1.cause Many users have been criticized for price problems when they purchase programmable led flood light. They are either too high or too low, and the prices are very different, making it impossible to identify. The configuration of the programmable led flood light seems simple, but it is not simple, and there are many details that are the source of the difference. Professional lighting has been developed for more than 30 years. With the advancement of the government's energy conservation and emission reduction projects, it is imperative that LED lighting replace traditional lighting. However, there are many manufacturers of LED and LED lamps. Different manufacturers use LED lighting lamps made of different materials to form uneven quality, so there are different prices, and the market has set off various storms. Due to the increasingly fierce price war, the products with almost the same appearance, structure and function have a price difference of 2-3 times. Many users are blinde...

1, the brightness of the brightness is different, the price is different. For luminaires, it should meet the laser class I standard. 2, anti-static ability anti-static ability, long life, and therefore high price. Generally, antistatic is greater than 700V for lighting. 3. The wavelengths are the same, the colors are the same. If the colors are the same, the price is high. It is difficult for manufacturers without spectrophotometers to produce pure color color led flood light products. 4.The leakage current is a unidirectional conductive illuminator. If there is a reverse current, it is called leakage, the leakage current is large, the life is short, and the price is low. 5. The illumination angle is different for different illumination angles. Special lighting angle, the price is higher. Such as full diffusing angle, the price is higher. 6. The key to different quality of life is life, and life is determined by light decay. Low light decay, long life, long life and color led flood...

1.What is a high-power led flood light? A: A lighting fixture that uses high-power LEDs as a light source. 2.What is a high power LED? A: The high-power LED is broadly said to be a single LED light source with a power greater than 0.35W (including 0.35W). 3.What are the advantages of high-power led flood light compared to traditional flood light? Answer: 1. High luminous efficiency 2. High energy saving 3. High light color 4. High safety 5. Diversity of design shape 6. Long life 7. Fast response 8. Reasonable structure of lighting 9. Environmental protection, better environmental protection 10 High-tech. 11. Low operating cost 12. The color temperature does not change much, less than 100K, the color temperature consistency is good 13. The lumen maintenance rate is high, the light decay is slow, and the light decay is less than 10% after 5000 hours. 4.How to dissipate high-power led flood light? Answer: The heat generated by the LED light source is transmitted to the heat sink by the...

The outdoor basketball court, as one of the most popular sports venues, can be seen everywhere in the city's sports centers, cultural squares, residential areas, primary and secondary schools. In addition to being used as a first choice for physical exercise by boys, the modern basketball court has become the best place for children to entertain and play! The following is an example of an outdoor basketball court as an example to introduce the lighting patterns and lighting methods of the general outdoor basketball court lighting scheme: Outdoor open-air stadium lighting, the way the venue is installed differently is not the same. The standard is to determine the standard of lighting according to the function of the course, which is roughly divided into the following levels: Training and entertainment activities illuminance 120-300lx; Amateur competition 300-500lx; Professional competition 500-800lx; General tv broadcast ≥1000lx; Large-scale international competition HDTV broadcast ...
