Description

Air-cooled heat dissipation type L ED down lamp

Technical Field

The utility model belongs to the technical field of the down lamp technique and specifically relates to a forced air cooling heat dissipation type L ED down lamp is related to.

Background

Along with the maturity of L ED technique, L ED down lamp begins to choose for use to the down lamp, L ED down lamp includes the back casing, the face casing, printing opacity face lid, power module and L ED chip, the face casing is fixed in back casing bottom, the middle part of printing opacity face lid fixed in the face casing, L ED chip is fixed in the back casing, the light that L ED chip sent shines through printing opacity face lid, L ED chip needs power module to provide the power for it.

SUMMERY OF THE UTILITY MODEL

To prior art not enough, the utility model aims to provide an air-cooled heat dissipation type L ED down lamp that has good radiating effect, life is high.

In order to achieve the purpose, the utility model provides a scheme is that an air-cooled heat dissipation type L ED down lamp, including the shell with locate the L ED subassembly in the shell, the position that is close to the bottom in the shell is provided with the division board, wherein, the division board separates the inner chamber of shell and forms holding chamber and the heat dissipation wind chamber that is used for holding L ED subassembly, the shaping has the ventiduct that is the heliciform extension with the center of heat dissipation wind chamber to the lateral wall in heat dissipation wind chamber, the center play in heat dissipation wind chamber is provided with a centrifugal fan, set up the air outlet that communicates the shell outside with the ventiduct on the lateral wall in heat dissipation wind chamber, the central point department of the rear end of shell sets up the air intake that communicates the shell outside with the center department in heat dissipation wind chamber, wherein, under centrifugal fan's drive, the outside air of shell is followed the air intake gets into the heat dissipation wind chamber and flows through behind the ventiduct heat transfer from the air outlet.

Further, an air inlet grille and an air outlet grille are respectively arranged on the air inlet and the air outlet.

The utility model discloses the beneficial effect of contrast prior art is, through like this, carry out the heat transfer with the lower air suction heat dissipation wind intracavity of external temperature, and because the ventiduct is the heliciform, make the air current in heat dissipation wind intracavity flow also be the heliciform, effectively increase the dwell time of air in heat dissipation wind intracavity, heat transfer time has been increased promptly, make heat transfer effect and efficiency improved, will hold heat transfer to the heat dissipation wind intracavity that the intracavity produced and take the outside through the air current, L ED down lamp's radiating effect has greatly been improved, thereby L ED down lamp's life has been prolonged.
