Disclosed is a pond culture circulation system based on a bio-toilet module including a culture pond and an annular treatment channel surrounding the culture pond. The annular treatment channel is sequentially provided with a sedimentation zone, a biological purification zone and a water storage zone along a direction of water flow. The culture pond includes a plurality of culture pond units. Each of the plurality of culture pond units is provided with a bio-toilet module in communication with the sedimentation zone through a sewage pipe. The water storage zone communicates with each of the plurality of culture pond units through a gravity-flow culvert. The invention further discloses a use method of the pond culture circulation system based on the bio-toilet module.

Pond culture circulation system based on bio-toilet module

A load driver for driving a load and an LED module are disclosed. In one embodiment, the load driver comprises a converter circuit comprising a controllable switching element configured to be turned on and off and to perform power factor correction for power from a power supply to the load, wherein a control terminal of the controllable switching element is configured for receiving a startup current via the two output terminals, the controllable switching element configured to be turned on by the startup current. The converter circuit further comprises a first inductor, coupled to the power supply at a first end, and to ground at a second end via the controllable switching element, wherein a first one of the output terminals connects to a second end of the first inductor via a diode forwarded from the first inductor, a second one of the output terminals is coupled to the first end of the first inductor.

Driver with open output protection

A luminaire () is disclosed comprising at least one optical chamber () delimited by a light exit window () and a curved reflective surface () extending from the light exit window to a mounting surface () extending from the curved reflective surface towards the light exit window. Each optical chamber comprises a light source () mounted on the mounting surface; and a light guide () extending across part of the optical chamber. The light guide comprises a total internal reflection major surface () facing the light exit window; a further major surface () facing the curved reflective surface, said further major surface comprising a light outcoupling portion () comprising a plurality of light outcoupling structures (); a first edge surface () optically coupled to the light source; and a further edge surface () opposite the first edge surface arranged to direct light towards the curved reflective surface.

Indirect luminaire

Driver with open output protection Starting current for a load driver () for driving a load (L) is provided via the load. In a load driver () for driving a load (L), an operating current or an operating voltage at a reference point is derived from a power voltage bus () by coupling said reference point to said power voltage bus via the load. A load driver () for driving a load (L) comprises an output capacitor () and two output terminals () coupled to the output capacitor. A coupling diode () is coupled in forward connection from one output terminal to a terminal of the output buffer capacitor. A startup terminal () of a converter circuit () is coupled to said one output terminal () to receive a startup current (Is) via the driven load if the load is present to conduct this current.
