Abstract
The utility model relates to an LED tube light which comprises a horn-shaped die-casting aluminum light shell, an LED circuit board arranged in the die-casting aluminum light shell, a radiating board arranged above the LED circuit board, an LED power module arranged above the radiating board, and a die-casting aluminum light shell seal cover arranged at the top end of the die-casting aluminum light shell. The LED power module is fixed on the inner side of the die-casting aluminum light shell seal cover, a transparent light reflection board is arranged below the LED circuit board, radiating fins are arranged on the radiating board, radiating strips are arranged on the outer side wall of the die-casting aluminum light shell, and a fixing piece used for fixing the tube light is arranged on the outer side of the die-casting aluminum light shell. According to the LED tube light, radiating is achieved through the mode that the die-casting aluminum light shell provided with the radiating strips is combined with the radiating board, and the radiating performance is better.
Description
Technical field
The utility model relates to field of illuminating lamps, particularly a kind of LED Down lamp.
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, the life-span is long, so obtained very fast development, existing LED Down lamp mainly is mounted on the ceiling as illumination and decorative lamp, existing LED Down lamp, mainly comprise lamp housing, power module, heat sink and lampshade, the heat that produces during the work of LED wiring board mainly is to finish by the heat transmission of heat sink, and radiating effect is relatively poor, therefore, need to make improvements.
Summary of the invention
The purpose of this utility model is the problem for the existing LED Down lamp weak heat-dissipating described in the background technology, and a kind of LED Down lamp that can solve foregoing problems is provided.
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 flaring die casting aluminium lamp housing, be arranged on LED wiring board in the die casting aluminium lamp housing, be arranged on LED wiring board top heat sink, be arranged on the LED power module of heat sink top and be arranged on the die casting aluminium lamp housing capping on die casting aluminium lamp housing top, the LED power module is fixed on the inboard of die casting aluminium lamp housing capping, the below of LED wiring board is provided with transparent reflector, be provided with fin on the heat sink, die casting aluminium lamp housing exterior side wall 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 inside 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.
Be provided with through wires hole in the capping of described die casting aluminium lamp housing, the lead-in wire of LED power module is guided to the outside of LED Down lamp by through wires hole.
Described fixture comprises spring base and the spring leaf that is arranged on die casting aluminium lamp housing both sides.
The advantage of LED Down lamp of the present utility model is: the heat sink of LED Down lamp of the present utility model is arranged on the top of LED wiring board, the heat part that the LED wiring board produces directly is passed to heat sink, simultaneously, because lamp housing and capping all adopt the reasonable metal material of thermal conductivity to make, the heat that produces in the time of can be with the work of LED wiring board and power module is passed to the outside of Down lamp, strengthens the heat dispersion of LED Down lamp.Die casting aluminium lamp housing outer wall arranges heat sink strip, can increase area of dissipation on the one hand, accelerates the heat radiation of LED Down lamp, can play on the other hand the effect of reinforcement, strengthens lamp housing intensity.Below the LED wiring board, transparent reflector is set, can regulates LED light, make its brightness better.
