HX4086 is a multi-segment LED constant current driving chip with temperature compensation function. It achieves constant current accuracy of less than ±5% through proprietary technology. The output current can be adjusted by external resistors. The chip has high power factor and low harmonic distortion. The chip adopts 700V withstand voltage and impact resistance. It does not need transformers and high-voltage electrolytic capacitors. It is the current constant-current driver chip with the lowest peripheral components and low system cost. The LED lamp driven by this chip is used. Can be used in thyristor controlled dimming.
To ensure the life of the LED, a constant current drive circuit must be used. Existing constant current drive circuits require high frequency transformers or high voltage electrolytic capacitors. The LED lighting device has a relatively large temperature rise, and the service life of the electrolytic capacitor in the high temperature environment is greatly shortened, which is far shorter than the life of the LED itself, which is not conducive to the large-scale application of the LED lighting product, and the driving scheme has the LED The same life of the wick.
Features:
1. The power efficiency is greater than 90% and the power factor is greater than 0.9.
2. With temperature compensation, over temperature protection.
3. The lamp bead utilization is high, and the strobe is improved.
4. Applicable to electronic dimmer and thyristor dimming.
5. Directly exchange 110/220V AC input with minimal external components.
6. IC and LED share aluminum substrate, wick is integrated, no electrolytic capacitor, IC and LED have the same life.
7. The overall application plan is certified by safety, CE, EMC and UL.
Program features:
Not the most perfect, but it is the best mass production cost-effective solution, reducing manual work, improving production efficiency, reducing production costs, reducing overall BOM cost, fewer components, IC and LED with the same life, higher reliability, is Domestic mainstream power solution.
The development of switching power supply has reached its limit, and its cost can no longer be reduced. If the photoelectric integrated module of Huaxin AC-LED driver IC is adopted, it not only surpasses the AC/DC scheme in performance, but also has absolute advantages in cost. The system cost of the entire lamp will drop by about 30%. In addition, based on mechanized production, the defect rate will be greatly reduced. With fully automated patch production, the production capacity and production cost of the photoelectric engine will also be greatly reduced.
CAM Lock
Cam lock, as the name implies, is Mechanical key lock. Our mechanical lock series products are divided into 12mm, 16mm and 19mm according to size also could be divided into Cabinet CAM Lock with keys and Drawer CAM Locks without keys.The Key Switch has 2 positions and 1 keypull or 2 keypulls.All key alike or combination available.Hex nut mounted.
This cam lock cover a wide range of applications and can be used in large entertainment equipment, like ,vending machines, mechanical equipment, lockers, ATMS etc.
We have introduces high-precision CNC numerical control milling machine and multiple automatic processing equipment at home and abroad to improve cam lock` s precision,insuring all the cam lock cant be replaceable or copy. The specification is as follows:
