Description

Extensive angle LED bulb lamp

[technical field]

The utility model relates to the LED technical field, particularly a kind of extensive angle LED bulb lamp.

[background technology]

The lighting of convention comprises incandescent lamp, fluorescent lamp, Metal halogen lamp, LED lamp etc., wherein, and incandescent lamp, fluorescent lamp low price; Performance can satisfy the demand of general domestic consumer, deeply Chinese rural area etc., but its life-span of incandescent lamp is short; Electro-optical efficiency is low, contains infra-red radiation and is prone to broken; Fluorescent lamp contains infrared ray and ultraviolet ray, heavy metal Hg, and not environmental protection has limitation service life; And the Metal halogen lamp that occurs in succession can reach 100LM for every watt, and the colour developing row is higher than 90, but 1000 hours its service life; Along with further developing of lighting technical field, led light source because of have use low-tension supply, power consumption less, strong, the stability height of applicability, response time weak point, environmentally safe, advantage such as multicolor luminous, become main flow lighting source of new generation; LED has replaced existing incandescent lamp, fluorescent lamp etc. gradually as the LED fluorescent tube of lighting source, LED bulb lamp etc.; Yet LED bulb lamp of the prior art, its LED luminescence chip are fixedly installed on the installing plate in the lamp housing; Its lighting angle is less; Only have about 120 °, the dark space around the light fixture top is bigger, has certain defective.

[summary of the invention]

The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of lighting angle big, the extensive angle LED bulb lamp of no dark space around the light fixture top.

The purpose of the utility model is to realize like this: it comprises lamp holder, heat radiation aluminium body, LED luminescence chip, lampshade; Said lamp holder lower end is connected with light source bracket; Said light source bracket is provided with the PCB substrate, and its improvement is: said light source bracket becomes the prismatic column structure, and the cross section of said prismatic column structure is regular polygon; The parallel respectively PCB substrate that is equipped with in each side of place light source bracket; The PCB substrate is provided with a slice LED luminescence chip at least, and the lower end surface of light source bracket is equipped with a PCB substrate, and the PCB substrate is provided with a slice LED luminescence chip at least.

In the said structure, said regular polygon is a regular hexagon, on six sides of light source bracket, is separately installed with a PCB substrate, and adjacent in twos PCB substrate is mutually 120 °.

In the said structure, the PCB substrate of the lower end surface of said light source bracket is provided with three LED luminescence chips that are mutually 120 °.

The utility model beneficial effect is: the utility model is through being designed to light source bracket the prismatic column structure, and the lower end surface that PCB substrate and light source bracket are set respectively in each face of column structure is equipped with a PCB substrate, so; Make the lighting angle of LED bulb lamp enlarge, reduced the dark space on every side of light fixture top, further; Light source bracket is the regular hexagon column, and six PCB substrates are installed on each surface of light source bracket, and adjacent in twos PCB substrate is mutually 120 °; By this; Make the lighting angle maximization of LED bulb lamp, eliminated the light fixture top around the dark space, the illumination effect of this LED bulb lamp is more near the illumination effect of fluorescent lamp; In addition, it is simple in structure, is convenient to produce in batches, and is practical.

[specific embodiment]

Below in conjunction with accompanying drawing and the specific embodiment the utility model is done and to be further described:

Referring to figs. 1 through shown in Figure 3, the utility model has disclosed a kind of extensive angle LED bulb lamp, and it comprises lamp holder 1, heat radiation aluminium body 2, LED luminescence chip 3, lampshade 4; Wherein, heat radiation aluminium body 2 is fixed in the lower end of lamp holder 1, said lamp holder lower end heat radiation aluminium body 2 be internally connected with light source bracket 5; Light source bracket 5 is provided with PCB substrate 6; 5 one-tenth prismatic column structures of said light source bracket, the cross section of said prismatic column structure is regular polygon, and promptly light source bracket 5 is the prismatic cylinder of regular polygon for its cross section; Include the side that equates with polygon limit number; The parallel respectively PCB substrate 6 that is equipped with in each side of light source bracket 5, PCB substrate 6 is provided with a slice LED luminescence chip 3 at least, and the lower end surface of light source bracket 5 also is equipped with a PCB substrate 6; PCB substrate 6 is provided with a slice LED luminescence chip 3 at least, and the concrete needs of how many bases of its mounted LEDs luminescence chip 3 numbers are set.

With reference to shown in Figure 3, preferable, said regular polygon is a regular hexagon, and promptly the cross section of light source bracket 5 is regular hexagon, on 5 six sides of light source bracket, a PCB substrate 6 is installed, and adjacent in twos PCB substrate 6 is mutually 120 °; Make its lighting angle maximization, the PCB substrate 6 of the lower end surface of said light source bracket 5 is provided with three LED luminescence chips 3 that are mutually 120 °.

To sum up, the utility model is through being designed to the prismatic column structure with light source bracket 5, and the lower end surface that PCB substrate 6 and light source bracket 5 are set respectively in each face of column structure is equipped with a PCB substrate 6; So, make the lighting angle of LED bulb lamp enlarge, reduced the dark space on every side of light fixture top; Further, light source bracket 5 is the regular hexagon column, on light source bracket 5 each surface, six PCB substrates 6 is installed; Adjacent in twos PCB substrate 6 is mutually 120 °, by this, makes the lighting angle of LED bulb lamp maximize; Eliminated the light fixture top around the dark space, the illumination effect of this LED bulb lamp is more near the illumination effect of fluorescent lamp; In addition, it is simple in structure, is convenient to produce in batches, and is practical.
