The energy saving and environment friendly waterproof electromagnetic type of a kind of LED light-controller
Technical field
The utility model relates to a kind of light-controller, especially relates to the energy saving and environment friendly waterproof electromagnetic type of a kind of LED light-controller.
Background technology
The electromagnetic type light-controller forms an internal control circuit by CdS and AC relay basically, thereby causes that by intensity variation the CdS change in resistance forms size of current in the loop, thereby makes relay adhesive or disconnection realize the open and close of controlled lamp.
Using the electromagnetic type light-controller mainly is that it can produce the wider light-controller of the scope of application.Because the restriction of suction, its movable contact reed thickness only has 0.1-0.12mm, its anti-impact ability.This design is that structure fixture and current-carrying spare share, and because relay coil is heavier, because armature is movable, fixed thereon movable contact reed can gross distortion when falling, thereby properties of product are degenerated even can not work.
The structure coil of electromagnetic type light-controller originally is to be completely fixed on the yoke, and the restriction main resistance that armature is outwards moved comes between automated contact reed and the stationary contact, (0.5 meter freely falling body for example is above the ground level) weak movable contact reed can produce distortion through daring not accept when large rushing shaken, thereby changed distance between armature and the iron core, inhaled moving parameter when seriously changing even can not adhesive lose function.
Along with being widely used of LED light fixture, supporting light-controller does not all have water-proof function with it, and perhaps waterproof ability is not strong, is easy to damage owing to leaking light fixture.
