Abstract
The utility model relates to a luminescent diode cup lamp mainly comprising a lamp cup, a circuit board and at least one luminescent diode, wherein, the lamp cup is a lamp shade which can condense light; the bottom of the lamp shade is convexly provided with two inserting terminals which can be directly connected with a lamp holder or a power supply; the circuit board is arranged in the lamp cup; a rectifying circuit and a pressure reducing circuit are arranged on the circuit board; a power supply line of the circuit board is connected with the inserting terminals of the lamp cup; the luminous diode is a luminous body arranged on the circuit board; the luminous diode emits light after energized, a light source is projected to a certain direction through the lamp cup. Because the luminous diode has the advantage of low power consuming, the effect of power supply saving is achieved.
Description
The utility model relates to a kind of light fixture, refers to a kind of LED Light Cup especially.
In the past, the light source kind of manually making was various, and common light source has: incandescent lamp bulb, gas discharge tube and fluorescent lamp etc., and wherein the longest with the useful life of fluorescent lamp, save power supply the most; But, the equal active development improvement of researcher, the high light fixture of a kind of luminous efficiency is developed in expectation, to adapt to the needed luminosity in some areas, so often an electric power loop and a variable resistor are linked, send different lightnesses with the control light fixture, but often need repeatedly adjust and watch, make the user feel trouble, and otherwise the time change the bulb that is burnt.
The purpose of this utility model provides a kind of low power consumption, brightness height, saves the LED Light Cup of power supply.
For achieving the above object, the utility model adopts following design: a kind of LED Light Cup mainly includes a Lamp cup, and is placed in Lamp cup interior circuit board and at least one light-emitting diode that is arranged on the circuit board; This circuit board is provided with two resistance, two Zener diodes, a fuse and a rectifier bridge, the power input of this rectifier bridge is parallel with the AC power cord of a resistance and two tool opposed polarities respectively, and in a fuse and another resistance of connecting between resistance and AC power cord, the power output end of rectifier bridge is parallel with two Zener diodes and at least one light-emitting diode of a serial connection and opposition; But described Lamp cup is the lampshade of an optically focused, and convexes with two inserting terminals bottom this Lamp cup, and one-body molded; Extending two power lines on the described circuit board links to each other with two inserting terminals of described Lamp cup;
Described Lamp cup is a closed lampshade;
Described Lamp cup bottom is the light bulb head of spiral tool contact site.
Because the light-emitting diode that the utility model employing power consumption is low, brightness is high, save power supply only need hang down wattage and just can produce higher brightness as luminous element; And its average life, generally the long service life of bulb was 20 times up to tens thousand of hours.On circuit board, two power lines on the hand off circuit plate again make it be connected with two inserting terminals on the Lamp cup, again with integral forming method, circuit board are fixedly arranged in the Lamp cup subsequently with the direct solid welding of several light-emitting diodes.
Further specify below in conjunction with accompanying drawing.
Fig. 1 is the utility model LED Light Cup stereogram.
Fig. 2 is the another LED Light Cup stereogram of the utility model.
Fig. 3 is the utility model one preferred circuit figure.
Shown in Figure 1, the utility model provides a kind of LED Light Cup, and it comprises a Lamp cup 10, a circuit board 20 and at least one light-emitting diode 30, and wherein, but Lamp cup 10 is the lampshade of an optically focused, and the bottom of this Lamp cup 10 convexes with two inserting terminals 11; Circuit board 20 is for being placed in the circuit layout plate of Lamp cup 10 inside, and this circuit board 20 is provided with rectification and reduction voltage circuit, and extends two inserting terminals, 11 bindings of two power lines 21 and Lamp cup 1O on this circuit board 20; Light-emitting diode 30 after these light-emitting diode 30 energisings, can produce the light with a kind of color or different colours for being arranged at the luminous element on the circuit board 20.
After aforementioned light-emitting diode 30 is welded on the circuit board 20, can be with two inserting terminals, 11 welding on two power lines on the circuit board 20 21 and the Lamp cup 10, subsequently again with integral forming method, circuit board 20 set firmly be coated in the Lamp cup 10, and allow two inserting terminals 11 directly be connected with lamp socket or power supply (not shown); After two-terminal 11 energisings, circuit board 20 makes light-emitting diode 30 luminous, sees through the guiding of Lamp cup 10, and makes light source invest a distant place.
Please consult shown in Figure 2ly again, be the stereogram of the another LED Light Cup of the utility model, with last figure relatively, its difference only is that original two inserting terminals 11 in Lamp cup 10 bottoms change to the light bulb head 11A of spiral tool contact site, and is the same with general bulb; In addition, the mode that Lamp cup 10 vacuumizes with air blowing can be made the globe holder (not shown) of closed, just as the moulding similar with general bulb.
Fig. 3 is the preferred circuit figure of the utility model circuit board 20.As shown in the figure, circuit board 20 is provided with two resistance 22,23, two Zener diodes 24, a fuse 25, a rectifier bridge 26 and light-emitting diode 30.The power input of this rectifier bridge 26 is parallel with the AC power cord 21 of a resistance 23 and two tool opposed polarities; And in 21 of resistance 23 and AC power cord connect a fuse 25 and another resistance 22; The power output end of rectifier bridge 26 is parallel with two Zener diodes 24 and at least one light-emitting diode 30 of a series connection and opposition.After two power line energisings, alternating current produces direct current through rectifier bridge 26 rectifications and provides power supply for all light-emitting diodes 30, so that light-emitting diode 30 produces light source; Again, so the direction opposition that two Zener diodes 24 are provided with is can be with excessive current lead-through with protection light-emitting diode 30; Resistance 22 can be adjusted reduction voltage; Another resistance 23 can protect rectifier bridge 26 not burnt.
The above is the utility model preferred embodiment only, is not so inflexible limit the utility model claim, so the structure that all utilization the utility model specifications and the equivalence of graphic content change all belongs within the utility model protection range.
