Abstract
The utility model discloses a lamp string structure comprising a plurality of bulbs in series. Each bulb respectively is connected in parallel with one or more resistances. Each tungsten filament type or LED bulb on the lamp string in series is connected in parallels with one or more appropriate resistances, thereby sharing in the increased voltage through the resistances in case the bulbs fall or burn and maintaining the normal current value to ensure other bulbs working on and preventing the whole string from losing function.
Description
Technical field
The utility model relates to the lamp decoration product technical field, particularly relates to a kind of lamp string structure.
Background technology
In various red-letter days, celebrate occasion joyously, people usually with the various article environment of dressing up, make it have the atmosphere of celebrating joyously; The lamp string is exactly often be used a kind of.Lamp string on the open market is bulb--and the common bulb of-tungsten filament formula or the lamp string that the series connection of LED bulb forms, can cause whole cluster of lamps, ornamental string to lose function when one of them bulb drops or damages.After through the improvement, add that in lamp holder auxiliary component makes lamp string unlikely whole string when opening circuit lose function, is referred to as intelligent lamp string in the industry.
The intelligent lamp string of being produced in the market (one) direct current that is divided three classes adds diode lamp luster (two) and exchanges and to add bilateral diode lamp string (three) and exchange and add shell fragment lamp string.But above three class lamp strings all have certain operating difficulties and danger.Wherein (one) must be divided both positive and negative polarity in production operation, as adorns instead and can cause diode breakdown, causes loss, and (two) bilateral diode price in electronic component is very expensive.(3) is to adopt AC power and shell fragment is set in lamp holder, and two shell fragments when bulb drops in the lamp holder can close, and reach energising.If but the number that bulb drops is too much, make the voltage on the residue bulb surpass rated voltage, the temperature of bulb will constantly be increased, and causes danger.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the above problems, and a kind of lamp string structure that safely, is easy to produce and have high reliability is provided.
For achieving the above object, the utility model has adopted following technical scheme:
The utility model discloses a kind of lamp string structure, formed by a plurality of bulb series connection, each bulb is parallel with one or more resistance respectively.
The resistance of described resistance is greater than the equivalent resistance of bulb in parallel with it.
Described bulb is common tungsten filament formula bulb or LED bulb.
Because adopted above scheme, the beneficial effect that the utility model is possessed is:
1, by the one or more suitable resistance in parallel of each bulb (tungsten filament formula or LED) in Series lamp string, thereby can when bulb drops or burn, share the voltage of increase by resistance, keep current value just often, allow other bulbs work on, can not put in order string and lose function;
2, available alternating current is exported and is not needed through over commutation, therefore can reduce production costs greatly;
3, circuit is simple, and fault rate is low, can improve product quality and output greatly;
4, can reduce the production difficulty: relative Zener diode, resistance can be operated in the communication environment, need not distinguish both positive and negative polarity in assembling, also needn't use instrumentation in maintenance;
5, reliability of products is improved: because resistance is non-crystal element, and the good stability of resistance in hot environment.
Description of drawings
Fig. 1 is a kind of lamp string structure schematic diagram of the present utility model.
Fig. 2 is an another kind of lamp string structure schematic diagram of the present utility model.
The specific embodiment
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
Embodiment 1
As shown in Figure 1.A kind of safety is saved novel intelligent lamp string, is formed by a plurality of common osram lamp series connection.Each bulb also is parallel with a resistance R respectively.And the resistance of resistance R is greater than the equivalent resistance of bulb.
Bulb is installed on the lamp holder, and resistance R also is arranged in the lamp holder.Like this, if there are one or more bulbs to drop or burn from lamp holder in the lamp string, the resistance in the lamp holder can be shared the voltage of increase so, keeps current value just often, allows other bulbs work on, and can not put in order string and lose function
Embodiment 2
As shown in Figure 2, a kind of Novel LED light string is formed by a plurality of LED bulb series connection, simultaneously, is in series with resistance R in the circuit
0At each R
0Also be parallel with resistance R with the LED bulb side, and the resistance of resistance R is greater than R
0Total equivalent resistance with the LED bulb.When one or more LED bulb burns or connects inverse time, resistance R can work on other bulbs, can not put in order string and lose function.
Claims (3)
1, a kind of lamp string structure is formed by a plurality of bulb series connection, and it is characterized in that: each bulb is parallel with one or more resistance respectively.
2, lamp string structure according to claim 1 is characterized in that: the resistance of described resistance is greater than the equivalent resistance of bulb in parallel with it.
3, lamp string structure according to claim 1 and 2 is characterized in that: described bulb is common tungsten filament formula bulb or LED bulb.
