No-electrode illumination system

Abstract

In an electrodeless lighting system having a cooling unit for cooling a radiator therein, the electrodeless lighting system includes a microwave generating unit for generating microwave energy; a light emitting unit connected to the microwave generating unit and emitting light by forming plasma by the microwave energy generated in the microwave generating unit; a housing having a first receiving space for receiving the microwave generating unit and sealed-combined with the light emitting unit; a heat exchanger installed at the outer surface of the microwave generating unit to absorb heat generated in the microwave generating unit; a radiator installed at the outer surface of the housing; and a heat transfer member at which one end is connected to the heat exchanger and the other end is connected to the radiator by penetrating the housing to transmit heat from the heat exchanger to the radiator.

Description

technical field [0001] The present invention relates to an electrodeless lighting system, in particular to an electrodeless lighting system provided with cooling means capable of cooling its radiation means. Background technique [0002] Electrodeless lighting systems generate light by using microwave energy to activate a luminescent material filled inside a vacuum bulb to form a plasma. [0003] FIG. 1 is a schematic longitudinal sectional view showing the structure of a conventional electrodeless lighting system. [0004] As shown in Figure 1, the existing electrodeless lighting system includes: a microwave generator 10 installed inside the housing 50 and capable of generating microwave energy; a power supply device 40 that provides power to the microwave generator 10; The device 10 is connected to and transmits the waveguide 20 of microwave energy generated in the microwave generating device 10; the light emitting device 30 can form a plasma region and is activated by th...

Problems solved by technology

[0015] However, in the existing electrodeless lighting system, since the air flows into the housing 50 by operating the cooling fan 60, impurities may enter the housing 50, thereby possibly damaging the internal devices.

In particular, if the electrodeless lighting system is installed externally, raindrops or other foreign matter may enter the housing 50, thereby damaging various components.
