TECHNICAL FIELD
[0001] The utility model relates to a lamp control technical field especially relates to a manual light control circuit. BACKGROUND
[0002] In the same place, influenced by time, user, use condition and other factors, there can be different lighting needs, for example, in the bedroom, daytime white light lighting is the basic lighting need, night lighting needs to be more soft compared with daytime lighting, and when reading, watching, the lamp needs to emit other different color temperature and illumination intensity. Facing such needs, the traditional scheme is to set multiple sets of lighting equipment, such as assembling daylight lamp, night light, atmosphere lamp, etc. to correspond to different needs respectively.
[0003] And in reality, multiple sets of lamps obviously increase the purchase cost and construction and maintenance cost, and part of the place does not have the condition of installing multiple sets of lamps, so manufacturers have launched lamps with adjustable brightness and color temperature, which adjust the current and voltage of the lamps through the control circuit, so that the same lamp can emit different brightness of different color temperature. However, in order to adapt to the traditional lamp switch, most lamps are switched in turn by repeatedly turning on and off, assuming that the soft light mode needs to be turned on at night, the high brightness white light mode or even more modes may need to be turned on first, and then gradually switched to the soft light mode. It can be seen that this kind of lamp cannot select the lighting mode when it is turned on, the control logic is complicated, and the service life is significantly shortened under the long-term repeated turning on and off of the switch. In addition to the driving circuit, the additional control circuit also increases the probability of potential failure. UTILITY MODEL CONTENTS

[0027] The output end T2 is electrically connected with the lamp bead LED1, and the output end T3 is electrically connected with the lamp bead LED2
[0028] The sliding input end S is used to connect the adjacent output end T1 and T2, or the output end T2 and T3, or the output end T3 and T4.
[0029] In the embodiment, the sliding input end S has two ports, which are used to simultaneously connect any two adjacent output ends.
[0030] In the embodiment, the output end T1 and T4 are connected with a circuit breaker.
