Technical field

The utility model relates to lighting field, particularly a kind of LED bulb lamp.

Background technology

LED bulb lamp outward appearance adopts bulb profile (spherical), and internal light source adopts LED light source, and it relies on energy-saving and environmental protection, without plurality of advantages such as stroboscopic, long service life, is widely used in various lighting fields.

Because the luminous intensity of single led chip is limited, in order to obtain required brightness of illumination, need to be at the inner integrated a plurality of LED chips of LED bulb lamp, but will certainly cause like this LED bulb lamp internal calorific power large.Given this, how to promote the radiating effect of LED bulb lamp, more receive people's concern.

Existing LED bulb lamp generally includes glass cell-shell, lamp socket, lamp holder and LED light source, its radiating mode is mainly: the heat that LED light source produces is delivered on glass cell-shell by lamp socket in heat conducting mode, glass cell-shell with the mode of thermal convection current by dissipation of heat in air.Different from the material that glass cell-shell adopts due to lamp socket, need to connect by connected modes such as splicing, between the two, there is certain thermal resistance, heat can not be transmitted on glass cell-shell in time, thereby cause LED bulb lamp integral heat sink weak effect.In addition, glass cell-shell is easily broken, causes LED bulb lamp to reduce service life, and after the fragmentation of glass cell-shell, LED light source is directly exposed to the external world, and still can, in energising duty, exist certain potential safety hazard.

Utility model content

The purpose of this utility model is to provide that a kind of good heat dissipation effect, intensity are high, long service life, LED bulb lamp that security is good.

For achieving the above object, the utility model is by the following technical solutions:

A high-heat-dispersion LED bulb lamp, comprising:

Devitrified glass cell-shell, its spherical in shape and one end has opening;

Devitrified glass lamp socket, itself and described devitrified glass cell-shell are sintered to one;

Lamp holder, it is connected with described devitrified glass lamp socket;

FPC circuit board, it fits on described devitrified glass lamp socket by heat-conducting glue, and is electrically connected with described lamp holder;

One group of LED chip, it is welded on FPC circuit board.

Preferably, described devitrified glass lamp socket is class conical shell, and its one end has opening, and the openend of described devitrified glass lamp socket is connected with the openend sintering of described devitrified glass cell-shell.

Preferably, described LED chip is vertical flip LED chips, is coated with fluorescent material on it.

Adopt after technique scheme, the utility model is compared with background technology, and tool has the following advantages:

1. devitrified glass cell-shell of the present utility model and devitrified glass lamp socket are sintered to integrative-structure, have reduced thermal resistance, and the heat that LED chip produces can be delivered to rapidly whole devitrified glass cell-shell by devitrified glass lamp socket, is conducive to distributing of heat.

2. adopt cell-shell and the lamp socket that high strength micro-crystalline glass material is made to be difficult for fragmentation, improved bulk strength and the service life of LED bubble lamp, also improved the security of LED bubble lamp simultaneously.

3. the utility model becomes class conical shell by devitrified glass lamp socket designs, increased itself and devitrified glass cell-shell over against angle and area, LED chip can carry out multi-angle installation, is convenient to increase light angle.

4.LED chip adopts vertical flip LED chips, can form effective thermoelectricity separated, and resistance to large-drive-current, has significantly promoted radiating efficiency and luminous efficiency.
