The utility model discloses a dimmable LED (light emitting diode) lamp. The LED lamp comprises an LED driver, an LED lamp panel and a switch controller; the LED lamp panel is formed by connecting multiple LEDs in series; a controllable switch is arranged between any two LEDs; the LED driver is connected with two ends of an LED serial connection circuit; the switch controller is configured to control the controllable switches. The regulation on the brightness of the LED lamp is realized by the controllable switches in the LED lamp panel, and the switch controller adopts the modularized design, so the circuit structure of the LED lamp is simple, the integral cost is reduced, and a part of LEDs are in the non-work state during dimming, so the service life of the LED lamp is prolonged.
Description
Technical field
The utility model relates to LED lighting field, relates in particular to a kind of LED lamp of tunable optical.
Background technology
The LED illumination that is called as third generation illumination is in the develop rapidly stage, day by day increases at the proportion of lighting field.LED illumination is compared with traditional lighting, more easily realizes the control to light, the dimming function that the large daily life of a family is said.
As everyone knows, in order to make LED lamp luminous more stable, service life is more reliable, and the driver of most LED lamps adopts constant current output driver, so most light-adjustable LED lamp is all to realize the bright dark control of light by the output current size of change driver.
But the output current that changes driver has following shortcoming: first, have the LED driver circuit more complicated of regulation output size of current function, the cost of driver is higher, and complicated circuit reduces the reliability of driver; Secondly, in the time of regulation output size of current, LED is the state in lighting all the time, is unfavorable for the situation that LED lamp works long hours.
Utility model content
The purpose of this utility model is to provide a kind of LED lamp of tunable optical, to ensure that the brightness that realizes LED lamp is adjustable in the situation that reducing LED lamp holistic cost and simplifying complexity in circuits, extends the service life of LED lamp.
For achieving the above object, the utility model proposes a kind of LED lamp of tunable optical, described LED lamp comprises LED driver, LED lamp plate and on-off controller, wherein said LED lamp plate is in series by multiple LED, between any two LED, gate-controlled switch is set, described LED driver is connected in LED series circuit two ends, and described on-off controller is configured to control described gate-controlled switch.
Preferably, the multiple LED in described LED lamp plate are divided into some groups, between first LED of every group and last LED, gate-controlled switch are set.
Preferably, described on-off controller adopts modularized design.
The beneficial effects of the utility model are to realize the brightness regulation to LED lamp by gate-controlled switch is set in LED lamp plate, and on-off controller adopts modular design, make the circuit structure of LED lamp simple, reduce overall cost, in the time of light modulation, part LED, in off position, has therefore extended the service life of LED lamp.
Brief description of the drawings
Fig. 1 shows the composition frame chart of the related LED lamp of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1, the LED lamp related according to the utility model comprises LED driver 10, LED lamp plate 20 and on-off controller 30.The LED constant-flow driver that wherein said LED driver 10 is standard, for described LED lamp plate 20 provides constant electric current; Described LED lamp plate 20 is in series by multiple LED, in order more easily to realize the brightness regulation to LED lamp, realize dimming function, the numerous LED on LED lamp plate 20 are divided into some groups by the utility model, and be provided with gate-controlled switch between first LED in every group and last LED; Described on-off controller 30 adopts modularized design, sends control signal for the some gate-controlled switches to LED lamp plate 20, to realize the dimming function of LED lamp.
Concrete describe as example the numerous LED on LED lamp plate 20 are divided into four groups.Between first LED of first group of LED201 and last LED, be provided with the first controllable switch S 1; Between first LED of second group of LED202 and last LED, be provided with the second controllable switch S 2; Between first LED of the 3rd group of LED203 and last LED, be provided with the 3rd controllable switch S 3; Between first LED of the 4th group of LED204 and last LED, be provided with the 4th controllable switch S 4.
LED driver 10 is connected to the two ends of the series circuit in LED lamp plate 20, and on-off controller 30 is formed associated with each gate-controlled switch in LED lamp plate 20.
In concrete implementation procedure, LED lamp is lighted normal work, in the time that needs regulate its brightness, controls gate-controlled switch as required carry out conducting or turn-off relevant LED by on-off controller 30.Suppose as required, the first controllable switch S 1 controlled by on-off controller 30 and the 3rd controllable switch S 3 is closed, and has therefore caused first group of LED201 in LED lamp plate 20 and the 3rd group of LED203 by short circuit, does not work; The second group of LED202 of constant current driven and the 4th group of LED204 that export from LED driver 10 are normally luminous, finally by the variation of luminous LED quantity, have realized the brightness regulation of LED lamp, have realized dimming function.
The related LED lamp of the utility model is realized the brightness regulation to LED lamp by gate-controlled switch is set in LED lamp plate 20, and on-off controller adopts modular design, make the circuit structure of LED lamp simple, reduce overall cost, in the time of light modulation, part LED, in off position, has therefore extended the service life of LED lamp.
