Description

technical field [0001] The invention relates to the technical field of electric light source lighting, in particular to a solar power source injection lock power synthesis double black light lamp. Background technique [0002] Electronic ballasts in the prior art usually use LC or RC oscillators as the ultraviolet light source of black light lamps, and the oscillation frequency generated is affected by poor stability of temperature changes. The power is unstable and the light intensity drops. Although the structure is simple and the cost is low. However, if the power supply voltage is low, the current of the device must be increased to obtain high-power lighting, so that the power consumption of the oscillating power tube will increase sharply and the temperature will rise too high, resulting in a change in the oscillation frequency. As a result, the power amplitude of the light will be unbalanced as the frequency changes. At the same time, when the large current passes thro...
