LED daylight lamp without dark zones at two ends

Abstract

The invention relates to an LED (Light Emitting Diode) daylight lamp without dark zones at two ends. The LED daylight lamp comprises a heat radiator, a lamp plate provided with an LED device, a bar-type lamp cover and an end cover, wherein the bar-type lamp cover is in the shape of a curved surface in the width direction, and the two end parts of the bar-type lamp cover are also in the shape of the curved surface in the length direction, so that the light-emitting surface in the shape of a totally-closed curved surface is formed; an outer edge capable of being matched with the heat radiator and the end cover is arranged at the bottom of the curved surface; a lamp cover outer edge and a heat radiator matching edge are arranged on the end cover; a lamp cover outer edge is arranged on the heat radiator; the bar-type lamp cover is connected with the lamp cover outer edge of the heat radiator through the outer edge in a matched way and also connected with the lamp cover outer edge of the end cover in the matched way; and the heat radiator matching edge of the end cover is connected with inner mold cavities in the two ends of the heat radiator in the matched way. The problem of low lighting efficiency caused by the lamp head dark zones at the two ends of the conventional LED daylight lamp is solved through the lamp cover capable of emitting light from head to tail; the LED daylight lamp is convenient to process and manufacture and can be directly mounted on mounting surfaces such as a ceiling and a wall or suspended without an original daylight lamp bracket; the problems of complicated mounting and rigid and outdated shape in the prior art are also solved; and the technical progress is remarkable.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED fluorescent lamp without dark areas at both ends. Background technique [0002] Existing LED fluorescent lamps usually adopt the same shape and installation structure as traditional fluorescent lamps, and have lamp caps at both ends that protrude from the power connection column and can be connected with the lamp socket on the fluorescent lamp frame. The lamp cap of a general LED fluorescent lamp is formed by plastic injection molding, and the end is matched with the end face of the tubular lampshade and the end face of the radiator and fastened by screws. The lamp caps at both ends cover the end surfaces of the lampshade to form dark areas at both ends, which wastes the light at the ends of the lampshade, thus reducing the luminous efficiency of the entire lamp. During installation, the lamp holder of the LED fluorescent lamp should be connected with the lamp holder on the support, the sup...
