Abstract
The utility model discloses a light-emitting diode (LED) lamp which comprises a lampshade, an aluminum substrate, an LED bead and a radiator. The LED bead is installed on the front face of the aluminum substrate and covered by the lampshade. The radiator makes contact with the back face of the aluminum substrate and is a metal water tank. Cooling fins are arranged between the upper bottom face and the lower bottom face of the metal water tank. Each cooling fin protrudes out of the upper bottom face. A through hole is formed in the upper bottom face of the metal water tank. Due to the fact that the radiator with high heat dissipating performance of the LED lamp is in a mode of the metal water tank and the cooling fins, the metal water tank is filled with water, the specific heat capacity of the water is large, temperature increase speed is low after the water absorbs heat, and temperature increase speed of the aluminum substrate is lowered. Meanwhile, the cooling fins are arranged in the metal water tank, so that the heat is dissipated rapidly and the service life of the LED lamp is effectively prolonged.
Description
Technical field
The utility model relates to the LED lighting field, relates in particular to a kind of slow LED lamp of aluminium base programming rate that makes.
Background technology
The LED lamp is the lighting source of new generation behind compact fluorescent lamp.Compare common energy-saving lamp, the environmental protection of LED lamp is not mercurous, recyclable recycling, power is little, high light efficiency, the long-life, namely open namely bright, anti-frequent switch, light decay is little, rich color, tunable optical, change is abundant.Heat radiation for the LED lamp is very important: be cold light source if emphasize LED simply, do not need heat radiation, that is individual mistake completely, before the led chip of also not developing real low heating, LED does not add the high-quality radiator, and its life-span may be also far away from existing common energy-saving lamp so, because light decay is during to initial luminous flux 70%, just meaned the end of a period of LED electricity-saving lamp life-span, therefore, the life-span, long LED lamp must be carried out heat radiation.
The utility model content
It is slow with a kind of aluminium base programming rate that makes that the utility model provides, the LED lamp of long service life.To achieve these goals, the solution that the utility model proposes is: a kind of LED lamp comprises lampshade, aluminium base, LED lamp pearl and radiator; Described LED lamp pearl is installed in the positive of described aluminium base and covers in the described lampshade, and described radiator contacts with the back side of aluminium base; Described radiator is a metal water tank, is provided with radiated rib between the upper bottom surface of this metal water tank and the bottom surface, and this radiated rib protrudes from upper bottom surface; The upper bottom surface of this metal water tank is provided with through hole.
Wherein, described radiated rib is a helical form fin and gapped with the sidewall of described metal water tank.
Wherein, the upper end of the sidewall of described metal water tank is provided with a water inlet, and the lower end of the sidewall of metal water tank is provided with a delivery port, and water inlet and delivery port just are provided with valve.
The beneficial effects of the utility model are: the radiator that is different from the LED lamp of prior art all is the form of sheet metal, the radiator of the LED lamp of high heat radiation of the present utility model is the form of a metal water tank and radiated rib, in metal water tank, fill with water, specific heat of water holds big, it is slow to inhale temperature back programming rate, reduces the speed that aluminium base heats up, and is provided with radiated rib in the water tank simultaneously, can fast heat be dissipated, effectively prolong the service life of LED lamp.

See also Fig. 1 and Fig. 2, a kind of LED lamp of present embodiment comprises lampshade 5, aluminium base 3, LED lamp pearl 4 and radiator; Described LED lamp pearl 4 is installed in the positive of described aluminium base 3 and covers in the described lampshade 5, and described radiator contacts with the back side of aluminium base 3; Described radiator is a metal water tank 1, is provided with radiated rib 2 between the upper bottom surface of this metal water tank 1 and the bottom surface, and this radiated rib 2 protrudes from upper bottom surface; The upper bottom surface of this metal water tank 1 is provided with through hole 8, generally all can be furnished with a piston, when this LED is not installed, with piston through hole is blocked, and can open piston after installation, is used for exhaust and uses.
The radiator of the LED lamp of high heat radiation of the present utility model is the form of a metal water tank 1 and radiated rib 2, in metal water tank 1, fill with water, specific heat of water holds big, it is slow to inhale temperature back programming rate, reduce the speed that aluminium base heats up, be provided with radiated rib 2 in the metal water tank 1 simultaneously, can fast heat be dissipated, effectively prolong the service life of LED lamp.
In the present embodiment, described radiated rib 2 is a helical form fin and gapped with the sidewall of described metal water tank 1, and can make the water in the water tank like this is to be communicated with.Further, the upper end of the sidewall of described metal water tank 1 is provided with a water inlet 6, and the lower end of the sidewall of metal water tank is provided with a delivery port 7, and water inlet 6 and delivery port 7 are equipped with valve, is convenient for changing the water in the metal water tank 1 like this.
In the above-described embodiments, also can inject other liquid in the described metal water tank 1.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
