Problems solved by technology

However, since the illuminance is insufficient at a place far from the lighting device and at a place where the angle is deviated, the lighting device using LEDs has not become a general-purpose product, and there is room for improvement.

Embodiment 1

[0057] In order to obtain the same brightness as the general lighting fixture type 40 fluorescent lamp, such as Figure 4 As shown, 31 LEDs 13 are uniformly arranged in parallel on the aluminum substrate shown by reference numeral 14 . As the LED 13 , a 350 mA blue LED chip with a corner of 1 mm was used at a current of 217 mA. That is, the LEDs 13 with an angle of 1 millimeter are installed in a row at an interval of 5 millimeters, and surrounded by a light-transmitting body 11 with a light-diffusing effect, and then wires are used for electrical wiring so that it can pass through a constant current circuit and a rectifier. The diode is connected to a commercial power supply. The power consumption is about 1 / 2 of the lighting device of the same shape, and the service life should be more than 10 times.

[0058] As a diffusing agent for the light-transmitting body 11 with a light-diffusing effect, it is used as the first heating material to carry out the following preparation...

Abstract

The present invention provides a surface light-emitting lighting device which keeps the advantages such as long service life of LED and does not cause rapid illuminance reduction when the surface light-emitting lighting device is far from the LED or an angle is deviated from an illumination direction of the LED. Furthermore the surface light-emitting light device is provided with more than one LED structure parallelly. The lighting device is characterized by comprising more than one LED structures which are provided in parallel, and a transparent member which surrounds the whole bodies of the LED structure 1 and is formed through diffusing zinc sulphide (ZnS-Ag) compounds.

Description

technical field [0001] The present invention relates to a lighting device using LEDs, and more specifically, to a lighting device using LEDs whose illuminance does not decrease even if it moves away from the lighting device. Background technique [0002] There are many lighting devices using LEDs (for example, Patent Documents 1 to 2). In addition, as a substitute for a general lighting device, it is also known to imitate the appearance of a general lighting device, and diffuse the light transmitted by the LED through the light of the ground glass to emit light on the surface (for example, non-patent document 1). [0003] Compared with general-purpose lighting devices, these replacement lighting devices using LEDs have the advantages of less heat generation, lower power consumption, and longer life. Still a problem. In order to secure sufficient illuminance, arranging more LEDs in parallel and making them surface-emitting will increase the cost of the lighting device as a ...
