Reflection surface self-cooling LED indoor illumination device

Abstract

The invention provides a reflecting surface self radiating LED indoor illuminating lamp, which comprises a circuit board, an LED and a reflecting shade for reflecting an LED light source; the reflecting surface of the reflecting shade is a convex surface; the LED is arranged on the circuit board, and a clearance is reserved between the circuit board and the convex surface; the LED is positioned between the convex surface and the circuit board; one side of the circuit board facing to the convex surface is coated with a reflecting layer and the circuit board is an aluminum substrate; the LED is directly welded on the aluminum substrate; and the circuit board is connected with a circuit power supply through a conducting wire; and the circuit power supply is separated from the circuit board. The convex surface of the invention disperses the light from the LED, so that the convergent light is dispersed, the irradiation range is enlarged, and light is uniform in spacial range with the reflection of the reflecting layer. The LED is positioned between the convex surface and the circuit board, the aluminum substrate is exposed in the air so as to form good heat radiation and air convection; and the illuminating lump has the advantages of simple structure, good radiation effect, uniform illumination, and the like.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a reflective surface self-radiating LED indoor lighting. Background technique [0002] With the development of light-emitting diode technology, high-power LED technology has become increasingly mature. It has many advantages such as high luminous flux, long life, high reliability, and energy saving. It is the most potential light source to replace the existing lighting source. Existing LED lamps generally use multiple power LEDs in one lamp, so the heat dissipation of LEDs becomes an important factor affecting the use status and lifespan of LED lamps. However, the existing LED lamps generally adopt a closed structure, and the heat of the light source and the driving power cannot be dissipated in a timely and effective manner. Although some lamps also design a special heat dissipation structure, the structure is usually complicated and the heat dissipation effect is not good....

Problems solved by technology

However, the existing LED lamps generally adopt a closed structure, and the heat of the light source and the driving power cannot be dissipated in a timely and effective manner. Although some lamps also design a special heat dissipation structure, the structure is usually complicated and the heat dissipation effect is not good.

In addition, in the existing high-power LED lamps, the LED light source is generally set directly toward the ground, and the light emitted by the LED is uneven, which is irritating to the human eye and seriously affects the lighting effect of the LED lamp. Long-term viewing may easily cause visual fatigue. even vision loss
