Abstract
The invention involves an integrated LED lamp (1) whose hood (3) for shielding sun light is detachable and adjustable according to its necessity. Even after the hood is attached to the lamp case, its length is easily altered. A waterproof structure, which is provided by fixing an LED substrate (2) to the case (4) by inserting the hood (3) to the case (4) and printing sealing material (11) at a circumference of the LED substrate (2), edges (32) of the hood, and grades (47) of the case, prevents potting material from leaking into an inner space (44) of the case and reduces manufacturing process for airtight sealing. Further, a through hole (2) on the LED substrate (2) for a pair of leads (13) of an LED (10) is tilted from the horizontal direction by a predetermined degree resulting in an expanding light distribution characteristic to the direction perpendicular to the connecting line k. Also, the direction of light distribution can be controlled by altering the tilt angle of the through holes (20) according to necessity. Further, the integrated lamp (1) has a controlled LEDs arrangement of each color of red, blue, and green in a 5.times.5 matrix structure assuring homogeneous luminou…
