本发明涉及一种 LED射灯， 特别是一种大功率 LED射灯。 背景技术 The invention relates to an LED spotlight, in particular to a high power LED spotlight. Background technique
日前， LED (发光二极管） 技术发展迅速， LED 光源在照明市场上 占据的比例越来越大。 801m I W 的大功率 LED 产品的出现， 使 LED 取 代普通照明灯泡的趋势越来越明显。 Recently, LED (Light Emitting Diode) technology has developed rapidly, and the proportion of LED light sources in the lighting market is increasing. With the advent of 801m I W high-power LED products, the trend of replacing LEDs with ordinary lighting bulbs is becoming more and more obvious.
相比于传统的光源， 大功率 LED用作照明灯泡， 尤其是用于射灯， 其 优点在于低压供电， 单芯片 LED工作电压一般在 3-4 伏， 远低于普通灯 泡光源的工作电压， 安全可靠； 结构简单， 属于固体光源， 对比起钨丝光 源， 具有耐冲击， 耐震动， 不易破碎等优点； LED 是冷光源， 可控性好， 响应时间快， 可反复频繁亮灭， 传统的钨丝光源若频繁亮灭必会由于快速 的热胀冷縮而使得寿命骤减； LED光源的使用寿命长， 达 5 万小时以上， 是白炽灯等传统光源的 4到 5倍，免于频繁的维修和更换； LED高效节能， 其发光光谱几乎都集中在可见光频段， 照明效果比传统光源节能 50 %以 上； LED光源绿色环保， 生产过程中无有害元素和重金属、 无污染。 Compared with traditional light sources, high-power LEDs are used as lighting bulbs, especially for spotlights. The advantage is that low-voltage power supply, single-chip LEDs generally operate at 3-4 volts, much lower than the operating voltage of ordinary bulb sources. Safe and reliable; simple structure, belonging to solid light source, compared with tungsten light source, has the advantages of impact resistance, vibration resistance, and not easy to break; LED is a cold light source, good controllability, fast response time, repeated frequent and frequent, traditional If the tungsten light source is frequently turned on and off, the life will be suddenly reduced due to rapid thermal expansion and contraction. The long life of the LED light source is more than 50,000 hours, which is 4 to 5 times that of traditional light sources such as incandescent lamps. The maintenance and replacement of LED; LED energy-efficient, its luminescence spectrum is almost concentrated in the visible light band, the lighting effect is more than 50% energy saving than the traditional light source; LED light source is green and environmentally friendly, no harmful elements and heavy metals in the production process, no pollution.
日前， 市面上 LED射灯其结构一般包括三部分： 前端为一透镜， 用于 聚焦 LED出射的光线， 中间部分为一金属灯体， 用于安装 LED芯片和散热， 尾端为一中空的绝缘体， 用以容纳驱动电路， 其后端设有与灯座配合的插 杆。 Recently, the structure of LED spotlights on the market generally consists of three parts: the front end is a lens for focusing the light emitted by the LED, the middle part is a metal lamp body for mounting the LED chip and heat dissipation, and the tail end is a hollow insulator. , to accommodate the drive circuit, the rear end of which has a plunger that cooperates with the lamp holder.
其中， 金属灯体结构中， LED封装芯片先安装于一金属基的线路板上， 此线路板底部涂上导热胶后， 再用螺丝紧固到灯体上。 线路板用于安装封 装芯片和引线， 同时起导热作用。 Wherein, in the metal lamp body structure, the LED package chip is first mounted on a metal-based circuit board, and the bottom of the circuit board is coated with thermal conductive glue, and then screwed to the lamp body. The board is used to mount the package chip and leads while conducting thermal conduction.
目前的 LED射灯一般采用大功率的 LED芯片， 其工作时发热量较大， 如不能及时将芯片工作时产生的热量散出， 则会影响射灯的正常工作和使 用寿命。 而上述结构的 LED射灯， 其 LED芯片产生的热量需通过线路板的 中间传递才能传输到作为散热器的金属灯体上。 通常在金属灯体的外表面 上开设有若干翼展型散热部， 以提高散热效果。
由于人们在安装 LED射灯时， 需要用手指捏住金属灯体进行旋转， 虽 然 LED射灯的电压很低， 属于安全范围， 但总归的金属灯体， 人们有一种 怕触电的感觉， 使人们在安装 LED射灯时存在心理负担。 发明内容 The current LED spotlights generally use high-power LED chips, which generate a large amount of heat during operation. If the heat generated by the chip is not released in time, the normal operation and service life of the spotlights will be affected. In the LED spotlight of the above structure, the heat generated by the LED chip needs to be transmitted through the middle of the circuit board to be transmitted to the metal lamp body as a heat sink. Generally, a plurality of span-type heat radiating portions are formed on the outer surface of the metal lamp body to improve the heat dissipation effect. Since people need to pinch the metal lamp body to rotate when installing the LED spotlight, although the voltage of the LED spotlight is very low, it belongs to the safe range, but the metal lamp body always has a feeling of being afraid of electric shock, which makes people There is a psychological burden when installing LED spotlights.
