Abstract

The utility model discloses a luminous diode lamp bulb. The osram lamp bulb widely used in the past has high power consumption, strong light radiation and large heat quantity. The LED lamp which is usually used as a display lamp also has the defects of small luminous angle and high request to the stability of the voltage. The luminous diode lamp bulb of the utility model is provided with a voltage reduction rectifier in a lamp cap, and the upper end of the voltage reduction rectifier is provided with an insulating board which is provided with one or a plurality of LED lamps. The inner part of a lamp bulb casing and the lamp cap are connected with a reflecting device. The upper part of the reflecting device is a transparent body. Thereby, the luminous diode lamp bulb has the advantages of low power consumption, electric energy saving, cold body lighting and long service life, and does not disturb the system power supply. The system is unexpectedly changed without obvious blinking effect, and the luminous diode lamp bulb can realize omnidirectional lighting effect. The luminous diode lamp bulb is widely suitable for being used for indoor bathrooms and walkways and serves as various indicating lamps.

Description

Light emitting diode bulb

Technical field

The utility model relates to a kind of emitting bulb, particularly a kind of LED light emitting diode bulb.

Background technology

Illumination of generally using on the market now and decoration emitting bulb, moulding is varied and riotous with colour, but with regard to its structure, normally by lamp holder, luminous tungsten filament and the glass shell after vacuumizing form, thereby its power consumption height, light radiation is strong, and caloric value is big, unsafe high-temperature effect is arranged, and service life is low.And at present mainly be used to do the LED LED light lamp of display lamp, and also there is the luminous top area that accumulates in, the visual angle is little, the deficiency that lateral luminance is faint, and to the stability requirement height of voltage, the accident of system voltage changes the flicker that also can cause bulb.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provide a kind of with the LED lamp as light emitting source, be furnished with refraction and scattered light device, be suitable for the wide emitting bulb of voltage range.

The technical scheme that its technical problem that solves the utility model adopts is: light emitting diode bulb, comprise lamp holder, the bulb shell that is connected with lamp holder is equipped with buck rectifier in lamp holder, there is insulation board the upper end of buck rectifier, and one or more LED lamps are housed on the insulation board; In the bulb shell, connect reflection unit on the lamp holder, its axis direction of the lower end edge of reflection unit has a hole; Described reflection unit top is the transparent body.

The beneficial effects of the utility model are: light emitting diode bulb of the present utility model adopts the LED lamp as light emitting source, and in lamp holder, install buck rectifier additional, thereby low in energy consumption, saves energy, cold body is luminous, the life-span is long advantage have been had both, and can not produce any interference to system power supply, the unexpected variation of system do not have obvious flicker effect yet; Install reflection unit additional in bulb inside, and reflection unit top is the transparent body, therefore can reaches the effect of comprehensive illumination.

Description of drawings

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

Fig. 1 is a broken away view of the present utility model;

Fig. 2 is a front view of the present utility model;

Fig. 3 is that the LED lamp of a kind of embodiment of the present utility model amplifies layout drawing.

The specific embodiment

With reference to Fig. 1, Fig. 2, light emitting diode bulb of the present utility model, comprise lamp holder 9, the electrode points 10 of lamp holder 9 connects with the power supply input point of buck rectifier 7 respectively by lead 8, one insulation board 6 is arranged in the upper end of buck rectifier 7, one corresponding with it eyeglass 5 is arranged on the insulation board, eyeglass 5 can adopt materials such as pressing the upright material of gram to make, insulation board 6 bonds together with pressing the upright eyeglass 5 of gram, LED lamp 4 is installed on the connector of pressing upright eyeglass 5 of gram and insulation board 6, a plurality of LED lamps also are linked together, power supply output point by lead and buck rectifier 7 links, the connector integral installation of buck rectifier 7 and upright eyeglass 5 of pressure gram and insulation board 6 utilizes insulating cement that bulb shell 1 and lamp holder 9 are fixed shell 1 useable glass resin in the lamp holder 9 of bulb, clear PE, PC, perspex systems such as ABS become.Behind external power supply process buck rectifier 7 step-down rectifiers, for the luminous use of one or more LED lamps.Based on the LED light emitting diode is cold light source, eliminated because high heat generation circuit breaks and the misgivings of lamp body moulding or external form packing, thereby taken into account low in energy consumption, saves energy, safe and reliable, the life-span long, the advantage of environmental protection, it is wide to be suitable for voltage range, and can not produce any interference to system power supply, the unexpected variation of system do not have obvious flicker effect yet.

With reference to Fig. 3, in the bulb shell 1, pressing on the upright eyeglass 5 of gram has a groove 11, and reflection unit 3 is installed in the groove 11.Reflection unit 3 can be made with transparent material, and as glass, perspex body, press the upright section bar of gram etc., outer surface plates with the good material of reflective function, as chromium etc.; LED lamp 4 is installed in and leans on reflection unit 3 outsides on the eyeglass, thereby can make the light source reflection, reaches the function of lateral emitting; Reflection unit 3 tops are a rhombus transparent body 2, reflection unit 3 has a hole along its axis direction, the LED bulb is installed in the hole, the LED lamp source is done regional scattering by the rhombus transparent body 2, thereby cause comprehensive spot light, certainly transparent body shape is not limited to rhombus, also can be other shape.
