Abstract
The utility model relates to lamps, in particular to an LED lamp. The LED lamp comprises a lamp shell, a circuit board assembly, a heat dissipation piece, a base plate, an LED bulb and a reflection cup. The circuit board assembly is arranged in the lamp shell, the heat dissipation piece is arranged below the lamp shell and internally provided with a longitudinal vent hole and a transverse vent hole, the reflection cup is arranged below the heat dissipation piece, the LED bulb and the base plate are both arranged in the reflection cup, the LED bulb is arranged on the base plate, the heat of the heat dissipation piece and the external heat can be exchanged in time through the transverse vent hole and the longitudinal vent hole communicated with each other in the heat dissipation piece, the temperature of the heat dissipation base plate is greatly reduced, it is avoided that due to the fact that the base plate is in the high-temperature state for a long time, the service life of the base plate is shortened, and therefore the service life of the LED lamp is prolonged.
Description
Technical field
The utility model relates to light fixture, particularly relates to a kind of LED light fixture.
Background technology
Due to LED light fixture (Light Emitting Diode, light emitting diode) have low energy consumption, power saving, long service life, volume little, react the advantage such as fast, make LED light fixture progressively replace conventional lamp and be widely used in daily life.
But, LED light fixture also has some defects, the most obvious defect is exactly heat dissipation problem, traditional LED light fixture is that a metal derby is directly set on its substrate, and the two ends that make metal derby are exposed in air, utilize the heat conductivility of metal, heat is passed in air by metal derby, although a part for the heat that this method can produce a part of LED lamp is dispersed in air, but, temperature on substrate is still very high, do not solve thoroughly the heat dissipation problem of LED light fixture, and hot soak condition can shorten the service life of LED light fixture greatly, therefore, be necessary to design a kind of more reasonably structure, thoroughly to solve the heat dissipation problem of LED light fixture.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of LED light fixture, to overcome in prior art because the heat producing in the LED light fixture course of work does not distribute in time, cause working under LED light fixture hot soak condition and reduce the deficiency that exist its service life.
The utility model solves the problems of the technologies described above by the following technical programs:
A LED light fixture, comprises lamp housing, circuit board assemblies, radiating piece, substrate, LED bulb and reflector, and circuit board assemblies is arranged in lamp housing; Radiating piece is arranged on lamp housing below; Reflector is arranged on radiating piece below; LED bulb and substrate are all arranged in reflector, and LED bulb is arranged on substrate; In described radiating piece, be provided with longitudinal passage and horizontal communication hole.
Described longitudinal passage and horizontal communication hole are connected, and horizontal communication hole is in communication with the outside.
Described radiating piece is that aluminum alloy materials manufacture forms.
On the surface of described substrate connection radiating piece, scribble thermal conductive silicon.
Described reflector is formed by pmma material manufacture.
The beneficial effects of the utility model are: by horizontal communication hole and the longitudinal passage being interconnected is set on radiating piece, can timely the heat of radiating piece and the external world be exchanged, the temperature of heat-radiating substrate is reduced greatly, temperature close to outside air, solve the heat dissipation problem of LED light fixture, extended the service life of LED light fixture, simultaneously, on the surface being connected with radiating piece at substrate, smear one deck thermal conductive silicon, be conducive to further heat radiation.

1-lamp housing; 2-circuit board assemblies; 3-radiating piece; 4-substrate; 5-LED lamp; 6-reflector; The longitudinal passage of 7-; 8-horizontal communication hole.
The specific embodiment
In order conveniently to those skilled in the art will recognize that below in conjunction with embodiment and accompanying drawing, the utility model is further described.Embodiment is only to the illustrating of this utility model, and is not to restriction of the present utility model, and the step of not doing in embodiment to illustrate is all prior arts, at this, is not described in detail.
Embodiment mono-
As depicted in figs. 1 and 2, a kind of LED light fixture, comprises lamp housing 1, circuit board assemblies 2, radiating piece 3, substrate 4, LED bulb 5 and reflector 6, and circuit board assemblies 2 is arranged in lamp housing 1; Radiating piece 3 is arranged on lamp housing 1 below; Reflector 6 is arranged on radiating piece 3 belows; LED bulb 5 and substrate 4 are all arranged in reflector 6, and LED bulb 5 is arranged on substrate; In radiating piece 3, be provided with longitudinal passage 7 and horizontal communication hole 8, longitudinally passage 7 and horizontal communication hole 8 are connected, and horizontal communication hole 8 is in communication with the outside.By horizontal communication hole 8 and the longitudinal passage 7 being interconnected is set on radiating piece 3, heat and the external world that can timely radiating piece 3 be come from substrate 4 conduction exchange, the temperature of substrate 4 is reduced greatly, temperature close to outside air, avoided substrate 4 because working and damage under the condition of high temperature for a long time, thereby extended the service life of LED light fixture, simultaneously, on the surface being connected with radiating piece 3 at substrate 4, smear one deck thermal conductive silicon, be conducive to further heat radiation.
Embodiment bis-
As depicted in figs. 1 and 2, according to embodiment mono-, in order to make radiating effect better, described radiating piece 3 forms for aluminum alloy materials manufacture, and will substrate 4 connects on the surface of radiating pieces 3 and scribble thermal conductive silicon; For the light that LED light fixture is sent is evenly soft, reflector is formed with pmma material manufacture.
