Description
Technical field
The invention belongs to optical field, more particularly to a kind of lens that the reduction of 1 paster LED lamp reflectance is closed to 3.
Background technology
The principle of luminosity of LED is by compound semiconductor, by the combination in electronics and hole, superfluous energy by electric current
To in the form of light disengage, reach luminous effect.For visible ray light-emittingdiode wavelength in 400-700 nm.It is existing
Some LED illumination light sources are broadly divided into two kinds of direct plugging-in and patch-type.
Straight cutting LED is also referred to as plug-in unit light emitting diode, is a kind of partly leading for solid-state that can convert electrical energy into visible ray
Body device.The encapsulation of direct insertion LED is in the form of embedding.The process of embedding is first to inject liquid epoxy in LED forming cavities
Resin, is inserted into the good LED support of pressure welding, is put into baking oven and allows after epoxy resin cure, and LED is detached i.e. from die cavity
Shaping.
It with soft pcb board is substrate that paster LED is, high brightness paster LED is uniformly arranged as illuminator, illuminator
In stripe shape pcb board front, it is connected with each other using water joint, is adapted to SMT processing, reflowable weldering, adopting surface mounted LED is solved well
The problems such as brightness, visual angle, flatness, reliability, uniformity, relative to other packagings, it has, and vibration resistance is strong, weldering
The advantages of point defect rate is low, high frequency characteristics is good, it encapsulates more LED chips on less area, adopts lighter PCB
And reflector material, show that reflecting layer needs the epoxy resin of filling less, by removing heavier carbon steel material pin, reduce
Size, can mitigate half by product weight easily, and volume and weight only has 1/10 or so of traditional inserting element, using paster
After formula encapsulation, electronic product volume-diminished 40% one 60%, weight saving 60% one 80% finally makes using more perfect.
With the progress of scientific and technological level, the quality of life of people also more and more higher, the quality requirement to showing and illuminate is also more next
It is higher.Traditional straight cutting LED component is gradually replaced by paster LED.
When 3 close 1 SMD lamp is used in display field, in addition to needing to consider the raising of brightness and the change at visual angle, also need
Guarantee the reflective property of the SMD lamp of 3 conjunction 1.Existing lens itself are in order to reduce light loss, and what is be commonly designed is relatively smooth, so instead
Light is than larger.Display device contrast is affected during sun light direct beam.
For this purpose, prior art generally reduces the reflected light that sun light direct beam brings by increasing sky shade.But, for
The countries such as Sweden, Norway, the Finland of high latitude area, such as Northern Europe, shine upon the situation that parallel radiation occurs.This feelings
The function of sky shade just seems very little under condition.In addition, above-mentioned technology mainly for SMD lamp pair as if relatively old design
The SMD lamp of 3528 encapsulation.This kind of SMD lamp is gradually replaced by new design.
The content of the invention
