The specific embodiment
Just as described in the background section, the cost of the heat-sinking capability of adjusting LED road-light light-source module of the prior art is larger, inventor finds, the reason that occurs above-mentioned phenomenon is, structure is formed in one between the radiating fin of LED road-light light-source module and light source installing plate in prior art, when regulating the heat-sinking capability of LED road-light light-source module, can only regulate by the area that redesigns radiating fin and light source installing plate.The LED road-light light-source module of for example 100W is comprised of the light source module of 4 25W, as shown in Figure 2; When the power of LED road-light light-source module changes, as described in the increased power of LED road-light light-source module to 150W, need to increase by the low-power light source module of two 25W, as shown in Figure 3.And increased after two low-power light source modules, the increased power of LED road-light light-source module, need larger area of dissipation, therefore the quantity of the radiating fin on light source installing plate or area also will increase thereupon, the heat that LED road-light light-source produces to shed, and because radiating fin and light source installing plate are structure as a whole, therefore, the overall structure of LED road-light light-source module all needs to increase to original 1.5 times, the all component that is LED road-light light-source module all needs to redesign, make, thereby causes the cost of LED road-light light-source module larger.And if while reducing the power of LED road-light light-source module, also need to redesign and make light source installing plate and radiating fin, to be applicable to low power LED road-light light-source module, can need again larger cost to reequip.
For this reason, inventor proposes a kind of LED heat radiating device of road lamp, comprising:
Light source installing plate, the first surface of described light source installing plate is used for installing LED light source;
Be arranged on the multiple dismountable radiating fin on the second surface that described light source installing plate deviates from described first surface.
From above-mentioned technical scheme, the LED heat radiating device of road lamp that the utility model provides, comprise light source installing plate and be arranged on the multiple dismountable radiating fin on described light source installing plate, because described radiating fin can be installed on described light source installing plate, and after installing, can also disassemble as required, be that described radiating fin and described light source installing plate are not integrative-structures, thereby when regulating the heat-sinking capability of different capacity LED road-light light-source module, only need be according to the difference of the power of LED road-light light-source module, adjusting is installed to the quantity of the radiating fin on described light source installing plate, and without all component of integral replacing LED road-light light-source module, thereby greatly reduce the cost of the heat-sinking capability that regulates LED road-light light-source module.
