Abstract
An energy-saving lamp brightness control circuit comprises an energy-saving lamp, an energy-saving lam starting/operating circuit connected with the energy-saving lamp, a light modulation circuit connected in the energy-saving lam starting/operating circuit and capable of controlling the brightness of the energy-saving lamp by changing the value of inductive resistance of the circuits. With simple configuration, the utility model can control the brightness of the energy-saving lamp by changing the value of current flowing through the energy-saving lamp upon the change in inductive resistance provided to the loop of the energy-saving lamp. Additionally, several inductances different in inductive resistance are arranged to widen the range of brightness control, provide steady illumination, and save energy.
Description
Technical field
The utility model relates to a kind of energy-saving lamp circuit, the specifically a kind of circuit that can regulate electricity-saving lamp brightness.
Background technology
Energy-conservation owing to have the light efficiency height, energy-saving effect is obvious, and the life-span is long, and volume is little, advantage such as easy to use, more and more be subjected to liking of people, general electricity-saving lamp major part can not light modulation, so can only realize out and close with common switch, this is when wanting to use an electricity-saving lamp to realize different purposes, as illumination, noctilucence indication, reading writing, cause very big inconvenience, can't satisfy the needs of people's life.And traditional incandescent lamp is well accomplished brightness regulation, thereby has limited promoting the use of of electricity-saving lamp.In order to realize to the electricity-saving lamp brightness regulation, China ZL92207225.6 patent name discloses a solution for " fluorescent lamp stepless dimming ballast ", it is that be connected in series a magnetic core again at ballast higher-order of oscillation output choke place can be that inductance value can be made the continually varying coil do relative displacement with coil, by the regulating winding inductance value, change and flow through the lamp current size, play the light modulation purpose, in the loop of circuit, increased regulating winding, realize continuous light tuning, but its structure is relatively complicated, and cost is higher.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, the circuit that can regulate electricity-saving lamp brightness.
According to the above-mentioned purpose requirement, the utility model is realized by the following technical solutions:
A kind of electricity-saving lamp brightness regulating circuit comprises power saving fluorescent lamps, and the electricity-saving lamp that connects with electricity-saving lamp startup and operating circuit, also is connected with one by changing the light adjusting circuit of induction reactance value realization electricity-saving lamp brightness regulation in the circuit in electricity-saving lamp startup and operating circuit.
Described light adjusting circuit is the inductance light adjusting circuit, comprises that some mutual parallel connections and induction reactance value are presented to set up the inductance of putting.
The driving switch that is used for respectively above-mentioned each inductance being sealed in circuit of also connecting in the above-mentioned inductance light adjusting circuit.By the adjusting of driving switch, can change the induction reactance value of the inductance that seals in the circuit, thereby realize regulating the purpose of electricity-saving lamp brightness.
The utility model circuit is simple, thereby change the size of current that flows through electricity-saving lamp by changing the induction reactance value that inserts in the electricity-saving lamp loop, can reach the purpose of regulating electricity-saving lamp brightness, regulating effect is obvious, and the inductance of a plurality of different induction reactance values can be installed as required, the brightness regulation scope is big, and luminous stablizing do not glimmered, effectively energy savings.
Description of drawings
Fig. 1 is the utility model embodiment circuit diagram.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing:
Be the utility model one embodiment circuit diagram as shown in Figure 1, external power source at first inserts by a rectification circuit 1, and rectification circuit 1 output connects a high-frequency oscillating circuits 2, and high-frequency oscillating circuits 2 connects with electricity-saving lamp.At high-frequency oscillating circuits 2 a front ends filter capacitor C also in parallel.Be parallel with three induction reactance values on the inductance L in high-frequency oscillating circuits 2 and be the inductance that certain amplitude increases progressively, simultaneously, a driving switch K also connects in the circuit of inductance front end, driving switch K movable contact head end can connect with inductance respectively, the induction reactance value that inserts in the loop is changed, and then change reaches the purpose that changes electricity-saving lamp brightness through the electric current of electricity-saving lamp.
In the inductance of four parallel connections, the inductance of induction reactance value minimum is set to satisfy electricity-saving lamp and starts.
