Besides its physical size, the focal length defines the critical property of a lens or mirror. We will discuss the importance of the focal length a bit later, but first let us look at the mathematical definition that directly affects how these lenses/mirrors are made. The focal length turns out to be:

During this process, we take the pleasure to assist selecting the proper products, do the light distribution design through Dialux with our IES file. And in cases we have to produce some customized items .

where "n" is the index of refraction of the lens glass, f is the focal length and r is the radius of curvature of the lens, which is positive in the case of a convex lens (negative in the case of concave mirrors, which we will not cover in detail). This radius of curvature can be seen clearly below for a biconvex lens geometry (the "bi" denotes the lenses are double sided with the same curvature).

The rise of online retail has totally transformed the face of business; The Covid-19 pandemic proved that unexpected and irresisitable external force could badly disrupt your stable supply chain operation; Shortage of supply of some key conponents like ICs because of the political level factor really delays the production process.Contractors or buyers learned from such experience and raised their expectation of faster delivery or just purchased from the enventory supplier.

Since we are now looking at ray diagrams, let us talk about the rules of how the rays work. We choose to show all rays leaving the head of the object (arrow seen in red above), although any other position on the object would work just as well.

We recognize that most people do not use their lighting systems 24 hours a day, and would love to match our LED’s longevity data with a warranty that fits the majority of our customers’ use cases. For that reason, we offer an industry topping (7) year warranty on most of our LED strip and linear lighting products.

We can see that the triangles Δ{ABC} (this denotes the triangle that has vertices at points A, B, and C) and Δ{ADE} must be similar because they are both right triangles, and the angle at point C in Δ{ABC}, is the same as the angle at point E in Δ{ADE} since the lines |BC| (which denotes the line that runs from vertex B to vertex C) and |DE| are parallel. The line |AB| is equivalent to the object height, and the line |AD| is equivalent to the image height. Since we know that the triangles are similar, the ratios of corresponding sides must be equal. So we get,

Considering the application outdoor environment is much harsher than indoor, and also there are huge climate differences among different countries and districts, we are able to declare 5 basic 5 years warranty on the outdoor linear light products for restrict ambient working condition like -20℃ to 50℃， less than 12 hours a day. For specific applicatio project, wanrranty should be discussed before ordering agreement.

where ho is the object height and hi is the image height. Similarly we can manipulate equation (2a) by defining the magnification of the lens as:

Now let us create another pair of similar triangles in the image below. We can see that triangles Δ{123} and Δ{425} are similar triangles since the angle at point 2 for both triangles are clearly the same, while lines |13| and |45| are again parallel. The line |42| is equivalent to the object height and the line |12| is the sum of the object height and image height. Now we get the relationship,

3. A ray that passes from the object thought the focal point on the object side of the lens, will be parallel to the optical axis as it leaves the lens to form an image.

To focus images, the majority of telescopes encountered in optical astronomy use convex lenses that work through refraction, or concave mirrors that reflect light. Contrary to popular belief, the main purpose of a telescope is NOT to magnify objects, but to collect a larger amount of light by using lenses/mirrors that have a much larger area than the human eye.

Using our convex lens diagram, we can construct a simple mathematical relationship between do, di, and f by looking at various similar triangles we can see in the diagram below.

Presures or jobs are transmitted to the production or supply side. We would see and take this challenge into chance and have been carrying out several messures: No one is to stock key components like ICs, the PCBs and customized LEDs. No two is to concentrate our focus on the main products, led strip, neon led strip, led flex wall washer, linear inground light, linear wall washer, and LED linear pixel light. A narrower products portfolio cut down our inventory , but at the same time serves target clients better.

Now we define the common nomenclature used in geometrical optics. For the convex lens seen in the image below, we see the parameters do, di, and f . All of these are lengths measured with respect to the lens/mirror, where do is the "object distance", di is the "image distance", and f is the focal length. The diagram below is known as a ray diagram, where the object is the physical item we wish to focus using a lens/mirror, and the image is the place where the light would yield a crisp replica of the actual object. A solid line runs through the center of lens/mirror and is the optical axis along which the focal points lie. Note that the image appears inverted about the optical axis. Also note that this particular ray diagram is only true while the object remains farther from the lens than the focal point.

Yes, and neccessary. Beside we keep our client information as confidential, we will sign confidential agreement with client for their purchase, new product development, the collabration documents, and project protection.

by combining equations (2a) and (3) (I suggest you all do this step on your own to work your algebra muscles). The term $\frac{1}{f}$ is known as the optical power and is generally given in units of diopters, which are simply inverse meters. These are the units optometrists use to prescribe corrective lenses or contacts (in addition to other key numbers, such as the distance between your pupils if you are getting eye glasses).
