Technical Field

The embodiment of the invention relates to the technical field of illumination, in particular to a driving circuit and a driving method of an illumination device and the illumination device.

Background

Light Emitting Diodes (LEDs) have the characteristics of low current consumption and long service life. In the technical field of lighting, the popularity and market share of LED lighting devices are increasing, and it is also becoming more common to replace traditional lighting devices with LED lighting devices.

The scheme of replacing the traditional lighting device with the LED lighting device has two types: one solution is that the conventional lighting device is wholly replaced by the LED lighting device, and the electric connection problem does not exist in the scheme, but the whole replacement needs to be installed by punching holes in the ceiling again, so that the problems of time and labor waste exist. The other scheme is that the LED straight tube lamp replaces a traditional lamp tube, and as most of lamp caps of the traditional lamp tube (such as HID and fluorescent lamp) are standard lamp caps, most of lamp caps of the LED straight tube lamp are standard lamp caps, and therefore, the lamp holder of the LED straight tube lamp can be matched with the lamp holder of the traditional lighting device structurally. However, the scheme has the problem of electrical matching, improper treatment even can cause electric shock to people, and the life health of the people is threatened. In addition, in practical applications, besides the situations of energy saving modification and the like, there are other situations that the LED straight lamp needs to be mounted on the lamp holder of the conventional lighting device, such as damage to the LED straight lamp.

In the prior art, in order to solve the safety problem when the LED straight tube lamp is installed, an on-off key is installed at the position, corresponding to the lamp holder, of the lamp holder, and the on-off key is conducted when the lamp holder is clamped into the lamp holder, so that the LED straight tube lamp can be normally used; when the lamp holder is detached, the switch key is turned off, and electric shock can not occur even if a person touches the lamp holder. However, when the LED straight lamp is installed, the user may press the on/off key by mistake, which may cause the on/off key to be in an on state, resulting in an electric shock. Moreover, because a gap exists between the position of the straight LED lamp in direct contact with the lamp holder, the situation that the straight LED lamp is not on due to the fact that the lamp holder of the straight LED lamp is already installed on the lamp holder but the on-off key is not conducted can easily occur. Therefore, the prior art has the problems of poor safety performance and unstable work.

The time for eliminating the vibration is determined by the timing time of the timing module, and the longer the timing time is, the longer the time interval between the lighting device and the vibration elimination is when the lighting device restarts to work.
