Vertical drive power supply for lamps

Abstract

The invention discloses a vertical driving power supply for a lamp, which comprises an integrally formed shell and a tail cover, one end of the shell is closed and the other end has an opening, the tail cover is fixedly connected with the opening end of the shell, and a hole is arranged on the tail cover It also includes a circuit board with a control circuit, a switch for generating a pulse signal and a seal, at least a part of the circuit board is installed in the cavity of the housing, and one end of the switch is welded and fixed on the circuit board, The other end of the switch is a free end. After the seal is installed in the hole on the tail cover, the hole is sealed. After the tail cover and the housing are fixed, the seal and the free end of the switch form abutment. One end of the seal exposed to air. The invention has the advantages of simple structure and good waterproof.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a vertical driving power supply for a lamp. Background technique [0002] The existing LED drive power supply with control function generally adopts a horizontal structure, such as figure 1 with figure 2 As shown, the horizontal structure includes a housing, a circuit board, a conductive button, and an output waterproof socket. The housing is composed of an upper cover 1 and a lower cover 2. The upper cover 1 is provided with a mounting hole. When assembling, the conductive button 3 is assembled In the installation hole, the circuit board 4 is installed in the shell, and the output waterproof socket 5 is installed in the groove at the tail of the upper cover 1. After closing the upper cover 2, the upper cover 1 and the lower cover 2 are welded by ultrasonic waves, and the output waterproof socket 5 and the upper cover 1 and the lower cover 5 are ultrasonically welded to form...

AI Technical Summary

Problems solved by technology

However, during use, it is necessary to form a pressing operation on the conductive button 5. During the pressing process, the pressing force is transmitted to the second circuit board 3 through the conductive button 5. Since the second circuit board 3 passes through the first circuit board 2 The supporting effect or being installed in the cavity of the tail cover 4 in an over-fitting manner will inevitably cause the second circuit board 3 to be deflected or loose. A gap is generated, and when the conductive button 5 loses the reverse force of the second circuit board 3, a gap is also generated between the conductive button 5 and the mounting hole of the tail cover, thereby losing the waterproof effect

In addition, since the conductive button 5 must be vertically attached to the second circuit board 3, if the conductive button 5 is installed on the casing like an LED horizontal drive power supply, such an assembly method cannot be completed because: when the first circuit board After the board 2 is inserted into the integrally formed housing 1, due to the limitation of the assembly space, it is impossible to generate mutual force between the first circuit board 2 and the conductive key 5 like the LED horizontal drive power supply, which will cause the first There is a gap between the circuit board 2 and the conductive button 5, and a gap between the conductive button 5 and the housing 1

[0007] Second, the LED vertical drive power supply uses 2 circuit boards to form this circuit control. The waterproof of the casing 1 is solved, but the assembly process between the first circuit board 2, the second circuit board 3 and the conductive button 5 Very complicated, low mass production efficiency, and high production cost after using two circuit boards
