All-round light-emitting high-power LED corn-cob-shaped lamp

Abstract

A full-circle luminous high-power LED corn lamp, including a lamp holder, a driving power supply, a lampshade, a radiator, an aluminum substrate, an LED light source, an upper flat cover and a lower flat cover, the lampshade includes an upper lampshade and a lower lampshade, and the radiator includes a heat dissipation body and a heat dissipation The aluminum base plate includes an upper aluminum base plate and a lower aluminum base plate. The upper aluminum base plate and the upper lampshade are respectively installed vertically on the heat sink block, and the lower aluminum base plate and the lower flat cover are horizontally installed on the bottom of the heat sink block. The lamp head is connected with the upper flat cover, and the upper flat cover It is connected with the cooling block, the lower lampshade is connected with the lower flat cover, and the lamp holder is provided with cooling holes. When the LED light source of the present invention is working, it can emit light around the space at an angle of more than 300 degrees, which is suitable for use in more fields. It can also take a large amount of heat energy generated by the LED light source inside the lamp out of the lamp in time, and reduce the work of the lamp and the LED light source in a timely manner. Temperature, easy installation and maintenance, can save working hours to the greatest extent, prolong the service life of LED lamps, improve the cost performance of LED lamps, and is conducive to the promotion and use of LED lamps.

Description

Technical field [0001] The invention belongs to the technical field of lamps, and specifically refers to a full-circle luminous high-power LED corn lamp. Background technique [0002] Where there is light, there is human civilization. In ancient times, people generally used kerosene lamps. After entering modern times, people began to use electric lamps, such as tungsten lamps, LED lamps, etc. Although the traditional tungsten lamp has a large light-emitting surface, figure 1 As shown, but due to the shortcomings of low power, energy consumption, short life, etc. have been eliminated; LED lights are widely used in homes, hotels, schools, hospitals, factories and other places because of their advantages of energy saving, environmental protection, and long life. Including LED bulb lights, LED corn lights, etc., LED bulb lights and LED corn lights are a kind of LED lights, named after their shapes. [0003] At present, because the installation direction of the LED light source is the...

Problems solved by technology

[0003] At present, due to the installation direction of the LED light source is the bottom front of the existing LED bulb lamps, it is determined that the light divergence of the LED light source can only diverge in the same direction, and the other directions have different degrees of dead angle of light. figure 2 As shown, the space cannot be illuminated in all directions, that is, the full-circle lighting of more than 300 degrees cannot be achieved, and the use of places is limited, which is not conducive to widespread promotion; moreover, when the power of LED bulb lamps increases, the size of the lamps also increases. Large, so that the corresponding heat dissipation area is required to solve the high-power ultra-high heat energy. According to the current commonly used supporting lamps, the diameter is about 80mm. After exceeding this range, the installation of LED bulb lamps will be greatly restricted, which is also unfavorable for products. The promotion, the power hour size is correspondingly smaller, but can not provide high-brightness lighting, there are design drawbacks

[0004] At present, some LED corn lamp covers use glass wool tubes, such as attached image 3 As shown, because the glass capillary is transparent glass, it is fragile, which is equivalent to the direct exposure of the LED light source, which will produce great glare, cause light pollution, and is not conducive to the promotion of products; some LED corn lights are also due to the installation of LED light sources. Direction problem, the LED light source is installed on the side, which determines that the divergence direction of the LED light source light can only diverge in four directions. There are shadow areas on the top and bottom of the product, which cannot illuminate the space in all directions, and also cannot achieve a full range of more than 300 degrees. Zhou Luminescence is also limited in places of use, which is not conducive to widespread promotion; in addition, due to poor heat dissipation of the LED corn lamps on the market, not only the power of the lamps is greatly limited, and high-power production cannot be performed, but at the same time, due to the limited power, the luminous flux It is also limited and cannot meet the lighting needs of large spaces. Moreover, the LED light source is prone to extremely fast light decay when it is lit, which seriously affects the service life of LED lighting products. In addition, the existing LED corn lights have unreasonable structural design, which leads to installation , troublesome disassembly, increased business costs
