18w LED Street Light Bulb
An LED street light is an integrated light that uses LEDs as its light source. These are considered integrated lights because, in most cases, the luminaire and the fixture are not separate parts (except LEDGine-based luminaires). New in manufacturing, the LED light cluster is sealed on a panel and then assembled to the LED panel with a heat sink to become an integrated lighting fixture.
Different designs have been created that incorporate various types of LEDs into a light fixture. The current trend is to use high power 1 watt LEDs, but some companies use low power LEDs in their products, including several low power LEDs packed together to perform the same purpose as a single high power LED. The shape of the LED street light depends on several factors, including LED configuration, the heat sink used with the LEDs, and aesthetic design preference.
Heat sinks for LED street lights are similar in design to heat sinks used to cool other electronics such as computers. Heat sinks tend to have as many grooves as possible to facilitate the flow of hot air away from the LEDs. The area of heat exchange will directly affect the lifespan of the LED street light.
The lifespan of an LED street light is determined by its light output compared to its original design specification. Once its brightness decreases by 70 percent, an LED street light is considered to be at the end of its life.
Most LED street lights have a lens on the LED panel, which is designed to cast its light in a rectangular pattern, an advantage compared to traditional street lights, which typically have a reflector on the backside of a high-pressure sodium lamp. In this case, much of the luminance of the light is lost and produces light pollution in the air and surrounding environment. Such street lights can also cause glare for drivers and pedestrians.
Kelemahan panel fokus LED adalah bahawa kebanyakan cahaya diarahkan ke jalan dan kurang cahaya ke jalan kaki dan kawasan lain. Ini dapat ditangani dengan penggunaan reka bentuk lensa khusus dan spigot pemasangan yang boleh disesuaikan.
Kecekapan Tenaga
Daya tarikan utama lampu jalan LED adalah kecekapan tenaga berbanding dengan lampu pijar dengan pencahayaan yang sama. Penyelidikan terus meningkatkan kecekapan model yang lebih baru. Satu kemajuan seperti itu terdapat dalam produk lampu jalan yang dibuat oleh Lighting Science Group Corporation. Salah satu model lampu jalan LED yang dihasilkan oleh kumpulan ini adalah sehingga 60 peratus lebih cekap daripada model sebelumnya, tahan selama 12 tahun, dan memungkinkan pemulihan kos melalui penjimatan tenaga hanya dalam tiga tahun.
Lampu jalan LED berdasarkan LED output 901 milliwatt biasanya dapat menghasilkan jumlah cahaya (atau lebih tinggi) yang sama dengan lampu tradisional tetapi hanya memerlukan separuh penggunaan kuasa.
Oleh kerana lekapan lampu LED biasanya menghasilkan pencahayaan kurang lumen / Watt, sangat penting untuk mempunyai corak pencahayaan yang diedarkan dengan baik untuk melakukan pekerjaan yang sama dengan lekapan konvensional lumen / Watt yang lebih tinggi. Oleh itu, reka bentuk lampu jalan LED yang baik adalah menunjuk LED yang berbeza dalam satu lekapan ke titik sasaran yang berbeza.
Kelebihan Lampu Jalan LED 18w
1. Penggunaan kuasa yang rendah dan jangka hayat yang panjang dan boleh diramalkan.
2. Jangka hayat lampu jalan LED biasanya 10 hingga 15 tahun, tiga kali masa penggunaan teknologi semasa. LED juga mempunyai kos penyelenggaraan yang rendah.
3. Kelaparan
LED boleh dimalapkan apabila lampu jalan kurang diperlukan, seperti larut malam dan awal pagi.
4. Saiz pakej kecil.
5. rendering warna yang lebih tepat
Indeks rendering warna adalah kemampuan sumber cahaya untuk menghasilkan semula warna objek dengan betul berbanding dengan sumber cahaya yang ideal.
6. Hidupkan dan matikan pantas
Tidak seperti lampu pendarfluor, yang memerlukan masa untuk memanaskan setelah dihidupkan, LED menyala seketika dan tidak menghadapi masalah untuk dimulakan semula segera setelah dimatikan (pencucuhan panas).
7. Pematuhan RoHS
8. LED tidak mengandungi Hg / Pb dan tidak mengeluarkan gas beracun.
9. Kurang menarik bagi serangga pada waktu malam
Insects are sensitive to the UV-blue and green region of the light spectrum. Nocturnal insects are attracted to the emission of UV-blue and green light from conventional light sources. White LEDs, however, emit light in a small peak in the blue range and smaller in the green range, so nocturnal insects are less attracted to such light sources.
10. Easy to design non-glare lighting equipment
Most LED street lights have a lens on the LED panel, which is designed to cast its light in a rectangular pattern, an advantage compared to traditional street lights, which typically have a reflector on the backside of a high-pressure sodium lamp. In this case, much of the luminance of the light is lost and produces light pollution in the air and surrounding environment. Such street lights can also cause glare for drivers and pedestrians.
11. Higher light output even at low temperatures.
