[High-tech LED News] Jingtai Optoelectronics has recently created a "three high" high-power LED package with high brightness, high luminous efficiency and high color rendering index. The new product adopts K1 type package and adopts metal reflector in the packaging process. The structure enables the back-illumination efficiency of the LED chip to be fully applied, thereby reducing the luminous loss and saving cost.
The product is optimized for one-shot silicone lens, the light utilization rate can reach 90%, combined with the innovative surface roughening technology, to solve the LED spot problem from the light source to ensure the application effect. In addition, the new product has excellent static protection function, the process is in line with ROHS standards, and it can safely pass the reflow soldering process.
The new product adopts high-efficiency high-power LED chip from abroad, which has high luminous efficiency and good stability. Under 25° room temperature, the light decay can be controlled within 3,000 hours of 3,000 hours. It can be used for LED general illumination such as bulbs, PAR lamps and other energy-efficient white lamps with specifications E12/E14/E26/E27/GU10.

Powerbanks are popular for charging smartphones and mobile tablet devices. A powerbank is a portable device that can supply power from its built-in batteries through a USB port. They usually recharge with USB power supply. Technically, a powerbank consists of rechargeable Lithium-ion or Lithium-Polymer batteries installed in a protective casing, guided by a printed circuit board (PCB) which provides various protective and safety measures. Due to its general purpose, powerbanks are also gaining popularity as a branding and promotional tool. Different brands and promotional companies use it as a promotional tool and provide a customized product.
Specifications:
Capacity in mAh: mAh stands for milli Ampere-hour and measures the amount of power flow that can be supplied by a certain powerbank at a specific voltage. Many manufacturers rate their products at 3.7 V, the voltage of cell(s) inside. Since USB outputs at 5 V, calculations at this voltage will yield a lower mAh number. For example, a battery pack advertised with a 3000 mAh capacity (at 3.7 V) will produce 2220 mAh at 5 V. Power losses due to efficiency of the charging circuitry also occur.
Simultaneous charging and discharging: need to specify if the powerbank can be used while it is charging.
Number of output USB ports: This specifies the number of devices that can be charged simultaneously.
Output current rating: This specifies the current rating that it can charge maximum. The higher the number, the better the powerbank. This can vary from output port to output port.
Input Current Rating: Input current rating is the amount of current the powerbank is able to draw at its maximum level while getting charged.
Safety Protections: Over Voltage Protection, Over Charge Protections, Over Current Protections, Over Heat Protections, Short-Circuit Protections and Over Discharge Protections are the common safety measures observed with standard powerbanks.
LED Indications: The Led glows as per indicating the amount of charging ability left with the powerbank.
