CUPO, sebuah utak-atik-gathuk

Mungkin awalnya bisa dianggap sebagai kegiatan iseng untuk mengisi akhir pekan atau untuk refreshing. Melubangi kertas dengan berbagai macam motif atau hiasan kemudian mewarnainya menggunakan cat poster dan disusun menurut urutan gradasi bentuk dan warnanya. Semakin sering membuat, semakin merasa nikmat. Kemudian mencoba merambah bentuk atau tulisan kaligrafi atau motif atau pattern. Untuk saat ini cat yang digunakan masih menggunakan cat poster yang mudah ketika digunakan dan ketika masih ada sisa banyak, bisa digunakan sebagai mainan anak-anak. Mainan yang sederhana, bermain kuas dan warna.

Almost perfect

  
Efek penggunaan lampu TL untuk aplikasi cove-lighting. Terlihat semburat cahaya tipis dan lurus yang saling bersinggungan (overlap) antar lampu TL. Almost perfect but still not perfect.

Solusi: dengan mengganti penggunaan lampu linear atau TL dengan lampu khusus aplikasi cove-lighting. Bisa juga menggunakan lampu jenis pita atau roll. Namun harus diperhatikan juga tingkat terang yang dihasilkan. Jangan sampai sebaran cahaya terlihat bagus di ceiling, namun membuat ruangan menjadi gelap.

Perspective

What you see in this image is just the matter of perspective. You (as user) will see and focus with the result, but for lighting designer or lighting engineer or lighting vendor will focus to find the way to light up the beauty of architectural detail. How to choose fixtures type, find the place to put the fixtures without sacrified the architectural look. So, please enjoy the beauty of monumental Cathedral of San Ildefonso, Mexico.

Penerangan Jalan Umum (PJU)

20130906-203512.jpg

Fungsi utama lampu Penerangan Jalan Umum (PJU) adalah memberikan pencahayaan buatan bagi pengguna jalan sehingga mereka merasa aman (safety) dalam melakukan aktivitas (berjalan, mengemudi, menyeberang). Pengemudi akan merasa aman karena bisa memperkirakan kondisi jalan sebelum melewatinya. Pejalan kaki bisa menyeberang dan berjalan tanpa takut akan tertabrak atau gangguan kriminalitas lainnya.

Kriteria distribusi cahaya PJU adalah sebaran cahaya yang melebar di sepanjang sisi jalan, sehingga kebutuhan jumlah PJU & tiang bisa optimal. Jarak antar tiang terlalu dekat maka investasi pengadaan juga tinggi, terlalu jauh akibatnya pencahayaan tidak optimal.

Yang terjadi pada foto diatas adalah salah kaprah dalam aplikasi PJU. Cahaya hanya berkumpul pada suatu area, tepatnya di sekitar tiang. Area diantara tiang juga gelap. Pejalan kaki juga akan merasa takut jika melewati jalan ini. Pengendara juga harus meningkatkan konsentrasi saat mengemudi. Yang paling dirugikan adalah konsumen yang membeli produk ini. Karena manfaat (benefit) yang mereka dapatkan atas investasi yang dilakukan (PJU) tidak maksimal, bahkan minimal. Biaya listrik tetap harus dibayarkan tanpa memperoleh manfaat distribusi cahaya yang benar.

Color-Rendering-Index (CRI)

20121125-092904.jpg

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

Guest room lighting at the hotel

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 🙂

Solar Panel installation mistakes

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.
