To liquid storing bag 32；When lose jam on power when the first dynamic clamping head and quiet clamping head 55 restoring force drive compression zone 52 and piston portion 53 to move up
Return.
Its operation principle is as follows：Modular pressure is arranged in the front of light source module, when pedestrian jams on to modular pressure
When, modular pressure forms pressure output, and it is outer that the liquid (being water in the present embodiment) in pressure-driven catheter 40 flows through heat dissipation
The accommodating cavity 201 of shell 21 to adjustable reflecting module liquid storing bag 32,32 volume expansion of the liquid storing bag drive " V " shape it is reflective
Plate overcomes torsional spring 33 to open to increase the subtended angle of two reflective daughter boards 31, and then increases the beam angle reflected by " V " shape reflector
Degree, to increase the light-emitting angle of LED underground lamp, facilitates road ahead to illuminate；Power is jammed on when modular pressure loses and from extensive
Multiple, accommodating cavity 201 of the liquid through heat-dissipating casing 21 in liquid storing bag 32 is back in catheter 40, and the elasticity of torsional spring 33 is restored
Power drives " V " shape reflector to restore to initial subtended angle.Meanwhile the liquid in catheter 40 flows through the accommodating cavity of heat-dissipating casing 21
201, while heat caused by LED light source 22 is taken away, play the role of helping to radiate, to ensure the service life of the lamps and lanterns.
Further, in the present embodiment, modular pressure uses piston cylinder operator, is directly moved by jamming on power band piston
It is dynamic to carry out triggering driving in turn, it is simple in structure, direct.In other embodiments, other driving structures, such as electricity can also be used
The structure of son control, if modular pressure includes pressure inductor, controller and water pump, pressure inductor is arranged in earth's surface to feel
Power should be jammed on, and exports and is connected to controller, controller is drivingly connected water pump, and to control pump working, the water pump connects water
Between source and catheter 40.When pressure inductor senses pressure, controller is transmitted a signal to, controller controls water pump
It draws water to the liquid storing bag 32 of adjustable reflecting module, increases the subtended angle of " V " shape reflector；The pressure if pressure inductor loses induction
Power, then controller control water pump the water in liquid storing bag 32 is detached.In this way, can equally realize identical effect, only tie
Structure is complex, and needs to use power supply, is not most preferred scheme.
Further, in the present embodiment, the elastic component of the adjustable reflecting module is torsional spring 33, and structure setting is easy.
In other embodiments, elastic component can also be the same tension spring etc. with elastic force, and when using tension spring, tension spring is arranged at " V "
In subtended angle between two reflective daughter boards 31 of shape reflector, both ends are separately connected two reflective daughter boards 31, and liquid storing bag 32 pours liquid
When body, drive two reflective daughter boards 31 that the pulling force of tension spring is overcome to open.
Further, in the present embodiment, the piston shell 51 offers one between the mobile section of piston portion 53 to be run through
Venthole 56 in hollow channel, the piston portion 53 are displaced downwardly to the stage of venthole 56 from initial position, the gas pressed
Body is flowed out from venthole 56 so that can not be pressed to the liquid of catheter 40；The piston portion 53 continues to move down from venthole 56
Stage, air pressure between piston portion 53 and the liquid of catheter 40 increases and then presses to liquid, and then drives liquid flow
It is dynamic.So set, lose jam on power carry out recovery process in, as long as the first dynamic clamping head and quiet clamping head 55 elastic restoring force drive
Piston portion 53 is repositioned at the venthole 56, and catheter 40 is connected to venthole 56, you can is quickly kept in catheter 40
The air pressure at liquid both ends keeps balance, the liquid of liquid storing bag 32 to flow back under the effect of gravity.Also mitigate first simultaneously
The driving dynamics of dynamic clamping head and quiet clamping head 55 increases service life.
Further, in the present embodiment, it is slow that the second elasticity is additionally provided between the adjustable reflecting module and lower housing 11
Structure is rushed, second elastic buffer structure includes：Second guide post (not shown) and third dynamic clamping head and quiet clamping head (not shown),
The second pilot hole (not shown), the adjustable reflection of first end connection of second guide post are offered on the lower housing 11
The connecting shaft of module, second end wear to the second pilot hole and form guide frame, and third dynamic clamping head and quiet clamping head setting is the
Between two pilot hole bottoms and the second end of the second guide post.It can equally play the role of jamming on buffering, prevent under upper cover 12
Shifting is depressed into adjustable reflecting module.
Although specifically showing and describing the present invention in conjunction with preferred embodiment, those skilled in the art should
Understand, is not departing from the spirit and scope of the present invention defined by the appended claims, it in the form and details can be with
