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 microcrystalline glass by utilizing blast furnace steel slag

The invention relates to a method for preparing a microcrystalline glass by utilizing steel slag. The method comprises the following steps of: firstly, carrying out drying and ball milling on the steel slag and removing iron contained in the steel slag to prepare powder of 100 meshes; then mixing the steel slag powder, quartz sand, sodium nitrate, barium nitrate, zinc oxide and cerium dioxide into a compound material; placing the mixture obtained from the former step into a crucible, and smelting at 1250-1380 DEG C to form a transparent steel slag glass; and finally, crystallizing the transparent steel slag glass to form the steel slag microcrystalline glass containing calcium akermanite as a main crystal phase. The method disclosed by the invention utilizes the blast furnace steel slag as a main raw material and achieves the utilization amount of the steel slag at 96%; and the microcrystalline glass prepared according to the method has the advantages of high structural strength, low water absorption, high crystalline degree and various color. The preparation process disclosed by the invention is simple in operation process and low in cost, can effectively reduce the production cost of the microcrystalline glass, protects the environment and changes the wastes into valuables, is suitable for industrialized large-scale production and has obvious economic benefit and environmental benefit.
