design, light and life
Ternyata sudah lama tidak melakukan update di blog ini. Terakhir update di bulan Februari 2013 dan sudah 1 tahun blog ini ada :). Melawan kemalasan dan mencoba mendisiplinkan diri itu adalah sesuatu yang tidak mudah. Niat saja tidak cukup. Harapan saja juga dirasa kurang.
Just Do It!. Lakukan apa yang telah diniatkan. Jangan biasakan untuk menunda atau menunggu good-mood itu datang.
Think big, Start small and Act now.
Besok, 20 Februari 2013, adalah Hari-H pelaksanaan Kelas Inspirasi. Kebetulan saya akan mengajar di SDN Rawasari 02, Jakarta Pusat. Meskipun sekolah ini berada di tengah kota, namun kondisi sekolah amat sangat standar dan bahkan akses masuk ke sekolah hanya berupa gang kecil yang hanya cukup dilalui oleh 1 mobil.
Hari ini adalah H-1 menjelang Kelas Inspirasi pada 20 Februari 2013 besok. Sungguh suatu perasaan yang tidak jelas sedang berputar-putar di alam pikiran saya. Antara senang bisa berbagi dengan anak-anak SD Negeri, deg-degan karena ini kali pertaman mengajar anak-anak SD, nervous karena merasa persiapan kurang, dsb. Namun dibalik ini semua, muncul satu perasaan kagum dan hormat kepada para Guru Sekolah Dasar Negeri ini. Ternyata memang tidak mudah mengajar untuk anak-anak SD.
Orang tua saya adalah Guru Sekolah Dasar Negeri di Kabupaten Ngawi. Hanyalah Pegawai Negeri Sipil (PNS) biasa. Kami adalah keluarga Guru. Bapak, Ibu adalah Guru SD. Saudara-saudara Bapak dan Ibu juga banyak yang jadi Guru SD Negeri. Dan sudah sewajibnya saya bersyukur hidup dalam keluarga yang menjunjung tinggi pendidikan. Bapak dan Ibu hanya lulusan SPG. Cita-cita mereka sederhana, anak-anaknya harus sekolah setinggi-tingginya. Tidak hanya anak-anak kandungnya, tapi juga anak-anak didiknya. Alhamdulillah saya bisa menunaikan cita-cita mereka, bisa kuliah di PTN, dapat beasiswa dan bisa lulus kuliah.
Sudah saatnya bagi saya untuk berbagi dengan sesama. Jangan sampai anak-anak SDN ini patah semangat untuk memperoleh pendidikan setinggi-tingginya. Sungguh saat ini saya merasa dibukakan mata fisik dan mata hati saya.
Kelas Inspirasi hanyalah awal untuk memulai. Dan saya bersyukur bisa terlibat dan berpartisipasi di dalamnya. Semoga saya mampu mengemban amanah ini…. Bismillahirrahmanirrahim….
This photo was taken on November 21, 2012, at Pameran Pekan Kreatif Indonesia (Indonesia Creative Power exhibition) in Jakarta. My big question is why the Event Organizer put the yellowish lighting with bad color-rendering-index to be a general lighting at the exhibition? Are they don’t know or don’t care with the effect of bad lighting? Or they just simply put this lighting from their area or parking lot? 😀
This lighting using lamp from high-discharge lamp (sodium or SON lamp). This lamp has color-rendering-index (CRI) around 24. With this CRI, the characteristic of this lamp is can not reveal the real color from the object. Red color became grey, blue color became black, white color became yellow, etc. It will create bad-images and potential-loses for exhibitor and audiences. The product display will look dull and the audiences will feel bored when visit the booth.
Lighting with good CRI is essential to be used for highlight the product display, information, color chart, painting, fashion, furniture, materials, etc. That’s why when you make shopping you fill find that most of these shop lighting using high wattage lamp (metal halide or halogen) to get best CRI. Want to prove it? Just stay for a while under the lamps, and you will feel the hot air :D.
If you want to know more about CRI, you can learn from this link : http://en.wikipedia.org/wiki/Color_rendering_index
These photographs will show you the effect of lighting scene to the hospitality industry, specially for the hotel guest-room application. Simple & smart solution to make guest enjoy room more, to make them more relaxed, build their mood or perhaps helping guest feel like in their own room at home. Guest will easily set the lighting scene with control button that placed near their bed.
To avoid the “discotique” effect caused by too many lighting color applied, the hotel management (or perhaps lighting designer) carefully selected the lighting color for each room. The lighting intensity also can be controlled by dimming system, so it will not too bright or too dark, and all of effect will be controlled by Guest himself/herself, because they are the owner of this room 🙂

To get the most from solar panels, you need to point them in the direction that captures the most sun. Solar panels should always face true south if you are in the northern hemisphere, or true north if you are in the southern hemisphere. True north is not the same as magnetic north. If you are using a compass to orient your panels, you need to correct for the difference, which varies from place to place.
For solar panels to cost-effectively generate electricity for their owners, the panels need solar exposure between about 9 a.m. and 3 p.m. Owner has to make sure that there are no obstacles that reduce the capability of solar panel to catch the light or solar. Not all outdoor area is good for solar panels. There may be trees that cast too much shade on your parking area or street, for example. So please make sure that solar panel has enough solar to catch or produce become electricity and avoid mistakes happened from images below.
This linear arrangement of general lighting give a clean & modern look for this train station. Lighting aimed on area where passenger get in and get out from the train.

imaginary path lighting.

In manufacturing and design process, a mockup, or mock-up, is a scale or full-size model of a design or device, used for teaching, demonstration, design evaluation, promotion, and other purposes. A mockup is a prototype if it provides at least part of the functionality of a system and enables testing of a design. Mock-ups are used by designers mainly to acquire feedback from users.
In lighting project, mockup required to evaluate design that proposed by designer or consultant, to analyze the effect and in the end to get approval by consultant itself or by the customer or owner. Sometimes mockup required by consultant to compare the lighting solution proposed by each vendor or supplier, which one is passed the lighting-design requirement.
I love the sweet color saturation ring featuring in this modern switch by Philips Lighting and Philips design in collaboration with co designer Tom
