Abstract
The utility model relates to a high-frequency electrodeless lamp, belonging to the technical field of electronic illumination. The high-frequency electrodeless lamp, which is a novel light source without filaments or electrodes, utilizes a high-frequency electromagnetic field to excite gas to discharge, and finally visible light is generated for illumination. The utility model provides a high-frequency electrodeless lamp, which is composed of a high-frequency magnetic field generator, a discharge bulb and a heat dissipating device. The high-frequency electrodeless lamp has the technical key of the heat dissipating device of compact structure, good heat dispersion and a beautiful shape.
Description
The utility model belongs to the electrical lighting technical field.
HF lamp without electrodes is a kind of new type light source that does not have filament or electrode.Mainly comprise according to Chinese patent 91102205.8 disclosed electrodeless lamps: a vacuum-tight discharging bulb, be filled with metal vaporizer and rare gas in it, inwall scribbles fluorescent material, and a recessed cavity is arranged in the bottom of discharging bulb; A coil that is wound on the sleeve that synthetic material makes is positioned at the cavity of discharging bulb; A tubulose iron core of being made by soft magnetic material is contained in the sleeve of coil coiling; The closed tubular vessel that liquid is housed, one head are in the tubulose iron core that soft magnetic material is made, and stretch out outside the cavity of discharging bulb together with the sleeve of being made by synthetic material its other end, fixedly connected with the heat radiation bearing; A high-frequency electrical component, its output is connected with induction coil.This HF lamp without electrodes, its integral heat sink ability, and be subjected to the influence of extraneous connector heat-sinking capability; The high frequency magnetic field that is produced by electron source and coil is subject to the interference of extraneous electromagnetic field of high frequency in addition, influences the stability of its work.
The purpose of this utility model is to propose a kind of HF lamp without electrodes with practical value.Its compact conformation, perfect heat-dissipating, the life-span is long, is the new type light source of indoor and outdoor lighting.
HF lamp without electrodes of the present utility model comprises: high frequency magnetic field generator, discharge big gun (6) and heat abstractor.Its technical scheme is as follows: the high frequency magnetic field generator is made up of high-frequency electrical component (2) and coil (8), coil winding is on the sleeve pipe that one section synthetic material is made, casing length is longer than loop length slightly, place again on the thermal conductor (5), the high-frequency electrical component places the junction of heat radiation lampshade (9) and heat radiation bearing (10), and high-frequency electrical component and coil are carried out and be electrically connected; Discharging bulb (6) adopts concave structure, is filled with the low pressure mist in the chamber and carries out airtight; Heat abstractor is made up of heat radiation lampshade, heat radiation bearing and thermal conductor, will be fixedlyed connected with thermal conductor and heat radiation bearing in placing the discharging bulb re-entrant cavity by the heat radiation lampshade that metal material is made.
HF lamp without electrodes of the present utility model, because the length of coiling sleeve pipe is shorter, heat exchange area between thermal conductor and the discharging bulb re-entrant cavity is bigger, the efficiently radiates heat area of entire heat dissipation device is obviously big thereby can satisfy the requirement of electrodeless lamp efficiently radiates heat in addition, is not subjected to the influence of extraneous connector heat-sinking capability; Also have the reflection light harvesting effect of common lampshade simultaneously as the heat radiation lampshade of heat abstractor part, promptly lamp and lampshade are integrated; This heat abstractor can also protect high-frequency electrical component or high frequency magnetic field generator to avoid the interference of frequency electromagnetic waves on every side effectively in addition, i.e. shielding action, thus make the work of electrodeless lamp more stable.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of HF lamp without electrodes of the present utility model.(1) is that power line, (2) are that main amalgam storage tube, (4) are blast pipe for coil, (9) for heat radiation lampshade, (10) heat radiation bearing, (11) for re-entrant cavity, (8) for thermal conductor, (6) discharging bulb, (7) for Auxiliary amalgam, (5) for high-frequency electrical component, (3) among the figure.
In Fig. 1, the heat radiation lampshade is approximate parabolic shape, and material therefor is an aluminium; Thermal conductor adopts micro heat pipe; The shell of HF link adopts aluminum.In the specific implementation, should make heat abstractor have enough efficiently radiates heat areas according to the size of electrodeless lamp power.The profile of heat radiation lampshade can adopt approximate parabolic shape, also can adopt other shape, depends primarily on the whole requirement of lighting environment to the lamp outward appearance.When electrodeless lamp power is big (more than the 30W), thermal conductor should be selected heat pipe for use; As power hour (below the 30W), thermal conductor can be selected hollow or solid metal bar for use.
When electrodeless lamp was switched on, the high frequency magnetic field generator had produced high frequency magnetic field, and this high frequency magnetic field excites the mixed gas discharge in the discharging bulb.When gas discharge, it not only produces visible light, more still produces ultraviolet light, owing to scribble fluorescent material on the discharging bulb inwall, makes ultraviolet light be converted to visible light effectively, but a large amount of wind of promptly last generation is seen light.
