Outdoor street lamp has energy economy and environmental protection, as well as high luminous efficiency, a long service life, and a pleasant city street lighting effect. At the moment, LED street lights have mostly displaced classic high-pressure sodium lamps. Are you aware of the accessories available for outdoor LED roadway lights?

Typically, a full set of LED lighting fixtures comprises the following components: LED light source (LED lamp beads), driving power supply, controller, heat sink, and housing, among others.

LED light source

Currently, the lighting market’s most prevalent light sources include direct current energy-saving lamps, high-frequency chemical lamps, low-pressure sodium lamps, and LED light sources. A LED light source (LED stands for Light Emitting Diode) is a lamp made of light-emitting diodes. This light source is compact, has a long life, is highly efficient, and has a service life of up to 100,000 hours. LED light sources have been widely used in lighting applications.
LED light sources are a new generation of light sources. In comparison to incandescent, high-pressure sodium lamps, and other classic thermal radiation and gas-discharge light sources, LED light sources have the following benefits in road lighting.

1. High lumen output

After decades of technological advancements, the LED’s luminous efficiency has been significantly increased. Incandescent and tungsten-halogen lights have a luminous efficiency of 12-24 lumens per watt, fluorescent lamps have a luminous efficiency of 50-70 lumens per watt, and sodium lamps have a luminous efficiency of 90-140 lumens per watt. The majority of electrical energy used is lost as heat. After improvement, LED luminous efficiency may reach 50-200 lumens per watt, the light is monochromatic and has a narrow spectrum, which means that it can be sent directly without color visible light filtering.

2. Less power consumption

LED single tube power 0.03-0.06 watts, direct current drive, single tube driving voltage 1.S5-3.5 volts, current 15-18 mA, quick reaction time, high-frequency operation. Under identical lighting circumstances, the power consumption of an LED lamp is one-tenth that of an incandescent bulb and half that of a fluorescent lamp.

3. Long lifetime

LED lights and lanterns have a service life of up to 10-20 years, which significantly reduces lamp and lantern maintenance costs and eliminates the inconvenience of frequent lamp and lantern replacement.

4. Strong safety and reliability

LED lights and lanterns generate little heat, emit no heat, provide a cool light source, and are touch-safe.

5. Environmental protection

LED is a completely solid-state luminous body that is shock-resistant, impact-resistant, difficult to break, recyclable, and emits no pollution.

LED driver

To put it another way, LED drive power is a converter. Its purpose is to convert the voltage and current from our standard mains or other power supply to those suitable for LED use. The LED can function correctly and light up due to its conversion. To unscrew a nut, for example, we must use the same sort of tool.
Not only is the LED driver power supply an integral aspect of LED lighting fixtures, but it is also a significant factor determining the stability of LED lights. Therefore, how do you choose the proper driver power supply for led lights? This is a worthwhile consideration!

Heat sink

The purpose of the outdoor led street light heat sink is to absorb heat from the substrate or chip and then disperse it to the surrounding environment in order to maintain the LED chip’s normal operating temperature. The majority of heat sinks are meticulously engineered for usage in both natural and forced convection modes.
When discussing heat sinks, it is vital to discuss their shortcomings and potential solutions for dissipating the heat generated by LED street lights. Many people in everyday life are aware that LED lights can brighten our roadways, but are unaware that the street lamp head also has a heat sink mechanism. Just like humans need a sweating system during the hot summer months, they require a fan to cool off. LED street lights operate outside for an extended period of time, and since the outdoor temperature difference is rather considerable, a good heat dissipation system is required. If heat dissipation is not properly addressed, especially for high-power LED street lights, light degradation will be significant and life duration cannot be assured.

LED lamp housing

Not only can an LED housing protect the LED from external components, but it may also act as a heat sink and regulate the LED’s temperature.

The information above is my understanding of the primary lighting accessories for LED street lights. In a nutshell, each lighting accessory for outdoor led street light has a purpose, and one cannot be overlooked. As a result, we must routinely inspect and repair led light accessories to guarantee their proper operation and service life.

There are several types of LED lights available on the market; if you’re looking to purchase led street lights, which ones are the best? Consider the street light wattage, power usage, and if the light is sufficiently bright. These common-sense notions influence the selection of LED lighting fixtures and the evaluation of their positive and negative attributes.
It’s common for people to believe that the greater the wattage, the brighter the light. Of course, the same wattage LED street lights are also more affordable, which is another perplexing idea. The terms wattage and brightness are not synonymous; brightness is sometimes referred to as luminous efficiency; pay close attention to the luminous efficiency.
The luminous efficiency of an electric light source is defined as the luminous flux emitted by the source, and its power ratio, expressed in lumens per watt (LM / W), is the most critical technical metric for evaluating the luminous efficiency of electric light sources. The term “luminous flux” refers to the quantity of light emitted per unit of time, measured in lumens. The bigger the luminous flux of a light source per unit of power, the better the electrical energy conversion efficiency, or luminous efficiency.

Average luminance and illuminance

From the driver’s perspective, the driver’s assessment of road conditions is largely determined by the road’s average brightness and lighting. At night, when the human eye is in an intermediate visual stage, the color contrast between objects is minimal. It is mostly based on the brightness of items and their surroundings to differentiate them, and so the brightness and lighting of the road will impact the driver’s contrast, as well as the brightness of objects and the contrast of the road.

Uniformity of road brightness and illumination

If the road’s brightness and light are not uniform, excessive glare will result, while excessive darkness will create a visual black region, preventing the driver from identifying surrounding obstructions, and posing a safety risk.

Glare reduction

In other words, glare occurs as a consequence of excessive brightness or contrast within the optical range. Glare is classified into two types: damaging glare and annoying glare. The former impairs the human body’s natural visual function, yet the human eye does not necessarily feel unpleasant. The latter is the opposite: it does not always impair the human eye’s visual function, but may make it feel unpleasant.

Visual guidance

To ensure the safety and convenience of road users, road lighting is installed in a dense pattern along the road alignment to enhance visual guidance. Visual guidance is particularly critical at some bends and junctions.

The preceding statements are based on an analysis of our led street lights from a driver’s night driving perspective. Additionally, there are other performance factors and requirements to consider. Different application situations demand varying levels of quality from LED street lights.
