Abstract
The utility model provides a high heat-dissipation light-emitting diode (LED) lamp, which comprises a lamp casing body, a circuit board and an LED light source which is arranged on the circuit board. The high heat-dissipation LED lamp is characterized in that a heat-conducting plate used for fixing the circuit board is arranged in the lamp casing body, heat-dissipation space is arranged between the heat-conducting plate and the casing body, and the heat-dissipation space is provided with an air channel communicated with the outside. The high heat-dissipation LED lamp is simple in structure and remarkable in heat-dissipation effect, can improve service life of the LED light source and reduces using cost.
Description
Technical field
The utility model relates to the LED lighting engineering, particularly relates to a kind of LED light fixture with high heat dispersion.
Background technology
Led light source is to be the light source of illuminator with light emitting diode (LED), the LED technology comes from the sixties in 20th century, led light source has efficient height, long characteristics of life-span, its energy conversion efficiency is very high, under the equal illumination, compare, have obvious energy-saving effect with other lighting engineering, only be equivalent to 10% of incandescent lamp as its energy consumption, be equivalent to 50% of fluorescent lamp; And led light source required voltage, electric current are all less, and it is also less to generate heat, and does not have potential safety hazard generally speaking, is the good lighting engineering of a kind of security performance; Led light source can not produce the leakage of materials such as mercury and pollute, and is a kind of light source of environmental protection.
But the life-span of light emitting diode (LED) and usefulness are extremely responsive to its environment temperature, and when temperature surpasses 50 ℃, will significantly decay its service life.
The utility model content
At problems of the prior art, the purpose of this utility model is to provide a kind of LED light fixture with high heat dispersion.
The technical solution of the utility model is as follows:
A kind of high heat radiation LED lamp, comprise lamp casing and circuit board, and be arranged at led light source on the circuit board, it is characterized in that, be provided with the heat-conducting plate of fixing circuit board in the described lamp casing, described heat-conducting plate has radiating surface, has heat-dissipating space between the radiating surface of described heat-conducting plate and the lamp casing, and this heat-dissipating space has and the extraneous air flue that communicates.
Optionally, the radiating surface of described heat-conducting plate is provided with a plurality of thermal troughs.
Optionally, the two ends of described thermal trough perforation heat-conducting plate.
Optionally, described heat-conducting plate is aluminium sheet or aluminium alloy plate.
Technique effect of the present utility model is:
By led light source and circuit board are fixed on the heat-conducting plate, by heat-conducting plate the heat that led light source produces is conducted fast timely, keep the operating ambient temperature of led light source reliable and stable, can guarantee the service life of led light source, accordingly, also can reduce the use cost of LED street lamp.
Description of drawings
Figure 1 shows that structural representation of the present utility model.
Reference numeral lists as follows: 1-housing, 2-heat-conducting plate, 3-thermal trough, 4-through hole, 5-circuit board, 6-LED light source.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Be illustrated in figure 1 as a kind of specific embodiment of the present utility model, as shown in Figure 1, high heat radiation LED lamp comprises LED lamp casing 1 and circuit board 5, is provided with heat-conducting plate 2 in the housing 1, heat-conducting plate can be preferably the aluminium based metal plate for the good material preparation of heat conductivility.
Can be provided with thermal trough 3 on the heat-conducting plate 2, thermal trough 3 can be the circular port groove, also can be the trapezoidal hole groove, or the hole slot of other shape, and a plurality of thermal troughs 3 can be set on the heat-conducting plate 2, to enlarge area of dissipation as much as possible, improves radiating effect.Thermal trough 3 can connect the two ends of heat-conducting plate.
In order further to improve the radiating effect of heat-conducting plate 2, have heat-dissipating space between heat-conducting plate 2 and the housing 1, simultaneously, heat-conducting plate 2 two ends are provided with air flue (for example through hole) 4 and communicate with the external world, so that the air between housing is inside and outside can flow freely, further improve radiating effect.
The technical solution of the utility model can be applied in the various lamp lighting environment, as daily household LED light fixture, or the LED street lamp.
