Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illumination light operating body for a fluorescent lamp, which is covered by a fluorescent lamp, controls light emitted from the fluorescent lamp, and emits the light to the outside.

[0002]

2. Description of the Related Art As is well known, a fluorescent lamp has a glass tube coated with a phosphor, and electrons emitted from an electrode collide with mercury atoms of mercury vapor sealed in the glass tube to generate ultraviolet rays. The light is emitted by converting the ultraviolet light to the visible light when hitting the phosphor. Fluorescent lamps of various luminescent colors such as white, daylight, day white, warm white, bulb color, red, blue, and green have been developed, and are selectively used depending on applications and preferences. The variation of the emission color is realized by changing the type of the phosphor.

In recent years, afterglow fluorescent lamps have been developed that continue to emit light for a certain period of time even when the switch is turned off or a power failure occurs. However, this also requires applying a phosphorescent phosphor to a glass tube. Has been realized.

[0004]

Accordingly, there have conventionally been the following various problems.

[0005] (a) Since it is necessary to change the type of phosphor to change the emission color, there are limits to the types of emission colors that can be realized. (B) Moreover, the color matching and color reproducibility of the phosphor are limited. Therefore, since it is necessary to perform various managements in the manufacturing process, it is difficult to easily obtain various luminescent colors. Therefore, it is not always possible to obtain the optimal type of illumination light for the application. Lighting applications require a small amount of production, which increases the cost. (D) It is possible to change the illumination color by covering the fluorescent lamp with a cover made of a translucent resin. In this case, the cost increases and the space is increased.
(E) Since ultraviolet rays are emitted to the outside, insects may be attracted by the ultraviolet rays and cause burns on products such as products. To prevent this, specially apply an ultraviolet coat or the like. (F) The glass tube may be broken and scattered, which may injure a person or damage an article.
Conventionally, in order to prevent breakage and scattering of such a glass tube, after covering the glass tube with a heat-shrinkable tube, the heat-shrinkable tube is heated and shrunk with hot air or the like, so that the heat-shrinkable tube can be adhered to the glass tube. (G) Even in the case of afterglow fluorescent lamps, special phosphors that emit phosphorescent light are used in glass tubes. Since coating must be performed, the cost is high. (H) In the case where the fluorescent lamp is too bright, dimming is performed using a complicated dimmer or the like, or using a dimming cover made of resin or the like. The present invention has been made in view of such circumstances, which requires dimming, increases costs, and takes up a large space.One object of the present invention is to cover a fluorescent lamp, Incident from fluorescent lamp Irradiating light in a desired wavelength range or removing ultraviolet light without changing the type of phosphor of the fluorescent lamp by changing the spectral distribution of the light emitted and emitting light in a specific wavelength range. It is an object of the present invention to provide an illuminating light operating body for a fluorescent lamp.

Another object of the present invention is to cover the fluorescent lamp and attenuate the light incident from the fluorescent lamp without using a complicated dimmer or using a resin-made light-reducing cover. Another object of the present invention is to provide an illumination light operation body of a fluorescent lamp capable of adjusting the amount of illumination light.

Another object of the present invention is to cover the fluorescent lamp and excite it by light incident from the fluorescent lamp to emit phosphorescent light, thereby turning off the switch or turning off the power and turning off the fluorescent lamp. Another object of the present invention is to provide an illumination light operating body of a fluorescent lamp which keeps illuminating for a certain time.

Another object of the present invention is to provide an illumination light operating body for a fluorescent lamp which can be attached to and detached from the fluorescent lamp, and can be used repeatedly even when the life of the fluorescent lamp has expired, by reattaching it to a new fluorescent lamp.

The inner diameter of the illumination light operating body 1 in the free state may be slightly smaller or larger than the outer diameter of the fluorescent lamp 2. However, when an air layer is generated between the illumination light operating body 1 and the fluorescent lamp 2, light is reflected by surface reflection on the inner peripheral surface of the illumination light operating body 1, which is an interface between the air layer and the illumination light operating body 1. Since the loss occurs, the inner diameter of the illumination light operating body 1 in a free state is made slightly smaller than the outer diameter of the fluorescent lamp 2 and the illumination light operating body 1 is brought into close contact with the fluorescent lamp 2 to improve the light use efficiency. .

The illumination light operating body 1 in a free state
Is slightly smaller than the outer diameter of the fluorescent lamp 2,

Estomer, 1,2-polybutadiene-based thermoplastic elastomer, chlorinated polystyrene-based thermoplastic elastomer, liquid polyisoprene or liquid polybutadiene, or 2 of these substances
Those based on a mixture of two or more substances can be used. In particular, if it is made of silicone rubber, it is excellent in heat resistance, weather resistance and ultraviolet light resistance, so that it can withstand the heat generated from the fluorescent lamp 2 for a long time even when it is in close contact with the fluorescent lamp 2. It can withstand outdoor use for a long period of time and has good workability, so that processing becomes easy.

The tubular illumination light operating body 1 as described above.
For example, a long continuous rubber elastic tube corresponding to the diameter of the fluorescent lamp 2 to be covered is formed by extrusion molding, and the tube can be easily formed by cutting the tube according to the length of the fluorescent lamp 2. it can. However, it goes without saying that the illumination light operating body 1 of the present invention may be produced by a method other than such extrusion molding.

Fluorescent lamp 2 covered with illumination light operating body 1
There are three types: indoor general lighting such as home and office, outdoor lighting, product lighting such as showcases, decorative lighting (illumination), liquid crystal backlight small size, electronic It can be used for any purpose, such as an original for illumination of a copying machine, a facsimile, a scanner, etc., an instrument panel for an automobile, an object for growing plants, and the like. In addition, fluorescent lamp 2

As described in detail below, the rubber elastic body constituting the illuminating light operating body 1 may include a coloring agent, an ultraviolet absorber, a luminous pigment, a fluorescent pigment, and other additives depending on the application. It can be added or changed in thickness,
The type of the base material and the composition of the filler can be changed.

Warm-colored light, such as light from an incandescent light bulb, has the effect of activating the autonomic nervous system. For example, yellow light makes a person feel refreshed and cheerful, while orange light has a physiological effect. It is said that it has the effect of increasing motivation to work actively. It is also said that warm-colored light, such as the light of an incandescent light bulb, also has the effect of making food look delicious. Conversely, the cold-colored light of fluorescent lamps makes food look like it, and slows down the autonomic nervous system, and if it is exposed to the light for a long time, it may become irritated or ill. Is said to have undesirable effects.

However, if a coloring agent such as a yellow or orange-colored pigment or dye is added to the rubber elastic body constituting the illumination light operation body 1, a light conversion layer is formed on the illumination light operation body 1. By changing the spectral distribution of the incident light from the fluorescent lamp 2, the light can be converted into light having a large wavelength region of a warm color system and emitted. This makes it possible to obtain warm-colored illumination light without changing the fluorescent material of the fluorescent lamp 2. Similarly, by adding an appropriate coloring agent or the like, it is also possible to obtain illumination light having various other frequency spectra such as refreshing morning sun light.

Similarly, illumination light of a specific color such as red, blue, green, or yellow is obtained as decoration lighting, showcase lighting, indoor lighting, emergency lighting, lighting of an automobile meter panel, or the like. If desired, a coloring agent such as red, blue, green, or yellow is added to the rubber elastic body constituting the illumination light operation body 1 so that the fluorescent material of the fluorescent lamp 2 can be easily changed. Illumination light of a desired color can be obtained.

In general, the color vision of insects is shifted to the ultraviolet side, that is, the shorter wavelength side, as compared with human color vision.
While you can't feel red, you often feel ultraviolet rays that humans can't see.
Insects tend to collect on fluorescent lamps such as telephone booths and vending machines due to the ultraviolet rays emitted from the lamps. However, if a yellow or red coloring agent or an ultraviolet absorber is added to the rubber elastic body constituting the illumination light operating body 1, the ultraviolet light emitted from the fluorescent lamp 2 can be applied without performing the ultraviolet coating. It can be cut by the illuminating light operating body 1 so as not to go outside and prevent insects from gathering. Also, in fluorescent lamps that illuminate products, etc.,
In the same manner, ultraviolet rays can be cut to prevent burning of the ultraviolet rays of products and the like.

If a phosphor that emits phosphorescence such as a phosphorescent pigment or a fluorescent pigment is added to the rubber elastic body constituting the illuminating light operating body 1, the switch is turned off or a blackout occurs, and Even if the lamp 2 is turned off, the illuminating light operating body 1 emits phosphorescent light for a certain time and keeps shining, so that it can be used as an emergency light for ensuring safety in an emergency or sleeping.

In the case where the fluorescent lamp 2 is too bright, the thickness of the rubber elastic body constituting the illumination light operating body 1, the type of the base material and the blending of the filler are appropriately selected. By appropriately adjusting the light transmittance of the fluorescent lamp 2, the light incident from the fluorescent lamp can be appropriately attenuated and emitted, and the luminous intensity of the fluorescent lamp 2 can be easily adjusted without using a complicated dimmer or the like. it can.

As described above, the illumination light operating body 1 can be prepared by adding an appropriate additive, or by appropriately selecting the thickness of the rubber elastic body, the type of the base material, and the blending of the filler. Although various effects can be obtained, the fluorescent lamp 2 itself can be of a normal type, so that the cost can be reduced. In addition, in this embodiment, since the illumination light operation body 1 has a tubular shape, the illumination light operation body 1 can be repeatedly attached to and detached from the fluorescent lamp 2 by rubber elasticity. Even if it comes, it can be used repeatedly by reattaching it to a new fluorescent lamp 2, so that the cost can be further reduced.

Further, in various situations (particularly, when the fluorescent lamp 2 is used in a passage or a narrow place, or at the time of a disaster such as an earthquake, etc.), the fluorescent lamp 2
