Projection Lamp Identification Techniques - Projection, Projector Bulbs - And Sound Recording

Currently on the market Projector Categories as light bulbs

, quite a mixed bag, counterfeit products lawless. What makes this market to become so?

My opinion, one is because Projection Bulb is Projector The main Fitting Is also the most expensive projector Consumables , The price of a light bulb may reach 2000 thousand 6000 thousand dollars, the price of ordinary bulbs to replace about 3,000 yuan, so the user is concerned, no doubt each bulb replacement cost is another big investment in a number of projectors When buying cheaper, but in the next few years, the cost will spend more to maintain, so the use of light bulbs and the cost of goods sold has been long plagued projector users, particularly the situation of complete dependence on imports , the light bulb price is gradually rising. Many projector users are: affordable could not afford, so relatively low popularity of the poor quality of bulbs.

Followed by the industry to develop the light bulb's warranty period is short, though now some manufacturers such as ViewSonic, Hewlett-Packard has developed some models for 2-year bulb warranty, but most of the other six months are the warranty. Current policy is not perfect, not very clearly defined bulb warranty period, so all businesses have the final say.

Furthermore, manufacturers of service coverage and service capacities. And remote areas in the west, the user can not get a good reliable, secure, from the original service support. For those in remote areas of the users, the bulb is broken, or aging, and can change in time from the local purchase is very important that false force separate ways only an opportunity.

UHE lamp

Also, the projection of the market at present are mainly high pressure mercury lamps and metal halogen lamp bulb into two categories. We usually see UHE, UHP and UMPRD other bulb is divided into different brands, such as UHE is Epson (Eposn) of the projector bulb model, UHP is Philips (PHILIPS) projector lamp brand, UMPRD / UMVRD / NSH is Japan's excellent blog busy lamp type, SHP Phoenix's light bulb model in Japan, SHL is the GE light bulb model, VIP, Germany Osram light bulb model. Among the many types of light bulbs, use was most of the UHE lamp, UHP lamps and metal halogen bulbs of these three, however, the core technology of these bulbs are a handful of corporate hands, the global manufacturer of projector bulbs are only PHILIPS ( UHP), USHIO (UMPRD), OSRAM (VIPR), Panasonic (UHE), MSCR, etc. 45 Therefore, the monopoly of technology leading to high prices and the emergence of profits and also lead to counterfeiters rush.

UMPRD bulb

Also introduced by the projector manufacturer's original light bulb, a clear sign that it is a manufacturer of packaging and special lighthouse logo, the industry as "the original packet." Original packet is the projector manufacturers such as EPSON, NEC, SONY, SANYO and others such as the light bulb manufacturer PHILIPS, OSRAM and other special orders to the projector after the bulb (light bulb manufacturers produce only light bulbs, is not responsible for Lighthouse and packing boxes), according to Stands and different models produce boxes, and then sold through formal channels to the user's.

Its quality and service life have been rigorously tested product quality is guaranteed, basically to achieve the projector manufacturer said the average usage time. The author recommends that users of such lamps as the preferred. However, many channels, the projector bulb manufacturers through Agents , Dealers layers plus profit, the price has been sky high, and very little supply, it is difficult to buy. Also precisely because of this, leading to a variety of non-regular light bulbs to exploit any tiny opening, penetrate to every corner of the market.

If you accidentally purchase a replacement or informal products, will lead to the projector using the effect of poor, life is short, even bursts may occur, so we must be careful identification. So far the projector lamp is also dependent on imports, so they become the target of public criticism JS fake fake. Now I will focus on the UHP bulb fake and real goods identification guide to what I hope we can comprehend by analogy, giving top priority.
