That is, the power lines 10 are arranged on one side and the other side of the main body 1 to form a pair, and each of the power lines 10 supplies power to the light source 300 that substantially provides light emission. Each line is made up of two wires.

Meanwhile, at least one pair of fixing members 20 connected to the power line 10 and for fixing the light emitting substrate 30 to be described below are connected to the pair of power lines 10, respectively. The connection groove 210 which exposes the power supply line 10 of this is provided.

At this time, the fixing member 20 is connected in the horizontal direction. In other words. The pair of fixing members 20 are horizontal because they are connected in the same line between the power line 10 on one side and the power line 10 on the other side. At this time, the pair of fixing members 20 are arranged in a multi-stage arrangement at predetermined intervals on the power supply line 10.

In addition, the connection groove 210 is formed to be recessed inward so that the power line 10 is exposed, thereby making an electrical connection with the light source 300 through this space.

As the length of the light emitting substrate 30 increases, the light source 300 As a way to solve the problem that it is difficult to supply a collective power.

Meanwhile, since FIG. 6A provides light emission in a unidirectional direction of the main body, the light source 300 of the light emitting substrate 30 is disposed toward the open side of the main body 1, and thus the light emitting substrate 300 is disposed. Fixing members 20 and power lines 10 fixed to each other are fixed to the sealing surface side opposite to the opening surface. At this time, the fixing is made through an adhesive means (not shown) formed on the bottom of the fixing member 20.

When the built-in light emitting substrate 30 is connected, it is possible to sequentially flash as shown in the figure. For example, when the light source 300 includes at least 11 power lines 10 connected to each of the 10 light emitting substrates 30 and the 10 light emitting substrates 30, respectively, the individual power supply units may be provided. In addition, power may be supplied to each of the light emitting substrates 30 in sequence. In this case, a driving controller for supplying power in order should be provided.

Again, as the driving controller outputs the light emitting signal for the sequential blinking function, power is sequentially input to each power line 10, or the power is cut off in turn so that the corresponding light emitting substrate connected to each power line 10 ( The light source 300 of 30 may be sequentially turned on or off, or may be repeatedly turned on or off.
