Lamp driving circuit and lamp

Abstract

A lamp driving circuit is used for driving a lamp to be started and comprises a transformer and a control module, wherein the transformer comprises a first primary winding, a second primary winding and a secondary winding. In the lamp driving circuit, currents flow through the first primary winding of the transformer, high voltages are sensed on the secondary winding to enable a lamp to be started, and the control module cuts off the power supply of the transformer after starting is completed. The transformer is used for replacing an electronic trigger in a transitional drive to trigger and light the lamp, and therefore the problems that the electronic trigger is short in service life and low in temperature resistance are solved. In addition, the invention further discloses a lamp with the lamp driving circuit.

Description

technical field [0001] The invention relates to the field of lamp protection, in particular to a lamp driving circuit and a lamp. Background technique [0002] At present, with the development of social science and technology, the design and production capabilities of lamps are constantly improving, but the shortcomings of the lamps in the use of heat or heat insulation have not been well resolved, and in some special applications of special lamps , there are strict requirements on the temperature of the lamps. Once the temperature is higher than the set temperature, the lamps are prone to failure or direct damage and cannot be used. The inductive ballast circuit often used in existing lamps uses an electronic trigger to drive the lamp to start. Due to the complex internal structure of the trigger and the short life of electronic components, the life of the trigger is very short, and the temperature resistance of the trigger is very low. Low, can not meet the high temperatu...

Problems solved by technology

[0003] Based on this, it is necessary to provide a lamp driving circuit with long trigger life and high temperature resistance in view of the short life of electronic components and other factors that lead to very short trigger life and low temperature resistance, which cannot meet the high temperature conditions.

[0004] In addition, it is necessary to provide a lamp with long trigger life and high temperature resistance in view of the short life of electronic components and other factors that lead to short trigger life and low temperature resistance, which cannot meet the high temperature conditions.
