Abstract
The utility model discloses a LED sensing lamp with voice suggestion function, which comprises a sensing element, a control circuit connected with the sensing element, a working power supply circuit connected with the sensing element and a control circuit. An LED is connected with the output end of the control circuit and the working power supply circuit; an voice chip is connected with the working power supply circuit; and a speaker output is connected the voice chip. The lamp has the advantages of high reliability, great energy-saving effect, environmental friendliness, miniaturization, and low cost. Equipped with the voice chip, under control of the sensing element, the lamp can give sweet humanized suggestion of fire protection, stair, etc., so as to realize high economic and social benefits.
Description
Technical field:
The utility model relates to a kind of corridor sensing lamp, and especially a kind of is lighting source and the sense light with sound prompt function with LED.
Background technology:
At present, the sense light that is applied to corridor all is provided with sensing elements such as far infrared, acoustic control, be connected to control circuits such as controllable silicon with sensing element, the output and the lighting source of control circuit join, be connected to working power circuit with sensing element, control circuit, mains lighting supply, working power circuit and civil power (220V) power supply joins, and output is fit to the voltage of each element work after transformation, rectification.Be provided with light-sensitive element simultaneously, with the work when corridor is dark of control sense light.Because sense light works in frequent keying state, as adopt the gas discharge electricity-saving lamp as lighting source, then its useful life shorter, and fluorescent tube in contained mercury can cause environmental pollution, therefore existing sense light substantially all be with incandescent lamp as lighting source, exist following shortcoming:
1. adopt the power supply of power frequency all-wave, can since frequent open and close impulse current greatly (impulse current was bigger when night, supply power voltage was high) shorten actual life of incandescent lamp bulb, and control elements such as controllable silicon there is higher requirement, has reduced the reliability of sense light;
2. adopt the power supply of power frequency half-wave, meeting makes illuminating effect not good enough owing to power supply deficiency, photoelectric conversion efficiency are low, will expend more electric energy as keeping with equiluminous;
3. without any sound prompt function, can not make various promptings such as security against fire, floor, use inconvenience.
Summary of the invention:
The utility model is low at the existing in prior technology reliability, technical problems such as voice suggestion, the LED sense light that provides a kind of energy-saving and environmental protection to have sound prompt function are not provided.
Technical solution of the present utility model is: a kind of LED sense light with sound prompt function, sensing element is arranged, be connected to control circuit with sensing element, sensing element, control circuit and working power circuit join, be connected to LED with the output and the working power circuit of control circuit, also be connected to speech chip with working power circuit, the output and the loud speaker of speech chip join.
Be connected to the EMI power-supply filter with the input of working power circuit.
Described sensing element is a Fresnel far infrared sensing element.
The utility model is to be lighting source with LED, have reliability height, energy-saving effect significantly, remarkable advantage such as good environmental protection, microminiaturized cost be low, the particularly supporting speech chip that is provided with, can send melodious hommization prompting language by sensing element control, can in time make public good promptings such as various fire-fightings, floor, have high economic benefit and social benefit to people.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model, as shown in Figure 1: the utility model embodiment is provided with sensing element, and sensing element can be Fresnel far infrared sensing element, acoustic control element or the like.Identical with prior art, be connected to the SCR control circuit with sensing element, sensing element, control circuit and working power circuit join and are provided with light-sensitive element.Be connected to LED with the output and the working power circuit of control circuit, also be connected to speech chip with working power circuit, the output and the loud speaker of speech chip join.Speech chip can adopt various models, and its volume, tone, time can be preset and be regulated also and can reset.In order to prevent that power line from disturbing the operating state of sense light, can be connected to the EMI power-supply filter with the input of working power circuit.By corridor, sensing element sends signal as the people, can send various voice suggestions through time-delay several seconds (adjustable) when sense light is opened illumination (or by light-sensitive element control sounding on daytime).
