An LED chip loses luminosity over time. Even after this time, the projector still remains functional. Lifespan and luminosity of an LED drop if the operating temperature exceeds a limit. Efficient cooling therefore guarantees the reliability and brightness of a projection system.How are projection templates manufactured?We manufacture gobos according to customers' digital artwork files. The files are manually controlled and set up to meet the requirements of a high-power laser and printing. The artwork is then engraved or printed with high precision in special coated glasses.How can a distorted image be corrected?A distorted projection is caused by an oblique angle between the optical axis of the projector and the projection surface. If the projector cannot be positioned at right angles, it is possible to pre-distort the image on the gobo so that the result appears correctly.

Output power of the projector, 2. Ambient light intensity, 3. Distance, 4. Focal length of the lens, 5. Colour and texture of the projection surface, 6. Colour of the projection artwork. In difficult situations a test setup is essential.How to deal with the fault?A: If the fault happened within 3 months, and not caused by improper operation, we will send repair parts to you freely, or you can return the projector to us for repairing or exchanging a new one freely. If the fault happened excced 3 months, and not caused by improper operation, we will send repair parts to you freely, or you can return the projector to us for repairing, freight beared by both of us.Are projections also visible in daylight?Outdoors, projections remain invisible in direct sunlight or when the sky is overcast. The sun is a superior light source. Daylight outperforms any artificial light. With the sun shining through windows, the situation may be different: it must be tested whether the output of a projector is sufficient or not.How are projection templates manufactured?We manufacture gobos according to customers' digital artwork files. The files are manually controlled and set up to meet the requirements of a high-power laser and printing. The artwork is then engraved or printed with high precision in special coated glasses.

ICESUN can roof vacuum Windows with vacuum glass for Skylight. Vacuum glass for Skylights provide light and ventilation with high efficiency. The skylight can be used as the heat insulation layer of the house, and if choosing vacuum glazing for skylight, it will play a very good role in heat insulation. A house with tempered vacuum glass skylight can isolate more than 38 decibels of noise than a house without skylight, which can remove more noise from our life due to the soundproof vacuum glass. ICESUN vacuum glass has the obvious advantages: Sound insulation performance; Heat resistance; Thermal insulation; Sun proof function; Anti-condensation function; Low-e anti-radiation function; Long lifespan up to 50years; Wind resistance; Photochromic glass; Fireproof and bulletproof performance; Unique vacuum eye technology; Unique low temperature welding technology/

The introduction of cassava starch machine 1.It is a physical separation process which makes the starch separated from the cellulose, protein, inorganic salt and other material in fresh cassava tubers. 2.After crushing fresh cassava into mash materials, we add water in the mash and use a filter to remove the residue, and then we get starch milk with protein, a little tiny cellulose, and other impurities in it. 3.Because of starch is not soluble in cold water and has different specific gravity with water, specially designed machinery equipments can be used for separating starch from starch milk, and finally achieving the purpose of collecting starch. The capacity of cassava starch machine for the whole standard production line, the hot sales capacity include: 1.Output: 5 tons per hour tapioca starch machine 2.Output: 10 tons per hour tapioca starch machine 3. Output: 20 tons per hour tapioca starch machine 4.Output: 30 tons per hour tapioca starch machine 5.Output: 50 tons per hour tapioca starch machine 6.Output: 100 tons per hour tapioca starch machine note: 1.The capacity refers to ourput tapioca starch capacity 2.The machine will work continute for 24hours per day 3.We will also design the production line according to the customer's requirement.
