Description

Lighting module

technical field

The present invention is a light-emitting module with multiple light-emitting diodes to provide display or lighting technology presented by multiple light sources. Signs, kanbans, instruments, large displays, lighting fixtures, etc. are related to the implementation of multi-light source presentation items.

Background technique

Light-emitting diode is a kind of luminous body that can produce eye-catching light effects, and has the characteristics of low power consumption, shock resistance, and non-breakage. In recent years, it has been widely used in tail lights, direction lights, brake lights, warning lights and traffic lights. , Large-scale advertising billboards, and high-brightness white light-emitting diodes have been used in flashlights, work lights, and emergency lighting equipment.

Due to the low power consumption of light-emitting diodes and no high heat generation, it is very suitable to directly provide the required power with the circuit board, and the circuit board can control its light-emitting mode, for example: by controlling the light source of the light-emitting diode to turn on and off And produce the implementation effect of directional lights or warning lights, a plurality of light-emitting diodes are arrayed and then the circuit board is used for timing control to produce the effect of active kanban.

Figure 1 shows a common light-emitting module implemented with light-emitting diodes, which is formed by directly welding a plurality of light-emitting diodes 92 on a circuit board 91 (each light-emitting diode 92 is directly inserted into the circuit with the provided pin 921 board 91 and welded), through the characteristics of easy configuration of various control circuits by the circuit board 91, power supply and light-emitting mode control are performed on each light-emitting diode; however, this implementation is not easy to disassemble when the light-emitting diode 92 is damaged and replacement, and does not have the effect of adjusting the angle of the light source, and is more limited by the shape of the circuit board 91 (flat or multi-layer flat structure), which can only be used for the arrangement of the light emitting diodes 92 in a plane.

Generally, the tail lights of automobiles or locomotives have two display methods, one is low-brightness display when driving at night, and the other is high-brightness display when braking. produce changes. Improper light source angle is likely to affect the sight of the driver behind, and even cause damage to the eyes of the driver behind, especially when stopping at the traffic light, the vehicles are in the state of brakes that are closely arranged in front and back. Each light emitting diode is provided with a preset maximum brightness or quantity to generate light source. If the light source is generated at a wrong angle, it is easy to hurt the eyes of the driver behind by the strong light, or affect driving safety.

As shown in FIG. 2, it is a light-emitting module with a light source angle change in the prior art. It is formed by laying a redirection component 93 between the circuit board 91 and the light-emitting diode 92, so that the light source of the light-emitting diode 92 generates an angle. Get changed to facilitate the control of the taillight light source.

However, the technology shown in FIG. 2 above is limited by the fact that the circuit board 91 can only provide LEDs 92 to be arranged in arrays on one plane. Although the redirection component 93 can cause slight fluctuations and angle adjustments of the LEDs 92, but The ups and downs and angle changes that can be produced are limited, and it is impossible to arrange the LEDs 92 in a more three-dimensional manner.

Secondly, in addition to the above-mentioned factors related to the angle of the light source, factors such as body shape, aerodynamics, and aesthetics also cause the implementation of light-emitting modules that only have a flat arrangement or a slightly undulating effect to still fail to meet the needs of industrial applications.

As shown in Fig. 3, Fig. 4 and Fig. 5, if the light-emitting diode 92 is to be able to produce a larger angle steering or to cooperate with a more three-dimensional car lamp, seat body, and projection cover, and to produce pluggable and replaceable effect, a plurality of light emitting diodes 92 can be respectively inserted on each socket 94 with a plug-in replacement effect, and then a plurality of wires 95 are used to configure the circuit of the socket 94, so that the socket 94 and the light emitting diode The 92 is available in free-steering or extended settings.

Each receptacle 94 is connected to a circuit board 91 provided separately after the grouping series connection of the wire 95 and the parallel connection between the groups, and is controlled and powered by the circuit board 91 so that each light emitting diode 92 can be set according to the mode set. Produces a predetermined light source effect. In practice, the light-emitting diode 92 and the socket 94 can be positioned at the position where the light source is to be displayed through the connection of a substrate 96 , such as between the lamp base 97 and the lampshade 98 of a motorcycle.

However, when the technologies disclosed in the above-mentioned Fig. 3, Fig. 4 and Fig. 5 are implemented in series between the receptacles 94, the entire light-emitting module will be interrupted due to a small part of the circuit, resulting in the loss of all light-emitting diodes 92. Can't emit light; If between each receptacle 94 is implemented in parallel, but can cause the usage amount of wire 95 to increase greatly. And if the receptacles 94 are grouped and then implemented in parallel outside the group and in series within the group, although the shortcomings of using series or parallel connections alone can be slightly improved, when a certain light-emitting diode 92 is damaged, it will still cause the LEDs connected in series to emit light. Groups of diodes 92 form a circuit interruption situation.

Furthermore, this kind of implementation of parallel connection outside the group and series connection within the group will make the configuration of the wires 95 more confusing and misconnection more likely to occur during the manufacturing process, and it is easy to use during the manufacturing process, transportation process, and assembly process. The entanglement, knotting or jamming of the wires 95 not only does not completely solve the aforementioned problem of circuit interruption, but also increases new troubles, which is obviously not a perfect solution.
