Huaqiang Security Network News ] It is understood that LED street lights are basically white light at the color temperature of about 5000K. As a road illumination source, the visual sense is too cold and cold, and the observing ability will decrease when it is farsighted. In this respect, the street lamp use unit has the most say, and the yellow or warm white light of about 3000K is more suitable for road lighting, so the daylight color LED street light Not suitable for street lighting.
Today's LED street lamps lack uniform technical standards in terms of product specifications. At present, there is no unified technical standard for LED street lamp production. Each manufacturer produces its own products according to its own standards. It is difficult to be common to each other. In addition, LED street lamp manufacturers The lamps are self-contained, the light source electrical assembly and the lamps are bundled together, and their different working characteristics are difficult to maintain. The original products must be used for maintenance. Due to the unification of technical standards, high-pressure sodium lamps have strong versatility in lamps, light sources and electrical appliances. Products from different manufacturers can be used interchangeably. This is very important from the perspective of maintenance, and maintenance is also important for street lighting management units. It is the most important thing. Only in this way can the faulty street lamp be maintained in time to ensure the perfect lighting rate (the most important part of the street lighting management assessment by the superior department), and greatly reduce the maintenance cost. It can be said that under the current development of LED street lights, in the event of a fault, only the entire luminaire can be replaced. In addition to the high cost, the maintenance time should be greatly increased, which is very unfavorable for the user. For the maintenance of lamps, conventional lighting fixtures are much simpler, and the light source appliances can be directly replaced at the site, and the cost is also low. However, many manufacturers' LED street lights may be considered maintenance-free by the manufacturers, so the on-site maintenance cannot be carried out, and the real burden of maintenance is still given to the manufacturer. As everyone knows; the bottleneck that makes the product difficult to promote is still from the direct use of the unit.
Two major challenges for today's LED streetlight applications:
1. Difficulties in maintenance 2. Bottlenecks of high-power LED power supply According to these two difficulties, I personally recommend it; from safety and maintenance, it is easy to replace and avoid the quality risk of high-power power supply. Modular modular design must be the direction of development. Made into standard modular, such as 30w, 40w, 50w together with the power supply integration. Not only solves the risk of high-power power supply, but also facilitates the replacement of faults. The single-group module can also be used for a variety of lamps, which can be converted into LED tunnel lights, LED ceiling lights, LED wall washers, LED flood lights, LED tunnel lights, etc.
The heat-dissipating material, the heat-conducting link and the scientific shape structure design are worthy of everyone's understanding in the production of high-power LED street lamps. From the doubts and even rejection of the LED street lamp market, to the current trial and acceptance, we have seen the dawn of the future, but we still need some way to go. With the continuous improvement of high-power LED light efficiency and the rapid development of silicon-based LEDs, it will fundamentally solve the bottleneck of high price of semiconductor lighting sources. Let us join hands to explore and discuss. I believe that with everyone’s efforts, use the fourth. Generation of light source to make better LED street lighting, replacing the high-pressure sodium street lamp this road will not be very far!
