The utility model content

Main purpose of the present utility model is to provide a kind of Waterproof LED driver, is intended to improve water resistance and the thermal conductivity of driver, realizes quick connection the between LED driver and LED load.

The utility model proposes a kind of Waterproof LED driver, comprise the LED drive circuit plate, on described LED drive circuit plate, be coated with a silicon gel layer, outside described silicon gel layer, embedding has heat-conducting silicone grease; Output at described LED drive circuit plate is connected with waterproof plug, the waterproof socket coupling in described waterproof plug and LED load waiting.

Preferably, also comprise a plastic shell, embedding has the described LED drive circuit plate of described heat-conducting silicone grease to be fixed in described plastic shell, and described waterproof plug is arranged on an end of described plastic shell.

Preferably, be provided with the cantilever hooks of the draw-in groove adaptation in some and LED load at the end that described waterproof plug is installed of described plastic shell, the draw-in groove in described cantilever hooks and LED load forms buckle structure.

Preferably, described waterproof plug is arranged on the middle position of an end of described plastic shell, and described cantilever hooks is arranged on the periphery of an end of described plastic shell.

Preferably, at an end of described plastic shell, be provided with an annular groove arranged around described waterproof plug, be provided with adaptive O-ring seal in described annular groove.

The LED drive circuit plate of Waterproof LED driver of the present utility model was coated with one deck silicon gel before encapsulation, the silicon gel have water-fast, anti-ozone, weather-resistant, linear shrinkage ratio low, be easy to the advantages such as perfusion, can in-65～200 ℃ of temperature ranges, keep elasticity for a long time, and there is good electric property and chemical stability, can improve the security performance of LED driver, the components and parts that in the time of can avoiding because of direct encapsulated epoxy resin, epoxy resin cure shrinks on the LED drive circuit plate caused are pulled; Then with heat-conducting silicone grease, the LED drive circuit plate that is coated with the silicon gel is poured into to encapsulation, after heat-conducting silicone grease solidifies, form and there is flexible solid, can be shockproof; The water absorption rate of heat-conducting silicone grease is extremely low, and the water resistance of LED driver is improved; And heat-conducting silicone grease has good thermal conductivity, can be fast the heat on the LED drive circuit plate be derived, thereby can prevent that temperature that the LED drive circuit plate produces because of work from distributing does not go out the temperature rise caused, and extends the service life of LED drive circuit plate.

In addition, output at described LED drive circuit plate is connected with waterproof plug, and the waterproof socket coupling in described waterproof plug and LED load waiting, can be by the quick grafting of waterproof plug and waterproof socket, realize the electric connection of LED driver and LED load, simple to operate; Be provided with the cantilever hooks of the draw-in groove adaptation in some and LED load at the end that described waterproof plug is installed of described plastic shell, draw-in groove in described cantilever hooks and LED load forms buckle structure, can be connected with the buckle of draw-in groove by cantilever hooks, LED driver is quick installed in the LED load.

The specific embodiment

Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Referring to figs. 1 through Fig. 3, one embodiment of Waterproof LED driver of the present utility model is proposed, this Waterproof LED driver comprises plastic shell 104 and is placed in the LED drive circuit plate 101 in this plastic shell 104, be coated with a silicon gel layer 102 on LED drive circuit plate 101, in the outer embedding of silicon gel layer 102, heat-conducting silicone grease 103 arranged.The silicon gel have water-fast, anti-ozone, weather-resistant, linear shrinkage ratio low, be easy to the advantages such as perfusion, can in-65～200 ℃ of temperature ranges, keep elasticity for a long time, and there is good electric property and chemical stability, LED drive circuit plate 101 applied one deck silicon gel before encapsulation, can improve the security performance of LED driver, the components and parts that in the time of can avoiding because of direct encapsulated epoxy resin, epoxy resin cure shrinks on the LED drive circuit plate 101 caused are pulled.Carry out again the perfusion encapsulation of heat-conducting silicone grease 103 after the silicon-coating gel on LED drive circuit plate 101, after heat-conducting silicone grease 103 solidifies, can form and there is flexible solid, can be shockproof; The water absorption rate of heat-conducting silicone grease 103 is extremely low, and the water resistance of LED driver is improved; And, heat-conducting silicone grease 103 has good thermal conductivity, can be fast the heat on LED drive circuit plate 101 be derived, thereby can prevent that temperature that LED drive circuit plate 101 produces because of work from distributing does not go out the temperature rise caused, and extends the service life of LED drive circuit plate 101.
