Abstract
The utility model relates to an LED decorative lamp which belongs to the field of decorative lamps. The LED decorative lamp comprises a power plug and an LED lamp string, wherein the power plug is connected with the input terminal of a bridge rectifier, the output terminal of the bridge rectifier is connected with the LED lamp string 1 after a filter capacitor is connected in parallel, and an EMI filter can be arranged and connected to the input terminal of the bridge rectifier. The LED decorative lamp can provide excellent direct current working environment for an LED chip so as to extend the service life of the LED decorative lamp, ensure the luminous mass and prevent environment pollution such as electromagnetic radiation, electromagnetic interference, etc.
Description
Technical field
The utility model belongs to the decorative lamp field, is specifically related to a kind of LED decorative lamp with rectification, filter.
Background technology
LED is as new and effective solid light source, have advantages such as energy-conservation, environmental protection and long service life, be widely used in the decorative lamp industry, existing LED decorative lamp is that city's net alternating current forms pulse voltage after by bridge rectifier, directly give the statements based on collusion of LED lamp, can cause led chip brightness decay but continue pulse voltage, influence the useful life of LED lamp string.Simultaneously, under this occupation mode,, can cause disturbing pulse and transition generating noise, form environmental pollutions such as electromagnetic radiation, battery interference owing to reasons such as electrical load break-make, capacitor input, the cut-outs of relay class inductive load; Also can cause irregular positive and negative pulse or oscillating impulse, cause that peak voltage, peak current increase severely and damage LED lamp string, potential safety hazard occurs.
The utility model content
The utility model aims to provide a kind of LED decorative lamp that has bridge rectifier and dc pulse voltage filtering setting, to overcome problems of the prior art.
A kind of LED decorative lamp comprises attaching plug, LED lamp string, and attaching plug is connected with the input of bridge rectifier, and the output of bridge rectifier connects with LED lamp polyphone after being arranged in parallel filter capacitor.
Described a kind of LED decorative lamp, the connection of bridge rectifier input is provided with electromagnetic interface filter.
Described a kind of LED decorative lamp, electromagnetic interface filter adopts " π " mode filter.
The protective tube of connecting between the described a kind of LED decorative lamp, the input of bridge rectifier and attaching plug.
A kind of LED decorative lamp, the output end of bridge rectifier is provided with the bayonet joint device.
Above-mentioned LED decorative lamp, novel, rational in infrastructure, have better practicability.Use this LED decorative lamp, can provide good direct current operational environment, thereby prolong the useful life of LED decorative lamp and guarantee luminous mass, also can prevent the generation of environmental pollutions such as electromagnetic radiation, electromagnetic interference for led chip.
