Information

　　LED roadway lights are mainly suitable for fixed and continuous lighting in various places with explosion-proof requirements such as roadways, hoisting rails, conveyor lanes, ports, roads and other places with explosive gas environments such as methane and coal dust in coal mines. Below, the editor will briefly introduce the use of LED explosion-proof lights and their precautions.

The use of LED roadway lights:

1. According to the site environment and lighting needs, determine the installation location and appropriate installation method of lamps and ballasts, and prepare three-core cables of corresponding lengths according to the distance from the ballast to the 127V power supply contact.

2. In the determined installation position, fix the lamps and ballasts.

3. Tighten the bolt with a socket wrench, and one end of the three-core cable is introduced into the ballast cavity through the introduction device of the ballast output port. Connect the wires to the terminals of the ballast respectively, then use the lead clip to compress the three-core cable and then tighten the compression nut.

4. Close the ballast box cover and tighten the fastening bolts, and then connect the other end of the three-core cable to the 127V power supply to achieve lighting.

5. When replacing the bulb, cut off the power first.

Precautions for LED explosion-proof lights:

1. When installing and maintaining lamps, the power supply must be cut off, and live operation is strictly prohibited.

2. When using, the surface of the lamp has a certain temperature rise, which is a normal phenomenon. The center temperature of the transparent parts is high and should not be touched.

3. If the external flexible cable or cord of this luminaire is damaged, the line should be replaced by the manufacturer or its service agent or a qualified person.

　 The above is the introduction of the use of LED explosion-proof lights and the precautions, I hope to help everyone.

What are the characteristics of LED roadway lights? Do you know the installation method and precautions? Take a look!

　　As people's requirements for lamps are getting higher and higher, a new type of lamps called LED lamps are favored by people. LED is a kind of light-emitting diode. As a light source for illuminants, it has high light efficiency and long life. To achieve multi-purpose lighting, and softened, it will not cause dazzling or other uncomfortable reactions, so many public areas will use this kind of light, such as LED roadway lights, because there are many people on the road, so it is necessary to To install soft lamps that will not hurt the eyes, what are the characteristics of LED road lights? Do you know its installation methods and precautions? Let's follow the editor to learn about it. 　　 Features of LED roadway lights: 1. The color purity of LED roadway lamps is high; at present, LED products cover almost the entire visible spectrum range, and the color purity is high. 2. LED roadway lamps have a long life. The actual life of LED is more than 50,000 hours, which is several times or even dozens of times that of general light sources. 3. The light source of LED roadway lamps does not contain mercury, and the light beam does not contain ultraviolet rays. 4. It is solid luminescence, good shock resistance, firm and reliable. 5. It also has the characteristics of energy saving, economical and maintenance-free. 6. LED has strong luminous directionality, high luminous flux utilization rate, and small size, which is easy to design and control light intensity distribution of LED lamps. 7. LED roadway lamps can be powered by DC low voltage, which is safe and reliable. 8. The LED is not limited by the start-up temperature, it can be started temporarily, usually a few ms, and can temporarily achieve full luminous flux output. 　 Installation method and precautions of LED roadway lights: 1. Installation method: 1. First, determine the installation position and method of the lamps according to the actual needs of the work site, and then prepare the corresponding length of Φ8~Φ14 mm three-core cables according to the distance from the lamps to the power contacts. 2. Open the set screw on the side of the upper cover of the lamp, then loosen the compression nut of the cable inlet of the lamp, open the upper cover, and lead the power cables through the compression nut to the internal terminal, and connect according to the method shown in the figure. Fix it, and then tighten the cable compression nut and the upper cover of the lamp. 3. The LED roadway lights are enclosure-free. If the lamps themselves are not bright, generally communicate with the manufacturer for direct replacement or return to the factory for maintenance. 2. Notes: 1. The power supply must be cut off before dismantling the lamp. 2. It is strictly forbidden to open it with electricity. 3. During use, the surface of the lamp has a certain temperature rise, which is a normal phenomenon; the center of the transparent part has a high temperature and should not be touched. 4. When installing lamps, the lamps should be safely grounded nearby. The above are the characteristics of LED roadway lights, as well as its installation methods and precautions. Relevant staff must pay attention to the problems during installation to ensure their personal safety.
