Description
Technical field
The present invention relates to a kind of lamp bar using clubfoot circuit connector to have a down dip, particularly relate to a kind of use clubfoot circuit even
Connect the structure of the lamp bar that device has a down dip, and the structure of the display screen being made up of it.
Background technology
Fig. 1 is the distribution curve flux figure (i.e. curve of light distribution figure) of a kind of typical LED, sees Fig. 1, it is known that
The upper relative light intensity in 0 ° of direction (i.e. the normal direction of light emitting end surface) of distribution curve flux is maximum, is 100%.At currently used lamp bar
In display screen, the metope orthogonal (the most in horizontal direction) that in LED element, the largest light intensity direction of wafer is installed with display screen.
Owing to display screen is loaded on eminence more, if as a example by the distribution curve flux of Fig. 1, when people look up viewing, relative light intensity when looking up 30 °
Being 55.3%, when looking up 45 °, relative light intensity is 33%, looks up the biggest relative light intensity of angle the least, i.e. brightness perception is the darkest.And show
Light intensity more than screen horizontal direction causes light pollution to high-rise resident.Therefore, the largest light intensity of LED element how is made full use of
Visual angle, improves and fills the perception brightness of pinnacled LED display, reduces unexpected light pollution, and simple in construction, manufactures and tie up
Protect easily, be the problem that technical staff does one's utmost to solve in recent years.
Chinese patent document CN204516794U discloses " a kind of Surface Mount LED ", and Fig. 2 is one of its schematic diagram, sees
Fig. 2, it is mainly characterized by LED wafer 14 position and has a down dip an angle higher than Guang Bei 19 center and light cup rim of a cup end face 201, and
The light emitting end surface of LED wafer 14 is still parallel with the solder side of pin 13, and relative light intensity maximum direction is still without having a down dip.Although this can
The brightness perception that has a down dip of this Surface Mount LED can be improved, but with the distribution curve flux law-analysing of LED element, lightening efficiency is the highest.
Chinese patent document CN205334893U discloses " LED element, LED lamp bar and display screen with angle ", and Fig. 3 is
One of its schematic diagram, sees Fig. 3, the light emitting end surface 18 of LED wafer 14, and the part being in outside housing 11 with pin 13 is formed
Between welding plane 17, having an angle α, α is less than 90 ° more than 0 °.Although this can make relative light intensity maximum direction have a down dip to increase
Add the brightness that has a down dip of this Surface Mount LED, but LED element must be reformed by this, increase development risk and cost.
Chinese patent document CN202695542U discloses " a kind of asymmetric direct plugging-in LED pipe ", and Fig. 4 is its signal
One of figure, sees Fig. 4, and its Lamp cup 3 and package main body 1 are asymmetrical shape, makes the light that LED wafer 5 sends by asymmetric lamp
The eccentric reflection of cup 3 and the deflection refraction of asymmetric package main body 1, go out light deflection secondary superposition, makes LED go out light and has a down dip increasing
Bright.But with the distribution curve flux law-analysing of LED element, its relative light intensity maximum direction is still without having a down dip, and lightening efficiency also can change
Enter；And LED element must be reformed by this, increase development risk and cost.
Chinese patent document CN201498157U discloses " on a kind of LED display lamp bar have a down dip structure ", and Fig. 5 is that it shows
One of being intended to, see Fig. 5, lamp bar 2 is installed on vertical beam 3 by the support 1 that has a down dip.Although this can make under relative light intensity maximum direction
Incline to increase the brightness that has a down dip of lamp bar, but the power line of lamp bar 2, data wire, control line all must use cable and two pairs of connectors
Being connected with vertical beam 3, structure is complicated, increases fault rate and cost；And so (i.e. lamp interspace is saturating for the display screen air permeability rate of structure
Empty area and the ratio of lamp bar display area) still there is the further place improved.
Chinese patent document CN204904759U discloses " the glass curtain wall screen module at band angle of inclination ", and Fig. 6 is that it shows
One of being intended to, see Fig. 6, the circuit card of lamp bar one end is connected on longitudinal keyset tilt on the circuit jack arranged, and makes
The extended surface 391 of the light-emitting area of lamp bar LED becomes angle α with the extended surface 392 of the installed surface of glass curtain wall screen.Although this can make
Relative light intensity maximum direction has a down dip to increase the brightness that has a down dip of lamp bar, but owing to lamp bar and longitudinal keyset are that side is inserted even
Connect, another side longitudinal direction keyset could be installed after longitudinal keyset can only be inserted by multiple lamp bars during installation,
Therefore installation difficulty；And it is the most highly difficult to keep in repair replacing trouble light bar；And so the display screen air permeability rate of structure still has into one
The place that step is improved.
From these Exemplary patents cited above it will be seen that industry technical staff practises to solve lamp bar display screen
The problem that has a down dip of LED, to improve the perception brightness filling pinnacled LED display；Technical staff also does one's utmost to wish to improve lamp
Bar display screen air permeability rate, and simple in construction, manufacture and safeguard easily；First three patent is to start with improvement from LED, latter two
Patent is that the mounting structure from lamp bar display screen is started with improvement, but all brings new problem or still have the place of improvement further.
Summary of the invention
The technical problem to be solved in the present invention is how to make full use of the largest light intensity visual angle of LED element, improves and is contained in height
The perception brightness of LED lamp bar display screen at place, improves its air permeability rate simultaneously, and improving cost is cheap, simple in construction, manufacture and
Safeguard easily.
In order to solve above-mentioned technical problem, first technical scheme of the present invention there is provided a kind of use clubfoot circuit even
Connecing the lamp bar that device has a down dip, its ingredient includes the lamp bar PCB equipped with multiple light-emitting components and circuit connector, on lamp bar PCB
