Table lamps are mainly placed on desks or dining tables for lighting purposes. Among them, LED desk lamps are favored by more and more consumers because they are beautiful and practical. So what is an LED desk lamp? What factors affect the price of LED desk lamps? Let’s follow us to find out more.
What is an LED desk lamp?
LED desk lamp is a desk lamp that uses LED (Light Emitting Diode) as the light source. LED is a solid-state semiconductor device that can directly convert electricity into light. The LED lighting technology it uses is the third generation lighting technology. The blue light produced by the use of LED desk lamps can cause damage to the eyes, but it also has a series of advantages.
What factors affect the price of LED desk lamps?
When consumers purchase LED desk lamps, they may generally be misled by the appearance of LED desk lamps and thus determine their own price outlook. In fact, this is not the case. There are seven major factors that truly determine the price of LED desk lamps:
1. The chips used in LED desk lamps are different: there are domestic and Taiwanese chips as well as imported chips. Different chips have huge price differences. Currently, the most expensive American chips are followed by Japanese chips and German chips. The lowest-priced Taiwanese chips have slightly poorer heat dissipation performance.
2. LED packaging is different: resin packaging and silicone packaging. Resin encapsulation is cheaper. Everything else is the same. Silicone encapsulation has good heat dissipation performance, so the price is slightly more expensive than resin encapsulation.
3. Whether the LED colors are consistent: There are many packaging factories in China. There are thousands of large and small companies in total, and of course there are strong and weak ones. There are many small packaging factories that do not have spectroscopic and color separation machines, so they either do not perform spectroscopic and color separation, or they send them out, which makes it difficult to guarantee quality;
4. Differences in LED welding effects: LED lights There are two types of belt assembly: manual welding and machine welding. Manual soldering is to use a soldering iron and use the most primitive method to solder. The products produced in this way have an ugly appearance and poor electrostatic protection measures. Many LED chips have been broken down, resulting in a faint or no light when powered on. Machine welding uses reflow soldering, but machine welding is different. Not only does the soldered product look beautiful, but the chip will not be burned out by static electricity. At the same time, the LED position and direction are more beautiful.
5. FPC material: FPC is divided into rolled copper and clad copper. Copper-clad laminates are cheaper, and rolled copper is more expensive.
6. Whether the LED desk lamp has a patent: Patented ones are more expensive, while non-patented ones are cheap.
7. LED brightness: LEDs with different brightness have different prices. There is a huge price difference between ordinary brightness and high brightness LEDs.
