Abstract

The embodiment of the utility model discloses an LED lamp, which comprises a reflection sheet, an LED, a printed circuit board and a lamp bracket, wherein the LED is arranged on the printed circuit board; the reflection sheet is stuck on one surface of the printed circuit board; the reflection sheet has the reflection function and is provided with a hole used for containing an LED outline; and the other surface of the printed circuit board is arranged on the lamp bracket. In the utility model, as one surface of the printed circuit board is stuck with the reflection sheet, and the other surface thereof is in contact with the lamp bracket, thereby not only enhancing the lighting effect of the LED lamp, but also helping the heat dissipation of the LED lamp. In addition, all the parts are connected tightly in the whole installation process, in particular to the installation of a lampshade and the printed circuit board, wherein the lampshade and the printed circuit board are fastened by a common screw and are limited by the self-structures (inside and outside necks on the lamp bracket), therefore, the connection of the lampshade and the printed circuit board is more compact and reasonable.

Description

A kind of LED lamp

Technical field

The utility model relates to the LED lamp and makes the field, more particularly, relates to a kind of good LED lamp of light efficiency that strengthens.

Background technology

People have understood the ABC that semi-conducting material can produce light before 50 years, and first commercial diode results from nineteen sixty.LED is the abbreviation of English light emitting diode (light emitting diode); its basic structure is an electroluminescent semi-conducting material, places on the leaded shelf, uses epoxy sealing then all around; play the effect of protection internal core, so the anti-seismic performance of LED is good.The wafer that the core of light emitting diode is made up of p type semiconductor and n type semiconductor has a transition zone between p type semiconductor and n type semiconductor, be called p-n junction.In the PN junction of some semi-conducting material, the minority carrier of injection and majority carrier compound tense can discharge the form of unnecessary energy with light, thereby electric energy directly is converted to luminous energy.PN junction adds backward voltage, and minority carrier is difficult to inject, so not luminous.This diode that utilizes the making of injection electroluminescence principle is generally called LED light emitting diode.When it is in the forward duty (two ends add forward voltage), when electric current flowed to negative electrode from the LED anode, semiconductor crystal just sent the light from ultraviolet to infrared different colours, the power of light and current related.

The internal characteristics of LED lamp has determined that it is that optimal light source removes to replace traditional light source, and it has purposes widely.Volume is little, and LED is that a very little wafer is encapsulated in epoxy resin the inside basically, thus its very little, very light; The low LED power consumption of power consumption is very low, and in general the operating voltage of LED is 2-3.6V, and operating current is 0.02-0.03A, and in other words: the electricity that it consumes is no more than 0.1W; Long service life under appropriate electric current and voltage, can reach 100,000 hours high brightness, low in calories the service life of LED; Environmental protection, LED is made by nontoxic material, and containing mercury unlike fluorescent lamp can pollute, and simultaneously LED also can recycling; Sturdy and durable, LED is encapsulated in the epoxy resin the inside completely, and it is all firmer than bulb and fluorescent tube.Also do not have loosening part in the lamp body, it is non-damageable that these characteristics make that LED can be described as.Therefore, the LED lamp is favored by the people more and more, but because present LED lamp white paint reflecting effect is not good, has influenced the light intensity effect of LED lamp.Now be badly in need of the effective LED lamp of a kind of light intensity.

The utility model content

In view of this, the utility model provides a kind of LED lamp, to realize strengthening the strong purpose of LED light.

For achieving the above object, the utility model provides following technical scheme:

A kind of LED lamp, comprise: reflecting piece, LED, printed circuit board and lamp bracket, wherein, described LED is installed on the described printed circuit board, described reflecting piece is installed on the printed circuit board, this reflecting piece has reflection action, and is provided with the hole that holds described LED profile, and described printed circuit board is installed on the described lamp bracket.

Preferably, in above-mentioned LED lamp, described reflecting piece is plastic cement or metal material.

Preferably, in above-mentioned LED lamp, described lamp bracket is provided with draw-in groove.

Preferably, in above-mentioned LED lamp, described draw-in groove comprises inner draw-in groove and outside draw-in groove.

Preferably, in above-mentioned LED lamp, be equipped with printed circuit board on the described inner draw-in groove.

Preferably, in above-mentioned LED lamp, described printed circuit board is fixed on described printed circuit board on the described lamp bracket by screw.

Preferably, in above-mentioned LED lamp, also comprise lampshade, described lampshade is installed on the described lamp bracket.
