Description

A kind of LED street light

Technical field:

The invention relates to the technical field of lighting products, in particular to an LED street lamp. the

Background technique:

Energy, especially electric energy, is becoming increasingly tense. In order to achieve the purpose of environmental protection and energy saving, LED has the following advantages: 

1. The light emission of LED is unidirectional, without light diffusion, ensuring the light efficiency;

2. The light source efficiency of LED has reached 90-110lm/W at present, and there is still a lot of room for development, with a theoretical value of 250lm/W. the

3. The light color rendering of LED lights is much higher than that of traditional lighting;

4. The light decay of LED lights is small, and the light decay is less than 3% in one year, and it still meets the road use illumination requirements after 10 years of use;

5. LED is a low-voltage device. The voltage to drive a single LED is a safe voltage. The power of a single LED in a series of products is mostly 1 watt, so it is a safer power supply than using a high-voltage power supply. It is especially suitable for public places (for example: street lamps) lighting, etc.);

6. Each unit LED chip has only a small volume, so it can be prepared into devices of various shapes, and is suitable for variable environments. the

9. Long service life: it can be used for more than 50,000 hours. the

So various LED street lights are more and more applied to human life. The light emitted by the light source in the LED street lamps currently on the market is emitted through the light-transmitting cover to provide lighting for people to travel, but there are still deficiencies in this LED street lamp: 1. The support plate in the LED street lamp is not integrally formed, which is inconvenient Mass production; 2. No good sealing structure is adopted, which causes rainwater to enter the circuit box or enter the circuit board and LED chip in a rainy environment, thereby making it unable to work normally. 3. The reflector in the LED street lamp is a circular bell mouth with a parabolic surface, and some reflectors use a rectangular or quasi-rectangular bell mouth, and the reflective surface is usually a curved surface. This type of reflector is mainly to reflect light to a focal point to form concentrated light; these reflectors have certain shortcomings, because the distance between the lamps of the street lamp and the ground is relatively high, and the light from the light source can directly shine on the bottom itself. very few. If the above-mentioned lighting method of gathering light is still used, the main bright area of the light-irradiated surface on the bottom surface will be concentrated in a small "focus" range, while the brightness of other areas will be obviously darker than the central "focus" Area. This causes uneven distribution of reflected light, and the effective area irradiated by street lamps is too small, so that there are blind spots between street lamps. the
