实施例一
如图1和图2所示，本实施例提供的一种交通信号光源2，包括底座21、灯柱22、信号灯组23、信号灯壳架24、信号控制机（图未示）以及第一发光件25；根据交通法规规定，交通信号灯大致分为机动车信号灯、非机动车信号灯、人行横道信号灯、方向指示指示灯（箭头信号灯）、车道信号灯、闪光警告信号灯、道路与铁路平面交叉道口信号灯等，因而交通信号光源2的底座21可设置在人行横道线1一侧或其他位置，具体可依据实际情况和具体指示要求来确定，交通信号光源2可用以指示人行横道线1附近的行人，亦可用以指示行车线处的车辆，还可用以指示铁道线上或站台附近的列车等，此处不作唯一限定；上述灯柱22设置在底座21上，信号灯组23用于发出信号指令（信号灯组23通常由红灯、绿灯、黄灯组成，红灯表示禁止通行，绿灯表示准许通行，黄灯表示警示转红灯，当然，用以指示人行横道线1行人通行的信号灯组23一般只有红绿两种颜色，因而信号指令可分为禁止通行、准许通行或警示的一种或几种），信号灯壳架24用于将信号灯组23固定在灯柱22上，该交通信号光源2还包括用于控制信号灯组23工作状态且为信号灯组23提供直流工作电压的信号控制机；灯柱22上设置有用于与信号灯组23发出相同信号指令的第一发光件25，信号控制机与第一发光件25电连接；在本实施例中，可选地，灯柱22包括具有内腔的透光壳体，第一发光件25设置在内腔中，具体灯柱22壳体材质可为铝合金、PMMA（聚甲基丙烯酸甲酯/亚克力）、PC板（聚碳酸酯）或PS板（聚苯乙烯）等，此处不作唯一限定；在本实施例中，可选地，第一发光件25设置在灯柱22的侧壁上，即可将第一发光件25设置为一能够贴附或沿灯柱22侧壁固定的长条形的灯条，具体固定方式此处不作唯一限定；需要说明的是，在本实施例中，灯柱22的第一发光件25还可包括用于显示文字的若干灯珠，灯珠可选为LED灯珠；如此，通过设置信号控制机，以控制信号灯组23工作状态且为信号灯组23提供直流工作电压，且灯柱22上设置第一发光件25，使得该交通信号光源2一方面实现亮度高，视觉宽，减少交通信号灯设置数量，避免资源浪费，另外，该光源结构便于远离停车线车辆驾驶人员、靠近停车线车辆拥挤时的车辆驾驶人员以及货车后端跟行的车辆驾驶人员及时准确地识辨灯光信号，并加强人行安全警觉；另一方面，全部灯体采用低压直流传输代替传统高压交流传输，无安全隐患，使用寿命长，结构可靠且便于维护。
在本实施例中，作为进一步优化，交通信号光源2还包括设于人行横道线1且用于与信号灯组23发出相同信号指令的第二发光件26，信号控制机与第二发光件26电连接。具体地，第二发光件26可为多个，多个第二发光件26分别设置在人行横道线1的多个横道线10上，多个第二发光件26与多个横道线10分别一一对应；当然，第二发光件26也可为单个或两个，可垂直人行横道线1的多个横道线10并设置于人行横道线1上或人行横道线1的相对两侧；另外，第二发光件26可同时具有设置在人行横道线1的多个横道线10上的发光件和垂直于横道线10并设置于人行横道线1的相对两侧的发光件，且前者的发光件与后者的发光件可发出不同颜色的光，以向被指挥对象发出不同的信号指令，此处均不作唯一限定。
在本实施例中，作为进一步优化，每一第二发光件26均为长条形的LED地埋灯；显然地，第二发光件26可为长条形或其他规则形状，也可设置为其他较为醒目或具有美感的不规则形状，此处不作唯一限定。
需要说明的是，第二发光件26与信号灯组23发出相同信号指令的前提为：该第二发光件26与信号灯组23设置在同一路口且均对同一侧行人进行信号指示；如若第二发光件26与信号灯组23设置在同一路口，且第二发光件26用于对行人进行指示，信号灯组23用于对与行人同侧的车辆进行指示，则第二发光件26也可根据实际道路交通指挥规则设置为与信号灯组23发出相反的信号指令，即信号灯组23红灯亮起禁止车辆通行，第二发光件26绿灯亮起准许行人通行；故而，第二发光件26发出的信号指令与信号灯组23发出的信号指令的关系取决于信号灯组23的设置位置和作用，此处不作唯一限定。
另外，交通信号光源2还包括分别电连接于信号控制机的红外感应设备（图未示）及语音播报设备（图未示），此处的红外感应设备也可为雷达感应设备或其他感应设备，此处不作唯一限定；具体地，红外感应设备及语音播报设备可配合上述第二发光体26一并对人行横道线上的行人给予警示，例如当第二发光体将亮起红灯时，红外感应设备可将探测得到的人行横道线上的行人情况反馈至信号控制机，进而控制语音播报设备发出相应的指示，诸如请尚未通过的行人快速通过、注意安全之类；如此时红灯亮起，则语音播报设备发声禁止行人通行；该结构进一步加强了行人的安全警觉，减少了交通安全事故的发生概率，进一步保障了人们的人身财产安全。另外，在本实施例中，作为进一步优化，交通信号光源2还可包括电连接于信号控制机的投影设备（图未示），该投影设备可设置在灯柱22上用以向地面或指定投影区域进行投影，进而配合信号灯组23、第一发光件25、第二发光件26等向被指挥对象发出各种信号指令。
交通信号光源2工作过程为（以交通信号光源2的信号灯组23发出禁止通行的信号指令为例）：信号灯组23通常亮起红灯或发红光的同时出现行人站立图案，此时，第一发光件25、第二发光件26可同时跟随信号灯组23出光并发出相同信号指令，即信号灯组23亮起红灯后，第一发光件25、第二发光件26可同步亮起红灯，从而警示行人及车辆此车道禁止通行，当然，第一发光件25、第二发光件26也可在出光的同时形成方向指示图案或倒计时动态图案等；由于各灯体亮度高，视觉宽，便于远离停车线车辆驾驶人员识辨灯光信号，亦便于靠近停车线拥挤车辆驾驶人员及货车后端跟行的车辆驾驶人员及时、准确观察灯光信号，有效改善智能交通安全，由于在人行横道线1附近灯柱22上设置第一发光件25及在人行横道线1上设置第二发光件26，加强了车辆及行人的安全警觉，便于车辆驾驶人员识别的同时，减少了交通安全事故，从而使得交通秩序更为稳定，人们的人身财产安全得到进一步保障。另外，由于该交通信号光源2警示范围较广，从而减少了交通信号光源2设置数量，进而大幅降低了灯架、灯柱22等部件的制造、装配、运输成本，减少了电能消耗，节能环保。
在本实施例中，作为进一步优化，信号控制机包括电源模块和连接在电源模块与信号灯组23之间的电路保护模块，其中电源模块可为第一发光件25、第二发光件26提供直流工作电压，即用低压直流驱动电路代替传统高压交流传输电路，避免了在灯柱22或各灯体中设置高压交流电源及器件，同时，电路保护模块可具有过流保护、过压保护或短路自保护自恢复功能，运维人员日常维修维护灯体时无需停电操作，大幅降低了维护难度和成本，减少影响交通，结构可靠，灯体被水浸泡状态下仍可正常工作，工作稳定性高，使用寿命长。
实施例二
下面结合附图1及附图3仅就与前述实施例中不同之处作详细说明。
在本实施例中，作为进一步优化，信号灯组23包括用于向灯柱22的第一侧22a发出信号指令的第一灯组231及用于向灯柱22的第二侧22b发出信号指令的第二灯组232，第一侧22a和第二侧22b朝向方向可为互相垂直的两个方向，也可呈一定夹角设定，具体以实际情况为准，此处不作唯一限定；第一灯组231和第二灯组232能够发出的信号指令种类可相同亦可不同，同一时间发出的信号指令可相同亦可不同，此处不作唯一限定；第一发光件25包括第一灯条251和第二灯条252，第一灯条251设置在灯柱22的第一侧22a的侧壁上且用于与第一灯组231发出相同信号指令，第二灯条252设置在灯柱22的第二侧22b的侧壁上且用于与第二灯组232发出相同信号指令，信号控制机分别与第一灯组231、第二灯组232、第一灯条251以及第二灯条252电连接；这样，以位于灯柱22第一侧22a的车辆为例，其可通过辨认第一灯组231和第一灯条251的出光情况得知该人行道的交通信号指令，该结构使得光源亮度高、视觉宽，有效地提高了交通信号光源2的警示作用。
在上述交通信号光源2工作时，以交通信号光源2放置在路口处且第一灯条251发出禁止车辆通行、第二灯条252发出准许车辆通行的信号指令为例，第一灯组231通常红灯亮起，第二灯组232通常绿灯亮起，此时，第一灯条251与第一灯组231相对应并亮起红灯以指示灯柱22第一侧22a车辆禁止通行，第二灯条252与第二灯组232相对应并发出绿光以指示灯柱22第二侧22b车辆准许通行；与实施例一相似，灯柱22第一侧22a的人行横道线1上及灯柱22第二侧22b的人行横道线1上均可设置第二发光件26，由于同一侧的车辆指示信号与行人指示信号通常为相反信号，即车辆准许通行时，行人禁止通行，因此，第一灯组231亮起红灯后，灯柱22第一侧22a的第二发光件26可与第一灯组231同步亮灯且发出绿光，第二灯组232发出绿光后，灯柱22第二侧22b的第二发光件26可与第二灯组232同步亮灯且发出红光，从而对行人及车辆同时起到指示作用，当然，第一发光件25、第二发光件26也可在出光的同时形成方向指示图案或倒计时动态图案等；由于各灯体亮度高，视觉宽，便于远离停车线车辆驾驶人员识辨灯光信号，亦便于靠近停车线车辆驾驶人员及货车后端跟行的车辆驾驶人员观察灯光信号，有效改善智能交通安全，由于在人行横道线1附近灯柱22上设置第一发光件25及在人行横道线1上设置第二发光件26，加强了车辆及行人的安全警觉，便于车辆驾驶人员识别的同时，减少了交通安全事故，从而使得交通秩序更为稳定，人们的人身财产安全得到进一步保障。
在本实施例中，交通信号光源2可设置在路口用以对车辆驾驶人员进行指示，也可设置在路口用以对行人进行指示；第一灯组231及第二灯组232发出的信号指令种类可相同，亦可不同，例如第一灯组231为红黄绿灯交替出光，第二灯组232为红绿灯交替出光，或二者均为红绿灯交替出光；二者指示对象可相同，例如均用以对车辆驾驶人员进行指示，其指示对象亦可不同，例如其中一个用以对车辆驾驶人员进行指示，另一个用以对行人进行指示。
实施例三
下面结合附图1及附图4仅就与前述实施例中不同之处作详细说明。
在本实施例中，作为进一步优化，灯柱22可分为设置在底座21上的立柱221和连接在立柱221上的横杆222，信号灯壳架24用于将信号灯组23固定在上述横杆222上，信号灯组23可为至少一个，且信号灯壳架24与信号灯组23一一对应设置；在本实施例中，作为进一步优化，每一信号灯壳架24上均设置有用于与对应的信号灯组23发出相同信号指令的第三发光件27，信号控制机与第三发光件27电连接，这样，信号灯壳架24亦可起到一定的警示作用，便于车辆驾驶人员及行人进行识别。
需要说明的是，当横杆222上的至少一个信号灯组23同一时间发出的信号指令相同时，立柱221、横杆222上均可设置第一发光件25，该第一发光件25能够发出与所有信号灯组23相同的信号指令；然而，当横杆222上的至少一个信号灯组23同一时间发出的信号指令不同时，可于横杆222和立柱221上分别设置能够发出互不相同信号指令的发光件；具体地，请参阅图4，若横杆222上设置有三个信号灯组23，从左到右依次为待左转车辆信号灯组L3、待直行车辆信号灯组L2和待右转车辆信号灯组L1，此时，连接在待左转车辆信号灯组L3上的信号灯壳架24中的第三发光件27可发出与待左转车辆信号灯组L3发出的信号指令相同的信号指令，连接在待直行车辆信号灯组L2上的信号灯壳架24中的第三发光件27可发出与待直行车辆信号灯组L2发出的信号指令相同的信号指令，连接在待右转车辆信号灯组L1的信号灯壳架24中的第三发光件27可发出与待右转车辆信号灯组L1发出的信号指令相同的信号指令；同时，该交通信号光源2的灯柱22上的第一发光件25设置方式可分为以下两种：第一种，本实施例的立柱221上可设置有用于与对应的待直行车辆信号灯组L2发出相同信号指令的第一发光件25，横杆222上设置有用于与对应的待左转车辆信号灯组L3发出相同信号指令的第一发光件25，具体地，横杆222上的第一发光件25可为多个且多个第一发光件25间隔设置在横杆222上，当横杆222上的第一发光件25指示指令为禁止通行时，多个第一发光件25同时亮起红灯；当横杆222上的第一发光件25指示指令为准许通行时，多个第一发光件25同时发出绿光，当然，横杆222上的多个第一发光件25也可从右至左逐序发出绿光以形成“可向左通行”的动态指示效果；第二种，横杆222上的第一发光件25也可布置为加装在横杆222左侧的第一延伸臂223上，该情况下的第一发光件25仅与待左转车辆信号灯组L3发出相同信号指令，而整个立柱221、横杆222上设置的第一发光件25均与待直行车辆信号灯组L2发出相同信号指令，第一延伸臂223上的第一发光件25设置形式可与前文中设置在横杆222上的第一发光件25类似，此处不作赘述；需要说明的是，根据交通法则及实际交通设施布置情况得知，一般待右转车辆不设灯，因违反交通规则发生事故的概率较小，故交通信号光源2可不针对待右转车辆指示灯作信号加强处理，但根据实际需求，横杆222右侧也可加装第二延伸臂（图未示）并布置类似上文的第一发光件25以向待右转车辆发出信号指令，此处，第一延伸臂223和第二延伸臂的截面形状均可为圆形、方形或菱形，此处不作唯一限定。
在本实施例中，作为进一步优化，信号控制机包括用于使信号灯组23、第一发光件25、第二发光件26以及第三发光件27同时发出信号指令的同步驱动模块，通过设置同步驱动模块，以实现各灯体的实时同步控制。
在上述交通信号光源2工作时，以交通信号光源2的待左转车辆信号灯组L3发出禁止通行的信号指令为例，待左转车辆信号灯组L3通常亮起红灯，此时，横杆222或第一延伸臂223上的第一发光件25、对应的信号灯壳架24上的第三发光件27可同时跟随待左转车辆信号灯组L3出光并发出相同信号指令，即信号灯组23亮起红灯后，第一发光件25、第三发光件27可同步亮起红灯，从而警示车辆此车道禁止左转，当然，第一发光件25、第三发光件27也可在出光的同时形成方向指示图案或倒计时动态图案等；由于各灯体亮度高，视觉宽，便于远离停车线车辆驾驶人员识辨灯光信号，亦便于靠近停车线拥挤车辆驾驶人员及货车后端跟行的车辆驾驶人员观察灯光信号，有效改善智能交通安全，由于在人行横道线1附近灯柱22上设置第一发光件25以及在信号灯壳架24上设置第二发光件26，加强了车辆及行人的安全警觉，便于车辆驾驶人员识别的同时，减少了交通安全事故，从而使得交通秩序更为稳定，人们的人身财产安全得到进一步保障；该交通信号光源2及发光件有效提高智能交通运行，为智慧城市增添亮丽景观。
显然，本实用新型的上述实施例仅仅是为了清楚说明本实用新型所作的举例，而并非是对本实用新型的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型权利要求的保护范围之内。
