Description
Technical Field
[0001] The utility model relates to the technical field of lighting equipment, in particular to a high-voltage light-emitting module dedicated to light-emitting characters. Background Art
[0002] At present, the advertising luminous characters, light boxes, and decoration and decoration industries realize luminous display or light rendering by installing luminous low-voltage 12V light strips and low-voltage 12V modules. In addition, before the low-voltage 12V light strips and low-voltage 12V modules are turned on, the AC220V mains power needs to be transformed into DC12V through a dedicated LED power supply. Since the luminous characters have more strokes, more light strips or modules are used, and the strings are also longer, this leads to the problem of voltage drop and uneven light emission in the power supply voltage. In addition, the LED power supply has low efficiency, high power, high energy consumption, low brightness, and poor overall light effect. It is usually necessary to arrange more luminous light strips or modules to improve the light effect. At the same time, after the existing luminous modules are assembled in the advertising luminous characters and light boxes, since the advertising luminous characters or light boxes are usually placed outside, water is easily accumulated when it rains, and the waterproof effect is not very good, which causes the luminous modules to fail and affect the service life.

[0014] Reference Figure 1-2 As shown, a high-voltage light-emitting module dedicated to light-emitting characters includes a carrier 1 and a circuit board 2. The two ends of the carrier are provided with wire through holes 8 and a card platform 9, and a sinking groove 11 is provided in the middle. The circuit board 2 is arranged in the sinking groove 11, and L soldering points 6 and N soldering points 7 are respectively provided on both sides of the circuit board. The L soldering points located on the two lateral sides of the circuit board are connected together, and the N soldering points located on the two lateral sides of the circuit board are connected together. The L soldering point on the lateral side of the circuit board is also connected to a bridge stack 13, a lamp bead 3, a resistor 15 and a buck IC 16 in sequence, and the resistor is connected to the N soldering point on the same lateral side of the circuit board. A lens 4 is provided on the outside of the lamp bead 3, and a sealing body 5 is provided on the outside of the circuit board.
[0015] A groove 10 communicating with the wire through hole 8 is also provided near the end of the carrier 1 .
[0016] The shape of the lens includes a spherical shape, and the sealant completely seals the sinking groove. The sealant adopts a glue-filling process, and the sealant material has good heat dissipation performance and is resistant to yellowing. In one embodiment, the lamp bead is 70V, the resistance is 101 ohms, the lens emits light at 150 degrees, and the brightness and clarity of the luminous characters are significantly improved.
[0017] The length of the carrier is 75-85 mm and the width is 10-15 mm. The inner dimensions of the sinking groove meet the requirements for placing the circuit board. In order to facilitate construction, double-sided tape 12 is provided at the bottom of the sinking groove.
[0018] In the preferred embodiment, the length of the carrier is 80 mm, the length of the sinking groove is 66 mm, and the width is 12 mm.
[0019] The circuit board is connected to the carrier through the card platform, and the card platform is located between the L soldering point and the N soldering point. The wire 14 is inserted into the wire perforation 8 along the groove 10. The card platform can effectively separate the L pole and the N pole of the wire, which is convenient for spot welding, and also avoids short circuit and lamp burning, effectively improving the quality and service life of the light-emitting module; after the spot welding is completed, the double-sided tape at the bottom of each carrier is torn off the surface, and at this time, the light-emitting module connected by multiple wires is gradually bonded to the light-emitting font according to the stroke trajectory. The wires of each light-emitting module are arranged below the two ends of the carrier, which plays a fixing role and is neatly arranged. The position close to the light-emitting module does not need to be nailed separately to fix the wires, which reduces the working hours, is convenient for installation, and effectively improves the work efficiency.
