Description
Technical Field
The invention relates to a lamp which is arranged on a tower crane in a building construction site to provide illumination, in particular to a lightning-stroke-resistant and error-connection-resistant tower ceiling lamp.
Background
The tower crane is a hoisting device (also called tower crane) on a building construction site, and can be used for hoisting construction raw materials such as reinforcing steel bars, wood ridges, concrete, steel pipes and the like for construction.
The tower ceiling lamp is arranged on the tower crane to provide lighting. With the development and popularization of the LED technology, the LED tower ceiling lamp is the mainstream product at present. The rated voltage of the LED tower lamp is 220V, 380V power electricity is mainly used on a construction site, and 380V voltage is used for the non-LED tower lamp used in the past, so that a plurality of electricians (namely lamp installers) can naturally use 380V for the LED tower lamp, and the phenomenon that the LED tower lamp is connected to a 380V power supply to cause the driving power supply of the lamp to be burnt out frequently occurs. The damage of the driving power supply caused by misconnection is no longer in the guarantee range, and the guarantee of manufacturers cannot be obtained, so that a user needs to pay extra money to maintain or replace the driving power supply.
In order to avoid misconnection, the inventor specially attaches a label for reminding a warning not to access 380V voltage on the shell of the LED tower ceiling lamp and a power supply line in practice, however, the effect is not good. Therefore, it is necessary to take further measures to effectively protect the tower lamp.
Disclosure of Invention
The invention aims to provide a tower ceiling lamp which can effectively protect against lightning stroke and prevent misconnection. The LED light source module comprises a power supply assembly and an LED light source module, wherein the power supply assembly is used for being connected with a power supply, the power supply assembly comprises a driving module, and the LED light source module is arranged on the output side of the driving module; the power supply assembly also comprises a surge protection module, wherein the surge protection module is arranged at the input side of the driving module; the surge protection module is configured to be in a conducting state to drain the power supply to the ground to prevent the power supply from flowing into the driving module when the connected power supply is higher than a preset voltage threshold, and to be in a high impedance state to allow the power supply to flow into the driving module when the connected power supply is lower than or equal to the preset voltage threshold.
The invention can prevent the voltage higher than the preset voltage threshold from flowing into the driving module and the LED light source module, thereby effectively protecting the driving module and the LED light source module and avoiding the phenomenon that the driving module or the LED light source module is burnt due to the wrong access of the voltage higher than the preset voltage threshold.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and fig. 2, the tower crane lamp capable of resisting lightning stroke and preventing misconnection comprises a power supply assembly for connecting a power supply and an LED light source module 10, wherein the power supply assembly comprises a driving module 20, the LED light source module 10 is arranged on an output side of the driving module 20, and the driving module 20 is configured to drive the LED light source module 10 to light up an LED lamp bead, in this embodiment, the driving module 20 may be implemented by using the prior art;
the power supply module further includes a surge protection module 30, the surge protection module 30 is provided on the input side of the drive module 20, and the surge protection module 30 has an anti-lightning function;
the surge protection module 30 is configured to be in a conducting state to drain the power supply to the ground and prevent the power supply from flowing into the driving module 20 when the connected power supply is higher than a predetermined voltage threshold, and to be in a high impedance state to allow the power supply to flow into the driving module 20 when the connected power supply is lower than or equal to the predetermined voltage threshold.
According to the technical scheme, the voltage higher than the preset voltage threshold can be prevented from flowing into the driving module and the LED light source module, so that the driving module and the LED light source module are effectively protected, and the phenomenon that the driving module or the LED light source module is burnt due to the fact that 380V voltage is connected in a wrong mode is avoided.
The voltage limiting function of the surge protection module is realized by adopting the technology of the existing surge protector, and the description is omitted here.
The function of the existing surge protection module is utilized to realize the voltage limiting function and the repeated use capability. If a tower crane lamp is inadvertently connected to a 380V line, the surge protection module is started to be in a conducting state, and the power supply does not flow to the driving module, so that the tower crane lamp cannot be burnt. After the 220V line is reconnected, the tower crane lamp is safely and naturally lightened.
The technical scheme solves the problem that the 380V line is burnt out due to the mistaken connection of the tower crane lamp for many years, and can reduce the loss of construction and use units.
The preset voltage threshold is lower than or equal to 330V.
In this embodiment, for example, the preset voltage threshold may be set to 330V, 300V, 280V, 220V, or the like.
The power supply assembly further comprises a wrong wiring indicating module for giving out a prompt when the connected power supply is higher than a preset voltage threshold value.
According to the technical scheme, the error wiring indicating module is arranged to timely and accurately send out a prompt signal to an electrician, the electrician does not need to spend a long time to find the reason that the light is not turned on, and correction measures can be timely taken.
The wrong wiring indicating module comprises a primary winding 40, a secondary winding 50, a rectifier bridge 60, an energy storage capacitor 70 and a light emitting diode indicator lamp 80;
one end of the primary winding 40 is connected to the output end of the surge protection module 30, and the other end is grounded;
the secondary winding 50, the rectifier bridge 60 and the energy storage capacitor 70 are connected in sequence;
the primary winding 40 and the secondary winding 50 form a transformer to charge the energy storage capacitor by using the electric energy leaked to the ground when the surge protection module is in a conducting state;
the led indicator lamp 80 is connected to the discharge circuit of the energy storage capacitor 70.
The technical scheme has simple and convenient structure, can fully utilize the leakage current electric energy, and does not need to be additionally arranged as a backup power supply for supplying power to the light-emitting diode indicating lamp.
