Description

Improved integrated traffic signal lamp

The present invention relates to an improved integrated traffic light, particularly a traffic light that can generate a green signal, a yellow signal, and a red signal with only one traffic light by arranging a plurality of green, yellow, and red small light emitters therein.

At present, two to four traffic lights are installed in a horizontal or vertical direction at intersections or crosswalks of various roads, providing signals to the driver and the driver such as driving (going), changing signals, and stopping. The current traffic lights are used in such a way that they are bulky, heavy, consume a lot of power, and thus, there is a problem in that it is difficult to install the props and supports and requires a lot of space. In order to solve these problems, Utility Model Registration No. 1990-18042 (Traffic signal display device using high brightness three-color LED) and Patent Application No. 1998-15057 (Single traffic signal lamp supporting various colors and displays) are proposed. However, it did not receive a utility model registration or a patent, nor was it put to practical use.

Recently, Utility Model Registration Nos. 325793 (integrated traffic lights) and No. 332507 (mono-traffic traffic lights using three-color light-emitting diodes) have been registered but have not been requested for technical evaluation and have not been put into practical use.

The common problem and problems of the above two registered utility models is that they are composed of compactly arranged small lamps or LED light emitters. That is, the light emitter is densely located in the entire traffic light, and even if only a part of the light is turned on, the contrast with the light that is not lit is weak, and the brightness of the stop light and the progress light signal displayed by the lit light is satisfied. There is an unavoidable flaw.

In addition, the known traffic light did not serve as a traffic light to the color blind people who cannot distinguish between green, yellow, and red, and therefore, the color blind people could not receive a driver's license.

The present invention aims to provide an integrated traffic light having a satisfactory brightness by solving the above drawbacks of the conventional traffic light.

The present invention also aims to provide an integrated traffic light with low power consumption, light weight, small volume, and various signal manipulation.

The present invention also aims to provide an integrated traffic light that generates a traffic signal that can be distinguished by a person who is color blind.

Outer yellow bulb row consisting of a number of small red bulbs (R), two rounded outer bulbs of red (R), and a small green bulb (G) consisting of two circular outer bulbs X-shaped red bulb group and a plurality of X-shaped red bulbs (R) in the inner space partitioned by the bulb array (G) and the outer bulb array above (i.e., the inner outer green bulb array in FIG. 1). An integrated traffic light consisting of green light bulbs (G) and an arrow-shaped inner green light bulb group for a straight / left turn signal, and an opaque portion (S) which is made of black space and black space above is shown. have.

The operating state of the integrated traffic light including yellow, red and green small bulbs and opaque parts arranged as shown in FIG. 1 will be described below.

According to the operation of the control circuit, the integrated traffic signal lamp according to the embodiment of the present invention lights only the red small bulbs R as shown in FIG. 2A, and stops only the small yellow bulbs Y as shown in FIG. 2B. The signal is operated by turning only the green small bulbs G as shown in FIG. 2C, and the left turn / straight simultaneous signal is turned on by not turning on the inner green small bulb group for the left turn display among the green small bulbs G as shown in FIG. 2D. Only the signal may be displayed, and the left turn signal may also be displayed by not lighting the internal green small bulb group for straight display.

In addition, the arrow of the progress (go straight, left turn) signal ( By moving the corresponding green compact bulbs (G) in sequence as moving the part in the direction of progress, it is possible to facilitate the traffic signal identification of general drivers and to enable the traffic signal identification of people with color blindness.

In Figure 1, the outer bulb is shown an embodiment of a circular, it can be configured as a polygon, such as triangular, pentagonal, pentagonal, hexagonal or separate. The outer bulb sequence may be circular in the same shape regardless of the green, yellow, or red signal (see FIG. 1), or may be a polygon different from each signal.

In addition, the traffic light of Figure 1 can be installed by hanging between the strong struts and the supporting struts do not need a horizontal support rod.

By modifying the embodiment of FIG. 1 of the present invention having the above configuration, the outer bulb array may be one, three or more, for each of green, yellow, and red, depending on the required illuminance and brightness. It can be changed as needed, and one of the arrow-shaped green bulb groups for left turn signal and straight signal can be eliminated if necessary, or the double signal can be excluded and the preliminary signal can be excluded. It may be replaced by all or part of the flashing red bulb. In addition, the X-shaped inner red bulb group may be omitted to improve the brightness, and the outer green bulb string may be omitted for cost reduction, and one of the X-shaped inner red bulb groups that crosses the interior space as needed, such as a small traffic signal. You can also exclude straight red bulbs. Furthermore, small bulbs can be replaced with LEDs.
