Description

LED bulb

technical field:

The utility model relates to field of illumination lamp technology, refers in particular to a kind of LED bulb.

background technology:

LED is a kind of light emitting semiconductor device, is used as widely indicator lamp, display screen etc.White light LEDs be described as replace fluorescent lamps and incandescent lamp the 4th generation lighting source.LED has changed the principle that incandescent lamp tungsten filament is luminous and fluorescent lamp tricolor powder is luminous, utilizes electroluminescence, has advantages of that light efficiency is high, radiationless, the life-span long, low-power consumption and environmental protection.A kind of traditional approach that forms white light LEDs is that blue light or ultraviolet chip excite the fluorescent material being attached to above chip, and the light stimulus fluorescent material that chip sends under electric drive produces the visible ray of other wave band, and each several part colour mixture forms white light.Along with the continuous expansion of LED application, also more and more higher to the luminous efficiency requirement of LED encapsulation, and luminous efficiency is the most important parameter that determines LED encapsulation.

Existing LED light fixture, its LED fluorescent tube is general adopts a some formation central point luminous, and due to structure, irradiating angle is subject to obtain restriction, the light that makes to irradiate can not be radiated at the angle of 360 degree, generally all in 180 degree, only have flat luminous effect, positive bright and surrounding is dark during this LED lamp lighting, light is inhomogeneous, brightness and illumination visual impression are poor, and being positioned at positive region can be dazzling, and the arrange light hot spot that sends of LED wafer plane is inhomogeneous.

utility model content:

The purpose of this utility model is exactly to provide a kind of arrangement mode by LED chip to become the LED bulb of spatial arrangement, increase rising angle for the deficiency of prior art existence.

To achieve these goals, the technical solution adopted in the utility model is: LED bulb, it includes lamp holder, is arranged on the diffuser at lamp holder top, lamp holder top is provided with and is positioned at the wick holder, power supply of diffuser inside, the some LED lamp plates that are electrically connected to power supply, LED lamp plate is provided with a plurality of LED chips, wick holder is column structure, and some LED lamp plates are uniformly distributed circumferentially in the peripheral side of wick holder.

Described wick holder is multiedge cylinder structure, and each side of multiedge cylinder is equipped with LED lamp plate.

Described wick holder is four prisms cylinder structure, pentagonal prism body structure or hexagonal prism structure.

On described wick holder, offer mounting groove with the position of the corresponding connection of each LED lamp plate, each LED lamp plate engagement connection is in corresponding mounting groove.

Described LED lamp plate is the vertical strip structure arranging.

Described wick holder is hollow structure, and power supply is arranged on wick holder inside.

Described power supply is electrically connected to each LED lamp plate by electric shock sheet.

Described lamp holder is provided with splicing ear, and splicing ear is electrically connected to power supply.

The utility model beneficial effect is: the LED bulb that the utility model provides, it includes lamp holder, be arranged on the diffuser at lamp holder top, lamp holder top is provided with the wick holder that is positioned at diffuser inside, power supply, the some LED lamp plates that are electrically connected to power supply, LED lamp plate is provided with a plurality of LED chips, wick holder is column structure, some LED lamp plates are uniformly distributed circumferentially in the peripheral side of wick holder, make wick holder side surrounding within one week, all be distributed with LED chip, the arrangement mode of LED chip is become to spatial arrangement, can be luminous from all quarter, rising angle can reach 360 degree, increase rising angle, luminous point distributes wide, the light that each LED chip the sends mixing that can well superpose, improve the efficiency of bright dipping, light is even, the region that is positioned at positive and surrounding can be not dazzling, there is good brightness and illumination visual impression, hot spot is even, and the utility model is simple in structure, energy-efficient, comfortable safety, environment friendly and pollution-free.
