一种LED散热器及装有该散热器的LED灯泡A kind of LED radiator and LED light bulb equipped with the radiator

技术领域 technical field

本实用新型涉及LED照明领域，特别涉及一种LED散热器及装有该散热器的LED灯泡。 The utility model relates to the field of LED lighting, in particular to an LED radiator and an LED bulb equipped with the radiator.

背景技术 Background technique

目前，LED光源以寿命长、无污染、光效高等特点正逐步替代白炽灯和荧光灯光源，故而出现了用LED作为光源的LED灯泡。但是LED光源的散热问题是LED灯泡需要解决的一个重要问题，散热效果的优劣直接关系到灯泡的发光效果及寿命。LED光源的热量集中在尺寸很少的电路板上，会使得灯泡内部温度越来越高，不但加速灯泡老化，缩短使用寿命。现有的LED灯泡几乎都是全密封结构的，散热效果较差，针对LED灯泡的散热难题，市场上LED灯泡的散热措施五花八门，大部分只通过在外部加装一些散热构件来促进散热，这样的设计比较繁琐复杂，而且散热效果不理想，影响了LED灯泡的美观及使用寿命。 At present, LED light sources are gradually replacing incandescent and fluorescent light sources with the characteristics of long life, no pollution, and high luminous efficiency. Therefore, LED bulbs using LEDs as light sources have appeared. However, the heat dissipation problem of LED light sources is an important problem that LED bulbs need to solve. The quality of the heat dissipation effect is directly related to the luminous effect and life of the bulb. The heat of the LED light source is concentrated on the circuit board with a small size, which will make the internal temperature of the bulb higher and higher, which will not only accelerate the aging of the bulb, but also shorten the service life. Existing LED light bulbs are almost all hermetically sealed, and have poor heat dissipation effects. To solve the heat dissipation problem of LED light bulbs, there are various heat dissipation measures for LED light bulbs on the market. Most of them only add some heat dissipation components to the outside to promote heat dissipation. The design of LED bulbs is cumbersome and complicated, and the heat dissipation effect is not ideal, which affects the appearance and service life of LED bulbs.

因此，如何实现一种结构简单且高效散热的LED散热器及LED灯泡，是业内亟待解决的技术问题。 Therefore, how to realize an LED heat sink and LED light bulb with simple structure and efficient heat dissipation is a technical problem to be solved urgently in the industry.

具体实施方式 Detailed ways

应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。 It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

参照图1至图4，提出本实用新型的一种LED散热器的一实施例，散热器的主体为空心的散热柱体100，散热柱体100上端面为用于设置LED光源组件的封口端面101，这样LED光源组件发出的热量可以及时地从封口端面101传递到整个散热器。 Referring to Fig. 1 to Fig. 4, an embodiment of a LED heat sink of the present invention is proposed, the main body of the heat sink is a hollow heat dissipation cylinder 100, and the upper end surface of the heat dissipation cylinder 100 is a sealing end surface for setting the LED light source assembly 101, so that the heat emitted by the LED light source assembly can be transferred from the sealing end surface 101 to the entire heat sink in time.

另外，散热柱体100外侧壁朝外延伸出散热架，散热架包括若干罩设在散热柱体100外侧的垂直散热片201、与垂直散热片201一一对应并连接垂直散热片201与散热柱体100外侧壁的散热肋条202，若干垂直散热片201之间、垂直散热片201与散热柱体100之间均为可让空气流动的镂空空间，垂直散热片201、散热肋条202的数量设置为6至12。这样简单的结构，可利用内外部空气的自发流动就可以及时迅速地将LED光源组件产生的热量传递到外部空气中，大大提高了散热器的散热效果，避免了热量囤积在LED光源组件处，使得LED光源组件的LED光源高效发光，延长使用寿命。 In addition, the outer wall of the heat dissipation cylinder 100 extends outwards from the heat dissipation frame, and the heat dissipation frame includes a number of vertical heat dissipation fins 201 arranged on the outside of the heat dissipation cylinder 100, corresponding to the vertical heat dissipation fins 201 and connecting the vertical heat dissipation fins 201 and the heat dissipation column.

封口端面101上设有可通线并可进行空气流动的通孔102。透光罩内部与外部空气可进行空气流动，而通孔102连通透光罩内部及散热器内部，这样，通孔102可有效地将散热器内的热量通过空气流动散发到外部空气中。 The sealing end surface 101 is provided with a through hole 102 through which wires and air can flow. The inside of the light transmission cover and the outside air can carry out air flow, and the through hole 102 communicates with the inside of the light transmission cover and the inside of the radiator, so that the through hole 102 can effectively dissipate the heat in the radiator to the outside air through the air flow.

另外，本实用新型的LED散热器采用导热性强的材料制成，如铝、铁、铜或其他具有导热性的材料，而且是一体成型结构，LED光源上产生的热量传递到封口端面101上后，封口端面101可以快速地将热量转移到散热器的各个部分，并通过上述镂空空间使热量迅速传递到外部空气中。本实用新型的LED散热器设计新颖，结构简单，散热效果好，适宜广泛的推广应用。 In addition, the LED radiator of the present invention is made of materials with strong thermal conductivity, such as aluminum, iron, copper or other materials with thermal conductivity, and is an integrally formed structure, so that the heat generated by the LED light source is transferred to the sealing end surface 101 Finally, the sealing end surface 101 can quickly transfer heat to various parts of the heat sink, and quickly transfer the heat to the outside air through the above-mentioned hollow space. The LED heat sink of the utility model is novel in design, simple in structure and good in heat dissipation effect, and is suitable for wide popularization and application.
