Description

  The present invention relates to a desk lamp, and more particularly to a desk lamp that uses a light emitting diode as a light emitter and can be easily recovered for disassembly and recycling.

From the beginning of the invention, the light bulbs used Joule heat to incandescent the conductor to emit light, and filaments were used as the conductor. Such incandescent bulbs have been used as light sources for desk lamps. For this reason, the use of incandescent bulbs was considered for various lighting fixtures. The same is true for desk lamps used on the table.

However, in recent years, it has been found that exhaustion of energy leads to a serious situation that promotes global warming, and in each country, energy can be saved and the development of electric appliances that conform to the concept of environmental conservation has been carried out. It was. For this reason, as for lighting fixtures, products that are most conducive to power saving have been developed.

Conventional bulbs consume a lot of electric energy. For this reason, it is going to be replaced by the light-emitting body which can save electricity naturally. Therefore, light emitting diodes are attracting attention as light emitters that are currently considered to be able to save power most. In the light emitting diode, by slightly increasing the input voltage, the light rays are uniformly dispersed, the irradiation surface is expanded, and the heat dissipation effect can be enhanced. Therefore, in the near future, in order to meet the use needs of lighting fixtures, lighting fixtures having a structure with light emitting diodes will inevitably be developed and become lighting fixtures permanently installed in the home or workplace.

The light emitting diode has a small volume. Therefore, it is difficult to switch to a lighting fixture suitable for a light emitting diode, and there is an urgent need to overcome this point.

The electronic circuit to which voltage is supplied by being transformed is packaged with a material such as a light-transmitting plastic material to form a spherical shell, and a conductive terminal is provided at the bottom end of the spherical shell-shaped body, and the outer periphery thereof is screwed. If engraved into the shape of a light bulb, it can be replaced by an incandescent lamp having electrothermal tungsten as the light emitter of a lighting fixture having a conventional light bulb. That is, the light emitting diode can be directly attached without changing the structure of the conventional electric lamp stand.

However, when both the light emitting diode and the transformer circuit are packaged with a light transmissive material, they cannot be disassembled and taken out. Therefore, if one of them breaks down, it is only possible to throw away the whole, and it becomes difficult to disassemble and classify and collect for recycling, resulting in secondary environmental pollution.
