Comprehensive analysis of why UV LED light sources are superior to traditional mercury lamps

 The UV  LED point light source curing system converts electrical to optical energy to enable the LED high-power ultraviolet diode chip to generate high-purity 365nm monochromatic ultraviolet light, and the energy is highly concentrated in the wavelength band required for UV curing.

　　Advantages of UV LED light source technology over traditional mercury lamp

　　Its main features are: long product life, fast curing time, low cost, no mercury, and only ordinary cables are needed. It is a replacement product for the traditional optical fiber high-pressure mercury lamp point light source machine.

　　Scope of application: UV glue/shadowless glue curing, electronics, precision parts, DVD movement/optical head, optical lenses, liquid crystal display panels, micromotors, medical use, handicrafts, optical fiber connectors, liquid crystal, LCD, motors, hard disks and other emerging fields.

　　1. The difference between UV LED point light source and traditional high-pressure mercury lamp curing equipment

　　A: The UV light produced by traditional curing machines looks very bright and has high heat. In fact, its spectrum is very wide. Only a part of its energy is in a certain ultraviolet spectrum segment that has an effective curing effect. A considerable part of it is in the visible light segment (stray light) and generates heat, which can cause serious damage to the operator's eyes and easily cause thermal deformation of the processed workpiece.

　　B: UV LED point light source, which emits high-purity 365nm monochromatic ultraviolet light, is a cold light source; the temperature of the workpiece only rises by about 3 degrees, and the workpiece will not deform. Its energy is highly concentrated in a certain ultraviolet spectrum segment with effective curing effect. The actual use effect is comparable to the curing effect of a high-pressure mercury lamp with a light intensity of 1000-2000mw, shortening the curing time to 0.5 to 5 seconds.

　　2. UV LED point light source greatly reduces production costs

　　A: Due to the LED light-emitting mode, the life span is more than 25,000 hours (continuous burning life). It adopts energy-saving design and only lights up when it is needed. It has low power consumption and power consumption is about 50W.

　　B: LED point light source is small and light, and can be easily integrated into the automatic assembly process or used as a complete desktop system.

　　C: The LED irradiation head is controlled by a computer. You can choose manual or automatic control operation according to actual needs, and set the required light irradiation time by yourself (accurate to 0.01S) to further support high-precision joining needs and reduce the time error of manual operation.

　　D: LED curing equipment generates almost no heat, is not fragile, does not contain mercury, and has very low maintenance costs.

　　3. The special focusing lens assembly equipped with UV LED also makes its energy highly concentrated on the curing point, improving the curing efficiency. It can irradiate in 4 ways (each device can be equipped with 4 LED tubes) at the same time to increase the area.

　　4. No preheating is required, and high-energy ultraviolet light is emitted instantly. The latest high-energy 365nm ultraviolet LED is used to emit high-energy ultraviolet light instantly, quickly completing the curing of ultraviolet glue and greatly improving production efficiency.
