A light pen with multicolor light sources comprise a pen holder and a pen body wherein the pen body which slips on the pen holder can generate multicolor light sources, and the pen body further comprises a multicolor Light Emitting Diode (LED), a housing, and a conductive stand wherein the LED and the conductive stand are installed respectively at both ends of the housing. By turning the knob on the conductive stand, the conductive piece therein timely contacts the positive leads of different chips of LED in order to make the multicolor LED timely generate multicolor light sources to facilitate the convenient usage of light pen.

Light pen with multicolor light sources

An improved structure of a laser indicator includes an outer tube, a cover cap, a focus adjusting device, an optical lens, and a circuit board having a laser diode disposed thereon. The outer tube and the cover cap are joined to form a rod-shaped indicator housing. The optical lens and the laser diode are provided inside the focus adjusting device, which is comprised of an inner cover and an outer cover working in conjunction with a metallic spring. The laser diode is fittingly disposed inside the inner cover, while the outer cover is screwably connected to the outer cover. The spring is disposed between the inner cover and the optical lens. One end of the outer cover is screwably coupled to the cover cap, while the other end thereof forms a smooth holding surface to facilitate turning of the outer cover in focus adjustment. The arrangement of the spring ensures the positioning of the optical lens and forms a bridge for the conduction of electric currents between the outer and inner covers, thereby avoiding the problem that the inner cover is isolated from the outer tube after it is coated with a fixing glue.
