Abstract
A portable reading lamp includes a lower and an upper cover assembled together to enclose therein a printed circuit board (PCB), a plurality of light-emitting units, a laser-illuminating unit, a power supply unit, and switches for switching on and off the light-emitting units and the laser-illuminating unit. The assembled lower and upper covers define an inward curved front surface, from where the light-emitting units irradiate light onto a predetermined area to help in reading at a dark place without the need of a light-guiding plate, enabling a largely reduce size of the portable reading lamp. With the laser-illuminating unit, the portable reading lamp may serve as a laser pointer. And, magnets may be externally attached a bottom of the lower cover, enabling the portable reading lamp to serve as a magnetic memo holder.
Claims13
A portable reading lamp, comprising:
- a printed circuit board (PCB) with a predetermined circuit layout provided thereon;
- a lower cover located below the PCB;
- an upper cover assembled to a top of the lower cover to enclose the PCB in and between the lower and the upper cover;
- a plurality of light-emitting units spaced on one side of the PCB to electrically connect to the PCB;
- and
- a switch unit and a power supply unit provided on the PCB to electrically connect to each other;
- and
- the lower cover having an elongated configuration with two long sides thereof formed into two concaved surfaces, and being internally provided with fixing members for fixing the PCB to an inner side of the lower cover;
- the upper cover also having an elongated configuration corresponding to that of the lower cover, and being formed with a plurality of holes corresponding to the light-emitting units as well as two opposite slits corresponding to the switch unit, such that the light-emitting units are respectively aligned with and confined in one corresponding hole and the switch unit is aligned with and confined between the two slits;
- and
- the assembled upper cover and lower cover together defining a front surface formed into an inward curved lighting surface, from where the light-emitting units irradiating light onto a predetermined area.
