Description

Improved integrated traffic signal lamp

The present invention relates to the formation of light reflection / induction in the same signal display LED string of an improved integrated traffic light, more specifically, an integrated traffic light using a plurality of LEDs.

Many single traffic lights using three-color or monochromatic LEDs or small light-emitting bodies have been devised, for example, Utility Model Registration Nos. 364151 and 385797 by Applicants.

Applicant's Utility Model Registration No. 385797 discloses a circular or polygonal yellow outer LED row consisting of yellow LEDs and an X-shaped red LED row consisting of red LEDs and red LEDs at four ends adjacent to the yellow outer LED row above. The present invention relates to an arrow-shaped green LED string consisting of green LEDs arranged in an approximately middle portion of the space portion in the housing of the housing, and an integrated traffic light with an opaque portion except for the LED arrangement portion of the space portion in the housing above.

The integrated traffic lights of Utility Model Registration No. 385797 described above clearly display traffic signals, such as progress, signal change notice, and stop, more clearly than conventional traffic signals, thereby making it easier for vehicle drivers and pedestrians to identify traffic signals. In the case of the straight signal and the left turn signal, the area of the LED mounting part of the housing is limited, so the number of the green LEDs is relatively smaller than that of the stop signal red LED and the preliminary signal yellow LED, so that the green signal is relatively clear under the same conditions.

The object of the present invention is to solve the above problems of the integrated traffic light of Utility Model Registration No. 385797 to provide a traffic light that displays the signals more clearly while using the same number of LEDs.

Applicants have continued their research to solve the above-described problems of integrated traffic lights using LEDs. As a result, a circular or polygonal yellow outer LED row consisting of yellow LEDs and red LEDs are formed on approximately the same plane of the space part of the traffic light housing. One arrow type consisting of an X-shaped red LED row composed of four red LEDs adjacent to the yellow outer LED row above and green LEDs disposed slightly to the right of the middle or middle portion of the space in the upper housing. The green LED string, the opaque portion excluding the LED arrangement portion of the space part in the housing, and the light reflection / induction path formed at least on both sides or the outer side of the green LED string can be solved to solve the problem of the green signal. This invention was completed.

The present invention can increase the clarity, brightness, and illuminance of the green signal (progression, left turn or right turn) which is smaller in size and smaller in number of LEDs in terms of space use efficiency.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
