Abstract

The present invention provides an improved structure of a straight tube type cold cathode fluorescent lamp head which not only greatly reduces the lighting effect but also solves the drawback of greatly reducing the service life of the lamp tube.
An unspecified openwork is formed at an unspecified position on the lamp shell of the lamp tube 1 and an annular surface and an end surface of the lamp head 50, and an unspecified shape is formed. Openwork that allows air to pass through is formed in both the vertical and horizontal directions, and the openwork at different positions in the vertical and horizontal directions allows the gas in the space in the lamp tube to have the best convection pattern. The heat generated when the lamp is lit is effectively discharged to the outside of the lamp tube, and low-temperature air outside the lamp tube can enter the lamp tube, and the heat in the lamp tube is kept at a desirable low temperature. The As a result, the wear of the lamp tube is reduced to a minimum level, and further, the lighting efficiency and service life of the lamp tube are improved, and the problem that the electronic elements in the lamp tube are damaged at a high temperature is solved. Significantly improve the practicality of cold cathode fluorescent lamps.

Description

  The present invention relates to an improved configuration of a lighting fixture. In particular, the present invention relates to an improved energy-saving lamp using a cold cathode fluorescent lamp.

  It is necessary to use a general lamp tube according to the lamp seat. As shown in FIGS. 1 and 2, joint seats (3) are provided on both sides of the lamp seat (2). The lamp head (50) on both sides of the lamp tube (1) is provided with terminals (51). When the lamp is to be used, the terminal (51) of the lamp tube (1) is connected to the joint seat (3). It can be inserted and joined to the lamp seat (2) to form an electrical connection and the lamp tube (1) can be lit.

  As shown in FIG. 3, the straight tube type cold cathode fluorescent lamp referred to in the present invention generally has a hollow tubular shape, and the holding tanks (11) are respectively provided on both sides of the center of the inside. A provided light bulb (10), a flat base (20) that can be inserted into and joined to the holding tank (11), and a plurality of cold cathode fluorescent lamps provided at the bottom of the base (20) A lamp (30), an electronic element (40) provided on the top of the base (20) and connected to the cold cathode fluorescent lamp (30), and a front and rear ends of the lamp shell (10), respectively. A light head (50) having a terminal (51) fixed thereto is provided, and each terminal (51) is connected to the electronic element (40) by a conductive wire.

  Heat is generated after the lamp tube is lit, but since the lamp shell covers the lamp tube in a sealed manner, the heat generated by the lamp tube cannot be discharged and is constantly accumulated in the lamp shell, and as time passes, The temperature is always very high, and this high temperature increases the consumption of the lamp tube, not only reduces the lighting efficiency of the lamp tube, but also greatly reduces the service life of the lamp tube, and the accumulated high temperature Is not ideal because it easily burns and destroys the electronic elements in the lamp tube, causing light bulb damage and greatly reducing the utility of energy-saving light bulbs.

  The one shown in FIG. 4 was previously filed by the applicant of the present invention, and the technical feature of the cold cathode fluorescent lamp is that the lamp shell (10) is basically a watermark whose shape is not specified. The engraving (101) is formed, and the watermark engraving (101) at different positions causes the heat generated when the lamp tube (1) is lit to be discharged outside the lamp shell (10), and the lamp tube (1) Solve overheating problems. However, the applicant of the present invention notices that the lamp tube (1) still cannot achieve the best heat dissipation and cooling effect according to the above-described configuration. 40) is generally provided at the front and rear ends of the lamp shell (10) at positions close to the lamp head (50), so that heat generated from the electronic element (40) is accumulated and discharged to the lamp head (50). I found it difficult. For this reason, the inventor of the present invention has researched and improved this problem again, and has eagerly sought that the straight tube type cold cathode fluorescent lamp has the best heat dissipation effect.

  The present invention has been made in view of the above circumstances. In short, the straight tube type cold cathode fluorescent lamp is affected by the high temperature accumulated in the lamp tube for a long time, and the wear of the lamp tube increases. It is an object of the present invention to provide a straight tube type cold cathode fluorescent light that not only greatly reduces the lighting effect but also solves the drawback of greatly reducing the service life of the lamp tube.

  The technical feature of the improved configuration of the present invention is that the ring face and the end face of the lamp head are formed with a watermark that is not specified in some shape, and air is present in both the vertical and horizontal directions of the entire lamp tube. The openwork leading to it is formed to improve the effect of convection and to provide the best heat dissipation effect for the straight tube type cold cathode fluorescent lamp.

  Hereinafter, the present invention will be described in detail with reference to the drawings. As shown in FIGS. 5 and 6, the structure of the lamp tube (1), which is an improved structure of the straight tube type cold cathode fluorescent lamp of the present invention, is basically the lamp shell (10), the base (20), It consisted of members, such as a cold cathode fluorescent lamp (30), a power distribution element (40), and a light head (50). The lamp shell (10) is a hollow tube having a very good light transmission, and an unspecified shape is formed at an unspecified position on the lamp shell (10). A strip-shaped holding tank (11) is provided on each of both sides of the center of the lamp, and the base (20) has a flat plate shape and is inserted and installed in the holding tank (11) of the lamp shell (10). . A plurality of the cold cathode fluorescent lamps (30) are provided at the bottom of the base (20), and the power distribution element (40) is provided at the top of the base (20) and led to the cold cathode fluorescent lamp (30). The lamp head (50) is attached to the front and rear ends of the lamp shell (10) and fixedly connected thereto, has a terminal (51), and is connected to the power distribution element (40) by a conductive wire.

  The improved configuration of the present invention is that an openwork (501) having a somewhat unspecified shape is formed on the ring face and end face of the lighthead (50). As a result, both the vertical direction and the horizontal direction of the entire lamp tube (1) are formed with an openwork that allows air to pass through. The openwork (101), (501) at different positions in the vertical direction and the horizontal direction allows The gas in the space in the lamp tube (1) becomes the best convection pattern, and heat generated when the lamp tube (1) is lit is effectively discharged to the outside of the lamp tube (1), and the lamp tube (1 ) External cold air can enter the lamp tube (1), and the heat in the lamp tube (1) is kept at a preferred low temperature. As a result, the wear of the lamp tube (1) is reduced to a minimum level, and further, the lighting efficiency and service life of the lamp tube (1) are improved, and the electronic element (40) in the lamp tube (1) is heated at a high temperature. The problem of being damaged can be solved, and the practicality of the straight tube type cold cathode fluorescent lamp can be greatly improved.
