A novel LED lamp bulb mainly comprises a lamp cap, a lamp bulb top housing, a circuit board for driving a power supply, a spherical reflecting shade and a lamp shade. The lamp cap and the lamp bulb top housing are connected integrally in a compressed and joint manner, and the power supply is led in through connecting a positive electric wire, a negative electric wire and the circuit board for driving the power supply by the lamp cap. The spherical reflecting shade comprises a spherical reflecting cup and a luminescnet set formed through connecting a plurality of LEDs. LED installing ports distributed evenly in a circular manner and in layers between which the angles vary are arranged on the spherical reflecting cup. The LED luminescnet set adopts 'layer' as the unit, and is installed on the LED installing port on the inner side of the spherical reflecting cup. Each layer of the LED luminescnet set connects single LEDs in series through a flexible PCB. The direct current source on the circuit board for driving the power supply is respectively connected with the flexible PCBs, and can light each layer of LED luminescnet set on the spherical reflecting cup after being electrified. Three fixed supports are arranged on the spherical reflecting cup to be inserted in the fixing hole on the back side of the circuit board for driving the power supply. Moreover, the lamp shape and the lamp bulb top housing are connected to fix the circuit board for driving the power supply and the spherical reflecting shade in the middle part.

Description

A kind of New LED bulb

Technical field

The utility model relate to a kind of LED lamp application, relate in particular to the New LED bulb of a kind of LED of use lamp as the bulb in traditional lighting field.

Background technology

So-called LED just is meant the abbreviation of Light Emitting Diode, our light emitting diode of often saying just, this product and use more not nowly just has, and it is applied in our the present actual life and is seen everywhere, and for example the indicator lamp of all kinds on the billboard in roadside, the household electrical appliance and the back lighting on the cell phone keyboard or the like all are to have adopted LED as light source.LED lamp backlight uses DC voltage usually, is applied to small-sized monochrome display usually, such as phone, remote controller, micro-wave oven, air-conditioning, instrument and meter, stereo audio equipment etc.The LED-backlit source is a spot light.At present, the light-emitting area of being seen LED bulb is that single led in one plane the arrangement forms on the market, forms a luminous collection of LED.Because the lighting angle of monomer LED itself is narrower, though the light spotlight effect that the luminous collection of LED is sent when planar alignment is very good, but the area of its high light is but very little, usually have only the luminous collection area of LED about 5 times, and the uneven illumination in its range of exposures is even, hot spot clearly can occur.Owing to be subjected to the restriction of conventional lamp installing space, the luminous collection area of arranging the LED bulb that forms with planar fashion can not be excessive, makes it be difficult to accomplish the effect of high brightness.Therefore arrange the LED bulb that forms with planar fashion and can not solve the narrow and low shortcoming of brightness of irradiated area.Therefore it is not suitable for being applied to illumination, also can't replace the traditional lighting bulb.

The utility model content

The technical problems to be solved in the utility model is: a kind of New LED bulb is provided, and it has overcome, and the irradiated area of LED bulb of existing planar alignment is narrow, brightness is low, the uneven shortcoming of luminosity.It is a kind of New LED bulb of sphere that the utility model provides a kind of reflective surface, and this bulb structure irradiated area is big, illumination utilization rate height, luminous evenly, brightness is high, is not subjected to the restriction in lamp installation space, exquisite appearance.

In order to solve the problems of the technologies described above, the utility model proposes following technical scheme: a kind of New LED bulb, it mainly is made up of lamp holder, bulb upper casing, power driving circuit plate, sphere reflection shield and lampshade.

This lamp holder and bulb upper casing fuse in the crimping mode, and the introducing of power supply is to be formed by connecting by two both positive and negative polarity electric wires and power driving circuit plate by lamp holder.This sphere reflection shield is made up of the luminous collection that some LED are formed by connecting a sphere reflector and several.To have with the circle on this sphere reflector be that planning is arranged in a uniform, is structure with the level, layer with layer between the different LED installing port of angle.The luminous collection of LED is unit with the layer, is installed on the LED installing port of sphere reflector inboard.Each layer of the luminous collection of LED gets up single led polyphone by flexible PCB.Dc source on the power driving circuit plate links to each other with each layer flexible PCB respectively, and energising just can be lighted the luminous collection of each layer LED on the sphere reflector.This sphere glow cup is provided with three fixing feet, to insert on the back side fixing hole on the power driving circuit plate.This lampshade and bulb upper casing join and are clipped in the middle power driving circuit plate, sphere reflection shield fixing.

The beneficial effects of the utility model are: utilize sphere reflection shield sphere and reflection action, the luminous collection of LED just can be luminous to each different angles.It is big to reach irradiated area, illumination utilization rate height, luminous evenly, light is soft, is not subjected to the restriction in lamp installation space, the purpose of exquisite appearance.

The specific embodiment

See also Fig. 1 to Fig. 2, a kind of New LED bulb, it mainly is made up of lamp holder 1, bulb upper casing 2, power driving circuit plate 3, sphere reflection shield 4 and lampshade 5.

This lamp holder 1 fuses in the crimping mode with bulb upper casing 2, and the introducing of power supply is to be formed by connecting by two both positive and negative polarity electric wires and power driving circuit plate 3 by lamp holder.

This sphere reflection shield 4 is made up of the luminous collection 41 that some LED are formed by connecting a sphere reflector 42 and several, and this sphere reflection shield is a sphere formula illuminator that multi-angle is luminous, and its volume is a basis to the requirement definition of bulb brightness.

This sphere reflector 42 is a kind ofly to form with the plastic raw materials manufacturing, have on the sphere reflector 42 with the circle is that planning is arranged in a uniform, it with the level structure, the layer with layer between the different LED installing port 43 of angle, the size of LED installing port 43 defines according to single led size, and LED installing port 43 has fixing single led groove position (figure does not show) in sphere reflector 42 inboards.

The luminous collection of LED 41 is a unit with the layer, is installed on the LED installing port 43 of sphere reflector 42 inboards.Each layer of the luminous collection 41 of LED gets up single led polyphone by flexible PCB.
