Comprehensive analysis of UV LED light source is better than traditional mercury lamp

OFwee Semiconductor Lighting Network UV LED point light source curing system is through the conversion of electricity → light energy, LED high power UV diode chip produces high purity 365nm monochromatic ultraviolet light, the energy is highly concentrated in the wavelength range required for uv curing.

Advantages of UV LED light source technology compared to traditional mercury lamps

Its main features are: long product life, fast curing time, low cost, no mercury, only ordinary cable, is the replacement of traditional 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 lens, liquid crystal display panel, micro motor, medical, handicraft, fiber optic connector, LCD, LCD, motor, hard disk and others There are a wide range of applications in 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 the traditional curing machine looks very bright and has a high heat. In fact, its spectrum is very wide. It is only a part of the energy in the UV spectrum of effective curing. A considerable part is in visible light. Segments (stray light) and heat generation are severely damaged to the operator's eyes and are prone to thermal deformation of the machined workpiece.

B: UV LED point light source emits high-purity 365nm monochromatic ultraviolet light, which belongs to cold light source; the workpiece temperature rises only about 3 degrees, the processed part does not deform, and its energy is highly concentrated in an ultraviolet spectrum with effective curing effect. The actual use effect and the high-pressure mercury lamp with a light intensity of 1000-2000 mw are similar to each other, and the curing time is shortened to 0.5 to 5 seconds.

2, UV LED point source significantly reduces production costs

A: Due to the LED light-emitting method, the life span is more than 25,000 hours (continuous ignition life). It adopts energy-saving design and only lights up when it needs to be illuminated. The power consumption is low, and the power is about 50W.

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

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

D: LED curing equipment generates almost no heat, is not brittle, does not contain mercury; maintenance costs are low.

3, UV LED equipped with a special condenser lens assembly also makes its energy highly concentrated on the curing point, improve the curing efficiency, can be 4 channels (each device can hold 4 LED tubes) with the same radiation to increase the area.

4, no need to preheat, instantly emit high-energy ultraviolet light, using the latest high-energy 365nm ultraviolet LED, instantly emit high-energy ultraviolet light, quickly complete the curing of UV glue, greatly improve production efficiency.
