Description

  The present invention relates to a lighting device having a color conversion device, and more particularly, to a lighting device having a color conversion device for adjusting the color temperature of two groups of LED bulbs.

  In general, a light emitting diode (hereinafter referred to as “LED”) basically includes a junction of a p-type semiconductor and an n-type semiconductor. When a voltage is applied, a band gap of the semiconductor is formed by a combination of electrons and holes. It is a kind of photoelectronic device that emits energy corresponding to (bandgap) in the form of light.

  Such LEDs include high-intensity light sources for flashes, liquid crystal display (LCD) backlights used in portable electronic devices (cell phones, camcorders, digital cameras, and PDAs), light sources for lightning boards, As the light source of illumination and switch illumination light source, indicator light and traffic signal light, its use range is increasing day by day, and it is in the spotlight as the next generation illumination that replaces the fluorescent light especially for power saving.

  A general white LED manufacturing method is manufactured by applying a yellow fluorescent material to a blue LED chip. However, the above-described method can be applied to LEDs having specific color temperatures (generally 3000K, 4000K, 5000K, 6000K). Is a method in which a large amount of fluorescent material is mechanically applied to a blue LED chip together with a sealing material.

  Conventionally, Patent Document 1 and Patent Document 2 have been proposed to manufacture LED lighting capable of adjusting color temperature. The conventional lighting device capable of adjusting the color temperature includes a wavelength adjustment, a current adjustment, and a voltage in order to achieve a desired color temperature using red (RED), green (GREEN), and blue (BLUE) LEDs. Since adjustment and brightness adjustment must be performed at once, there is an inconvenience that the color temperature cannot be adjusted accurately.

  In another method of adjusting the color temperature, in order to realize a desired color, a filling (sealing) material containing a fluorescent material is applied and separated through an electro-optical color temperature selection operation. A large number of LEDs are arranged on a printed circuit board (PCB), and a power supply unit is provided for driving via current control. Also, for heat dissipation and LED protection, the outer case is manufactured in an integrated type including a power supply unit, and then shipped after optical sorting.

  At this time, if a large number of LEDs having various kinds of hues and temperatures are arranged, a uniform light source cannot be obtained unless the light emission characteristics of the LEDs are always the same. Since only a part of the LEDs are used and the number of selected LEDs is limited, there is a limit to increasing the production amount, and there is a limit to reducing the production cost.

  In addition, according to the prior art, since it is necessary to manufacture an illumination array module by surface mounting only LED chips having selectively specific color temperatures, a separate process is required for each color temperature, and the illumination manufacturing process There was a problem that became complicated.

It is a conceptual diagram of the light source part used with the illuminating device which has the color converter which concerns on this invention.

  First, the concept of the present invention will be described.

  FIG. 1 is a block diagram of an illumination apparatus having a color conversion apparatus according to the present invention.

  In FIG. 1, reference numeral 100 denotes an illumination device having a color conversion device.

  As shown in FIG. 1, an illumination device 100 having a color conversion device is used as an indoor illumination device provided with existing piping wiring and provided with a switch such as a tumbler switch.

  A 100-v or 220-v AC power supply 120 is supplied, and a lighting device 100 having a color conversion device is connected via a switch 125.

  The lighting device 100 having such a color conversion device according to the present invention is turned on and off by an on / off operation of the switch 125. Therefore, the illuminating device 100 having the color conversion device according to the present invention can be used in place of an existing light bulb.

  And the illuminating device 100 which has a color converter is the light source part 180 (bulb) provided with one light source which consists of two groups, ie, the 1st light emission part 182, and the 2nd light emission part 184, as shown in FIG. including. In the embodiment of the present invention, the first light emitting unit 182 is a 3000K LED, and the second light emitting unit 184 is a 5,700K LED.

  As specifically described below, the first light emitting unit 182 and the second light emitting unit 184 of the light source 180 are lit separately.

  In these lighting operations, when the switch 125 is turned on, the first light emitting unit 182 that emits light of low color temperature is turned on. After the switch 125 is turned off, if the switch 125 is turned on within one minute, the light of high color temperature is emitted. The second light emitting unit 184 that emits light is turned on.

In this case, after the switch 125 is turned on, the second light emitting unit 184 of the 5,700K LED is turned on again within one minute after the switch 125 is turned off.

  Here, one minute can be used by setting a required time of several seconds to several tens of seconds or more depending on the actual situation of the site.

  Through such an operation, wasteful power consumption can be prevented by selecting and illuminating the color temperature of light.

  Examples of the present invention will be specifically described below.

  In FIG. 1, reference numeral 130 denotes a switching mode power supply device (SMPS: switching mode power supply, hereinafter referred to as “SMPS”). The SMPS 130 is a normal power supply device. In the present invention, a product with AC 100 to 220 v input and DC 38 v output is used.

  Reference numeral 140 denotes a constant voltage and timer circuit. As shown in FIG. 3, the constant voltage and timer circuit 140 supplies power to the flip-flop 145 for a certain time when the zener diode Z1 for maintaining the constant voltage and the DC 38v power supplied from the SMPS 130 are cut off. A capacitor C2 for supply is included.

  The output results based on the truth values of the SMPS 130 and the logic circuit 150 are as shown in Table 1 below.

  In Table 1, procedure 1 is a state in which the switch 125 is turned off. Since the switch 125 is off, no power is supplied to the lighting device 100 including the color conversion device.

  When the switch 125 is turned off in the procedure 4, the state of the procedure 1 is entered again.

  When the switch 125 is turned off in step 2 and a fixed time (1 minute) has elapsed, the state returned to the state of step 1 is maintained. Therefore, if the switch 125 is turned on again after the predetermined time has elapsed, the state of step 2 is obtained.
