Description

LED灯模块及装配有该模块的 LED路灯技术领域 LED light module and LED street lamp equipped with the same

本发明涉及一种灯模块和一种路灯，具体而言是涉及一种组装式的 LED 灯模块及装配有该模块的 LED路灯。背景技术 The invention relates to a lamp module and a street lamp, in particular to an assembled LED lamp module and an LED street lamp equipped with the module. Background technique

随着电子技术的科技进步， LED灯作为寿命长、体积小、耗电量小、亮度高的节能新光源而被人们广泛应用于各种照明设备上，其不足之处在于：一是现有的 LED灯的防水性差，致使有些灯体在路旁的灯杆上悬挂时，由于下雨进水而导致电源短路而损坏；二是由于单体 LED灯的发光量小，每盏 LED 灯大都由多个、甚至几十个单体 LED灯组合而成，每盏灯的生产制造都需要进行多个单体 LED灯的组装，当需要生产不同功率的 LED灯时，就需要按不同功率的需求组织生产，一旦客户对不同功率的 LED灯的需求数量有较大的变化时，需要重新设计制造模具，给生产带来极大的不便；三是维修性差，大部分的 LED灯中的部分单体 LED灯损坏，都会影响整个 LED灯的照明效果及使用性能，维修时需要对整个 LED灯进行更换，造成较大的人力、物力、财力的浪费；四是组装困难，生产效率低，不便于工厂化作业；四是散热性差，现有的 LED灯大都将多个单体 LED灯组装在一块 PCB板上， LED灯具的功率越大，灯具的散热面积就越大，另外根据热空气上升的道理，散热器边缘冷热空气容易流动，而散热器中心部分的冷空气不容易得到充分的补充，使冷热空气不能快速有效的对流，阻碍了中心部分热量的散发，造成了散热器中心温度高于边缘温度的不均衡现象，从而导致散热器中心的 LED结温升高，最终将导致 LED亮度急剧衰减或损坏，使 LED达不到本来所具有的使用寿命长的优良性能。发明内容 With the advancement of electronic technology, LED lamps are widely used in various lighting devices as a new energy-saving light source with long life, small size, low power consumption and high brightness. The disadvantages are as follows: The LED lamp is poor in water repellency, causing some of the lamp body to be suspended on the light pole of the roadside, causing damage to the power supply due to raining into the water; secondly, due to the small amount of light emitted by the single LED lamp, most of the LED lights are It is composed of multiple, even dozens of single LED lamps. Each lamp needs to be assembled with multiple single LED lamps. When it is necessary to produce LED lamps of different powers, it needs to be powered by different powers. Demand organization production, once the customer has a large change in the demand for LED lamps of different powers, it is necessary to redesign and manufacture the mold, which brings great inconvenience to the production; Third, poor maintainability, part of most LED lights The damage of the single LED lamp will affect the lighting effect and performance of the whole LED lamp. The entire LED lamp needs to be replaced during maintenance, resulting in greater manpower, material resources and financial resources. The fourth is the difficulty of assembly, low production efficiency, inconvenient for factory operation; Fourth, poor heat dissipation, most of the existing LED lights are assembled on a single PCB board, the greater the power of the LED lamps, The heat dissipation area of the luminaire is larger. In addition, according to the rising of the hot air, the hot and cold air on the edge of the radiator easily flows, and the cold air in the central part of the radiator is not easily supplemented, so that the hot and cold air cannot be quickly and effectively convected. It hinders the heat dissipation in the central part, causing the imbalance of the center temperature of the heat sink to be higher than the edge temperature, which leads to an increase in the junction temperature of the LED in the center of the heat sink, which will eventually cause the brightness of the LED to be sharply attenuated or damaged, so that the LED cannot reach the LED.
