Description

LED high power street light structure

The present invention relates to a street lamp, and more particularly to an LED high-power street lamp structure using LED as an illumination material and improving the brightness of LED light through a reflector. Background technique

Since the invention of electric lights, humans have been more than a hundred years old, but electric lights have long become an indispensable tool for daily life, making human activities at night active and meeting the needs of different people's night activities.

Night activities include indoor activities and outdoor activities. Indoor lighting is provided by the residents themselves, but outdoor lighting relies on public facilities, which are common street lighting devices. The use of street lamps as nighttime lighting tools is well known. Street lights are provided on all roads and streets in various towns to facilitate pedestrians and vehicles to walk and drive at night.

In order to provide sufficient brightness, most of the street lamps in the prior art use iodine tungsten lamps, high pressure sodium lamps, etc., but in the case of insufficient resources, some small cities or towns use incandescent lamps or fluorescent lamps. However, whether it is a iodine-tungsten lamp, a high-pressure sodium lamp, an incandescent lamp or a fluorescent lamp, its inherent disadvantage is that when it emits light, a part of the electric energy is converted into thermal energy, which is wasteful, and the photoelectric conversion efficiency is low, and the energy is consumed. Larger. Moreover, the failure rate of the traditional street lamp is high, and the maintenance cost is also high. In the case of limited maintenance personnel, many street lamps often break for a long time and the workers are not replaced, which causes inconvenience to the user.

The inventor of the present invention has invented the idea of improvement in view of the lack of conventional lamps, and the method uses LED as a light source. The development of LED has been quite a long time. Its advantages are low power consumption, low heat generation, ruggedness and long life.

However, with the progress of technology, the development of LEDs has gradually matured, and the products of high-brightness LEDs have sprung up like mushrooms. Therefore, LED as a lighting concept is feasible. Because it is durable and not easily damaged, it is also suitable for street lights, which are often used, but cannot be monitored at any time.

Of course, in order to achieve a clear means of high-brightness LED lighting, in addition to the LED itself, the problem of high-brightness LED heating, and the problem of inability to concentrate brightness, are areas for improvement. In terms of heat generation, it is necessary to cooperate with the modeling mode of the street lamp and use the existing heat dissipation structure to improve; and regarding the brightness problem, a major problem of the current LED lighting structure lies in the way of LED illumination, because the light source of the LED is a point. The light source emits, the light-emitting range is dispersed, the illumination range is hemispherical, and the illumination is not concentrated enough. The illumination is low.

It can be seen that there are still many shortcomings in the above existing methods, which is not a good designer and needs to be improved.
