 6 at the other location from the place where said rotating shaft 3 pierces through, said two arbitrarily shaped balancers 6 and 8 are for balancing high speed motion of said two revolving rods 7 and 4.

6. The light emitting device of claim 1, wherein if said reciprocating body 2 is considerably long, more than one set of said driving mechanism can be provided to drive said reciprocating body 2 for achieving a broader display effect.

7. The light emitting device of claim 1, wherein a photo detector 22 is installed at a proper location on said reciprocating body 2, and a position device 21 is provided at the vertical moving zone of said reciprocating body 2 for detecting the instant location of said reciprocating body 2.

8. The light emitting device of claim 1, wherein said light emitting units 1 can be mixed with various colored units such as three primary colors red, green and blue units for exhibiting more colorful effect.
