Abstract: The present invention provides a high-strength and high-heat-resistant bio-based polyamide composition, which consists of the following parts of materials by mass: 43.50-89.95% of bio-based polyamide resin slices; 10-50% of reinforcements; 0.01-2% of rare earth compounds; 0.01-1% of copper salt antioxidant combinations; 0.01-1% of free-radical scavengers; 0.01-0.5% of heat-conducting masterbatches; 0.01-1% of stabilizers; and 0-1% of dispersants. The advantage of the present invention is presented in that: the bio-based polyamide resin slice is prepared through a stepwise polycondensation process of pentanediamine and adipic acid, or through a stepwise polycondensation process of pentanediamine, adipic acid and terephthalic acid and the pentanediamine is prepared through fermentation of starch, so the prepared polyamide resin pertains to an environmentally-friendly engineering plastic.

Abstract: A lighting apparatus includes a light source, a base plate, a light passing plate and a control module. The base plate has a lateral wall, a bottom plate and a top rim. The lateral wall and the bottom plate form a concave container. The light source is disposed on the bottom plate. A bottom edge of the lateral wall is connected to the bottom plate. A top edge of the lateral wall is connected to the top rim. The light passing plate is attached to the top edge of the lateral wall. a control module. The control module has a sensor and a control circuit. The sensor and the control circuit are placed on two sides of the top rim. The control circuit is connected to the sensor via a through hole of the top rim.

Abstract: A lighting apparatus includes a first set of LED modules, a second set of LED modules, a first lens, a second lens and a driver. The first lens covers the first set of LED modules. The second lens covers the second set of LED modules. The driver supplies a first driving current and a second driving current respectively to the first set of LED module and the second set of LED modules. The driver electively turns on and turns off the first set of LED modules and the second set of LED modules in a first mode and in a second mode. The first light span in the first mode is partially overlapping the second light span in the second mode. The first light span has a smaller span angle than the second light span.

Abstract: The invention discloses an injection made from Chinese herb Ixeris Sonchifolia Hance for treatment of cardio-cerebral vascular diseases and fundus diseases and method of producing thereof. The injection is in a form of lyophilized powder in which the rate of flavone to adenosine is 5 mg:15 ?g or 5 mg:30 ?g. The flavone and adenosine from Ixeris Sonchifolia Hance is more stable in the lyophilized powder form than in liquid form for injection so that it is easy to control the quality of the product so as to make the medicament safe and effective. It has benefit in store.
