Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.

By shown in Figure 1, the utility model includes lamp holder, upper casing and lower casing, upper casing 1 is contained on the lamp holder 6, lower casing 2 is contained in upper casing 1 bottom, support 3 in being equipped with in the upper casing 1, the LED pipe 4 that stretches out hypovalve is housed on interior the support, and the LED pipe links to each other power supply two contacts on the input termination lamp holder of direct current rectification circuit with the output of the direct current rectification circuit on the circuit board 5.

Said LED pipe 4 is serially connected by lead for several LED Light-Emitting Diodes, all puts to be fixed on lower casing 2 surfaces, is generally 22 (only) (seeing shown in Figure 4); Lower casing 2 is hemispherical light face body, as frosted glass hemisphere face body; Interior support, lower casing and upper casing can be made (ABS) by fire proofing; Direct current rectification circuit on the said circuit board 5 is C type or R type, and said C type is that external power supply (civil power) two input lines are respectively through protective tube Fu, resistance R ₁And capacitor C ₁Connect by commutation diode D ₁-D ₄The input of the direct-current bridge of forming is equipped with overvoltage protection resistance R g, the output termination filter capacitor C of direct-current bridge between two power leads behind the protective tube Fu ₂With LED pipe (seeing shown in Figure 3); Said R type is that external power supply (civil power) two input lines are respectively through protective tube Fu, resistance R ₁, R ₂Connect by commutation diode D ₁-D ₄The input of the direct-current bridge of forming is equipped with overvoltage protection resistance R g between two power leads behind the protective tube Fu, the output termination filter capacitor C of direct-current bridge and LED pipe (seeing shown in Figure 5).

C type circuit and existing like product are basic identical, all are after adopting the capacitively coupled step-down, to carry out rectifying and wave-filtering again, resupply the acting of acting device.Here do not describing in detail.

R type circuit is that be used for specially dubing Optical controlled lamp and switch uses, because the circuit structure of sonic-opticalcon trolled switch is the conductive characteristic according to diode, it is given the just profound ripple of alternating current during near O and cuts off.It is long that the ac power waveform that the just profound ripple of normal alternating current is controlled through sonic-opticalcon trolled switch causes exchanging the ripple zero-crossing timing, if adopt C type circuit, it will produce stroboscopic and noise.Reason is after causing producing difference frequency, and people can feel that flashing is fixed, and the brightness under the low-light level state is too low, does not see surrounding environment, also can feel uncomfortable simultaneously.And use resistance step-down mode instead, though can increase some power attenuations, just in time can fill up the deficiency of C type circuit.In the workplace of the illuminating lamp that acousto-optic control is housed, continuous operation lamp when it belongs to has very reached no stroboscopic.And when the low-light level state, people also can see environment at one's side clearly.Because self circuit total value big (definitely doubly a lot of greater than 15W bulb resistance), promptly the consumption of the public affairs under low-light level state nature is also less than idle when state (black entirely) power consumption of 15W bulb.
