Embodiment Construction

[0012] according to Figure 1~3 The specific structure of the present invention will be described in detail. The LED street lamp includes a casing 3, an electronic ballast 1, an LED 5, a lampshade 6, an aluminum substrate 11 and other parts. Wherein, the housing 3 has a "U-shaped" structure, which is convenient for processing and reduces production costs. The opening of the "U-shaped" structure is limited by the lampshade limiting boss 9 with a lampshade 6 (the lampshade 6 can be fixed by bonding or screwing), and the lampshade 6 is just limited in the "U-shaped" structure, making the structure more compact and the shape more beautiful. The "U-shaped" structure and the lampshade 6 form an aluminum substrate fixing cavity 8, and the bottom of the aluminum substrate fixing cavity 8 is fixed with an aluminum substrate 11 by screws, and a number of LEDs are fixed on the aluminum substrate 11 through a heat-conducting adhesive 4, and a lamp bowl is arranged on the LED. The LED w...

Abstract

The invention relates to an LED street lamp and solves the problem that existing LED street lamps cannot be adjusted in light distribution angle. The LED street lamp comprises a shell, an electronic ballast, a plurality of LEDs, a lampshade and an aluminum substrate. The LED street lamp is characterized in that the shell is of a U-shaped structure, the lampshade is limited at an opening of the U-shaped structure, an aluminum substrate fixing cavity is formed between the U-shaped structure and the lampshade, an aluminum substrate is fixed to the bottom of the aluminum substrate fixing cavity, the LEDs are fixed on the aluminum substrate through thermally conductive adhesive, and a lamp bowl is arranged on each LED. A tubular street lamp fixing portion is arranged on the bottom surface of the U-shaped structure, the electronic ballast is fixed in the street lamp fixing portion, radiating fins perpendicular to the bottom surface of the U-shaped structure are arranged on two sides of the street lamp fixing portion, and the height of the radiating fins gradually decreases from the center of the bottom surface of the U-shaped structure to the edge in a stepped manner. The LED street lamp has the advantage of ingenious structural design, low manufacturing cost, good illumination effect, energy conservation and the like.

Description

technical field [0001] The invention relates to a lighting device, in particular to an LED street lamp. Background technique [0002] Existing outdoor street lamps often have problems such as short service life and high maintenance rate due to high internal temperature during long-term use. The light emitting direction of traditional LED street lights is fixed. For complex road surfaces or occasions with special requirements for the light emitting direction of LED street lights, the only way to adjust the LED street light is by adjusting the installation angle of the LED street light body, that is, adjusting the elevation angle of the installation. Light direction. To sum up, traditional LED street lights have the following defects: the light distribution angle is fixed, and the light spots projected on the road surface are difficult to meet the relevant light spot standards, and it is impossible to make different adjustments according to different road conditions. Conten...
