Problems solved by technology

However, the existing LED lamps, including general lighting lamps and accent lighting lamps, generally have the problems of low light energy utilization efficiency and obvious glare.
Among them, the light of LED surface light source is soft, but the light energy utilization efficiency is low, and the luminous efficiency is not high, which has become a prominent problem in the popularization of LED surface light source.

Embodiment Construction

[0021] The structure of the surface light source of the present invention is as figure 1 As shown, it is mainly composed of a radiator 1, a light source 3, a light guide plate 5, a housing 6 and a power supply (not shown in the figure). The radiator 1 is locked on the casing 6 by screws 7 , the metal substrate 2 is placed on the radiator 1 , and a copper-clad circuit is made on the upper surface of the substrate 2 . The positions of the pads of the circuit are in an equilateral triangular array, so when the light sources 3 are mounted on it, they can be arranged in an equilateral triangular array, and the light emitting direction of the light sources 3 faces upward. A light guide plate 5 is installed on the heat sink 1 and the light source 3, and the light guide plate is glued on the housing with AB glue. The distance between the light guide plate 5 and the plane where the light source 3 is located is equal to the product of the cotangent of the 70% light intensity angle of t...

Abstract

The invention discloses a surface light source. A radiator (1) and a substrate (2) are arranged at lowermost positions; a copper-coated circuit is arranged on the substrate (2); a light source (3) is distributed and welded on the substrate in the form of regular triangle; a light guide plate (5) is arranged on the plane of the light source (3); the distance between the light guide plate (5) and the plane of the light source (3) is 0.5 to 3 times that of the distance between adjacent light sources (3); the lower surface of the light guide plate (5) is provided with mesh points (4); and the distance between adjacent mesh points is less than 0.3 millimeter. Due to the adoption of a combination method, the working temperature of the LED light source can be lowered, light color of the LED light source (3) is kept consistent and high light energy conversion efficiency is kept in addition of the realization of soft light.

Description

technical field [0001] The invention relates to a soft and efficient LED surface light source. Background technique [0002] With the rapid development of the global economy, human beings have an increasing demand for energy and resources, which has also caused the increasing shortage of energy and resources. At the same time, carbon dioxide and other harmful substances emitted during human production and utilization have caused various problems such as global warming and environmental pollution. Most of the energy is finally converted into electrical energy for direct use by humans. Among them, the electric energy used for lighting accounts for a considerable part of human electricity consumption. If new lighting fixtures such as LED lamps are used to replace traditional incandescent lamps, energy consumption and environmental pollution can be significantly reduced. However, the existing LED lamps, including general lighting lamps and accent lighting lamps, generally hav...
