- Lamp efficacy
Lamp efficacy
By switching from Chalice 190 H to Chalice190 LED, power consumption has been reduced by 50-70 per cent, while the advanced LED system has either maintained or increased light output. This equates to sigificantly improved energy efficiency and performance.
- Ballast classification
Ballast classification
Controlling the electricity supply to the lamp (Energy Efficiency Index).
- Luminaire distribution
Luminaire distribution
Good levels of vertical illuminance provide light onto walls and the front of bookcases resulting in a bright welcoming space and allowing book titles to be read easily.
- System efficacy
System efficacy
Optical and thermal control within the luminaire are essential as even two lanterns of the same LED can have a widely differing light output ratio (LOR), lifetime and colour performance. Chalice 190 LED’s good luminaire design achieves a strong LOR and minimises light loss.
- 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
Lighting task areas with the correct amount of light.
- Zoning of lighting
Zoning of lighting
Lighting is zoned according to area use.
- Maintenance schedule
Maintenance schedule
With a 50,000-hour lifetime (@L70, Ta 25˚c), Chalice 190 LED minimises loss of light over time. In turn, the frequency of maintenance and the number of luminaires required to maintain lighting levels over the years are kept to a minimum.
- Waste light
Waste light
Eliminating waste light which does not hit the intended target.
- 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.
置换原Chalice 190后，光照度提高40%，能源消耗降低50%
约灵图书馆位于丹麦约灵(Hjørring)市中心的Metropol购物中心，其建筑结构的设计旨在吸引各年龄段的读者，极具启发性。图书馆内分为：生机盎然的儿童区，设有阅读树和摆满书籍的“鱼池”；潮流感十足的青少年区，配有巨大的“泡泡座椅”；精致优雅的成年区，装饰有植物、红褐色木家具和阅读灯。
图书馆原本安装的是250 盏Chalice 190 H紧凑型荧光射灯。但2012年推出Chalice 190 LED后，意味着传统的TC-DEL射灯有了首个“真正”被动冷却替代方案。Chalice 190 LED在产品尺寸、天花板开孔尺寸和连接件方面与此前型号相同，因而便于安装，而能源消耗降低70%，成为照明翻新领域一个成功的商业案例。
Chalice 190 LED的优点还在于防止组件过热的被动冷却技术；它有效降低了故障率，保持良好性能。带有突破性纹理涂层的计算机建模反射器设计使显色性高于 80，符合EN12464-1标准，同时它还提高了垂直照度。
安装商和客户的正面反馈
来自约灵照明安装商——El-Teknik的Jesper Madsen评论道：“为了降低能源消耗，我们需要新型照明，并由此节省能源相关的成本。我们的最低要求是要维持此前的照明水平；然而实际上，翻新后照度却得到了提高。原来安装的是Chalice射灯。改装Chalice LED提供了一项快捷的照明解决方案，同时射灯的安装成本也有所削减。”
来自约灵图书馆的Erik Østergaard评论道：“目前，对于新的照明灯，我只有赞美之辞。走廊变亮了，咖啡厅区域也因亮度提升而比以往更具魅力，更让人心情愉悦。”
