Abstract
The utility model discloses a time-delay, mild-starting incandescent lamp, which is characterized in that the leading wire (9) of the phase wire of an ordinary incandescent lamp is connected in series with a mild starter (13) which has the characteristic of negative resistance. When the current flow flows through the utility model, a tungsten filament (2) can not be heated to emit light at once, but the tungsten filament is heated gradually to delay lighting, so the instant impact of big current is avoided when the incandescent lamp is started, achieving the purpose of prolonging the service life of lamp bulbs.
Description
The utility model relates to a kind of lighting source, especially the gentle incandescent lamp of being made up of ordinary incandescent lamp and gentle starter that starts of time-delay.
In the at present existing lighting source, though the luminous efficiency of incandescent lamp minimum (about 10Lm/w), average life span the shortest (specified 1000h is about practical 500h), it still has advantages such as processing is simple, easy to use, with low cost and is widely used.
Why above-mentioned physical life is much smaller than the rated life time, this with influence its life-span all multifactor as supply power voltage, power supply character, luminous efficiency, ambient temperature and intermittently light a lamp etc. relevant.But when supply power voltage, character, luminous efficiency, ambient temperature all just often, light a lamp intermittently that it is the most obvious influence bulb life, light a lamp to the intermittence of n second at the hundreds of millisecond as switch periods, will make life-span minimizing 2~8%.This is because tungsten has positive resistance characteristic, and when working temperature, the resistance of resistance during much larger than cold conditions (20 ℃), the thermal resistance of general incandescent lamp filament are tens times of cold resistance, so instantaneously have bigger electric current to flow through what lamp started.Every startup once then influence once, startup frequent more, its influence is big more, then the life-span is short more.Often complain as the user: the frequency lamp, the life-span is short, altar lamp, the electric lighting bill is heavy and cause at a loss as to what to do.
The purpose of this utility model provides the gentle incandescent lamp that starts of a kind of time-delay, and the gentle incandescent lamp that starts of this time-delay can be contained the impact of the instantaneous high electric current of startup to tungsten filament effectively, prolongs the useful life of bulb.
For achieving the above object, solution of the present utility model is: be provided with a gentle start-up circuit of time-delay that is in series by gentle starter and tungsten filament in ordinary incandescent lamp.This circuit one end is connected with phase line, and the other end is connected with the neutral line with tungsten filament.During startup, when electric current flows through this gentle starter, tungsten filament can not add thermoluminescence suddenly, but the time-delay of heating gradually is luminous, and this is because should have negative resistance characteristic by gentle starter, they are when start-up temperature (25 ℃), the resistance of resistance when hot, this moment, resistance was equivalent to the tungsten filament cold resistance nearly a hundred times, started n after second, the gentle complete conducting of starter, this moment, resistance was zero no better than.
Owing to adopted the gentle start-up circuit of time-delay in the above-mentioned solution, thereby can effectively limit the startup transient current, prolong bulb service life, removed the awkward sorrow of user.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the gentle circuit theory diagrams that start the incandescent lamp execution mode of the utility model time-delay;
Fig. 2 is the gentle incandescent lamp cutaway view that starts of the time-delay of execution mode shown in Figure 1;
Fig. 3 is the operation characteristics typical curve chart of Fig. 1 or execution mode shown in Figure 2.
In the gentle startup of time-delay shown in Figure 1 incandescent lamp circuit theory diagrams, phase line 9 is in series with gentle starter 13, tungsten filament 2 and the neutral line 10.
Fig. 2 is the gentle incandescent lamp that starts of time-delay that forms by the foregoing circuit principle diagram design, by glass bulb 1, tungsten filament 2, seal wire 3, molybdenum filament support 4, Dumet wire 5, glass press seal 6, blast pipe 7, weldering mud 8, phase line lead-in wire 9, neutral line lead-in wire 10, lamp holder 11, scolding tin contact 12 with place the gentle starters 13 in the lamp holder 11 to form.Similar by shape in this lamp holder 11, size is greater than the respective cavities 14 of gentle starter 13, and the position of this cavity 14 can make gentle starter 13 just in time be positioned at this cavity 14.Should be connected with tungsten filament 2 by gentle starter 13 1 ends, the other end is connected with lamp holder scolding tin contact 12.
After adopting such frame mode, fuse in the former ordinary incandescent lamp structure and fuse bushing pipe are had simultaneously can prevent that when filament blow the gentle starter 13 that produces the electric arc function from substituting, and gentle starter 13 simple in structure, low prices, this subtracts one and adds and increase cost hardly.
Fig. 3 has provided the gentle operation characteristics typical curve that starts incandescent lamp of time-delay, from figure curve as can be seen the starting current of this incandescent lamp prolong in time and the state that changes.
Certainly; the gentle incandescent lamp that starts of this time-delay; do not limit to and above-mentioned ordinary incandescent lamp cell-shell shape shown in Figure 2, gentle start-up circuit limits the startup transient current to other various typical external form incandescent lamps as long as it has adopted above-mentioned time-delay, also belongs to protection range of the present utility model.
