Q:Constraints on LED street lights
Maintenance problem. High pressure sodium lamp is good for maintenance. As long as the lamp is scrubbed, it is not necessary to replace it. The light source is changed once every 4 years, which is very convenient. And LED street lamps, involving LED tubes, modules (including lenses, etc.), power devices, etc., components and components of the possibility of greater damage, maintenance difficulties, it is possible to replace the whole, higher costs. High price: LED street price is 2-5 times that of high pressure sodium lamp, even if the power consumption of LED lamp is only 1/2 HPS, but because the price is much higher than that of high pressure sodium lamp, high pressure sodium lamp is replaced by LED cost recovery cycle will still be very long;
Q:LED street lights around 2800K, the highest color temperature, how many lumens per watt?
Now LED 2800K color temperature, the maximum light effect is about 130LM/W
Q:How many watts does the LED street light have?
The technology is mature day by day, and the high-power LED light source can meet the needs of general street lamps. The general optical efficiency of high pressure sodium lamp is 100LM/W, high power LED is commonly used by foreign 50-60LM/W, the best LED chip can reach 80LM/W, the luminous efficiency is high, means that the energy saving effect is better, which is the choice of one of the most important indicators of LED street lamp. However, the LED standard does not specify this, so the purchase of LED street lamps must be carefully confirmed.
Q:Where can I buy LED street lamp and aluminum alloy shell, what's the quality of the product? Who can provide?
Advantage1, the lamp adopts Aluminum Alloy die-casting molding, can be effective in cooling and waterproof and dustproof. The surface of the lamp has been treated with UV resistance and corrosion resistance, and the overall lamp meets the IP65 standard;2, no bad glare, no strobe. The glare, visual fatigue and sight interference caused by the general glare of the street lamp are eliminated, and the driving safety is improved;3, the radiator and lamp shell integration design, the LED is closely connected with the shell, the shell wing and the air convection heat, and fully guarantee the LED lamp life.4, the single ellipse reflecting cavity is designed with the spherical isolated surface, the light emitted by the LED is controlled in the required range, and the uniformity of the luminous effect of the lamp and the utilization ratio of the light energy are improved.5, the number of chips per unit area can be flexibly designed and can be packaged into different point light sources or surface light sources as needed6, through different combinations can adapt to different voltage and current, adapt to the drive design, so as to improve the overall light efficiency
Q:What is the maximum power of a LED street lamp at present?
If it is integrated, this power can be achieved.
Q:Does the LED street lamp work well with a single light source or with integrated light sources?
Conditional words, of course, a single point is better, so that the light is not so obvious, and in tandem, bad 1, the whole string will not be bright
Q:The same brand of chips, how to judge the quality of LED lights?
Should pay attention to the cooling system for street lamp, street lamp cooling system is now divided into three types, one (die-casting aluminum (aluminum), two (three), Qi tablets) but also pay attention to the radiator is enough, there are many manufacturers have 90W heat lamps, used to install 120W to save the cost, so that his cooling system will follow no, my colleagues decay is relatively large
Q:Is there any national standard for surface coating of LED street lamp?
Yes, there is no specific standard in our country at present, as long as you can wear the standard of corrosion prevention!
Q:LED street lights are different from high pressure sodium lamps (both street lamps), as well as superior power consumption
At present, the most mature street light source, relative to the LED lamp, is not high enough for the use of the environment
Q:LED Street pressure is not enough, what will happen?
The shell will leak. If it rains, it's very serious
