Description

The variable glory lighting device that conventional lamp and light-emitting diode (LED) module integrally combine

Technical field

The utility model relates to a kind of light-emitting diode (LED) lighting device, relates in particular to a kind of variable glory lighting device based on red, green, blue (RGB) primitive colours LED module that is combined as a whole with conventional lamp, also can be referred to as " frontlighting lamp ".

Background technology

Control Red Green Blue LED by special-purpose software, see through the different electric currents and the voltage that are applied on the LED electrode, can make Red Green Blue LED produce the light of different colours and different brightness separately.Though occurred this principle is used for the device of advertising lighting or light of stage in the market, but because conventional lamp, domestic electric fans etc. can't be with red as advertisement lighting lamp or stage lighting units, green, the primary colors led module is arranged remote the branch, if with red, green, the primary colors led module closely is provided with the damage that then can cause the RGB module because of the heating of bulb, therefore, also do not have and conventional lamp (bulb) so far, domestic electric fans etc. closely cooperate, and can produce the lighting device of the light of the different colours of good visual effect and different brightness.

The general introduction of utility model

Therefore, as mentioned above, how overcoming the influence to RGB primitive colours LED module of heat that conventional lamp, domestic electric fan etc. are produced, described RGB module and conventional lamp, domestic electric fan etc. are constituted an overall structure, is technical problem to be solved in the utility model.

The purpose of this utility model provides a kind of variable glory lighting device, this lighting device is based on the variable glory lighting device that the Red Green Blue led module combines with conventional lamp, make it both have original function, also owing to have the infinite visual effect of Red Green Blue change by led module and match and bring beautiful enjoyment to people.

Realize that the above-mentioned purpose technical scheme is: the variable glory lighting device that a kind of conventional lamp and light-emitting diode (LED) module integrally combine, comprise conventional lamp, wherein, described variable glory lighting device also has diffuser and the control box that joins together with conventional lamp, in described diffuser, be provided with the led module that is used to launch glory, in described control box, be provided with the control circuit that is used to control the led module running.

Described led module comprises the Red Green Blue LED group that is used for launching glory, links to each other with each LED of described LED group, be used to limit its electric current current-limiting resistance, be used to accept input control signal and become triode that circuit is connected and the printed circuit board (PCB) that is used to install these elements with corresponding described current-limiting resistance.

For the element packing density that improves led module adopts surface mounting structure, for this reason, the primitive colours LED in the led module adopts blockage shape tube core, and current-limiting resistance and triode adopt chip component.

For reaching the irreflexive effect of light, adopt translucent glass or plastics material as the diffuser housing.

Suitably choose the size and the placement location of diffuser according to concrete situation, make temperature in the diffuser housing than low 5-10 degree centigrade of the temperature around the housing, thereby the electronic component in the protection diffuser is avoided the influence of high temperature.

In described control circuit, also be provided with the IC that writes the control program of controlling LED sequence of light and brightness.

Lighting device of the present utility model, owing to will closely combine with conventional lamp based on red, green, blue (RGB) primitive colours LED module, make it both have original illumination functions, also bring beautiful enjoyment to people owing to have the fickle visual effect that produces by variable colored light device.

Embodiment

Variable glory lighting device of the present utility model can make red, green, blue (RGB) primitive colours LED module and conventional lamp, electric fan etc. be used.As an example, Fig. 1 shows the exploded perspective illustration of variable glory lighting device.In this figure, the 1st, bulb, the 2nd, diffuser overhead guard, the 3rd, LED group, the 4th, led module, the 5th, diffuser base, the 6th, lamp socket, the 7th, multicore cable, the 8th, control switch, the 9th, control box, the 10th, attaching plug.

Diffuser is an annular housing that is made of overhead guard 2 and base 5 these two parts.For the light that LED is sent has irreflexive effect, and can tolerate the heat that distributes when bulb is lighted, material should adopt milky glass or resistant to elevated temperatures plastics.Look size and installation site that the overall dimension that places the bulb on the diffuser axis and watt level are determined diffuser.Generally speaking,, then select the bigger diffuser of diameter for use, and make bulb far away slightly apart from the plane at diffuser place if the overall dimension of bulb or power are bigger, unlikely overheated with the electronic component in the protection diffuser.Generally, the temperature outer than housing of the temperature in the housing hanged down 5-10 degree centigrade.As an example, Fig. 2 A-Fig. 2 C has provided the diffuser of large, medium and small three kinds of patterns.

Led module 4 is placed in the diffuser.Led module 4 comprises annular printed circuit board (PCB) (PCB), is distributed in a plurality of LED groups 3 and other electronic components on the PCB.Each LED group 3 comprises Red Green Blue LED.Can adopt surface mounting technology (SMT) that these elements are installed on less PCB to high-density.For this reason, each LED group is made the pattern that comprises 3 blockages (dice) shape tube core, these three tube cores be respectively glow, the LED of green glow or blue light.Other electronic components comprise current-limiting resistance and three triodes that link to each other with each LED, and they also do slabbing, thereby are applicable to SMT.

Fig. 3 illustrates the circuit diagram of led module 4.Though there is shown 8 LED group LED1-LED8, the quantity of LED group is not limited to 8.Be connected to current-limiting resistance separately on the anode of each LED.For example, the LED that glows of LED1-LED8 is connected to resistance R 1-R8 respectively, or the like.Q1-Q3 is 3 triodes that are used to receive input control signal.Their base stage is connected to socket U4, grounded emitter, and the collector electrode of each triode links to each other with the anode of emission with a kind of 8 LED of color of light by 8 current-limiting resistances.The negative electrode of each LED connects 5 volts of power supplys.

Fig. 4 shows the circuit diagram of control box.It comprises power circuit, LED control signal output circuit and control circuit.Power circuit comprises transformer circuit, bridge rectifier, filter circuit and voltage stabilizing circuit.The LED output circuit comprises 3 triodes and is connected in resistance on separately the emitter.The other end of these resistance is connected to the corresponding base stage of 3 triodes of led module 4.An integrated circuit U1 is arranged in the control circuit, store the control program that is used to control LED sequence of light and brightness therein.

In controller, also has one 3 gear switch.When switch was pressed bulb one side, bulb was bright, and LED does not work.When switch was pressed the centre position, bulb and LED did not work.When switch by when LED one side, bulb does not work, and that transformer gets is electric, exports 6 volts of alternating voltages.Become 5 volts of DC power supply supplying with led circuit by bridge rectifier and filter circuit.By voltage stabilizing circuit, become 3 volts of DC power supply supplying with IC again.IC get electric after, by being stored in the specific program among the IC, the output specific signal promotes triode, lights the LED in the led module.Can will be programmed to according to a certain order (for example white-indigo plant-green-red-Huang) periodic duty, color gradient does not have jumping phenomena.

Being of wide application of variable glory lighting device of the present utility model.Be used for the light fixture except above-mentioned, it can also be used with electric fan etc.
