Combined type LED (light emitting diode) road lighting lamp

Abstract

The invention provides a combined type LED (light emitting diode) road lighting lamp which is composed of light-emitting modules and a power supply module, wherein the light-emitting module can be arranged on a lamp post or an extended structure of the lamp post in group and can be independently assembled or disassembled or replaced, and the power supply module is matched with the light-emitting modules; each light-emitting module is composed of a connector, a carrying box and a light source component which is arranged in the carrying box; and the power supply module is composed of a connector, a carrying box and a light source component which is arranged on the carrying box. By adopting the lamp provided by the invention, only several types of light-emitting modules can form street lamps for all roads in the same region, the lighting capacity of the street lamps can be changed only by increasing or decreasing the light-emitting modules, the most suitable radiator can be selected according to the climatic environment, the modeling of the street lamps can be changed by virtue of choosing the radiators with different appearances, the lighting effect can be adjusted under the best working condition of the LED light module, all the street lamps within the area can be maintained by only using spares and spare parts of few light-emitting modules, and the overhead working labor intensity is smaller.

Description

technical field [0001] The invention relates to an LED road lighting fixture, in particular to a combined LED road lighting fixture that can be combined or adjusted by using a standardized light-emitting module and a power supply module according to use requirements and environmental characteristics. Background technique [0002] Known LED road lighting fixtures usually adopt an "integrated" structure, that is, the light source and power supply are packaged in the lamp housing, and a heat sink is provided on the outer surface of the lamp housing. The "integrated" LED road lighting fixtures have at least the following defects: There may be different brands, different specifications, and different shapes of the above-mentioned lamps in the same area, so the street lamp management department must have various spare parts, spare parts and corresponding maintenance skills In order to ensure the normal operation of the street lamp. When the lamp is abnormal, it is usually necessa...

Problems solved by technology

The "integrated" LED road lighting fixtures have at least the following defects: There may be different brands, different specifications, and different shapes of the above-mentioned lamps in the same area, so the street lamp management department must have various spare parts, spare parts and corresponding maintenance skills In order to ensure the normal operation of the street lights

Invention patent application 200710144091.6 has at least the following problems: one is limited by the installation position in the base, if it is necessary to enhance the lighting effect, the existing standardized LED light source module unit with higher power can only be replaced. LED light source module unit, which will cause unnecessary cost increase; the second is that the heat dissipation effect of the standardized LED light source module unit will be reduced due to the shielding of the base, upper cover, and waterproof cover
