Description

Stamping heat sink and manufacturing method thereof

Technical field

The invention relates to a stamping heat sink and a manufacturing method thereof, in particular to a heat dissipating structure suitable for use in an LED bulb and a lamp, thereby accelerating the heat dissipation process. Background technique

Modern tungsten incandescent lamps were successfully developed during the handover period of the 19th and 20th centuries. The illuminators used were filaments made of tungsten wire. This material is characterized by its high melting point and its ability to remain solid at high temperatures. In this way, the bulb has a certain life span, and the filament does not burn out in a short time and cannot be used. In fact, the filament temperature of a lit incandescent lamp is as high as 3000 ° C, and it is because of the glow of the glowing filament that the light is shining brightly. Since then, the coming of the night is no longer a hindrance to people's lives. With the bright light of incandescent light bulbs, all kinds of activities at night, whether at work or in life, can be easily carried out and carried out more. Many possibilities, the invention of incandescent light bulbs can be said to greatly change people's life styles, and extend the period of activities to more aspects, and thus have more different developments.

With the development of lighting technology, all kinds of lighting fixtures have been developed, and among all the lighting fixtures, the efficiency of incandescent bulbs is the lowest, and only 12% of the energy consumed is converted into light energy. - 18%, the energy conversion is quite poor, and the rest is lost in the form of heat, and most of the energy is wasted. Therefore, with the advancement of technology, the technology of light-emitting diodes (LEDs), and related peripheral integrated circuit control components and heat-dissipation technologies are becoming more and more mature, making them more diversified, such as low-power. The power indicator light and the mobile phone keyboard light source, to the LED backlight module and general lighting products, are gradually replacing the traditional commonly used illumination sources. Compared with the incandescent bulbs, the lifespan is short and hot, and the LEDs have low power consumption and no mercury. Halogen-free and low carbon dioxide emissions, for the increasingly important environmental issues, energy conservation; Reduce the use of mercury and the use of 13⁄4 compounds, governments have banned incandescent lamps and extended the promotion of LEDs.

And because the light-emitting diode's light-emitting characteristics are the origin mode, the enemy design is more flexible, and it can make a light source that disperses the light source without glare. It can also be used to concentrate a certain area or a specific area of the light, and the color produced can be more Bright and bright, white LEDs have a luminous efficiency of 70 lm/W, which has exceeded 15 lm/W of incandescent bulbs. However, at present, only 35% of the input power of the LED is converted into light, and the remaining 65% is converted into heat. The above-mentioned heat is the culprit of the reduction of the luminous efficiency of the LED. Furthermore, the thermal energy generated by the LED If the heat dissipation mechanism of the whole device is not good, the accumulation of thermal energy in the LED cannot be immediately released, which will shorten the life of the LED. Generally, the life of the LED lamp is more than 100,000 hours, but if Operating temperatures above 85 °C will greatly reduce life.

Therefore, when the bulb is used, the heat rise is an inevitable result. The heat dissipation is a means to solve this problem, and the related technology focuses on how to improve the heat dissipation efficiency of each part and accelerate the heat dissipation. The service life has been improved. In the LED lamp, there are two heat sources, namely the light source and the power driver. The heat dissipation of both needs to be processed. If the heat dissipation mechanism is not good, the heat generated by the light source is transmitted to the center by heat conduction, and the power driver The generated thermal energy has a common heat effect, and the internal temperature is too high under this effect, so that the electronic components in the power driver are damaged, except that the life of the power driver is seriously affected, and the temperature of the light source cannot be lowered due to the common heat effect. , which causes the luminous efficiency to decrease, which is often caused by damage inside the power driver, and the luminous efficiency of the non-luminous source itself is problematic, and the temperature rises up due to the common heat effect, in addition to the lifetime of the bulb. There is a problem that the indoor temperature is raised and the user is uncomfortable. Therefore, the heat dissipation mechanism is a very important issue here.

In view of the use of various types of light bulbs, if the lamp holder does not have a heat dissipation mechanism, the heat of the light source and the power driver may be difficult to dissipate, thereby causing adverse effects. The present invention provides a stamping heat sink and a manufacturing method thereof. The stamped heat sink is mainly used for heat dissipation of the bulb. The manufacturing method is made by stamping a metal piece, and is integrally formed, and then obtained by folding to obtain a required heat dissipating component, which is placed in the LED lamp cup, and can effectively heat the heat source in the lamp, such as a light source! ^ And the power connection, the generated heat is quickly guided to the lamp cup, and then dissipated through the heat sink of the lamp cup and the lamp cup. Such a structure can not only improve the service life of the lamp, but also for the producer. It's even simpler. Just adjust the stamping die and directly punch out the heat sink of the specified size to directly match all kinds of lamp cups. Summary of the invention

The main object of the present invention is to provide a embossed heat sink for providing a preferred heat dissipation mechanism for a light source.

Or a square, the heat-dissipating leg member is radially disposed on the outer periphery of the base plate, and the screw-shaped hole is distributed on the base plate, wherein the heat-dissipating leg member is punched with a plurality of first leg pieces when punched Traces, according to the requirements of the formation of the corresponding heat sink, according to the different ways of folding, can form a variety of external heat sinks, the heat sink can be simply placed in the lamp cup, if For tightly fixed requirements, the _hii screw hole provides a way to fix the heat sink with screws, and the heat generated by the original reverse can be quickly guided to the stamped heat sink by the screw connection, and then the heat is dissipated and lifted. The heat dissipation efficiency.

Moreover, the heat dissipating leg member of the heat dissipating member may be punched out of a structure of equal length or unequal length as needed. In the preferred embodiment, a plurality of lengths are interposed, and the edge of the heat dissipating leg member is not only a straight line. It can be a special shape such as a curved shape or a zigzag shape. Thus, the surface area of the above-mentioned serrated heat-dissipating leg member is much larger than that of the heat-dissipating leg member at the straight edge, and the contact area with air is increased to accelerate the heat energy and the surrounding air. The efficiency of the exchange, so the design can improve the effect of heat dissipation.

Furthermore, since the heat dissipating member is folded after stamping, the shape of the stamping die can be planned in advance according to the lamp cup or the lamp to be matched, such as the size of the base plate, the length and shape of the heat dissipating leg member, and the screw hole. The configuration and quantity, etc., when you change the design in the future, you only need to replace the stamping die. You can save too many steps and related manufacturing in the production. It is quite flexible and practical for the manufacturer.

In addition, when the present invention is applied to other lamp structures, the design can be changed, and a plurality of heat-dissipating leg members are added to the center of the base plate so that the heat-dissipating leg members are provided inside and outside the base plate, which can be used for the volume of the internal power connection portion.
