Description

Lighting device with double structure of embossing type heat sink plate of LED lamp and induction lamp

The present invention relates to a lighting device having a dual structure of a light emitting diode lamp and an electrodeless lamp of the projection heat sink structure, and more particularly, by constructing a high-efficiency electrodeless lamp and a light emitting diode (LED) lamp as a single luminaire By controlling the driving, the surface light source and the point light source characteristics of the illumination are complemented to each other, and the light quantity and the luminous flux of the light emitting diode lamp of the projecting heat sink structure and the electrodeless lamp which have a dual structure of the electrodeless lamp are provided. It is about.

In general, an induction lamp is a fluorescent discharge lamp without an external voltage or current application electrode, and has a high efficiency and high color rendering characteristics. Therefore, it is widely applied in the field of facilities where maintenance and repair are difficult.

The driving principle of the electrodeless lamp is that electromotive force is generated according to the principle of Faraday when a magnetic field generated by high frequency flows through a coil installed outside the discharge tube and passes through the discharge tube. The electromotive force accelerates electrons in a discharge tube in which various gases are mixed, and plasma is generated. The ultraviolet rays excite phosphors applied to the inside of the glass tube to emit only comfortable visible light suitable for illumination.

Tubes of electrodeless lamps are currently produced in various shapes such as bulbs, rounds (rings), and squares (squares), and are used in various fields as follows.

-Industrial lighting (factory high ceiling lighting, machine room, electrical room lighting, explosion proof lighting, etc.)

-Various road lights (street lights, security lights, park lights, tunnel lights)

-Private facilities (lights in apartment complexes, underground parking lots, underground entry routes, etc.)

-Religious facilities (such as auditorium lighting in high-rise religious facilities)

-Schools, research facilities (gymnasiums, laboratory lighting, dormitory lighting, research center lighting, etc.)

-Sports facilities (playground lighting, golf course (indoor / outdoor), ski slope lighting, etc.)

-Military units (maintenance windows, border working areas, lighting of various military units)

Such an electrodeless lamp is widely used when newly installed in a new building or when replacing or replacing an existing lamp. However, in order to replace high-capacity lamps such as 500w, 700w, 1Kw, and 2Kw of high-pressure discharge lamps (metal lamps, sodium, mercury lamps, etc.), the capacity and luminous flux are low.

For example, the 250w metal lamp can be replaced with an induction lamp 150w, but the light flux is small and the straightness of light is insufficient due to the characteristics of the surface light source. In addition, if the floor height is very high, there is a risk of installation or replacement, and the life is short, and maintenance costs are high, but a high capacity lamp is usually used.

In this case, it is difficult to replace the electrodeless lamp with a low-capacity electrodeless lamp. This leads to an increase in installation costs, and in many cases, consumers are reluctant to replace or establish a new product, despite the advantages of the long life of the electrodeless lamp and the low maintenance cost.

In addition, outdoor sports facilities (playground lights, tower lights, etc.) have good color rendering properties, which have less glare than other lights, but similarly, the light force (straightness) that can be far from the light beam is weak to install. There are many difficulties.

The table below shows the characteristics and advantages of electrodeless lamps compared to conventional discharge lamps.
