LED heat manages
The LED heat manages:NTC continuously circulates the temperature maintenance LED light the usage is safe
If the LED lamp didn't match enough hot management design, in the process of using in may cause lamp because usually sex hot movement results in life span's downing sharply, producing has to be multifarious and replace break down LED of the harassment of lamp, the serious even may bring about an accident, because of circulate the heat make line or periphery decorated and catch fire combustion!
Develops a stage in the product, can make use of an intelligence type LED light control technique, through monitoring of active type LED the temperature performance of the lamp and whole light source mold piece, simplification equip of hot management work, in the meantime when lamp and whole temperatures rises to a block, the lamp has to lower electricity power and reduce a bright degree of LED exportation, with this promote LED solid light source lamp of usage safety.
Be like LED to absorb a light outer shell considers more simple design form, if the actuator function used by lamp is more focused to the power conversion and LED the module drives, not inside Qian Wen Kong microprocessor with spread a hot processing mold piece, in order to avoid increasing the cost of product raw material piece, the LED lamp can integrate NTC(NegativeTemperatureCoeffient) negative the temperature coefficient ThermistorSensors electricity, is the cost efficiency opposite and higher safety design project.
So-called NTC electricity, it establishes a purpose is by return to the mold piece of monitoring LED lamp temperature through the electronics, through recognize tacitly temperature caution or to drive condition in response to the auto processing, adopt close LED the solid light source mold piece method, promote LED the usage of the lamp safety, the NTC electricity can also lower complications of design in the meantime.
The temperature coefficient that NTC gives or gets an electric shock is very big, therefore can detect and know small temperature variety a performance, is extensively been applied to the related electricity of needing the measurement, control and repair temperature designs in, but NTC electricity at LED light source mold the piece designs in, basically changes for the product peripheral temperature of measurement LED solid light source lamp, as for measurement condition will along with NTC change of electric voltage current conditions, directly measure the temperature of electric voltage and NTC electricity to should relate to.
When NTC and periphery electricity or the whole mold piece temperature promotes, NTC give or get an electric shock of the electric resistance immediately lower, the product can mutually carry on a related safety according to relation according to this control mechanism feedback, for example decrease LED give out light driving of module electric current or directly compulsorily close lamp lighting, at lamp temperature problem improvement after the auto replies lighting appearance, with this safety that acquires a lamp usage.
