Abstract
The utility model relates to an LED down lamp. The LED down lamp comprises an aluminum die casting lamp housing, an LED circuit board, a heat dissipation plate, an aluminum die casting lamp housing upper cover and an LED power module, wherein the LED circuit board is arranged in the aluminum die casting lamp housing, the LED power module is connected with the LED circuit board through a wire, the LED power module is arranged outside the aluminum die casting lamp housing, the heat dissipation plate is fixed on the LED circuit board, a plurality of sets of cooling fins are arranged on the heat dissipation plate, a transparent light reflecting plate is arranged below the LED circuit board, heat dissipation strips are arranged on the side wall of the outer portion the aluminum die casting lamp housing, and fixing parts which are used for fixing the LED down lamp are arranged outside the aluminum die casting lamp housing. According to the LED down lamp, due to the fact that the LED power module is arranged outside the aluminum die casting lamp housing, when the LED down lamp works, heat produced by the LED power module directly disperses to the external environment, efficiency of heat exchange is high, heat exchange is carried out on heat produced by the LED circuit board through the heat dissipation plate and the aluminum die casting lamp housing, the speed of heat exchange is higher, heat dissipation performance is better, and the situation that the service life of the LED down lamp is prolonged is facilitated.
Description
Technical field
The utility model relates to field of illuminating lamps, and particularly a kind of power module is arranged on the LED Down lamp of lamp housing outside.
Background technology
At present, the application of LED in daily light fixture is more and more, and LED light fixture light efficiency is high, low-power consumption, radiationless, life-span is long, so obtained very fast development, existing LED Down lamp, mainly be mounted on the ceiling as illumination and decorative lamp, existing LED Down lamp mainly comprises lamp housing, power module, heat sink and lampshade, the LED power module is arranged on the inside of lamp housing usually, during work, LED wiring board and LED power module all can produce the larger LED Down lamp of heat, particularly power, during work, more at lamp housing internal heat savings, only rely on lamp housing to come radiating efficiency lower, during excess Temperature, LED power module and LED wiring board easily burn out.
Summary of the invention
The purpose of this utility model is to be arranged in the lamp housing for the power module of the existing LED Down lamp described in the background technology, the heat that produces during work is larger, the problem that power module and LED wiring board easily burn out provides a kind of LED Down lamp that can solve foregoing problems.
The technical scheme that can realize goal of the invention of the present utility model is as follows:
A kind of LED Down lamp, it comprises the die casting aluminium lamp housing, is arranged on LED wiring board, heat sink, the die casting aluminium lamp housing loam cake in the die casting aluminium lamp housing and the LED power module that is connected with the LED wiring board by wire, the LED power module is arranged on the outside of die casting aluminium lamp housing, heat sink is fixed on the top of LED wiring board, be provided with many group fin on the heat sink, the below of LED wiring board is provided with transparent reflector, the exterior side wall of die casting aluminium lamp housing is provided with heat sink strip, and die casting aluminium lamp housing outer setting is useful on the fixture that Down lamp is fixed.
Described LED wiring board is fixed by screws in the madial wall of die casting aluminium lamp housing.
The bottom of described die casting aluminium lamp housing is provided with step surface, and transparent reflector is fixed by screws on this step surface.
For convenient the LED Down lamp is fixed on the ceiling, described fixture comprises spring base and the spring leaf that is arranged on die casting aluminium lamp housing both sides.During use, only spring leaf need to be opened, can be fixed on the ceiling, assemble very convenient.
The advantage of LED Down lamp of the present utility model is: LED Down lamp of the present utility model is arranged on power module the outside of lamp housing, during the work of LED Down lamp, the heat that power module produces can directly spread in the external environment condition, the heat that LED lamp pearl produces is passed to external environment condition by heat sink and die casting aluminium lamp housing heat, the heat sink top directly contacts with die casting aluminium lamp housing loam cake, heat transference efficiency is higher, by above-mentioned improvement, the radiating efficiency of LED Down lamp is improved, prolong the service life of LED Down lamp.
