Improved high power LED road lamp

Abstract

The invention provides an improved high power LED streetlight with larger irradiated area and more hermetical sealing. The streetlight comprises a light source module, namely an upper casing body module, a light distribution module, namely a lower casing body module, and a casing body opening and closing module, wherein, the light source module is composed of a driving power source, a high power LED and an upper casing body, and the high power LED is installed on the upper casing body and connected with the driving power source; the light distribution module is composed of a reflection shade, a glass shade, a seal ring with a glass shade and a lower casing body, and the glass shade with the glass shade and the reflection shade are arranged on the lower casing body in sequence; the casing body opening and closing module is composed of a locking piece and a supporting piece, the locking piece connects two ends of the upper and the lower shell bodies as a whole and ensures the upper casing body rotate around a shaft, and the supporting module is connected with the other two ends of the upper and the lower shell bodies and ensures the upper and the lower shell bodies are closed or opened; and when the upper and the lower shell bodies are closed, the high power LED on the upper casing body is positioned at the middle part of the reflection shade which is on the lower casing body. The streetlight is mainly used for lighting a street.

Description

technical field [0001] The invention relates to a street lamp using LED as a light source, especially an improved high-power LED street lamp. Background technique [0002] The applicant submitted a patent application with application number 200810099758.X titled "High Power LED Packaging Structure" and application number 200810099757.5 titled "High Power LED Street Lamp" to the State Intellectual Property Office of China on June 4, 2008. The high-power LED packaging structure includes an insulator, an LED chip, a conductive support, a wire, and a heat dissipation block. The positive and negative conductive supports are partially wrapped by the insulator and integrally formed into a ring-shaped matrix, which is installed on the front of the heat dissipation block. The annular hole of the base body is installed on the front of the cooling block, and the positive and negative poles of several LED chips are connected with the positive and negative conductive supports through wir...

Problems solved by technology

However, this high-power LED street light uses a single high-power LED. Since the luminous angle of a single high-power LED is determined, the irradiation range has certain limitations, and its corresponding road irradiation area also has certain limitations.
