Point light source is generally a UVLED lamp beads (mostly single-core, but also multi-chip) issued by the light, forming a point, known as the point light source
Line light source is generally more than one UVLED lamp beads (but also integrated chip) rows in a line, emitting a linear light, forming a line, known as the line light source
Surface light is a UVLED lamp beads in accordance with different combinations to form a multi-line. According to different combinations of forms to form multiple rows and columns, emitting a variety of shapes of the surface of the light, forming a surface, known as the surface light source.
Currently, point light source \ line light source has been widely used, mainly low cost, and technically good to achieve, heat dissipation is generally used in the heat sink module + air-cooled mode, the drive is not complex:○ hard disk head assembly (gold wire fixing, bearings, coils, chip bonding, etc.)
○ motor and component assembly (wires, coils, coil fixing, coil end fixing, PTC / NTC component bonding, protection transformer core) Motor and component assembly (wire, coil fixing, coil end fixing, PTC/NTC component bonding, transformer core protection)
○DVD/Digital Camera (lens, lens bonding, circuit board reinforcement)
○Sensor production (gas sensors, photoelectric sensors, fiber optic sensors, optical encoders, etc.
○Mobile Phone Component Assembly (Camera Lens, Earpiece, Microphone, Shell, Liquid Crystal Module, Touch Panel Coating, etc.)

Surface light source is different, a lot of lamp beads integrated together, the solution to the problem of heat dissipation is a big problem, but also so much lamp beads, the driver is also a headache, so many companies only point light source and line light source for the surface light source do not dare to get involved is the reason. Surface light sources do not dare to get involved is the reason.
My company and the U.S. SET company jointly developed UV LED surface curing machine, curing speed than the traditional UV oven 10 times faster than the curing of individual parts, surface curing up to 210 * 210mm face (as long as 2 ~ 5 seconds, UV glue nature of the speed of the different differences), such a large area of the light source in the country only one of us.
