Embodiment 1

[0034] The method for manufacturing an LED floodlight provided in Embodiment 1 of the present invention includes the following steps:

[0035] Determining the length, width and area of ​​the rectangular surface to be irradiated, the focal length and diameter of the lens 4 to be used by the LED floodlight, the vertical distance between the LED floodlight and the surface to be illuminated, and the projection angle of the LED floodlight;

[0036] According to the size and area of ​​the rectangular surface to be irradiated, the focal length and diameter of the lens 4 to be used by the LED floodlight, the vertical distance between the LED floodlight and the surface to be irradiated, and the imaging principle of the lens 4, the ideal illumination state is calculated ( That is, when the projection angle is 90°), the overall dimensions of the light board 1;

[0037] Make an experimental light source according to the focal length and diameter of the lens 4 used by the light board 1 and...

Embodiment 2

[0052] The method for manufacturing an LED floodlight provided by Embodiment 2 of the present invention includes the following steps:

[0053] Determining the length, width and area of ​​the rectangular surface to be irradiated, the focal length and diameter of the lens 4 to be used by the LED floodlight, the vertical distance between the LED floodlight and the surface to be illuminated, and the projection angle of the LED floodlight;

[0054] According to the size and area of ​​the rectangular surface to be irradiated, the focal length and diameter of the lens 4 to be used by the LED floodlight, the vertical distance between the LED floodlight and the surface to be irradiated, and the imaging principle of the lens 4, the ideal illumination state is calculated ( That is, when the projection angle is 90°), the overall dimensions of the light board 1;

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 an LED floodlight manufacturing method and relates to the field of LED lamps. The LED floodlight manufacturing method includes the following steps that the face to be irradiated is irradiated with a test light source at the projection angle of an LED floodlight according to the perpendicular distance between the LED floodlight and the face to be irradiated, the size of each side of a trapezoid appearing after the irradiation and the size of the face to be irradiated are compared to calculate the distortion ratio, and the size of the corresponding sides of a lamp panel is corrected through the distortion ratio; the manufactured lamp panel is installed in the LED floodlight, and the LED floodlight is assembled. The LED floodlight manufacturing method has the advantages that the LED floodlight manufacturing method and the LED floodlight manufactured with the method are provided, the lamp panel is calculated and manufactured according to the shape of the irradiation area so that the LED floodlight can define a required shape through irradiation, different market demands are met, the demanded quantity is large, excessive places will not be irradiated, power consumption of the LED floodlight is reduced, using cost is saved, lighting quality is improved, and waste of electric resources is reduced.

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...
