The utility model discloses a full-angle illumination LED bulb, which comprises a lamp base (1). A driving circuit is disposed in the lamp base (1), one end of the lamp base (1) is provided with a lamp cap (2) while the other end is provided with a radiator (3), five LED substrates (5) are vertically arranged on the radiator (3), the end of the lamp base (1) is provided with a transparent lampshade (4) capable of covering the five LED substrates (5), the five LED substrates (5) encircle to form a regular pentagon, the outer side surface of each LED substrate (5) is provided with a plurality of LED chips (6), and the driving circuit is electrically connected with the lamp cap (2) and the LED chips (6). The five LED substrates encircle to form regularly pentagonal luminous surfaces, the included angle between each two luminous surface is 72 degrees and is smaller than the luminous angle of 120 degrees of a surface-mounted LED chip, and the illumination angle of a luminous body formed by four luminous surfaces can be larger than 360 degrees, thereby covering all illumination range and avoiding illumination 'blind area' of the full-angle illumination LED bulb. Besides, the full-angle illumination LED bulb is fine in radiation due to the radiator.
Description
Technical field
The utility model belongs to the technical field of lighting, specifically is meant a kind of LED bulb.
Background technology
At present,, can reach 50,000 to 100,000 hours under the ideal state, therefore be widely used in lighting field because led light source has advantages such as energy-saving and environmental protection, longevity.Existing LED bulb generally is directly several LED to be welded on the aluminium base.But LED is a light harvesting, and general LED lighting angle is 72 ℃, 120 ℃ etc., like this, just means that the LED bulb has directionality, the dead angle will inevitably occur throwing light on, is as good as with general LED shot-light.
The utility model content
The purpose of this utility model is to provide a kind of LED bulb of realizing the global illuminating that 360 ℃ of irradiations, good heat dissipation, assembling are firm.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the LED bulb of global illuminating, comprise lamp socket, be provided with drive circuit in the lamp socket, lamp socket one end is provided with lamp holder, and the other end of lamp socket stands and is provided with five LED substrates, this end at lamp socket is provided with the Transparent lamp shade that covers five LED substrates, described five LED substrates surround regular pentagon, and the lateral surface of each piece LED substrate is provided with several led chips, and drive circuit is electrically connected with lamp holder, led chip.
Described radiator is provided with draw-in groove, and the bottom of LED substrate is stuck in the draw-in groove.
Led chip on described each LED substrate is formed series circuit, and the led chip of five LED substrates is formed parallel circuit.
Owing to adopted above-mentioned structure, five LED substrates encompass the light-emitting area of regular pentagon, the angle of each light-emitting area is 72 ℃, 120 ℃ lighting angle less than the paster LED chip, only need to adopt lighting angle greater than 72 ℃ of led chips, the irradiating angle of the illuminator of being made up of 4 light-emitting areas can surpass 360 ℃, cover all ranges of exposures, makes the LED bulb not have irradiation " blind area ".In addition, owing to adopted radiator, heat radiation is good.After tested, the utility model can realize 360 degree irradiations, and general LED bulb irradiation angle is less than 140 ℃ under the condition of 28 ℃ of indoor temperatures; 51 ℃ of the LED bulb hull-skin temperatures of global illuminating are far below LED PN junction temperature.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the stereogram of the LED bulb of global illuminating;
Fig. 2 is the stereogram after the LED bulb of global illuminating is removed lampshade.
The specific embodiment
As shown in Figure 1 and Figure 2, the LED bulb of global illuminating described in the utility model comprises lamp socket 1, is provided with drive circuit in the lamp socket 1, and lamp socket 1 one ends are provided with lamp holder 2, and the other end of lamp socket 1 is provided with radiator 3.Stand on the described radiator 3 and be provided with five LED substrates 5.The set-up mode of LED substrate 5 is to be provided with to be the draw-in groove that pentagon distributes on radiator 3, and the bottom of LED substrate 5 is stuck in the draw-in groove, and assembling is firm like this.Described LED substrate 5 adopts aluminium to make, heat conduction is good, and the heat that can produce LED fast is transmitted on the radiator 3, and radiator 3 is to be made by the high aluminum of thermal conductivity, can go out the heat radiation of LED adstante febre, be the main devices that reduces the LED node temperature.This end at lamp socket 1 is provided with the Transparent lamp shade 4 that covers five LED substrates 5, and lampshade 4 is cylindrical, adopts frosted PC material, and its advantage is and can effectively lowers dazzle, makes light soft, allows the user obtain a comfortable environment.Described five LED substrates 5 surround regular pentagon, and the lateral surface of each piece LED substrate 5 is provided with several led chips 6.Five LED substrates 5 surround regular pentagon and make that each face is luminous evenly and not to produce angular deviation.Described drive circuit is electrically connected with lamp holder 2, led chip 6.Led chip 6 on described each LED substrate 5 is formed series circuit, and the led chip 6 of five LED substrates 5 is formed parallel circuit.Because the entire circuit of led chip 6 is string and combination, it has promptly realized low voltage starting, and the safety coefficient height can not influence the work of whole light fixture again because of the damage of indivedual led chips 6.
During the utility model work, five LED substrates 5 encompass the light-emitting area of regular pentagon, the angle of each light-emitting area is 72 ℃, adopt lighting angle for can realize 360 ℃ of irradiations greater than 72 ℃ of led chips 6, covered all ranges of exposures, made the LED bulb of global illuminating not have irradiation " blind area ".
In a word; though the utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
