Five points to be considered in the design of LED ice and snow landscape lighting system (two)

4, to ensure that the LED ice and snow landscape lighting system stable and reliable operation and good recovery of several technical points

The construction and operation environment of LED ice and snow landscape lighting system is bad, the maintenance is difficult, and the recycling requirement is good. There are two key points to ensure the reliability of LED ice and snow landscape lighting system.

(1) improve the protection level and impact resistance of each component

(2) LED lamps, cable connector, power supply and protection grade of the external controller should be guaranteed to reach more than IP67, while improving the impact resistance of these components, to ensure the system Recyclable reuse is crucial.

(3) to improve the adaptability of each component in low temperature environment and hot and cold alternating environment

The technical requirements of the main components are as follows:

1) LED light source device package: General silicone LED is reliable, hard epoxy LED, blue green often drop electrode fault, often caused by the red electrode cold alternate open circuit fault.

2 (LED) lamps: to give full consideration to whether the sealing process will be caused by hot and cold alternating lamp shell cracking, you can consider the use of silica gel sealing material, epoxy resin capping process.

3) integrated circuit driver selection: IC recommended using high-speed CMOS chip commercial grade, control of IC can be used in industrial grade products, the selection of passive devices is special, in the design must fully consider the low temperature of -20 DEG C and the deviation of the nominal value of the device.

4 cable selection: no matter the power supply cable or signal cable, must use low temperature rubber insulated wire, can not choose PVC plastic insulated wire.

5, LED ice and snow landscape lighting system standardization

The standardization of LED ice and snow landscape lighting system will reduce the cost of landscape lighting, reduce the management cost, reduce the project cost and improve the work efficiency. In the LED light distribution scheme, has been referred to the starting point of selecting RGB light distribution scheme is to prepare for the day after the standard. On the other hand, including driving part and control part, even the size of the lamp, are needed to form a standard, let more enterprises to provide products in accordance with the LED standard, and through competitive bidding, improve products, let the snow landscape lighting construction contractor to obtain maximum benefit through standardization, an important goal this is the LED and direction of the future development of snow and ice landscape lighting system.

In short, LED snow and ice landscape lighting is a new LED lighting applications, is a hitherto unknown innovation, it is a challenge to the development of application technology of LED lighting products, to enhance the effect of snow and ice landscape art will bring about a revolution!
