Description

一种可直接代替荧光灯使用的 LED日光灯  LED fluorescent lamp that can directly replace fluorescent lamps
技术领域 Technical field
本实用新型涉及照明技术领域, 特别是涉及一种可直接代替荧光灯使 用的 LED日光灯。  The utility model relates to the technical field of illumination, in particular to an LED fluorescent lamp which can be directly used instead of a fluorescent lamp.
背景技术 Background technique
LED日光灯采用发光二极管作为光源, 光效更高、 更为节能、 使用寿命 更长, 而且更为环保。 LED日光灯节电高达 70%以上, 寿命为普通灯管的 10 倍以上, 已成为目前阶段代替荧光灯管的最理想产品。  LED fluorescent lamps use light-emitting diodes as a light source, which is more efficient, more energy efficient, longer lasting, and more environmentally friendly. LED fluorescent lamps can save up to 70% of electricity and have a lifespan of more than 10 times that of ordinary lamps. It has become the most ideal product to replace fluorescent tubes at this stage.
现有技术中, 如图 5所示, 几乎市场上所有 LED 日光灯都是采用内置 电源的 LED日光灯 22。 所谓内置电源就是指将电源放置于灯管里面。 这种 内置式的最大优点就是可以做成直接替换现有的荧光灯管, 而无需对原有 电路作任何改动。  In the prior art, as shown in Fig. 5, almost all LED fluorescent lamps on the market are LED fluorescent lamps 22 with built-in power. The so-called built-in power supply means that the power is placed inside the lamp. The biggest advantage of this built-in type is that it can be used to directly replace existing fluorescent tubes without any modification to the original circuit.
例如: 申请号为 201 120020876. 4的中国实用新型专利, 公开了 "一种 具有启辉器的 LED灯", 其技术方案包括 LED灯管和 LED启辉器, LED灯管 的每一端都设有两个端子, LED灯管一端的两个端子短接, 另一端的两个端 子为分立端子, 其中一个分立端子用于与一条电源进线相接, 另一个分立 端子通过 LED启辉器与短接的一个端子相接, 短接的另一个端子与另一条 电源进线相接。 LED灯管和 LED启辉器均安装在两端进线型灯座上, 该具有 启辉器的 LED灯能兼容传统的两端进线型灯座, 上述 LED灯采用了内置电 源的方式。  For example: Chinese utility model patent No. 201 120020876. 4 discloses "an LED lamp with a starter", and its technical solution includes an LED lamp tube and an LED starter, and each end of the LED tube is provided. There are two terminals, two terminals on one end of the LED tube are short-circuited, and the two terminals on the other end are discrete terminals, one of which is used to connect with one power supply line, and the other is connected to the LED starter. One shorted terminal is connected, and the other shorted terminal is connected to another power incoming line. Both the LED tube and the LED starter are mounted on the two-terminal type lamp holder. The LED lamp with the starter can be compatible with the traditional two-end type lamp holder. The above-mentioned LED lamp adopts the built-in power supply.
但这种电源内置式 LED日光灯存在以下缺陷: (1 ) 更换电源难度大。 LED的使用寿命远大于电源的使用寿命, 如果电源坏了, 直接更换整个 LED 日光灯将导致极大的浪费, 若只更换电源, 又必需依靠专业人员对电路进 行拆卸更换; (2 ) 影响 LED发光的质量。 发出的热量使得 LED日光灯在使 用过程中会产生眩光、 暗影和出光不够均匀柔和等; (3 ) 散热差。 由于电 源采用内置式, 电源的热量也就加入到灯管内, 使得 LED的散热又增加了 难度, 缩短了 LED的使用寿命; (4 ) 回收成本高, 内置电源式也增加了电 子垃圾的回收处理的成本, 因为必须把电源部分拆出来再分别处理; (5 ) 很难达到安规的标准。 由于电源内置, 对达到安规标准造成很大影响。 However, this type of built-in LED fluorescent lamp has the following defects: (1) It is difficult to replace the power supply. The service life of the LED is much longer than the service life of the power supply. If the power supply is broken, directly replacing the entire LED fluorescent lamp will result in great waste. If only the power supply is replaced, it is necessary to rely on the professional to disassemble and replace the circuit; (2) affecting the LED illumination the quality of. The heat emitted makes the LED fluorescent lamp In the process of use, glare, shadow and light are not evenly soft and so on; (3) poor heat dissipation. Since the power supply is built-in, the heat of the power supply is added to the lamp, which makes the heat dissipation of the LED more difficult and shortens the service life of the LED. (4) The recycling cost is high, and the built-in power supply also increases the recycling of electronic waste. The cost of processing, because the power supply must be removed and processed separately; (5) It is difficult to meet the safety standards. Due to the built-in power supply, it has a great impact on meeting safety standards.
由于内置电源的 LED 日光灯存在上述缺陷, 随之人们又发明了一种外 置电源的 LED日光灯。  Due to the above drawbacks of the LED fluorescent lamp with built-in power supply, an LED fluorescent lamp with an external power supply was invented.
例如: 申请号为 200920134372. 8的中国实用新型专利公开了 "一种外 置的 LED电源的 LED日光灯" , 其结构包括 LED日光灯体, 该 LED日光灯 体上连接有一外置的 LED电源, 所述外置的 LED电源包括 PCB电路板、 输 入和输出端子、 电源盒, PCB 电路板内置于电源盒中, 输入端子通过 PCB 电路板、 输出端子与 LED 日光灯体连接。 该外置的 LED电源的 LED日光灯 虽解决了内置电源的 LED 日光灯所存在的一些缺陷, 但由于其电源安装需 要改变原有的线路, 才能将其固定在传统日光灯的灯板上, 需要重新改变 原有的灯板电路结构。  For example, the Chinese utility model patent with the application number 200920134372. 8 discloses "an LED fluorescent lamp with an external LED power supply", the structure thereof comprises an LED fluorescent lamp body, and an external LED power source is connected to the LED fluorescent lamp body, The external LED power supply includes a PCB circuit board, input and output terminals, and a power supply box. The PCB circuit board is built in the power supply box, and the input terminal is connected to the LED fluorescent body through the PCB circuit board and the output terminal. The LED fluorescent lamp of the external LED power supply solves some defects of the built-in power LED fluorescent lamp, but since the power supply installation needs to change the original circuit, it can be fixed on the lamp board of the traditional fluorescent lamp, and needs to be changed again. The original lamp board circuit structure.
