Problems solved by technology

But the LED lighting device of prior art will be widely used in the daily lighting lamps and lanterns that are closer to human body, such as book lamp (such as desk lamp), emergency lamp, camping lamp, family lighting lamp, also has following defect: the light source that a plurality of LEDs form They are all scattered point light sources, and the point light sources formed by each LED are very dazzling, which is particularly irritating to the eyes and even causes damage to the eyes. Therefore, it cannot be used for home and indoor lighting and the human body at present Nearer daily lighting fixtures; at the same time, because the light source composed of multiple LEDs is scattered and not concentrated, its light efficiency and brightness are not ideal

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] As shown in the attached picture.

[0016] The light-emitting device using LEDs in the present invention includes at least one white LED and a power supply. The power supply (not shown in the figure) generally adopts a DC power supply of 4.5 volts or 6 volts. If a battery of the prior art is used, an AC power supply of the prior art can also be used, such as 220 volts of commercial power after being transformed and rectified by a transformer. A 4.5 volt or 6 volt DC power supply, etc.

[0017] The light-emitting device using LEDs of the present invention also includes a cylinder of transparent material, that is, a lampshade. Stripes: there are evenly distributed axial stripes 8 on the inner wall circumference, that is, the vertical stripes shown in the figure, and there are evenly distributed annular stripes 2 on the outer wall circumf...

Abstract

The invention discloses a lighting device provided with LED, comprising at least one white LED (3), a power source, a transparent cylinder, two end plates (1) made from insulated material and two metal wires (6) whose two ends are fixed on two end plates (1) and connected to the power source. Two pins of LED (3) are connected to two metal wires (6). The transparent cylinder comprises a cylinder (4) whose inner and outer walls are arranged with crossed patterns or with smooth wall made from light diffuse resin. The invention can be arranged a plurality of LED (3) parallel connected on two metal wires (6). And the invention also comprises a reflective cup (10) at two ends of cylinder (4). The invention can form flexible light and high efficiency.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a lighting device using LEDs. Background technique [0002] Compared with incandescent lamps, fluorescent lamps have the advantages of power saving, high brightness, and light close to natural light, so it is an indisputable fact that fluorescent lamps gradually replace incandescent lamps. However, the disadvantages of fluorescent lamps are still obvious: they still consume more power, and the brightness is still not ideal. [0003] In recent years, another stepless lamp has appeared, which can overcome some shortcomings of incandescent lamps and fluorescent lamps, but its price is too expensive, so it is not feasible to popularize and apply it. [0004] In recent years, due to the successful development of (emitting) white light LEDs, LEDs have begun to enter the lighting industry. The Chinese name of LED is light-emitting diode, which belongs to cold light source. Compared with incandes...
