Embodiment 3

[0083] Embodiment 3 is a method for making an LED floodlight with a rectangular projection area:

[0084] Now assume that the design of LED floodlights for lighting a single-column rectangular billboard with a specification of 6 meters x 18 meters is an example:

[0085] According to the distance of 3 meters, the billboard is vertically divided into 6 a×b rectangular lighting areas, where a is 3 meters and b is 6 meters. The floodlights of each design only need to meet the requirements of this 3m x 6m lighting area;

[0086] The light bracket is installed vertically on the bottom and top of the billboard (if installed at the bottom, the light will project upwards; if installed at the top, the light will project downwards). This example takes the installation at the bottom as an example. The effective length of the lamp bracket is set to v, that is, the vertical distance between the lens 4 plane of the floodlight and the plane of the billboard;

[0087] It is known that the f...

Abstract

The invention provides a method for manufacturing an LED floodlight, which relates to the field of LED lamps, comprising the following steps: irradiating the surface to be irradiated with an experimental light source according to the vertical distance between the LED floodlight and the surface to be irradiated, and the projection angle of the LED floodlight , calculate the distortion ratio by comparing the size of each side of the irradiated trapezoid with the surface to be irradiated, and use the distortion ratio to correct the size of the corresponding side of the light board; install the manufactured light board in the LED floodlight , Assemble the LED flood light. The beneficial effect of the present invention is to provide a method for manufacturing LED floodlights and the LED floodlights produced by the method. According to the shape of the irradiated area, the lamp board is calculated and manufactured, so that the LED floodlights can irradiate the required The shape meets the needs of different markets, and the demand is large. At the same time, it will not illuminate redundant places, saving the power consumption of LED floodlights, saving the cost of use, improving the quality of lighting, and reducing the waste of power resources.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to a method for manufacturing an LED floodlight. Background technique [0002] The common LED floodlights currently on the market are usually composed of five parts: light source, reflective surface, protective glass, electrical components, and housing. The light sources used include metal halide lamps, LED integrated light panels, etc. Its characteristics are: the projected light forms a fan-shaped irradiation surface on the surface of the illuminated object, and the projected fan-shaped irradiation area is inconsistent with the rectangular (or approximately rectangular) lighting object, resulting in more waste of light and damage to adjacent non- The light pollution in the lighting area leads to the waste of light energy and corresponding waste of power resources. Contents of the invention [0003] The purpose of the present invention is to provide a method for manufacturing an LED fl...
