The invention provides a method for identifying the power specification of a high-voltage sodium lamp. The method comprises the following steps that an electronic ballast starts to be powered on and work, the electronic ballast outputs constant power and starts timing, whether a first set time reaches or not is judged, if yes, the next step is executed, if not, waiting continues and the step is judged, the electronic ballast is made to work in a set frequency point and a second set time is delayed, the output power of the electronic ballast is measured, the type of high-voltage sodium lamp is determined according to the magnitude of the output power, and the corresponding power specification is output according to the type of the high-voltage sodium lamp. The invention further provides a device for identifying power specification of the high-voltage sodium lamp. The method and device for identifying power specification of the high-voltage sodium lamp have the advantages of preventing the high-voltage sodium lamp from being easily destroyed and enabling the high-voltage sodium lamp to be safe.
Description
technical field [0001] The invention relates to the field of electronic ballasts, in particular to a method and device for identifying power specifications of high-pressure sodium lamps. Background technique [0002] In the prior art, the electronic ballast used for plant lighting is the most widely used 1000W gear dimming type. Many users will use a 1000W ballast to connect a 1000W high-pressure sodium lamp in the 1000W gear, a 600W high-pressure sodium lamp in the 600W gear, and a 400W high-pressure sodium lamp in the 400W gear. When the gear set by the user does not match the specifications of the connected high-pressure sodium lamp, for example: when a high-power gear is used to connect a low-power high-pressure sodium lamp, the high-pressure sodium lamp will be damaged soon, causing economic losses and extremely serious Big security risks, resulting in insecurity. Contents of the invention [0003] The technical problem to be solved by the present invention is to pr...
