  • Lamp efficacy

    Lamp efficacy

    Ensuring the lamp efficiently converts electricity into light (lm/W).

  • Ballast classification

    Ballast classification

    Controlling the electricity supply to the lamp (Energy Efficiency Index).

  • Luminaire distribution

    Luminaire distribution

    Orus’ unique patented optic controls the light emission bending and shaping the light directly onto the road. Using only 35W version the light distribution in this example provides the perfect substitute for 250-400W traditional road lighting.

  • System efficacy

    System efficacy

    Combining optical and thermal control within the luminaire (luminaire lm/W).

  • Presence/absence detection

    Presence/absence detection

    Presence: Lights automatically turn on/off with movement. Absence: Lights automatically turn off and must be manually switched on.

  • Daylight detection

    Daylight detection

    Artificial lighting which responds to the natural light conditions.

  • Constant illuminance

    Constant illuminance

    A function designed to produce correct light levels for the duration of the maintenance period.

  • Task-scene setting

    Task-scene setting

    Allowing the user to set scenes and adapt the lighting to different tasks.

  • Timed off

    Timed off

    Automatic cut-off can be installed to turn all lights off during unoccupied hours.

  • Task lighting

    Task lighting

    Ensuring light is concentrated on the road provides the required high levels of illuminance while using minimal energy.

  • Zoning of lighting

    Zoning of lighting

    Lighting is zoned according to area use.

  • Maintenance schedule

    Maintenance schedule

    Maintenance must be performed in response to product age, performance and environment.

  • Waste light

    Waste light

    Orus’ FlatBeam technology helps to cast more than 93% luminous flux to the road. Precise optical control and luminaire aiming eliminates upward light and ensures no energy is wasted lighting the wrong area. By eliminating upward light, ecological disturbance is also minimised.

  • Reflectance

    Reflectance

    Taking advantage of light which is reflected from the surface within the space.

  • Visible smart metering

    Visible smart metering

    Results of actions can be quickly seen as increased or decreased energy use to encourage responsible energy consumption.

赤峰桥位于天津市中央商务区,横跨海河,是国内唯一座斜塔双索面弯斜拉桥。因其独特的造型而成为天津的地标。而因其充满动感的设计,赤峰桥在照明方面碰到了若干问题。包括灯具维护及更换光源的难度,较高的光污染及溢散光,较低的光线一致性及眩光的控制。显而易见的是,如果使用传统高杆形的大功率(250-400W)灯具,大桥将会显得比较杂乱。

低安装高度灯具提高了舒适性并便于日常维护

经过广泛的实地调查及对照明方案的展示,索恩照明的Orus灯具因其平光专利技术被确定为赤峰桥的照明方案

Orus配备特殊的双向对称光学系统,配光独特锐利,使光线横向地投射到路面上。使用一个35W的陶瓷金卤灯,光线均匀度良好,最低限度减少眩光,降低能耗。除此之外,Orus0.9米的安装高度确保对车辆不会产生直接的光线,同时安装维护及其容易。低安装高度也很好的衬托了大桥夸张的造型。

为了达到低维护的目的,Orus采用高质量的防破坏材质及工艺,确保较长的产品使用期限。配备电子镇流器提高了节能效果,延长了光源的使用寿命。

索恩照明照明一位设计师Michael提到:Orus为赤峰桥提供了理想的照明方案。除了独特的安装高度,优异的光学系统合良好的光线控制极大的优化了光源的效率。35W金卤光源的使用是提高光线控制,节能等性能水平的最佳选择。
