Description

Easy-mounting & dismounting energy-saving protector for street lamps

The utility model relates to the energy-conservation and overvoltage protection of incandescent lamp, particularly to the utensil of the energy-saving protective of incandescent street lamp.

Present many units continue to use incandescent lamp as the street lighting at night always, easily electric light is burnt out night in the big minor scale power net of voltage fluctuation round the clock power supply area, moreover street lamp do not need very big brightness, light yellow is wasted a large amount of electric energy whole night.For saves energy and the protection electric light is unlikely burns because of overvoltage, the simplest guard method that many units adopt the always usefulness that exactly two bulbs is together in series.Can increase installation cost but do like this, cause a large amount of wastes.And the way of the simplest maturation of introducing on some radio books and periodicals is exactly diode of string in circuit; utilize the unilateral conduction of diode that electric main is carried out halfwave rectifier; utilize low pressure (about 99V) Rectified alternating current after the rectification to bulb powered, thereby play purpose energy-conservation, protection.Also have other various circuit, but not only valency height (bulb relatively) but also complexity.More than various circuit all very inconvenient in actual use, not only load and unload cumbersomely, and expense height is so can not popularize.

The utility model is mainly incandescent street lamp and also can makes family expenses incandescent lighting lamp one simply energy-conservation, keeping device easy to loading and unloading is provided.

The purpose of this utility model is achieved in that still to utilize and is connected in series diode rectification in the line.Ingenious part is in the design of wiring board, makes it have only size as one piece of two coin-dividing.Because of existing most bulbs are all used bayonet cap, after bulb is packed lamp holder into, because the joint pin in the lamp holder is a rubber-like, also can extrude certain clearance between the joint pin in bulb top and the lamp holder, this utensil can be pressed between space between bulb and the lamp holder easily.After loading onto this utensil, a joint pin directly is communicated with bulb, another joint pin then is communicated with bulb after being contained in the diode on the wiring board, thereby has realized the halfwave rectifier to alternating current.During use, to just in time putting into this utensil, load onto bulb in lamp holder, the time spent does not take off bulb and just it can be taken out, and the loading and unloading that make this energy-conservation protector equally conveniently become possibility with the loading and unloading of bulb.

The utility model only is conceived to installing of rectifier diode, so overall structure and circuit are very simple, does not need any lead to connect, and the side of occupation of land must not add any annex yet.Behind the lamp holder that bulb is changed into the band socket, also can be some low-power (deciding) pure resistive electrical appliance and do the reduction power saver use on the rectifier diode capacity, make this utensil multifunction.Because this utensil only need so cost is extremely low, be easy to realize with the two-sided copper clad plate of a rectifier diode, a slice 3 centimeter square.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.

Fig. 1 is section of the present utility model and corresponding front view.

Describe details in detail below in conjunction with Fig. 1 according to the concrete utensil that the utility model proposes.

This utensil comprises 2.05 centimetres of a slice diameters, the wiring board (1) that thick 0.05 centimetre circular two-sided copper clad plate is made, a rectifier diode (2) is housed on it, and its electrode is welded on the Copper Foil (3) of front (component side), and another electrode is welded on the back Copper Foil (4).(6), (7) be respectively the positive and negative solder joint, solder joint (7) must not exceed 0.10 centimetre.Hole (5) at the offside of wiring board one Copper Foil 0.55 centimetre of diameter of ground drill with ferrule of half from the center of circle.

In conjunction with Fig. 2, use of the present utility model and working condition are described.

Towards lamp holder (10), packed into joint pin (12), (13) that the hole (5) on the wiring board (1), Copper Foil (3) align respectively in the lamp holder (10) in this utensil front, load onto bulb (11) then and get final product.At this moment direct and bulb end tin point (8) connection of the joint pin (12) in the lamp holder (10), and another joint pin (13) is connected with Copper Foil (3) earlier, Copper Foil (4) by reverse side is connected with tin point (9) again after diode (2) rectification, has so just finished switching process.Unload bulb and can take off this utensil easily.

Claims (4)

1, as the road lamp energy-saving protector of the conveniently assemble and disassemble of incandescent lamp, particularly incandescent street lamp; this utensil has circular wiring board (1); rectifier diode (2) is equipped with in its center; it is characterized in that wiring board left side one side of something has an aperture (5); respectively there are fan-shaped Copper Foil (3), (4) in right half of positive and negative, and diode two electrodes connect Copper Foil (3), (4) respectively.

2, the road lamp energy-saving protector of conveniently assemble and disassemble according to claim 1 is characterized in that circular circuit board diameter is 2.05 centimetres, thick 0.05 centimetre.
