Existing Chinese patent notification number is that CN202093674U discloses a kind of luminous remote controller, include body, be located at display part and a plurality of button on the body, the button back side is provided with backlight, described button includes at least 2 groups, every group of button back side correspondence is provided with one group of backlight, and every group of backlight is connected directly to master chip or is connected to master chip by backlight source driving circuit, and wherein one group of button is the noctilucence key.This luminous remote controller is divided at least 2 groups with button and the backlight corresponding with button, controls respectively, lights not the pairing backlight of button on the same group according to user's needs, reaches the purpose of energy saving.
Present air-conditioning remote control is generally with the end backlight scheme as air-conditioning remote control backlight, and end EL sheet and the EL piece driving circuit of in hardware circuit design, needing backlight.The more complicated relatively cost of driving circuit is higher, and serviceable life is shorter, not enough power saving environmental protection, and radiation height.
The utility model content
At the shortcoming of prior art, the utility model provides a kind of telepilot that can be used for household electrical appliance such as air-conditioning and be suitable for using night the band backlight, and the side-light type back light that is electrically connected with driving circuit, energy saving are set at the display screen back side.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of telepilot comprises body, and described body is provided with display screen and a plurality of button, and button is electrically connected with control circuit, and the described display screen back side is provided with side-light type back light, and side-light type back light is electrically connected with driving circuit, and driving circuit is electrically connected with control circuit.Side-light type back light is arranged at both sides backlight to light source, and the adjustment of layout has significantly reduced the use of light source, thereby has reduced production cost and energy consumption, reaches the purpose of energy saving, environmental protection.
Preferably, described side-light type back light is a LED side-light type pipe backlight.The LED light fixture has multiple benefits such as energy saving, and side-light type back light is arranged at both sides backlight to the LED-backlit pipe, or both sides or the right and left up and down, and the adjustment of layout has significantly reduced the use of LED, has further reduced production cost and energy consumption.
In the such scheme, described driving circuit comprises resistance, triode and another resistance that is electrically connected with control circuit, one end ground connection of described resistance, the other end are connected with the negative electrode of LED side-light type pipe backlight, the anode of LED side-light type pipe backlight is connected with the collector of triode, the base stage of described triode is connected with an end of another resistance, and the other end of another resistance is electrically connected with control circuit.
Alternatively, the described button back side is provided with backlight.In like manner, the backlight at the button back side also can adopt the side-light type back light setting, energy saving, environmental protection more.
Compared with prior art, the beneficial effects of the utility model are:
The utility model can be used for household electrical appliance such as air-conditioning and is suitable for using night the telepilot of band backlight, the side-light type back light that is electrically connected with driving circuit is set at the display screen back side, side-light type back light is arranged at both sides backlight to light source, the adjustment of layout has significantly reduced the use of light source, thereby reduced production cost and energy consumption, reached the purpose of energy saving, environmental protection.
