1. Strong anti-static capability: LED with strong anti-static capability has a long service life. 2. Brightness: The price of LED varies with its brightness. 3. Wavelength: LEDs with the same wavelength and color are expensive. 4. Luminescence viewpoint: LEDs for different purposes have different luminescence viewpoints. 5. LED chip: major Landscape lamp The illuminant of is a chip, and the price of different chips varies greatly. 7. Colloid: Generally, the colloid of LED is epoxy resin. LEDs with UV resistance and flame retardancy are more expensive. 8. Chip size: the chip size is represented by the side length. Big chip major Landscape lamp Its quality is better than that of small chips. The price is proportional to the chip size. 9. Radiator: The radiator can see the appearance of the lamp. Temperature will affect the life of LED lamp beads. Counting plays a vital role. 10. Power supply: According to the plan requirements of different manufacturers, it can be divided into two types: constant current power supply and constant voltage power supply.

The life of LED mining lamp depends largely on the level of heat dissipation, and the main way to improve the level of heat dissipation is to transfer the excess heat generated by the chip through the radiator and radiator. At the same time, major Landscape lamp The main parameters related to LED heat dissipation are thermal resistance, junction temperature, temperature rise, etc. Thermal resistance is the quotient obtained by dividing the difference between the effective temperature of the equipment and the temperature of the external designated reference point by the steady-state power consumption in the equipment. It is an important parameter indicating the degree of heat dissipation of equipment. Junction temperature refers to the temperature of the semiconductor junction of the main heating part in the LED device. It reflects major Landscape lamp Temperature value that can be withstood under working conditions. Temperature rise refers to the temperature rise of the enclosure environment. It refers to the difference between the temperature of LED equipment shell and the ambient temperature. This is a temperature value that can be directly measured, which can directly reflect the heat dissipation degree around LED devices.

If there is a problem with the solar street lamp in the countryside, first check whether the photocell is correctly connected, whether the wiring position is in poor contact, and then check whether the battery connection is correct and whether the battery voltage is normal. If the battery is excessively discharged, a fault will occur and it will automatically recover after being fully charged. Among them, major Landscape lamp The stability of the controller is very important for the service life of rural solar street lights, because the role of the solar controller is to control the use major Landscape lamp The battery board charges and discharges the battery. When choosing a solar cell, you must choose a high stability battery to ensure the service life of the battery, because the quality of the battery will also directly affect the service life of the street lamp. It can extend the service life of the whole rural solar street lamp.

First, we need to observe major Landscape lamp The workmanship of the mask and its luminous effect. This depends on how much light the bulb lamp shade emits to the light source. When viewing the mask, you can view its shape, whether the light transmittance and thickness of the bulb are the same, and check the approximate blur of the mask. We need to see if the material of the bulb is suitable for heat conduction. You can test in the field. After working for several minutes, observe whether there is odor above the bulb when the temperature rises. After that, we will also check the lamp body temperature after the power is turned off. The lower the temperature, the better. ordinary major Landscape lamp It will change due to the change of ambient temperature. When selecting bulb lamp, you need to check its color temperature. Generally speaking, the color temperature should not be too high or too low as long as it can meet the normal household lighting needs.
