DLC LUNA: Energy Savings Meets Reduced Light Pollution

设计照明联盟的最新倡议使黑暗天空友好的户外照明更接近主流. Happily, 克里族照明 has a deep bench of products that make the cut right out of the box.

In 1988, 两位关注美国上空快速消失的夜空的天文学家成立了国际夜空协会(IDA)。. IDA的使命是:“通过高质量的户外照明来保存和保护夜间环境和我们的黑暗天空遗产."  Even as the problem of light pollution has worsened over the last 35 years, 国际开发协会的议程缓慢但肯定地获得了公众和政策制定者的认可. 仍然, 保留黑暗的天空通常只被志同道合的客户所接受，他们愿意将这些做法纳入他们的照明设计和预算中.

这种情况现在可能会改变, 设计照明联盟(DLC)正在大力支持IDA的建议，以保护和恢复夜空，并在2022年第一季度推出 LUNA十大赌博信誉的平台要求V1.0.  DLC的SSL合格全国十大赌博官网清单(QPL)已经成为确定LED灯具是否有资格获得能源回扣的参考. Even when rebates aren’t available, QPL已成为快速寻找高效商用LED照明全国十大赌博官网的默认手段. 撰写本文时, 固态照明的QPL是第5版:SSL十大赌博信誉的平台要求第5版.1.

与此同时, public awareness and concern over light pollution continues to grow, along with the number of lighting ordinances designed to curb it.  这个不断发展的运动, as well as the continued demand for energy-efficient products, leads the DLC to predict robust participation in the LUNA qualification by the end of 2022. 

Five Principles of Responsible 户外照明

How Does the DLC Position 卢娜Versus the SSL QPL?

The DCL describes the LUNA十大赌博信誉的平台要求V1.0 as 补充 existing DLC requirements for outdoor lighting. LUNA-qualified products must first meet the existing DLC SSL V5.1 requirements for lighting efficiency and quality, 然后必须满足额外的标准，以帮助限制光污染，如天光和光侵入. 此外，LUNA要求使用暖白光- 2200K至3000K CCT.

用DLC自己的话来说:

卢娜V. 1.0寻求 建立户外照明的性能规格和最佳实践，目标如下:

1. 尽量减少照明能源的使用. In addition to meeting the efficacy thresholds of the DLC’s SSL V5.1十大赌博信誉的平台要求, LUNA qualified products must meet additional dimming, 控制, and shielding requirements to ensure efficient use of lighting energy. 这些阈值将帮助能效项目达到或超过其节能目标，并帮助最终用户降低运营成本.

2. 尽量减少光污染. The LUNA program introduces requirements for light distribution, correlated color temperature (CCT), and dimming 控制s that ensure less light is scattered into the atmosphere, resulting in reduction of light trespass and sky glow, 更暗的天空适合观星者, 天文学家, 和野生动物.

3. Provide appropriate visibility for people. The LUNA program incorporates all SSL V5.1 .光谱质量要求, BUG报告要求, 以及附加的光谱功率分布和强度分布报告要求, 使照明装置符合建议的做法和自愿指南的黑暗天空最佳做法.

一个条件就可以统治所有人

而不是引入与其他组织发布的现有指导方针竞争或冲突的标准, DLC构建了LUNA要求，使合格的灯具也符合IDA-IES模型照明条例(MLO)。, 一个立法模板，旨在使社区在制定黑暗天空条例时不必重新发明轮子. MLO是由国际黑暗天空协会(IDA)和照明工程学会(IES)于2011年联合开发的，并于2020年进行了更新.

LUNA qualification satisfies other third parties as well. LUNA全国十大赌博官网可以满足LEED认证的光污染和非法侵入要求, 使用2700K至3000K CCT的LUNA全国十大赌博官网可以满足2021年WELL认证的光污染和侵入要求.

LUNA和控制

LUNA products must be dimming capable – in particular, continuously dimmable to 20% or less of maximum light output. The DLC’s reasoning is that whenever an outdoor luminaire is dimmed, 无论如何, 天空辉光减弱. This is true even for zero-uplight luminaires, since dimming lessens reflections from the ground and other surfaces. Dimming can also mitigate light trespass, overlighting and wasted energy.

While the ability to dim the luminaire is a must, a standard 控制 receptacle is not – at least, 没有. 但它很可能即将到来. The SSL QPL already provides details about a product’s 控制lability and communication, and because dark-sky ordinances are proliferating rapidly throughout the world, DLC进一步说明，安装带有标准化控制插座的可控全国十大赌博官网可以降低过时的风险.

在范围内，在范围外

出于各种原因, several categories of outdoor products are currently excluded from the LUNA requirement:

• 洪水lights, replacement lamps and retrofit kits are excluded because these products are highly dependent on project design and installation, and efforts to mitigate light pollution must be addressed on a project-by-project basis.
• Luminaires for parking garages, stairwells/passageways and tunnels 是否不包括，因为照明通常被安装照明的结构所阻挡和包含.
• 非白人的光 是否超出了LUNA最初发布的范围，因为标准化指标仍在开发中. (特别是, this would include 克里族照明’s Turtle-Friendly Luminaires, which produce amber light below 2200K.)

因为满足LUNA要求会降低某些全国十大赌博官网(如护柱)的功效, 这些类型灯具的SSL QPL合格阈值正在进行调整以进行补偿.

这一切对市场意味着什么

The DLC expects LUNA十大赌博信誉的平台要求V1.0 to drive certain changes to lighting products and specifications. 我们可能会看到更多装饰性的道路和区域灯具，它们的光量较少，以满足U2或更低的初始LUNA要求.  Based on LUNA spectral and efficacy requirements, 我们也可以期待看到更多的室外灯具，CCT为2200K至2700K，每瓦105流明或更高.

Because LUNA offers a compensatory allowance for the drop in efficacy created by shielding, more shielded products are expected to make the QPL. DLC预测，将会有更多公开共享的灯具光谱数据，更多的努力将白色和琥珀色光谱的户外色度规格标准化.

现在, 根据DLC, 大多数QPL道路和区域灯具在3000K CCT下至少有一个版本的照明等级为U0或U1. LUNA qualification is expected to present the greatest challenge to decorative products and 护柱, even with the efficacy allowance.

克里族照明 全国十大赌博官网 Are Part of the Solution

您可能不会感到惊讶的是，Cree照明已经提供了符合LUNA规格的全国十大赌博官网多年, such as the RSW Series 街light introduced in 2016. 事实上, most 克里族照明 outdoor product lines for street, 道路和区域照明包括3000K或更低的CCT选项，满足LUNA要求. 查看我们的 LED bollard lights and pathway options to see how 克里族照明 can brighten up your walkways.

杜安亨德森, 克里族照明’s Lead Lighting Educator, notes that LUNA does not replace the value of lighting design, 而是对它的补充.

亨德森州, “While LUNA gets more products installed to help reduce light pollution, it doesn’t replace the value of lighting design. 良好的照明设计验证了可以长期维持的最低照明要求, 数值光学控制, reduces waste and minimizes risk. 照明设计过程应包括灯具实际定义的应用或系统寿命,000 hours is common for non-commodity products, as well as a product-specific lumen depreciation value at that defined application life. When this value is incorporated into a lighting design, it will give preference to products that lose less light over time, meaning applications are not being dramatically overlit on night one, 并且在使用早期不必要地产生更多的光污染.”

最后，亨德森认为，转向更负责任的户外照明是一个持久的变化. 作为行业利益相关者, 包括最终用户, are exposed to the conversation regarding the negative effects of light pollution, everyone wants to do the right thing. 我们已经很好地定位在这里在Cree照明与许多全国十大赌博官网，可以帮助相当长的一段时间. It’s exciting because as this shift continues to occur, we’ll be assisting our customers in achieving economic and energy goals, while influencing the night sky we all share in a positive way.”
