Yuannengji Ang mga LED underground lights ay may iba't ibang kulay, at maaaring makamit ang pula, dilaw, asul, berde, puti, makulay na pagtalon, gradient at iba pang mga epekto.
Ang mga LED underground na ilaw ay may mga katangian ng mataas na liwanag, mababang pagkonsumo ng enerhiya, malambot na liwanag, walang glare, atbp., at ang kanilang kahusayan ay maaaring maabot 85%.
Ang input voltage ng high-power LED underground lights ay AC 220V o DC 24V. Ang pinagmumulan ng ilaw ay maaaring gumamit ng karaniwang low-power light source at high-power 1W light source, COB light source. Ang ganitong uri ng lamp ay malawakang ginagamit sa pag-iilaw ng mga berdeng sinturon, mga parke, mga damuhan, mga patyo, mga lansangan ng pedestrian, mga parisukat at iba pang lugar.
Ang baso ng LED underground lamp ay dapat na tempered at walang stress. Ang lakas nito ay dapat na makatiis sa puwersa ng epekto na 2~4N/cm at kapal na 5-10mm. Ang tigas ng singsing ng goma ay dapat umabot sa 35H, at dapat gumamit ng isang hugis-U na singsing na goma, dahil ang gayong singsing na goma ay maaaring direktang ilagay sa salamin.
Before installing the LED underground lamp, you must organize the various parts of the lamp. LED underground lamps are special landscape LED lamps buried underground. If a part is missing during installation, it is very troublesome to reinstall. Before installing LED underground lamps, you should first dig a pit according to the size of the embedded parts, and then fix the embedded parts with concrete.
The embedded parts isolate the main body of the LED underground lamp from the soil, which can ensure the service life of the LED underground lamp. Before installing the LED underground lamp, you should prepare IP67 or IP68 wiring devices to connect the external power input to the power cord of the lamp body. Bilang karagdagan, the power cord of the LED underground lamp must use a VDE-certified waterproof power cord to ensure the service life of the LED underground lamp. The waterproof lens and tempered glass must be kept at a certain distance to avoid affecting the light quality.
The input current of the high-power LED underground lamp is AC 220V or DC 24V. The light source can use standard low-power (5 or SMD2835, SMD5730, SMD5630) light source and high-power 1W light source, COB light source. This type of lamp is widely used in road greening, ecological parks, mga patyo, commercial streets, underground parking lots, city squares and other places.
The waterproof lens must be kept at a certain distance from the tempered laminated glass to avoid affecting the light quality. Regarding the design of the wiring hole, many people use the traditional PG7 to solve the waterproof problem of LED underground lamps. This is also a misunderstanding. The traditional PG is waterproofed by adding a round rubber ring and pressing the outer shell. Because the contact surface between the rubber ring and the lamp body is limited, if it is used outdoors for rain protection, there is no problem. If it is used on LED underground lamps, it is indeed worth discussing. The V-shaped rubber ring is pressed into the V-shaped hole through a nut to prevent water from penetrating from the edge of the rubber ring and around the wire skin. The rubber ring uses a large and thick flat round gasket, and the wire inlet is sealed with epoxy resin.
The rubber pad between the upper cover and the lamp body, the above method is for waterproofing the lower part of the lamp body, and here we are talking about waterproofing the upper part of the lamp body. Some people use stainless steel shells as lamp bodies and find that water still enters the lamp because the water or moisture here is not handled well and is sucked in.
