Problems solved by technology

However, due to the small light-emitting point and beam angle of the light-emitting diode, the light intensity of the light-emitting diode is usually relatively concentrated. If the maximum light intensity distribution is not handled properly, it will easily cause glare to the observer.
The glare will not only reduce the working efficiency of the light-emitting diodes, but also cause adverse reactions such as visual fatigue and headaches for the observers.
Therefore, if the glare problem of the light-emitting diode is not solved, it is not conducive to promoting the application process of the light-emitting diode in indoor lighting.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific embodiments with reference to the accompanying drawings.

[0013] Figure 1 to Figure 3 Shown is the LED lamp in the first embodiment of the present invention. The LED lamp includes a cover 10 , a light guide rod 20 and two LEDs 30 (only one of the LEDs 30 is visible).

[0014] The light guide rod 20 is in the shape of a vertical cylinder, including a cylindrical body 23, a receiving hole 21 formed in the center of the two ends 22 of the body 23, and a plurality of grooves 24 formed on the outer surface of the body 23. . The two LEDs 30 are installed in the receiving holes 21 of the two ends 22 respectively. The diameter of the receiving hole 21 along the radial direction of the main body 23 and the depth along the axial direction of the main body 23 can vary according to the size of the LED 30 , so as to properly accommodate the LED 30 therein. The two end faces 22 of the light guide ...

Abstract

The invention relates to a light-emitting diode light fitting which comprises a cover body and a plurality of light-emitting diodes. A light guide stick is arranged in the cover body; the light-emitting diodes are respectively arranged on both ends of the light guide stick; the light guide stick can be made of materials which can transmit light; a plurality of debosses or bulges are formed on the outer surface of the light guide stick; and light emitted by the light-emitting diode goes through the light guide stick and goes out of the outer surface of the light guide stick. The light-emitting diode light fitting can produce good light radiating effect, has soft illumination effect, reduces glare, and is beneficial to indoor illumination.

Description

technical field [0001] The invention relates to a lighting device, in particular to a light-emitting diode lamp suitable for indoor lighting. Background technique [0002] Light Emitting Diode (Light Emitting Diode) uses the change of energy band level when electrons and holes in semiconductor materials are combined to release energy in the form of light. Because light-emitting diodes have the advantages of small size, long life, low driving voltage, fast response speed, and good shock resistance, they have been widely used in various fields such as advertising boards, traffic signs, and daily indoor lighting. [0003] However, the indoor environment is the environment where people live and work most of the time. People have relatively high demands on the indoor lighting environment. In normal indoor work or activities, not only sufficient luminous flux is required, but also luminous flux in the field of view is required. The environment must not have glare. However, due t...
