Light-emitting diode (LED) tunnel lamp

Abstract

The invention relates to a light-emitting diode (LED) tunnel lamp, which comprises LED lamp caps, a front cover, a radiator and a tail cover. The LED lamp caps respectively consist of a substrate, a plurality of single chip LEDs, a lamp cap seat and a lens. The radiator consists of two eudipleural lambdoidal hollow cylindrical objects and fins respectively arranged on convex surfaces of the hollow cylindrical objects; the LED lamp caps are respectively arranged on lambdoidal angular surfaces of nearly symmetric axis on concave surfaces of the hollow cylindrical objects of the radiator; and the front cover and the tail cover are fixedly arranged on the radiator through screws. The LED tunnel lamp has the following advantages: 1, under the action of an open illumination chamber, light distribution of the LED lamp caps is even, and the light intensity is enhanced; 2, natural ventilation channels are additionally arranged on the radiator, and therefore, power consumption-free heat dissipation is realized, the junction temperature of the LED tunnel lamp is reduced, and the light decay speed of the LED tunnel lamp is reduced; and 3, a shell-type structure of the front cover and a shell-type structure of the tail cover are communicated with the outside through an upper space and a lower space, and therefore, the LED tunnel lamp is ventilated without accumulated water, the working environment of the LED tunnel lamp is improved, and the service life of the LED tunnel lamp is greatly prolonged.

Description

Technical field: [0001] The invention relates to an illuminating LED lamp, in particular to an LED tunnel lamp. Background technique: [0002] As the state invests more in infrastructure, traffic becomes smoother. Not only surface roads, but also caves, underground, and submarine tunnels are getting longer and longer, accompanied by lighting problems. Traditional tunnel lighting mainly uses high-power tungsten lamps, iodine-tungsten lamps, and mercury lamps. These light sources use high voltage and high current, are large in size, heavy in weight, high in energy consumption, cause serious environmental pollution, short life, and unsatisfactory lighting effects. In recent years, the development of LED lights has been extremely rapid.

Problems solved by technology

Traditional tunnel lighting mainly uses high-power tungsten lamps, iodine-tungsten lamps, and mercury lamps. These light sources use high voltage and high current, are large in size, heavy in weight, high in energy consumption, cause serious environmental pollution, short life, and unsatisfactory lighting effects.

In recent years, the development of LED lights has been extremely rapid. At present, the shortcomings of LED lighting in tunnels are: first, the light distribution is uneven, the middle is bright and the periphery is dark, and the lighting effect is not good; second, in order to achieve sufficient brightness, multiple lights must be used A single LED, due to the difficulty of heat dissipation, leads to many problems of high heat; the third is that the tunnel is relatively humid, requiring moisture-proof and waterproof, which puts forward higher requirements for LED lights.
