Abstract
The utility model discloses a small light-emitting diode night light which comprises a casing (1), a support rib (11), a power part (2), a lighting part (3), a switch (4) and a translucent window (5). The lighting part (3) comprises at least two chromatic light-emitting elements (31) of the luminous diode and a circuit board (32) which is provided with the light-emitting elements (31). The power part (2) in the casing (1) comprises a power warehouse (21). The voltage transformation power (22) sold in the city is embedded in the power warehouse (21) by safety certification. A base pin (222) of the voltage transformation power (22) is extended out of the outer surface of the casing (1). The small light-emitting diode night light is provided with safety use and abundance of colors. Because the voltage transformation power adopts the power assembly which is sold in the city and has the safety certification, the small night light does not need the safety certification again. The small light-emitting diode night light is reliable and has low cost and can be easily accepted by the market.
Description
Technical field the utility model relates to lighting device, particularly is used for the device of indication at night or the illumination of local low-light.
The existing mini light night that is used for indication at night or the illumination of local low-light of background technology generally all is to adopt 220 volts bulb, and this mini light night is not to adopt safe voltage, causes electric shock easily, and color is relatively more dull, and sight is not strong.
Summary of the invention the utility model adopts the light emitting diode of a plurality of different colours as light-emitting component, and rich color is safe in utilization.
Design of the present utility model is as follows: make a kind of light emitting diode mini light night, comprise housing that two parts fasten to form internal cavities with and the inner bearing rib that is provided with.Power supply unit and Lighting Division, the light inlet window that also is provided with switch and Lighting Division light is appeared on this housing, described switch is controlled being switched on or switched off of power supply unit and Lighting Division; Described Lighting Division comprises the light-emitting component of at least two colorful light-emitting diodes and the circuit board of light-emitting component is installed, be connected in after these two light-emitting component parallel connections on the both positive and negative polarity end points of power supply output of connecting circuit on the circuit board, described circuit board is fixed on the bearing rib; Power supply unit in the described housing comprises power storehouse, be embedded in this power storehouse through safety certification, commercially available variable-voltage power supply, the output line of described variable-voltage power supply is through switch and the input that is electrically connected on connecting circuit on the circuit board, and the pin of this variable-voltage power supply leans out the outer surface of housing.Variable-voltage power supply also after the transformation is exported 220 volts civil power access with the low pressure that the people is not produced infringement, control through switch, drive lumination of light emitting diode, wherein the circuit on the circuit board is the connecting circuit of being made up of two leads, and two light emitting diodes are connected in parallel in the two poles of the earth of this connecting circuit output.
The utility model is owing to adopt technique scheme, so, have characteristics safe in utilization, coloury.In addition because variable-voltage power supply adopts commercially available and through the power supply assembly of safety certification, so this kind mini light night needn't carry out safety certification again, product is reliable, cost is low and accepted by market easily.
Description of drawings
Fig. 1 is that the master of the utility model light emitting diode mini light night looks cross-sectional schematic.
The specific embodiment further describes embodiment of the present utility model below in conjunction with accompanying drawing.
As can be known from Fig. 1, this light emitting diode mini light night, comprise housing 1 that two parts fasten to form internal cavities with and inner bearing rib 11, power supply unit 2 and the Lighting Division 3 that is provided with, the light inlet window 5 that also is provided with switch 4 on this housing 1 and Lighting Division 3 light are appeared, described switch 4 control power supply units 2 are switched on or switched off with Lighting Division 3; Described Lighting Division 3 comprises the light-emitting component 31 of at least two colorful light-emitting diodes and the circuit board 32 of light-emitting component 31 is installed, be connected in after these two light-emitting component 31 parallel connections on the both positive and negative polarity end points of power supply output of connecting circuit on the circuit board 32, described circuit board 32 is fixed on the bearing rib 11; Power supply unit 2 in the described housing 1 comprises power storehouse 21, be embedded in this power storehouse 21 through safety certification, commercially available variable-voltage power supply 22, the output line 221 of described variable-voltage power supply 22 is through switch 4 and the input that is electrically connected on connecting circuit on the circuit board 32, and the pin 222 of this variable-voltage power supply 22 leans out the outer surface of housing 1.Variable-voltage power supply 22 also after the transformation is exported 220 volts civil power access with the low pressure that the people is not produced infringement, through the control of switch 4, the light-emitting component 31 that drives light emitting diode is luminous.
As can be known from Fig. 1, described light inlet window 5 is inserted with optical fiber jewelry 6 for connecting the open-work 51 of housing 1 in the described open-work 51.After the energising, the light-emitting component 31 of colorful light-emitting diode sends the light of different colours, and this light is radiated at the root of optical fiber jewelry 6 by open-work 51, is delivered to the termination of optical fiber again through the optical fiber on the optical fiber jewelry 6, constitutes beautiful luminous body and pattern.
As can be known from Fig. 1, the size of described power storehouse 21 institute's perforate 12 on housing 1 contains the back side size of pin less than variable-voltage power supply 22; Two parts of housing 1 fasten moulding, and the checkpost in hole 12 is on the back side of variable-voltage power supply 22, and variable-voltage power supply 22 is fixed by hole 12.
