Description

Colour-changing discharging lamp

The utility model is a kind of Variable Luminous Color Discharge Lamps that can controllably send multiple color of light, belongs to the electric light source technology field.

Existing Color-changing lamp belongs to indirect variable color light emitting-type, i.e. the photochromic not time to time change that sends of luminous element, and can be divided into two classes usually: a class is to form Color-changing lamp, for example optical fiber Color-changing lamp, variable color suspension lamp etc. with an illuminating source (incandescent lamp commonly used); Another kind of is to form with sending different photochromic light sources more than three or three, and it utilizes Red Green Blue or three above illuminant colours to mix by different brightness ratios, thereby obtains various photochromic.Existing Color-changing lamp complex structure, cost height, range of application are restricted.

The purpose of this utility model is at the deficiencies in the prior art, provide a kind of operation principle novelty, simple in structure, with low cost, use wide Variable Luminous Color Discharge Lamps.

The utility model utilizes gas discharge to realize that the direct variable color of luminous element is luminous, by the size of electron energy in the control discharge, realize the ionized gas selective excitation, thereby the variable color that obtains gas discharge is luminous.The utility model is made up of fluorescent tube and power supply, controller, translation circuit, output circuit, is characterized in two or more electrodes are housed in the fluorescent tube, and is filled with mist; The function of translation circuit be dc voltage conversion is become have specific waveforms, certain repetition rate and the alternating voltage of certain voltage amplitude, can adopt common emitter push-pull type oscillating circuit.Power supply is connected with translation circuit with controller, and translation circuit is connected with fluorescent tube by output circuit.The shape of fluorescent tube can be designed to straight pipe type, bent tube type or other shape as required; The cross section of fluorescent tube can be done circular or other shape; The electrode of fluorescent tube can be the thermionic emission type, also can be cold cathode.Fluorescent tube vacuumizes and charges into required mist (can comprise certain steam) after shelving, sealing.In order to improve illumination effect, luminescence medium can be assisted employing fluorescent material.

The utility model compared with prior art, have simple in structure, cost is low and advantage such as applied range.It not only can be used for art appreciation, for example makes that family expenses are wall-hanging, pedestal type or suspension type decorative lamp; And can be used as the luminous advertisement of various variable colors; Can also make the variable color signal lamp.

Fig. 1 is the structure block diagram of Variable Luminous Color Discharge Lamps; Fig. 2 is a straight pipe type lamp tube structure schematic diagram; Fig. 3 is the embodiment circuit theory diagrams, the structural representation of the integrated Variable Luminous Color Discharge Lamps of Fig. 4; Fig. 5 is the power control structural representation of separate type Variable Luminous Color Discharge Lamps.

The utility model can adopt scheme shown in the drawings to realize.For example select mercury and neon gaseous mixture as producing the variable color luminescence medium.If when discharge, electron energy was greater than the ionization energy of mercury, and less than the excitation energy of neon, then mercury atom excites and ionization in large quantities, sends the characteristic spectral line (blue light) of reflection mercury; If electron energy is greater than the excitation energy and the ionization energy of neon during discharge, this moment, discharge color depended primarily on the redness of neon.If suitably the size of electron energy in the control discharge just can obtain red luminous to the variable color between the blueness.Fluorescent tube (5) is chosen straight pipe type shown in Figure 2, and its electrode is a thermionic emission type electrode.Power control can adopt circuit shown in Figure 3.Power supply (1) can adopt dry cell power supply, also can adopt single-phase bridge rectification that direct current is provided.Controller (2) can adopt K switch to realize, also can adopt automatic control circuit (for example acoustic control or light-operated etc.) to realize.Translation circuit (3) can adopt common emitter push-pull type oscillating circuit, by triode BG ₁And BG ₂, diode D ₁And D ₂, resistance R ₁, R ₂And R ₃, transformer T ₁And T ₂Constitute.Transformer T ₁The output winding (10-11) that comprises primary coil (1-3), feedback coil (4-5) and formation output circuit (4); Transformer T ₂Comprise primary coil (6-7) and secondary coil (8-9).When K switch was connected, Variable Luminous Color Discharge Lamps was sent ruddiness; When K disconnected, Variable Luminous Color Discharge Lamps was sent blue light.If with resistance R ₃Use variable resistor instead, then can be by changing its resistance, make Variable Luminous Color Discharge Lamps send ruddiness various photochromic between the blue light.Variable Luminous Color Discharge Lamps can be made of one formula or separate type as required, and fluorescent tube and power control are formed a whole, and as shown in Figure 4, can be installed on the wall, also can be assembled into desk lamp type, and its outward appearance and style can be varied.Power control also can be installed separately with fluorescent tube, its structure as shown in Figure 5, as long as a mains switch K ' and a variable color K switch are arranged on the panel, its volume is analogous to the Inductive ballast of 20W fluorescent lamp, but weight is light.
