Along with the technological breakthrough 4.0, more and more high-quality and diverse lighting products are available, giving consumers more choices. One of the lighting devices that is increasingly popular in our lives is the LED light. So what is led street light?
In particular, on roads, campuses, hospitals, highways, bridges and roads, we often see led street lights. So:
- What is led street light?
- What types of LED street lights are there?
- Similarly, what are the applications of led street lights?
Why use led street lights?
Certainly, many of us have raised a lot of question on led street light? Understanding those concerns, in this article, HC Lighting would like to share with readers’ useful information about led street lights.
What is led street light?
Led street light is one of the products in the line of light-emitting diodes, used for public street lighting to help save energy when operating for a long time. An LED street light is a product with a light source emitted by a light emitting diode (LED) and is considered an integrated lamp.
What are the applications of led street lights?
This is a device used for public lighting. We can see led street lights anywhere: private roads or highways, bridges or highways, hospitals to schools, parks. street light? They meet all requirements with less hassle in terms of installation, lighting and efficiency in use.
They are available in different sizes according to needs and shapes. Their lifespan is longer than 12 years to reduce costs for the government, contributing to saving the state budget.
Types of led street lights
Currently, to meet the needs and purposes of use, there are many different types of led street lights. Classified by luminous capacity, there are high-voltage street lights: 30W, 50W, 100W, 150W, 200W. Let’s take a look at 3 popular high-pressure led street lights in 2019.
Why use led street lights?
Compared with traditional street lights, LED lights use low pressure, emit white light with low temperature, high productivity, long life, energy saving, safety, and environmental friendliness. Besides, LED street lights also own for themselves outstanding features and advantages such as:
Energy Efficiency of led street light
The main attraction of led light is the energy efficiency it offers compared to other traditional lights. An LED street light requires only half (or less) of the energy to produce the same light output (or more) of a traditional light bulb. In addition, LEDs do not go out completely, only reducing light output until they need to be replaced, unlike traditional lights.
Long and predictable lifespan: The predicted lifespan of LED street lights is typically 10 to 15 years. The operating time of the LED device is limited by other electronic devices such as the amplifier, which has a lifespan of about 50,000 hours). In fact, using LEDs longer life and durability means lower maintenance costs.
More accurate color rendering with led street light?
Color rendering (CRI) is the ability of a light source to accurately reproduce the colors of objects compared to an ideal light source. led street light? The higher the color rendering, the clearer the vision will be.
Quick on and off: Unlike HID, fluorescent, and high pressure lamps, such as mercury vapor, metal halide, and sodium vapor lamps, which need time to warm up after turning on, The LED light comes on immediately.
Less attractive to insects at night: Nocturnal insects are attracted to ultraviolet light emitted by many common light sources.
What is led street light means Optical efficiency?
Other street lights must use reflectors to reflect the omnidirectional light emitted by the bulb. Even when operating in the best conditions, reflectors still absorb some light. Similar to fluorescent lamps and other lamps coated with phosphorus, the lamp is also absorbed by the reflectors.
What is led street light? The LED luminaire can completely transmit in the desired direction without reflection.
What are the disadvantages of led street lights?
– One of the bad effects of led lights in general and led street lights in particular is the effect on health, affecting our eyes when we are improperly exposed. Many studies have shown that long-term exposure to white light LED street lights can cause irreparable damage to the retina of the human eye.
This is due to the high radiation level because the blue light content is so great. White light with a short wavelength of 400-500 nanometers suppresses the production of melatonin produced by the pineal gland. As a result, it disrupts the human circadian rhythm, leading to difficulty sleeping.
The emission capacity of led street light
Lighting levels higher than 10,000 cd/m2 cause visual discomfort regardless of the position of the lighting unit in view.
What is led street light? The emission surface of LED is a highly concentrated source; the brightness of each individual source can be 1000 times higher than the uncomfortable level. The level of direct radiation from this type of source can easily exceed the level of visual discomfort.
– Due to the outstanding advantages compared to traditional street lights, the price of led street lights will be higher, but often we still hear the saying “you get what you pay for”.
How to choose to buy led street lights?
To overcome this limitation, we should use LED street lights with yellow light for lighting, minimizing the negative impact that it causes. However, every product will have certain limitations, so we need to overcome and learn to choose the right type of street light.
LEDs with low power consumption
What is led street light? LED lights have the ability to save energy consumption from 70 to 80% compared to conventional lamps. On average, an LED with a capacity of about 5W will give the same light as a 20W regular light bulb. When using LED lighting, the initial cost may be more expensive, but in the long run, it is highly effective.
But now, there are many brands of cheap but good quality LED lights, more diverse for users to choose from.
3. LED lights have good light
The low power consumption does not mean that the LED light is of poor quality. Accordingly, a room equipped with LED lights will have a more peaceful and pleasing light compared to other types of bulbs. Therefore, this type of lamp is very popular for office lighting.
