Comparison of traditional downlights and LED downlights

1. Traditional downlight
Traditional down lamp is a large amount of indoor engineering lamps in engineering construction. It is widely used in shopping malls, special stores, special areas, office buildings and home decoration.
Traditional downlight is a kind of commercial lighting. As a kind of point light, it is usually distributed on the ceiling for space lighting.
Generally, the traditional down lamp can be equipped with incandescent bulb, which emits yellow light at this time. When installing the energy-saving lamp, it can emit white light or yellow light depending on the type of bulb.

2. Introduction to LED Downlight
LED downlight is a kind of lighting fixture that is embedded in the ceiling and emits light. It is a directional lighting fixture, and only its opposite side can receive light. The beam angle belongs to the spotlight type, and the light is more concentrated. The contrast between light and dark is strong, which makes the illuminated object more prominent. The lighting value is higher, and it sets off the quiet atmosphere.

The characteristics of LED downlight are as follows.
(1) Effect: keep the overall unity and perfection of architectural decoration, do not destroy the setting of lamps. The light source is hidden in the interior of architectural decoration, without glare, giving people soft and uniform visual effect.
(2) Energy saving: the power consumption of the same brightness is 1 / 4 of that of ordinary energy-saving lamps.
(3) Environmental protection: no mercury and other harmful substances, no pollution to the environment.
(4) Economy: the cost of lamps can be recovered in one and a half years due to the reduction of electricity consumption.
(5) Low carbon: saving electricity is equivalent to reducing carbon emissions.
The advantages of LED downlight are as follows.
(1) Energy saving: the energy consumption of white LED is only 1 / 8 of incandescent lamp and 1 / 2 of energy saving lamp.
(2) Long life: the theoretical life of LED can exceed 100000 hours.
(3) Can be frequent switch: if frequent start or turn off energy-saving lamp, filament will be black and quickly damaged.
(4) Solid state packaging: it belongs to the type of cold light source, so it is very convenient for transportation and installation.
(5) Cost performance: the luminous efficiency of lamps and lanterns is increasing, and the price is also decreasing.
(6) Environmental protection: it does not contain mercury and other substances harmful to the environment, and will not cause damage to the environment.
(7) Color rendering: it is closer to white light than the light emitted by traditional lamps. Under this light, the color of the object can be closer to its original color.
