Abstract
The utility model discloses a heat conduction pipe type high-power LED lamp which comprises an integrated board and a control circuit. LED beads are evenly arranged on the front side of the integrated board, a tubular heat dissipation device is arranged on the rear side of the integrated board and composed of multiple heat dissipation pipes, one end of an end opening of each heat dissipation pipe is upward, and the other end of the end opening of each heat dissipation pipe is downward. The heat conduction pipe type large-power LED lamp is simple in structure, low in manufacturing cost, capable of achieving the effect of quick heat dissipation by adopting the tubular heat dissipation device through the principle that warm air raises and cold air sinks, and capable of effectively solving the problems that an existing high-power LED lamp is slow and uneven in heat dissipation, and has the advantages of being quick in heat dissipation, long in service life, and friendly to environment, and saving energy.
Description
Technical field
The utility model belongs to lighting technical field, relates to a kind of light fixture, specifically a kind of heat pipe type high-power LED lamp.
Background technology
Present Global expanding economy, more and more highlights shortage of resources and problem of environmental pollution, and global energy and environmental protection pressure are increasing.Therefore, the energy-conserving and environment-protective consciousness of countries in the world just progressively strengthens, and energy-saving and emission-reduction, environmental protection have become the main flow trend of Vehicles Collected from Market and industrial development environment.The concept that first EPA proposed to implement " green illumination " and advanced " Green Lighting Project " in January, 1991, obtain very soon the support of the United Nations and the attention of many developed countries and developing country, actively take corresponding policy and technical measures, advance enforcement and the development of Green Lighting Project, in this process, LED is introduced into illumination application as revolutionary technological innovation.LED light fixture not only has good illuminating effect, and has possessed the features such as energy-saving and environmental protection, the life-span is long, use voltage is low, is deeply subject to liking of broad masses.
Along with social development and science and technology are constantly progressive, the development of LED Lighting Industry has in recent years obtained the development of advancing by leaps and bounds, but, as the LED lamp of cold light source, in luminous, also there is heat to follow, the heat energy of its generation all concentrates on single point, as heat radiation not in time, be easy to cause parts Yin Gaore, high electric current to occur punch through damage, and assembly is for a long time in high warm, also can allow be affected its service life, thereby increase use cost.
At present, radiating mode for LED lamp mainly adopts finned heat abstractor, utilize plate-shaped fin to absorb heat, heat radiation, realize the object to the heat radiation of LED lamp, but finned heat abstractor is taken away heat by air after contacting with air by fin in the time of heat radiation and is dispelled the heat, but because fin heat radiation is the heat radiation of opening formula, the thermal current producing after being heated can produce turbulent flow with extraneous air in fin interval, radiating rate is slow, weak effect, can only be applicable to low power LED lamp, and in road lighting, the aspects such as marine fishing operation, can not reach good result of use, LED lamp circuit board arises at the historic moment thus, by plurality of LEDs lamp pearl is installed at circuit board, its power is increased substantially, increase illuminating effect, but on circuit board, also can produce larger heat, adopt conventional chip heat abstractor, heat can not be distributed in time, cause light fixture to dispel the heat not in time, occur that assembly is overheated, light fixture is burnt out or the problem such as reduction in service life, and LED is temperature sensor, in the time of temperature rise, its luminous efficiency sharply declines.
Utility model content
The purpose of this utility model is to provide a kind of heat pipe type high-power LED lamp for the deficiencies in the prior art, the principle of utilizing thermal current rising cold airflow to sink, adopt tubulose heat abstractor, can realize the effect of quick heat radiating, effectively solve that the heat radiation of existing LED large-power lamp is slow, heat radiation uneven with etc. problem, there is the features such as simple in structure, cost of manufacture is low, long service life.
The technical scheme that the utility model adopts:
A kind of heat pipe type high-power LED lamp, comprise circuit board and control circuit, plurality of LEDs lamp pearl is evenly set in circuit board front side, at the rear side of circuit board, tubular type heat abstractor is set, described tubular type heat abstractor is made up of several evenly distributed radiating tubes, radiating tube is designed to straight-through structure, and upward, the other end down in its mouth of pipe one end.When heat radiation, the heat of sending of LED lamp pearl conducts to radiating tube by circuit board, after absorption of air heat in radiating tube, form thermal air current rising and walk heat by upper end mouth of pipe elution band, flowed into by the lower end mouth of pipe with stylish cold air, carry out the heat absorption of a new round, so circulation, thus reach the effect of quick heat radiating.
The cross section of described radiating tube is square, increases the contact-making surface of radiating tube and circuit board, is conducive to conduct fast heat.
The utility model is simple in structure, cost of manufacture is low, the principle of utilizing thermal current rising cold airflow to sink, adopt tubulose heat abstractor, can realize the effect of quick heat radiating, effectively solve that the heat radiation of existing LED large-power lamp is slow, heat radiation uneven with etc. problem, there is the features such as rapid heat dissipation, life-span length, energy-conserving and environment-protective.

Detailed description of the invention
Below in conjunction with accompanying drawing with by embodiment, the utility model is described in further detail, but not as restriction of the present utility model.
Heat pipe type high-power LED lamp provided by the utility model, comprises circuit board 1 and control circuit, and in the structure shown in Fig. 1, described circuit board 1 is made for aluminum, can conduct fast heat; In circuit board 1 front side, plurality of LEDs lamp pearl 3 is evenly set, can reach better illuminating effect, at the rear side of circuit board 1, tubular type heat abstractor is set, tubular type heat abstractor is made up of several evenly distributed radiating tubes 2, and its mouth of pipe one end upward, the other end down, can vertically arrange or be obliquely installed, the cross section of radiating tube 2 be square, can increase the contact-making surface of radiating tube 2 and circuit board 1, be conducive to conduct fast heat, radiating tube 2 is designed to straight-through structure.When heat radiation, the heat of sending of LED lamp pearl 3 conducts to radiating tube 2 by circuit board 1, after absorption of air heat in radiating tube 2, form thermal air current and walk heat by upper end mouth of pipe elution band, flowed into by the lower end mouth of pipe with stylish cold air, carry out the heat absorption of a new round, so circulation, thus reach the effect of quick heat radiating.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
