Abstract

[PROBLEMS] To not only have the same shape and almost the same luminous intensity as a conventional round tube fluorescent lamp, but also consume much less power than a conventional fluorescent lamp, and directly replace a lighting fixture that used a conventional round fluorescent lamp. Provided is a round LED lighting device that can be used and does not require an auxiliary device such as a glow lamp and is extremely easy to handle.
SOLUTION: A large number of three LED bulb groups connected in parallel in a radial direction are arranged in series in a circumferential direction in a round tube having the same size as a conventional round fluorescent lamp and at least a light emitting portion being transparent. A round LED lighting fixture characterized by inserting a light emitting plate arranged to be connected to an LED can be realized and used in place of a conventional round fluorescent lamp, and the amount of electricity can be greatly reduced over a long period of time. .

Description

  The present invention takes advantage of the characteristics of LED bulbs, which consume much less power and have a longer life than conventional round fluorescent lamps, and has the same brightness as conventional round fluorescent lamps. It is related with the round type LED lighting fixture which can be substituted for.

Currently, round fluorescent lamps are widely used in offices, shops and homes. On the other hand, the LED consumes less power and has a long life, but the illumination is low in luminous intensity and is only used for display boards and traffic lights. It is extremely useful to use this LED as a round luminaire instead of a circular fluorescent lamp.

  The problem to be solved by the present invention is not only having the same shape and almost the same luminous intensity as the conventional round tube fluorescent lamp, but also consumes much less power than the conventional fluorescent lamp, and uses the conventional round fluorescent lamp. It is an object of the present invention to provide a round LED lighting apparatus that can be used as an alternative to the existing lighting apparatus, does not require an auxiliary apparatus such as a glow lamp, and is extremely easy to handle.

  In order to solve the above-mentioned problems, the present inventor has three LED bulbs connected in parallel in a radial direction in a round tube having the same size as a conventional round fluorescent lamp and at least a light emitting portion being transparent. Provided is a round LED lighting apparatus in which a light emitting plate arranged so as to connect a large number of groups in series in a circumferential direction is inserted.

  Since the round LED lighting apparatus according to the present invention has the above-described configuration, it can be used in place of a fluorescent lamp that has been used so far in a lighting apparatus that has conventionally used a round fluorescent lamp. Electricity consumption can be greatly reduced.

  The best mode for carrying out the present invention is shown in the first embodiment.

  In this embodiment, the round tube is divided into a light emitting unit round tube and a power distribution unit round tube, each round tube is divided into a front side and a back side, and only the front side of the light emitting unit round tube is made transparent. In addition, the light emitting plate is divided into three arcs, and one arc-shaped light emitting plate includes 25 rows of 3 LEDs in a row and a total of 75 LEDs. Accordingly, the total number of LEDs used for the three arc-shaped light emitting plates reaches 225. Details of this embodiment are shown in FIGS. In FIG. 2, individual electrical components are omitted, and in FIG. 3, only the back surface of the left arc-shaped light-emitting plate is shown, and the back surfaces of the other arc-shaped light-emitting plates are omitted.

It is explanatory drawing of a surface and a back surface. In these drawings, 1 is a round tube LED lighting fixture, 2 is a light emitting unit round tube, 3 is a power distribution unit round tube, 4 is a light emitting plate, 5 is an LED bulb, 6 is a transparent resin cover, 7 is an opaque bottom, 8 is Printed wiring, 9 LED pin, 10 welded pin, 11 power distribution top cover, 12 power distribution bottom, 13 power distribution board, 14 power distribution board support tube, 15 positioning indicator tube, 16 power input Pin, 17 is the back surface of the light emitting plate, 18 is the back surface of the left 1/3 of the light emitting plate, 19 is the back surface of the central 1/3 of the light emitting plate, 20 is the back surface of the right 1/3 of the light emitting plate, and 21 is the back surface of the light emitting plate 1/3 Connection part, 22 is the upper surface of the upper part of the power distribution part, 23 is the rear surface of the upper part of the power distribution part, 24 is the inside of the bottom part of the power distribution part, 25 is the bottom part of the power distribution part, 26 is the fitting protrusion, 27 is the fitting recess, 28 is the air hole, 29 is the power distribution plate Front side, 30 on the rear side of the distribution board, 31 is a distribution board indicator tube fitting hole, 32 is a capacitor, 33 is a transition , 34 is a coil, 35 is a diode, 36 is a resistor, 37 is a printed wiring, 38 is an LED driver, 39 is an AC input terminal, 40 is an AC input terminal, 41 is a DC output terminal (P), 42 DC main power terminal ( N).

  Since the round LED lighting apparatus according to the present invention has the above-described structure and effect, the conventional round fluorescent lamp is used as it is, and the round fluorescent lamp that has been used so far is used. Since it can be used in place of lamps, the amount of electricity used is greatly reduced, contributing to the development of a new LED lighting fixture industry.
