Embodiment
In being discussed in more detail below, with reference to the attached drawing for the part for forming this specification, wherein, show in an exemplary manner
It can implement the specific embodiment of the present invention.On figure, such as " top ", " bottom " directional terms refer to described attached drawing
Direction use.Since the component of the embodiment of the present invention can be placed on many different directions, so direction term is only used for
Illustrate, without the meaning of any restrictions.It should be understood that other embodiments can be used, and without departing substantially from the present invention
Scope on the premise of can carry out structure or logical changes.Restricted meaning is understood not to so being described below in detail
Think, and the present invention is defined by the appended claims.
If it should be understood that especially indicated without other, the feature of different exemplary embodiment described herein
It can be bonded to each other.
Fig. 2 shows the schematic diagram of lamps and lanterns according to the present invention.The lamps and lanterns 200 be, for example, advertising lamp or identification light, its by
The lighting device 100 of multiple series connection is formed in the form of coiling.Lighting device 100 is set by two light emitting modules 1 and for example respectively
The electrical connector 2 for being calculated as cable or electric wire is formed, and wherein electrical connector is not only that each light emitting module 1 is powered, but also is being tied
Two light emitting modules 1 are linked together in terms of structure, the section between two light emitting modules 1 is the connection of electrical connector 2
Section 3.
The light emitting module 1 of each lighting device 100 has original spacing in the case where not influenced by external force, but in order to
Being combined into the lamps and lanterns 200 with specific pattern needs these light emitting modules 1 of illumination apparatus 100 to apply pressure in closure
Power.This causes in the illustrated case, and the distance between two light emitting modules 1 are less than original spacing, while again smaller than position
In the length of a pair of connecting portion section 3 between the two, therefore connect segment 3 is deformed.According to the present invention, connect segment 3
Only in the plane internal deformation parallel to paper.That is, connect segment 3 is designed as in the height perpendicular to light emitting module 1
Either one in the plane in direction is upwardly-deformed.Therefore the connect segment 3 to overarch is bent in the plane parallel to paper simultaneously
The illuminating effect of the lighting device 100 of light beam is not influenced to send on the direction perpendicular to paper.
Fig. 3 shows sectional view of the lighting device in closure in Fig. 2.By the attached drawing it can be clearly seen that
Connect segment 3 has the bar tee section extended on the short transverse h of light emitting module 1.This company with non-circular longitudinal section
When socket part Duan Qi both ends are subject to opposite extruding force respectively, only there is the trend towards horizontal direction deformation, can with reference to Fig. 3
To find out, connect segment 3 only can the flexural deformation in the side zones of light emitting module 1, the side zones be located at shine mould
Between the top and bottom of block 1.This is because the deformation produced inside connect segment 3 in longitudinal direction, i.e. on short transverse h
Power is less than the deformation power produced in a lateral direction.Ideally, the height H of connect segment 3 is more than 3 times of width
W。
In addition, two pairs of openings 4 matched with the vertical sectional shape of connect segment 3 are offered on light emitting module 1.These openings
4 are located in the two side walls being oppositely arranged of light emitting module 1 respectively as feed opening and outlet opening, it is possible thereby to for connection
Section 3 is extended through inside light emitting module 1, and is electrically connected with the cathode of electronic device therein and anode.
In addition, in order to avoid light emitting module 1 emergent light light path in a lateral direction, i.e. perpendicular to short transverse h's
Section 3 is connected on direction to stop, opening is preferably arranged on to the first area of the latter half of the side wall of light emitting module 1
In, it is possible thereby to make light-emitting surface of the connect segment 3 away from light emitting module 1.
In a unshowned embodiment, opening can also be located at the two side walls adjacent to each other of light emitting module respectively
On.Two lighting devices so designed can connect the lamp string section to form square.
In a unshowned embodiment, electrical connector, will be each in a manner of grafting for example as just connect segment
A light emitting module is electrically connected.
In a unshowned embodiment, such as a pair of of electric wire can be integrated into a unique electrical connector, it two
End has two pair of wire connection terminals respectively.It is possible thereby to only only open up each use respectively in the two side walls of light emitting module
In the strip gab of the electrical connector.It is possible thereby to reduce the manufacture cost of lighting device.
Fig. 4 shows the schematic perspective view of the connect segment in Fig. 2.Electrical connector 2 with connect segment 3 includes conduction
Core 31 and the insulation sheath 32 for being coated on center, in longitudinal section, conductive core 31 is circle, and the insulation sheath 32 is
Bar shaped.Conductive core 31 is for example made of one or more metallic fiber, and insulation sheath 32 is made of flexible plastics.In order to
Ensure that the deformation direction of connect segment 3 is dependent only on the vertical sectional shape of insulation sheath 32, preferably by conductive core 31 and absolutely
Edge crust 32 is coaxially disposed.
As shown in figure 3, the electrical connector 2 of bar shaped is very easy to bending or deformation on the width of its longitudinal section, by
This is avoided arching upward in its height direction.
In addition, although only with respect to a kind of special characteristic for disclosing the embodiment of the present invention in numerous embodiments or
Aspect, but as required by any given or application-specific, these features or aspect can be with one of other embodiment
Or a number of other features or aspect are combined.
It these are only the preferred embodiment of the present invention, be not intended to limit the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification for being made within the spirit and principles of the invention, etc.
