Background technology
refrigerator has become the important composition composition that people live in current society, and frequency of utilization is opened or closes in life in a day.Refrigerator all is to open the door in the top, the cabinet door that it comprises the cabinet of open top and is installed in cabinet open top place.Illumination in the cabinet all is equipped with the lamp source in the inside of refrigerator for ease.The lamp source was unlocked when its significant characteristic of the lamp source of this refrigerator was turned on the cabinet door exactly, and the lamp source is in time closed when closing the cabinet door, so in the lamp source of all refrigerators the gauge tap that can control its unlatching or cut out must arrange.The gauge tap that adopts in the refrigerator all be adopt mechanical, this type switch, when the door of refrigerator or refrigerator opened or closed, push rod promoted gauge tap contact closure or disconnecting circuit, thereby opened bright or extinguish the lamp source.Owing to reasons such as wearing and tearing, dusts, this type switch or push rod are often malfunctioning easily, make troubles for user and manufacturer.
The utility model content
to the problems referred to above, the purpose of the utility model provides the lighting device of the high refrigerator of a kind of reliability.
are in order to realize above-mentioned utility model purpose; The utility model adopts following technical scheme: a kind of lighting device of refrigerator; The cabinet door that is installed in described cabinet top that this refrigerator comprises the cabinet of open top, can rotate through a horizontal rotating shaft; Described lighting device is arranged on the inside of described refrigerator; It is characterized in that: described lighting device comprises light source, the driving power that is electrically connected with described light source, be used to control the whether mercoid switch of conducting of described driving power and described light source; Described mercoid switch is arranged on the described cabinet door, being electrically connected between conducting driving power and described light source when described mercoid switch turns to horizontal by set angle at described cabinet door around described horizontal rotating shaft.
In
such scheme, preferably, described lighting device is arranged on the internal face of the cabinet door of being told.
In
such scheme, preferably, described light source comprises the LED lamp that a plurality of parallel connections are provided with.
In
such scheme, preferably, described driving power is non-isolation constant-current driving power supply.
further, described non-isolation constant-current driving power supply, mercoid switch and a plurality of LED lamp source are arranged on the same circuit board.
the utility model compared with prior art has following advantage: the mercury vapor lamp construction of switch of the utility model is simple, be active in one's movements the advantage of long working life.
Description of drawings
Accompanying drawing 1 is the three-dimensional structure diagram of the utility model;
accompanying drawing 2 is the lighting unit sketch map of the utility model.
In
accompanying drawing, 1, cabinet; 2, storage chamber; 3, cabinet door; 4, horizontal rotating shaft; 5, lighting unit; 6, non-isolation constant-current driving power supply; 7, mercoid switch; 8, light source; 9, panel.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, the utility model is done further to describe in detail below in conjunction with accompanying drawing:
refrigerator shown in accompanying drawing 1, this refrigerator has the cabinet 1 of an open top, the cabinet 1 inner storage chamber 2 that forms, the open top place of cabinet 1 is provided with a cabinet door 3.Cabinet door 3 is hinged on the top of described cabinet 1 rear wall through a horizontal rotating shaft 4.Be provided with the sealing strip (not shown) around the cabinet door 3, when cabinet door 3 is closed, seal between the top of cabinet door 3 and cabinet 1.The middle part of cabinet door 3 inwalls is provided with lighting unit 5, and lighting unit 5 can provide lighting source to the user when cabinet door 3 is opened, and when cabinet door 3 is closed, and lighting unit 5 is in time closed for economize on electricity.
are as shown in Figure 2, the light source 8 that the non-isolation constant-current driving power supply of lighting unit 5 bag 6, mercoid switch 7 and a plurality of LED lamps that are provided with by a plurality of parallel connections constitute.The light source 8 that non-isolation constant-current driving power supply 6, mercoid switch 7 and a plurality of LED lamp constitute is arranged on the same circuit board, and described circuit board is electrically connected the light source 8 that non-isolation constant-current driving power supply 6, mercoid switch 7 and a plurality of LED lamp constitute.In the present embodiment, non-isolation constant-current driving power supply 6 is electrically connected with light source 8.Mercoid switch 7 is used to control whether conducting of driving power 6 and light source 8.Mercoid switch 7 is arranged on the cabinet door 3, being electrically connected between conducting driving power 6 and the light source 8 when mercoid switch 7 turns to horizontal by set angle at cabinet door 3 around horizontal rotating shaft 4, and mercoid switch 7 itself can detect opening or closing of cabinet door 3.
The course of work of
the utility model is: when refrigerator was opened, cabinet door 3 rotated around horizontal rotating shaft 4, thereby mercoid switch 7 rotates; After cabinet door 3 is opened to set angle, (be that mercoid switch 7 is horizontal by set angle; Run-off the straight), mercoid switch 7 detects the unlatching of cabinet door 3, and mercoid switch 7 is unlocked; Circuit between non-isolation constant-current driving power supply 6 and the light source 8 is switched on, and non-isolation constant-current driving power supply 8 is given light source 8 through mercoid switch 7 continued powers; When refrigerator was closed, cabinet door 3 was around horizontal rotating shaft 4 backward rotation, thus mercoid switch 7 backward rotation; When cabinet door 3 was closed, mercoid switch 7 detected cabinet door 3 and cuts out, and mercoid switch 7 is closed; Circuit between non-isolation constant-current driving power supply 6 and the light source 8 is swashed to be broken off, and light source 8 extinguishes.
More than the utility model has been done detailed description; Its purpose is to let the personage that is familiar with this art can understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of doing according to the spirit of the utility model change or modify, and all should be encompassed in the protection domain of the utility model.
