Abstract
The invention provides a flicker-free illuminating lamp which comprises an electronic ballast and a lampshade. The output end of the electronic ballast outputs parallelly in two circuits, one circuit is directly connected to a first lamp tube, and the other circuit is connected with a phase shifter prior to being connected to a second lamp tube; the phase shifter subjects input current of the input end of the phase shifter to phase shift of pi/2 prior to outputting; the first lamp tube and the second lamp tube are symmetrically arranged in two condensation covers of the lampshade; the condensation covers symmetrically project illumination generated from the first lamp tube and the second lamp tube into a diffusely reflecting plate facing downwards on the lampshade. By the arrangement, lamplight flickering of the illuminating lamp can be basically eliminated on the basis of not changing normal input waveforms of the lamp tubes, and the comfortable lamplight environment can be provided for eyes.
Description
Technical field
The present invention relates to field of illuminating lamps, especially, relate to a kind of illuminating lamp that adopts alternating current to carry out work.
Background technology
At present, electricity-saving lamp is very universal, as various lamp affixed to the ceilings, desk lamp, generally adopts power saving fluorescent lamps.Due to the fluorescent tube characteristic of electricity-saving lamp, generally all need to adopt alternating current to power to fluorescent tube, particularly, as, generally adopt electric ballast, first civil power is carried out to rectifying and wave-filtering, form direct current, then generate high-frequency alternating current by triode oscillating circuit, and then load on fluorescent tube.In view of this kind of reason, fluorescent tube exists flicker problem, and this is for the people of long-time reading study under lamp, and eyes are easily tired, and eyesight is existed to harmful effect; And current solution is, improve the output waveform of electric ballast, to suppress as much as possible flicker, but the input wave form varies of fluorescent tube is excessive, has a strong impact on again its luminescent properties; Therefore, how not changing on the basis of the normal characteristics of luminescence of fluorescent tube, eliminating scintillation, is a problem demanding prompt solution.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of flash-free lamp, this kind of illuminating lamp can normally be inputted on the basis of waveform not changing fluorescent tube, substantially eliminates the scintillation of light, thereby provides comfortable light environment for eyes.
The technical solution adopted for the present invention to solve the technical problems is: this flash-free lamp comprises electric ballast, lampshade; The output of described electric ballast divides two-way parallel output, and wherein a road directly connects the first fluorescent tube, and another road connects the second fluorescent tube after connecting a phase shifter again; Described phase shifter will be exported after the input current phase shift pi/2 of phase shifter input; Described the first fluorescent tube, the second fluorescent tube are symmetricly set in two snoots of described lampshade; The illumination symmetry that described two snoots produce the first fluorescent tube, the second fluorescent tube respectively projects on be located on described lampshade one diffuse reflector down.
As preferably, described lampshade consists of a metallic plate, and this downward flexing in metallic plate both sides forms described snoot; Simple in structure, be convenient to manufacture.
As preferably, described diffuse reflector consists of a shaggy white paster, is directly sticked in the top planes of described lampshade.
As preferably, described electric ballast, phase shifter are arranged in the housing at the described lampshade back side, and this housing is provided with the hoisting mechanism matching with ceiling.
Beneficial effect of the present invention is: this flash-free lamp in use, due to the first fluorescent tube, the second fluorescent tube differs pi/2 phase, therefore, when the first fluorescent tube is dimmed gradually, the second fluorescent tube brightens gradually, when the first fluorescent tube reaches minimum brightness, the second fluorescent tube reaches maximum brightness just, thereby, the total brightness of two fluorescent tubes remains on a comparatively stable value, and due to the first fluorescent tube, the second fluorescent tube carries out indirect illumination to environment after all projecting same diffuse reflector again, therefore, user will can't see the first fluorescent tube and the second fluorescent tube, on visual experience, diffuse reflector directly forms light source, because the brightness on diffuse reflector is the first fluorescent tube, the second fluorescent tube close brightness, therefore very stable, substantially there is no scintillation, can provide comfortable light environment for eyes.
Accompanying drawing explanation
Fig. 1 is the profile schematic diagram of an embodiment of this flash-free lamp.
Fig. 2 is the electrical structure schematic diagram of this flash-free lamp.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1, embodiment illustrated in fig. 2 in, this flash-free lamp comprises electric ballast 41, lampshade 2; The output of described electric ballast 41 divides two-way parallel output, and wherein a road directly connects the first fluorescent tube 11, and another road connects the second fluorescent tube 12 after connecting a phase shifter 42 again; Described phase shifter 42 will be exported after the input current phase shift pi/2 of phase shifter input; Described the first fluorescent tube 11, the second fluorescent tube 12 are symmetricly set in two snoots 21,22 of described lampshade 2; The illumination symmetry that described two snoots produce the first fluorescent tube 11, the second fluorescent tube 12 respectively projects on be located on described lampshade 2 one diffuse reflector 23 down; The illumination projected area of each fluorescent tube, should cover described diffuse reflector 23 completely.
In this embodiment, described lampshade 2 consists of a metallic plate, and this downward flexing in metallic plate both sides forms described snoot 21,22; Simple in structure, be convenient to manufacture.Described diffuse reflector 23 consists of a shaggy white paster, is directly sticked in the top planes of described lampshade 2.
In addition, described electric ballast 41, phase shifter 42 are arranged in the housing 3 at the described lampshade back side, and this housing 3 is provided with the hoisting mechanism matching with ceiling, because this kind of hoisting mechanism is various informative, on each lamp affixed to the ceiling, have, and therefore repeat no more.
Above-mentioned flash-free lamp in use, due to the first fluorescent tube 11, the second fluorescent tube 12 differs pi/2 phase, therefore, when the first fluorescent tube 11 is dimmed gradually, the second fluorescent tube 12 brightens gradually, when the first fluorescent tube 11 reaches minimum brightness, the second fluorescent tube 12 reaches maximum brightness just, thereby, the total brightness of two fluorescent tubes remains on a comparatively stable value, and due to the first fluorescent tube, the second fluorescent tube carries out indirect illumination to environment after all projecting same diffuse reflector 23 again, therefore, user will can't see the first fluorescent tube 11 and the second fluorescent tube 12, on visual experience, diffuse reflector 23 directly forms light source, because the brightness on diffuse reflector is the first fluorescent tube 11, the second fluorescent tube 12 close brightness, therefore very stable, substantially there is no scintillation, can provide comfortable light environment for eyes.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
