High-power integrated LED road lamp

Abstract

The invention discloses a high-power integrated LED road lamp, which comprises a lamp post, a lamp holder arranged at the top end of the lamp post, a high-power integrated LED lamp arranged on the lamp holder, and a power supply for supplying power to the high-power integrated LED lamp, wherein the power supply comprises a constant voltage power supply and constant current drive circuits; the high-power integrated LED lamp is formed by integrating a plurality of groups of LED lamps; the number of the constant current drive circuit corresponds to the number of LED lamp integration groups, and each LED lamp integration group is connected with the corresponding constant current drive circuit; and the constant voltage power supply is arranged at the bottom of the lamp post and connected with a plurality of constant current drive circuits connected in series through power wires. Compared with the prior art, the high-power integrated LED road lamp has the advantages of convenient power supply maintenance, low maintenance cost and consistent luminescence of the LED integration groups.

Description

Technical field: [0001] The invention relates to a street lamp. Background technique: [0002] Existing high-power integrated LED street lights are generally composed of a light pole, a lamp holder set on the top of the light pole, a high-power integrated LED light set on the light base, and a power supply for the high-power integrated LED light. The power supply adopts All are constant voltage power supplies. Determined by the characteristics of the LED lamp, the constant voltage power supply is set in the lamp holder, so as to shorten the power line between the constant voltage power supply and the LED lamp as much as possible, and avoid the influence of the resistance of the power line itself on the stability of the power supply, so as to ensure Stability of power supply. This kind of high-power integrated LED street light has the following disadvantages: 1. Since the constant-voltage power supply is a relatively easily damaged part, once it is damaged, it is necessary ...

AI Technical Summary

Problems solved by technology

This kind of high-power integrated LED street light has the following disadvantages: 1. Since the constant-voltage power supply is a relatively easily damaged part, once it is damaged, it is necessary to use climbing tools to go up to the top of the light pole to repair and replace the constant-voltage power supply. First, it increases the difficulty and cost of maintenance, and also seriously affects the traffic of the road; 2, because the high-power integrated LED lamp is composed of many groups of LED integrated groups, and each group of LED integrated Composition, and the resistance of each LED lamp is different, the smaller the resistance, the larger the shunted current will be, and the brightness will be larger, so that the light emission of each LED integrated group is inconsistent.
