Prolate-type LED street lamp

Abstract

The invention relates to a prolate-type LED street lamp and a design method thereof. The method comprises the following steps: a. calculating the street illumination width and length; b. designing total luminous flux of the street lamp; c. calculating the number of LEDs used by the LED street lamp; d. designing the number of transverse LEDs of the prolate-type LED street lamp; e. grouping the LEDs; f. calculating the heat Q1 given off by the LEDs within the unit volume; g. setting ambient temperature, heat conduction quantity of the plane part of a shell of the street lamp, heat transmission and dissipation of a vane as well as air heat dissipation; and h. designing and calculating the sizes of the shell of the street lamp, the heat dissipation plane and the vane according to the set parameters. The street lamp comprises a street lamp heat dissipation plane part, the street lamp heat dissipation vane and an LED illuminating group; wherein the street lamp heat dissipation plane part has prolate-type design, and 1-6 transverse LED(s) is / are arranged on the prolate-type LED street lamp. By prolonging the design structure of the LED street lamp, the heat dissipation cross sectional area can be reduced, a heat dissipation system of the LED street lamp is improved, the heat emission efficiency is increased, and the luminous stability of the LEDs can be ensured.

Description

【Technical field】 [0001] The technical solution of the present invention relates to the field of LED street lamp manufacturing, in particular to a method for manufacturing an LED street lamp with increased power and a structure of the LED street lamp. 【Background technique】 [0002] LED street lamps have been installed on the road in large quantities, and the effect of use is good. It has the advantage of saving electricity by 40% to 60%. At present, integral and approximately rectangular LED street lamp products are generally used. With the increase of power, its length and width are increasing, which brings certain difficulties to the overall heat dissipation of street lamps, because when the size increases, the central part The heat dissipation effect will become weaker and weaker, seriously affecting the stability of light emission and service life. 【Content of invention】 [0003] In order to solve the problems of heat dissipation and stable light emission of LED stre...
