Description

  The present invention relates to an LED lighting fixture that is used as a lighting fixture by replacing a fluorescent lamp of a fluorescent lighting fixture mounted on a ceiling with an LED lighting tube, for example.

  Recently, LEDs with an extremely low power consumption have been developed, and long-life LEDs have been developed. However, use of these LEDs instead of long fluorescent lamps has been accelerated. This LED illuminating tube has a plurality of LEDs arranged and mounted on a flat substrate, and illuminates them by installing them on a long synthetic resin pipe together with the function of emitting the LEDs.

  The LED lighting tube adopting such a structure not only increases the quantity and the cost of using several LEDs to obtain a desired light quantity, but also increases the temperature due to heat generation due to the large number of LEDs. As a result, the luminous efficiency of the LED decreases. Therefore, there is a demand for LED lighting fixtures that are simple in structure, maintain strength, and can be brightened with a small number of LEDs, and how local LED light can be dispersed.

  Patent Document 1 does not consider the above, and the current situation is that no improvement has been made to reduce the LED light emission efficiency when the number of LEDs used is high, and the conventional long fluorescent tube is illuminated with LED. There are many requests from the site to replace the pipe.

Japanese Patent Application Laid-Open No. 2004-133867 does not include a description that takes the above into consideration, and does not disclose it in other things.

  The problem to be solved by the present invention is that the use of a large number of LEDs raises the ambient temperature and decreases the luminous efficiency without increasing the number of LEDs and maintaining the luminous efficiency without increasing the cost. In addition, the LED light can be dispersed, and the structure is simple, and the LED lighting apparatus that can maintain the strength is secured.

  According to the first aspect of the present invention, since the reflector is disposed on the LED base, the light emission of the LED can be reflected by this, so that the inside of the LED lighting tube can be brightened and the local light of the LED light can be dispersed. It is possible to provide an LED lighting apparatus that has an effect.

  In the present invention, it is effective in production to apply a reflector, film, or paint to a place where an LED-based LED is not disposed. As a result, the local light of the LED is dispersed and a soft light distribution can be realized.

  The present invention is sufficiently bright without using many LEDs, is low in cost, and has a simple structure. Moreover, the local thing of LED light can be disperse | distributed and gentle light distribution can be implement | achieved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. FIG. 1 is a cross section taken along the line AA of FIG. Reference numeral 1 denotes an LED board, on which the required number of LEDs 2 are arranged. This LED substrate 1 is inserted and arranged in a shelf 4 of a tube-shaped LED lighting tube main body 3 made of a synthetic resin.

  The shelf 4 is manufactured at the same time as the LED lighting tube main body 3 is manufactured, and maintains a size that can sandwich the LED base 1 from above and below and a strength that can support the LED base 1. In addition, the LED base 1 is located at a position shorter than the diameter of the LED lighting tube main body 3, and is set to a size such that the LED base 1 does not bend to support the weight of the LED 2 and other electronic components. It is.

  On the upper surface of the LED substrate 1 where the LEDs 2 are not disposed, a reflector 5 capable of efficiently reflecting light is disposed. Therefore, the light of the LED 2 of the LED substrate 1 is reflected by the reflecting plate 5 and illuminated forward together with the LED light. In this case, the reflecting plate 5 may be in the form of a film, or may be coated or formed by other means. Reference numeral 6 denotes a terminal, which is a terminal that is inserted into a receiving port of a conventional fluorescent lamp.

  Since the present invention is configured so that the light emitted from the LED 2 is reflected by the reflecting plate 5 on the LED substrate 1, the local light of the LED light is dispersed, and therefore soft light is used for the human eye. . Moreover, it is industrially effective, for example, the cost does not increase.

It is the sectional view on the AA line of FIG. It is a schematic block diagram of a LED illumination tube main body.
