JP2002300844A - Half reflection type yellow extremely low illuminance incandescent lamp - Google Patents

Abstract

PROBLEM TO BE SOLVED: To develop an electric bulb having two points of illuminance harmless to plant and illuminance having low insect attraction useful as an insect repellent since a yellow electric bulb has illuminance to harm general plants and is not all-purpose although the yellow electric bulb is conventionally used for a part of plants as an insect repellent by utilizing low insect attraction. SOLUTION: This incandescent lamp is provided with an aluminum reflection film between the maximum diameter part and the top part of a glass bulb and with a yellow coating between the maximum diameter part and the bottom. A vibration-proof filament is positioned in the reflection film, the top part is faced to an action part and illuminates the sky at a lower part to give illuminance of the middle of the sky.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION Conventional yellow light bulbs are used as orchards, carnations, and insect repellent lamps for pets.

[0002]

2. Description of the Related Art A conventional yellow light bulb merely coats an incandescent light bulb with a yellow paint over the entire surface. In other incandescent lamps, the main purpose is to be bright, and shapes and colors are considered. In terms of color, it is a color bulb, color reflex, and color beam bulb technology. In the case of using aluminum reflective film, silver lamps, silver balls, reflex lamps, etc. are used only for high illuminance or indirect lighting by combining with equipment.

[0003]

The conventional yellow light bulb is used only for some applications because of uneven light.
As a countermeasure to this, it is conceivable to install a large number of light sources, but it is not preferable to increase the power consumption. In addition, light pollution by a yellow light bulb to a general plant occurs even at a low illuminance of 1 lux. Some plants, such as orchards and carnations, are apparently unaffected by light. Development of a light bulb that has two functions, illuminance that is harmless to general plants and illuminance with low induced insect properties that can be used as insect repellent.

[0004]

When the filament of an incandescent lamp emits heat and emits light, it is not three-dimensionally uniform when it is limited to the filament portion, and the heat emission in the lateral direction of the filament portion is not uniform. Few. The light bulb according to claim 1 of the present invention is provided with an aluminum reflective film between the maximum diameter part and the top part of the glass bulb, and is painted yellow between the maximum diameter part and the bottom part. Since the vibration-resistant filament is located in the reflection film, uniform heat emission can be obtained as compared with the related art. The yellow light bulb has a low inductive insect property of less than 0.1 lux, and the hollow light is obtained by illuminating the sky at the lower part with the top directed to the working surface.

[0005]

Embodiments of the present invention will be described below. (1) Two aluminum reflective films are provided between the maximum diameter portion 1b and the top of the glass bulb, and 5 yellow paint is applied between the 1b and the bottom. 4 Vibration resistant filaments are located in the 2 reflective film and illuminate the sky at the bottom with the top facing the working surface to obtain hollow illuminance. By doing so, it is possible to obtain illuminance that does not cause light pollution to plants while making use of the low-inducing insect properties of yellow light bulbs. This light bulb will be illuminated all night to make use of the low-induction insects.

[0006]

According to the present invention, the use of agricultural chemicals in the agricultural field can be halved. The silver portion of the aluminum reflective film portion can be expected to have some insect repellent effect due to daytime reflected light. The use of this light bulb aims at eco-friendly agriculture.
Other than the agricultural field, as an example of the use of the high and low illuminance of the yellow light bulb, various uses such as illumination of a park and the use of planting management can be considered. It seems that the all-night lighting using this bulb is environmentally friendly from the viewpoint of load leveling of midnight power.
