Abstract

The utility model discloses a light emitting diode (LED) bulb with a high lighting effect and a wide angle. The LED bulb comprises a basic shell, a lamp head positioned at the bottom of the basic shell, a constant current power supply (comprising parts such as connectors and wires) arranged in the basic shell, a cover plate covering the top of the basic shell, a specially-formed cubical heat radiating column fixed above the cover plate, and a lamp shade which is used for accommodating the heat radiating column and connected with the basic shell, wherein the bottom surface of the heat radiating column is arranged on the cover plate, printed circuit boards (PCB) are adhered to other surfaces, and a plurality of LED chips are distributed and welded on each PCB board. According to a special structure and heat radiating design, the lighting angle of the LED bulb is more than 270 degrees under the condition of using a transparent lamp shade, a heat dispersion effect is good, and the lighting effect of whole lamp is improved, so the LED bulb is specially used for a crystal lamp, and an effect is remarkable.

Description

High light efficiency large-angle LED bulb

Technical field

the utility model relates to a kind of LED lighting device.

Background technology

The LED bulb that sell in the market is owing to the directed characteristics of luminescence of led chip lamp pearl, if use Transparent lamp shade, lighting angle has only about the 15O degree, is difficult to realize enlarging lighting angle.But a lot of light fixtures need expand the lighting angle of light emitting source, and traditional method is to adopt the method for coating atomizing to carry out the light diffusion, thereby reaches the purpose that increases rising angle, but adopts the method can cause light loss, descends thereby whole light is imitated.

Summary of the invention

in order to solve the problems of the prior art, the purpose of the utility model provides the big and higher high light efficiency large-angle LED bulb of light extraction efficiency of a kind of lighting angle.

in order to achieve the above object; The utility model provides a kind of high light efficiency large-angle LED bulb; It comprises basic shell, be positioned at described basic shell bottom lamp holder, be installed on the inner constant-current supply (containing parts such as connector, lead) of described basic shell, be covered in described basic shell top cover plate, be fixed in the diffuser that is cubical special heat radiation column, accommodates described heat radiation column and be connected of described cover plate top with described basic shell facies; Wherein, The bottom surface of described heat radiation column is installed on the described cover plate, and all the other faces all post pcb board, and distributing on the every pcb board is welded with several led chips.

preferably scribble heat-conductive coating on the binding face between described pcb board and the heat radiation column.

preferably, each lighting angle with pcb board of led chip is 125 degree, and is luminous to realize omnibearing stereo.

preferably, described diffuser is processed by glass or PC material.

Preferably, described cover plate is processed by reflectorized material , and cover plate plays attractive in appearance and reflective effect.

preferably, the outside of described basic shell is formed with a plurality of fin.

are owing to adopted technique scheme; Make the utility model compared with prior art have following beneficial effect: through particular structural and heat dissipation design; Under the situation that adopts Transparent lamp shade, realize LED bulb lighting angle greater than 270 degree, and heat radiation is good, improves whole light and imitate; Particularly be used on the crystal lamp, remarkably productive.

The specific embodiment

Set forth the preferred embodiment of the utility model below in conjunction with accompanying drawing in detail ; Thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.

are shown in accompanying drawing 3; A kind of high light efficiency large-angle LED bulb; It comprises basic shell 5, be positioned at the lamp holder 6 of basic shell 5 bottoms, be installed on the inner constant-current supply of basic shell 5, be covered in the cover plate 2 at basic shell 5 tops, the diffuser 7 that is fixed in being of cover plate 2 tops cubical heat radiation column 1, accommodates heat radiation column 1 and be connected with basic shell 5; The outside of base shell 5 is formed with a plurality of fin, and diffuser 7 is processed by glass or PC material.

referring to accompanying drawing 1 and accompanying drawing 2, heat radiation column 1 is cube structure, and the underrun screw of heat radiation column 1 is fixed on the cover plate 2, and all the other 5 faces all post pcb board 3, and distributing on the every pcb board is welded with several led chips 4; Wherein, Heat radiation column 1 is processed by the material of good heat dispersion performance such as aluminium; Scribble heat-conductive coating to strengthen heat-conducting effect on the binding face between pcb board 3 and the heat radiation column 1; Led chip in the present embodiment adopts the high-brightness white-light LED chip light source, and each lighting angle with pcb board 3 of led chip 4 is that 125 degree are luminous to realize omnibearing stereo.Cover plate 2 is processed to play attractive in appearance and reflective effect by reflectorized material.

are not difficult to find out that through above-mentioned embodiment the utility model is the big and higher high light efficiency large-angle LED bulb of light extraction efficiency of a kind of lighting angle.

above embodiment that combines specifies the utility model; Only for the technical conceive and the characteristics of the utility model are described; Its purpose is to let the people that is familiar with this technology understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this, all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
