Ceiling lamp to buy Methods / procedures
Look at the radiator fixtures for use:Lamp radiating speed determines the LED attenuation and service life of the whole lamp. Lamp work under the condition of high temperature on long time, the light decay very fast, life is short, and the brightness of ceiling lamp is too poor, not to focus on the effect of illumination.Radiator scheme for LED ceiling lamp, the mainstream with integral type radiator way, one lamp with one radiating column mode, external fan cooling mode.In current user is more recognized way is single pearl beads a cooling column method. This approach will produce light emitting heat when quickly through the radiating column is emitted out each light bead, ensure timely cooling. While the overall type radiator is all the heat generated by the bulb is conducted to the aluminum substrate, and then through the radiator heat emitted, slower.The size of the radiator, aluminum quality will be affects the speed of heat dissipation, but also affect the whole lamp prices.The light power (commonly known as the transformer):
Transformer quality also determines the whole life of the lamp, lamp beads used more than 50000 hours no problem, if the transformer is attaint, and whole lamp is bright not up.Electronic component, transformer used in the design scheme determines the efficiency of transformer, power factor, stability, temperature rise, service life.Users can’t know the element device, from the transformer size, weight, and consult the manufacturers use electrolytic capacitors and other aspects the preliminary judgment. Differences in price of LED Ceiling lamp，quality of transformer no small proportion.Understand the brand and package beads:Bead quality decides LED ceiling lamp lighting effects, packaging technology, heat dissipation effect bulb quality key factors. Bead chip has Different brands, price is difference， The lighting effect is different too.Users can know beads scheme by consulting the manufacturer, integrity depends on the manufacturers. The low price of Ceiling lamp, making a lot of use of a defective product, color inconsistencies, brightness difference, short life, users need to pay attention to.
Ceiling lamp installation
Tools / raw material
Preparation of materials:
The LED light source 3 pcs
Circlip two piece
A lamp body shell
A piece of aluminum substrate
A terminal line
Lens 3 pcs
Solder paste spare
Screws 2 pcs
Iron reserve
Methods / procedures
First use the soldering iron to welded LED light source on the aluminum substrate
thermal paste put into back of aluminum plate and then put it inside the radiating shell;
Terminal line through the bottom of the shell，The soldering iron handle terminal lines are welded on the aluminum substrate negative pole respectively;
The lens is placed in the LED, and Fixed light source
Tightened cover and a lens;
The lamp body shell installed Are assembled together;
Then connected with the driving to be normal use
The matters needing attention
Connected with the electric voltage is 110V ，first electric closed then to install.
When the lamp Welding and aluminum plate can not be weak weld, terminal wire and the aluminum substrate can be weak weld too;
Unscrew the screws can not be screwed too tight;
The lamp can not fall.
