Abstract

The utility model provides a multifunctional integrated time-delay acousto-optic controlled energy-saving lamp for a stairway, which is composed of four parts, namely, a power supply, a control circuit, a luminous body and a lamp shade, and a UHB ultrahigh brightness semiconductor LED with ultrahigh luminous efficiency is particularly adopted as a luminous element. The control circuit converts the received sound of footsteps or talks of pedestrians into an electric signal for amplification and switches on a power supply of the luminous body to enable the lamp to go on, and the lamp automatically goes off after a period of delay. The lamp does not go on at daytime but only at night. The lamp is very energy-saving, pollution-free and long in service life. With an integrated structure and a long service life, the lamp can avoid the problem of the frequent replacement of the conventional acousto-optic controlled switch and incandescent lamp for the stairway. Since the switching on and off of the lamp causes no electric spark, the lamp can avoid triggering the explosion of accidentally leaked gases, and is very safe and reliable.

Description

Acousto-optic control corridor multifunctional all electricity-saving lamp

Affiliated technical field

The utility model belongs to the lighting device, has energy-conservation characteristics especially, also has remote control and non-contact safety switch characteristics, and its remote signal is pedestrian's footsteps or the natural daylight around voice and the light fixture.

Background technology

A variety of corridor acousto-optic control luminous lamp switch are arranged in the market, and it is not a complete light fixture, also needs supporting other light fixture, generally is incandescent lamp, and they all often damage easily.Need professional electrician change after having damaged this switch or coupled incandescent lamp, very inconvenient.The utility model is very advanced in this respect, has overcome these problems, and it is to have the integrated light fixture that light fixture that sonic-opticalcon trolled switch and superhigh brightness LED (being called for short the superbright pipe) make combines.

Summary of the invention

It is a kind of simple in structure that the utility model purpose is to provide, and has the control integrated corridor time-delay electricity-saving lamp of acousto-optic.It is to constitute incorporate light fixture by power supply, control circuit, the luminous element and the shell that are made by the superbright pipe; Control circuit is made up of transducer, amplifier, delay switch again.Can only see lamp holder joint, outer cover and luminous element three parts in appearance, as shown in Figure 1; Remainder is positioned in the shell.Because luminous element is that the superbright pipe makes, the life-span is extremely long not fragile, does not need frequent replacing; Because it is superbright pipe luminous efficiency extra-high-speed, therefore energy-conservation especially again, and do not have because of there being mechanical contact switch and produce the characteristics that the electric spark problem makes that use is extremely safe.

Description of drawings

Fig. 2 is a basic electronic-circuit diagram of the present utility model.

Fig. 3 increases few element but the electronic-circuit diagram of the better utility model of performance on Fig. 2 basis.

Embodiment

Shell shape of the present utility model as shown in Figure 1, (1) expression lamp holder joint, be fixedly to get on the lamp holder joint that electric bulbs factory produces, (2) expression plastic housing, (3) expression luminous element, be by some superbright pipes and be unified in the lump joint, be connected into superbright pipe group by some and joint again, superbright pipe bond pads is formed in printed board.

The basic electronic circuit of the utility model comprises power supply and control circuit as shown in Figure 2; Control circuit comprises transducer, amplifier, delay switch again.(1) and (20) is transducer among the figure, and (1) is Electret condenser microphone, and (20) are photo resistance.Amplifier is made up of resistance (2), electric capacity (3), (4), resistance (5), (6), (7), (9), amplifier (8a).The delay switch level is made of monostable level and one-way SCR (22), and the monostable level is by diode (10), resistance (11), (12), (13), electric capacity (14), amplifier (8b), resistance (15), (19), (21), photo resistance elements such as (20) is formed, it is subjected to from the low level triggering of amplifier output and overturns, but the resistance value of photo resistance by day (20) becomes enough low because of having than strong illumination, no longer can output low level make amplifier controllable silicon (22) remove conducting through the output clamper of resistance (19) at high level, make power supply Vg be shorted to ground always, therefore this light fixture can not be lighted by day, has only just might light evening; Two amplifier 8a here and 8b are two amplifier unit in the integrated circuit; Power supply has two groups, constitutes power supply v+ by electric capacity (32), resistance (29), rectifier diode (25), (26), voltage stabilizing didoe (24), electric capacity (23), and it is this lamp interior working power; Constitute power supply Vg by electric capacity (35), resistance (34), rectifier diode (27), (28), (30), (31), electric capacity (33), it is the power supply of luminous element (36).Above electronic circuit (except that luminous element) all is welded on the main circuit board.Luminous element (36) is a superbright pipe group, and it is welded on separately in the luminous element printed board.Transducer (1) receives the signal of telecommunication that produces through corridor pedestrian's footsteps or voice and amplifies through amplifier and trigger output low level after the monostable in the delay switch level and remove to cut out controllable silicon (22) in the corresponding levels, is shorted to ground and the luminous element normal power supply is lighted light fixture thereby power supply Vg is removed.Restore via monostable after the time of delay of resistance (13) and electric capacity (14) decision, just remove to open controllable silicon (22), thereby make power supply Vg by short circuit and no longer to the luminous element power supply and extinguish light fixture through resistance (19) output high level.

Fig. 3 is the functionally similar circuit that increases a positive-negative-positive triode (16), diode (17), electric capacity (18) back formation on Fig. 2 basis in monostable again, but monostable upset was quicker, more perfect after these three elements had been arranged.The capacitance value of electric capacity among the figure (18) has been amplified its multiplication factor β doubly by triode (16), has been equivalent to increase greatly the capacitance of electric capacity (14), thereby obtains the bigger time constant of monostable level.

Because of this light fixture does not have switch with mechanical contact, no electric spark produces, so use safer.Extremely long because of the superbright tube lifetime, can reach 100,000 hours, thereby it is also extremely long to make this lamp life of luminous element with the superbright pipe.
