Description

Color temperature and dimming lighting device

Technical Field

The utility model belongs to the technical field of lighting equipment, and particularly relates to a lighting device capable of adjusting color temperature and dimming.

Background

The lighting lamp is widely applied to various fields in life at present, the lamp provides great convenience for human life, and with the change of science and technology, various lamp styles are available in the market at present, and each lamp source has the characteristics of the lamp source. The LED lamp has unique photoelectric property, safety performance, environmental protection performance and respective cost performance no matter incandescent lamps, fluorescent lamps, metal halide lamps, electrodeless fluorescent lamps, mercury-free fluorescent lamps and LEDs for illumination. LEDs have great potential advantages in lighting applications, and as LED technology has become more sophisticated and cost has decreased, the applications and market share of LEDs have increased.

With the development of lighting technology, not only the light effect category is focused on in the evaluation of future lighting lamp sources, but also the evaluation of lighting effects, light comfort, light biological effects, light safety, environmental protection performance and resource consumption are emphasized. Furthermore, Light Emitting Diodes (LEDs) have advantages of low power consumption and long service life, so that they are gradually replacing the common incandescent light bulbs and power saving bulbs in the market, and the related products of the LED series are also gradually developing.

The conventional xenon lamp (high intensity discharge light) has a compatibility problem, because in addition to a self-ballasted mercury lamp, a bulb in the xenon lamp needs a ballast to work, wherein the ballast is divided into two types, one type is a controller configured by Constant Wattage Isolation (CWI), and the ballast needs to be matched with an igniter to generate a high-voltage arc to light the lamp; the other is a controller configured with a Constant Wattage Autotransformer (CWA), and the ballast output of the controller can light the lamps by connecting a capacitive coupling in series between the lamps without high voltage assistance for starting. However, a specific voltage is required in the xenon lamp to light the lamp, the xenon lamp cannot be directly connected to a mains supply, otherwise the lamp is damaged, and therefore the applicability of the LED is more flexible and the applicable range is wider.

On the other hand, the LED light source lamp system comprises a driving power supply and an LED light source, two modules with different functions are combined together, the driving power supply and the LED light source are heat sources generating high temperature, the high temperature is conducted after the driving power supply and the LED light source are combined together, so that the temperature of the LED light source lamp system is very high, the shell of the driving power supply is made of a PC material, the highest temperature is 120 ℃, and after the LED light source lamp works, the high temperature generated by the driving power supply is removed, and partial high temperature conducted by the LED light source is accumulated, so that the TC temperature point at the shell of the PC exceeds 120 ℃, so that the temperature of driving components exceeds the rated temperature, and the use effect is influenced; in addition, the LED light source part generates high temperature after working, and the temperature superposed by the radiation of the driving part causes the temperature of the LED lamp bead to be overhigh, thereby influencing the use effect. Aiming at the defects of the conventional lamp structure, how to effectively diffuse the heat generated by the electronic components and the driving power supply, and the heat of the electronic components and the driving power supply cannot influence each other, and the overall quality control, the durability of the lamp structure and the like are problems which need to be solved together.

The existing wired dimming products with the E-shaped screw cap LED light source lamp capable of dimming adopt a controllable gauge or other AC end adjusting schemes, so that the wired dimming products are not safe and cause low efficiency of the products, and only can be input by a single voltage (for example, the wired dimming products can only be connected to a 120VAC or 220VAC or 277VAC power grid).

At present, the E-shaped screw lamp cap LED light source lamp can only work in a single color temperature range (single light wavelength), can not meet the requirement of selecting multiple color temperatures of one lamp, and greatly increases the purchase SKU of a purchaser and the cost of logistics, storage, human resources and the like.
