PROJECT OF LAMP - MOON FLOW

Often light gave a positive projection,while darkness project a negative type, yet its due to darkness light can cast out its brilliance. For gray it is a neutral color, a fizzy color between  white and black, it very essence is much like the moon; when shone upon it becomes brighter and corresponding it becomes darker.

DESIGNED IN 2011

STEP 1

PROJECT OF LAMP - SKETCH

STEP 1
Heading from the concept of the moon, I used concrete to imitate the moon's surface and uses lighting to achieve the likeness of the moon's reflection.

STEP 2
Using a thin ceramic plate to give an intimating blurry moonlight effect to the lamp cover, and combine it with a traditional form to bring the moonlight part of us.

STEP3
On the search for a new interpretation and material to use for the moonlight effect; I found Litracon which is a combination of concrete and optical fiber. This combination enable light to break through and tip the image of concrete been cold, and in doing this it created more freedom for imagination.

PROJECT OF LAMP - LITRACON

LiTraCon is the trademark for is a translucent concrete building material. The name is short for "light-transmitting concrete". The technical data sheet from the manufacturer says the material is made of 96% concrete and 4% by weight of optical fibers, it was developed in 2001 by Hungarian architect Áron Losonczi working with scientists at the Technical University of Budapest.

PROJECT OF LAMP - LITRACON

An optical fiber is a flexible, transparent fiber made of very pure glass (silica) not much wider than a human hair that acts as a waveguide, or "light pipe", to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communication. Fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so they can be used to carry images, thus allowing viewing in tight spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers.

An optical fiber junction box. The yellow cables are single mode fibers; the orange and blue cables are multi-mode fibers: 50/125 µm OM2 and 50/125 µm OM3 fibers respectively.
Optical fiber typically consists of a transparent core surrounded by a transparent cladding material with a lower index of refraction. Light is kept in the core by total internal reflection. This causes the fiber to act as a waveguide. Fibers that support many propagation paths or transverse modes are called multi-mode fibers (MMF), while those that only support a single mode are called single-mode fibers (SMF). Multi-mode fibers generally have a larger core diameter, and are used for short-distance communication links and for applications where high power must be transmitted. Single-mode fibers are used for most communication links longer than 1,050 meters (3,440 ft). Joining lengths of optical fiber is more complex than joining electrical wire or cable. The ends of the fibers must be carefully cleaved, and then spliced together either mechanically or by fusing them together with heat. Special optical fiber connectors for removable connections are also available.

LAW OF REFRACTION

1. The ratio of sines of the angles of incidence and refraction is a constant (Snell's Law) (The ratio is constant for a particular wavelength and a particular set of materials.)

2. The incident and refracted rays are on opposite sides of the normal at the point of incidence.
3. The incident ray, the normal, and the refracted ray are coplanar.

Snell's Law:

where n is a constant.

(the constant is the ratio of the speeds of light in the two media.)

PROJECT OF LAMP - PROCESS

CONCEPT
Through light mankind is able to expand their life into the night. Upon the subject of designing lighting, many designer have already explored into areas like; lifestyle, spirit, and between light and darkness, yet all this is a projection on how mankind looks at light.



STEP 01 - TEST MODEL

The first experiment is to make a sample model of Litracon, which was made up of a few simple frames with optical fibre in it. Through this I hope to find the possibility of transparency.

 

STEP 02 - MODEL 1
Model 1 was aimed to challenge the limit of transparent concrete; in which I construct a 12cm thickness just to see its transparency. Finally setting up the appropriate thickness for Litracon.

STEP 03 - MODEL 2
Model 2 was aimed in creating a larger surface area for the optical fibre. It is through the thin concrete wall and the huge amount of surface light that I hope to express the nature of transparent concrete, hence different type of thickness was created to ensure an accurate bind of optical fibre and concrete. The Thickness of Litracon was 0.8 cm.

STEP 04 - LED LIGHT
In the end two transparent concrete was created.To be able to finalize the project I had used steel as the base of the lamp, with it I meld it and fitted with LED light. Steel was chosen to be able to combine with the concrete characters.

PROJECT OF LAMP - MODEL 01

Through the analysis of trial and error, the Moon Flow was created. I have documented the process for future expansion on the material and the model of Litracon.



Litracon character was to let optical fibre be poured with concrete, in doing so the concrete would have the effect of light. Continue with optical fiber effect it can create a substantial thickness and still retain transparency.

PROJECT OF LAMP - MODEL 02

On model 2 there was crack due to poor resistance and through discussion two problem was found. The first been the concrete does not have enough resistance in structure, and the second was from the dense pact of optical fibre which let to the weakness of the concrete. In future Litracon would be modified to the characteristic of concrete.
