Description

Lighting component

The present invention relates to an illuminant, and in particular to an illuminating member in which a core material having a wiring body having a cable-like LED illuminator is sealed with an oxime rubber, and a fluorenone having transparency is formed on the light-emitting surface side of the core material. The surrounding body of the rubber A is formed on the opposite side of the light-emitting surface as an illuminating member which is surrounded by the fluorenone rubber B which is different in physical properties from the fluorenone rubber A. The present invention is characterized in that, in particular, on the opposite side of the illuminant, a heat conductive fluorenone rubber for protecting the heat for emitting the LED light, or a conductive fluorene rubber for preventing static electricity, or suppressing vibration from the outside is used. The fluorenone rubber having anti-vibration performance is effective for heat radiation, static electricity, and vibration countermeasures, and is excellent in weather resistance, so it can be used for lighting members that are applied to outdoor lighting or decoration. Furthermore, the invention relates to a method of manufacturing a related lighting purchase.

In the past, a cable or a tape-like LED wiring body has been proposed for use in lighting for decoration or outdoor use (Patent Documents 1 to 3: Japanese Patent No. 4,259, 584, Japanese Patent No. 3, 596, 480, and JP-A-2004-247281). However, these functions that do not have a protective substrate are limited in the installation environment.

That is, there are restrictions caused by physical factors such as external stress or impact, vibration, etc., restrictions caused by chemical factors such as moisture or rain, detergents, harmful gases, ultraviolet rays, and biological factors such as mold or insect adhesion. In addition, depending on the use environment, labors such as structural structures for protection need to be installed separately.

For the purpose of preventing this extra labor, although a flexible substrate provided with a light-emitting element is covered with a tube made of polyfluorene oxide, which is suitable for a wider environment, what kind of polymerization is used The oxygen is not described in detail (Patent Document 4: Patent No. 3916651).

As described in Patent Document 4, the structure covered by the tube is simple, but a space (gap) is generated between the tube and the illuminator. Therefore, moisture such as water vapor or rainwater may be mixed in, and internal electrical damage may occur. Further, since the optical space repeatedly causes birefringence or reflection, it is not expected from the viewpoint of light transparency or light transmittance, and there is also a problem that fogging occurs due to moisture inside. In addition, the operation of enclosing the illuminant in the tube is difficult, the efficiency is extremely poor, and the productivity is inferior.

Patent Document 4 also discloses that a flexible substrate on which a light-emitting element is disposed is sealed with urethane, but urethane is considered to be easily yellowed and the transmittance is changed, so that it is not an optimum material, and its low-temperature characteristics are also described. It is also not good, and it loses its softness and deteriorates when used in a severe low temperature environment.

Further, in the wiring body including the illuminator module, it is necessary to avoid heat generation due to illuminance or static electricity due to charging, and to avoid internal damage due to external influence due to external vibration.

Even if it is protected by a transparent material that emphasizes transparency, the above problems cannot be solved, so it is difficult to achieve the purpose with a single material. In addition, in order to solve the other problems described above with a single material, it is necessary to impart additional parts to the molded product, and after molding with a single material, there is further provided, for example, a heat dissipating fin, an antistatic material, or an anti-vibration. Setting work such as external installation of the structure. In the case of an anthrone rubber, it is widely used as a material which imparts characteristics such as heat dissipation or electric conduction, but there is a problem in that design or cost is limited when performance is imparted afterwards.

II hardened. The basic hardenable fluorenone rubber composition II contains the above-mentioned (A) component and (B) component, and if necessary, (C) component is added, and it is sufficient to mix the following additives with the following characteristics.

In order to impart thermal conductivity, it is necessary to add a thermally conductive filler.

The heat conductive filler is at least one fine powder selected from the group consisting of a metal, an inorganic oxide, an inorganic nitride, and an inorganic carbide, and imparts heat conductivity to the fluorenone rubber used in the present invention. Specific examples of the metal include silver, copper, iron, nickel, aluminum, and the like.

The amount of the thermally conductive filler to be added is preferably from 50 to 1,600 parts by mass, particularly preferably from 70 to 1,000 parts by mass, per 100 parts by mass of the component (A). The thermal conductivity obtained by the reduction of less than 50 parts by mass becomes very low, and when it exceeds 1,600 parts by mass, it becomes difficult to mix the materials, and the molding processability is deteriorated.

The thermal conductivity of the obtained fluorenone rubber composition is preferably such that the thermal conductivity is 0.5 W/mK or more. When the thermal conductivity is 0.5 W/mK or more, the release of heat due to the light emission of the illuminator device does not cause internal deterioration, and the illumination member becomes long-lived. Since the conductive material is directly disposed in the core material, the heat conductivity is high, and the heat can be efficiently radiated to the outside, so that the internal loss of the illumination member can be prevented from prolonging the life. Preferably, it is 0.7 W/mK or more. Although it is more than 5 W/mK, it is necessary to mix a lot of heat conductive fillers, so that it becomes difficult to mix, and it is easy to cause deterioration of rubber physical properties.

As the metal particles, gold, silver, copper, or an organic powder or an inorganic powder covering these can be used as appropriate. Examples of the metal oxide include conductive zinc oxide and conductive titanium oxide. As the conductive organic compound, a surfactant or an antistatic agent or the like is used, and a polyester compound or the like is suitably used.

The conductive material may be blended with an anthrone rubber in order to reduce the influence of static electricity of the core material of the light-emitting wiring body, and may be an anthrone rubber having a resistivity to the extent of an electrostatic suppression effect. The specific resistance is preferably in the range of 1 × 10 ⁴ to 1 × 10 ¹² Ω ‧ cm, and more preferably in the range of 1 × 10 ⁵ to 1 × 10 ¹⁰ Ω ‧ cm.

The amount of the conductive material to be blended may be adjusted so that the specific resistance is within the above range. It is necessary to adjust with the materials to be matched.

In order to impart vibration suppression (anti-vibration resistance), generally, the value of the loss coefficient Tan δ due to the dynamic viscoelasticity of the cured fluorenone rubber is an index for improving the vibration-proof effect. In the present invention, the frequency at which dynamic viscoelasticity is used is 30 Hz, and the loss coefficient Tan δ at room temperature is 0.2 or more.

To impart performance at the same time, it is preferred to mix and use separate mating materials. The method of blending the fluorenone rubber composition II sealed on the opposite side of the light-emitting side of the core material can be carried out in the same manner as the fluorenone rubber composition I for providing the fluorenone rubber A.

In the method for producing an illuminating member of the present invention, an uncured fluorenone rubber composition II which provides fluorenone rubber B which provides thermal conductivity, electrical conductivity, vibration suppression property, etc., is disposed on the opposite side of the light-emitting surface in the mold, and The core material is adhered to the opposite surface of the light-emitting surface of the core material, and then the uncured fluorenone rubber composition I of the fluorenone rubber A which provides transparency is disposed in close contact with the light-emitting surface side of the core material, and the mold structure is matched. The shape is adjusted so that the core material is integrated with the curable fluorenone rubber compositions I and II, and then hardened.

Fig. 3 is a view showing an example of the production method of the present invention, wherein the sheet of the fluorenone rubber composition (II) 11 which provides the fluorenone rubber B is attached to the opposite side of the light-emitting surface of the core material 1 as described above. In the case of the adhesion, the release film 13 is disposed on the sheet 11, and the upper mold 14a of the molding die is disposed on the upper side thereof, and the crucible rubber A is provided on the circular dome-shaped cavity 14c of the lower mold 14b. The ketone rubber composition (I) 12 is joined together with the upper and lower molds 14a and 14b, and is pressed and heat-cured by the extruder 15 to form an illumination member.

The hardening temperature is preferably in the range of 80 to 250 ° C, and more preferably the curing temperature is 120 to 200 ° C. The hardening time is from 1 to 60 minutes, preferably from 3 to 30 minutes. When the temperature is less than 80 ° C, the hardening becomes insufficient, and if it exceeds 250 ° C, deterioration of the cured product is caused, which is not preferable.
