技术领域technical field
本发明涉及照明领域，具体涉及一种散热性好、可快速更换光源的LED灯。The invention relates to the field of lighting, in particular to an LED lamp with good heat dissipation and fast light source replacement.
背景技术Background technique
LED(Light Emitting Diode)，发光二极管，是一种能够将电能转化为可见光的固态的半导体器件，它可以直接把电转化为光。LED灯的出现，相对于普通灯(白炽灯等)具有节能、寿命长、适用性好、回应时间短、环保等优点，LED灯按不同的结构又可分为：球泡灯、射灯、日关灯、灯丝灯、吊灯等。LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. Compared with ordinary lamps (incandescent lamps, etc.), the emergence of LED lights has the advantages of energy saving, long life, good applicability, short response time, and environmental protection. LED lights can be divided into different structures according to different structures: bulb lamps, spotlights, Sun lights, filament lamps, chandeliers, etc.
虽说LED的寿命长，但也不排除在封装或使用过程中对LED光源的损坏导致LED光源提前报废，若将整灯全部更换，就浪费了其他部件的资源。中国实用新型专利公告号CN203615120U揭示了一种LED灯具，包括：LED灯珠组件(即LED光源)以及散热器，所述散热器开设开孔，所述开孔尺寸小于所述LED灯珠组件的尺寸；散热器受热时，开孔增大且与LED灯珠组件相匹配；散热器冷却时，所述开孔与所述LED灯珠组件锁固。该专利文件利用了材料的热胀冷缩原理，对散热器的开孔进行加热，然后再冷却，达到LED灯珠组件与散热器之间的固定，若LED灯珠组件损坏，需再次对散热器的开孔进行加热，取出LED灯珠组件进行更换。但该专利通过开孔的侧壁与LED灯珠组件的侧壁进行卡固接触，其接触面积有限，由于尺寸的偏差，较难完全接触，导致LED灯珠组件的热量散热不足，LED灯珠组件累积的热量直接影响LED灯珠组件的光效及寿命；再者，在安装或更换组件时，需加热散热器的开孔，其开孔位置附近设置的导线等器件也会因加热受到的热量容易损坏，且此操作繁琐，变量较大，效率不高，风险较大。Although LEDs have a long service life, it is not ruled out that damage to the LED light source during packaging or use will cause the LED light source to be scrapped ahead of time. If the entire lamp is replaced, the resources of other components will be wasted. Chinese Utility Model Patent Announcement No. CN203615120U discloses an LED lamp, comprising: an LED bead assembly (i.e., an LED light source) and a radiator, and the radiator is provided with an opening, and the size of the opening is smaller than that of the LED bead assembly. Dimensions; when the heat sink is heated, the opening increases and matches the LED light bead assembly; when the heat sink cools down, the opening is locked with the LED light bead assembly. This patent document uses the principle of thermal expansion and contraction of the material to heat the opening of the radiator, and then cool it to achieve the fixation between the LED lamp bead assembly and the radiator. If the LED lamp bead assembly is damaged, it is necessary to heat the radiator again Heat the opening of the device, and take out the LED lamp bead assembly for replacement. However, in this patent, the side wall of the opening and the side wall of the LED lamp bead assembly are clamped and contacted. The contact area is limited. The heat accumulated by the components directly affects the light efficiency and life of the LED lamp bead components; moreover, when installing or replacing the components, it is necessary to heat the opening of the radiator, and the wires and other devices installed near the opening will also be affected by the heat. Heat is easy to damage, and this operation is cumbersome, with large variables, low efficiency and high risk.
