Control device of outdoor lamp used in cold region

Abstract

The invention discloses a control device of an outdoor lamp used in a cold region and belongs to the application field of electronic lighting technologies. The control device of the outdoor lamp used in the cold region mainly comprises the mains supply input end, an intelligent controller, a power supply device and a power supply cavity, wherein the intelligent controller and the power supply device are arranged in the power supply cavity. The control device is characterized by further comprising a heating device arranged in the power supply cavity, wherein the heating device comprises a ceramic heating plate and a thermoswitch device, wherein the ceramic heating plate is connected with the thermoswitch device in series and then connected between the mains supply input end and the intelligent controller and is in parallel connection with the intelligent controller. The control device can enable the outdoor lamp to be switched on in the cold region with the temperature lower than -20 DEG C, meanwhile improves the efficiency, reduces ripple factors and ensures the authenticity of data acquired by a management center, the cost of the control device is greatly reduced compared with the cost of a tantalum capacitor, and accordingly the cost of the whole lamp is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic lighting, in particular to a control device for outdoor lamps used in cold regions. Background technique [0002] With the rapid development and application of outdoor lighting technology, the driving power supply is an important part of lighting and display, and its technology is developing rapidly. Especially for power supply devices for outdoor lamps in cold regions, electrolytic capacitors are traditionally used for energy storage and filtering, but in cold regions, especially in cold regions where the temperature is lower than -20°C, the electrolyte in the electrolytic capacitor will Frozen, causing the control device to not work properly, which in turn caused the entire outdoor light fixture to fail to light. [0003] In order to solve the above problems, the market adopts two design schemes for the control device of outdoor lamps used in cold regions: one is to directly remove the capac...

Problems solved by technology

Especially for power supply devices for outdoor lamps in cold regions, electrolytic capacitors are traditionally used for energy storage and filtering, but in cold regions, especially in cold regions where the temperature is lower than -20°C, the electrolyte in the electrolytic capacitor will Frozen so that the controls do not work properly, which in turn prevents the entire outdoor light fixture from being lit

[0003] In order to solve the above problems, the market adopts two design schemes for the control device of outdoor lamps used in cold regions: one is to directly remove the capacitor and inductor, and replace the capacitor and inductor with an electronic ballast. The utilization rate of the control device using this design is very high. Low and very large ripple coefficient will lead to distortion of collected data, and cannot provide real data to the control center for correct management; the second is to use tantalum capacitors instead of electrolytic capacitors. Tantalum capacitors are expensive and have a small capacity, and a lamp The control device needs to use several tantalum capacitors, which is very expensive
