Embodiment 1

[0059] The lighting fixture of Example 1 of the present invention is shown in Fig. 1(a) and Fig. 1(b). The lighting appliance is an anti-moth lamp for preventing and exterminating night moths, and mainly consists of a light source 1, a ballast 2, a sleeve 3 for protecting the lamp body and ensuring moisture resistance, a hook 4 for hanging the appliance, A wavelength gating color filter 21 is formed.

[0060] As a feature of the present invention, a green fluorescent lamp is used as the light source, and a short-wavelength cut filter is used as the color filter 21 . FIG. 2 shows the spectral radiation characteristic of the green fluorescent lamp, the spectral transmittance of the color filter, and the spectral radiation characteristic after passing through the color filter. Green fluorescent lamps have the largest peak of spectral radiant energy at a wavelength of 525nm, and also have small peaks near 405nm and 435nm. The latter is the characteristic light emitted by the mer...

Embodiment 2

[0062] The difference between the lighting fixture of Embodiment 2 of the present invention and Embodiment 1 is that the light source 1 uses a white fluorescent lamp, and the color filter 21 uses a green color filter. Fig. 5 shows the spectral radiation characteristic of the white fluorescent lamp, the spectral transmittance of the color filter, and the spectral radiation characteristic after passing through the color filter. The spectral radiation characteristic after passing through the color filter has a peak of spectral radiation energy at a wavelength of 545nm, according to Figure 6 , the relative light absorption of phytochrome is 49, according to Figure 7 The anti-moth effective radiation flux is 1101mW, and the ratio of relative plant pigment light absorption to the same amount of anti-moth effective radiation is 0.04. The spectral radiation energy below 460nm is below 10% of the peak value. Thereby, while exerting the moth-proof effect, the influence on flower bud ...

Embodiment 3

[0065] The lighting fixture of Example 3 of the present invention is shown in Fig. 8(a) and Fig. 8(b). The lighting fixture is a floodlight for preventing and exterminating noctuid moths, is installed on poles arranged around farmland, and is suitable for illuminating a wide range.

[0066]In this embodiment, an HID lamp 8 is used as the light source 1 . A lampshade 9 is attached around the HID lamp 8 , and a reflector 10 is formed on the lampshade 9 . The reflector 10 makes it easier to irradiate the light emitted by the HID lamp 8 . In addition, a color filter 21 is provided inside the front glass 20 . In particular, a green HID lamp is used as the light source 1 and a green color filter is used as the color filter 21 . FIG. 9 shows the spectral radiation characteristic of the green HID lamp, the spectral transmittance of the color filter, and the spectral radiation characteristic after passing through the color filter. The spectral radiation characteristic after passing ...

Abstract

This lighting fixture is equipped with a light source (1) having a spectroscopic radiation energy peak between a lower limit 560 nm of 560-700 nm wave length zone having a potent effect on the formation of flower buds of the plant and a lower limit 460 nm of 460-580 nm wave length zone having a high moth-protecting effect and also <=0.05 ratio of a value obtained by integrating a product of a spectroscopic radiation energy [Phi]e([lambda]) and a spectroscopic absorbance Pr([lambda]) of phytochrome in a range of 560-700 nm to radiant flux contained in 460-580 nm wave length zone.

Description

technical field [0001] The present invention relates to a lighting fixture mainly suitable for use as a moth-proof lamp. Background technique [0002] In the past, moth-proof lamps were used in orchards and farmland to prevent and eliminate noctuid moths. Noctuids fly to the orchard at night, pierce the fruit and suck the juice with their mouths. Therefore, the fruit rots around this place, and the commodity value deteriorates. Also, in farmland, the larvae of noctuid moths eat up buds and leaves of vegetables and flowers, reducing the harvest. Noctuid moths, on the other hand, because of their nocturnal nature, are active at night when it is dark all around, and largely inactive during the day when the surrounding is bright. Therefore, the principle of using moth-proof lamps to control noctuid moths is to use moth-proof lamps to illuminate orchards or farmland at night, just like daytime, so that the compound eyes of noctuid moths can adapt to the brightness, thereby inh...
