The cultural and tourism water patterns project the three-dimensional water flow effect, which is similar to the special effects of water ripples, creating a beautiful…

Advantages of fiber optic lights compared to traditional lamps

Uncategorizedsfyh
Fiber optic chandelier is a new type of lamp, with unique shape and individual design, wide creative space, it integrates high-brightness side-emitting plastic optical fiber cable into a bundle, one or both ends are equipped with high-brightness colorful fiber optic light engine, electronically controlled under the action of the device, 8 different colors can be changed, and the color can also be selected according to personal preference. Through processing, the light generated by the optical fiber does not contain ultraviolet rays and infrared rays, and the optical fiber itself is non-conductive, and the safety performance is high. Fiber optic lighting…

What is the difference between constant current and constant voltage LED drivers?

LED Power Supplysfyh
led driver constant current are designed to specify a range of output voltages and a fixed output current (mA). LEDs rated to operate on constant current drivers require A specified current supply, usually in milliamperes (mA) or amperes (A). Constant current LED drivers have similar power ratings, but have fixed amplifier (a) or milliampere (MA) values for voltage or maximum voltage range. LED equipment shall display its power requirements and rated voltage and current range. If it is only led, current control must be carried out to prevent led thermal runaway. led driver constant voltage usually have fixed rated voltage…

YTPQC-APF in Hospital

Uncategorizedsfyh
Hospitals are places where reliable power distribution is needed to guarantee patient health and save lives. Continuity and reliability of power supply are extremely important. Automatic power restoration time of different healthcare venues is as follows: category 0 venues t≤15s; category 1 venues 0.5s≤t≤15s; and category 2 venues t≤0.5s. The Solution ofYTPQC-APF Harmonics affect lighting stability and interfere with precision medical instruments such as CT scanners, MRI scanners and ECGs, reducing examination accuracy and ultimately affecting physician diagnoses of patients’ conditions. In addition, high volumes of harmonic current also reduce the stability.There are some harmonic problems in Building 3 of…

IP67 waterproof rating standard definition

LED Power Supplysfyh
IP rating is an international standard for measuring the dust and water resistance of equipment. In the two-digit IP code, the first digit represents the level of protection against ingress of foreign objects, including dust. The second number indicates the waterproof rating of the device. The IP rating achieved must be certified and independently tested before it can be indicated on the product description. IP6X-completely sealed to prevent the intrusion of foreign objects and dust. IPX7 – Resists immersion in 1 meter deep water for 30 minutes. Under normal circumstances, the IP65 level of LED waterproof power supply can meet…

Wired barcode scanner and wireless barcode scanner

barcode scannersfyh
Barcode Scanner can be divided into wired barcode scanner and wireless barcode scanner. The wired barcode scanner, as the name suggests, transmits data to a computer or POS machine through a data cable. Wireless barcode scanner, also known as cordless scanner. Generally, data is transmitted through bluetooth, wifi, etc., and the data can be transmitted without the limitation of the length of the data cable, which is more convenient to use. In terms of price, wireless barcode scanner are higher than wired barcode scanner. A wireless barcode adapter is a product that can convert a wired barcode scanner to a…

What conditions must be met for the constant current led driver 110v to support the hot swap of lamps when powered on？

LED Power Supplysfyh
What is hot swap?Hot swappig or Hot plugging) is “hot plugging”, which means that the led driver 110v plugs or unplugs the load lamps at the output end when the input end is powered on. 1. The maximum output voltage of the led driver enclosure box (no-load voltage) = the input voltage of the lamp, if the no-load voltage of the led driver enclosure box is 60V, the input voltage of the lamp is also 60V 2. The output current of the 24 volt 20 watt led driver, the lamp can withstand, such as the output of the  led driver enclosure box  500mA, the current the…

Why do LED lights in the home get dimmer with more use?

LED Power Supplysfyh
It is a very common phenomenon that LED lights become dimmer as they are used. In addition to light decay, the reasons for dimming LED lights are nothing more than the following two points. 1. The drive is damaged LED lamp beads are required to work at low DC voltage (below 20V), but our usual mains is AC high voltage (AC 220V). To turn the mains into the electricity required by the lamp beads, a device is needed, called “LED drive power“. Theoretically speaking, as long as the parameters of the driver match the lamp bead board, the power supply…
