Problems solved by technology
However, electrodeless fluorescent lamps, especially high-power lamps above 100W, generate a lot of heat and cannot be dissipated in time, which will lead to excessively high temperature of the lamp, and decrease in life and luminous efficiency.
Existing electrodeless fluorescent lamps of this kind adopt the scheme of installing heat conducting rods and heat sinks to accelerate heat dissipation, but due to the limitation of heat conduction rate and heat sink volume, the heat dissipation rate is limited, so it cannot be effectively used in high-power products

Embodiment Construction
[0012] Such as Figure 1-Figure 3 As shown, the combined bulb electrodeless fluorescent lamp of the present invention is composed of at least two glass bulb shells 1 connected, wherein grooves are respectively provided on the connecting surfaces of the glass bulb shells 1, and each groove is formed on the glass bulb shell 1. The bulb shells 1 are connected and combined to form a coupling cavity 2, a coupler 3 composed of a heat conducting rod 31, a magnetic core 32 and a coil 33 is inserted in the coupling cavity 2, and the glass bulb shells 1 are connected to each other to maintain a A certain distance, and the distance between each glass bulb shell 1 forms a heat dissipation groove 4 after being connected and combined, and each glass bulb shell 1 is respectively equipped with a main amalgam 5 and an auxiliary amalgam 6 . Because the present invention adopts the combined bubble body electrodeless fluorescent lamp structure in which two or more bubble bodies are partially comb...

The invention relates to a combined bubble body electrodeless fluorescent lamp which is formed by connecting at least two glass bulb shells. Grooves are respectively arranged in the connecting surfaces of the glass bulb shells and form a coupled cavity after the glass bulb shells are connected and combined; a coupler composed of a heat-conducting rod, a magnetic core and a coil is inserted in the coupled cavity; the glass bulb shells are mutually connected at a certain distance; the distance generated between the glass bulb shells forms a heat-radiating groove after the glass bulb shells are connected and combined; and a main amalgam and an auxiliary amalgam are installed in each glass bulb shell. The combined bubble body electrodeless fluorescent lamp has the beneficial effects that with the adoption of the structure of the combined bubble body electrodeless fluorescent lamp combined by two or more bubble bodies, the centers of the bubble bodies are penetrated to form a plurality of heat-radiating channels; the heat generated by the coupler positioned at the center can be quickly transferred out through heat convection; meanwhile, when the surface area of each buddle body self is increased, the heat radiation is also accelerated; particularly, the application effect is better in the high-power electrodeless fluorescent lamp; and compared with a common electrodeless lamp, the combined bubble body electrodeless fluorescent lamp has higher design power, strong function and wider application.
Description
technical field [0001] The invention relates to a lighting device, in particular to a combined bubble body electrodeless fluorescent lamp. Background technique [0002] The bulb-shaped electrodeless fluorescent lamp is a new type of light source with high luminous efficiency and long life. However, electrodeless fluorescent lamps, especially high-power lamps above 100W, generate a large amount of heat and cannot be dissipated in time, which will lead to excessively high temperature of the lamp, and decrease in life and luminous efficiency. The existing electrodeless fluorescent lamp adopts the scheme of installing heat conducting rods and heat sinks to accelerate heat dissipation, but due to the limitation of heat conduction rate and heat sink volume, the heat dissipation rate is limited, so it cannot be effectively used in high-power products. Contents of the invention [0003] The purpose of the present invention is to solve the above existing problems and deficiencies,...
