Embodiment 1

[0104] made Figure 4 with Figure 5 The lighting fixture 1 shown in , which has the same size and appearance as a general-purpose fluorescent lamp 40 type (length 1198mm). That is, if Figure 4 with Figure 5 As shown, there are 3 rows of LEDs 2 , and 96 LEDs in each row use a total of 288 LEDs 2 . Additionally, if figure 2 As shown, the left end and the right end are provided with pins 21 that can be mounted on general-purpose lighting fixtures for fluorescent lamps, and electrical wiring is performed so as to be compatible with general-purpose lighting fixtures for fluorescent lamps.

[0105]As the LED 2, a white LED manufactured by CREE was used. The first light refractor 3 and the inner tube 5 are manufactured integrally. The thickness d1 of the first light refractor 3 is 4 mm, the width L1 is 5 mm, and the thickness of the inner tube 5 is 1 mm. The angle α is 13°. The number of the first light refracting body 3 is as follows Figure 4 with Figure 5 Shown are ...

Embodiment 2

[0109] made Figure 7-9 The lighting fixture 1 shown in , which has the same size and appearance as a general-purpose fluorescent lamp 40 type (length 1198mm). That is, if Figure 7-9 As shown, the second light refracting body 13 is provided on the outside of the slightly thinner lighting fixture that is substantially the same as that of Example 1, and pins 21 are also provided, and electrical wiring is performed to adapt to the lighting fixture for general-purpose fluorescent lamps. Thus, a lighting fixture is manufactured.

[0110] The second light refractor 13 and the outer tube 15 are manufactured in one body. The thickness d2 of the second light refractor 13 is 2.5 mm, and the width L2 is 2.5 mm. The material of the second light refractor 13 is acrylic resin.

[0111] In this way, a lighting fixture adapted to the general-purpose LED fast start method (FLR) is obtained. Hereinafter, the lighting fixture of this invention which has the said 1st light refraction body 3...

Embodiment 3

[0116] Using the lighting fixture A of the present invention, the illuminance of a place away from the lighting fixture A and the illuminance of a place deviated from the illumination angle directly below the lighting fixture A were compared with commercially available fluorescent lamps and lighting fixture Q.

[0117] Measured Figure 11 The illuminance on the plane P existing at a distance of 1 m from the center M of the tubular lighting fixture 1 obtained in Example 1 in the irradiation direction of light. The illuminance at each of the following points was measured: the point where the angle formed by the straight line L passing through M and extending at right angles from the lighting fixture 1 and the plane P is 45° ( Figure 11 BL and BR); 30° location ( Figure 11 AL and AR); and at the point directly below M, that is, at the point where a line passing through M makes an angle of 90° to that plane P (the foot of the perpendicular from M vertically below the plane P) (...

Abstract

An object is to provide a lighting apparatus in which an LED does not look like a point optical source and which does not provide illumination with drastically reduced light intensity even in a placeaway from the LED and a place angularly deviated from the radiation direction of the LED, and in which a plurality of LED structures are arranged in parallel, utilizing the features of the LED such ashaving no heat, low power consumption, and long life. The problem is solved by use of the lighting apparatus which has an LED group (2) having a plurality of LEDs arranged in parallel and in which anelongated first light reflection member (3) having a cylindrical lens effect is provided on at least the front surface of the LED group. Further, the problem is solved by use of the lighting apparatus in which a plurality of elongated second light reflection members (13) having the cylindrical lens effect are arranged in parallel on at least the front surface of the LED group outside the first light reflection member in such a manner that the second light reflection member is substantially orthogonal to the first light reflection member.

Description

technical field [0001] The present invention relates to a lighting fixture using LEDs, and more specifically, to a lighting fixture in which a light refracting body having a specific structure is provided in front of a plurality of LEDs. Background technique [0002] Many lighting fixtures using LEDs are known (for example, Patent Documents 1 to 4). In addition, there is also known a lighting fixture using LEDs that is interchangeable with fluorescent lamps and whose appearance imitates general-purpose fluorescent lamps. This lighting fixture can be installed in lighting fixtures for general-purpose fluorescent lamps and used as a substitute for general-purpose fluorescent lamps (such as , Non-Patent Documents 1-2). [0003] Compared with fluorescent lamps and incandescent lamps, these lighting fixtures using LEDs have advantages such as no heat generation, low power consumption, and long life, but on the other hand, they also have many problems. For example, there is a pr...
