A lighting lamp with the adjustable size comprises a sucking top disc, a support and a first lighting unit arranged on the support. The lighting lamp is characterized in that a support driving device is arranged in the sucking top disc, after the support extends into the sucking top disc, the support is connected with the driving device, and the support can be stretched in a sliding mode to the outside of the sucking top disc or be contracted to the inside of the sucking top disc in a sliding mode under driving of the driving device. The lighting lamp has the advantages that the support of the lamp can be stretched in a sliding mode to the outside of the sucking top disc or be contracted to the inside of the sucking top disc in a sliding mode under driving of the driving device, the structure is simple; and along with stretching or contracting of the support, the lighting range of the lamp can be changed.

The invention discloses a field operation illuminating device which comprises a base. The upper surface of the base is fixedly connected with two first fixed rods, and the opposite faces of the two first fixed rods are fixedly connected with the left side face and the right side face of a first motor body correspondingly. An output shaft of a first motor is fixedly connected with a driving wheel,and the driving wheel is in transmission connection with a driven wheel through a belt. The inner surface of the driven wheel is sleeved with a first rotary shaft, and the outer surface of the first rotary shaft is sleeved with a first bearing. The first bearing is in clamped connection with the upper surface of the base, and the top end of the first rotary shaft and the lower surface of a movableplate are fixedly connected. The upper surface of the movable plate is fixedly connected with the lower surface of a shell, the upper surface of the movable plate is fixedly connected with the lowersurface of a second motor body through a second fixed rod, and a second motor is located in the shell. According to the field operation illuminating device, an illuminating lamp moves downwards, and therefore the height of the illuminating lamp is adjusted, and then the illuminating range is adjusted.

The invention belongs to the technical field of illuminating lamps and particularly relates to an adjustable illuminating lamp for indoor illumination. The objective of the invention is to solve problems that the illumination range of an existing illuminating lamp mostly unchanged, so the illuminating lamp is not suitable for use in different time periods by people and the illuminating lamp has the single function and is inconvenient to clean. The adjustable illuminating lamp comprises a suspended ceiling, a lamp holder is fixedly mounted at the bottom of the suspended ceiling; a fixed rod isfixedly mounted at the bottom of the lamp holder; a movable plate is slidably connected to the fixed rod, a rotating plate is rotatably connected to the bottom of the movable plate, the rotating plateis in threaded connection with the fixed rod, a cover plate is rotatably connected to the bottom of the rotating plate, a first motor is fixedly installed at the top of the cover plate, a first rotating rod is fixedly installed on an output shaft of the first motor, and the first rotating rod is rotatably connected with the movable plate. The illuminating lamp is easy to operate and convenient touse, the lighting range of the illuminating lamp can be adjusted, meanwhile, the illuminating lamp can be cleaned, the height of the decorative lamp can be adjusted, and people can use the illuminating lamp conveniently.

The invention belongs to the technical field of lighting lamps, in particular to an adjustable lighting lamp for indoor lighting. The illumination range of the lighting lamp is mostly invariable, and it is not suitable for people to use in different time periods, and the function is single and inconvenient to clean. , the following scheme is proposed, which includes a suspended ceiling, the bottom of the suspended ceiling is fixedly installed with a lamp holder, the bottom of the lamp holder is fixedly installed with a fixed rod, the fixed rod is slidably connected to a moving plate, and the bottom of the moving plate is rotatably connected to a rotating plate, The rotating plate is threadedly connected with the fixed rod, and the bottom of the rotating plate is rotatably connected with a cover plate, the top of the cover plate is fixedly mounted with a first motor, the output shaft of the first motor is fixedly mounted with a first rotating rod, and the first rotation The rod is rotatably connected with the moving plate. The invention is simple in operation and convenient in use, can adjust the illumination range of the illuminating lamp, can also clean the illuminating lamp, and can also adjust the height of the decorative lamp, which is convenient for people to use.

A 4G signal transmission signal machine using clean energy belongs to the technical field of urban traffic intelligent control. It is characterized in that it includes a control part, an input part, an emergency part, an auxiliary part and an output part; in an emergency state, the emergency control circuit of the control part can be respectively connected to the signal unit and the camera unit of the control input part, and the motor vehicle control circuit of the output part unit and the non-motor vehicle control unit; the emergency power supply of the emergency part provides electric energy for the operation of each part in the emergency state; the emergency power supply includes a capacitor battery and a piezoelectric charger, and the piezoelectric charger can be connected and supply electric energy to the rechargeable battery. The invention can intelligently regulate traffic facilities, and can use the pressure of the car on the road surface to convert into electric energy, store the above-mentioned clean electric energy and use it to start the emergency traffic control system when the power is cut off, so as to avoid traffic disorder and other situations.

The invention discloses a separated and combined type ceiling lamp which comprises a fixed footstock, and a driving motor is arranged on the lower wall of the fixed footstock. The separated and combined type ceiling lamp is characterized in that the driving motor is connected with one end of a driving mechanism; and the other end of the driving mechanism is connected with a separated lamp. The illuminated area of the ceiling lamp can becomes large or small, and can be randomly changed, the appearance of the lamp can be changed, the illuminated area of the lamp can be randomly changed, the applicability is improved, the structure is simple, and the ceiling lamp is convenient to use.
