A brief description of the drawings
The present invention will be more fully understood from the following detailed description and accompanying drawings of a preferred implementation of the present invention, which, however, should not be construed as limitations of the invention and which is used only for explanation and understanding it.
Figure 1 depicts a block diagram showing the electrical construction of a variant of implementation of the led lamp according to the present invention; and
figure 2 depicts a block diagram showing a basic point of management procedures that should be undertaken by a Central processing unit (CPU) 71 in the above implementation.
Description of the preferred embodiments
The present invention will be described in more detail below in its preferred implementation variant according to the attached drawings. In the present description, numerous specific details for a full understanding of the present invention. However, specialists in the art should be understood that the present invention can be implemented without these specific details. In this case, a well-known design, not shown in more detail in order to avoid excessive detail in the description of the present invention.
Figure 1 shows the block diagram showing the electrical construction of a variant of implementation of the led lamp according to the present invention. Block, connecting the power source AC is a plug 1 is equipped for connection to a source of AC power industrial type usually at 100 C. By inserting the plug 1 into the socket efficient power source through switch power supply 2 carry out the rectification of the alternating current and smoothing through the bridge diode rectifying circuit 3 and the condenser 4, and thus, the power source is converted into a source of DC power. To line source of DC power connected led group of red glow 5A, led the group 5b green glow and led the group 5C blue glow through the driver of the red glow 6A, the driver green glow 6b and the driver of a blue luminescence 6s. It should be noted that in the drawings, each color led group represented by one led. In fact, each color led group consists of a large number of LEDs. The LEDs in each color led groups are connected in series or in parallel. Also, three color led groups are mounted alternately for forming optical system so that the three colors of light mix well to radiation or scattering of the illuminating light.
Scheme 7 management also is driven from a source of DC power. Scheme 7 control contains a microcomputer that includes a CPU 71, a memory 72 random access, electrically programmable permanent memory (EEPROM) 73 (although it is not illustrated, it includes a diagram of the power supply to low voltage). The control circuit 7 serves as the integrating means, the counting means controls the mode of power supply and svitrigailos funds. The management process that should be followed by the CPU 71, illustrated in the block diagram presented in figure 2.
Driver 6A red glow driver 6b green glow driver and 6C blue glow is controlled by switching on and off the output signal to drivers individually through circuit 7 controls. In normal lighting circuit 7 controls continuously includes the appropriate drivers 6A, 6b and 6C to expose the maximum, respectively, led the group 5A of the red glow led group 5b green glow and led group 5C blue glow.
The shape of the signal from the source of alternating current supplied to the plug 1, is fed to the comparator 74 through a capacitor C and a resistor R for detecting the zero point of the alternating current signal. From the comparator 74, the output signal is a pulse signal synchronous with the signal from the source of AC power. For example, when the power source is an AC signal with a frequency of 50 Hz, the output pulse signal from the comparator 74 should have a frequency of 50 Hz to synchronize with the signal from the source of AC power. 16-bit counter 75 performs the expense of the pulse signal. A carrier signal of the counter 75 is calculated, the CPU 71 to record the calculated value in the memory 72 with random access.
The CPU 71 makes an increment of the integrated period of power supply, recorded in the EEPROM 73, by one unit each time the calculated value memory 72 random access reaches a value corresponding to one hour. While the calculated value memory 72 random access is lost when disconnecting switch of the power source 2, an integrated period of power supply, recorded in the EEPROM 73, will not fade or be lost. Thus, the reduced frequency of write access to the EEPROM 73.
When the switch 2 power source and, thus, activation of the CPU 71 during the initialization process checks integrated period of power supply, recorded in the EEPROM 73. If the integrated period of power supply has not yet reached 50000 hours, drivers 6A, 6b and 6C of the respective colors are kept continuously enabled to supply power to the led groups 5A, 5b and 5C of the respective colors glow in normal lighting.
If the integrated period of power supply is within 50000-60000 hours, drivers 6A, 6b and 6C are run mode of the first notice for five minutes. In the first mode prior notice led group of red glow 5A and led a group of green fluorescence 5b glow continuously, and led the group blue glow 5s glows intermittently, twinkling. After five minutes of operation, the first preliminary information mode drivers 6A, 6b and 6C is switched to the normal lighting for a continuous glow all led groups 5A red glow, 5b green fluorescence and 5C blue glow.
If the integrated period of power supply is within 60000-70000 hours, drivers 6A, 6b and 6C are run mode of the second notice for five minutes. In the second mode prior notice led group 5b green glow and led the group 5C blue glow glow continuously, and led the group 5A of the red glow illuminates intermittently, twinkling. After five minutes of operation, the second pre-drivers messages 6A, 6b and 6C their mode of operation is switched to the normal lighting for a continuous glow all led groups 5A red glow, 5b green fluorescence and 5C blue glow.
If the integrated period of supply-the power supply is within 70000-80000 hours, drivers 6A, 6b and 6C are run in the third notice for five minutes. In the third prior notice led group 5A red lighting and led the group 5C blue glow glow continuously, and led the group 5b green glow shines intermittently, twinkling. After five minutes of operation, the third preliminary message mode drivers 6A, 6b and 6C is switched to the normal lighting for a continuous glow all led groups 5A red glow, 5b green fluorescence and 5C blue glow.
If the integrated period of power supply is within 80000-90000 hours, drivers 6A, 6b and 6C are run mode double notice for five minutes. In the fourth mode notice all led group 5A red glow, 5b green fluorescence and 5C blue glow glow intermittently, twinkling all together. After five minutes of operation, the fourth preliminary message mode drivers 6A, 6b and 6C is switched to the normal lighting for a continuous glow all led groups 5A red glow, 5b green fluorescence and 5C blue glow.
If the integrated period of power supply is within 90000-100000 hours, drivers 6A, 6b and 6C are run for five minutes in the fifth mode prior notice. In the fifth mode prior notice led group 5b green glow and led the group 5C blue glow held off so that they did not glow, and led the group 5A of the red glow illuminates intermittently, twinkling. After five minutes of operation, the fifth notice mode drivers 6A, 6b and 6C is switched to the normal lighting for a continuous glow all led groups 5A red glow, 5b green fluorescence and 5C blue glow.
If the integrated period of power supply exceeds 100000 hours, supported by the fifth preview the message in which the led group 5b green glow and led the group 5C blue glow held off in order not to glow, and led the group 5A of the red glow illuminates intermittently, twinkling, without logging in normal lighting.
During the operation mode checks the integrated period of power supply, recorded in the EEPROM 73, every hour, during which the updated integrated period of power supply, recorded in the EEPROM 73, to perform the required appropriate operation mode according to the preliminary message.
As described above, the led lamp according to the present invention can integrate the period of power supply by measuring the period of power supply for led groups based on the frequency of the alternating current power source and to light the led groups in the selected mode prior notice, when the integrated period of power supply higher than the corresponding value of the notice to notify the user or Manager, located near the lamp, that is approaching the end of life led bulbs. When given a preliminary report, the Manager or the user can prepare a replacement. Especially, it would be convenient to provide multiple modes of preliminary message service life depending on the degree of fatigue of the lamp.
