Problems solved by technology

In order to meet different road illumination requirements, the development cycle and the number of mold development are greatly increased, and the development cost and production cost are increased; at the same time, when a LED street lamp module unit fails, the damaged module unit cannot be repaired and replaced. The entire LED street lamp must be repaired and replaced, which greatly increases the cost of repair and replacement

Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing:

[0021] Such as figure 1 , figure 2 with image 3 The new bridge-type LED street lamp shown includes an LED lamp assembly, a heat conduction substrate 8 arranged directly below the LED lamp assembly for heat conduction, and a heat dissipation body connected to the heat conduction substrate 8. The LED lamp assembly is mainly composed of a lamp head assembly 5, The LED street lamp array and the lamp tail assembly 4 are composed; at least two LED street lamp units 7 form the LED street lamp unit group, and the LED street lamp array is composed of at least one group of the above-mentioned LED street lamp unit groups, and pass between each two groups of the above-mentioned LED street lamp unit groups. The connector 6 is fixedly connected; the lamp head assembly 5 and the lamp tail assembly 4 are respectively fixedly connected with the first and last two groups of LED street la...

Abstract

The invention relates to a street lamp, in particular to a novel bridge type light emitting diode (LED) street lamp. In the invention, a unitized lamp body component structure is adopted; The purpose of serialization is realized by combining different quantity of units, thus the development cycle and the mold development quantity are greatly reduced, and the development cost and the production cost are lowered on the premise of satisfying different road illuminating value requirements. Since the lamp body component consists of a plurality of standard LED street lamp units, when one LED street lamp unit fails, the normal operations of other LED street lamp units are not influenced, and maintenance and replacement are carried out on the abnormal unit, thereby greatly reducing the maintenance cost and the replacement cost; and simultaneously, in the invention, a mode that heat pipe heat dissipation and metal material heat dissipation are combined is adopted, thus greatly improving the heat conduction and heat dispersion performances and being especially suitable for heat dissipation of large-power LED light sources.

Description

technical field [0001] The invention relates to a street lamp, in particular to a novel bridge-type LED street lamp. Background technique [0002] At present, the illuminants used in street lamps can be mainly divided into three types: halogen bulbs, xenon bulbs and LEDs. In particular, the LED has reached the technical level of high brightness in terms of current technology. However, when the above-mentioned LEDs are to be applied to street lamps, it is still necessary to use multiple LEDs to provide sufficient brightness, which complies with the relevant laws and regulations of street lamps. However, the luminous efficiency of the LED itself only accounts for about 20% of the input energy, and about 80% of the input energy is dissipated as heat, so higher heat energy will be generated in power consumption. When multiple LEDs are applied to car lights, high heat energy will be generated, and if the heat energy generated by the LEDs cannot be eliminated by other means, the...
