Background

With the development of the landscape market, high-power and high-protection-level lamps become indispensable lighting facilities in large-scale landscape projects, the outdoor environment is greatly improved, and the lighting requirements and the attractive requirements are met.

When a high-power lamp is used, the bulb often emits high temperature of hundreds or even thousands of degrees centigrade, and in order to solve the problem of heat dissipation, the external fan is generally added to the lamp to actively dissipate heat, but when the external fan breaks down, the heat dissipation requirement of the lamp cannot be met, and the bulb is easily damaged by high temperature. Therefore, a control method for a lamp is needed to prevent the lamp from being damaged by high temperature when a fan fails.

Disclosure of Invention

The invention aims to provide a lamp control method and a lamp, the lamp control method can intelligently control the running states of a fan and the lamp through monitoring of a temperature sensor, and the lamp is prevented from being damaged by high temperature when the fan breaks down.

The technical scheme is as follows:

the control method of the lamp comprises the following steps: receiving a starting signal, and starting the lamp to run; the first sensor detects the temperature of an external environment, acquires an external temperature signal and sends the external temperature signal to the controller; the second sensor detects the temperature at the air inlet of the light source cooling fan, acquires an internal temperature signal and sends the internal temperature signal to the controller; the controller receives the external temperature signal and the internal temperature signal, and determines whether to switch the working mode of the lamp or not according to the external temperature signal and the internal temperature signal; and determining whether the working state of the external fan is detected or not according to the working mode of the lamp, and adjusting the working state of the light source.

The lamp receives the opening signal, after the lamp starts to operate, the first sensor detects the temperature of the external environment, the external temperature signal is acquired and sent to the controller, meanwhile, the second sensor detects the temperature of the air inlet of the light source cooling fan, the internal temperature signal is acquired and sent to the controller, the controller receives the external temperature signal and the internal temperature signal, according to the external temperature signal and the internal temperature signal, whether the working mode of the lamp is switched or not is determined, according to the working mode of the lamp, whether the working state of the external fan is detected or not is determined, and the working state of the light source is adjusted. According to the control method of the lamp, the running states of the fan and the lamp are intelligently controlled through monitoring of the temperature sensor, and the lamp is prevented from being damaged by high temperature when the fan breaks down.

And when the external temperature is in the first temperature range and the internal temperature is lower than the safe temperature, switching to the freezing mode, and starting to operate the light source. When the environment is at the subzero low temperature, the phenomenon of icing easily occurs to the external fan of the lamp, the blades can not rotate to work due to being frozen, tests prove that when the external environment is at the subzero low temperature, the external fan of the lamp does not need to work, the cast aluminum shell and the radiator of the lamp can effectively conduct and dissipate the temperature inside the lamp, therefore, the working state of the fan does not need to be detected, the light source can start to run, the passive heat dissipation of the lamp is fully utilized according to the change of the external environment temperature, the lamp is prevented from being damaged by high temperature, and meanwhile, the energy-saving effect is achieved.

And when the external temperature is in the second temperature range and the internal temperature is lower than the safe temperature, switching to a low-temperature mode, and starting to operate the light source. Under the low temperature mode, when the phenomenon of freezing exists in outside fan, with freezing the mode the same, need not to detect the operating condition of outside fan, the light source can begin to operate, makes full use of lamps and lanterns self passive heat dissipation according to the change of external environment temperature, has energy-conserving effect when preventing that high temperature from damaging lamps and lanterns.

Under the normal temperature mode, the external fan is not frozen, the working state of the external fan is directly detected, and when the external fan is detected to be in fault, the light source is turned off for safety protection; when the normal work of the external fan is detected, the light source starts to operate, the monitoring of the external fan and the working state of the light source are adjusted through the monitoring of the temperature sensor, and the influence on the material cost and the production cost is small.

The first temperature range is lower than a second temperature range, the second temperature range is lower than a third temperature range, and the unfreezing temperature is lower than a safe temperature. In the first temperature range, the external fan can generate icing phenomenon and can not be unfrozen along with the gradual rise of the internal temperature; in a second temperature range, the external fan can generate icing phenomenon and can unfreeze along with the gradual rise of the internal temperature; in a third temperature range, the external fan cannot be frozen; the temperature range is divided according to the influence of external environment temperature to outside fan, corresponds the mode of temperature range setting lamps and lanterns, carries out intelligent management and control, prevents that high temperature from damaging lamps and lanterns, has certain energy-conserving effect.
