Put optical lens, LED popularity rates could be improved, due to the energy saving that LED illumination is protruded, as the Main way that illumination develops,
But low side small-power plastic housing illumination is not enough, high-end high-power aluminum hull illumination radiating is all good but cost of manufacture is higher, should low cost
The taller ovenable supply of effect small size of good heat radiating again, the development to LED proposes requirement very high.
The content of the invention
Glass bulb not only insulate but also dust-proof fire prevention, and easily into lens and slight drop resistant, good heat dissipation can the no frangible glass of hand touch
Glass, assembling parts it is quick detachable it is recyclable it is secondary utilize, but glass bulb can not use screw connection, so in design use stress
The methods such as surface cover clinching are arranged in pairs or groups, and also to avoid glass from being blown with regard to pattern, and mechanical structure through hole is difficult the requirement such as die casting, uses
A kind of bottom of screw socket bottle lamp bucket extends out convex lens, and screw socket body both sides indent goes out two methods of wire lead slot, then in bottle bucket set
Upper plastic cement hemisphere lid, by lamp head fastening, lamp bucket belly shirt wiring board, plastic cement hemisphere belly shirt LED lights core,
Wiring board goes out lead to groove and plugs into LED from bottleneck, and LED substrate connects outer layer radiating, and line dome contacts of starting to exchange fire open draw-in groove and are equipped with quick-drying
Glue encapsulates stress, and lamp holder capping is non-rotary piston, tightens screw socket skin in upper lid recessed pressure clamping molding assembly.Because glass bulb is received
Mounting condition is limited, and volume receives weight, and lamp body can not be excessive, it requires that wiring board is small.By optocoupler self-locking with releasing certainly
The unidirectional pulse oscillating circuit of lock, optocoupler reception pipe is directly power output, can do full paster circuit, unidirectional pulse do it is non-every
It is lower from power-efficient security higher, the reception pipe of optocoupler is such as newly done for high-power optical transistor, add several resistance
Electric capacity can be integrated into unidirectional oscillating tube.Two-way recommending output mode oscillating circuit is then that two reception pipes of optocoupler connect transmitting tubes simultaneously
Connection, any only one of which optocoupler turns on self-locking to control in turn conductings and cut-off of the NMOS with two triodes of PMOS to pipe, defeated
Go out by the positive and negative push pull mode of capacitance current-limiting, the full paster of integrated circuit, can do insulating power supply, capacitance current-limiting can improve triode
Service life, improve lamp body quality.Two-way recommending output mode has discrete component to export conditioned circuit, discrete component varying duty
Feedback equalization circuit, and the big integrated push-pull oscillator pipe circuit of output of optocoupler is newly done, adapt to various insulating power supplies designs.
