Description
Technical field
The utility model relates to a kind of mini light night, particularly relates to a kind of LED mini light night.
Background technology
The LED mini light night of Xiao Shouing is to light illuminating part with decompression capacitor after the alternating current step-down in the market, has the cost height, volume is big, has limited it and has applied.
Such as Chinese patent 200420072467.9 disclosed a kind of mini light nights, it is that power input is in series with resistance and electric capacity in circuit.Electric capacity can replace with inductance, and then LED and rectification circuit are connected in parallel.The circuit structure of this utility model is fairly simple, and can be applied in the middle of a lot of circuit.But in the practice, this kind circuit is reasonable not enough.And, at its second examples of implementation, be to make LED pipe and general-purpose diode positive and negative and connect, so, only be a LED half period conducting, in addition the half period electric current flow through general-purpose diode can be not luminous, cause luminous efficiency low, be unfavorable for illumination.Comprehensively described, optimize circuit, effective, low-cost and simple in structure LED mini light night certainly will be that good prospect for sales can be arranged.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of simple in structure, cost is low and LED mini light night with superperformance.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of LED mini light night, comprise housing, the plug that is used for housing is fixed in socket on luminous element in the described housing and the housing, described luminous element is at least one LED light-emitting component, it is characterized in that: this at least one LED light-emitting component and current-limiting resistance and a rectifier diode are in series.This circuit is simple and practical, and the stability of circuit is high, and with low cost, is beneficial to and produces and use.
For prevent the LED light-emitting component flicker, described at least one LED light-emitting component be in series with current-limiting resistance and rectifier diode again after a filter capacitor is in parallel.
Preferably, the size of described current-limiting resistance is 5K Ω-20K Ω; The number of described LED light-emitting component is 1-50, and the LED light-emitting component is in series; The number of described LED light-emitting component is 1-10; The number of perhaps described LED light-emitting component is 1-5.
Preferably, described filter capacitor is 47uF-330uF.
As another embodiment of the present utility model, described current-limiting resistance is a plurality of resistance series connection or composes in parallel.
Compared with prior art, advantage of the present utility model is: compared with prior art, advantage of the present utility model is: circuit is simple and practical, the circuit reliability height, respond well, can produce in enormous quantities, with low cost, electric energy convert light energy efficiency height, economic benefit is obvious.

Fig. 1 is a circuit diagram of the present utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
LED mini light night of the present utility model comprises the light-emitting component in housing and the housing, also has the plug that is used for fixing in socket on the housing.Described light-emitting component is the LED light-emitting component, can be LED luminous tube or LED luminescence chip.The illuminating circuit of this LED light-emitting component be with a plurality of LED light-emitting components that are in series be cascaded with current-limiting resistance R and rectifier diode D after filter capacitor C is in parallel, and then two is connected to power supply.In the circuit, these a plurality of LED light-emitting components are LED1, LED2, LED3, LED4, LED5.The number of these a plurality of LED light-emitting components can be 1-10, preferably can be 1-5, and maximum extends to 50, to improve the brightness of whole mini light night.
Current-limiting resistance R can be 5K Ω-20K Ω, can control the size of current by the LED light-emitting component of mini light night, and this current-limiting resistance R also can or compose in parallel for a plurality of resistance series connection.The size of filter capacitor C is 47uF-330uF, and this filter capacitor C is used to prevent the flicker of a plurality of LED light-emitting components, to offer their stable voltage.Entire circuit is arranged on the circuit board, is installed in the housing of mini light night.
The operation principle of this mini light night is, by current-limiting resistance R the electric current in the illuminating circuit is limited in the 3-30 milliampere, through rectifier diode D circuit is carried out rectification then, offer a plurality of LED light-emitting components, be used for the flicker that filter capacitor C that a plurality of LED light-emitting components are in parallel prevents the LED light-emitting component simultaneously, so that being provided, an illumination stablizes the LED mini light night that circuit is simple and with low cost.
