Description

The present invention relates to a bulb-type fluorescent lamp having a negative ion generator.

Conventionally, there has been a so-called bulb-type fluorescent lamp having a base that generates negative ions. They are also positioned as convenient air purifiers that can be used in universal light bulb lighting fixtures everywhere. Although the lighting circuit as the lamp or the circuit structure of the negative ion generator is not touched, for the purpose of the present invention, the structure around these negative ion generators will be touched. As for the bulb-type fluorescent lamp type, the electrode of the negative ion generator is provided in a protruding shape at the center of the upper surface of the electric circuit case integrated with the base. In order to make the fluorescent tube compact, it is bent into a spiral shape or a U-shape, and both ends of the fluorescent tube are housed in two holes provided on the upper surface of the electric circuit case. Some were bent into a U shape and some were installed. A needle-like discharge needle or a carbon fiber aggregate is used as an electrode that generates negative ions by the emitted electrons, and is exposed from an insulated protrusion. The reason for the exposure is that these negative ion generators do not have a blowing means, and if the electrodes are covered easily, a phenomenon occurs in which the amount of negative ions released becomes extremely small due to electrical neutralization with the cover. . In this way, there is a dangerous thing that a finger touches easily from the outlet, and it is displayed as a handling precaution.

  As described in the prior art, there is a reason why an electrode has to be exposed in order to effectively diffuse negative ions in a bulb-type light emitter having a negative ion generator that does not have a blowing means. However, the problem is that even though these exposed electrodes have a small amount of current, a high voltage of several thousand volts to several tens of thousands of volts is applied. In addition, depending on the situation such as humidity and dirt, there is a possibility that the short circuit may cause adverse effects on other electronic devices, and the adverse effects on the heart pacemaker cannot be ignored. Similar problems are expected even for LED types that will be widely used in the future, although the lighting system is different. It can be said that products such as light bulbs have been handled with a degree of caution from the prediction that they will not be replaced with the power on. However, lighting fixtures are diverse and many are used at hand, so it is not clear what kind of accident will occur. An object of the present invention is to broadly provide a bulb-type light emitter having a negative ion generator having an electrode safety cover that can safely and efficiently emit negative ions in order to solve such problems.

  As an electrode safety cover for solving the problem, there are means for directly covering the electrode with the safety cover, or covering the electrode, the fluorescent tube, and the light emitter with a glove-like cover so as not to touch the electrode. However, any means must be able to realize safe and effective release of negative ions. In terms of safety, it is necessary to set the shape and dimensions of the outlet so that the electrode does not directly touch the electrode when it is inserted using a test finger prescribed in the Electrical Appliance and Material Safety Law. At the same time, it is necessary to devise such that the release of negative ions is not greatly affected. For that purpose, it should be considered how the discharge needle of the electrode emits electrons. It is well known that electrons are more likely to be emitted the higher the voltage under atmospheric pressure conditions and the sharper the tip of the needle tip. Discharge occurs from the tip of the needle toward the counter electrode so that it can be visually recognized by corona discharge using a discharge needle. In the case of an air discharge without an electric counter electrode, it spreads and diffuses in an inverted conical shape from the needle tip, but its electron density is limited, but it is thought that the region near the needle tip and needle tip is high. The inverted conical region may be the electron radiation field. Although the electron radiation field depends on conditions such as voltage and sharpness, it can be considered that the electron radiation field can be regarded as an inverted cone opened from approximately 30 degrees to 60 degrees with the tip at the center. Also, the electron radiation field can be regarded as an approximation of the negative ion radiation field. This is because the emitted electrons immediately bind to gas molecules in the atmosphere and become negative ions. By the way, since the test finger described above has a maximum diameter of 12 mm, the negative ion blowout opening made in the electrode safety cover must naturally have a size smaller than that. That is, the hole diameter of the negative ion outlet of the electrode safety cover is 12 mm or less, the tip of the discharge needle of the electrode does not touch the inserted test finger, and the edge of the negative ion outlet is opened to about 30 degrees. It is desirable to be outside the electron radiation field. This is an effective radiation field with a high electron density. If conditioned in this way, safety and effect can be expected whether only the electrode is covered in a cylindrical shape or a globe shape. Considering the above-mentioned conditions, it is considered that the position of the electrode is optimally 0.5 mm to 5 mm away from the tip of the test finger. This allowable range may be adjusted because it varies depending on the processing degree of the needle tip and the magnitude of the applied voltage. In this way, it is difficult to get an electric shock, and the amount of negative ions released by discharge can be effectively secured. This positional relationship is important, and is related to minimizing the amount of negative ions released from the electrode due to discharge colliding with the electrode safety cover and being electrically neutralized. In general, the resin has positive ions. If the material of the electrode safety cover is a globe type, it is desirable to use a resin molded product or glass that has excellent translucency and has heat resistance, arc resistance, and impact resistance. The cylindrical electrode safety cover material may be the same or ceramic.

  As described above, the light bulb type light emitter having the negative ion generator having the electrode safety cover of the present invention is performed with a test finger in accordance with the Electrical Appliance and Material Safety Law in order to objectively realize safety. In addition, in order to effectively release the negative ions emitted from the electrode, an effective electron emission field is set to obtain an appropriate electrode position.

The best mode for carrying out the invention

  As described in the means for solving the problem, as the electrode safety cover, directly cover the electrode with the safety cover, or cover the electrode and the fluorescent body such as the fluorescent tube with the glove-like cover so as not to touch the electrode. There is a means. In any case, the best mode basically follows the structure and dimensions of a conventional bulb-type fluorescent lamp or the like. In other words, the light bulb type is the best form, and deviating from this will deny universality. In the case of having a glove, it is only necessary to provide a blowout opening having a size that does not allow the test finger to enter the glove head and determine the position of the electrode so that the edge does not touch the effective electron radiation field. Since the maximum diameter of the test finger specified by the Electrical Appliance and Material Safety Law is 12 mm, the outlet should be less than this. Considering the case where the electrode is a discharge needle, the effective electron radiation field is considered to be an inverted conical region having an angle of 30 degrees around the needle tip. It is desirable to set the interval between 0.5 mm and 5 mm. The relationship between the allowable range and the effective electron radiation field is shown in FIGS. The size of the outlet was shown in the range of 11 mm to 7 mm in diameter.
