Abstract

A lightweight fluorescent lamp in which two FL15 type fluorescent tubes are electrically connected in series and arranged in parallel is optimal for pendant lamps on a personal computer in terms of weight, size, and quantity of light. Although it is difficult to implement. In terms of output, it is equivalent to a 30 watt circular line fluorescent tube, but in terms of energy efficiency, the loss of the incandescent lamp of the input limiting means can be reduced, so it is estimated that it will be nearly 10% better. The problem was that the lighting performance was extremely poor, and when the voltage was low, it was hardly possible to light up.
The present invention has realized the practical application of a "series sequential start lightweight fluorescent lamp" with two FL15 type fluorescent tubes. This particularly new attempt is to replace the fixed resistance of the “ignition-inducing bypass circuit”, which is a circuit unique to “sequential start-up”, with a posistor (substitute single candle light bulb), and the heating current flowing in the filament of the fluorescent tube The time / lighting characteristics have been improved by adding time strength.

Description

Detailed description of the invention

  Consumer lighting

  In the “lightweight fluorescent lamp” of “Japanese Patent Application No. 2004-382676”, a fixed resistance or a small-capacity capacitor is used as the “high electrical resistance”, but since the resistance value is large, the filament of the fluorescent tube passing through this is The heating took time and the time until the fluorescent lamp was turned on was long, and the “immediate lighting” was extremely bad. By simply lowering the resistance value, only the first fluorescent tube, which only needs to be initially ignited (temporary discharge), falls into a semi-lighted state, and the subsequent operation such as the ignition of the second fluorescent tube that should occur subsequently. There was a defect that no longer occurred.

Problems that the device tries to solve

The FL10 type fluorescent tube that has self-ignitability with respect to the power line voltage can be lit at a minimum level even with a fixed resistance, but the steady lighting voltage with two FL15 type fluorescent tubes in series is 100V. Even if it is started sequentially one by one, there is no room to cover the voltage of 1.5 times or more necessary for starting, and application of the serial sequential starting method is difficult and has been forgotten.
On the other hand, if realized, there will be no useless voltage, and even the incandescent lamp of the input limiting means is not unnecessary, but it is thought that it is only necessary to leave a few watts enough to cope with the voltage fluctuation, Energy efficiency can be highest. The FL15 type fluorescent tube is suitable for the housing situation in Japan, both in terms of size and light quantity, and is considered to be the best as a pendant lamp on a personal computer.
1). Search for a method to secure the terminal voltage required for the sequential activation of two FL15 fluorescent tubes.
2). Immediate lighting performance should be at least within the evaluation standard (less than 10 seconds).

Means for solving the problem

Regarding “1.”, there are two possible methods. First, as the characteristics of the discharge tube, generally, if the current is increased, the voltage required for the discharge is decreased, so that the current is increased. However, in order not to overload the fluorescent tube, the increased amount is set as a reactive current and the total current is increased. For this purpose, an AC capacitor having a capacity of about 30 μF is inserted in series with the lighting circuit. The second is that the power supply voltage is converted to pulse direct current by a rectifier circuit using a bridge diode and a direct current capacitor, thereby supplying a load current of 0.3A. About 130V. Secure.
For “2).”, The main cause of the deterioration of the instant lighting performance is the heating time of the filament of the fluorescent tube. This is called a posistor.) By passing a relatively large current at the beginning of energization and heating the filament instantaneously, it becomes high resistance when ignition occurs and the current flowing through the bypass circuit is negligible. The current-carrying characteristics are reduced.
Posista is used for demagnetization circuit of television CRT, etc., and there are various types with different characteristics from several manufacturers, but there is a possibility that the heating time of the filament may be insufficient even if the time rising slope is too steep, The characteristics need to be carefully selected.
In this proposal, two to three commercially available single candlelight-type light bulbs (jujube spheres) that are easy to obtain and function like a posistor were tested in series. The characteristics of the posistor that seems to be suitable for this proposal are “100 ohms or less before energization, 6000 ohms or more when ignition occurs after 2-3 seconds of energization, and at least 3000 ohms or more when lighting is set”. It seems that there is a corresponding product under the trade name “Ceramistor” of company M, but a substitute was used because it was difficult to obtain.
In addition, in order to ensure immediate lighting performance, as shown in “FIG. 2”, a “triple voltage ignition inducing electrode” described in “Japanese Patent Application No. 2004-382676” is provided.

"Figure 1" happens to be a hanging lamp, but it has only 600 grams, so it can be used for a table lamp or any other type of usage.

“FIG. 3” is an electric circuit diagram of an AC serial sequential startup lightweight fluorescent lamp. This method overcomes the shortage of steady lighting voltage by means of increasing current, and as a result, the influence of reactive current in the fluorescent tube, The luminance (light output) of this was inferior to that of the (next) pulse direct current method, but the energy utilization efficiency was recorded as 90%, the highest compared to the conventional method. I / O 30 / 27W. , Power factor -0.99.
On the other hand, the pulse direct current serially activated lightweight fluorescent lamps of “FIG. 1” and “FIG. 2” have sufficient brightness and are not inferior to the latest inverter type fluorescent lamps. I / O 32 / 27W. , Power factor 1.0. If the defect is daringly raised, darkening on the cathode side is likely to occur, it is easily affected by fluctuations in the external voltage, and the immediate lighting performance is also insufficient, but it seems to be improved if an appropriate posistor is used. Both are concise, have few parts, are energy efficient, and are 600 gram lighter than anything, so we believe that they will contribute to resource and energy conservation in Japan in the future.

Effect of device

First, in order to overcome the shortage of voltage, a reactive current is mixed to increase the amount of current if AC remains, and the voltage required for ignition is reduced to a point where it can be achieved, and a rectifier circuit uses 130V. It was confirmed that both the method of supplying power with the pulse direct current and the method of supplying power were effective.
In addition, the “sequential start-up”, the “trigger-inducing electrode” with a triple voltage, and the 1-candle light type light bulb, which is the gist of the present application and considered to have a current-carrying characteristic similar to a posistor, As a comprehensive effect of adopting “high electrical resistance” in the “arc-induced bypass circuit”, even if an FL15 type fluorescent tube without self-ignition is used, the performance of the surface light source wind is the best in comparison with the conventional one. , "Serial sequential startup lightweight fluorescent lamp" was born.
Immediate lighting performance is high in initial energization of a single candle light type small light bulb used as a posistor, so it does not reach the target yet and still takes 15 seconds, but there is a large improvement rate.

It is an external view of the pulse direct current serial starting light weight fluorescent lamp. (I lifted the umbrella.) It is an electrical circuit diagram same as the above. It is an electrical circuit diagram of the AC series sequential startup lightweight fluorescent lamp.
