New COB light source for fluorescent tubes

The traditional LED fluorescent tube is generally packaged with a small and medium power TOP type light source, which has low light efficiency, high packaging cost and application cost, and complicated manufacturing process. In order to break the traditional packaging and assembly methods, Zhen Mingli introduced the TB (T5 or T8) fluorescent tube COB- AK14 package structure, COB source light efficiency up to 160Lm / W, the overall lighting efficiency of 135Lm / W; packaging cost and Low application cost; low thermal resistance and good reliability; easy to assemble and apply.
Light effect: The aluminum substrate is directly used to form a full metal and independent cup structure, and the vacuum coating technology is adopted to improve the light reflectance, thereby improving the light output efficiency of the LED and greatly improving the Lm/RMB cost performance.




Package cost and application cost: The new COB structure saves material costs such as brackets, PCB boards, solder paste, etc., reflow soldering machine cost, patch and soldering process, and the overall cost of the whole lamp will drop by about 40%.



Low thermal resistance and good reliability: the new COB heat dissipation channel is more direct, directly from the chip → solid crystal glue → aluminum substrate, while the traditional SMD light source is applied to the fluorescent tube, the thermal resistance is higher, the heat dissipation channel is from the chip → solid crystal glue → bracket → PIN foot → solder paste → aluminum substrate; and COB package structure is airtight.


Easy to assemble and apply: COB-AK47 is connected mechanically and electrically by connecting terminals. Direct card can be inserted into the lamp heat sink, as shown below:

LED fluorescent tubes have become a trend in indoor lighting in the 21st century and have become the mainstream in the field of lighting.

Manual Light Tower

A manual light tower is a portable lighting system that is operated manually. It is typically used in construction sites, outdoor events, emergency situations, and other areas where temporary lighting is needed.

Here are some key features and components of a manual light tower:

1. Light Fixtures: A manual light tower usually consists of multiple light fixtures mounted on a telescopic mast. The number and type of light fixtures can vary depending on the model and purpose of the tower.

2. Mast: The mast is the vertical structure that supports the light fixtures. It is typically made of steel or aluminum and can be extended or retracted manually to adjust the height of the lights.

3. Generator: Most manual light towers have an integrated generator to provide power to the light fixtures. The generator is usually powered by gasoline, diesel, or propane.

4. Control Panel: The control panel is used to start and stop the generator, control the intensity of the lights, and adjust other settings. It is typically located near the base of the tower for easy access.

5. Mobility: Manual light towers are designed to be portable and easy to move around. They are often equipped with wheels or a trailer hitch for towing.

6. Stabilization: To ensure stability, manual light towers are equipped with stabilizing legs or outriggers that can be extended to provide a solid base.

7. Durability: Manual light towers are built to withstand harsh outdoor conditions. They are typically made of heavy-duty materials and have weather-resistant coatings.

8. Manual Operation: Unlike automated light towers, manual light towers require manual operation for adjusting the height, turning on/off the lights, and starting/stopping the generator.

9. Lighting Options: Manual light towers can be equipped with different types of light fixtures, such as metal halide, LED, or halogen lights. The choice of lighting depends on the specific requirements of the application.

10. Safety Features: Manual light towers often have safety features such as emerg
