Problems solved by technology

However, there are ventilation holes or air convection slots on the back of the radiator, which need to be machined, which greatly increases the difficulty of production operations. The back of the radiator is a whole plane or a hollowed out plane, which will easily cause the accumulation of foreign objects such as ice and snow, and increase the size of the lamp. Weight poses a safety hazard for lamps

Embodiment 1

[0027] like Figure 4As shown, in this example, the heat sink 5 of the LED street light includes the back of the heat sink and a plurality of heat dissipation fins 51 , and the number of the heat dissipation fins 51 is related to the heat dissipation capability. The back of the radiator is an integral arc surface 52 to prevent a large amount of dust or other solid objects from accumulating on the radiating fins 51 to affect the heat dissipation capacity and the weight of the lamp, and is easy to process and reduce manufacturing difficulty. The fixed light source surface 55 is a whole plane on which the LED light source module is fixed. The heat dissipation fins 51 and the fixed light source surface 55 are integrally designed to further reduce the processing difficulty. A heat dissipation hole is provided between the heat dissipation fin 51 and the back of the heat sink to enhance the heat dissipation capability. Specifically, the middle fin, that is, the most central heat diss...

Embodiment 2

[0029] like Figure 5 As shown, in this example, the heat sink 5 of the LED street light includes the back of the heat sink and a plurality of heat dissipation fins 51 . The more heat dissipation fins 51 are, the better the heat dissipation performance. The fixed light source surface 55 is a whole plane on which the LED light source module is fixed. The heat dissipation fins 51 and the fixed light source surface 55 are integrally designed to reduce processing difficulty. Taking the middle fin of the radiator 5, that is, the most central radiating fin 51 along the length direction, as the axis of symmetry, the back of the radiator includes a first arc surface 53 and a second arc surface 54 that are symmetrical to each other to save costs; Asymmetrical two arc surfaces can also achieve the same effect, but the cost is slightly higher. The middle fins are also fixed fins, which can support and fix the back of the radiator. The left and right sides of the radiator and the two si...

Abstract

The invention relates to an LED (light emitting diode) streetlamp, which aims at solving the technical problem for providing an LED streetlamp capable of effectively balancing the left side and the right side of the lamp for a long time. The technical scheme is as follows: the LED streetlamp comprises a cavity with a lamp body, wherein the cavity comprises a front end cavity, a heat radiating cavity and a control cavity, the front end cavity is arranged on the front end of the heat radiating cavity, a heat radiator is arranged in the heat radiating cavity, the heat radiating cavity is also arranged on the front end of the control cavity, the rear end of the control cavity is provided with a connecting column which is connected with a lamp pole, and the LED streetlamp also comprises a control cavity upper cover and a control cavity lower cover, which are respectively arranged on the upper part and the lower part of the front end cavity as well as a front end cavity upper cover and a front end cavity lower cover, which are respectively arranged on the upper part and the lower part of the front end cavity, and the control cavity lower cover is provided with a horizontal pipe storage groove. The horizontal pipe storage groove is arranged in the control cavity lower cover, so that the lamp can be effectively adjusted to be balanced in the left-right direction, the uniformity in illumination can be realized, and the problem of the inconsistency of the brightness on the road can be avoided; moreover, a horizontal pipe is arranged in the horizontal pipe storage groove to be adjusted when the adjustment is needed, so that the LED streetlamp can be used for a long time; and the LED streetlamp is applicable to the traditional streetlamp.

Description

technical field [0001] The invention relates to an LED street lamp. Background technique [0002] With the development of semiconductor chip and packaging technology, the luminous efficiency of LED has been rapidly improved. LED has many advantages such as small size, long life, high electro-optical efficiency, environmental protection and energy saving. It is widely used in LED street lighting and has become a research hotspot, and will gradually replace traditional lighting. In 2009, the Ministry of Science and Technology of the People's Republic of China promoted the "Ten Cities, Ten Thousand Lights" plan, which led to the upsurge of LED outdoor lighting product design and research all over the country. [0003] The existing street lamp has an aluminum profile support arm on each side along the length direction of the lamp, and the head end and the tail end shell are fixed along the length section direction. Generally speaking, a device for adjusting the elevation angle ...
