(2) Background technology

Street lamps are an indispensable basic public facility in modern society and are widely used in road lighting at all levels; with the continuous advancement of LED technology, LED street lamps have also been widely used. However, the existing conventional LED street lights have the following deficiencies:

(1) Conventional LED street light sources usually use a single LED series-parallel connection on the PCB substrate. Due to the small luminous power of a single LED, dozens or even hundreds of LEDs are often required, resulting in large size and complex structure of LED street lights. ;

(2) And due to the excessive number of single LEDs, the light emission is too scattered, resulting in a considerable part of the light not being fully utilized during use, resulting in a waste of electric energy;

(3) At the same time, since a single LED is arranged on the plane of the PCB substrate, the light-emitting angle of the LED can only be limited to a plane of 180°, and the irradiation surface is narrow;

(4) Conventional LED street lamps usually use their own shells for heat dissipation, and the heat dissipation effect is poor.

(3) Contents of the invention

The purpose of the utility model is to overcome the above disadvantages and provide an LED road lighting lamp with simple structure, energy saving, wide irradiation area and remarkable heat dissipation.

The purpose of this utility model is achieved as follows: an LED road lighting lamp, which includes an outer shell, a flip cover, a heat dissipation component, an LED light source, a supporting component, a power supply, a cover plate, a buckle and a connecting and rotating structure;

The outer casing includes a main casing, a right frame and a left frame. Two bottom rail grooves are arranged parallel to the bottom of the main casing, and two inner rail grooves are arranged parallel and symmetrically on both sides of the inner wall of the main casing. There is an opening in the middle of the left frame, and the left frame and the right frame are arranged at both ends of the main casing;

The heat dissipation assembly includes a radiator and a bracket, the bracket is fixed at one end of the track groove at the bottom of the main housing, and the radiator is fixed on the bracket;

The LED light source includes an LED base, an LED integrated block and an LED pressing block. The top of the LED base is symmetrically provided with two slopes. The LED base is fixedly arranged on the upper surface of the radiator, and the LED integrated block is arranged on the LED base. On the two slopes, the LED pressing block is arranged on the LED integrated block;

The support assembly includes a support frame and a bead, the support frame is fixed to the other end of the bottom track groove of the main housing, the two sides of the support frame are fixed to the inner track groove, and the bead is fixed to the bottom of the support frame The power supply is fixed on both sides of the support frame, and the power supply is connected to the LED integrated block through wires; the cover plate is fixedly connected to the top edge of the support frame;

The flip cover includes a flip cover frame, a transparent cover and a reflector. The transparent cover is arranged on the top of the flip cover frame. The reflector is a bowl-shaped structure and is arranged at the bottom of the flip cover frame. rectangular opening;

One side of the flip cover is connected to the main housing through a buckle; the other side of the flip cover is connected to the main housing through a connecting rotating structure; both slopes of the LED base form an inclination angle of 15° with the bottom surface; all parts of the The connections are all coated with waterproof glue.

The beneficial effect of the utility model is that: since the LED integrated block is used as the light source, a large number of single LEDs and a huge PCB substrate are no longer needed, so that the structure of the LED street lamp is simplified; at the same time, after the LED integrated block is used, the area of the light source is large Shrinking makes the light more concentrated and makes full use of light energy, thus saving a lot of electric energy; because the inclined surface of the LED integrated block is placed at an angle of 15° to the bottom surface, the luminous angle of the LED street light reaches 210°, which increases the illumination of the LED street light Range: A special heat sink is set in the LED street lamp housing to dissipate heat from the LED integrated block. Compared with conventional LED street lamps, the heat dissipation area is increased, making the heat dissipation effect more obvious.
