Description

  The present invention relates to an LED continuous substrate used as a channel letter or a signboard light source instead of neon or a fluorescent lamp.

  As a conventional technique, a plurality of light emitting means having a plurality of light emitting sections that emit light in different voltage regions, a power supply means for applying a voltage to the light emitting means via two power lines, and the power supply means And a voltage value switching means for changing the voltage applied to the light emitting means to a plurality of different voltage values within a predetermined time. (See Patent Document 1)

As another conventional technique, the current of all LEDs is equalized by dividing a large number of LEDs into a plurality of groups, providing a constant current circuit for each group, and aligning the output currents of the respective constant current circuits. There is a constant current LED substrate characterized by the following. (See Patent Document 2)
Japanese Patent Application No. 11-266155 Utility Model Registration No. 3105302

  The former is not divided and used without being hollowed out, and is different from the LED continuous substrate of the present invention.

  The latter enables the realization of a constant-current LED substrate with a small current variation and high efficiency and easy power supply design in applications where a large number of LEDs are driven simultaneously with a uniform current. It cannot be used by dividing it as in the present invention, or it can be used without a hollow.

  The present invention is intended to solve the problem of such a conventional configuration. A plurality of LED substrates are connected in series, and even if one LED substrate is divided and divided, It aims at providing the LED connection board | substrate which can light-emit.

In order to achieve the above object, according to the present invention, a plurality of LED substrates each provided with at least one LED are connected to one substrate, and cuts are formed in adjacent LED substrates.
In order to be able to divide and install one LED substrate or a plurality of LED substrates, contact points for power supply are provided at four positions in the vertical and horizontal directions.
A plurality of LED substrates are connected in series and formed into a single plate shape, and a hollow hole is formed in the cut to cut out the LED substrate at a required position inside.

1) A plurality of LED substrates can be connected in series, cuts can be formed in adjacent LED substrates, and each can be divided one by one, and when necessary, the required number can be applied as channel letters or a light source for signboards.
2) By providing power supply contacts at four locations on the top, bottom, left, and right of the LED substrate, one LED substrate or a plurality of LED substrates can be divided and used.
3) A plurality of LED boards are connected to form a single plate, and when the LED board at a required position inside is removed, a hollow hole is formed in the cut line so that a thread is formed in the hollow hole. By inserting a saw or the like and cutting along the cut line, it is possible to cut out the inside, for example, a signboard displaying characters or the like can be constructed.

The LED continuous substrate 1 of the present invention includes a plurality of LED substrates 2 each having four LEDs 2b connected to a single substrate 2a, and small holes 3a continuously provided around the adjacent LED substrates 2a. A notch 3 is formed by forming a V-shaped groove 3b, and positive and negative power supply contacts 4 are provided at four positions on the upper, lower, left and right sides of each LED board 2.
Further, hollow holes 5 are formed in corners (four corners) of each substrate 2a.
Further, a fixing hole 6 for fixing is formed in the center of each substrate 2a.
Reference numeral 7 denotes a current limiting resistor, and 8 is a jumper. (See Figures 1, 2, and 3)

An example of use of the LED continuous substrate 1 will be described below.
When the LED substrates 2 are removed one by one from the side, they can be broken by bending the cut 3 and can be easily divided and used (single unit).

Also, when removing the internal LED board 2..., A thread saw (not shown) or the like is inserted into the required hollow hole 5 and the surrounding (along the cut line 3) is cut and hollowed out. is there.
As shown in FIG. 4, it can be constructed by removing the Japanese characters.

  In the above embodiment, all the adjacent power supply contacts are energized, and even if they are hollowed out, the entire LED board emits light if the power supply contacts at one location are energized.
