Along with popularizing of remote control lamp, on light fixture, the infrared remote control receiving amplifier product of demand gets more and more.Light fixture is different from other electrical equipment, and the illumination meeting direct projection infrared remote control receiving amplifier that light fixture sends, can cause photosensitive saturated, the normal work of interference infrared remote control receiving amplifier.And the electromagnetic wave of light fixture radiation also can produce interference to infrared remote control receiving amplifier.The infrared remote control receiving amplifier product of remote control lamp is assemblied in inside light fixture, and light interference strength is comparatively large, and common infrared remote control receiving amplifier is difficult to suppress so strong light interference.
Utility model content
For the existing infrared remote control receiving amplifier be arranged in light fixture, to the lamp weak point of controlling of disturbing light, the utility model proposes a kind of novel infrared remote control receiver amplifier, the anti-light interference performance of this novel infrared remote control receiver amplifier is stronger, highly sensitive.
The utility model adopts following technical scheme:
A kind of novel infrared remote control receiver amplifier, comprise infrared receiving module, filtering circuit, metal screening can and optical filter, be electrically connected between infrared receiving module and filtering circuit, and it is on circuit boards integrated, circuit board is arranged in screening can, screening can is provided with window, and optical filter is located at the window place of screening can, and the receive window of infrared receiving module is positioned in the light path of optical filter.
Further, filtering circuit is connect electric capacity between the power end and earth terminal of infrared receiving module.
Further, optical filter is bandpass filter.
Further, screening can is iron shell.
Existing infrared remote control receiving amplifier anti-interference is the mode by adopting inner screening or external shield iron-clad, and this mode is sorry and is filtered the intense laser interfere of light fixture.The utility model, for remote control lamp, proposes the infrared remote control receiving amplifier that a kind of anti-light jamming performance is good.The utility model, by increasing the Conduction Interference of filter capacitor filter out power end, adopts the Electromagnetic Interference of screening can shielding light fixture radiation, then increases optical filter, filter out other light source except Infrared remote controller useful signal.Shield from many aspects, improve the ability of the anti-light interference of infrared remote control receiving amplifier, the utility model is applicable to remote control lamp field.

Embodiment
For further illustrating each embodiment, the utility model provides accompanying drawing.These accompanying drawings are a part for the utility model disclosure, and it is mainly in order to illustrate embodiment, and the associated description of instructions can be coordinated to explain the operation principles of embodiment.Coordinate with reference to these contents, those of ordinary skill in the art will be understood that other possible embodiments and advantage of the present utility model.Assembly in figure not drawn on scale, and similar element numbers is commonly used to assembly like representation class.
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
Consult shown in Fig. 1 to Fig. 4, the novel infrared remote control receiver amplifier of the preferred embodiment of the utility model, it comprises infrared receiving module 1, filtering circuit, screening can 3 and optical filter 4, wherein, infrared receiving module 1 is electrically connected with between filter capacitor, and both are integrated on one piece of circuit board.Circuit board is arranged in screening can 3, and screening can 3 is provided with window, and optical filter 4 is located at the window place of screening can 3.
Consult shown in Fig. 1, the filtering circuit of this embodiment is connect filter capacitor C between the power end and earth terminal of infrared receiving module 1, the Conduction Interference making this embodiment can well suppress power supply to produce.This embodiment also with the addition of current-limiting resistance R2 at the power end of infrared receiving module 1, for the electric current in limiting circuit; In addition, this embodiment with the addition of pull-up resistor R1 between the power end and output terminal of infrared receiving module 1, improves antijamming capability.
It should be noted that, between the power end that filter capacitor C is connected to infrared receiving module 1 by this embodiment and earth terminal, also can by between the power end of its infrared receiving module 1 and output terminal or between output and ground.In addition, the filter capacitor C of this embodiment only has one, those skilled in the art is known, and filtering circuit also can comprise two or three filter capacitors, is connected to by filter capacitor C between the power end of infrared receiving module 1, any two ports of output and ground.
Infrared receiving module 1, filtering circuit, pull-up resistor R1 and current-limiting resistance R2 are integrated on one piece of circuit board by this embodiment.Consulting shown in Fig. 2 and Fig. 3, is the pro and con of the printed board of this circuit board.Be equipped with infrared receiving module 1 and row's pin in the front of printed board, the pin wherein arranging pin for user when assembling; Two filter capacitor C1 and C2, pull-up resistor R1 and current-limiting resistance R2 is equipped with at the back side of printed board.Filter capacitor C2 is as subsequent use, if the effect of filter capacitor C1 is bad, filter capacitor C2 can be connected to infrared receiving module 1 output and ground or between power end and output terminal.
Again consulting shown in Fig. 4, is the schematic diagram of this embodiment.The printed board that components and parts are housed is located in screening can 3 by this embodiment, and screening can 3 stays a window for assembling optical filter 4 in infrared remote control receiving amplifier land portions, and printed board is wrapped up by remainder completely.Screening can 3 makes this embodiment have the feature of electromagnetism interference, anti-light interference, and possesses that receiving sensitivity is high, angle is wide equally.
