Description
TRAFFIC SIGNAL LAMP USING LIGHT EMITTING DIODES
Technical Field
[1] The present invention generally relates to a traffic signal lamp, and more particularly, to a traffic signal lamp using LEDs to enable a driver to more clearly recognize signals provided from the signal lamp. Background Art
[2] Generally, the progression and progressive directions of vehicles have been controlled according to on/off state of a signal lamp, and such a signal lamp has been converted into an LED from the electric bulb for use in consideration of generation of heat, power and a lamp life.
[3]
[4] A signal lamp(lOO) of prior art, like shown in Fig. 1, consists of a plurality of modules(l 10) requested for a signal system, and the modules(l 10) are mounted with monochromatic, that is, monochromatic LEDs that emit one color, instead of electric bulbs. The plurality of modules(l 10) are configured to display green(l 13), red(l 11), yellow(l 12), and an arrow(l 14), which are matched with progression, stop, standby, and direction instructions, respectively.
[5] However, the signal lamp(lOO) mounted with the monochromatic LEDs is requested to have at least one module(l 10) that should display each color and shape required for the signal system, that is, the red(l 11), the green(l 13), the yellow(l 12), and the arrow(l 14), respectively. Thus, the number of the LED modules(l 10) must be equipped as the same as the number of existing electric bulbs, resulting in an increase of product cost. Furthermore, since the number of the modules(l 10) turned on during signal transmissions is equal to that of the electric bulbs for use, it is hard for a driver to recognize instantaneous signals in case of bad weather. Disclosure of Invention Technical Problem
[6] It is therefore an object of the invention to provide a traffic signal lamp using LEDs to send all traffic signals with a desired minimum number of modules by mounting polychromatic LEDs which can emit at least 3 colors on modules of the signal lamp, and to reduce traffic accidents caused by unrecognizable traffic signals by enabling a driver to more clearly recognize the traffic signals through lighting of colors and shapes needed for the corresponding traffic signals over a wide range. Advantageous Effects
[7] According to the present invention, since LEDs that can emit many colors are applied to modules of a signal lamp, a desired minimum number of modules can be used, thereby reducing a cost. Furthermore, since corresponding traffic signals are widely lighted on the modules of the signal lamp, the user can more clearly recognize the traffic signals, thus traffic accidents caused by unrecognizable traffic signals can be reduced.

Mode for the Invention [19] The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which typical embodiments of the invention are shown. [20] [21] To accomplish the above object, the present invention provides a signal lamp for turning on/off LED modules to control the progression of a vehicle, and wherein the
LED modules are configured by mounting a plurality of polychromatic LEDs, and are lighted up in monochromatic and singular forms in case of a single signal while being lighted up in more than one color and the same form matched with each signal in case of simultaneous signals.
[22]
[23] The LED modules are configured in plural, and each module is lighted up in monochromatic and the same form for a single signal, whereas more than one color and more than one of the same forms matched with each signal are divided in module unit to light the modules in the event of simultaneous signals.
[24]
[25] The above LED modules are configured as an incorporated one, and are lighted in monochromatic and more than one of the same forms on the occasion of a single signal, while colors and more than one of the same forms matched with each signal are partitioned to light the modules in time of simultaneous signals.
[26]
[27] In a signal lamp for turning on/off LED modules to control the progression of a vehicle, the LED modules are configured by arraying a plurality of monochromatic LEDs in line by color, and are lighted in monochromatic and the same form in case of a single signal while being lighted in more than one color and form matched with each signal on the occasion of simultaneous signals.
[28]
[29] The LED modules are configured in plural, and each module is lighted up in monochromatic and the same form for a single signal, whereas more than one color and more than one of the same forms matched with each signal are divided in module unit to light the modules in the event of simultaneous signals.
[30]
[31] The above LED modules are configured as an incorporated one, and are lighted in monochromatic and more than one of the same forms on the occasion of a single signal, while colors and more than one of the same forms matched with each signal are partitioned to light the modules in time of simultaneous signals.
[32]
[33] Hereinafter, a traffic signal lamp using LEDs in accordance with the present invention will be described in detail on the basis of the accompanying drawings.
[34]
[35] Fig. 2 is a front view for illustrating that a plurality of modules mounted with polychromatic LEDs are turned on/off according to traffic signals, by a first embodiment of the present invention.
[36]
[37] A traffic signal lamp(lθ) in accordance with the present invention is composed of a plurality of LED modules(20) mounted with polychromatic LEDs that emit many colors, that is, at least 3 colors including red, green, and yellow.
[38]
[39] In the event of a single signal among the traffic signals, each of the modules(20) is simultaneously lighted in monochromatic or the same form, and on the occasion of simultaneous signals, the signals are divided in module unit to light the modules.
[40]
[41] For instance, in case of a single traffic signal indicating progressions(red, 23), stops(red, 21), standbys(yellow, 22), and turn-right and turn-left signs of a vehicle, one indicating color matched with the signal and indicating arrows(24) are simultaneously lighted on all of the respective modules(20).
[42]
[43] Moreover, in the event of simultaneous traffic signals including a turn-left sign for the progression of a vehicle, and a turn-left sign for the stop of the vehicle, indicating colors corresponding to progressions(green,26) or stops(red, 27) and indicating arrows(28) demanded for rotations are divided by the right/left modules(20) for lighting.
[44]
[45] Meanwhile, Fig. 3 shows a second embodiment for illustrating that one incorporated module mounted with polychromatic LEDs is turned on/off according to traffic signals. In an incorporated module(30) configured as one by roughly uniting a plurality of modules(20 of Fig. 2), for a single signal, one indicating color such as red(31), green(33), and yellow(32) is lighted over an entire range of the LED module(30), while more than one of direction indicating arrows(34) is lighted by being partitioned. For simultaneous signals, indicating colors(36,37) and indicating arrows(38) are lighted by being partitioned on the module(30).
[46]
[47] For example, in case of a progression or stop or standby of a single traffic signal of a vehicle, a selected one indicating color of the green(33) or the red(31) or the yellow(32) is lighted over an entire range of the module(30), and for the turn-right or turn-left sign, more than one of the direction indicating arrows(34) is lighted in the same form on the module(30).
[48]
[49] Also, as for simultaneous traffic signals including a turn-left sign for a progression of a vehicle, and a turn-left sign for a stop of the vehicle, one indicating color corresponding to the progression(green, 36) or the stop(red, 37) and more than one of the indicating arrows(38) demanded for rotations are partitioned on the modules(30) for lighting.
[50] [51] Meanwhile, Fig. 4 shows a third embodiment for illustrating that a plurality modules mounted with monochromatic LEDs arrayed in line by color are turned on/off according to traffic signals, in accordance with the present invention. In the event of a single signal among the traffic signals, the monochromatic LEDs having the same colo r are simultaneously lighted on each LED module(40). As for simultaneous signals, the monochromatic LEDs having the same color are simultaneously lighted by being partitioned according to each module(40).
[52]
[53] For instance, in case of a single traffic signal showing progressions(green, 43), stops(red, 41), standbys(yellow, 42), and turn-right/turn-left signs of a vehicle, one indicating color matched with the signal and indicating arrows(44) for displaying rotations are displayed on each module(40) by concurrently lighting the monochromatic LEDs having the same color.
[54]
[55] Furthermore, as for simultaneous traffic signals including a turn-left sign for a progression of a vehicle, and a turn-left sign for a stop of the vehicle, one indicating color corresponding to progressions(green, 46) or stops(red, 47) and indicating arrows(48) demanded for rotations are displayed as being partitioned according to each module(40) by concurrently lighting the monochromatic LEDs having the same color.
[56]
[57] On the other hand, Fig. 5 shows a fourth embodiment for illustrating that one incorporated module mounted with monochromatic LEDs arrayed in line by color is turned on/off according to traffic signals, in accordance with the present invention. In an incorporated module(50) configured as one by roughly uniting a plurality of modules(40 of Fig. 4), for a single signal among the traffic signals, the monochromatic LEDs having the same color are simultaneously lighted over an entire range of the module(50). In case of simultaneous signals, the monochromatic LEDs having the same color are concurrently lighted by being partitioned on the module(50).
[58]
[59] For example, as for a single traffic signal showing a progression(green, 53), a stop(red, 51), a standby(yellow, 52), and turn-right/turn-left signs of a vehicle, one indicating color matched with the signal and indicating arrows(54) for displaying rotations are displayed on the entire module(50) by concurrently lighting the monochromatic LEDs having he same color.
[60]
[61] In addition, as for simultaneous traffic signals including a turn-left sign for a progression of a vehicle, and a turn-left sign for a stop of the vehicle, one indicating color corresponding to a progression(green, 56) or a stop(red, 57) and indicating arrows(58) demanded for rotations are displayed as being partitioned on the module(50) by concurrently lighting the monochromatic LEDs having the same color.
[62]
[63] From now on, operations of a traffic signal lamp using LEDs in accordance with the present invention will be simply described as follows.
[64]
[65] As a plurality of modules(20, 40) mounted with LEDs where monochromatic LEDs are arrayed in line by color, or with polychromatic LEDs, or respective incorporated modules(30, 50) are turned on/off, traffic signals are provided to a user.
[66]
[67] First, when the polychromatic LEDs suggested in the first embodiment of the present invention are mounted on the plurality of modules(20), in case of a single signal, the polychromatic LEDs are concurrently lighted to display a selected either one of green(23) or red(21) or yellow(22) color which would indicate a progress or stop or standby of a vehicle on each module(20), or the arrows(24) that indicate rotational directions of the vehicle. In case of simultaneous signals, the signals are divided in module unit, and are concurrently lighted to display a selected one of colors that indicate the progressions(green, 26) or stops(red, 27) or standbys of the vehicle on more than one of one-sided modules(20), and to display the arrows(28) that indicate rotational directions of the vehicle on more than one of other-sided modules(20).
[68]
[69] When the polychromatic LEDs suggested in the second embodiment are mounted on the incorporated module(30) configured as one by roughly uniting the plurality of modules(20), in case of a single signal, one indicating color selected from the incorporated module(30), that is, the red(31), yellow(32) or green(33) color is lighted over an entire range, or the signal is lighted to display more than one of the indicating arrows(34) by partitioning the arrows(34). As for simultaneous signals, the signals are lighted to display one indicating color, that is, green(36) or red(37) color, and the indicating arrows(38) by partitioning the color and the arrows on the incorporated module(30).
[70]
[71] When the monochromatic LEDs suggested in the third embodiment are mounted on the plurality of modules(40) in line unit by color, in case of a single signal, the monochromatic LEDs having the same color on all the respective modules(40) are simultaneously lighted to display a selected one indicating color, that is, red(41), yellow(42) or green(43) color, and the indicating arrows(44). As for simultaneous signals, the monochromatic LEDs having the same color by being divided in module unit are concurrently lighted to display one indicating color, that is, green(46) or red(47) color on more than one of the one-sided modules(40), and to display the arrows(48) on more than one of the other-sided modules(40).
[72]
[73] When the monochromatic LEDs suggested in the fourth embodiment are mounted on the incorporated module(50) configured as one by roughly uniting the plurality of modules(40) in line unit by color, in case of a single signal, the monochromatic LEDs having the same color are lighted to display one indicating color, that is, red(51), yellow(52) or green(53) color selected over an entire range, and to display the plurality of indicating arrows(54). In the event of simultaneous signals, the monochromatic LEDs having the same color on the incorporated module(50) are lighted to display one indicating color, that is, green(56) or red(57) color and more than one of the indicating arrows(58) by partitioning the color and the arrows.
[74]
[75] As will be recognized by those skilled in the art, the innovative concepts described in the present application can be modified and varied over a wide range of applications. Accordingly, the scope of patented subject matter should not be limited to any of the specific exemplary teachings discussed.
