Fig. 2 low pressure ornamental plaque lamp schematic diagram (unit board);

Fig. 3 lighting circuit schematic diagram;

Fig. 4 pierce circuit figure.

Now in conjunction with the accompanying drawings the structure of low pressure ornamental plaque lamp is described in detail:

By Fig. 1, ornamental lamp hole (1) is set in lampshade (5), the horn mouth electrode (2) that fluorescent tube (1) two ends sealing-in pure iron is made, be filled with inert gas (3) and mercury (4) in the fluorescent tube (1), between fluorescent tube (1) and lampshade (5), be equipped with packing (6) (for example glass cement), lampshade (5) has 4 fixing holes (7), can be fixed in above the automobile with screw.

By Fig. 2, board structure and structural similarity shown in Figure 1, just the length of board can be selected arbitrarily.

By Fig. 4, DC12V is connected to diode D ₁Positive pole, D ₁Negative pole connecting resistance R ₁, be connected to chip IC simultaneously ₁8,7 two ends of (model 555), and resistance R ₄With the elementary winding of transformer B, be connected to triode BG later on again ₂Colelctor electrode, resistance R ₁The other end is connected to IC respectively ₁1 end and 2 ends, again with resistance R ₂Join R ₂The other end is connected to IC ₁3 ends and filter capacitor C ₁, IC ₁6 terminating resistor R ₃With triode BG ₁Base stage, resistance R ₄The other end is connecting resistance R respectively ₅And resistance R ₆, R ₅Again with BG ₁Colelctor electrode joins, and meets BG simultaneously again ₂Base stage, BG ₁And BG ₂Emitter stage and resistance R ₆And capacitor C ₂, IC ₁4 ends and filter capacitor C ₁Common in parallel, ground connection meets fuse S again simultaneously, meets power supply E (DC12V) again, capacitor C ₂The other end be connected to IC ₁5 ends, the secondary windings of transformer B is connected to 700V, 20-25kc.

Optical source wavelength the intensity of spectral line is in the measurement of misty rain sky penetration capacity, wavelength is the ruddiness of 632.8nm in worst misty rain sky, penetration capacity is the strongest, the neon filling ornament lamp sends orange-red light, the red 632.8nm line wavelength of radiation, and the atmosphere penetration capacity is the strongest, this shows under misty rain sky visibility poor condition, neon filling ornament lamp display effect the best, the neon ornament lamp can provide the 10Lm/W light efficiency in addition, is higher than 5 times of incandescent lamps.

For license plate, its power supply can directly use storage battery input 12V, 500mA, and transformer is output as 600-700V, frequency 20-25Kc.

Can use the 12V dc source for advertising board, road plaque, unit board, also can use the high pressure neon sign electron transformer, effect is better.

Low pressure ornamental plaque lamp radiation wavelength has the biggest penetration capacity of misty rain, and clear readable range is a 150-200 rice, is used for vehicle license illuminating effect the best.

After electrode (2) lead-in wire picks out, the cover plate of plastic lamp shade (5) is covered, be coated with fluid sealant and make its bonding waterproof, lead-in wire is connected to higher-order of oscillation power supply (8), at last ornament lamp is in the edge of license plate, uses screw lock.

Be used for license plate and can insert storage battery 12V output, relevant with brake lamp, have flashing function, other boards can connect direct current 12V power supply, also can use the high pressure neon sign electron transformer.

Compared with prior art, low-voltage decorative light for board has following advantage:

1, brightness increases 1-2 doubly, and extremely high depending on degree of opinion, definition, readable range is 150-200 rice;

2, lighting tube brightness raises and the straight line rising with input voltage, eliminates brightness and is saddle with the voltage rising Shape descends;

3, aura discharge stability;

4, high frequency oscillation power, it is very reasonable that the high-frequency and high-voltage parameter is selected, the district's brightness of aura discharge positive column Improve, lengthen, have short circuit, open circuit and polarity connection error protection;

5, make simply, cost is low;

But city, 6 decoration night is convenient to people's daily life again, and especially in the misty rain sky, visibility is good, can be the automotive safety operation and gives security.
