The UVLED point light source curing system enables the LED high-power UV diode chip to produce high-purity 365nm monochromatic UV light through the conversion of electrical to light energy. The energy is highly concentrated. UV curing required wavelength range. Its main features are: product service life It has long curing time, low cost, no mercury, and only requires ordinary cables. It is a replacement product for the traditional fiber optic high-pressure mercury lamp point light source machine. Scope of application: UV glue , shadowless glue curing, electronics, precision parts, DVD movement /It has a wide range of applications in optical heads, optical lenses, liquid crystal display panels, micromotors, medical applications, handicrafts, fiber optic connectors, liquid crystals, LCDs, motors, hard drives and other emerging fields. 1. The difference between UVLED point light source and traditional high-pressure mercury lamp curing equipment
(1): The UV light generated by traditional curing machines looks very bright and has high heat. In fact, its spectrum is very wide. A certain UV spectrum segment that is actually effective in curing only accounts for a part of its energy. A considerable part is in the visible light segment (stray light) and generates heat, which seriously damages the operator's eyes and easily causes thermal deformation of the workpiece. (2): UV-LED point light source emits high-purity 365nm monochromatic ultraviolet light. It is a cold light source； The temperature of the workpiece only rises 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, so that during curing time is shortened to 0.5 to 5 seconds. 2. UVLED point light sources significantly reduce production costs (1): LED curing equipment generates almost no heat, is not fragile, and does not contain mercury； Maintenance costs are low. (2): The LED irradiation head is controlled by a computer. You can choose manual or automatic control operation according to actual needs, and set the time required for light irradiation (accurate to 0.01S) to further support high-precision joining requirements and reduce the time error of human operation. (3): The LED point light source is small and lightweight, and can be easily integrated into the automatic assembly process or used as a complete desktop system. (4): Due to the LED light-emitting method, the life span is more than 25,000 hours (continuous ignition life). It adopts an energy-saving design and only lights up when illumination is needed. It consumes low power and has a power of about 50W.
