Explosion-proof luminaires are luminaires designed to prevent ignition of surrounding explosive mixtures such as explosive atmospheres, explosive dust environments, gas gases, etc. One of the most important explosion-proof principles of explosion-proof luminaires is to limit the temperature of the surface of the enclosure in contact with explosive gases, explosive dust, the surface of components or the surface of electronic components, and to limit the temperature of electrical contact surfaces below their minimum ignition or ignition temperatures.
Since LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low heat generation, low power consumption, safe voltage and low voltage, and long service life. Therefore, high-power white LEDs are explosion-proof lamps, especially portable explosion-proof lamps. A very ideal electric light source for lamps.
LED explosion-proof lamp, which belongs to a special electrical equipment used in special industries, mainly solves lighting problems. It includes a lamp housing, a lamp cover disposed at the front end of the lamp housing, an illuminator and a battery disposed inside the lamp housing, and a switch disposed on the surface of the lamp housing. , which is characterized by:
The illuminant is a high-power LED module, and a wide voltage input driving circuit is arranged between the illuminant and the battery; the wide voltage input driving circuit comprises a constant current chip, the constant current chip and the battery form a power module, and the LED module is connected at a constant On the flow chip, the power module is sealed with the LED module; ultrasonic welding is performed between the lamp cover and the lamp housing.
It utilizes the characteristics of low heat generation of LED to achieve intrinsically safe explosion-proof, and the LED light source has a long service life; the battery maintains constant brightness at the end of full charge and discharge; the heat dissipation device is arranged on the lamp housing to achieve effective heat dissipation of the LED module It guarantees the stability of use and is suitable for lighting in various industries such as coal mine, petroleum, railway and flood control.
Specific features of Grille Curtain LED Display
What is grille curtain LED Display Screen? grille curtain LED Display screen is made up of several pieces single led strip. It is a LED screen which looks like a grille and now become more and more popular among the LED industry. It can be called like strip Led screen. Since it shows us a hollowed-out , meshy visual effect, so LED display experts also call it mesh LED screen. This type of outdoor led screen mainly apply for wall of outdoor, glass wall, top of buildings, Column ads and led Curtain and so on.
Cross-time design of grille curtain LED breaks the limitation of traditional LED display for buildings and walls, makes the assembly project easier and selective. Maybe that is the reason why it can be used widely among all the field. Now let`s CATA editor introduce some technical advantage and how it makes the led screen project easier.
