Advantages of 48V lamps over 24V lamps:
1.The current of 48V lamps with the same power is reduced by half. According to the line heat loss q = I2R, R is constant, and the resulting loss is directly proportional to the square of the current, that is, the current plays a decisive role in the circuit loss.
2. Series and parallel connection of lamps; Compared with 24V lamps, 48V lamps are doubled in series, with less low-voltage lines and conduits, less labor, and convenient and fast installation.
3. The impact of line voltage drop on lamps and lanterns. If 2V voltage drop is generated in the line, 2V / 24V of 24V lamps and lanterns is equivalent to one twentieth of the voltage drop; 48V lamp 2V / 48V is equivalent to one twenty fourth of the voltage drop. It can be seen that the higher the voltage, the smaller the proportion of voltage drop.
Design concept of patented wall washing lamp (el-xqd3827)
1. The lamp body is made of 6063 aluminum material with strong comprehensive performance. The surface is anodized and has good corrosion resistance and heat dissipation
2. The front narrow frame design, the glass screen printing is the same size as the lens, the workmanship should be fine and accurate, and the overall structure should be perfect and generous
3. The lamp beads are close to both ends, and the distance between the illuminants at the connection position of the two lamps is the same as that in the middle. The luminescence forms a seamless butt joint, and the light has no shadow
4. There are three radiating fins on the side to increase the radiating area and flexibly fix the mounting bracket
5. The lens is close to the glass to minimize the refraction and loss of light and ensure the light effect
6. Multiple loose holding pieces are designed to heighten the lamp body, increase the heat dissipation area, ensure the heat dissipation of LED, increase the size and improve the aesthetics
7. Zinc alloy die casting plug is durable and beautiful
8. The length of the fixing bracket screw is just right, which reflects the more exquisite appearance of the overall lamp.
Lamp size: 1000 * 38 * 27, length of meter
