Abstract

The utility model discloses a lamp head of an air convection heat radiation type electrodeless lamp, which comprises a glass case and a center cavity, wherein fluorescent powder is coated on the inner wall of the glass case, the center cavity is formed by the glass case, mercurial is arranged in the inner cavity of the glass case, a power coupler is arranged in the center cavity, the lower part of the glass case is provided with an annular heat radiator, heat radiation fins are arranged on the annular heat radiator, and the lower end of the power coupler is connected with the annular heat radiator. The utility model is characterized in that the side surface of the annular heat radiator is provided with air convection heat radiation holes communicated with the center cavity and the outside. The heat generated by the power coupler arranged in the center cavity can be guided out through the heat conducting rod and can also be guided out in an air convection way through the heat radiation holes. When the lamp head of the electrodeless lamp in the open type structure is used, the temperature of the inner cavity in use is 20 to 50 DEG C lower than that of a sealed type lamp head with the same power, so the heat radiation effect is better.

Description

A kind of cross-ventilation cooling type electrodeless lamp lamp holder
Technical field
The utility model relates to a kind of lamp holder of electrodeless lamp, particularly a kind of lamp holder of electrodeless lamp of cross-ventilation heat radiating type.
Background technology
The bulb inside of electrodeless lamp does not have filament or electrode, have the lamp life-span long, energy-saving effect is remarkable, safe, environmental protection, non-maintaining characteristics, be widely used in places such as factory floor, classroom, library, be specially adapted to high-risk and change the important place of lamp difficulty and maintenance cost costliness.
Electrodeless lamp, in time distributes heat so must install heat abstractor additional on lamp holder because caloric value is big.Existing lamp holder of electrodeless lamp adopts closed design usually, can not circulate in the air and the external world in the lamp holder, and heat distributes by the fin that heat conductive rod passes to lamp shell, and radiating efficiency is low, can't satisfy the heat radiation requirement for powerful bulb.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of radiating effect better lamp holder of electrodeless lamp.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of cross-ventilation cooling type electrodeless lamp lamp holder, comprise that inwall scribbles the glass shell of fluorescent material, the center cavity that glass shell forms, the inner chamber of glass shell is provided with mercurial, be provided with power coupler in the described center cavity, the bottom of glass shell is provided with annular radiator, and annular radiator is provided with radiating fin, the lower end of power coupler is connected with annular radiator, it is characterized in that: described annular radiator side has and is communicated with center cavity and extraneous cross-ventilation louvre.
Mercurial in the described glass shell comprises main mercurial and auxiliary mercurial, and main mercurial is located at the glass shell bottom interior wall, and auxiliary mercurial is located at the glass shell inwall that is positioned at the center cavity middle part.Described annular radiator comprises the heat conductive rod that is installed in the power coupler bottom, is located at the base of heat conductive rod lower end, and the heat dissipating ring that is enclosed within the glass shell lower end, and described heat conductive rod is connected with base, and base is connected with heat dissipating ring.
Further, described radiating fin is arranged on the heat dissipating ring periphery outside, and heat dissipating ring is provided with louvre in the position between each radiating fin.
The beneficial effects of the utility model are: be communicated with center cavity and extraneous cross-ventilation louvre because the annular radiator side of lamp holder of electrodeless lamp has, air in the center cavity can be by louvre and extraneous circulation, the heat that center cavity internal power coupler produces is except deriving by heat conductive rod, can also derive in the cross-ventilation mode by louvre, use the lamp holder of electrodeless lamp of this Open architecture, cavity temperature reduces 20-50 degree centigrade than the closed lamp holder with constant power in during use, and radiating effect is better.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is a cutaway view of the present utility model.
Embodiment
See figures.1.and.2, cross-ventilation cooling type electrodeless lamp lamp holder of the present utility model, comprise that inwall scribbles the glass shell 1 of fluorescent material, the center cavity 2 that glass shell 1 forms, the inner chamber of glass shell 1 is provided with mercurial, is provided with power coupler 3 in the center cavity 2, the bottom of glass shell 1 is provided with annular radiator 4, annular radiator 4 is provided with radiating fin 5, and the lower end of power coupler 3 is connected with annular radiator 4, and annular radiator 4 sides have and are communicated with center cavity 2 and extraneous cross-ventilation louvre 6.
Further, the mercurial in the glass shell 1 comprises main mercurial 7 and auxiliary mercurial 8, and main mercurial 7 is located at glass shell 1 bottom interior wall, and auxiliary mercurial 8 is located at glass shell 1 inwall that is positioned at center cavity 2 middle parts.In case energising assists mercury at first to be evaporated for 8 doses, make bulb luminous when lamp holder at short notice; Behind electrodeless lamp working stability, main mercurial 7 just begins to provide mercury atom.
Annular radiator 4 comprises the heat conductive rod 9 that is installed in power coupler 3 bottoms, is located at the base 10 of heat conductive rod 9 lower ends, and the heat dissipating ring 11 that is enclosed within glass shell 1 lower end, and described heat conductive rod 9 is connected with base 10, and base 10 is connected with heat dissipating ring 11.When electrodeless lamp was worked, the heat that power coupler 3 produces passed to base 10 by heat conductive rod 9, passes to heat dissipating ring 11 by base 10 again, and heat is distributed by the radiating fin on the heat dissipating ring 5.
Further, radiating fin 5 is arranged on the heat dissipating ring 11 periphery outsides, and heat dissipating ring 11 is provided with louvre 6 in the position between each radiating fin 5.Air in the center cavity can be by louvre and extraneous circulation, and the heat that power coupler 3 produces can be derived in cross-ventilated mode by louvre.
Certainly, the utility model is except above-mentioned execution mode, and other equivalent technical solutions also should be within its protection range be.
