2results about How to "Reduce weight and size" patented technology

The application provides a lamp, which comprises a base plate, a main light source assembly arranged on the base plate, and a side frame extending upwards around the base plate, wherein one end of the side frame away from the base plate is a light outlet, and the light outlet is provided with a light-transmitting film, and the base plate, the side frame and the light-transmitting film form a light mixing cavity. The lamp uses the light-transmitting film to replace the traditional diffusion plate or transparent plate, and has the advantages of low material cost, low transportation cost and warehouse storage space, no need of professional cutting equipment, small density and light volume of the film material itself. Overall, the light-transmitting film is more convenient to use in the whole lamp assembly, and the structure is simpler, so that the weight and cost of the lamp can be greatly reduced. Especially for the large-volume lamp, the application effect is more obvious.

The utility model discloses a square pressure ceramic capacitor core, include: square ceramic base, square ceramic diaphragm, its rim four -around through glass sealant with square ceramic base bottom sintering seal fixed, form sealed cavity, upper printing electrode and lower printing electrode are printed on the opposite surface of square ceramic diaphragm and square ceramic base respectively and are located in sealed cavity, form the two poles of electric capacity, constitute variable capacitance structure, pin, pass through the through -hole of square ceramic base, and are connected with lower printing electrode electricity through conductive silver glue, the square pressure ceramic capacitor core of the utility model compares as follows with existing circular ceramic capacitor core, under the premise of guaranteeing precision and stability, the volume weight is smaller, and the application field is wider, and the processing is simpler, and the loss is lower, and the weight and the volume are smaller, and the lightweight design is more superior, and the economic benefit is higher.
