LED street lamp with LED lamp bead combination lens and power adjusting method thereof

Abstract

The invention discloses an LED street lamp with an LED lamp bead combination lens. The LED street lamp comprises a heat dissipation main body, a driving power source, a light source PCB and a connecting cable. The back surface of the heat dissipation main body is provided with a power source cavity back cover. A power source cavity matched with the driving power source is formed between the power source cavity back cover and the heat dissipation main body. A power source cavity waterproof rubber ring is arranged on the power source cavity. The front surface of the heat dissipation main body is provided with the combination optical lens which is formed by an optical PC material through injection molding. The combination optical lens is formed by combining a plurality of peanut-shaped lenses. Each peanut-shaped lens corresponds to one or more LED lamp beads. A light source cavity matched with the light source PCB is formed between the combination optical lens and the heat dissipation main body. A borrow hole used for arranging the connecting cable in a penetrating mode is formed between the power source cavity and the light source cavity. According to the LED street lamp with the LED lamp bead combination lens, the waterproof performance and the lighting effect are good; the energy saving effect is better; assembling and material preparing are easier and more convenient; the luminous efficiency is high; the customer selectivity is high; the life of the whole LED street lamp is long; and the lighting effect on the road surface is good.

Description

technical field [0001] The invention relates to a street lamp, in particular to an LED street lamp with an LED bead combination lens and a power adjustment method thereof. Background technique [0002] Existing LED street lamps use single 1W or integrated high-power 50W lamp beads plus lenses and glass. They use three-time light distribution, which has low light efficiency and high cost. In addition, the driving power and light source are processed separately, and the two are waterproof. The use of parts to connect requires additional parts to connect. The structure is complex, the energy-saving effect is low, and the assembly is difficult. [0003] And the lens is placed on a single light source with a peanut-shaped lens with light distribution, and N peanut-shaped lenses are combined into a combined lens, so that the power of the lamp corresponds to the number of peanut-shaped lenses one by one, and excessive adjustments cannot be made. If the power is achieved by adjusti...

Problems solved by technology

[0002] Existing LED street lamps use single 1W or integrated high-power 50W lamp beads plus lenses and glass. They use three-time light distribution, which has low light efficiency and high cost. In addition, the driving power and light source are processed separately, and the two are waterproof. Parts are used to connect, and other parts need to be added for connection. The structure is complex, the energy saving effect is low, and the assembly is difficult.

[0003] And the lens is placed on a single light source with a peanut-shaped lens with light distribution, and N peanut-shaped lenses are combined into a combined lens, so that the power of the lamp corresponds to the number of peanut-shaped lenses one by one, and excessive adjustments cannot be made. If the power is achieved by adjusting the current, it will seriously affect the life of the LED, and the light distribution is rectangular, and the road lighting effect is not good.
