Abstract

The utility model discloses a light emitting diode (LED) lamp capable of adjusting a light energy effect. The LED lamp comprises LED chips, a substrate for bearing the LED chips, and power supplies for driving the LED chips. The LED lamp is characterized in that three-primary color chips packaged by adopting a chip-on-board integration technology are arranged on the substrate, wherein the three-primary color (red, green and blue) chips are packaged on the substrate in a ratio of 3:6:1; and the LED chips with three different colors are independently driven by different power supplies. The independent power supplies drive the different LED chips to emit light, so that the light energy effect display can be adjusted; and a built-in wireless control module receives wireless signals to adjust the light energy effect, so that the ratio of blue rays can be raised, and the aim of promoting photosynthesis can be fulfilled.

Description

Can regulate the LED lamp of luminous energy effect

Technical field

The utility model relates to the LED lamp, relates in particular to the LED lamp that a kind of luminous energy effect can be adjusted.

Background technology

In the LED lamp, adopt trichromatic LED electroluminescent lamp pearl; can allow lamp present nature white illumination effect after the color matching; some studies show that; the color of illumination is more near available light; protection effect for eyesight is better; and the comprehensive integral performance, resolving effect and the definition general performance of looking thing under the LED light near available light are better, so a lot of LED lamp is all attempted color matching chip and luminous energy effect are optimized design and configuration.

But in the prior art, the LED light that configures can effect just be determined, and can not adjust the luminous energy effect again, perhaps makes change for the varying environment demand.Such as now along with the integrated aggravation of office and the raising of building density, less and lessly office in can collect sunshine, so, even outdoor unusually bright, the indoor white-light illuminating that still needs.Simultaneously, because the abominable and outdoor noise of air quality, people still less can select to window to reach the purpose that purifies air.In order to improve air quality, increase indoor oxygen content, people have to by means of the photosynthesis of indoor green plants.But can't effectively collect the bottleneck that sunshine has also become the restriction photosynthesis of plant.Because the light of blue light wavelength can effectively promote photosynthetic generation, promotes photosynthesis so there is the people to take to arrange blue light source, effect is all right, but has but increased cost and power consumption.Therefore, a kind of hardware facility that additionally do not increase but can be taken into account illumination and promote that photosynthetic intelligent lighting product just seems necessary.In addition, in order to satisfy some other specific functions, as utilize disinfection by ultraviolet light, be increased in the resolving effect of the font of printing on the color paper of having powerful connections etc., can consider that all changing the luminous energy effect realizes.

Summary of the invention

The utility model has proposed the LED lamp that do not need additionally to increase hardware facility, can in use regulate the luminous energy display effect especially for above problem.

The technical solution of the utility model is: a kind of LED lamp of regulating the luminous energy effect, comprise led chip, the substrate of carrying led chip, the power supply of driving LED chip, it is characterized in that, be provided with the three primary colors chip that adopts the encapsulation of chip on board integrated technology at substrate, wherein three primary colors red, green, blue chip is encapsulated on the substrate with the ratio of 3:6:1, and three kinds of LED modules with different colors chips are subject to independently respectively different electrical power and drive.

In described power supply region, be provided with wireless control module, control power initiation power output.

Be provided with control led chip luminous pulse width modulation microprocessor at described power supply, utilize PWM(Pulse Width Modulation) carry out pulse width modulation.

Carry out the ratio of wireless adjusting blue light, the intensity of white light, the color of light by wireless control module, can regulate by the mode of PWM modulation.

The beneficial effects of the utility model: independent current source drives the different LED chip light emitting, can regulate the luminous energy effect shows, receive wireless signal by the interior wireless control module of establishing the luminous energy effect is regulated, can allow the ratio of blue ray raise, can reach the photosynthetic purpose of promotion.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.

A kind of LED lamp of regulating the luminous energy effect, comprise led chip 1, the substrate 2 of carrying led chip 1, the power supply of driving LED chip 1, it is characterized in that, be provided with the three primary colors chip that adopts the encapsulation of chip on board integrated technology at substrate 2, wherein three primary colors red, green, blue chip is encapsulated on the substrate 2 with the ratio of 3:6:1, three kinds of LED modules with different colors chips 1 are subject to independently respectively different electrical power and drive, and have shown the red-light LED 1.1, green light LED 1.2, the blue-ray LED 1.3 that are integrated on the substrate in Fig. 1.

Shown in Figure 3 in its waveform such as the accompanying drawing.The RGB waveform is three kinds of different colours waveforms, is the waveform that single-chip microcomputer among the figure two outputs to the mos gate utmost point.Wherein the cycle of three kinds of signals of RGB is T, the high level time of ruddiness (R) is T1, the high level time of green glow (G) is T2, the high level time of blue light (B) is T3, then the white light cycle after the color matching is T, high level time Ton=T1+T2+T3, and dutycycle is Ton/T, by the adjusting to T1T2 and T3, then can reach light modulation and toning purpose.Wireless control module among the figure two can adopt infrared or other remote control modes.

What Fig. 1 showed is chip on board integrated technology (COB technology) encapsulation signal, the led chip that different fillings the represents different wave length wherein general proportions of red, green, blue is 3:6:1, the led chip that can send different wavelengths of light adopts the COB technology to be encapsulated according to certain rule, then when all lamps during all by current drives, whole COB lamp can send the purposes that balanced white light satisfies illumination.The diagram pattern does not represent real led chip quantity and position only for signal.

What Fig. 2 showed is the whole system theory diagram.By rectifier and jamproof electromagnetic interface filter and the control that drives chip, can produce three tunnel constant currents and drive signal and drive respectively three-color LED chip among the COB.Single-chip microcomputer can produce pwm signal, thereby and controls the purpose that trichromatic ratio is realized light modulation and toning by pwm signal.Clock in the single-chip microcomputer can be implemented in certain automatic control constantly and makes the ratio rising of blue light reach the photosynthetic purpose of promotion.Also can pass through wireless remote control, realize various light modulation toning functions.By the perception to existing intensity of illumination, single-chip microcomputer can arrange different mode of operations, realizes energy-conservation purpose thereby reached the reduction power consumption.
