Description

LIGHT GRID SYSTEM FOR TRANSMITTING LIGHT OF CENTRALIZED LIGHT GENERATION APPARATUS}

The present invention relates to an optical grid system for transmitting light from a centralized light generating device, and more specifically, to generate a large amount of light in one centralized light generator, a large amount of light is transmitted at high power. Optical grid for transmitting light from a centralized light generator that transmits to an individual light diffuser installed in a place (building, etc.) where light is required through a possible light transmission line (eg, optical fiber) It's about the system.

In the field of lighting, LED lighting is replacing traditional lighting sources such as fluorescent lamps and incandescent lamps because of its low price and high brightness of the light source. LED is a light source using light energy generated at the junction of the PN diode, and has the advantages of long life, small size, low power consumption, and fast reaction time.

Until now, in the lighting field, many technologies have been developed, including the development of fluorescent/incandescent/LED light sources, but the lighting method makes light sources and luminaires into one terminal (illumination device) and connects to the power grid to produce light from each terminal. The terminal lighting method used is still in use.

In addition, in the case of LED lighting, even though it is a device with high photoelectric efficiency and low energy loss, only 15% of the energy consumed by the system is converted into light and 85% is wasted as heat.

In order to reduce heat loss, thermoelectric power generation for a single light fixture that recovers waste heat generated by LED elements is being developed in the early stages of technology, but no technology has been developed to change the lighting method.

In addition, the concept of collecting and concentrating light energy and transmitting it to each terminal through a diffuser has not yet been utilized, and the technology of package technology in the form of a silicon plate that connects the LED light fixture with it is not yet utilized. It is just developing.

In the lighting field, fluorescent/incandescent/LED light sources and luminaires are made into a single terminal (lighting device), and the terminal lighting method, which is used individually by producing lights at each terminal by connecting to the power grid, is still used.

Currently, LED lighting that replaces fluorescent lamps has the advantages of long life, small size, low power consumption, and fast reaction time, but the heating problem of LED lighting is seriously caused when LEDs are actually configured and used. .

Although many improvements are being made, in the case of high power LED lighting, heat loss is seriously occurring, and when 1W power is consumed in a 1mm ² area LED lighting, the loss reaches 80%.

The thermal energy generated at the junction of the PN diode sometimes rises to 1000°C. In order to use the system, a cooling element is additionally used because it must be kept below 125°C at all times. Since the heat energy generated very much can affect the light generation wavelength range of the PN diode, control of the generated heat energy has become a very big problem in LED lighting.

The lighting equipment is connected to the power grid and generates light and heat at the end. At this time, even in the case of a highly efficient LED light, only 15% of the energy consumed is converted into light, and 85% is wasted as heat.

When using fluorescent or incandescent lamps, which are less efficient than LEDs, energy loss is more than 85%. There are power (motor) and heat (electric heating, heating and cooling) devices as the way to connect the terminal to the power grid, but they use most of the energy consumed (over 80%) by converting it to desired power and heat.

Only lighting is a system that uses less than 15% with low efficiency, and it takes fire risks due to heat generated, increased cooling burden, reduced deterioration and usage time, required space required for cooling components, and design restrictions.

In addition, since most of the lighting devices are operated based on a small terminal device, there is a problem in that the energy conversion efficiency of electric energy to light energy is low.

In the case of fluids (electricity, water, oil, gas), it is based on a grid system that centralizes production by applying power grids, water grids, and heat grids (local heating). While it is the centralized utility infrastructure that is the basis, lighting is not the only grid method.

 For this reason, there is a need for a new lighting system of a grid type different from the existing one to increase energy efficiency in the use of lighting.
