Abstract

The utility model relates to a small electronic night lamp, which comprises a plug, a lamp casing and a luminous element circuit, wherein, a luminous element is composed of two sets of high brightness LEDs. The utility model has the advantages of small size, low power consumption, no emitting heat and long service life. The utility model is mainly used for night illumination in families, and can be used as a lamp which burns day and night for power supply indication.

Description

The electronics mini light night

The utility model relates to a kind of mini light night, and especially adopting high brightness LED is light emitting source, power saving, durable electronics mini light night.

At present, the mini light night of use generally has two kinds, i.e. incandescent lamp and fluorescent tube, because incandescent lamp and fluorescent tube in use can generate heat, and power consumption big (1.5W-10W), and also service life is short, generally at 1000 hours-1500 hours, needs often to change.

The purpose of this utility model provide a kind of volume little, do not generate heat, the electronics mini light night of low in energy consumption, long service life.

The purpose of this utility model is achieved in that it is light-emitting component that the utility model adopts high brightness LED, and it comprises plug, lamp housing and light-emitting element circuit.Its circuit connecting relation is: after order is connected separately by two groups of high brightness LEDs, reverse parallel connection again, connect with a current-limiting resistance (R), a decompression capacitor (C) and switch (K), the two ends of circuit are the two ends and the power input of attachment plug respectively again.Because alternating current in the process of electric capacity charge and discharge, makes the positive half cycle of electric current, negative half period can both obtain complementation in arbitrary group of light emitting diode and work, and reaches luminous purpose.

Owing to adopt such scheme, make mini light night have simple in structure, volume is little, do not generate heat, the advantage of (0.1W-0.2W) low in energy consumption, long service life (more than 100,000 hours).

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is circuit theory diagrams of the present utility model.

Fig. 2 is the structural representation of the utility model embodiment.

Among the figure, 1, Transparent lamp shade 2,lamp socket 3,4, attaching plug

K, switch C, electric capacity R, current-limiting resistance

D1, D2, D3, D4, D5, D6, high brightness LED

In Fig. 1, after two groups of high brightness LEDs (D1-D6) were connected separately in proper order, reverse parallel connection was connected with current-limiting resistance (R), electric capacity (C), switch (K) more again, and the two ends of circuit are attachment plugs (3,4) end respectively.

In Fig. 2, by two groups of high brightness LEDs (D1-D3, D4-D6) order series connection respectively, with one group of light emitting diode (D1-D3) and another group light emitting diode (D4-D6) reverse parallel connection, connect again a current-limiting resistance (R) and a decompression capacitor (C), and be fixed on the lamp socket (2), be arranged in the Transparent lamp shade (1), the two ends of circuit connect attaching plug (3,4) respectively by switch (K), have so just formed that volume is little, the electronics mini light night of energy saving, long service life.

Claims (1)

1, a kind of electronics mini light night is made up of plug, lamp housing, light-emitting element circuit, it is characterized in that: the illuminating circuit part is made up of two groups of high brightness LEDs, after two groups of high brightness LEDs are connected separately in proper order, reverse parallel connection is connected with a current-limiting resistance, decompression capacitor, a power switch more again.
