Description

A kind of LED indoor ceiling lamp

technical field

The utility model relates to the technical field of LED lighting, in particular to an LED indoor ceiling lamp.

Background technique

Light-emitting diodes are referred to as LEDs for short. Diodes made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc. Visible light can be radiated when electrons and holes recombine, so they can be used to make light-emitting diodes. It is used as an indicator light in circuits and instruments, or as a text or number display. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Due to chemical properties, it is divided into organic light-emitting diode OLED and inorganic light-emitting diode LED

Light-emitting diodes can also be divided into ordinary monochromatic light-emitting diodes, high-brightness light-emitting diodes, ultra-high-brightness light-emitting diodes, color-changing light-emitting diodes, flashing light-emitting diodes, voltage-controlled light-emitting diodes, infrared light-emitting diodes, and negative resistance light-emitting diodes. There are two kinds of LED control modes, constant current and constant voltage, and there are many dimming methods, such as analog dimming and PWM dimming. Most LEDs use constant current control, which can keep the LED current stable and not easily affected. The change of VF can prolong the service life of LED lamps.

Ceiling lamp is a kind of lighting and modern decorative lamp with noble grade, which is very suitable for shopping malls, supermarkets, hotels, jewelry counters and high-end homes. The main advantage of LED ceiling lights is low-carbon energy saving, adapting to the global trend of energy saving and emission reduction, and low-carbon life. It is an ideal choice for modern high-light homes. Under normal use, the lamp can reach 50000H, which is equivalent to the life of 50 incandescent lamps. Ceiling lamps, different from spotlights, mainly use scattered light sources, with a wide irradiation area, mostly soft light and uniform light spots. However, the existing ceiling lamps have low illumination brightness and poor heat dissipation performance, which affects the service life of the lamps. Therefore, in order to solve the above problems, a new technical solution is provided.
