Description

Light-emitting devices and lamps

This creation relates to a light-emitting device and a lamp, in particular to a light-emitting device that controls the correlated color temperature of the light-emitting diode through the arrangement of the diodes, and a lamp made of the light-emitting device.

According to press, in recent years, due to the rapid development of light-emitting diode (Light-Emitting Diode, LED) related technology, its light-emitting technology has been widely used in lighting and backlighting and other fields, and because the life of LED is longer than that of incandescent bulbs, It also consumes much less power than incandescent bulbs. Furthermore, LEDs also have the advantages of being light, thin, short, and good color saturation, and have become the most developed light source.

Taking the white light generated by LED as an example, white light is a combination of multiple types of light with different wavelengths, and one way to characterize white light is to use color temperature. The so-called color temperature refers to the color temperature of black body metal radiation. In other words, color temperature is the spectral components contained in various light sources. The specific method is: use a standard black body metal, such as iron or tungsten, to continuously heat the standard black body metal. During the heating process, different temperatures will emit light. Light of different colors, when the temperature gradually increases, the color of the light will continue to change. This color light that changes with temperature is the spectral component of standard blackbody radiation, and the spectral component also changes with temperature, so the color temperature is the radiation light. color temperature. In simple terms, color temperature means the color of light in white light, and Correlated Color Temperature (CCT) refers to the specification of the color appearance of light emitted by a light-emitting device. The CCT rating of a light-emitting device usually refers to the warmth or Cool, CCT rating is basically a measure of the color of light emitted by a lighting fixture as cool white or warm white, when a lighting fixture with a CCT rating below 3200K is considered a warm light source, or called warm white (yellow-white to red), And light-emitting devices above 4000K are identified as cold light sources, or cool white (blue-white).

As light-emitting diodes are used more and more widely, including residential, commercial buildings, hospitals or educational institutions, etc., it is expected that LEDs can have various CCT ratings, and LEDs can be expected to emit different hues. Therefore, with Luminaires with LEDs whose CCT ratings can be easily changed are most advantageous. In order to achieve the above purpose, the "Manually controllable LED correlated color temperature light fixture" of US Patent No. US10091855B2 (Document 1) was developed to solve the above problem. Different CCTs, combined with the CCT switch components and resistors in the circuit, manually switch the circuit to select a specific LED light source or LED combination, so that the lamps exhibit different CCTs.

In the circuit of Document 1, a resistor is used to mix the light emission of two different CCT LEDs into a mixed CCT. However, the resistor usually has an error value of ±1%~±5%, which makes the voltage unstable during the power-on process. As a result, the luminous efficacy of the LED will be unstable, so the aforementioned hybrid CCT will also be unstable. In addition, since the CCT switch assembly of Document 1 needs to be toggled by hand, the size of the hand must be considered, so it cannot be miniaturized, which is not conducive to the progress of product miniaturization. Therefore, how to effectively avoid the problems such as the voltage and current instability of the light-emitting device that are easily caused by the use of switching devices or resistor structures to adjust the color temperature of the traditional light-emitting device through innovative hardware design is a problem for developers and related industries such as light-emitting devices. Researchers need to continue to work hard to overcome and solve the problem.

The main purpose of the present invention is to provide a light-emitting device, which has stable voltage when the hybrid CCT is achieved, and can be miniaturized. This creation uses diodes to control the hybrid CCT of the light-emitting device, effectively replacing the resistance of the traditional light-emitting device with the diode, so as to stabilize the voltage of the light-emitting device and then the hybrid CCT, thus overcoming the instability of the hybrid CCT of the traditional light-emitting device. question.

In other embodiments, each of the first light-emitting body (111) and a second light-emitting body (112) is a light-emitting diode group formed by a plurality of LEDs connected in series, and does not include a resistor therein. The light-emitting device (1) of a preferred embodiment of the present invention can combine the light emitted by the first light-emitting body (111) with a CCT of 5000K and the light emitted by the second light-emitting body (112) with a CCT of 3000K, Light that is mixed into a mixed CCT, eg, the mixed CCT is 4000K.

The control circuit (12) disposed on the other end face of the circuit board (14) relative to the first luminous body (111) and the second luminous body (112) is composed of at least a distributor (121), a jumper The connector (122), a first voltage stabilization module (123) and a second voltage stabilization module (124) are combined, wherein the distributor (121) includes a plurality of distribution groups (1211), For example, three such distribution groups (1211). Each of the power distribution groups (1211) includes two independently arranged (non-electrically connected) electrodes (also called PIN pins) (12111), and the jumper (122) is provided with a connecting wire (1222) and The terminals (1221) at both ends of the connecting line (1222) are respectively, when the jumper (122) is sleeved on one of the power distribution groups (1211), the two terminals (1221) are respectively corresponding to the power distribution unit (1211). The two electrodes (12111) of the power distribution group (1211) are in contact with each other. Since the two terminals (1221) are electrically connected to each other through the connecting wire (1222), the two electrodes (12111) will also be connected to each other. Being electrically connected to each other, when the power distribution group (1211) is energized, the first light-emitting body (111) and/or the second light-emitting body (112) can emit light.

Please refer to FIG. 5, when the jumper (122) is clamped with tweezers and the jumper (122) is set at a first position (R1), the three power distribution groups (1211) are located at the top The power distribution group (1211) (also referred to as the first power distribution group) is electrically connected with the power supply (13) by the jumper (122), because the power distribution group (1211) located at the top is directly The first light-emitting body (111) is electrically connected, so that the electrical energy provided by the power supply (13) can be directly transmitted to the first light-emitting body (111) through the power distribution group (1211), so that the first light-emitting body (111) can be The light-emitting body (111) emits light with a CCT of 5000K and a first original luminous flux. Similarly, when the jumper (122) is set at a third position (R3), the power distribution group (1211) located at the bottom among the three power distribution groups (1211) (also referred to as the third power distribution group) ) is electrically connected to the power supply (13) by the jumper (122), since the power distribution group (1211) located at the bottom is directly electrically connected to the second light-emitting body (112), therefore, the power The electrical energy provided by the supplier (13) can be directly transmitted to the second luminous body (112) through the power distribution group (1211) located at the bottom, so that the second luminous body (112) can emit a CCT of 3000K and has a The second original luminous flux of light. The aforementioned first original luminous flux refers to the luminous flux of light emitted by the first illuminant (111) at a specific voltage, and the second original luminous flux refers to the second illuminant (112) at the specific voltage. The luminous flux of light. When the jumper (122) is set at the first position (R1) and the third position (R3) respectively, the first luminous body (111) and the second luminous body (112) receive the The specific voltage can be regarded as a supply voltage provided by the power supply (13). The two specific currents flowing through the first light-emitting body (111) and the second light-emitting body (112) are respectively related to the number of LEDs respectively possessed by the first light-emitting body (111) and the second light-emitting body (112) , the first light-emitting body (111) and/or the second light-emitting body (112) is a single LED or a light-emitting diode group formed by a plurality of LEDs connected in series, and does not include a resistor therein. Since the supply voltage has been determined, two specific currents of the first light-emitting body (111) and the second light-emitting body (112) are determined, that is, when the supply voltage is stable, the first light-emitting body (111) ) and the two luminous fluxes of the second light-emitting body (112) are also stable.

It is particularly noted that, in another embodiment (the variation of the embodiment in FIG. 5 ), the inlet end of the second voltage stabilization module (124) is electrically connected to the third power distribution group (three of the power distribution groups). The lowermost distribution group (1211) in the group (1211)), instead of electrically connecting the second distribution group (the middle distribution group (1211) of the three distribution groups (1211)), the third distribution group (1211) The output terminals of the two voltage regulator modules (124) are electrically connected to the second light-emitting body (112). When the jumper (122) is set at the third position (R3), the power distribution group (1211) (also referred to as the third power distribution group) located at the bottom of the three power distribution groups (1211) is connected by The jumper (122) is electrically connected to the power supply (13), and the electrical energy provided by the power supply (13) can also be transmitted to the power inlet of the second voltage regulator module (124), Then, it is transmitted to the second light-emitting body (112) from the outlet end of the second voltage stabilization module (124). Since the supply voltage is stepped down by the second voltage stabilization module (124), compared to the case where no current flows through the second voltage stabilization module (124), the second voltage stabilization module (124) and the second illuminator pass through the second voltage stabilization module (124). The current of (112) will be relatively small, and at this time, the second light-emitting body (112) can emit light with a CCT of 3000K and less than the second original luminous flux.

Continuing to return to FIG. 5, one end of the first voltage stabilization module (123) is electrically connected to the first light-emitting body (111), and the other end is electrically connected to the three power distribution groups (1211). The power distribution group (1211) (also referred to as the second power distribution group) and the second voltage stabilization module (124) located in the middle. The first voltage stabilizing module (123) is formed by a diode group, the electricity outlet of the diode is electrically connected to the first light-emitting body (111), and the electricity input end of the diode The system is electrically connected to the power distribution group (1211) located in the middle and the second voltage stabilization module (124). In particular, the definition of the aforementioned diode system is different from that of LED. The diode referred to in this creation is an electronic component with two electrodes with asymmetric conductance, which cannot emit light and has a rectifying or voltage rectifying function, so it is different from LED ( LEDs) are not the same.

One end of the second voltage stabilization module (124) is electrically connected to the distribution group (1211) located in the middle and the first voltage stabilization module (123), and the other end is electrically connected to the second light-emitting device body (112). The second voltage stabilizing module (124) is formed by another diode group, the other diode group is formed by two diodes connected in series, and the output terminals of the series connected diodes are electrically connected to each other. The second light-emitting body (112) is electrically connected, and the input terminal of the series-connected diode is electrically connected to the power distribution group (1211) and the first voltage-stabilizing module (123) located in the middle. It is particularly noted that, in other words, the first voltage regulator module (123) and/or the second voltage regulator module (124) may be a diode or a plurality of diodes connected in series.

When the jumper (122) is set at a second position (R2), the power distribution group (1211) located in the middle of the three power distribution groups (1211) is supplied by the jumper (122) and the power supply The device (13) is electrically turned on, and a supply voltage (that is, the specific voltage mentioned above) transmitted from the power supply (13) will be connected to the input terminal of the first voltage regulator module (123). The power-in terminal of the second voltage stabilization module (124) and the second power distribution group are electrically connected to a junction point (P) of the intersection. Corresponding to the supply voltage, a supply current begins to be shunted at the junction (P), and after a shunt passes through the diode of the first voltage regulator module (123), there is a voltage drop across the diode, which passes through the voltage drop. The reduced voltage is transmitted to the first luminous body (111) and the shunt through the first luminous body (111) is smaller than the current when the diode of the first voltage regulator module (123) is not passed, so that the The first illuminant (111) emits light with a CCT of 5000K and less than the first original luminous flux. That is to say, the voltage drop is generated between the junction point (P) and the outlet end of the first voltage regulator module (123). For example, when the voltage drop is about 5% of the supply voltage, at this time, the luminous flux drops sharply by about half of that without the voltage drop, which is called the first luminous flux, and the first luminous flux is smaller than the first original luminous flux. After another shunt passes through the second voltage stabilization module (124), there is also a voltage drop, and the voltage after the voltage drop is transmitted to the second luminous body (112) and passes through the second luminous body (112). The other shunt is smaller than the current when the diode of the second voltage stabilization module (124) is not passed, so that the second illuminator (112) emits light with a CCT of 3000K and less than the second original luminous flux. That is to say, the voltage drop is generated between the junction point (P) and the outlet end of the second voltage regulator module (124). For example, when the voltage drop is about 5% of the supply voltage, the luminous flux has a steep drop of about half of that without the voltage drop, which is called the second luminous flux, and the second luminous flux is smaller than the second original luminous flux. Therefore, the first luminous flux and the second luminous flux are mixed into light with a CCT of 4000K (the total luminous flux of the aforementioned first luminous flux and the aforementioned second luminous flux).

Of course, in the present invention, the third power distribution group may not be provided, and similarly, the light-emitting device (1) with a mixed CCT of 4000K light can be achieved.

In particular, the present invention replaces the resistance of the traditional light-emitting device with a diode to stabilize the voltage of the light-emitting device (even if the current passing through the light-emitting body is stable) and then stabilize the hybrid CCT, thus overcoming the instability of the hybrid CCT of the traditional light-emitting device. The problem. At the same time, the miniaturization of the light-emitting device is achieved by only using a jumper in the form of a PIN pin.

In particular, the first light-emitting body (111) and the second light-emitting body (112) in the present invention may also emit light of different wavelengths respectively.

Referring to FIG. 6, in a particular embodiment, the light-emitting device (1) may have only one light-emitting body, for example, the light-emitting device (1) at least includes: the first light-emitting body (111); and the light-emitting body (111); The control circuit (12) includes the distributor (121) and the first voltage stabilization module (123); wherein, the distributor (121) includes at least two distribution groups (1211), each of which is The power distribution group (1211) includes two independently arranged electrodes (12111); the at least two power distribution groups (1211) are respectively the first power distribution group and the second power distribution group, and the first voltage stabilization module One end of (123) (eg, the outgoing terminal of the diode) is electrically connected to the first light-emitting body (111), and the other end (eg, the incoming terminal of the diode) is electrically connected to the first light-emitting body (111). The second power distribution group; and, the first voltage stabilization module (123) is provided with at least one diode. The embodiment of FIG. 6 can be used to select or adjust the luminous flux emitted by the first light-emitting body (111). For example, when the jumper (122) is clamped with tweezers and the jumper (122) is set at the first position (R1), the power distribution group located at the top of the two power distribution groups (1211) (1211) (also referred to as the first power distribution group) is electrically connected to the power supply (13) by the jumper (122), since the power distribution group (1211) located at the top (this time is The first power distribution group) is directly electrically connected to the first light-emitting body (111), therefore, the electrical energy (the supply voltage) provided by the power supply (13) can be directly transmitted to the first power distribution group (1211) through the power distribution group (1211). The light-emitting body (111) can make the first light-emitting body (111) emit light, which is called the first original luminous flux. When the jumper (122) is set at the second position (R2), the power distribution group (1211) located below (the second power distribution group at this time) is supplied by the jumper (122) and the power supply The device (13) is electrically turned on, and after the supply voltage transmitted from the power supply (13) passes through the diode of the first voltage regulator module (123), there is a voltage drop across the diode, The voltage after the voltage drop is transferred to the first light-emitting body (111), for example, the voltage drop is about 5% of the supply voltage.
