Description
Technical field
The present invention relates to LED technical field, especially relate to a kind of LED cross-ventilation part.
Background technology
Along with the development of lighting engineering, at present, the operating power of LED can reach higher rate, and LED can send the light of high brightness.This high-power LED lamp has been applied in the lighting apparatus in various large-scale place.But, although this high-powered LED lamp can send high-luminance light, but be limited to photoelectric conversion technique, the photoelectric transformation efficiency of this LED does not still reach 100%, the high-powered LED lamp of the manufacturers produce that some technology are more advanced at present, its electricity conversion also just can reach about 80%, namely in the LED course of work, still has the electric energy of about 20% to be converted to heat energy.If these heat energy can not conduct timely and effectively and distribute from lamp, the service life of LED can be affected greatly.Therefore, all can be equipped with various heat dissipation equipment in existing high-power LED lamp, the heat of its inside is conducted and distributes.
At present, the passive heat radiation structure that the heat dissipation equipment adopted in high-power LED lamp is generally all made up of multiple fin, this radiator structure generally adopts heat by lamp plate conducting on the substrate of radiator, conduct on each fin again, heat is distributed to extraneous radiation processes by thermal-radiating mode by last fin.This radiator structure is not extra high light fixture for power, and radiating effect can meet instructions for use, but for the large-power lamp of super brightness, its radiating efficiency wretched insufficiency.Because the radiating efficiency of passive heat radiation structure is too low, a large amount of heat accumulations on a heat sink, makes the heat on light fixture be difficult to conduct on radiator distribute again, has seriously had influence on the service life of light fixture.
For improving the radiating effect of high-powered LED lamp, technical staff in industry has also made suitable research, as publication number has LED lamp, Authorization Notice No. a kind of LED video display spotlight disclosed in the patent document of CN204611518U of fan heat sink disclosed in the patent application document of CN104879670A, all put forth effort on the heat dissipation problem solving high-powered LED lamp.But, in these schemes, the raising of LED radiating effect depends on radiator fan newly-increased in LED mostly, and this improves production cost and the maintenance difficulty of LED undoubtedly, and the radiating effect realized because of LED self structure does not still improve significantly.
Therefore, be necessary to improve the fitting structure of large-power lamp, improve the radiating effect of large-power lamp self.
Summary of the invention
The object of the present invention is to provide a kind of LED cross-ventilation part, to improve the radiating effect of large-power lamp self.
To achieve these goals, the present invention adopts following technical scheme:
A kind of LED cross-ventilation part, especially, comprises base plate and contiguous block; This contiguous block is connected with base plate, is formed with container cavity in contiguous block; Contiguous block is provided with several air-vents communicated with container cavity; Between adjacent air-vent, this contiguous block is also provided with several steam vents; Base plate is provided with the exhaust via hole corresponding with steam vent, and this exhaust via hole communicates with steam vent; Also being provided with several in container cavity for what guide air-flow direction encloses cover, and this encloses cover and steam vent one_to_one corresponding, wrapped row pore and exhaust via hole.
Principle of the present invention is as follows:
This cross-ventilation part has two air flow channels, and wherein, air-vent and container cavity are interconnected, and forms the first air flow channel of this cross-ventilation part; Steam vent is interconnected with exhaust via hole, with the second air flow channel enclosing cover and form this cross-ventilation part.

For avoiding outside object to enter in container cavity by air-vent, obstruction block can be provided with in air-vent, this obstruction block be formed with several air via holes.Stop block and can stop that outside object enters in container cavity by air-vent, play a part to protect container cavity, be formed at the air via hole stopped on block and then ensure the unimpeded of air-vent.In like manner, in steam vent, obstruction block can be provided with equally, this obstruction block can be formed with several air via holes equally.In addition, the outline of contiguous block can be column, can be provided with a protection edge along on contiguous block circumference contiguous block, for avoiding contiguous block, especially stopping block and damaging because of external force collision.
Base plate can be provided with several ventilative via holes, this ventilative via hole communicates with container cavity.Ventilative via hole communicates with container cavity, and can form the 3rd air flow channel of this cross-ventilation part, the 3rd air flow channel assists the second air flow channel, improves the radiating effect of this cross-ventilation part.
Structure of the present invention is simple, is formed with many air flow channels in cross-ventilation part, can ensure to be arranged on air in the cavity of cross-ventilation part both sides and outside air forms convection current, good heat dissipation effect.
