Take Me Home, LED Street Light
LED Street light can be regarded as semiconductor light which is of high efficiency. LED Street light can glow based on the weak electricity since it has a solid-state light source. Well, the weak electricity is from the semiconductor PN junction actually. Under a certain positive bias voltage and the electrical flow injection, the electron injected the hollow hole of P section and hollow hole of N section emit photon after spreading to active area and then compounding through radiation, changing electricity directly into light power. Different from traditional flood light, LED tube light is eco-friendly, energy saving and has lower power consumption.
An LED street light is an integrated light that takes light emitting diodes (LED) as its light source. It is considered integrated light because, generally, the luminaire and the fixture are not independent parts (except LED Gine-based luminaires). The LED tube cluster is tightened on a panel and then assembled to the LED panel with a radiator to shape an integrated lighting fixture.
Diverse designs have been created that incorporate various types of LED Street light into a light fixture. The current tendency is to use high power 1 watt LEDs, but some firms adopt low power LEDs in their products, covering several low power LEDs arranged together to generate the same effect as a single high power LED. The shape of the LED Street light relies on several elements, including LED configuration, the radiator used with the LEDs, and aesthetic design preference.
Radiators for LED street lights are analogous in design to heat sinks used to cool other electronics such as computers. In most cases, heat sinks tend to have as many grooves as possible to take the flow of hot air away from the LEDs. The range of heat conduction will immediately impact 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. An LED street light is considered to be at the end of its life once its brightness reduces by 30 percent.
Most LED street lights own a optical lens on the LED panel, which is aimed at casting its light in a rectangular pattern. It is an advantage compared to traditional street lights which typically have a reflector on the back side of a high-pressure sodium lamp. In this case much of the luminance of the light is lost and generates light pollution in the air and the surroundings. Such LED tube can also bring about glare for drivers and pedestrians.
