12w 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.
Sono stati creati diversi design che incorporano vari tipi di LED in una lampada. La tendenza attuale è quella di utilizzare LED ad alta potenza da 1 watt, ma alcune aziende utilizzano LED a bassa potenza nei loro prodotti, inclusi diversi LED a bassa potenza imballati insieme per svolgere lo stesso scopo di un singolo LED ad alta potenza. La forma dell'illuminazione stradale a LED dipende da diversi fattori, tra cui la configurazione dei LED, il dissipatore di calore utilizzato con i LED e le preferenze di design estetico.
I dissipatori di calore per i lampioni a LED sono simili nel design ai dissipatori di calore utilizzati per raffreddare altri dispositivi elettronici come i computer. I dissipatori di calore tendono ad avere quante più scanalature possibili per facilitare il flusso di aria calda lontano dai LED. L'area di scambio termico influenzerà direttamente la durata della luce stradale a LED.
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.
A drawback of LED focus panels is that most light is directed to the road and less light to the footpaths and other areas. This can be addressed by the use of specialized lens design and adjustable mounting spigots.
Energy Efficiency
The primary appeal of LED street lighting is energy efficiency compared to incandescent bulbs of the same luminance. Research continues to improve the efficiency of newer models. One such advance can be found in a street light product created by Lighting Science Group Corporation. One model of LED street lights produced by this group is up to 60 percent more efficient than previous models, lasts for 12 years, and allows for cost recovery through energy savings in only three years.
Un lampione a LED basato su un'uscita LED da 901 milliwatt può normalmente produrre la stessa quantità di (o superiore) luminanza di una luce tradizionale, ma richiede solo la metà del consumo energetico.
Poiché gli apparecchi di illuminazione a LED normalmente producono meno illuminazione lumen / Watt, è molto cruciale avere uno schema di illuminazione ben distribuito per svolgere lo stesso lavoro degli apparecchi convenzionali lumen / Watt più elevati. Quindi un buon design di lampioni a LED è quello di puntare diversi LED in un dispositivo verso diversi punti target.
Vantaggi della lampadina a LED da 12w
1. Basso consumo energetico e durata lunga e prevedibile.
2. La durata dei lampioni a LED è di solito da 10 a 15 anni, tre volte la durata delle attuali tecnologie adottate. I LED hanno anche un basso costo di manutenzione.
3. Oscuramento
LEDs can be dimmed when less street lighting is needed, such as late nights and early mornings.
4. Small package size.
5. More accurate color rendering
The color rendering index is the ability of a light source to correctly reproduce the colors of the objects in comparison to an ideal light source.
6. Quick turn on and off
Unlike fluorescent bulbs, which take time to heat up once switched on, LEDs turn on instantly and do not have a problem restarting immediately after being turned off (hot ignition).
7. RoHS compliance
8. LEDs don't contain Hg/Pb and don't emit poisonous gases.
9. Less attractive to nocturnal insects
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. Maggiore resa luminosa anche a basse temperature.
