Abstract
The present invention relates to a soft-light light emitting diode traffic light which is basically composed of a plastic fiber light conducting board 1, light emitting diodes 2 (on the light emitting surface on the periphery of the light conducting board along the surface of the light conducting board), a soft printed circuit board 3, light emitting diodes 4, an insulating sealing strip 5, a lighting material layer 6, etc., wherein the soft printed circuit board 3 is welded with the light emitting diodes 2 and connected with resistors in series and parallel, the light emitting surface in the center of the surface of the light conducting board is perpendicular to the light emitting diodes 4 on the surface of the light conducting board, and the lighting material layer 6 is printed on the back surface of the light conducting board; the lighting material layer 6 is not disclosed in the schematic diagram in the specification. Since the light emitting diodes are connected with each other in series in each group and connected with the current-limiting resistors in parallel in groups, the service life of the light emitting diode is extended; the lighting-start voltages of the light emitting diodes do not need to be strictly consistent, and the required high-brightness can still be obtained; the advantage of long service life of the light emitting diode is fully displayed. When a solar battery is laid on the top surface of the traffic light, the traffic light can operate as usual when the power is off. The present invention belongs to the technical fields of optoelectronics and lighting.
Description
Technical field
The present invention relates to the soft light luminous diode traffic lights of a kind of invention, belong to optoelectronics and lighting field.
Background technology
The traffic control traffic lights major part of big city arterial street adopts light emitting diode and has replaced incandescent lamp now.Major advantage is long-life, high brightness, low-power consumption.
But present light emitting diode traffic lights adopt the simple parallel connection of light emitting diode substantially, and shortcoming must strict test be selected light emitting diode and play bright voltage consistance in a light fixture, has improved cost.As failing to have accomplished the consistance of bright voltage sometimes, the long-life that can not give full play to light emitting diode itself.
Summary of the invention
A kind of soft light luminous diode traffic lights device of the present invention for overcoming above shortcoming, guarantees light emitting diode due long-life of traffic lights, high brightness, improves the visual angle simultaneously and reduces cost.
Its basic structure comprises: the light emitting diode 2, welding light emitting diode 2 that advances light guide plate by plastic optical fiber light guide plate 1, at the light guide plate periphery along light guide plate surface edge and the series-parallel software printed circuit board (PCB) 3 of resistance, light guide plate centre of surface are perpendicular to light emitting diode 4, insulation sealing strip 5, light guide plate back up one deck lighting material layer 6 on light guide plate surface, and light fixture adopts common light fixture.
Principal feature is that the light emitting diode 2 of 70% above quantity is to inlay into light guide plate in light guide plate periphery light-emitting area along light guide plate plane surface direction, make luminous soft, accounting for 30% of sum with light guide plate centre of surface light-emitting area perpendicular to the light emitting diode 4 on light guide plate surface cooperates, guarantee that promptly brightness is luminous again soft, the expansion visual angle.
Lighting material layer 6 is very thin, does not mark among the figure.
The light emitting diode traffic lights of present common use, light emitting diode all are simple parallel-connection structures, and this just brings light emitting diode must strictly test the consistance of selecting luminous bright voltage.Because the lumination of light emitting diode wafer has separation property, so that light emitting diode plays bright voltage is also inconsistent, the light emitting diode in a light fixture will be selected consistance meticulously, must bring the bid height, and cost improves.
Characteristics of the present invention, the light emitting diode in a brightness class needn't be selected meticulously.Take to improve installing, be that light emitting diode is not simple parallel connection, but adopt one group of series connection (with how many light emitting diode series connection considering in a group) with the voltage global design of being adopted, add a current-limiting resistance after one group of series connection, consider power problems, select current-limiting resistance between 0.5 to 2 volt of the current-limiting resistance two ends step-down.And then many groups are in parallel.Needn't strict select the consistance of bright voltage like this, some light emitting diode of easy burn-out does not reduce cost.Give full play to the light emitting diode life-span itself.The electric current that keeps light emitting diode to pass through when design and installation is 20mA (normally uses electric current, just guarantee the long-life).
The present invention has following good effect and advantage:
This structure is installed, and power supply needn't strictness be a constant current source, and power supply can be a direct current, also can be to exchange.
Because 70% light emitting diode is inlayed into along the light guide plate surface direction at the light guide plate periphery, utilize plastic optical fiber material and lighting material characteristic to light, luminous soft, cooperate with light guide plate center light emitting diode (sum 30%) again, the luminous height that promptly guarantees, luminous again soft, the visual angle is expanded again.
Mix solar cell (being installed in traffic lights light fixture end face), solving interim outage traffic lights can work as usual.
Summary of drawings
Fig. 1 is that the soft light luminous diode traffic lights of the present invention are faced the face synoptic diagram.The do not draw skim lighting material layer of light fixture and light guide plate back up of this synoptic diagram.
Fig. 2 is the string and the connected mode of light emitting diode.
Embodiment
A kind of soft light luminous diode traffic lights device comprises plastic optical fiber plate 1, inlays light emitting diode 4, insulated enclosure bar 5, light guide plate back up one deck lighting material layer 6 composition basic structure in the light guide plate along the surperficial vertical light guide plate of light emitting diode 2, welding light emitting diode and the series-parallel software printed circuit board (PCB) 3 of resistance, the light guide plate centre of surface surface of inlaying the light guide plate periphery of light guide plate.
Guaranteeing brightness, luminous soft, under the big preceding topic in visual angle, the number of light emitting diode 2 and light emitting diode 4 not necessarily strict 70: 30 can be made adjustment in design.
Light guide plate is that plastic optical fiber material is made in a kind of example, and leaded light backboard surface printing lighting material layer is as 8100 series inks.
Light guide plate can be that transparency is good in a kind of example, and the life-span, long Other Engineering plastic material was made, back of the body surface printing skim lighting material.
Light guide plate back side frosted or hacking in a kind of example also have effect same.
In a kind of example, light guide plate centre of surface partly light emitting diode pipe cap partly spills the light guide plate front surface.
In a kind of example, the light guide plate centre of surface partly can bore or be injection molded into the hole, garden of certain depth on leaded light backboard surface light emitting diode 4 is installed, the diameter in hole, garden and the degree of depth are worked good with the diameter and the length of the light emitting diode that is adopted, can inlay the optical diode of setting out fully, but the light guide plate front surface stays also skim can not bore (or not injection moulding is saturating).
The thickness of light guide plate depends on the length of the diameter and the pipe of selected light emitting diode, to inlay the optical diode of setting out.
Light guide plate can be hollow in a kind of example, and two surface wall have certain thickness and guarantee certain intensity simultaneously.
