Abstract

The utility model discloses a high voltage-resistant energy-saving lamp which can be used for high voltage of 380V. The high voltage-resistant energy-saving lamp is composed of a lamp cap, a lamp socket and two lamp tubes. The high voltage-resistant energy-saving lamp is characterized in that the lamp filaments which are arranged inside the two lamp tubes are connected in series. The high voltage-resistant energy-saving lamp has the advantages of simple structure, convenient manufacture, low cost, and wide range of application. The utility model does not need a lot of investment and a dedicated line to realize the industrialization of large batch and the generalization and use of a large area.

Description

High pressure resistant electricity-saving lamp

The utility model belongs to lighting technical field.

Current, the rated voltage of the employed civilian alternating current lighting of people is generally 220V, and the fluctuation range up and down of its voltage must not surpass 10-15%; Voltage is too low, the luminous dimness of lighting or at all do not work; Voltage is too high, and lighting can be burnt.And at present, do not have the domestic lighting light fixture that can use the 380V high pressure on city's field boundary again, like this, bring very big inconvenience can for undoubtedly the field work of not setting up the domestic lighting circuit.If, set up a domestic lighting circuit specially for the farmland farm work at night of a certain surprise or a certain field work, perhaps add transformer and carry out step-down and handle, this not only needs to increase very big investment, and is unpractical.

In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of any potential device and set up the dedicated illumination circuit of need not increasing, and both can use under 220V voltage, again the high pressure resistant electricity-saving lamp that can use under the 380V high pressure.

The purpose of this utility model is achieved like this:

The utility model is a theoretical foundation with ohm theorem: V=IR, according to passing through in maintenance under the constant preceding topic of light fixture heater current, strengthen the internal resistance of light fixture, can improve withstand voltage this principle of light fixture, based on existing two-tube electricity-saving lamp, the connected mode of the filament of its fluorescent tube to be improved, the parallel way that also is about to former two-tube energy-saving lamp filament changes the mode of series connection into, perhaps the filament with the civilian incandescent light bulb of two 220V adopts the mode of series connection to couple together, to increase its internal resistance.Like this, can make and originally withstand voltagely bring up to withstand voltage 380V for the domestic lighting light fixture of 220V.

Through the utility model after the above-mentioned improvement, simple in structure, easy to make, cost is low, widely applicable, it both need not increase a large amount of investments, also need not install potential device additional and add special-purpose illuminating line, can realize industrialized production in enormous quantities and large-area promoting the use of.

Specific embodiments of the present utility model is as shown in drawings:

Fig. 1 is the structural representation of existing two-tube electricity-saving lamp

Fig. 2 is a structural representation of the present utility model

Below in conjunction with accompanying drawing, concrete structure of the present utility model and embodiment are elaborated:

High pressure resistant electricity-saving lamp is made of lamp holder 1, lamp socket 2 and two 3,4 of fluorescent tubes, is arranged at filament 5,6 filament 7,8 interior with being arranged at fluorescent tube 4 in the fluorescent tube 3 and is and is connected in series; The lead-out wire of the filament 8 in filament 5 in the fluorescent tube 3 and the fluorescent tube 4 is connected with the two poles of the earth power connection on the lamp holder 1 respectively.High pressure resistant electricity-saving lamp also can be in series by the incandescent lamp bulb of two 220V to form or be in series by the lamp socket of the incandescent lamp of two 220V and form.The lamp holder 1 of high pressure resistant electricity-saving lamp can adopt plug-in lamp holder or screw-type lamp holder, so that make the supporting use of civilian lamp socket of itself and existing various models, like this, can make it have good versatility.

High pressure resistant electricity-saving lamp can directly use the commercial power of 380V, and during use, the lamp holder of high pressure resistant lamp need only be connected with two power lines gets final product; Also can directly use the civilian electricity of 220V, its brightness is unaffected.
