Description

A kind of controllable type active cool type LED wick

Technical field

The utility model relates to wick, relates in particular to a kind of LED wick of heat radiating type.

Background technology

That traditional incandescent lamp (tengsten lamp) consumes energy is high, the life-span is short; under the overall situation of global resources anxiety; gradually, forbidden producing by national governments; and substituted by electronic energy-saving lamp; although electronic energy-saving lamp good energy-conserving effect; but owing to using the heavy metal element of more contaminated environment, run counter to the trend of environmental protection.

Along with the high speed development of LED technology, LED illumination becomes the only selection of novel green illumination gradually. LED is far superior to traditional lighting product in the aspect of principle of luminosity, energy-saving and environmental protection.

Current LED lamp, is all made up of several LED lamp pearls, just has optic angle degree because LED lamp pearl itself is luminous, adds between adjacent LED lamp pearl and has distance, and the light sending is inhomogeneous, easily occurs the phenomenon of light and shade inequality; In addition the heat dispersion of existing LED lamp is poor, is unsuitable for long-time use.

Utility model content

The purpose of this utility model is to be to provide a kind of controllable type active cool type LED wick, solves one or more in above-mentioned prior art problem.

According to an aspect of the present utility model, a kind of controllable type active cool type LED wick is provided, comprise pipe, two wires and and be arranged at the heat dissipation base of pipe outer side edges by the first connecting plate spiral, heat dissipation base is evenly equipped with multiple LED chips, multiple LED chips form bus, one end of bus is made as positive electrode, and the other end of bus is made as negative electrode, and two wires weld with positive and negative electrode respectively; One end of pipe is provided with blower fan, other end sealing, and projection place of heat dissipation base on pipe is provided with several air vents; Also comprise temperature sensor and controller, temperature sensor is arranged at inside pipe wall, and controller is electrically connected on respectively temperature sensor and blower fan, and controller can be controlled the open and close of blower fan.

In some embodiments: heat dissipation base comprises multiple fin that be arranged in parallel, between each fin, connect by the second connecting plate.

In some embodiments: pipe lateral wall scribbles reflecting coating. Can improve thus overall brightness.

In some embodiments: controller is single-chip microcomputer.

The utility model is by by LED chip spiral setting on the pipe of LED wick, makes the light that sends more even, and cooling fan and controller are installed, in the time that needs dispel the heat, can carry out active and ventilate, temperature with high efficiency, be applicable to high-power, long illumination work, adaptability is good.

Fig. 2 is the sectional view of a kind of controllable type active cool type of the utility model LED wick;

Fig. 3 is the structural representation that a kind of controllable type active cool type of the utility model LED wick arranges air vent.

Detailed description of the invention

Below in conjunction with brief description of the drawings, the utility model is described in further detail.

As Figure 1-3, a kind of controllable type active cool type LED wick, comprises pipe 1, two pieces wires and and is arranged at the heat dissipation base 2 of pipe 1 outer side edges by the first connecting plate 5 spirals. Heat dissipation base 2 comprises multiple fin that be arranged in parallel 21, and in the present embodiment, the quantity of fin 21 is 2, between each fin 21, is welded to connect by the second connecting plate 22. In heat dissipation base 2, outermost fin 21 surfaces are evenly equipped with multiple LED chips 3, and multiple LED chips 3 form bus 4, and one end of bus 4 is made as positive electrode, and the other end of bus 4 is made as negative electrode, and two wires weld with positive and negative electrode respectively.

One end of pipe 1 is provided with blower fan 6, other end sealing, and wherein blower fan 6 is fixedly mounted on the end of pipe 1 by support, and blower fan 6 can discharge the air-flow in pipe 1. Projection place of heat dissipation base 2 on pipe 1 offers several air vents 11. Blower fan 6 can be connected in parallel with bus 4, and in the time that bus 4 is switched on, blower fan 6 is started working, and near hot gas bus 4 passes through in air vent 11 inspiration pipes 1, and discharges, and temperature with high efficiency is applicable to high-power, long illumination work.

Also comprise temperature sensor 7 and controller 8, temperature sensor 7 is fixedly installed on pipe 1 inwall near air vent 11 places, and controller 8 is electrically connected on respectively temperature sensor 7 and blower fan 6, and controller 8 can be controlled the open and close of blower fan 6. Controller 8 is single-chip microcomputer, and controller 8 can design temperature preset value, and temperature sensor 7 can be measured the temperature at air vent 11 places, and sends to controller 8. In the time that the temperature of measuring is more than or equal to temperature preset value, controller 8 is controlled unlatching blower fan 6 and is carried out active heat removal; In the time that the temperature of measuring is less than temperature preset value, controller 8 controls and cuts out blower fan 6. Thus, the heat radiation of control wick that can be intelligent, in the time that temperature is not high, without heat radiation, energy saving.

Manage 1 lateral wall and scribble reflecting coating, reflecting coating can reflect the light of LED chip 3, can improve illuminance.

In sum, the utility model passes through LED chip spiral setting on the pipe of LED wick, make the light that sends more even, and cooling fan and controller are installed, in the time that needs dispel the heat, can carry out active and ventilate, temperature with high efficiency, be applicable to high-power, long illumination work, adaptability is good.

The above is only a kind of embodiment of the present utility model; it should be pointed out that to those skilled in the art, do not departing under the prerequisite of the utility model creation design; can also make some similar distortion and improvement, within these also should be considered as protection domain of the present utility model.
