Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of infrared human body induction lamps, in particular to a lamp with a physical anti-short circuit protection structure. Background Art
[0002] The active infrared working mode has the characteristics of good stability and strong anti-interference. It is equipped with infrared decoding method and is widely used in commercial and industrial occasions with high requirements. It can automatically turn on the lighting and automatically delay turning off after people leave, eliminating human waste of energy, extending the service life of electrical appliances, and integrating energy saving, convenience and security.
[0003] Currently, the infrared human body sensor lights on the market do not have short-circuit protection. When the aluminum is not cut flat or the soft light strip cannot be flush with the aluminum, the spring conductor will contact the aluminum at the same time, which will cause a short circuit and generate a huge instantaneous current that will burn out the sensor. Utility Model Content

[0009] Through the above technical solution, the human body is sensed by the set infrared sensor. The working principle of the infrared sensor is based on the changes in infrared rays released by the human body. When the human body enters the sensing range of the infrared sensor, the infrared sensor receives the changes in the infrared radiation of the human body, and then converts it into an electrical signal, triggering the lighting system and lighting up the soft light strip. The infrared sensor model uses RE200B human infrared pyroelectric sensor.
[0010] Preferably, a through slot is provided on the surface of the sensor housing cover from front to back, and the conductive spring passes through the through slot.
[0011] With the above technical solution, the conductive spring is extended to the rear side of the circuit board through the provided through slot.
[0012] Preferably, there are two conductive springs, which are staggered on the left and right and serve as positive and negative poles respectively. The positive and negative poles of the two conductive springs are electrically connected to the positive and negative poles of the soft light strip.
[0013] Through the above technical solution, the design of two conductive springs, one on the left and one on the right, can effectively prevent the conductive springs from contacting the aluminum material at the same time, thereby avoiding the problem of short circuit.
[0014] Preferably, the circuit board is electrically connected to the input line, the conductive spring, and the spring conductor, and the infrared sensor is electrically connected to the spring conductor.
[0015] Through the above technical solution, a complete circuit is formed, so that the soft light strip can be opened and closed normally.
[0016] Preferably, a mounting seat is installed on the rear side of the aluminum material.
[0017] Through the above technical solution, the aluminum material is installed through the mounting seat.
[0018] Compared with the prior art, the present invention provides a lamp with a physical short-circuit protection structure, which has the following beneficial effects:
[0019] When installing the circuit board of the lamp with this physical anti-short-circuit protection structure, due to the front-to-back structure of the conductive springs, the conductive spring close to the flexible light strip is the negative pole, and the negative pole contacts the load first. After the negative pole conductive spring is fully inserted, the positive pole conductive spring will enter. Even if the guest operates with the power on, the risk of short circuit can be effectively avoided, and the damage caused by short circuit due to incorrect operation of the guest is avoided, which has high safety.

[0031] Furthermore, a mounting seat 5 is installed on the rear side of the aluminum material 8 . Specifically, the aluminum material 8 is wall-mounted through the mounting seat 5 .
[0032] Working principle: First, during the installation of the circuit board 3, due to the front-to-back structure of the conductive springs 302, the conductive spring 302 close to the soft light strip 6 is the negative pole, and the negative pole contacts the load first. After the negative pole conductive spring 302 is fully inserted, the positive pole conductive spring 302 will enter. Even if the guest operates with power on, the risk of short circuit can be effectively avoided, and the damage caused by short circuit due to incorrect operation of the guest can be avoided, with high safety.
