Q:What's the market for advertising projection lights in China?

The projection lamp can be said to be low cost, high profit, a 400 yuan of the lamp lights, but the cost of tens of dollars or even lower, but also some high light value!

Q:How to identify projection light bulb true and false?

The second category is from other sources to live on the market projection bulb manufacturers produce bulbs, such as PHILIPS, OSRAM, etc., characterized by no lamp rack, the industry called "original bulb."". The original light bulb is generally smuggled into the country, so the price is lower than the original one. What's on the market today is basically this "original" bulb". Compared with "original bulb", the service life of "original bulb" is not far from each other. But some of the so-called "original bulb" is the manufacturer's defective or projector manufacturers test light bulb, it is difficult to judge the simple appearance, life expectancy is relatively short, in the purchase must pay attention to avoid being deceived.

Q:Where can I buy the projecting lights of the four seasons Star Projector in Guangzhou?

The sphere is made of plastic film with black film on it...... The effect is poor. After I assembled it myself, I saw the effect and threw it directly into the bin.

Q:The assembly of four star projection lights?

Taobao should have a method of assembly, and should have an explanation, although it is in Japanese, but the diagram should be easy to understand, it is recommended to find a folding web site to see what those dashed lines mean when assembling

Q:The effect is dynamic, and the fish can swim.People through the projection range, the screen will appear corrugated, this is related to the light, or with the set of lights into the file related to, and the file Related words, what format files do you need?

The projector can do it ~ I haven't heard of excessive type ~ software doesn't know ~!

Q:How long has the projector been used?

Different projectors use different time to look at the bulb. For example, the projector can hold the panel directly. The arrow up button for more than 30 seconds, the bulb will jump out of use time.Some projector menu options, can view the projector bulb using time system settings, but if before meeting the outage situation during use, so the use of time will not be recorded, so it is not very accurate.Generally, the brightness of the projector bulb will gradually decrease with the increase of the use time, and choose the light bulb with good appearance and brightness.

Work according to built-in program

Q:What is the relationship between the power of projection lamp and luminous flux and luminous efficiency?

Start with a formula: light effect = total luminous flux / bulb power. From this formula, we can see that the higher the luminous efficiency is, the stronger the ability of the lighting equipment to convert electric energy into light energy, that is, the higher the light efficiency is, the more energy saving.At the same time, the above formula is deformed: total luminous flux = bulb power * luminous efficiency. That is, under the same power, the higher the light value, the greater the brightness.If some businesses only promote their projection lamp power is relatively large, but the light effect is relatively low, so the relative brightness is relatively small, which is why we have the same brightness power products from different manufacturers is not strengthConsistent cause. Therefore, customers in the purchase of recommended projector products, but also pay attention to light efficiency of this parameter.

Q:Can you tell me how to judge the quality of LED projector?

LED washing wall lamp quality is good or bad, Crystal Valley lighting recommend you can refer to the following points to judge, thank you!1, structure and function? connect the box with the left and right side cover flat, the gap between the two is not greater than 0.6mm? the box and the track are well assembled. The spacing of the conductive plate meets the requirements and is in good contact with the track conductive strip? electric box and rail installation; plastic and conductive sheets without scratch and deformation; and normal conduction.? pull up the U frame positioning slider, the lamp body can rotate around the U frame up and down 90 degrees. After positioning, pull down the positioning slider, the lamp can stay in any position, and the positioning is accurate and firmThree - oblique cylinder by clip is fixed on the lamp tube mouth, compact and firm.? silicon sleeve shall not be out of the hollow pill, the net cover of the back net is stuck to the silicon sleeve and the outlet, so as to effectively prevent pulling
