Abstract
The invention relates to the field of LED lamp structure design, and discloses an LED lamp structure with relatively high light emission efficiency. The LED lamp structure comprises a lampshade, a radiator, a light source, a circuit board and a reflection plate, wherein the top of the radiator is covered with the lampshade; an internal space is formed between the lampshade and the radiator; the light source, the circuit board and the reflection plate are arranged inside the internal space; the circuit board is mounted at the top of the radiator; the light source is mounted at the top of the circuit board; the reflection plate is arranged between the light source and the circuit board. By adopting the technical scheme of the embodiment of the invention, since the reflecting plate is arranged between the circuit board and the light source, the light emission route of the light source can be changed, so that the lighting angle of a lamp is increased, and meanwhile the light emission flux of the lamp is also increased.
Description
Technical field
The present invention relates to LED lamp structure design field, particularly a kind of LED lamp structure of higher luminous efficiency.
Background technology
Light emitting diode (Light-Emitting Diode, LED) is a kind of semiconductor electronic component that can be luminous.This electronic component occurred as far back as 1962, and can only send the ruddiness of low luminosity in early days, develop other monochromatic versions afterwards, the light that can send even to this day is throughout visible ray, infrared ray and ultraviolet, and luminosity also brings up to suitable luminosity.And purposes is also by the beginning as indicator lamp, display board etc.; Along with the continuous progress of technology, light emitting diode has been widely used in display, television set daylighting decoration and illumination.
Say from circuit, it is the one of semiconductor diode, electric energy conversion can be become luminous energy.Light emitting diode is the same with general-purpose diode to be made up of a PN junction, also has unilateral conduction.After adding forward voltage to light emitting diode, be injected into the hole in N district from P district and be injected into the electronics in P district by N district, near PN junction in several microns respectively with the electronics in N district and the hole-recombination in P district, produce the fluorescence of spontaneous radiation.In different semi-conducting materials, electronics is different with the energy state residing for hole.The amount discharged when electronics and hole-recombination is different, and the energy discharged is more, then the wavelength of the light sent is shorter.
The principal element affecting LED lamp luminous flux comprises the reflective and transmission capacity of associated materials in the luminous flux output of light source, light fixture.Obviously there is the defect of above-mentioned factor in existing LED lamp, causes luminous efficiency low.
Summary of the invention
The goal of the invention of the embodiment of the present invention is the LED lamp structure providing a kind of higher luminous efficiency, applies the luminous flux that this technical scheme can improve LED lamp, improves luminous efficiency.
In order to realize foregoing invention object, complete skill scheme of the present invention is:
A LED lamp structure for higher luminous efficiency, comprises lampshade, radiator, light source, circuit board, reflector; Described lampshade is at the top of described radiator, and form inner space between the two, described light source, circuit board and reflector are arranged on described inside spatially; Described circuit board is arranged on the top of described radiator, and described light source is arranged on the top of described circuit board; Described reflector is arranged in the middle of described light source and described circuit board.
