Description
Technical field
The present invention relates to a kind of lamps and lanterns, the LED light to shine more particularly, to a kind of no dark space wide-angle.
Background technology
The various lamps and lanterns extensive use to be shone with LED, LED are solid chip light emittings, and general area is several flat in zero point
Square millimeter is between several square millimeters, and thickness is between tens to hundreds of microns.LED chip must be packaged into lamp bead or other shapes
Shape could use.Surface-mount LED lamp pearl is the most widely used packaged types of LED, because price is low, performance is good, has been widely used in
In LED Straights lamp, LEDbulb lamp and other LED illumination lamps.
Surface-mount LED lamp pearl it is small-sized, only several millimeters long and wide, thickness only has 1 millimeter, even lower than 1 milli
Rice, and power is usually less than 1 watt.And LED Straights lamp such as T8 fluorescent tubes, length are generally up to 1200 millimeters or even longer；
The diameter of LEDbulb lamp also has tens millimeters, it is therefore desirable to using substantial amounts of Surface-mount LED lamp bead string parallel connection in the circuit board, and
Light distribution is carried out to Surface-mount LED lamp pearl.Generally only 120 degree of the light emitting angle of Surface-mount LED lamp pearl, causes LED Straights lamp and LED
The light emitting angle of bulb lamp is small, it is difficult to which the full angle for meeting LED Straights lamp and LEDbulb lamp shines demand.
In existing LED Straights lamp such as T6 fluorescent tubes and T8 fluorescent tubes, Surface-mount LED lamp pearl serial or parallel connection or connection in series-parallel are in length
On the wiring board of strip structure, wiring board is generally aluminum substrate or epoxy resin glass-fiber-plate, and wiring board is glued by card slot or directly
It is connected on the inner wall of fluorescent tube.Since Surface-mount LED lamp pearl is arranged in a straight line in the circuit board, and Surface-mount LED lamp pearl is dotted luminous, hair
Angular only has 120 degree, therefore the wiring board region between Surface-mount LED lamp pearl is there are light and shade striped, and the presence of light and shade striped
The light emitting angle of LED Straight lamps is not only influenced, but also the uniformity of Integral luminous can be influenced.In existing LEDbulb lamp,
Surface-mount LED lamp pearl serial or parallel connection or connection in series-parallel are on the metal circuit board of circular configuration（Metal such as aluminium, copper etc.）, metallic circuit
Plate installation is connected on a heat sink with lamp cap.Since Surface-mount LED lamp pearl is that dotted luminous and light emitting angle only has 120 degree,
There are dark space, light emitting angle is difficult to reach 300 degree or more the lamp holder end of LEDbulb lamp.
In order to expand the light emitting angle of existing LED Straights lamp and existing LEDbulb lamp, often using following two
Method, first method are that Surface-mount LED lamp pearl is mounted in stereochemical structure or increases LED light using reflex reflector etc.
Light emitting angle, but this can cause LED lamp structure to become complicated, and cost and weight increase；Second method is in LED straight tubes
One layer of photodiffusion material is applied on the tube inner wall of shape lamp and on the inner wall of LEDbulb lamp, however this method is difficult to
Eliminate dark space, it is difficult to improve light emitting angle.
The content of the invention
The technical problems to be solved by the invention are to provide one kind and dark space, and the LED light that light emitting angle is big are not present.
