The invention belongs to the technical field of cloth spreading equipment, and particularly relates to a width-adjustable cloth spreading table. The width-adjustable cloth spreading table comprises a fixed framework and a movable framework, wherein one side of the movable framework extends into the fixed framework; the fixed framework is connected with the movable framework through a drive mechanism; and under action of the drive mechanism, the movable framework moves in the width direction of the fixed framework to move outwards or shrink inwards to regulate width of the cloth spreading table. The width-adjustable cloth spreading table can freely adjust width within a range of 1600mm-2400mm, is suitable for using requirements of any-width fabric within the range, avoids the problem that a cloth spreading table needs to additionally arrange in the prior art for meeting the using requirements, and ensures that machines of different types can be normally used.

The invention discloses an exhibition cabinet lamp with a rotary lamp cap. The lamp comprises a lamp body and a lamp cap which is rotationally connected to the lamp body, and is characterized in that: the bottom of the lamp cap is provided with an elastic driving component; the elastic driving component comprises a spring seat, a positioning pin, a spring and a pressing plate; the positioning pin is accommodated in the spring seat; the spring seat is provided with an end hole through which the head of the positioning pin extends out; the spring is sleeved outside the positioning pin; one end of the spring is axially limited on the positioning pin; a hole cavity is formed on the pressing plate; the spring seat is fixedly arranged in the hole cavity; the other end of the spring is axially limited in the hole cavity; the pressing plate is fixedly connected with the lamp body; and the spring makes the head of the positioning pin always extend out of the spring seat through an end hole and press against the bottom of the lamp cap. By the lamp, elastic pre-tightening force can be generated at the bottom of the lamp cap, the rotating force of the lamp cap can be adjusted by replacing the spring, and the exhibition cabinet lamp has a simple structure and is convenient to mount. Moreover, the lamp cap can be always pressed against the lamp body under the action of the elastic driving component, and the radiating efficiency is improved.

The invention relates to organic silicon resin encapsulant of large power LED and a preparing method thereof. The encapsulant is prepared by mixing composition A containing vinyl-containing polysiloxane as basic resin, composition B containing vinyl polysiloxane thinning agent, composition C containing hydrogen-containing polysiloxane, platinum catalyst composition D, catalytic inhibitor composition E and tackifier composition F; and the organic silicon resin encapsulant with high refractive index is obtained, and can be used for the encapsulation of various large power LEDs and the potting of other optical purposes. The method solves the problems of the increasing of resin molecular weight and the dissolving preparation of high molecular weight, and the like, by adopting thinning agent method, changes the toughness of resin by adopting cyclosiloxane as cross linker, and improves and maintains the refractive index by adopting refinement method. The method has the advantages that single component package mode and double component package mode can be prepared, the adaptability and the efficiency of encapsulation equipment and processing procedure can be improved, the cost is reduced, and the use is convenient.
