[UVLED Wire Light Source] the Characteristics of the Light Spots of UVLED Line Light Sources

The definition of each manufacturer of UVLED line light sources is different, generally refers to a light source with a width of light less than 10mm or 15mm, and unlimited length. UVLED line light sources generally arrange UVLED into a row, and add a round stick -like or semi -circular quartz lens in the UVLED light -emitting direction, so that the round light spots emitted by each UVLED are stretched into oval spots through the lens. The strength of the light at the center of the light spots is stronger than the two wings of the ellipse, but as long as the two adjacent LEDs are discharged properly, the two wings of the adjacent oval light spots overlap each other, so that the strength of the light of the two wings will be strengthened, and the strength of the two wings will be enhanced. Direction) Forms a relatively uniform light intensity. As shown in the figure below: In the short shaft (light spots width direction), because there is no effective superposition effect, it will present the high -sides of the high side of the middle and low parabolic light intensity curves. Of course, we can change the shape of the parabolic line through the luminous angle of the lamp beads or the diameter of the lens. The picture below shows the light intensity curve of the long axis and short shaft direction in a certain line (blue and red represents different light beads with different luminous angles): the long shaft) The light intensity of the light intensity in the direction of the direction
