Night cityscapes require lighting and appropriate lighting design to give the city a different life and atmosphere. Designers use different lighting design techniques to express the structure and appearance of the building, so that it can exude the beauty of modern building structural mechanics, and the ancient buildings can be expressed in antique and full of charm. Ancient architecture is a historical relic and a resource of culture. It has undergone countless times and the baptism of nature. They are non-renewable and modern lighting design and implementation must be achieved with reliable protection. This lighting for ancient buildings is different from the general night lighting requirements.
At present, high-power high-pressure gas discharge lamps are widely used in urban night lighting. Even small buildings in general use a lot of energy, causing excessive waste of energy; and often throwing too much light into the night sky, not only wasting power, but also forming light pollution, destroying the natural environment, and reproducing the beauty of architectural art. . This also involves ancient architecture. The ancient buildings are exposed to the sun and ultraviolet rays during the day, and they are exposed to ultraviolet rays from high-pressure gas discharge lamps at night, which accelerates the damage of the appearance of ancient buildings. In recent years, LED lighting equipment has developed rapidly, and various professional lamps can better meet the needs of special decorative lighting such as ancient buildings. It not only has the characteristics of small size, low power, and saturated color, but also does not have ultraviolet light. The shape of the daytime lamp will not affect the overall landscape of the building, and it will not cause ultraviolet damage to buildings and night sky at night, but also the building. The appearance of the object is beautifully decorated.
The theoretical life of LED light source can reach 100,000 hours, the practical application life is tens of thousands of hours, and the power saving effect is obvious. This is the advantage that everyone has been emphasizing. However, at present, many advantages cannot be seen in the night lighting project. The user sees that the light decay is severe and the life is short, and it is broken in less than 10,000 hours. This is because the LEDs that people generally use are the Ф3mm~Ф5mm display type LEDs that are most commonly used in the electronics industry. They can increase the luminous intensity by increasing the current with a simple electronic circuit. However, the use of LEDs in this way only achieves a short high brightness, but loses the life expectancy of the LED.
Pinneng Optoelectronics understands the needs of lighting applications, using the internationally advanced LUMILEDS high-power ultra-high brightness LED (Superflux series and Lux-eon series), no matter the light output, light decay value, life and driver circuit are traditional LED can not be compared of.
With a good LED or not. The circuit design of the driver and the light board is also very important. For these, Pinon Optoelectronics has developed a series of "fixed voltage and constant current control" electronic circuits, using high-tech integrated circuit technology to control the input current of each LED to the optimal current value, so that the LED can obtain a stable current, and Produces the highest output luminous flux, while the LED lifetime can reach 100,000 hours and still have 70% of the light output.
Heat dissipation is also very important for LEDs. It affects the light output and lifetime of the LED. Pinergy Optoelectronics has also developed a series of MCPCBLED products with heat sinks for this problem; at the same time, it is suitable for the application of thermal adhesive materials. The LED products after the glue filling have good heat dissipation and better waterproof performance, and will not be short-circuited even if placed in water. If any appliance enters the water, it will cause a short circuit on the circuit, causing damage to the appliance, as well as LEDs. If the positive and negative electrodes of the LED enter the water, or the line that drives the LED enters the water, it will quickly affect the life of the LED. Pinergy Optoelectronics has a good solution in the problem of LED waterproofing. A number of waterproof patented products can specifically target the characteristics of ancient buildings. LumiLEDs1W high-power ultra-high brightness LED has been used to develop an ancient architectural LED flood light. Its installation is simple and versatile, and the style is novel and exquisite, which not only can meet the demand of illumination brightness, but also because it is small, the light source can not be seen during the day. Therefore, it will not destroy the beauty of the ancient buildings during the day. This product has been used in Xi'an, Tengchong County and Yunnan Shunqiao Township in Yunnan Province, and has won great praise from lighting designers and owners.
After the establishment of a branch in Shanghai, Pinneng Optoelectronics Co., Ltd. launched a series of LED lighting products to promote the progress of semiconductor lighting in China. At the same time, it also brought a series of overall solutions for ancient architectural lighting. It is hoped that in the near future, more and more Chinese ancient buildings will show their more charming charms under the backdrop of ultra-high brightness LEDs.
