Abstract

The utility model discloses an LED lamp. The LED lamp comprises a lamp holder (1); a driving circuit is arranged in the lamp holder (1); a lamp head (2) is arranged at one end of the lamp holder (1); a radiator (3) is arranged at the other end of the lamp holder (1); four LED base plates (5) are vertically arranged on the radiator (3); a transparent lamp shade (4) covering the four LED base plates (5) is arranged at the end of the lamp holder (1); the LED base plates (5) form a square; a plurality of LED chips (6) are arranged on the outer side surface of each LED base plate (5); and the driving circuit is electrically connected with the lamp head (2) and the LED chips (6). The four LED base plates are connected circularly to form the light emitting surfaces of the square, the included angle of each light emitting surface is 90 degrees, which is smaller than the 120 degree light emitting angle of a patch LED chip, therefore, the illumination angle of a luminous body formed by the four light emitting surfaces can exceed 360 degrees, all the illumination scope is covered, and the LED lamp has no illumination blind zone. Moreover, as the radiator is adopted, heat dissipation is good.

Description

A kind of LED bulb
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.The 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 90 ℃, 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 360 ℃ of irradiations, good heat dissipation.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of LED bulb, 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 four LED substrates, this end at lamp socket is provided with the Transparent lamp shade that covers four LED substrates, described four LED substrates surround square, 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.
Led chip on described each LED substrate is formed series circuit, and the led chip of four LED substrates is formed parallel circuit.
Owing to adopted above-mentioned structure, four LED substrates encompass the light-emitting area of square, the angle of each light-emitting area is 90 ℃, 120 ℃ lighting angle less than the paster LED chip, only need to adopt lighting angle greater than 90 ℃ 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; 49 ℃ of LED bulb hull-skin temperatures 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 LED bulb;
Fig. 2 is the stereogram after the LED bulb is removed lampshade.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of LED bulb 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 stands and is provided with four LED substrates 5.Be provided with radiator 3 between the bottom of described lamp socket 1 and LED substrate 5.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 four 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 four LED substrates 5 surround square, and the lateral surface of each piece LED substrate 5 is provided with several led chips 6.Four LED substrates 5 surround square 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 four 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, four LED substrates 5 encompass the light-emitting area of square, and the angle of each light-emitting area is 90 ℃, adopt lighting angle for can realize 360 ℃ of irradiations greater than 90 ℃ of led chips 6, covered all ranges of exposures, made the LED bulb 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.
