[Conventional technology]

Figure 2 is a diagram showing the configuration of a conventional tube-type security light, where 1 is an AC plug and 2 is a plug. controller, 3 is a changeover switch installed in the controller, and 4 is a tube type retainer. A waterproof tube is attached to both ends of the red or yellow light-transmitting vinyl tube 5 in the cheap lamp body. caps 6a and 6b are attached, and the five leads pulled out from the controller 2. The cord wires 7a to 7e are passed into the vinyl tube 5 through the cap 6a, The two lead wires 7a and 7b are pulled out through the cap 6b and connected to the AC socket. 8 and is used to connect the next-stage tube-type security light. Lead wires 7c and 7d are connected to 24 or 2 incandescent bulbs 9a and 9b, respectively. Eight of them are connected in series, and one end of the lead wires 7c and 7d are connected to the switch 3, respectively. Connected to terminal a and terminal b, and the other ends of lead wires 7c, 7d and 7e are connected on the cap 6b side.

0003 The conventional tube security light configured in this way connects the AC plug 1 to the AC power source. When connected, the switch is activated by a control device in the controller 2 (not shown). The switch 3 switches between the a terminal side and the b terminal side at predetermined intervals, and connects to the lead wire 7c. The incandescent lamp 9a connected to the lead wire 7b and the incandescent lamp connected to the lead wire 7b are lit alternately. .

[Problem that the idea aims to solve]

Conventional tube security lights are incandescent lights connected in series and turned on alternately. The structure is structured so that if even one incandescent lamp breaks, the lead wire side will not light up. It becomes. In addition, because incandescent lamps are easily damaged, it is necessary to protect them, and the five leads are Since it is necessary to pass the cable through, a vinyl tube with a large diameter and high strength is used. There is a need to. In this way, conventional tube security lights have a short lifespan and require careful handling. There was a problem that The purpose of this invention is to obtain a tube-type security light that solves the above problems. Ru.

[Means to solve the problem]

The tube-type safety light according to the present invention uses a low-voltage DC power supply and a low-voltage DC power supply. A controller that switches the polarity of the output voltage at predetermined intervals and multiple light emitting diodes. The odes are connected at specified intervals and with different polarities, and the controller Two lead wires that are powered from the controller and a light transmittance that accommodates these two lead wires. It is made up of a synthetic resin tube with a

[0006]

[Effect]

Between two lead wires housed in a light-transparent synthetic resin tube The polarity of the applied DC voltage is switched between multiple light emitting diodes connected to the Each time, only the light emitting diode with forward polarity lights up, so each light emitting diode Flashes.

【Example】

FIG. 1 is a diagram showing the configuration of an embodiment of the present invention. In the figure, 10 is a low voltage DC power supply, for example a 100 volt AC commercial power supply. A DC voltage of 2 volts DC is generated. 2 is a controller, which controls the 2-pole 2-circuit switch 11 with a controller (not shown). It is switched at predetermined time intervals using a control circuit. 12 and 13 are light emitting diodes with an operating voltage of 2 volts, which are connected between lead wires 7a and 7b. are connected in parallel at predetermined intervals with alternately different polarities.

[0008] The tube security light configured in this way has the switch 11 of the controller 2 Each time it switches, light emitting diodes 12 and 13 light up alternately, and the vinyl tube It emits light through the tube 5 and functions as a security light.

[0009] In the above embodiment, the two lead wires 7a and 7b are pulled through the cap 6b. Connect it to socket 8 to supply power to the next stage tube security light body. However, even if the power is supplied by a lead wire different from lead wires 7a and 7b, good. In addition to dry batteries, the low voltage DC power supply 10 also includes secondary batteries, and solar power sources for secondary batteries. A combination of batteries, etc. can be applied.

0010 In addition, in the above embodiment, a 2 volt light emitting diode is connected between two lead wires. Although connected in parallel, if the low voltage DC power supply 10 is a car battery, , six light emitting diodes connected in series are connected in parallel between two lead wires. A connected configuration may be used.

[Effect of the idea]

According to the present invention, the number of lead wires inserted into the light-transmitting synthetic resin tube can be reduced. Light-emitting diodes are small and have excellent mechanical strength. This makes it possible to reduce the diameter of the light-transmissive synthetic resin tube, as well as extend its service life and This has the effect of providing a tube-type security light that is easy to handle.
