照明燈具是市政道路照明燈具的關鍵構成部分，也是展現一個大城市智慧化水準及文化品味的關鍵媒介。道路路燈，像大白天一道美麗的景色線，裝飾著大城市；夜裡，接送大家的人身安全。由此可見LED路燈針對當代城市照明燈具的必要性！
道路路燈鏡片是道路路燈不可或缺的配件，它不但能夠聚光鏡散光眼燈源，使光源在室內空間上面有規律性、可控性地遍佈，還能夠極致地防止光的消耗，進而提升 太陽能的使用率。優秀的道路路燈攝像鏡頭還可以降低炫光，讓光源更溫和。可是你對LED路燈攝像鏡頭掌握是多少？
1)道路路燈攝像鏡頭的光點挑選
LED照明常見的光點就是指被照明燈具物件上產生的光(一般是豎直情況)。依據不一樣場地的燈光設計規定，必須設定不一樣的光點。因此 LED通常必須根據鏡片、反射鏡片等輔助光學系統設計製作。依據led和搭配鏡片的搭配，會產生不一樣的圖案設計，如環形光點、橢圓型光點和矩形框光點。
現階段矩形框光點(蜘蛛翼)主要是LED路燈的要求。矩形框光點聚光鏡工作能力強。聚光鏡後，光源勻稱地直射在地面上，使光源獲得更多方面的運用。一般用以轎車行車的路面上，備受客戶鍾愛。
2)道路路燈攝像鏡頭視角規格型號
不一樣的即時路況對電子光學有不一樣的規定。例如高速路、主幹路、主幹路、環路、院落區等不一樣的道路路燈高寬比。，應考慮到不一樣規格型號的視角，並挑選適合的視角以考慮過路人的照明燈具要求。
道路路燈有兩個視角。這一描述並不是指“0-180度”，只是指由“0-180度”構成的半平面圖；“90-270度”就是指由“90-270度”構成的半平面圖。
3)道路路燈鏡片原材料
道路路燈常見的原材料有夾層玻璃鏡片、電子光學級PC鏡片、PMMA級PMMA鏡片。
關鍵用以COB燈源，透光度一般為92-94%，耐熱500℃。因為其耐熱、高穿透力等特性，能夠自主挑選電子光學主要參數，但其品質大、易破的特性也限定了其運用範疇。
電子光學級PC攝像鏡頭：
關鍵用以SMD燈源，透光度88-92%，耐熱120℃。
電子光學級PMMA鏡片：
關鍵用以SMD燈源，一般透光度92-94%，耐熱70℃。
新型材料PC鏡片和PMMA眼鏡片全是電子光學塑膠材料，能夠根據塑膠和擠壓加工。商品生產製造高效率，原材料低成本。一旦交付使用，他們顯示資訊出明顯的銷售市場優點。

LED street light is an important part of road lighting, also shows a city’s level of modernization and cultural taste. During the day, the street lights are like a beautiful landscape, lighting up the city; at night, street lights escort the safety of people’s lives and property.It can be seen that led street light are of great significance to modern urban lighting!
Lens is an indispensable accessory for street lights. It can not only gather divergent light sources together, so that light can be distributed in a regular and controllable way in space, but also perfectly avoid light waste so as to improve light energy utilization rate. High quality street light lens can also reduce glare and make the light softer.But do you know anything about LED street light lens?
1)
The term “facula” in LED lighting refers to the pattern of light on the object (usually in a vertical state). According to the lighting design requirements of different sites, there will be different lighting requirements. Therefore, LED often needs to go through lens, reflective hood and other secondary optical design to achieve the design effect. Depending on the combination of LED and matching lens, there will be different patterns, such as round spot, oval spot and rectangular spot.
At present, the rectangular light spot (bat wing) is mainly required for led highway light. The rectangular light spot has a strong ability to concentrate light, and the light after the concentrated light shines uniformly on the road, so that the light can be used to a large extent. It is generally used in the road of motor vehicles, and is deeply loved by customers.
2)
Different roads require different optical requirements. For example, in the expressway, trunk road, trunk road, branch road, courtyard district and other places, different angles should be considered to meet the light needs of the passing crowd.
Street lights have two angles.”0-180″does not mean “0 to 180 degrees”,but the half plane of “0 and 180 degrees”.”90-270″represents the half plane of “90 and 270 degrees”.

Common street lamp lens materials are glass lens,optical PC lens and optical PMMA lens.
Glass lens, mainly used for COB light source, its transmittance is generally 92-94%, high temperature resistance 500℃.
Due to its high temperature resistance and high penetrability, optical parameters can be selected by oneself, but its large quality and fragile also make its use scope limited.
Optical PC lens, mainly used for SMD light source, its transmittance is generally between 88-92%, temperature resistance 120℃.
Optical PMMA lens, mainly used for SMD light source, its transmittance is generally 92-94%, temperature resistance 70℃.
New materials PC lens and PMMA lens, both of which are optical plastic materials, can be molded through plastic and extrusion, with high productivity and low material cost. Once used, they show significant advantages in the market.
Above some basic knowledge about LED street light lens, hope to help you understand the LED street lamp！
