Abstract
The utility model discloses a strobe-free alternating-current fluorescent lamp which belongs to illuminating lamp of daily living equipment. The utility model mainly comprises a chemical lamp. The chemical lamp is connected with a capacitance in series; a circuit composed of the chemical lamp and the capacitance is connected with the chemical lamp in parallel. The strobe-free alternating-current fluorescent lamp provided by the utility model makes alternating current of one group of lights be ahead for 90 DEG comparing to that of another group of lights, owing to adoption of two group of lights connected in parallel and adding capacitance into a supply line; both group of lights illuminates in complement to each other, resolving the stroboscopic problem of the chemical lamps effectively.
Description
Technical field
The utility model relates to a kind of light fixture, particularly a kind of no stroboscopic alternating-current fluorescent lamp.
Background technology
Conventional fluorescent lamps is when connecting alternating current, because the particularity of electrified light emitting, along with the variation of ac frequency, stroboscopic can appear in the light that sends, and is particularly more obvious after length service time, so that human eye usually just can be found.The stroboscopic of light has a strong impact on people's eyesight, and in order to solve the stroboscopic of fluorescent lamp, people have invented three-color fluorescent lamp, but this kind lamp cost height, life-span are shorter, are only applicable to lower powered fluorescent tube.
Summary of the invention
It is low that the purpose of this utility model provides a kind of cost, long service life, the alternating-current fluorescent lamp of no stroboscopic phenomenon.
The purpose of this utility model is achieved in that a kind of no stroboscopic alternating-current fluorescent lamp, comprises fluorescent lamp 1 and fluorescent lamp 2, and fluorescent lamp 1 is connected with electric capacity 3, and the circuit that fluorescent lamp 1 and electric capacity 3 are formed is in parallel with fluorescent lamp 2.
No stroboscopic alternating-current fluorescent lamp provided by the utility model, owing to adopt two groups of lamp parallel connections, the structure that in supply line, adds electric capacity, alternating current by one group of lamp wherein 90 is spent in advance than the alternating current by other one group of lamp, both luminous mutual compensation have solved the stroboscopic problem of fluorescent lamp effectively.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
The utility model adopts following structure: a kind of no stroboscopic alternating-current fluorescent lamp, comprise fluorescent lamp 1 and fluorescent lamp 2, and fluorescent lamp 1 is connected with electric capacity 3, and the circuit that fluorescent lamp 1 and electric capacity 3 are formed is in parallel with fluorescent lamp 2.
This device operation principle is as follows: common alternating-current fluorescent lamp 1,2 is a lighting unit, electric capacity 2 of series connection in the supply line of fluorescent lamp 1, make its alternating current that passes through than preceding more 90 degree of fluorescent lamp 2, when the electric current by fluorescent lamp 2 was in peak value, the electric current by fluorescent lamp 1 was zero.Therefore, in a normal ac cycle, fluorescent lamp 2 is in normal when luminous, fluorescent lamp 1 is in and is lower than normal luminance, otherwise fluorescent lamp 1 is in normal when luminous, fluorescent lamp 2 is in and is lower than normal luminance, two luminous mutual compensation of fluorescent lamp, thus make illuminating ray continuous, can not produce phenomenon frequently.
Claims (1)
1, a kind of no stroboscopic alternating-current fluorescent lamp comprises fluorescent lamp (1) and fluorescent lamp (2), it is characterized in that: fluorescent lamp (1) is connected with electric capacity (3), and the circuit that fluorescent lamp (1) and electric capacity (3) are formed is in parallel with fluorescent lamp (2).
