Description

The present invention relates to a structure of a luminaire, and more particularly to a structure of a cold cathode tube luminaire using a cold cathode tube as a light source.

In the current market, cold-cathode tubes that are mass-produced have only a standard size suitable for manufacturing lighting fixtures of 2 and 4 scales, so if they are 1 scale or less (including 1 scale), Alternatively, if there is a demand for special sizes such as 1 to less than 2 or 2 to 3 (including 2), or 3 to less than 4 (including 3) I can't. Therefore, if there is a technology that can accommodate different lighting fixture size designs and custom sizes in various parts of the world, it can provide a wide range of benefits.

Therefore, the present invention solves the problem that tube lighting fixtures that are currently mass-produced universally cannot be adapted to different size designs and custom sizes in various parts of the world due to the extremely sophisticated structure, and the standard size is within 4 scales. An object of the present invention is to provide a structure of a cold-cathode tube luminaire that can improve the practicality of tube-shaped illumination (light source) by enabling smooth production of any cold-cathode tube luminaire.

In order to achieve the above-mentioned object, the cold-cathode tube luminaire of the present invention is provided with a tubular lamp case whose top semicircle does not transmit light (a completely transparent tubular lamp case according to customer demand for luminaires). Alternatively, a dye tube lamp case can be formed). The lamp case is provided with a plate lamp pedestal having electric parts on the top surface and retaining claws on the bottom surface (the plate lamp pedestal is made of a material that can be fixedly supported. ).
Furthermore, a lamp head connected to an electrical component by a cord is fitted to both ends of the lamp case (or only one end of the lamp head may be cord-connected according to the shape of the lighting fixture). The cold cathode tube is locked to the bottom surface of the lamp pedestal by catching claws, and terminals at both ends are connected to electrical components by cords. If the standard lengths of ready-made cold cathode tubes and luminaires are just the right length, they can be assembled as they are. Further, when combined with a special lighting fixture having a different length or shape, an excessively long portion of the cold-cathode tube is bent vertically upward or bent obliquely upward and provided on the top surface of the lamp base.

The present invention having the above-described structure prevents the light generated from the illumination surface of the luminaire from becoming uneven and affects the quality of the illumination, and also produces a luminaire that can flexibly accommodate different lengths and shapes. Aim can be achieved.

It is the perspective view which showed the combination of this invention. It is an exploded view of the present invention. It is an exploded elevation view of the present invention. It is the schematic which showed Example 1 of this invention. It is the schematic which showed Example 2 of this invention.

Example 1
Please refer to FIGS. The structure of the cold-cathode tube luminaire of the present invention includes a lamp case 10, a lamp head 20, a lamp base 30, an electrical component 40, and a cold-cathode tube 50. The lamp case 10 has an opaque tube at the top semicircle (it is possible to make a completely transparent tube lamp case or a dyed tube lamp case according to the customer's demand for lighting equipment. is there). Joint grooves 11 that are the same length as the lamp case 10 are provided at positions on both sides of the central portion in the lamp case 10. The lamp head 20 covers the openings at both front and rear ends of the lamp case 10, and the lamp head 20 is provided with conductive terminals 21. The lamp pedestal 30 has a flat plate shape and is made of a material that can be fixed and supported, and both sides are inserted into the joining grooves 11 of the lamp case 10 and joined. Further, the lamp pedestal 30 is provided with a partition plate 31 at the center of the top surface, and is provided with light guide plates 32 that are the same length as the lamp pedestal 30 near both sides of the bottom surface (no anti-light / light guide plate is provided according to actual demand). May be). A plurality of retaining claws 33 are provided on the bottom surface of the lamp pedestal 30, and chip grooves 301 are provided at the front and rear ends of the lamp pedestal 30. The electrical component 40 is provided on the top surface of the lamp base 30 and is connected to the conductive terminal 21 of the lamp head 20 by a cord. The cold cathode tube 50 is locked to the bottom surface of the lamp pedestal 30 by the retaining claws 33, and the conductive terminals at both ends are connected to the electric component 40 by the cord. A further characteristic point is that one end or both ends of the cold cathode tube 50 having an excessive length are bent vertically upward (or bent obliquely upward), and then the top of the lamp pedestal 30 via the chip groove 301. It is to be bonded on the surface. With the above structure, it is possible to manufacture a cold-cathode tube luminaire that is mass-produced or non-mass-produced and customized to a specific size. In addition, an excessively long portion of the cold cathode tube 50 is bent at the bottom surface of the lamp base 30, and the light beam generated from the irradiation surface of the lighting fixture becomes non-uniform, thereby preventing the problem of affecting the illumination quality.

Please refer to FIG. The cold-cathode tube 50 of the present invention is provided on the top surface of the lamp pedestal 30 so that both ends of the excessively long portion are bent vertically or obliquely upward.

(Example 2)
Please refer to FIG. A stopper plate 34 is provided on one side (or both sides) of the partition plate 31 at the center of the top surface of the lamp pedestal 30 of the present invention to form a larger creepage distance. Accordingly, when the cold cathode tube 50 having a higher wattage is used, the high voltage pulse is prevented from causing an arc discharge in the cord connection portion of the tube-shaped illumination and the electric component 40.
