Problems solved by technology

Since the current 12V23A is an industrial application battery, it is difficult for the general market and residents to buy it! In the past, it was difficult for customers to purchase this special battery in the local market, and they could only purchase specific batteries through the manufacturer, thus increasing the cost
In addition, due to the insufficient voltage of the battery, the current lighting hinge can only have 3 LED lights, and it will not be able to pull any more

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0016] A lighting hinge, the lighting hinge includes 4 LED lamp beads D1-D4 arranged in parallel, and a battery pack, a step-up drive module U1 is connected between the positive pole of the battery pack and the positive pole of the LED lamp bead, the The negative electrode of the LED lamp bead is coupled to the negative electrode of the battery pack; the battery pack includes at least one battery of 0.8V-1.5V.

[0017] see figure 1 The step-up driver module U1 includes a power supply pin VDD, a power supply pin LX, and a ground pin VDD. The positive pole of the LED lamp bead is connected to the power supply pin VDD (the first pin), and the negative pole is connected to the ground pin GND (the first pin). 3 pins); the supply pin is coupled to the positive terminal of the battery pack; an inductor is connected between the supply pin and the sup...

Abstract

The invention discloses an illumination hinge which comprises N parallel-connected LED lamp beads and a battery pack. A voltage-increasing type driving module is connected between a positive electrode of the battery pack and positive electrodes of the LED lamp beads. Negative electrodes of the LED lamp beads are coupled to a negative electrode of the battery pack. The battery pack comprises at least one battery of 0.8 V-1.5 V. N is larger than or equal to 4. The voltage-increasing type driving module is used, the LED lamp beads are arranged in a parallel-connecting mode, the voltage class is lowered, accordingly, a common number seven (AAA) battery can be used as a power supply for driving, a customized battery does not need to be bought, and maintaining cost is lowered. In addition, the number of the LED lamp beads can be well increased by parallel-connecting arranging, and low-cost and high-efficiency illumination is achieved.

Description

technical field [0001] The invention relates to the decorative lighting field of cabinets and wardrobes, and more specifically relates to a lighting hinge. Background technique [0002] Currently, lighting hinges. The shell is made of ABS+PC material, three LED lamp beads, and a contact switch. The driving voltage of each LED is 3V-3.6V. If there are 3 LEDs, the working voltage is above 9V. You can only choose the battery power supply: model 23A, one 12V battery, and it cannot be driven by ordinary batteries. , and the circuit uses the channeling form, that is, the 23A battery. With this circuit, it can only support 3 LEDs at most. In terms of service life, and due to the high working voltage, a battery can only be used for about 3 months. Since the current 12V23A is an industrial application battery, it is difficult for the general market and residents to buy it! In the past, it was difficult for customers to purchase this special battery in the local market, and they co...
