摘要:
A lens includes a convex surface formed in an outer surface thereof facing away from a light source to uniformly distribute light emitted from the light source; a concave surface concaved inward from an inner region of the convex surface, around an optical axis; and a convex portion convexed outward from a central region of the concave surface, which the optical axis intersects, in order to enhance quantity of light around the optical axis. The lens refracts light beams falling onto the respective areas thereof at different angles, thereby producing a uniform light distribution within a specific lighting range, but does not create a dark area around an optical axis.

The invention provides an LED package and a backlight device incorporating the LED lens. The LED package has a bottom surface and a light exiting surface cylindrically extended around a central axis of the package from the bottom surface. Also, a reflecting surface is positioned on an opposite side of the bottom surface and symmetrical around the central axis such that light incident from the bottom surface is reflected toward the light exiting surface. Further, a scattering area is formed on the reflecting surface. According to the invention, by applying scattering materials on the reflecting surface of the LED package, a reflecting paper does not need to be attached, thereby simplifying a process and reducing the manufacture time and cost.

A method of providing a PoC service service in a mobile communication system is disclosed, by which a user's sensory duration can be reduced in case of switching a status of a traffic channel between a user equipment and a mobile communication network to an active mode from a dormant mode in the mobile communication system such as a CDMA network. The present invention includes a first step of transmitting the PoC service data from a first user equipment in the dormant mode via a short data burst, a second step of allowing the user equipment to enter an active mode via a traffic channel connection after completion of the first step, a third step of transmitting a reception acknowledgement signal (ACK) from a second user equipment having received the PoC service data via the short data burst, and a fourth step of receiving the reception acknowledgement signal (ACK) via a traffic channel.

A light guide plate of an LED backlight unit is disclosed. The light guide plate comprises a pair of wide planes facing each other, and a narrow plane formed between the pair of wide planes and constituting a thickness of the light guide plate. The narrow plane has an incident plane formed on a section of the narrow plane facing the LED light source, and one of the wide planes constitutes an exiting plane from which light entered from the LED light source exits. The incident plane has a plurality of elliptic cylinder-shaped grooves carved into the incident plane in a thickness direction of the light guide plate. As such, the elliptic cylinder-shaped grooves are carved into the incident plane of the light guide plate in the thickness direction, widening an incidence angle of which light can be transmitted therethrough.

A sensor for measuring heat generated from cells, including a thermopile manufactured by surface-micromachining technology, and a microfluidic flow-channel structure for mixing cells with medium and dividing the mixture into cells and medium. Medium and cells are uniformly mixed using a micro-mixer. The mixture is separated into a medium microfluid and a cell microfluid using the Zweifach-Fung effect, after which signals measured in the two microfluids are amplified. The difference between the two signal values determines the amount of heat generated from the cells. The influence of noise caused by a change in external environment is eliminated. Convection heat dissipation caused by fluid flow is minimized. The sensor accurately measures the amount of heat generated from cells flowing in the microfluidic flow-channel. Diseases such as cancer are diagnosed using the difference between the measured amount of heat generated from cells and the standard amount of heat generated from normal cells.
