The specific embodiment
Describe the embodiment of the invention below with reference to the accompanying drawings in detail, make purpose of the present invention and effect clearer and more definite.
As shown in Figure 1, the structure of LED lamp of the present invention mainly is made up of power taking body 1, reflector 2, light emitting module 3, circuit module 4 and transmissive body.Describe each part below in detail:
One. power taking body 1
In the power taking of 220V civil power, dual mode is arranged, one, adopt the lamp holder of 220 volts incandescent lamps of usual civil power, present general two kinds of screw socket and the sockets that have; Two, by the direct power taking of plug; So the power taking body 1 among the present invention can be the lamp holder or the plug of usual 220 volts of incandescent lamps of civil power.
Two. reflector 2
As shown in Figure 1, reflector is the refractive body of plating reflective membrane, and embodiment has two kinds, if light emitting module 3 is round, then reflector adopts trumpet type; If light emitting module is for being linear pattern, then reflector is trapezoidal.
Three. light emitting module 3
Four. circuit module 4
This module is converted into lower direct current to 220 volts of alternating currents, and driving LED is luminous.Adopt capacitance decompression or transformer step-down, as shown in Figure 2, wherein, figure (a) is the capacitor step-down circuit, wherein R1 is a resistance, R2 is a current-limiting resistance, and C1 is an electric capacity, and U1 is the bridge heap, D1～D9 is LED, wherein R1 and C1 compose in parallel reduction voltage circuit, and an end links to each other with the ac input end of bridge heap, and the other end is connected on the power taking body.The R2 string plays metering function between power taking body and bridge heap.The effect of U1 be will input alternating current convert the direct current that can use for D1～D9 to, D1～D9 connects in proper order, the positive pole of each lamp is connected on the negative pole of another lamp, the composition series circuit.After the series connection positive pole of lamp is connected on the positive pole of bridge heap, negative pole is connected on the negative pole of bridge heap.Figure (b) T is that transformer is with the pressure type circuit, wherein T is a transformer, R3 is a current-limiting resistance, U2 is the bridge heap, use transformer as voltage drop element, be connected in series the effect of a resistance R 3 as the restriction electric currents between one end of transformer output and the bridge heap, the ac input end that another termination bridge that transformer is exported is piled is on input two terminations and power taking body of transformer.The effect of U2 be will input alternating current convert to can be for the direct current of D10～D18 use.Resistance R 4 of serial connection plays metering function between the cathode output end of its jackshaft heap and the D10, the electric current that can supply D10～D18 to bear.D10～D18 is series connection mutually, and the positive pole of each lamp is connected on the negative pole of another lamp and forms series circuit.After the series connection positive pole of lamp is connected on the positive pole of bridge heap, negative pole is connected on the negative pole of bridge heap.
Five. transmissive body
Transmissive body is the lens of doing with transparent organic material that add on light emitting module 3, and the light fixture of different purposes is adopted different lens: common light fixture adopts concavees lens 5, and light is evenly dispersed.The direct projection that other also can adopt convex lens 6 to form the convergence of light or form light with plano lens 7.Adopt the sand material 8 that rubs to carry out encapsulated moulding at last.
LED lamp overall work flow process of the present invention is as follows:
With the electricity of 220V by power taking body place in circuit module, circuit module adopts electric capacity or transformer step-down mode, the 220V alternating current after piling rectification, gap bridge is converted into lower direct current through step-down, export the electric current and the voltage of capable for LED operate as normal then through the current-limiting resistance current limliting, it is luminous to promote luminescence unit LED, because LED adopts the different light emitting diode of dispersion angle to form, to around the light that sends and backward all the pass being reflected away toward the light on next door refractive body through the plating reflective membrane, the even orientation of light path is sent forward, the transmissive body (concavees lens or plano lens or convex lens) done by organic material again of light forward, the light that LED is sent evenly penetrates by the different purposes of light fixture.Form evenly dispersing of light as concavees lens, at last by the even soft ejaculation of the sand material that rubs.
The present invention adopts different lens, the light path that makes LED on demand light path evenly disperse, convergence or flat fire, adopt concavees lens among the embodiment, light is evenly exhaled, the visible range of light is enlarged, and the being seen light of different angles is even, and outermost adopts the material of the white sand that rubs to encapsulate, and minimizing light is radiometric to exterior object.It preferably is exactly to adopt LED different capacity, that emission angle is different to make up mutually that illumination effect reaches, and sees Fig. 5.For illumination effect more even, can adopt the mode of length difference, the different welding of angle LED, in central vertical centralized luminescent LED is installed, outer slightly one deck is welded in scatter-type LED lamp on the circuit board with more inclined to one side inclination angle, outermost layer scatter-type LED lamp angle is more inclined to one side, thereby light path is evenly penetrated, see Fig. 8.
The foregoing description is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
