Description

巷道灯 Roadway lights

技术领域 FIELD

[0001] 本发明属于照明技术领域,更具体地说,是涉及一种巷道灯。 [0001] The present invention belongs to the technical field of lighting, and more particularly, to a roadway lights.

背景技术 Background technique

[0002] 随着氮化镓基第三代半导体的兴起,蓝色和白色发光二极管(LED)的研究成功,半导体照明带来了人类照明史上的又一次飞跃。 [0002] With the emergence of the third generation of gallium nitride-based semiconductor, a blue and white light emitting studies diode (LED) is successful, another leap brought semiconductor lighting history of mankind lighting. 与白炽灯和荧光灯相比,LED以其体积小、全固态、长寿命、环保、省电等一系列优点,成为新一代环保型照明光源的主要发展方向之一,也是21世纪最具发展前景的高技术领域之一。 Compared with incandescent and fluorescent lamps, LED with its small size, all solid, long life, environmental protection, energy saving and a series of advantages, one of the main direction of development of a new generation of environmentally friendly lighting sources, is the most promising in the 21st century one high-tech fields.

[0003] LED从诞生开始,一直伴随着热量管理的问题。 [0003] LED from birth, has been associated with thermal management issues. 它的发光机理是靠PN结中的电子在能带间的跃迀产生光能,当它在外加电场作用下,电子与空穴的辐射复合发生电致作用将一部分能量转化为光能,而无辐射复合产生的晶格震荡将其余的能量转化为热能。 Its light emission mechanism is by electrons generated in the PN junction in the energy band transitions between Gan, when it is under an applied electric field, Induced radiative recombination of electrons and holes occur portion of electrical energy into light, and nonradiative recombination generated the remainder of the lattice oscillation energy into thermal energy. 由于光谱中不含红外成分,产生的热量不能靠辐射散发,只能通过散热器传导到空气中。 Since the infrared component does not contain the spectrum, the radiation heat generated by distributing not only transferred to the air through the radiator.

[0004] 随着半导体产业的发展,作为21世纪最具发展前景的新型绿色光源,LED照明逐渐渗透到各行各业中,其中将其应用于巷道灯照明便是一个具体的例子。 [0004] With the development of the semiconductor industry, as the most promising new century green light 21, LED lighting gradually penetrate into all walks of life, which is applied to a roadway lighting specific example. 由于LED照明与传统照明技术有着较大的差别,目前LED光效不到30%,其余大多数能量转化为热能。 Since the conventional LED lighting and lighting technology has a large difference in current LED luminous efficiency less than 30%, most of the remaining energy is converted into heat. 灯具散热性能的好坏直接影响着其自身的使用寿命,而巷道灯一般使用的是大功率的LED,工作时发热量大,如果热能不能有效的排出,将会导致很严重的后果,如:高温会降低LED的光通量及其发光效率、引起光波红移、偏色,同时还会引起器件老化等不良现象,最重要的是会使LED寿命呈指数性缩减,资料显示,温度每升高10°C,寿命约减少一半。 Heat lamps performance directly affects the life of its own, but is generally used roadway lights the LED's high-power, heat, if not effectively discharge heat during operation, will result in very serious consequences, such as: high temperature reduces its luminous efficiency of the LED light emission, light waves causing red shift, color cast, while the aging device can also cause undesirable phenomena, most importantly, will reduce LED life exponentially, the data show, the temperature is increased 10 ° C, about half life is reduced. 因此,LED热管理十分重要。 Therefore, LED thermal management is very important. 尤其是对于大功率的巷道灯,对散热的要求也就更高。 Especially for the street lamp power, heat dissipation requirements will be higher. 当前,如需要驱动电源的LED光源等巷道灯的热量主要由灯座的下壳体与环境接触辐射散热(因为下壳体散热面积较大,其内部安装驱动电源),而上壳体只起到固定透明件和密封整个灯体的作用,LED灯板与下壳体固定接触散热,这种情况导致驱动电源热量与LED光源热量混合,驱动电源温度过高,影响其寿命,造成经常更换驱动电源,从而导致维护成本较高。 Currently, as the heat required to drive power LED street lamp light source from the environment in contact with the main housing and socket dissipation (heat dissipating area because of the larger lower housing, mounted therein a driving power source), but only from the upper case fixing the transparent member and the sealing action of the whole body of the lamp, LED lamp housing with the lower fixed contact plate heat, this heat causes the drive power hybrid heat the LED light source, power supply temperature is too high, affect their life, resulting in frequent replacement of the drive power supply, resulting in higher maintenance costs. 巷道灯外壳散热技术成为LED照明的关键技术之一。 Roadway lamp housing cooling technology plays a key role LED lighting.
