Sensor LED tube for garage have been widely used, and some minor problems have been found during actual use. Now the manufacturers have solved them. The actual use effect is still relatively ideal, achieving the expected goals, such as energy saving, environmental protection, and intelligent control. The advantages of traditional fluorescent lamps are very obvious. However, the requirements of customers are not stopped, and they want to further improve.
No, on May 30, 2021, a customer called and asked for a customized LED tube for the garage, and put forward higher requirements. The requirements are as follows
1. "High energy efficiency 8+3W LED lamp (the lamp tube is 8W when someone or a car passes by, and no one is 3W after 30 seconds to maintain basic lighting), warranty for more than 5 years, brightness: more than 100 from the lamp tube more than 2 meters, Power factor 85%"
Second, explain what customers mean:
sensor LED tube for garage
1. Total power 8w
2. Standby 3w
3. Delay 30 seconds
4. Illumination requirement 100lux/2 meters
5. Power factor 85%
6. Warranty for more than 5 years
Take a look at the parameters and understand. The requirements are still quite high. What is the difficulty of this kind of garage LED lamp?
Due to the low total power, only 8w, but the illuminance value is too high. The only way to improve the brightness is the luminous efficiency. There are many ways to improve the luminous efficiency, such as the brightness of a single lamp bead and increasing the number of LED lamp beads. Improve the power conversion rate and increase the light transmittance of the PC cover; generally, the factory uses an integrating sphere test, which is simple and convenient, and the customer requires to test the illuminance. We only use an illuminance meter to test. There is another indicator, that is, the power factor, that is, we It is usually called the PF value, which is also an energy-saving indicator, and the maximum value of this indicator is 1.
The problem is coming. The PF value has a characteristic. According to the law of modern power supply technology, the smaller the power, the PF value is not easy to increase. Generally more than ten watts, it is easy to do, and this presents a problem.
How to solve this problem? Now that the customer has put forward it, in order to meet its requirements, our engineers in the technical department of Langte Company have worked hard to solve the problem, tested and verified many times, and finally reached the customer's index and met the customer's request.
It seems that the needs of the market are the driving force to promote the improvement of the company's R&D capabilities, and progress is endless. It cannot meet the status quo. It is necessary to cooperate with customers and improve innovation capabilities. The production of distinctive LED lights for garages is the last word.
Knowledge point: what is high light efficiency
The luminous efficiency is the luminous flux per watt of the lamp, expressed by the formula: luminous efficiency = luminous flux/power. Therefore, the higher the luminous efficiency of the LED, the larger the luminous flux value per W.
In the case of the same total power, the brighter the luminous flux of the lamp, the brighter the lamp will be. That is to say, the brighter the lamp, the higher the luminous efficiency of the luminaire. When the luminous flux of the luminaire is constant, the luminous efficiency is inversely proportional to the rated power of the luminaire.
Luminous efficiency is an important indicator to measure the efficiency of lamps. Whether a led lamp is done well, this is an important reference indicator. High luminous efficiency means that
1. Its power conversion efficiency is high, and the heating is low, which is beneficial to the life of the lamp;
2. It is also possible that the light efficiency of the LED lamp chip is also high, and the large chip used;
3. It is also possible to use a large number of lamp beads to ensure that the lamp beads work at a low current;
4. At the same time, the light transmittance of the lamps may also be high. These comprehensive indicators must be improved at the same time to increase the light efficiency. To a certain extent, it reflects the comprehensive ability of the manufacturer.
