LED
production process demanding, in order to meet the design requirements,
the process of demanding manufacturers will be a large number of LED
tube consistency screening, taking into account the thickness of the LED
tube on the circuit board in the gap between the manufacturers will use
automated Laser welding process.
Not all companies have the appropriate strength, resulting in the quality of the market LED display varies greatly. LED lighting system design requirements are very sophisticated,
LED tube and condenser cup size are small, both the relative position
with the higher requirements, small deviations, the light reaches the
stage position there will be a big gap.
First, the cooling problem directly affects the LED luminous efficiency. The current high-quality LED display design and process to
solve the cooling problem, you can have more than 30,000 hours of life,
but poor design or process LED display may be only a few thousand hours
or even shorter life expectancy.
Second,
professional development, design, strict management of production,
enterprises from the selection of components and materials, from the
advanced automation of machinery to the production process of strict
quality control (including the aging of intermediate parts), each link
affects LED display quality. Despite some problems, but the prospects of LED advertising screen or LED display, the performance is consistent with people.
LED light efficiency continues to increase, the price continues to decline.
Single-die
LED power and luminous efficiency continues to improve, a comprehensive
analysis of LED display, performance comparison, the high price of LED
advertising screen lighting is mainly reflected in the one-time
investment, from the perspective of long-term use and effectiveness, High price is still understandable. The support of national policy and the update of user's concept will enlarge the application of LED display. More
importantly, with the expansion of applications and the development of
LED display industry, a large number of production will further
contribute to the formation of a virtuous cycle of a declining cost and
price, a declining cost and an expansion of applications. This will have
a positive effect. Of course, this requires manufacturers and users vLED display, performance cooperation and efforts.
Third, reduce the use of peripheral devices (dimmers, color changers), saving costs;
Fourth, reduce maintenance workload, reducing the cost of use.
Labs
have been able to achieve more than 160lm / W (also known as over 190lm
/ W) LED display, performance, commercial products also have hundreds
of lumen per watt efficiency, the scientists goal is 200lm / W.
Single-die products There will be double the power increase.
Although
the LED advertising screen higher prices, but even now there is still
the use of value: First, the savings in line with the national policy of
energy conservation; Second, the light source several times longer than
the incandescent lamp of the price-sharing.
