Effective and Safe Solution

Proven Technology Ready to Apply

Proven Technology Ready to Apply

 Due to strong and immediate melting power, MeltSmartᵀᴹ is clearly visible all the time. (Comparison with regular signals →)


With patented temperature control feature, deformation or discoloration of lens is prevented.


MeltSmartᵀᴹ contributes to avoid traffic accidents and possible loss of life.

Efficient and Cost Saving

Proven Technology Ready to Apply

Efficient and Cost Saving

Smart, Error-proof configuration → With the dual action of photo and thermal sensors, the MeltSmart™ works only when it is needed. This guarantees economic usage of electricity.


By avoiding possible traffic disturbance and accidents caused by invisible traffic signals in the snow, huge cost is saved.


With MeltSmart™ LED traffic signals, there is less need to send out crews for emergency snow removal which contributes to potential liability savings. Also, this allows maintenance staff to focus on other projects and lowers the cost to state and local government

Key Features of the MeltSmart™

Smart Sensors

Patented Heating Element

Patented Heating Element

Multiple photoelectric and thermal sensors are embedded in the module.


With minimal electricity (0.1W), the sensors detect the snow attached to the surface of the lenses and automatically set the heating element in motion.


Then, by constantly analyzing the condition of the surroundings, the sensors control the power of the heating element (20W ~ 60W) so that only needed amount of power is used to melt the snow. → high energy efficiency maintained


To avoid any false operation, CdS (Cadmium Sulfide) sensor is installed to adjust the sensitivity of sensors during day/night.

Patented Heating Element

Patented Heating Element

Patented Heating Element

 Nichrome heating wire is securely embedded in the polycarbonate lenses of the lamps.


Receiving the signals from the smart sensors, the heating element increases and adjusts the surface temperature of the lenses until the snow completely melts away.


With patented technology, the heating element does not cause any deformation or discoloration of the lens and guarantees the same level of brightness over the time.
