Description

  The present invention relates to a so-called cold-cathode tube illumination lamp using a cold-cathode tube CCFL (Cold Cathode Fluorescent Lamp) as a light source.

Conventionally, incandescent lamps, fluorescent lamps (fluorescent tubes), and LED lamps are mainly used as lamps for illumination.
In general, both incandescent lamps and fluorescent lamps are very inexpensive in price, and can be stably procured with established technology.
However, incandescent lamps have a short lifespan and require periodic replacement, and are not expected to meet future regulations related to energy saving and CO2 reduction.
Fluorescent lamps are widely used because of their low power consumption and excellent luminous efficiency compared to incandescent bulbs, and have a relatively long lifetime.
On the other hand, the LED lamp can reduce the replacement cost due to its long life, and the effect of energy saving and CO2 reduction is great depending on the usage specification.
However, the introduction cost is high and there are many technical and legal issues such as waste heat problems and final disposal.

Thus, in some fluorescent lamps, the lighting electronic circuit is incorporated in a light bulb type case, and a base similar to that of the light bulb is provided on both sides so that it can be used instead of the light bulb.
In recent years when CO2 emissions have been reduced by reducing power consumption, the usage rate of fluorescent lamps has been increasing year by year.

However, since the fluorescent lamp has a structure of a hot cathode tube (HCFL) type, when the switch is turned ON / OFF, an electric current is supplied to the electrode to rapidly heat and cool the filament coil. Due to the mechanism of releasing electrons and starting discharge, there is a shortened life due to degradation disconnection.
In addition, the conventional straight tube type or ring type fluorescent lamp requires a lighting fixture body equipped with an electronic circuit for lighting the reflecting portion and the fluorescent lamp, and a large space is secured to attach it to the ceiling or the like. Therefore, the layout and design constraints of the illumination target space are increased.

In recent years, a cold cathode tube without a filament coil: CCFL (Cold Cathode Fluorescent Lamp) is used, so that the illumination performance equivalent to that of a general fluorescent lamp is secured, and so-called cold cathode tube illumination is excellent in terms of product life and space saving. A lamp was developed.
This cold-cathode tube illumination lamp emits electrons into a cold-cathode tube without heating from a cathode such as molybdenum, and emits phosphors, and lowers the cathode fall voltage and increases luminous efficiency.
Therefore, the structure of the cold-cathode tube illumination lamp is an elongated linear cold-cathode tube having electrodes such as molybdenum on both side ends and a phosphor or the like arranged inside so that visible light can be irradiated outside the tube, Reflecting plate for reflecting light from the cold cathode tube, electronic circuit unit arranged on the back side of the reflecting plate, elastic member for supporting and feeding terminals on both sides, electronic circuit unit, cold cathode tube, reflecting plate The light-transmitting cylindrical tube is surrounded by a light-transmitting cylindrical tube, and a socket that allows the feeding terminal to be inserted is replaceably mounted in a simple case provided on both sides, eliminating the need for a lighting control circuit. Is.
With this configuration, the illumination lamp is small in size as long as it has a simple and simple case. However, it can easily illuminate with an appropriate high illumination intensity in a small space with a long life.

However, the cold-cathode tube type illumination lamp has a long structure with a long life span because the cold-cathode tube is heavy due to the complicated structure described above, and it is a long-life body. In order to improve profitability, it is restricted to a short body.
Therefore, it is difficult to make the cold cathode tube into a long body from the viewpoint of the ease of maintenance such as mounting and replacement in the simple case, the life and the manufacturing cost.
For this reason, the use of only a cold cathode tube instead of a fluorescent lamp in the case of an existing general fluorescent lamp apparatus has been limited to a case for a short fluorescent lamp.

  The present invention makes it possible to easily arrange short cold-cathode tubes in parallel and in series, and to replace any existing fluorescent lamp device for short fluorescent lamps and long fluorescent lamps with a fluorescent lamp. An object of the present invention is to provide an illumination lamp using an improved cold-cathode tube and an improved cold-cathode tube that can be exchanged and can clearly realize the advantages of the cold-cathode tube.

The present invention satisfies the above-mentioned problems, and features thereof are as follows (1) to (3).

The end closing members 102b on which the connection supporting peripheral surfaces 105 are formed face each other and are arranged in series so that the end closing members 102a fitted with the power supply terminals 101a and 101b can be attached to and detached from the holders 501a and 501b. The cold cathode according to (1) above, wherein the connected supporting peripheral surface 105 of the end closing member 102b in which the connected supporting peripheral surface 105 is formed on the connector 502 is detachably mounted. Tube lighting lamp.

  The cold-cathode tube illumination lamp of the present invention enables easy arrangement of short cold-cathode tubes in series, and of course both for existing short fluorescent lamps and long fluorescent lamps as well as for a new support case. In this case, it was possible to easily replace and replace the fluorescent lamp, and the advantages of the cold cathode tube became obvious. That is, the present invention has an excellent effect that the cold cathode tube illumination lamp can surely obtain an illumination with an appropriate high illumination intensity and can advantageously maintain a long life.
