characteristic
The LD11 series indicator lights all use LED chips as the light source, which have low energy consumption, high height, low temperature rise, and long service life. Taking XD5 and 220V signal lights as an example, their power consumption is 20.86 watts, while our developed A-type, B-type and other indicator lights have a power consumption of only 2.7 watts for resistive lights and 0.59 watts for capacitive lights. If calculated based on 8000 working hours per year, each resistive indicator light can save 145 kWh of electricity per year, and the capacitive indicator light can save 162 kWh of electricity. Especially, the capacitive indicator light not only saves electricity, but also has benefits for improving the power factor of the power supply line. Not only that, but it also has a long service life, able to work continuously for 30000 hours, which is 5 to 6 times that of incandescent neon lamps. Users can save money once and for all, greatly reducing maintenance costs.
2. The wide power supply voltage can operate normally within ± 20% of the rated voltage.
3. It is resistant to vibration and impact, and can work normally under vibration frequencies (sine) of 10~2000Hz, 1.5mm, and 10g. It solves the problem of easy breakage of tungsten wire in light bulbs and high maintenance costs, greatly improving the reliability of the product and facilitating users.
4. It has high safety performance and is easy to use. The conductors are hidden inside the shell, and combination screws are used to press the wires, which is convenient for users and saves wiring time.
5. Small size, light weight, and good performance. The shell is made of high-performance flame-retardant engineering plastic, which not only makes the product small and exquisite, with a net weight of only 22 grams per piece, but also improves the mechanical strength, high temperature resistance, and flame-retardant performance of the product, making it more suitable and safe, and meeting the needs of users.
6. The product has a beautiful appearance, diverse varieties, bright colors, soft lighting, and can be installed on equipment for various purposes such as indication, decoration, and lighting.
7. Good interchangeability. Due to its innovative design, this product can be installed on? 2 or? On the installation hole of 5, it not only meets the supporting needs of the exporting country, but also meets the maintenance requirements of the original old equipment.
8. The product has high protection performance, with a front protection level of IP65, thus meeting the requirements of users in various industries
