Abstract
The invention discloses a detection device for light sources of electrodeless lamps. A thermal insulation cover and a thermal insulation base are closely fitted to form a confined space for containing an electrodeless lamp to be detected, and a power supply source supplies electricity for a loop formed by the electrodeless lamp, an electronic ballast and a current detection device. The detection device can effectively detect unaccepted products of the electrodeless lamps and simultaneously can be used as a reminding device for preventing the ballast of the electrodeless lamp from overburning.
Description
Technical field
The present invention relates to a kind of electrodeless lamp source pick-up unit.
Background technology
At present, single-ended electrodeless florescent lamp (being designated hereinafter simply as electrodeless lamp) is with its good energy-conserving and environment-protective performance, be widely applied to various illuminating industries, yet, though more existing electrodeless lamps can normally use in conventional environment, but when under some extraordinary situations, using, for example work as the environment temperature of electrodeless lamp above 100 ℃, found through experiments, some electrodeless lamps are substandard products, because lacking the corresponding techniques means carries out corresponding quality testing in the stage of dispatching from the factory of electrodeless lamp to electrodeless lamp, cause a large amount of defective electrodeless lamps to come into the market, influence user's the use and the further popularization of electrodeless lamp greatly.
Summary of the invention
The object of the present invention is to provide a kind of electrodeless lamp source pick-up unit that electrodeless characteristic of a navigation light amount detects that is used for.
The present invention solves described problem by the following technical solutions: a kind of electrodeless lamp source pick-up unit, stay-warm case closely cooperates with the insulation base and forms the confined space that holds electrodeless lamp to be detected, the loop power supply that power supply forms for described electrodeless lamp, electric ballast, current sensing means.
Preferably, described stay-warm case cover body inwall is smeared heat insulation coating.
Preferably, described heat insulation coating is the Teflon insulation film.
Preferably, described loop is provided with the electric current warning device.
Beneficial effect: the present invention can effectively detect the unacceptable product in the electrodeless lamp, simultaneously, also can be used as alarm set and prevents that the ballast resistor of electrodeless lamp from burning.

Among the figure: 1, current sensing means; 2, electric ballast; 3, heat insulation coating; 4, cover body; 5, stay-warm case; 6, electrodeless lamp; 7, power supply; 8, warning device; 9, insulation base.
Embodiment
Embodiment 1
At first, the origin cause of formation of defective electrodeless lamp product is made following analysis, to prove feasibility of the present invention and necessity:
Respectively get a qualified electrodeless lamp of cover and a defective electrodeless lamp, the power of selected qualified electrodeless lamp and defective electrodeless lamp is 165W, under different temperature environments, variable power to selected electrodeless lamp is measured, measurement result as shown in Figure 2, can draw with reference to experimental data, when environment temperature during at 80-100 ℃, the real power of qualified electrodeless lamp does not have significant change, and the real power of defective electrodeless lamp but obviously increases, and the residing environment temperature of the electrodeless bulb of general built-in light fixture is all about 95 ℃, under this temperature, the real power of electrodeless lamp is with unprecedented soaring, and under the changeless situation of virtual voltage, the nonpolar lamp circuit actual current will significantly increase, as everyone knows, ballast resistor is the topmost components and parts of electrodeless lamp, when actual current surpasses the rated current of ballast resistor, can damage ballast resistor, cause the shortening in serviceable life of electrodeless lamp, therefore, for satisfying the use of user terminal, be necessary defective electrodeless lamp product is detected.
The reason that electrodeless lamp real power increases suddenly is, in the bulb production run, inner vacuum is destroyed, a certain amount of air infiltrates in the bulb, reaching the uniform temperature threshold values, air generation qualitative change in the bulb, cause the bulb internal energy unbalance, bulb power increases rapidly, behind defective electrodeless lamp vacuum breaker, re-fill behind the inert gas by normal operation and to detect once more, electrodeless lamp is working properly, that is to say, the substandard product that is detected not is a waste product, can use after treatment, this has further given prominence to necessity of the present invention and feasibility.
The present invention detects electrodeless lamp by proposing a kind of electrodeless lamp source pick-up unit, stay-warm case 5 closely cooperates with insulation base 9, the confined space of electrodeless lamp 6 to be detected is held in formation, the loop power supply that power supply 7 forms for electrodeless lamp 6, electric ballast 2, current sensing means 1.Stay-warm case 5 cover bodies 4 inwalls are smeared heat insulation coating 3, and cover body 4 adopts the organic glass of Teflon material to make, and heat insulation coating 3 is the Teflon insulation film.Be provided with electric current warning device 8 in the loop of forming by power supply 7, electrodeless lamp 6, electric ballast 2, current sensing means 1.When electrodeless lamp 6 is worked, can produce a large amount of heats, and in above-mentioned confined space, heat distributes seldom, make the temperature in the confined space raise, the environment temperature that makes bulb bear raises, at this moment, if be specification product, the real power of electrodeless lamp 6 can not increase, under the specific voltage condition, its circuit actual current also can remain on a steady state value, at this moment, also will remain on a suitable scope, and can instead release this electrodeless lamp 6 and be specification product by current sensing means 1 detected actual current value; If be substandard product, the real power of electrodeless lamp 6 will increase, under the fixed voltage condition, its actual current will have bigger increase, and when actual current surpasses certain threshold values, warning device 8 will be reported to the police, can instead release this electrodeless lamp 6 and be substandard product, simultaneously, in testing process, the temperature in the stay-warm case 5 can be regulated and control by the thickness of adjusting insulation base 9 or the heat-insulating property of stay-warm case 5.
Following partly providing at the principle of the invention describes in further detail:
After electrodeless lamp 6 is placed in above-mentioned confined space, electrodeless lamp 6 is lighted in energising, heating after electrodeless lamp 6 lamps are bright, make the temperature in the above-mentioned confined space raise, under the normal condition, after half an hour, temperature in the confined space reaches 125 ± 5 ℃, and (environment temperature of the built-in light fixture of general electrodeless lamp is all about 95 ℃, and, as seen from Figure 2, when temperature after 100 ℃, underproof electrodeless lamp power increases rapidly, consider variation of ambient temperature, so after will being incubated case temperature and setting 125 ± 5 ℃ of stay-warm case 5 internal temperatures for and reach setting value, electrodeless lamp 6 heating and stay-warm case self-radiating reach equilibrium point, at this moment, the internal temperature of stay-warm case 5 will remain unchanged, and for the adjusting of this equilibrium point, can by to the heat transfer coefficient of base 9 and or volume regulate realization.
