Description

  The present invention relates to an LED ion bulb having a negative ion generator.

Some bulb-type lighting fixtures were provided with a negative ion generator. For example, there is a light bulb type air cleaning device with an illuminating lamp (Patent Document 1) filed by the present applicant and a light bulb type LED lamp (Patent Document 2) having a negative ion generator.
Japanese Patent No. 4504493 Utility model registration No. 3160961

  These are those that receive electricity from the base and emit negative ions while turning on the illuminating lamp, so that as long as there is a socket, it is possible to obtain an air cleaning effect by negative ions, especially a light bulb type LED having a negative ion generator Since the lamp (Patent Document 2) uses an LED as a light source, it has a low power consumption and has a life of about 40,000 hours.

  Since it has such excellent performance, it has already been commercialized and actually used. However, there were occasional negative ion generation defects with unknown causes.

  As mentioned in the prior art, there were some problems with LED ion bulbs. Even though each part inspection before assembly was normal, there were occasional problems such as malfunctions of unknown cause and negative ion generation failure after assembly, and there was concern about the stability of the product. This is considered to be because the high-voltage lead wire connected from the high-voltage generating part to the discharge needle has an electrical influence on the circuit structure. A strong electric field is generated around the high-voltage lead wire, and if the distance between the circuit components of the circuit assembly and the high-voltage lead wire is closer than expected, there may be dielectric breakdown and other electrical effects. The interior of the housing has a small volume, and the high-voltage lead wire is also bent at the time of manual assembly so that the position is not constant and the interaction between unexpected parts cannot be overlooked. Moreover, the performance defect is affected by the heat of the LED substrate and the high pressure generating part.

  The problem to be solved by the present invention is to widely provide LED ion bulbs having stable quality performance by preventing or reducing the electrical influence caused by the high-voltage lead wires described above.

In order to solve the above-mentioned problem, the present invention relates to claim 1, and a main body case having a base on the base end side and a substantially circular opening on the front end side, and negative ion emission deposited on the front end side of the main body case. A method of manufacturing an LED ion bulb comprising a glove having a hole, wherein a high voltage generating part and a high voltage lead wire are integrally stored in a resin or ceramic capsule having a high dielectric breakdown strength, and the high voltage lead The discharge needle connected by a wire is made into a negative ion generating capsule with a structure protruding from the upper part of the capsule, and this negative ion generating capsule is inserted into a hole provided in the center of the circuit structure composed of the LED element substrate and the LED control circuit substrate, and the circuit configuration into one unit with the body and the negative ion generating capsules, locked to the body by inserting a capsule fixing screw the unit to the main body case By fixing with fixing screws into the fixing screw hole provided on the upper surface of the rib-like structure inside the main body case, also centered easily and accurately fit assembled into the negative ion discharge hole of the glove to the discharge needle It is easy.

  A second aspect of the present invention is the LED ion bulb according to the first aspect, wherein a pair of power receiving plugs installed in the circuit body and a pair of elastic members are also installed in the case body to receive power from the base and the base terminal. The power can be easily received by contact with.

  According to a third aspect of the present invention, in the LED ion light bulb according to the first aspect, a pair of current-carrying members having elasticity for fixing a circuit receives power by contacting the base and the base terminal.

It becomes possible to suppress the heat of the substrate.

  According to a fifth aspect of the present invention, in the LED ion bulb according to the first, second, third, or fourth aspect, a capsule heat dissipation slit is provided on the side surface of the capsule to suppress an increase in the temperature of the high pressure generating portion.

In the present invention, as described above, the high voltage generating portion and the high voltage lead wire are integrally housed in a resin or ceramic capsule having a high dielectric breakdown strength to form a negative ion generating capsule. As a result, the lifetime of the LED ion bulb set can be ensured.

  Since the negative ion generating capsule and the circuit structure are combined into a single unit as claimed in claim 1, the discharge needle can be easily and accurately released by inserting it into the main body case and fixing with a screw or the like. It is aligned with the center of the hole, making assembly easier and reducing costs.

  According to a second aspect of the present invention, the power received from the base and the base terminal can be easily received by the contact between the pair of power receiving plugs in the circuit structure and the pair of elastic power supplies installed in the case body. Therefore, assembly becomes easy.

  According to the third aspect of the present invention, the pair of current-carrying members having elasticity for fixing the circuit can receive power by contact with the base and the contact plate of the base terminal, respectively, and the assembly efficiency is further increased.

  With regard to the fourth aspect, a plurality of air holes are provided on the side surface of the main body case and the circuit board, so that the air can be ventilated with the negative ion discharge holes of the globe, thereby increasing the heat radiation effect.

  According to the fifth aspect, since the capsule heat dissipation slit is provided, the temperature rise can be suppressed.
