Natural sunlight for buildings in Singapore; Combining nature, go green objectives and design

We are excited to share about this great project that we came across in This project is done by a Spanish architect and is situation in Mexico, where it is also as hot as Singapore at times.

This project intrigues us deeply by providing a break through in our perspective on the high level of design architecture we can achieve with natural sunlight.

In Singapore, our new buildings that comply with Greenmark standards usually have a high degree of using natural sunlight and ventilation.


Increasingly, we are also seeing these buildings moving towards the same likeness in many ways, for example;

1. High ceiling for level 1
2. Large openings at the side of buildings to allow air and sunlight to flow through and.
3. Probably a sunroof where sunlight can permeate through the glass.

Some examples of such would be Star Vista, Khoo Teck Puat Hospital, Our Tampines Hub, Heartbeat@Bedok and more. Notwithstanding our excitement and pride of having such developments in Singapore; we thought that this project we are sharing offers a fresh perspective to utilising natural sunlight to illuminate a place.

By doing this;
1. Calculating sunlight direction and scale
2. Channelling sunlight through a channel
3. Projecting sunlight to a coloured base
4. Making use of reflection theories to illuminate the place with myraid of colour

All of which, the source of sunlight is renewable, the channel is an old concept used in many applications like a submarine above-sea scope, the coloured base is an affordable and highly changeable set up, reflection of light is just plain old physics theory.

Question is; Do we need to spend a great effort to design a building and its structure to achieve Green mark objectives while having a design you can claim unique to the landscape?

This project clearly shows us that relying on basic physics principles we learnt in O'level may just suffice!

Using UV LED lighting to kill germs bacteria!

Before we thought LEDS are only manufactured semiconductor devices. But, today we realised that LED lighting can actually be grown !

Using different materials, researchers have shown that different LEDs can achieve different wavelengths of light. Through which, we can have different application. Furthermore, Roberto Myers, a materials scientist at Ohio State University in Columbus, and his team has developed LED nanowires on a thin aluminium foil. This invention not only allow UV lighting to be generated, but also takes care of heat dissipation from the LED.

For example, a UV LED lighting made of aluminium gallium nitride is able to kill germs and bacteria in water. Combining this invention with a water filtration system, it may be usefully applied in different places to produce clean portable water.

Using natural body heat or temperature to light up LEDs

Many students these days are experimenting with peizo-electric theory to generate electricity and lighting things up. Combining this theory with the seeback effect, LED lighting is made possible.

Selecting the right type of material that will generate a charge due to temperature difference is critical in lighting up an LEDs.

The amazing thing about LED is the low voltage and current required to light up. This really enable many different applications and electrical generating methods to be applied.

E.g an awesome student in Canada using body heat to light up a torch light. All these without a need for battery.


This might just replace solar panels or be an additional arsenal towards our go-green campaign. This form or renewal energy is both free (from the body heat point of view) and seemingly perpetual.

Stretchable LED Lighting? | Events and Electronics

If lightings can be stretched, how do you think we can enhance our spaces and minimise / reduce lighting costs?

Putting mechanical engineering considerations aside for now? We probably can explore the following;

1. LED Lightings as visual displays for smart clothing
2. LED Lighting for curve screens in Smart Phones
3. Smart LED Lighting for architectural facade (indoor / outdoor ("although challenging it may be"))
4. LED Lighting displays covering different surface area when necessary for advertising and creative industry.

By bringing mechanical engineering considerations in lighting, we might need to explore the following;
1. Stretchable host material for the LEDs where it is both conductive and insulated from touch.
2. Types of material for the LEDs that is able to light up with movable conductive electrical supply

It never fails to amaze us how a well planned architecture that includes the understanding and usage of natural lighting results in a splendid finish.

Engaging and utilising natural lighting not only reduces the electricity and carbon consumption; more importantly it brings us, the people living within closer to nature once more.

Let us share projects which we thought are really great through careful understanding and adoption of natural lighting.

Exploring different perpetual everlasting light forms (bio-light)

From our daily exposure to all types of lightings (from designing lightings to lighting technology and applications to lighting fixtures and systems), we begun also to explore creation of light.

That made us explore natural wonders where nature itself (be in a bacteria to a deep sea creature to our physical human body) creates light. This concept or emitting light form has been termed as BIO-LIGHT.

Powering lights through electricity has always been a common knowledge to us as the only way of doing it. But what it if it can be powered by living organism?

Bioluminescent light is a new concept of powering light through living organism, like fireflies, being explored by Philips. It emits out low voltage lighting that is suitable for ambience lighting or signage in the dark.

Due to its low lumen output, it is not meant to compete in the same market as LED or other light source. But, it possesses the same energy saving quality as to LED. Further, it does not require electricity to power them; it feeds on methane and composed material to sustain life, hence the continuous generation of lighting. Being just a living organism, I suppose that it can take up various form and sizes, making it versatile in many other environment, like becoming a road marking at night or lights in dark places like theatre or cinema. 

Currently the life span of the bacteria or other light emitting organisms are limited to days, but scientist is working to extend the life span to months, making it more realistic for use.

Using bioluminescent light, in my opinion could bring about a new design for indoor lighting as it is unique and have no restriction in shapes. It could be more of a complement to LED lighting design or traditional light. 

However, such bio-light would lack the “smartness” of the future connected lighting and the dimming control as one would desired and compared to LED.

At this stage, I believe it would be much more expensive to install and conceptualize.

Is circadian lighting design necessary?

Indoor lighting is always a critical component for all types of buildings. Recent trends of green building brings forward designs that utilises windows, sun roof or even large openings where natural sunlight can reach inside a building easily.

While this green movement serves to conserve lighting energy, it also directly benefits the people working within the building by exposing them to natural lighting. We can then explore the concept of cicadian lighting systems; the pros and cons of natural lighting to our body biological system.

Following the sun set and sun rise cycle, the natural light emitted from the sun varies in intensity and color temperature and we may have very strong dependency with the sun cycle. Circadian lighting design is meant to simulate the intensity and color temperature of the sun cycle to promote productivity at work and a relax atmosphere reaching the end of the day.

To achieve the respective intensity and color temperature, lighting industry have come out with tunable white LED where it can produce various color temperature via dimming of intensity and a control system that is capable of changing the intensity at real time. This is still a relatively new concept as the science and lighting technology have not yet merged together completely but companies in the United States are getting them installed improve productivity.

I feel that it would be necessary for circadian lighting design to advance further. With the flexibility and stability of LED lighting technology, there is the potential to provide more lighting design to benefit our human body and internal body clock. Gradually, the benefits may encourage more research into a better tunable bulb or white LED that have a wider and precise range for the color temperature.

Laser diodes - The next wave of LED lighting development?

Laser diodes to be the next LED lighting development - Is this possible and how feasible it is to our real life general lighting application?

Theoretically, if we place 2 mirrors on each side of the LED, the wide beam light throw effect from the LED will be forced to reflect internally within the 2 mirrors resulting in a more focused light beam.

This might mean that we need to create a light path for the LED in order to achieve the effect. This would be similar then to using fiber optic as a light guide.

All in all, can lasers replace LED Lighting? In my own opinion, i doubt so as general lighting requires a wide coverage at the lowest possible power input. Lasers will not be able to achieve an even wide coverage.

Project Lorong Halus wetlands - Outdoor lightings

Correct lighting techniques is extremely important when it comes to lighting up places like Lorong Halus Wetland where it can get very dim after sunset. 

Being the chosen lighting company by PUB, Singapore’s National Water Agency to light up Lorong Halus Wetland, we are extremely honoured to be recognised in our expertise in LED lighting technology and architectural design. In this project, we aimed to not only bring out the serenity and beauty of the reservoir but also create a flair of mystery liviness as night falls. 

With our landscape spotlights selectively placed in a desired angled it is able to create a balance and tailored lighting effect, evoking a sense of elegance and beauty to the reservoir overall atmosphere.

Our spot lights are not only quality assured but it is able to adjust to the correct lighting techniques to highlight the features and create the perfect amount of drama in the outdoor spaces but also energy-efficient, pocky friendly and definitely kinder to the planet.

With that, we also hope if we can also support your outdoor lightings at an extremely affordable price.

Tip for exterior lighting: A garden with appropriate lighting can often discouraged trespassers or thieves from entering or tempering with the property.
