Description

A kind of spherical LED lamp core of controllable type active heat removal

Technical field

The utility model relates to wick, particularly relates to a kind of LED lamp of heat radiating type.

Background technology

Traditional incandescent lamp (tengsten lamp) consume energy 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 products in the aspect of principle of luminosity, energy-saving and environmental protection.

Current LED, is all made up of several LED lamp bead, and because the luminescence of LED lamp bead own just has angular, add between adjacent LED lamp pearl and there is distance, the light sent is uneven, easily occurs the phenomenon of light and shade inequality; In addition the heat dispersion of existing LED is poor, is unsuitable for long-time use.

Utility model content

The purpose of this utility model is the spherical LED lamp core being to provide a kind of controllable type active heat removal, solves one or more in above-mentioned prior art problem.

According to an aspect of the present utility model, a kind of spherical LED lamp core of controllable type active heat removal is provided, comprise pillar and hollow ball, pillar inserts spheroid, the end of pillar insertion spheroid is positioned at the centre of sphere place of spheroid, sphere inner wall inserts the end in spheroid by multiple heat sink strip connecting struts, and spherome surface is evenly provided with multiple louvre and LED; Pillar boring, pillar inserts the one end open in spheroid, and the other end is closed, and the sidewall of pillar offers gas outlet, is provided with blower fan in gas outlet; Also comprise temperature sensor and controller, temperature sensor is arranged at spheroid outer wall, and controller is arranged at the outer wall of pillar, and controller is electrically connected on temperature sensor and blower fan respectively, and controller can control the open and close of blower fan.

In some embodiments: every four louvres all assume diamond in shape distribution, every four LED all assume diamond in shape distribution, and each LED is all positioned at the center of four louvres of the distribution that assumes diamond in shape.

In some embodiments: spheroid lateral wall scribbles reflecting coating.

In some embodiments: controller is single-chip microcomputer.

The utility model is by being evenly arranged on the surface of spheroid by LED, make the light that sends evenly, and ball interior is provided with fin, can dispel the heat, cooling fan and controller are installed in addition, when needs dispel the heat, active can be carried out ventilate, temperature with high efficiency, be applicable to high-power, long illumination work, adaptability is good, improves the life-span of wick.

Accompanying drawing explanation

Fig. 1 is the structural representation of the spherical LED lamp core of a kind of controllable type active heat removal of the utility model;

Fig. 2 is the enlarged drawing of the A of Fig. 1.

Detailed description of the invention

Illustrate below in conjunction with accompanying drawing, the utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of spherical LED lamp core of controllable type active heat removal, comprise pillar 1 and hollow ball 2, pillar 1 inserts in spheroid 2, the end that pillar 1 inserts spheroid 2 is positioned at the centre of sphere place of spheroid 2, spheroid 2 inwall inserts the end in spheroid 2 by multiple heat sink strip 3 connecting struts 1, the two ends of each heat sink strip 3 all with spheroid 2 inwall, the sidewall weld of pillar 1 near end.Spheroid 2 surface uniform is provided with multiple louvre 4 and LED 5.Spheroid 2 lateral wall scribbles reflecting coating, thereby, it is possible to by the light reflection of LED 5, improves the illuminance of wick.

Pillar 1 boring, pillar 1 inserts the one end open in spheroid 2, and the other end is closed, and the sidewall of pillar 1 offers gas outlet 11, and gas outlet 11, near the blind end of pillar 1, is provided with blower fan 6 in gas outlet 11, and blower fan 6 can by support installing in gas outlet 11.Blower fan 6 can be in parallel with LED 5, and when LED 5 is energized, blower fan 6 is started working, and the hot gas near LED 5 by louvre 4 inspiration pillar 1, and discharges, 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 spheroid 2 outer wall near louvre 4 place, controller 8 is bolted the outer wall being installed on pillar 1, controller 8 is electrically connected on temperature sensor 7 and blower fan 6 respectively, and controller 8 can control 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 measure the temperature at air vent 11 place, and sends to controller 8.When the temperature measured is more than or equal to temperature preset value, controller 8 controls to open blower fan 6 and carries out active heat removal; When the temperature measured is less than temperature preset value, controller 8 controls to cut out blower fan 6.Thus, the heat radiation of control wick that can be intelligent, when temperature is not high, without the need to heat radiation, energy saving.

Wherein, every four louvres 4 all assume diamond in shape distribution, and every four LED 5 all assume diamond in shape distribution, and each LED 5 is all positioned at the center of four louvres 4 of the distribution that assumes diamond in shape, thereby, it is possible to improve radiating effect.

In sum, the utility model by LED being evenly arranged on the surface of spheroid, make the light that sends evenly, and ball interior is provided with fin, can dispel the heat, cooling fan and controller are installed in addition, when needs dispel the heat, active can be carried out and ventilate, temperature with high efficiency, be applicable to high-power, long illumination work, adaptability is good, improves the life-span of wick.

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, under the prerequisite not departing from the utility model creation design; can also make some similar distortion and improvement, these also should be considered as within protection domain of the present utility model.
