Abstract

The utility model discloses an LED bulb which comprises a lamp holder and a lamp housing clamped in the lamp holder, wherein the lamp holder includes a lamp holder housing and a lamp holder base located in the lamp holder housing. A power supply and a PCB circuit board are embedded in the lamp holder seat, wherein the power supply is electrically connected with the PCB circuit board, and an LED lighting column is electrically connected on the PCB circuit board. A tube is sleeved over the LED lighting column which comprises a glass substrate and at least one LED chip arranged on the glass substrate. The heat radiation performance of the LED bulb is improved, and a heat radiation device of a conventional bulb is eliminated. The tube better gathers light source of the LED lighting column, thereby improving utilization rate of light source, achieving omnibearing and multi-angle lighting, and improving the luminance the LED bulb.

Description

Technical field

The utility model relates to a kind of bulb, relates in particular to a kind of LED bulb.

Background technology

At present, due to LED(Light Emitting Diode, light emitting diode) there is the features such as long service life, energy consumption is low, the saving energy is remarkable, therefore, LED has been widely used in daily life as light source, as LED lightings such as cup lamp, shot-light, auto lamp, LED bulbs.

Existing LED bulb generally comprises lamp holder, be arranged on the lamp housing at lamp holder top, be positioned at the power supply of lamp holder, in lamp housing, be provided with LED Column being luminous, LED Column being luminous is electrically connected with the power supply in lamp holder, in the time of LED Column being luminous electrified light emitting, its light sending can see through lamp housing and shine out, the object that reaches illumination or decorate, simultaneously, for bulb is better dispelled the heat, it is also often all provided with heat abstractor, and the position that arranges of heat abstractor has stopped the luminous of bulb to a certain extent.

And the LED Column being luminous of LED bulb is the direct packaged LED of welding on ceramic substrate mostly in prior art, because ceramic substrate is opaque, cause LED Column being luminous can only one direction luminous, light coverage is less, and general maximum can only reach 180 degree.

Utility model content

The object of the utility model embodiment is to overcome problems of the prior art, and a kind of LED bulb is provided, and its good heat dissipation effect can accomplish that comprehensive multi-angle is luminous.

For achieving the above object, the utility model adopts following design, a kind of LED bulb, comprise lamp holder and lamp housing, lamp housing is fastened on lamp holder, described lamp holder comprises lamp shell and is located at the bulb socket in lamp shell, in described bulb socket, be embedded with power supply and PCB wiring board, described power supply is electrically connected with PCB wiring board, on described PCB wiring board, be electrically connected to the LED Column being luminous of few, wherein LED Column being luminous outside is also arranged with fluorescent tube, and described LED Column being luminous comprises glass substrate and is located on glass substrate the LED chip of at least one.

Further, described fluorescent tube is fixed on the fixed structure at bulb socket top.

Preferably, described fixed structure is a hollow trench structure, and the diameter of described trench structure is greater than the diameter of fluorescent tube, and described fluorescent tube plugs and is fixed in trench structure.

Preferably, on described PCB wiring board, be electrically connected with many LED Column being luminous.

Preferably, on the inwall of described fluorescent tube, be coated with phosphor powder layer.

Preferably, described LED chip is provided with phosphor powder layer.

Preferably, described LED chip is high-voltage LED chip.

Preferably, described lamp housing is transparent lamp case.

The utility model adopts above design, by sheathed fluorescent tube on LED Column being luminous, the heat of LED Column being luminous can better be distributed by fluorescent tube, improve its heat-sinking capability, save the heat dissipation equipment in existing bulb, and fluorescent tube can better converge the light source of LED Column being luminous, improve the utilization rate of light source; By LED chip is designed on glass substrate, better accomplish the luminous of comprehensive multi-angle, improve the luminance of LED bulb.
