Description

A kind of LED bulb

Technical field

The present invention relates to technical field of lighting fixtures, is a kind of LED lighting bulb more specifically.

Background technology

LED is the abbreviation of English light emitting diode (light emitting diode), LED is a kind of semiconductor that electric energy can be converted into visible light, it has changed the luminous and energy-saving fluorescent lamp tricolor powder principle of luminosity of incandescent lamp tungsten filament, and adopt electric energy luminous, have long, numerous advantages such as light efficiency is high, radiationless, low-power consumption of life-span, along with the energy-conservation and proposition green illumination theory, LED is introduced in the lighting gradually as light source.

At present, the light emitting source that normal lighting lamps such as daily bulb, desk lamp are adopted is based on incandescent lamp bulb or fluorescent tube basically, yet, the electro-optical efficiency of incandescent lamp bulb and fluorescent tube is all lower, and its heat is big, and service life is short, generally only has about 3000 hours.

LED then can overcome above shortcoming, and its internal characteristics has determined that it is optimal light source:

(1) volume is little.LED is that a very little wafer is encapsulated in epoxy resin the inside basically, thus its very little, very light.

(2) power consumption is low.The LED power consumption is very low, and in general the operating voltage of LED is 2-3.6V.Operating current is 0.02-0.03A.In other words: the electricity that it consumes is no more than 0.1W.

(3) long service life.Because what the LED lamp adopted is direct current supply, so under appropriate electric current and voltage, can reach 100,000 hours the service life of LED.

(4) environmental protection.LED is made by nontoxic material, and containing mercury unlike fluorescent lamp can pollute, and LED also can recycling simultaneously.

(5) 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.

Because the significant advantage of LED some have also occurred with the bulb of LED as light source on the now domestic market, its basic structure roughly is divided into two kinds:

A kind of is the structure of imitation incandescent lamp, directly circuit board is placed on lamp holder inside, will make the cap part lengthening like this, thereby cause the length of radiator to shorten, influence the radiating effect of LED widely, thereby LED is damaged easily, influenced the service life of bulb;

Another kind is exactly that the lower end of radiator is provided with a groove, directly circuit board is put in the bulb from the bottom of radiator then, and then connection lamp holder, the shortcoming of doing like this is circuit board meeting double swerve in the groove of radiator, in transportation or loading and unloading bulb, damage circuit board possibly, thereby cause circuit board malfunctioning, damage bulb, dangerous more is, the connector or the electric wire of ifs circuit plate come off, and touch radiator, and the outer wall of bulb will be charged so, thereby bring injury to the person, security performance then can not guarantee.

In addition, the production and assembly of LED bulb are artificial operation substantially at present, because general lamp envelope design is simple, the structure that does not have rapid fixed position between the accessory, make production efficiency low, be difficult to realize large-scale batch process the in batches, and owing to there is not unified standard-required, workman's randomness is very strong, makes the quality of bulb to be protected, especially new workman, when mounted also can be owing to operate miss, damage the accessory of bulb, make production cost increase, can cause a lot of unnecessary loss to enterprise.

Summary of the invention
