  • Patent number: 9312954
    Abstract: A light communication system, a transmitter and a receiver are provided. The light communication system includes the transmitter and the receiver. The transmitter has a first processing unit and a light-emitting element. The first processing unit produces a transmission signal. The light-emitting element produces light to carry the transmission signal. The receiver has a first variable lens, a photosensitive element and a second processing unit. The first variable lens changes the propagation path of the light. The photosensitive element senses the light passed through the first variable lens to produce a receiving signal. The second processing unit controls the first variable lens based on the signal quality of the receiving signal to change the equivalent channel between the transmission signal and the receiving signal. Therefore, the transmission capability of the light communication system is enhanced.

  • Patent number: 8636381
    Abstract: A flexible light source module including a flexible substrate, a flexible light guide film and a plurality of point light sources is provided. The flexible light guide film including light-guiding portions is disposed on the point light sources. Each of the light-guiding portions includes a light incident surface and a light emitting surface. The light incident surface includes light incident sub-surfaces. The light emitting surface includes light emitting sub-surfaces, and the one closest to the geometric center of the light-guiding portion is a first light emitting sub-surface. The absolute values of the tangent slopes of the first light emitting sub-surface are ascending with approaching the geometric center of the light-guiding portion. The light beams emitted from the point light sources exit out of the flexible light source module via the flexible light guide film so that the flexible light source module provides a uniform planar light source.

  • Publication number: 20130107545
    Abstract: A bulb cap is mounted on a base and includes an elastic translucent cap and a gas injecting device. The elastic translucent cap has an initial geometric shape and a thickness-distribution structure. The gas injecting device is coupled to the elastic translucent cap. After the elastic translucent cap is mounted at the base, gas with a gas-pressure can be injected by using the gas injecting device so that the elastic translucent cap is expanded to a geometric shape structure corresponding to the gas-pressure to change a light pattern of the base, and meanwhile the geometric shape structure is varied with the gas-pressure. In addition, the elastic translucent cap can be replaced by a bulb cap with a fixed geometric shape.
