Description

  The present invention relates to a kind of valve heat dissipation structure, and more particularly to a valve heat dissipation structure capable of increasing the heat dissipation efficiency.

  Modern tungsten incandescent lamps were successfully researched and developed during the transition from the 19th century to the 20th century, and the inner light emitters were made of tungsten-made filaments. Is very high and can maintain a solid state even at high temperatures, so that the bulb can have a certain life, and the filament does not burn out in a short time and becomes unusable. Actually, the filament temperature of the lit incandescent lamp reaches 3000 degrees Celsius, and the electric lamp generates bright light by the light radiation generated by the hot filament. As a result, the human life is not hindered by the arrival at night, and the light emitted by the incandescent lamp continues many activities at night, whether at work or in life, and offers more possibilities. Expand. It can be said that the incandescent lamp invention has greatly changed the way of life of mankind, and extends the time of activities in many directions and develops it in various ways.

  With the advancement of lighting technology, lighting lamps have been developed, and in the existing lighting lamps, the efficiency of incandescent lamps is the lowest, and the portion that is converted to light energy of the consumed electric energy is reduced from 12% to 18% However, the energy conversion efficiency is quite low, the other parts are dissipated in the form of thermal energy, and most of the energy is wasted. Therefore, with the advancement of science and technology, the technology of light emitting diodes and related peripheral integrated circuit control elements and heat dissipation technologies are maturing more and more, their applications are further diversified, low-efficiency power indicator lamps and mobile phone keyboard light sources To LED backlight modules and general lighting products, it is gradually replacing traditional light sources. Compared with incandescent lamp bulbs, which have a short life and generate heat, light emitting diodes have the advantages of low power consumption, no mercury, no halides, and low carbon dioxide emissions. As people increasingly focus on the agenda for environmental protection and consider various aspects of reducing carbon dioxide and reducing the use of mercury and halides, governments set deadlines to ban the use of incandescent lamps. Promote the use of light emitting diodes.

  The light emitting characteristics of the light emitting diode are in the form of a point light source, and therefore are more elastic in design, and by dispersing the light source, the eyes are not irritating and can be concentrated on a single point or a specific area, The generated color can be made clearer, and the luminous efficiency of the white light LED is currently 70 lm / W or more, which already exceeds 15 lm / W of the incandescent lamp. At present, only 35% of the input power of the light emitting diode is converted into light, and the remaining 65% is converted into heat, and the amount of heat generated is a cause of a decrease in the light emitting efficiency of the light emitting diode. Further, the thermal energy generated by the light emitting diode is accumulated if the heat dissipation mechanism of the entire device is defective, the thermal energy is accumulated and the light emitting diode cannot derive heat, and the life of the light emitting diode is shortened. In general, the life of an LED lamp is 100,000 hours or more, but when the working temperature is 85 ° C. or more, the life is significantly shortened.

  Therefore, when using bulbs including LED bulbs, an increase in the amount of heat is an inevitable result, and heat dissipation is a means to solve this problem. The focus of related technology is how to improve the heat dissipation efficiency of each part. Whether to extend the service life. In addition to the light emission source, the power source driver also generates heat energy, and if the heat radiation of the power source driver is poor, the efficiency of the LED bulb similarly deteriorates and consequently the LED bulb cannot be started. Therefore, if the heat dissipation mechanism of these two parts is bad, and if they affect each other, the temperature will rise for that reason, and the service life of the LED bulb will be lowered, the indoor temperature will be raised, and the user will not be comfortable Therefore, the heat dissipation mechanism is here and is one of the most important issues.

  Almost all of the valve heat dissipation structures currently on the market are fin-type heat dissipation structures, and the fins of this structure extend outward from the center of the main body, hold a space in the center, and a power driver is in the space. Left unattended. However, when the power driver itself is a heating element, and the heat energy generated by the light source is transferred to the fins by heat conduction, the heat completely surrounds the power driver and the heat energy generated by the power driver. The internal temperature becomes excessively high under this effect, leading to the destruction of the electronic components in the power supply driver, for example, the electrolytic capacitor (heat-resistant temperature 105 degrees Celsius, life 8000 hours). It has a severe impact on the life of the driver, and the temperature of the light source does not decrease due to the co-heating effect, which lowers the light emission efficiency, and is therefore a problem caused by damage often formed inside the power driver. This may not be a problem of the light emission performance of the light source itself.

  The fin-type heat dissipation structure can only dissipate the heat energy generated by the light source, the heat dissipation mechanism is not perfect, and the power driver placed in it is a mechanism that dissipates the heat energy generated by it And the heat energy generated by the power supply driver induces a co-heating effect with the heat energy generated by the light source, resulting in damage to the electronic components in the power supply drive and thus affecting the life of the bulb. .

By increasing the area, heat energy can be transmitted quickly to the surrounding environment, accelerating the heat dissipation process, improving the overall heat dissipation mechanism and performance, and extending the service life of the valve.

  The next object of the present invention is to provide a heat dissipation structure for a kind of valve, which uses a power supply connecting portion, and installs a power supply driver in the power supply connecting portion, and the power supply connecting portion includes these Installed at the bottom of the fin, effectively separating the heat radiating case from the power connection portion to maintain a certain distance, and the heat energy generated by the power supply driver in the power connection portion Shall be dissipated through.

  For the above-mentioned purpose, the present invention provides a kind of bulb heat dissipation structure, which includes a heat dissipation case and a plurality of fins, and these fins are provided in an annular shape on the inner wall of the heat dissipation case, When installed on these fins and the light source generates heat energy, the heat energy is transmitted to the heat dissipation case through the fin that the light source directly contacts, and heat dissipation is performed by the heat dissipation case. The process of heat dissipation is accelerated, the thermal energy does not continue to concentrate on the light source, and the light emission efficiency and service life of the light source are both significantly improved.

  Further, the present invention includes a power connection part, a power driver is installed in the power connection part, the power connection part is installed at the bottom of these fins, and the light source and the power connection part are isolated. The heat dissipation case can effectively dissipate heat generated by the power supply driver, thereby extending the life of the power supply driver and thereby extending the life of the valve.

  Further, the heat radiating case of the heat radiating structure further includes a plurality of heat radiating holes, and these heat radiating holes are installed on the surfaces of the heat radiating case and the power supply connecting portion, and the heat radiating efficiency is enhanced by such a structure.

The heat dissipation structure of the present invention improves the shortcomings of the fin type heat dissipation structure, provides a heat dissipation method for the power supply driver, effectively solves the co-heat effect, thus extending the service life of the bulb and emitting light.

Among them, the hole diameter of the first heat radiation hole 111 gradually increases from a bottom portion where the opening is relatively narrow to an upper portion where the opening is relatively wide. However, the hole diameter arrangement of the first heat radiating holes 111 is not limited to the above-described gradual increase method, but is elastically adjusted according to actual needs, or has other hole diameter changes, The hole diameter of the present invention is not limited to this, and is only for explaining the present embodiment.

  Further, the housing portion 23 is further provided. The housing portion 23 is installed at the bottom of the fins 22 and is located inside the heat radiating case 21. The function of the housing portion 23 will be described later.

  3 and 4 are an assembly display diagram and an assembly completion display diagram of a light emitting source and a heat dissipation structure according to another embodiment of the present invention. The bulb presented by the present invention includes a light emitting source 30, which is a substrate 32, which directly contacts the fins 12, and the side of the substrate 32 is the side of the heat dissipation case 11. The power supply connecting portion 34, which is tightly joined to the upper end of the inner wall and is intimately combined with the heat conductive paste or adhesive, is installed in the accommodating portion 13, and the power connecting portion 34 is When the power driver 342 has a hollow body and the power driver 342 is installed therein, and the power driver 342 is installed in the power connection part 34, a heat-conducting adhesive may be interposed, thereby the power driver 342.
