The specific embodiment
Below be through particular specific embodiment technology contents of the present invention to be described, those skilled in the art can understand other advantage of the present invention and effect easily by the content that this specification disclosed.The present invention also can implement or use through other different specific embodiment.
See also the three-dimensional exploded view of Fig. 1 for the dispersed LED light fixture 1 of tool light source of the present invention, the dispersed LED light fixture 1 of this light source comprises: housing 15, circuit substrate 11 and lampshade 14.Must explanation be that LED light fixture 1 of the present invention does not exceed with the LED bulb lamp shown in scheming, and can be applicable on the LED light fixture of other type yet.
This circuit substrate 11 is to be contained in the housing 15; This circuit substrate 11 is provided with LED12 and reflector 13; Through the emission light of this reflector 13 with reflection LED12; And this circuit substrate 11 is to be electrically connected on power drives part 16, and the LED12 that drives this circuit substrate 11 with the power supply through this power drives part 16 is luminous, and this power drives part 16 also is contained in this housing 15.These reflector 13 surfaces coated are furnished with the reflexive material of tool, and wherein, this reflective material can be titanium dioxide (TiO2) or zinc sulphide (ZnS); Perhaps, this reflector 13 can be speculum.
This lampshade 14 is to be connected with this housing 15, and coating circuit substrate 11 and reflector 13 are invaded in this housing 15 to prevent dust, and these circuit substrate 11 telecommunications are handled or the reflection efficiency of reflector 13 and influence.
The mode that can adopt engaging or be threaded is connected this lampshade 14 with this housing 15, or circuit substrate 11 is fixed in this housing 15.With Fig. 1 is example, and the edge of this circuit substrate 11 is to snap in the groove 151 of housing 15 inside, and the edge of this lampshade 14 is to snap in the groove 152 of housing 15 outsides, can be convenient to assembling by this, simultaneously escapable cost.
What specify in addition is, because the power drives part 16 that is shown among Fig. 1 is to use general prior art with electric connection 17, so will not give unnecessary details for literary composition at this.Moreover, if do not consider the problem that dust is invaded, when the setting that can omit lampshade 14.
Then, as shown in Figure 2 is the reflection start schematic diagram of launching light for the reflector reflection LED of the dispersed LED light fixture of tool light source of the present invention.As shown in the figure; The light L1 that LED12 launched on being arranged at circuit substrate 11 penetrated in 13 last times of reflector; This reflector 13 reflects the emission light L1 of LED12 and produces reverberation L2; The reverberation L2 that passes through to be produced increases the illumination zone of LED12, and is promptly as shown in the figure, increases the irradiating angle θ of light through this reverberation L2.
Moreover the reflector with the dispersed LED light fixture of light source of the present invention is not limited to the cylinder of Fig. 1, structure that also can be shown in Fig. 3 A, Fig. 3 B, Fig. 3 C and Fig. 3 D, and it is every that to produce reflecting effect all applicable with the structure of the illumination zone that increases LED12.
In addition; As shown in Figure 4, be the sectional view that has another embodiment partial structurtes of the dispersed LED light fixture of light source for of the present invention, be simplified illustration and graphic; Present embodiment only just proposes explanation with the difference of earlier figures 1; In the present embodiment, be that reflector 13 ' is arranged at lampshade 14 ' on a surface of circuit substrate 11 ', so the emission light that can reflect from the LED12 of this circuit substrate 11 ' through the reflector 13 ' of this lampshade 14 '.
Moreover, as shown in Figure 5, be for the dispersed LED light fixture of the tool light source of the present invention three-dimensional exploded view of an embodiment again, be simplified illustration, here only just with the difference proposition explanation of Fig. 1.The dispersed LED light fixture 2 of the tool light source of present embodiment also comprises radiating seat 24, and its housing 25 has a plurality of perforates 251, and the LED22 on the circuit substrate 21 is a plurality of.
In the present embodiment; This reflector 23 is the positions that are arranged at the geometric center of these a plurality of LED22; The light that this a plurality of LED22 is launched obtains maximum illumination zone and more uniform brightness via reflector 23 reflection backs; For example, after the light that LED22 launched of this LED light fixture 2 reflected via reflector 23, its illumination zone can be greater than 120 degree.
This radiating seat 24 is to be connected in circuit substrate 21 dorsad on the side of LED22 light emission direction; And radiating seat 24 has a plurality of thermal columns 241 on the surface of LED22 light emission direction dorsad; Be arranged at the heat that the LED22 on the circuit substrate 21 produces in order to conduction, and the length of these a plurality of thermal columns 241 is to be shortened to edge gradually by this centre of surface place.
Generally speaking, the temperature of circuit substrate 21 centers is higher usually, so can increase area of dissipation and reach the preferable heat effect of loosing through being positioned at the long thermal column 241 of radiating seat 24 centers and length.In addition; As shown in Figure 6; Because this housing 25 is located on circuit substrate 21 and locates to have a plurality of perforates 251 all around with radiating seat 24; And thermal column 241 length of these radiating seat 24 edges are shorter, thus can not stop or hinder flowing of radiating seat 24 center air, so the heat of the thermal column 241 of center can the convection current dissipation via air promptly.Therefore, through the perforate 251 of this housing 25, make the hot-air carry heat can be apace in the housing to around discharge, and then promote radiating efficiency.
In sum; The LED light fixture that tool light source of the present invention is dispersed can reflect the light that LED launches through reflector, makes its illumination zone greater than 120 degree; With the irradiated area that increases the LED light fixture and promote lightness, and then reduce power consumption and setting, safeguard the cost of light fixture.In addition, of the present invention have the dispersed LED light fixture of light source when promoting irradiated area, also has the effect that promotes the LED heat radiation, thus can make the LED bulb can maintain the state of normal temperature, and the luminous efficiency and the service life that help promoting the LED bulb.
Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
