Detailed description of the invention
Referring now to accompanying drawing this utility model more fully described below, illustrated therein is embodiments more of the present utility model.However, it is possible to be embodied in many different forms this utility model and this utility model is not interpreted as being limited to embodiment set forth herein；On the contrary, these embodiments are provided so that the disclosure will be thorough and complete in an illustrative manner, and will fully pass on scope of the present utility model to those skilled in the art.In describing in the whole text, the element that identical reference instruction is identical.
Fig. 1 be a diagram that the schematic diagram of the environment that wherein can apply embodiment presented herein.Luminous power feeding unit 1 is for supplying power through optical fiber 10a-10f to electrical equipment 20.Electrical equipment 20 such as could be for measuring the instrument of the most suitable entity of such as electric current and/or voltage.Electrical equipment 20 includes the transducer for converting light energy into electric energy, and this allows the luminous energy provided through optical fiber 10a-10f to be powered electrical equipment 20.Owing to using optical fiber 10a-10f (optical fiber is non-conductive) to provide the connection between luminous power feeding unit 1 and electrical equipment 20, therefore there is electrical isolation between power feeding unit 1 and electrical equipment 20.This allows electrical equipment 20 and luminous power feeding unit 1 to be arranged at very different voltage level.Such as, electrical equipment 20 can be arranged at the high voltage of the most hundreds of kV, and luminous power feeding unit 1 can be arranged at substantially grounded voltage.
Luminous power feeding unit includes electrical input 2.Electrical input 2 receives and is in AC (alternating current) form or the electrical power of DC (direct current) form.
Luminous power feeding unit farther includes multiple laser diode module 4a-4f.Each laser diode module in laser diode module 4a is connected to electrical input 2.Each laser diode module in laser diode module 4a-4f includes shell and corresponding laser diode 7a-7f.Alternatively, shell is metal shell, and when being thermally connected to other parts of luminous power feeding unit 1, metal shell allows the too much heat generated by laser diode 7a-7f to be transmitted away from diode (led) module 4a-4f.Alternatively, luminous power feeding unit 1 includes being arranged between each laser diode module in electrical input 2 and laser diode module 4a-4f the power inverter 8 provided.Use power inverter that electrical power is provided with the form being suitable for laser diode module 4a-4f.Such as, if providing AC power on electrical input 2, then power inverter 8 includes AC/DC changer.Alternatively, power inverter 8 includes that voltage changer makes the electrical power provided to laser diode module 4a-4f be in suitable level.
Each laser diode module 4a-4f is releasably attached to luminous power feeding unit 1.This provides outstanding maintainability.Sometimes operating laser diode 7a-7f under high temperature and high luminous power, As time goes on, this causes the degeneration of laser diode chip.Use releasable attachment, can be with the minimum downtime of the quick replacement to the laser diode that electrical equipment 20 execution is degenerated.
Therefore, when any one in laser diode 7a-7f lost efficacy or when having degraded to unacceptable level, the laser diode module 4a-4f comprising malfunctioning laser diode is easily removed and new laser diode module is inserted in its position.Alternatively, there is redundancy in power transmission so that can use the laser diode module of residue work that electrical equipment 20 is powered.By this way, the laser diode module of any inefficacy i.e. can be replaced by hot plug while luminous power feeding unit 1 operates, and eliminates the demand of the downtime of electrical equipment 20 caused due to the laser diode lost efficacy.
Although there is illustrated the luminous power feeding unit 1 with 6 laser diode module 4a-4f, but luminous power feeding unit 1 can being provided with any an appropriate number of laser diode module.
Fig. 2 be a diagram that the schematic diagram of the laser diode module 4 of the luminous power feeding unit of the Fig. 1 with latch mechanism 5.Here, it is illustrated that single diode (led) module 4, it can be any one or more in the diode (led) module 4a-4f of Fig. 1.Use latch mechanism 5 laser diode module 4 can be releasably attached to luminous power feeding unit 1.In one embodiment, laser diode module 4 has the form parameter of SFP (SFP) transceiver.
Fig. 3 be a diagram that the schematic diagram of the laser diode module of the luminous power feeding unit of the Fig. 1 with screw.Here, it is illustrated that single diode (led) module 4, it can be any one or more in the diode (led) module 4a-4f of Fig. 1.Use one or more screw 6 laser diode module 4 can be releasably attached to luminous power feeding unit 1.
Above, Primary Reference some embodiments and is described this utility model.But, as readily understood by the skilled person, in the range of this utility model such as limited by appended Patent right requirement, other embodiments in addition to those embodiments being disclosed above are equally possible.
