Retrofit LED lamp for fluorescent fixtures without ballast

An energy saving device for an LED lamp mounted to an existing fixture for a fluorescent lamp where the ballast is removed or bypassed. The LEDs are positioned within a tube and electrical power is delivered from a power source to the LEDs. The LED lamp includes means for controlling the delivery of the electrical power from the power source to the LEDs, wherein the use of electrical power can be reduced or eliminated automatically during periods of non-use. Such means for controlling includes means for detecting the level of daylight in the illumination area of said least one LED, in particular a light level photosensor, and means for transmitting to the means for controlling relating to the detected level of daylight from the photosensor. The photosensor can be used in operative association with an on-off switch in power connection to the LEDs, a timer, or with a computer or logic gate array in operative association with a switch, timer, or dimmer that regulates the power to the LEDs. An occupancy sensor that detects motion or a person in the illumination area of the LEDs can be also be used in association with the photosensor and the computer, switch, timer, or dimmer, or in solo operation by itself. Two or more such LED lamps with a computer or logic gate array used with at least one of the lamps can be in network communication with at least one photosensor and/or at least one occupancy sensor to control the power to all the LEDs.

Method for preparing graphene or graphene oxide by using high-efficiency and low-cost mechanical stripping

The invention provides a method for preparing graphene or graphene oxide by using high-efficiency and low-cost mechanical stripping and relates to a preparation method of the graphene or the graphene oxide, solving the problems that the traditional micro-mechanical stripping method has low efficiency and can not be used for large-batch production. The method comprises the following step of separating carbon materials by utilizing solid particles and a liquid working medium (or gas working medium) and adopting mechanical stripping to obtain the graphene or the graphene oxide, wherein the carbon materials comprise graphite powder, expanded graphite, expandable graphite or graphite powder oxide. By using automatic machinery and using a great deal of solid particles for assisting stripping processes, the invention greatly increases the contact areas and the stripping times of the stripping processes, the carbon materials are subject to a great amount of stripping processes in a short time through the shearing and impacting functions of the solid particles on the carbon materials, and thereby the method obviously improves the stripping efficiency, has low cost and is suitable for the industrial and large-batch production of the graphene or the graphene oxide.

Power controls with photosensor for tube mounted LEDs with ballast

A power saving device for a light emitting diode (LED) lamp mounted to an existing fixture for a fluorescent lamp having a ballast assembly and LEDs positioned within a tube and electrical power delivered from the ballast assembly to the LEDs. The LED lamp includes means for controlling the delivery of the electrical power from the ballast assembly to the LEDs wherein the use of electrical power can be reduced or eliminated automatically during periods of non-use. Such means for controlling include means for detecting the level of daylight in the illumination area of said least one LED in particular a light level photosensor and means for transmitting to the means for controlling a control signal relating to the detected level of daylight from the photosensor. The photosensor can be used in operative association with an on-off switch in power connection to the LEDs, or with a computer or logic gate array in operative association with a dimmer that controls the power to the LEDs. An occupancy sensor that detects motion or a person in the illumination area of the LEDs can be optionally used in association with the photosensor and the computer and dimmer. Two or more such LED lamps with one or more computers or logic gate arrays can be in network communication with the photosensors and the occupancy sensors to control the power to the LEDs.
