Abstract
A high-power electrodeless lamp comprises a sphericity lamp shield, a heat radiator, an electrodeless upper baffle, an electrodeless lower baffle, a control circuit board casing a lamp holder which are connected in sequence, wherein an aluminum bar is arranged in the sphericity lamp shield, one end of the aluminum bar is connected with the heat radiator, and a magnetic ring is arranged on the aluminum bar; a ventilation fan is arranged in a cavity formed between the heat radiator and the electrodeless upper baffle, and is also fixed on the electrodeless upper baffle; an air gap is formed between the electrodeless upper baffle and the electrodeless lower baffle; and a control circuit board is arranged in the cavity formed between the heat radiator and the electrodeless upper baffle. According to the utility model, the ventilation fan and the control circuit baffle are isolated in two different cavities, therefore, the service life of electronic components on the control circuit board is ensured, the ventilation speed of the lamp is improved because the heat radiator is communicated with the external space and is combined with the ventilation fan to form a convection ventilation structure; and besides, the lamp has a simple and reasonable structure, low manufacturing cost and high practicability.
Description
Technical field
The utility model relates to a kind of lighting device, particularly relates to a kind of high-power electrodeless lamp.
Background technology
Electrodeless lamp is that a kind of life-span is long, and light efficiency is high, and the new type light source of obvious energy conservation in the illumination, has consequence in public places.But electrodeless lamp bulb and control circuit are installed in the same sealed environment simultaneously, and heat can't produce heat exchange efficiently with outside air, has reduced the useful life of electrodeless lamp.
Application number is that 200910107990.8 one Chinese patent application discloses a kind of " integrated high-frequency electrodeless lamp "; Have as the radio-frequency generator of head be installed in the HF lamp without electrodes bulb on the radio-frequency generator; Wherein radio-frequency generator is made up of lower case, middle part heat-insulating base, upper case and lamp holder; Owing to be to form the chamber that is communicated with between lower case and the upper case; Therefore the foreign matters such as steam dust that suck during radiator fan work can have influence on the useful life of the electric component on the radio-frequency generator interior circuit board, and radiator is in the chamber that between upper case and lower case, forms of device, can't heat directly be dispersed in the light fixture air outside; Even therefore the auxiliary heat dissipation of radiator fan is arranged, also be difficult to effectively solve the heat dissipation problem of light fixture.
Summary of the invention
The purpose of the utility model is to above-mentioned existing problems and deficiency a kind of heat dissipation problem that can effectively solve light fixture to be provided, and can guarantee the high-power electrodeless lamp of the long service life of electric component on the control circuit board again.
The technical scheme of the utility model is achieved in that
The described high-power electrodeless lamp of the utility model; Be characterized in comprising the globe holder, radiator, electrodeless lamp upper spacer, electrodeless lamp lower clapboard, control circuit board shell and the lamp holder that connect in regular turn; Be provided with aluminium bar in the said globe holder, and an end of this aluminium bar is connected with radiator, said aluminium bar is provided with magnet ring; Be provided with radiator fan in the chamber that forms between said radiator and the electrodeless lamp upper spacer; And this radiator fan is fixed on the electrodeless lamp upper spacer, is formed with air gap between said electrodeless lamp upper spacer and the electrodeless lamp lower clapboard, is provided with control circuit board in the chamber that forms between said control circuit board shell and the electrodeless lamp lower clapboard.
Pass to radiator effectively for heat can be reached fast, above-mentioned aluminium bar and radiator connect as one through riveting.
The utility model is owing to having adopted electrodeless lamp upper spacer and electrodeless lamp lower clapboard that radiator fan and control circuit board are separated the structure in two different chambers; The foreign matters such as steam dust that radiator fan is sucked can't have influence on the electric component on the control circuit board; Thereby guaranteed the long service life of electric component on the control circuit board; And radiator directly is connected with space outerpace, combines radiator fan to form the convection type radiator structure simultaneously, thereby makes the radiating rate of light fixture fast; So just effectively overcome existing heat dissipation problem in the existing light fixture, and simple and reasonable, the low cost of manufacture, practical of the utility model.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
