Description
Technical field
The present invention relates to a kind of improvement of Flameproof intrinsically safe LED illuminating lamp, this illuminating lamp is applicable to down-hole, mine or the use of inflammable and explosive place.
Technical background
In the down-hole, mine or the Flameproof intrinsically safe LED illuminating lamp that uses of inflammable and explosive place, this illuminating lamp is that circuit that possible produce electric spark and device are placed in the explosion-proof chamber, the LED light-emitting component that does not produce electric spark is placed in the essential safety chamber, by the LED light-emitting component power supply of the intrinsicallysafecircuit in the explosion-proof chamber in the essential safety chamber, two chambeies are carried out circuit by the conduit connection post and are connected.Present this illuminating lamp is owing to be subjected to the restriction of essential safety shape parameter to can not do high-power, when output current greater than 0.7 ampere-hour, maximum output voltage can not be greater than 30 volts, be that peak power output can not be greater than 21 watts, because this Flameproof intrinsically safe LED illuminating lamp power output is restricted, therefore can't use in some place.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of power output unrestricted Flameproof intrinsically safe LED illuminating lamp.
The scheme of technical solution problem of the present invention is: the present invention is by current rectifying and wave filtering circuit, mu balanced circuit, and constant-current source circuit, the LED light emitting device group is formed.Power supply input lead and current rectifying and wave filtering circuit, mu balanced circuit, constant-current source circuit is placed on explosion-proof chamber, and the LED light emitting device group is placed on the essential safety chamber; 1 to n constant-current source circuit is arranged in explosion-proof chamber, 1 to n LED light emitting device group is arranged in the essential safety chamber; Each constant-current source circuit output independently of explosion-proof chamber is connected to each LED light emitting device group independently of essential safety chamber by the conduit connection post respectively; Each LED light emitting device group of essential safety chamber is connected in series by the positive and negative order of a plurality of LED light-emitting components.Since each independently the LED light emitting device group respectively by each independently constant-current source circuit power supply, the high-power LED illuminating lamp resolve into by each independently the small-power constant-current source to each independently LED light emitting device group power supply, therefore the operating voltage and the operating current of each LED light emitting device group are little, all satisfy the requirement of essential safe type under operate as normal and malfunction.
Because the utility model has adopted such scheme, can not accomplish powerful problem thereby solved Flameproof intrinsically safe LED illuminating lamp, makes Flameproof intrinsically safe LED illuminating lamp can be applicable to any place.
