Series H Lighting Street In the main Street In Thailand

This is a project in Thailand installed with ZGSM H series street lights. More than 300 pieces of street lights are used to replace old lamps. With enough lighting in this area, the traffic order has been well improved. And the client told us, the accidents in this crowded area seldomly happen anymore. More important is that we saved more than 65% on electricity bills after this road infrastructure renovation.

The concept of a smart city is gaining popularity. It could refer to projects aimed at making cities more livable and really sustainable. It’s a problem-solving technique in which new technologies collaborate to improve infrastructure while minimizing environmental impact. LED street lights provide an opportunity to establish a connected, efficient, and safe urban lighting network, which is the essential foundation for implementing smart city systems.
Because of their energy efficiency and long lifetime, LED street lighting systems can provide immediate benefits to smart cities. They are advertised as a green lighting alternative since they are environmentally friendly and cut carbon emissions. As a result, smart cities are increasingly incorporating it to promote a greener environment.

  1. Varied LED brightness (MCD) means different prices. The laser class I standard should be met by the LEDs used in LED lamps.
  2. LEDs with good antistatic properties have a long service life and are expensive. LED street lamps can often employ LEDs with antistatic voltage greater than 700V.
  3. The color of LEDs with the same wavelength is the same. When the color must be the same, however, the cost is substantial. Manufacturers without LED spectrophotometers find it challenging to create items with pure colors.
  4. An LED is a conductive light-emitting device that emits light in only one direction. Leakage occurs when there is a reverse current. LEDs with a high leakage current have a limited life span and are inexpensive.
  5. Different LEDs emit light at different angles depending on their intended application. The cost of a special lighting angle is greater. The cost of a full diffusion angle, for example, is greater.
  6. Service life, which is defined by light decay, is the key to quality. Low light degradation, long life, and expensive price are all advantages
  7. The chip is the luminous component of an LED street light, and the cost of different chips varies substantially. Chips are more expensive in Japan and the United States. Chip prices in Taiwan and China are often lower than in Japan and the United States (CREE).
  8. The chip’s size is determined by its side length. The huge LED chip has a higher quality than the little LED chip. However, the price is clearly related to the chip’s size.
  9. The ability to dissipate heat is critical. Because an LED is a semiconductor device, when its chip’s luminous flux is decreased to 30% of its initial value owing to temperature, it loses its lighting meaning, and therefore its life. High-power LED street lights have a theoretical lifespan of 3.5 million hours, but good heat dissipation is a must.
  10. The LED light’s outside material should be a pure Polyester-based powder coating that can handle sunshine and outdoor weather, as well as a solid heavy-duty aluminum body that can withstand wind/rain and other severe weather.
  11. The products must be waterproof to IP65 standards.
  12. Calculate the wattage and column height of the street light based on the road width, the distance between poles, safety considerations, installation regions (rural, town, or metropolis), traffic volume, and public or private use.

Power of LED Lamp

The more internal LED beads, the higher the LED lamp’s power.
When a single lamp bead has the same brightness, LED lamps with more internal lamp beads must have greater brightness.
LED street lamps, on the other hand, have a modest brightness.

The luminous efficacy of LEDs inside the LED lamp fixture

The luminous effectiveness of LED lamp beads is a critical aspect in determining the overall brightness of the LED lamp fixture.
When LED lights have the same power, the higher the luminous effectiveness of LED lamp beads, the brighter the LED street lamps.

Heat dissipation of LED street light fixture

LED street lamps’ heat dissipation is another major component that affects their brilliance.
Internal current and total brightness will be more stable in LED street lighting with effective heat dissipation.
The internal temperature of LED bulbs will be excessively high if the heat dissipation performance is weak.
When the internal temperature is too high, the light decay of LED chips is accelerated, resulting in LED lamp dimming.

Internal LEDs in series and parallel

The input current required is relatively minimal if the parallel number of LED lamp beads is more than the series number, and the brightness of LED street lighting is increased. LED street lamps, on the other hand, will be less brilliant.

The quality of LED chips and Driver

Brand manufacturers make higher-quality LED lamp beads and power supplies, using superior materials and processes than tiny workshops.
Of course, LED street light fixtures provide a better overall brightness effect.
