Accompanying drawing explanation

Fig. 1 is circuit theory diagrams of the present invention.

The specific embodiment

Below with reference to accompanying drawing, technical scheme of the present invention is elaborated.

As shown in Figure 1, the invention provides a kind of light fixture, the satiable lighting power of this light fixture is that the lamp pearl that m single power is p is thrown light on simultaneously, i.e. (p*m), and wherein, m is natural number, p>0; The present invention includes the lighting sub loop that controller is identical with n bar, n is natural number, and n>m, why all lighting sub loops rear connection external power source parallel with one another, be designed to parallel connection by all lighting sub loops but not series connection is mainly to consider that realizing each lighting sub loop works alone, be independent of each other, while preventing wherein a lighting sub loop fault, remaining lighting sub loop is impacted, thereby cause integral body to scrap; Wherein, every lighting sub loop includes lamp pearl and the switch (can adopt relay) of mutual series connection, the power of each lamp pearl is all made as p, each lamp pearl all has unique ID, and all lamp pearls are all connected with controller by holding wire, and when this lighting sub loop energising, the ID of the lamp pearl on this lighting sub loop is sent to controller; Described controller is according to the quantity of the ID receiving, and whether the lighting sub loop that judgement is now normally devoted oneself to work has met lighting power, and controls accordingly the break-make of switch in each lighting sub loop, makes to have the illumination of m bar lighting sub loop simultaneously.

Based on aforementioned structure, the present invention also provides a kind of control method of light fixture, comprises the steps:

(1) for light fixture is connected external power source, as access civil power or connection battery; When connecting external power source, the original state of each switch can be set arbitrarily, as all switches are all set as to off-state, closed at the switch of just being controlled in m bar lighting sub loop by controller after connecting external power source, also the switch that can first control by controller before connecting external power source in m bar lighting sub loop is closed, more the original state of each switch can be set as to closure state (as the original state of dispatching from the factory), after connecting external power source, adjust again;

(2) now there is part switch closed, if the lamp pearl that this closed switch is corresponding is normally worked, can self ID be sent into controller by holding wire, if cisco unity malfunction, holding wire cannot transmit ID, and the present invention utilizes this principle just, by controller, calculated the number x of the current ID receiving, also be the number of the lighting sub loop of current illumination input, known x is natural number certainly, and x is less than or equal to n; X and m are compared:

If 1. x=m, illustrates that the lighting sub loop of m bar switch closure now, all in normal operating conditions, meets lighting power, keep each switch current state constant;

If 2. x<m, illustrate in the m bar lighting sub loop of switch closure now and only have the normal illumination of x lamp pearl, in order to meet lighting power, need in remaining (n-m) bar lighting sub loop, choose arbitrarily (m-x) bar lighting sub loop, and the switch of controlling in this (m-x) bar lighting sub loop of choosing is closed, if the number of the ID that this Time Controller receives is still less than m, be illustrated in this (m-x) bar lighting sub loop of choosing and still have trouble light pearl, need to continue to choose arbitrarily switch closure in remaining lighting sub loop, until the ID number that controller receives is m, now lighting power is (p*m), meet the requirements,

If controller is controlled the ID that certain switch closure is not but received the corresponding lamp pearl of this switch, represent that this lamp pearl breaks down, controller is stored this ID, and is labeled as trouble light pearl, can comprehend the lighting sub loop at this ID place in subsequent control again.

If 3. x>m, the corresponding aforementioned switches original state of dispatching from the factory is the situation of closure state, now need to think to choose arbitrarily in this x bar lighting sub loop (x-m) bar lighting sub loop, and the switch of controlling in this (x-m) bar lighting sub loop of choosing disconnects.

Above embodiment only, for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought proposing according to the present invention, and any change of doing on technical scheme basis, within all falling into protection domain of the present invention.
