At present, there are basically two kinds of sensors used for parking lot lighting. One is infrared sensor, which is relatively cheap. However, due to the height of the floor, the limitation of the metal tube and the influence of the radiation angle, the infrared sensor has a certain detection blind spot. The other is a microwave sensor, which can overcome the disadvantage of detecting corner blind areas, but the price is higher. These two sensors and major Smart street lamp Combined, the lighting energy saving of the underground parking lot is effectively realized. When someone moves the car under the light, major Smart street lamp It will run at full speed to meet the lighting demand. When there is no car and no car, the lamp is in a sleep state, and low power lighting of about 3W is maintained to maintain the required safety lighting. Low illumination, realizing energy saving of lighting.
Main pole of high pole lamp: major Smart street lamp When the height of the main pole exceeds 20m, the steel plate with a wall thickness of 5.6mm is usually used as the main material. After the overall welding of the high pole lamp, the internal and external surface layers need to be hot-dip galvanized and qualified galvanized. This process can ensure that the main pole will not rust for 15 years. Lifting system: the lifting system is regarded as the core part of the high pole lamp. The landing action of the light panel depends entirely on the landing system. The landing system of high pole lamp is mainly hoist and wire rope. First, install the elevator on the main rod. Weathering and rain will not cause line aging. Secondly, the hoist seldom starts. If major Smart street lamp If the light source has not been damaged in ten years, it will not need to be touched in ten years. Lamp cap: Whether it is LED lamp cap or low pressure sodium lamp, the light source is the main symbol of the whole set of high pole lamp. If the light source is broken and the high pole lamp is broken, the selection of light source quality is particularly important.
(1) Solar panel: 18v, 30-240wp monocrystalline silicon or polycrystalline silicon; (2) Controller: major Smart street lamp Intelligent controller; (3) Battery: DC12V, 24V, lead-acid battery or gel battery, maintenance free; (4) Light source type: high-power LED integrated lamp head, die-casting aluminum material; (5) Light source power: 20-60W; (6) Light pole material: steel structure, hot-dip galvanizing, plastic spraying treatment; (7) Height: 6-8m; (8) Working time: 5-12 hours, 4-5 days in rainy days (different sunshine time in different regions); (9) Working temperature: - 35 ℃ - 65 ℃; In addition, major Smart street lamp For the selection of solar panels and batteries, please refer to the purchase notes of solar street lamps. It can be seen that the selection of proper garden lamps is not only reasonable in price, but also comprehensive. In order to avoid unnecessary troubles.
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 Smart street 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 Smart street 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.
