Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing to the present invention intoRow detailed description, the description of this part be only it is exemplary and explanatory, should not have any limitation to protection scope of the present inventionEffect.
Fig. 1-Figure 11 is please referred to, shows the present invention to realize the LED light source structure for shining and providing comprehensively, comprising:Luminous shell 1；There are three types of the states of composition for the tool of luminous shell 1, wherein
The first form are as follows: the luminous shell 1 includes top surface 101, bottom surface 103 and side 102；
Second of form are as follows: the luminous shell includes top surface 101, bottom surface 103, cambered surface 111 and side 102, describedTop surface 101 and the side 102 are connected by cambered surface 111；
The third form are as follows: the luminous shell includes top surface 101, bottom surface 103 and side 102, and the side 102 is wrappedMultiple planes are included, is connected between each plane by cambered surface 111 and forms the side 102.
Illuminator is set on each top surface 101, side 102 or cambered surface 111 under above-mentioned form, it is complete to achieveFace shines.
In the present invention program, in view of the prior art in clamp glass technology, since (clamp temperature is hot environment750-800 DEG C) can not by with actuator 2 LED light source together press seal in glass shell 4, the present invention to actuator 2 intoProtection is gone, to prevent high temperature from damaging, in which:
There is a heat-insulation chamber inside the luminous shell 1, be provided in the heat-insulation chamber, connect, drive with luminous shell 1The actuator 2 of 1 normal luminous of luminous shell, and connect with the actuator 2 and be pierced by leading for the luminous shell 1Electric pin 3；
Further, the luminous shell 1 by being integrally molded so as the substrate 11 of column structure, set on 11 lateral surface of substrateIlluminator 12 and heat-barrier material 13 enclose；Wherein: substrate 11 constitutes the top surface 101, side 102 or the top surface101, side 102 and cambered surface 111；The heat-barrier material constitutes the bottom surface 103；Specifically, the present invention provides following twoKind embodiment, makes actuator 2 be built in luminous shell 1.
Embodiment one: as shown in Figure 2-5,11 bending fold of substrate of strip is enclosed into cylindrical structure (substrate 11Aluminum substrate or copper substrate or irony substrate can be used or the substrate of other materials is made), the top surface 101 of cylinder and side102 by the uniform encapsulating light emitting chip 121 of fluorescent glue 120, to constitute the illuminator 12；Certainly, this programme can also be in substrate11 outer surface covering or does ceramic coating processing on surface at non-ferrous metal, to have the function that insulation and thermally conductive；In this implementationFolding position have two groups of foldings that concave bending part 1101, the actuator 2 is electrically connected by the bending part 1101.
In the present embodiment, it needs to carry out shaping bending to luminescence chip 121, the luminescence chip 121 of LED light is passed throughCOB mode is encapsulated in 11 outside circumference 102 of substrate and top surface 101 or further includes connecting with outside circumference 102 and top surface 101The cambered surface 111 connect；But due to needing to be bent luminescence chip 121, difficulty is larger, in this regard, the present invention provides another implementationExample；
Embodiment two: as illustrated in figures 7-11, the substrate 11 is by constituting several raised the 110 of side and constituting horizontal top surface101 upper cover is formed by connecting, wherein is smoothly connected between protrusion 110 and protrusion 110 by cambered surface 111, protrusion 110 and upper coverIt is provided with equally distributed luminescence chip 121；The outside of the substrate 11 is packaged with and connection identical as 101 structure of sideThe fluorescent glue 120 of the formation of side 101 circular top cover.
Through this embodiment, directly the luminescence chip of strip 121 can be attached in protrusion 110, without being adaptation base11 side structure of plate and qualitative bending, reduce realize shine comprehensively when, the production difficulty of light source for processing；It is simultaneously so that interiorPortion's cabling is convenient, and the cable hole 112 of connection heat-insulation chamber is opened up in the protrusion 110, will connect the conducting wire 5 of luminescence chip 121 fromCable hole 112 enters heat-insulation chamber, connects actuator 2.
It, can be by wiring board for the high temperature for further decreasing the generation of clamp glass shell 4 in the preferred embodiment of the present embodiment21 are set as structure as shown in figure 11, open up through-hole 113 in protrusion 110, wiring board 21 is placed in heat-insulation chamber, welding gun is usedSolder joint 6 is set across through-hole 113 and carrys out fixing circuit board 21, the wiring board 21 setting is in middle and upper part position, the isolation far from lower endMaterial 13.
The present invention also provides a kind of LED light, including the glass shell 4 for being packaged any of the above-described light source, wherein instituteIt states conductive pin 3 and stretches out the glass shell 4；Wherein conductive pin 3 is made of molybdenum rod 31, molybdenum sheet 32 and pin 33, described31 upper end of molybdenum rod connects actuator 2 by silver paste, and lower end connects the pin 33,31 lower end of molybdenum rod, molybdenum by molybdenum sheet 3232 entirety of piece and 33 upper end of pin are by press seal in the glass shell 4.
In the present invention, as shown in figure 12, for make LED light normal luminous actuator 2 circuit diagram, the circuit structure letterFor list, it can be achieved that toning, power factor is higher, can save electric energy.Specifically include power switch K1, rectification circuit and constant current output electricityRoad.
The rectification circuit is passed through using full bridge rectifier bridge heap BD1, the input terminal of rectifier bridge stack BD1 is made of four diodesIt crosses power switch K1 to be electrically connected with exchange, for rectifying with output ripple DC voltage the alternating current of input.
The constant current output circuit includes constant current chip EG2000A, resistance R2, resistance R3, capacitor C1, capacitor C2.WhereinVDD power port is connected through the cathode output end of capacitor C2 and rectification circuit, the VCC power port warp of constant current chip EG2000AThe connection of the cathode output end of capacitor C1 and rectification circuit, the first current regulation end of constant current chip EG2000A through resistance R2 with it is wholeThe cathode output end of current circuit connects, and the second current regulation end of constant current chip EG2000A is negative through resistance R3 and rectification circuitThe connection of pole output end, the supply port of constant current chip EG2000A and the cathode output end of rectification circuit connect.
Constant current chip EG2000A is pressed into the Rectified alternating current of rectification circuit output according to the on-off of power switch K1Row transformation is to export different Constant Direct Current electric currents.The LED of the constant current output port of constant current chip EG2000A and COB encapsulation is sent outThe cathode terminal of optical chip 3 connects, and the anode tap of LED luminescence chip 3 and the cathode output end of rectifier bridge stack connect, therefore can basisThe different Constant Direct Current electric currents of constant current chip EG2000A output, issue the light of different-colour, and then make to issue by different-colourLight be in torch luminance.
