The specific embodiment
The utility model proposes a kind of LED lamp device with safeguard structure, and its light structures adopts the reflecting type illumination, comprises lamp stand, LED light fixture and reflector, and the LED light fixture is located at the reflector below, and it also comprises: lift and quadrangle crane; The quadrangle crane comprises upper end turning joint, lower end turning joint and two intermediate active joints between them; Lift is fixed on the lamp stand, and it is connected with the lower end turning joint of quadrangle crane through elevating lever; The last turning joint of quadrangle crane is fixed on the lamp stand, and the LED light fixture is fixed on the intermediate active joint; On lamp stand, be provided with chute, lower end turning joint is connected with chute through slide mass, and it is up and down in chute that elevating lever drives slide mass; On reflector, be provided with the crown top of burner of ccontaining LED light fixture, when the LED light fixture rose to a high position, the LED light fixture was in the crown top of burner chamber of the crown top of burner.Tetragonal four summits all can be rotated, and promptly four of crane joints all have rotational structure to realize the rotation purpose on tetragonal four summits.
Below through embodiment the technical scheme of the utility model is elaborated, but the protection domain of the utility model is not limited to the following scope of putting down in writing.
The example structure of the light fixture that the utility model relates to is extremely shown in Figure 5 referring to Fig. 1.
This LED lamp device with safeguard structure comprises lamp stand 8, LED light fixture 4, solar cell 2, lift 7 and quadrangle crane 5 etc.
The last turning joint 1 of quadrangle crane is fixed on the lamp stand 8, and LED light fixture 4 is fixed on the intermediate active joint 50.
On lamp stand 8, be provided with chute 3, lower end turning joint 9 is connected with chute 3 through slide mass (lower end turning joint) 9, and it is up and down in chute 3 that elevating lever 6 drives slide mass 9.
The circuit module principle of the utility model is as shown in Figure 4, and module comprises battery, also comprises the battery electric quantity detector; The battery electric quantity detector is connected with lift with battery, LED light fixture; The battery electric quantity detector drives the up-down activity of lift according to the electric weight that detects battery, and the power of adjustment LED light fixture.
In one embodiment, when the battery electric quantity detector detected accumulator electric-quantity and reduces, lift descended the height of lower end turning joint, and the height of LED light fixture is descended; When said battery electric quantity detector detected the accumulator electric-quantity increase, lift rose the height of lower end turning joint, and the height of LED light fixture is risen.
The range of exposures of the utility model and the principle of effect are as shown in Figure 3.If the C point is the smallest height that the LED light fixture can drop to, its range of exposures is the c angle; The B point is the maximum height position that the LED light fixture can be raised to, and its range of exposures is the b angle.Can find out by figure; The LED light fixture is in B time of ordering and has farther higher position, and its range of exposures is very big, and this is fit to sun-drenched sunny weather very much; Accumulators store has sufficient electric power; It can give the enough energy of LED light fixture, the illumination that the LED light fixture therefore can be wider, and the LED light fixture has bigger benefit.But when electric weight is not enough; Under the situation that does not reduce illumination under the lamp, the height of LED light fixture descends, the minimum C point position that may be collapsed to; Can suppose that the electric weight of battery is minimum this moment; The illumination zone that light fixture can provide is the scope of c angle, and this scope is minimum, but is enough to provide the illumination of regulation illumination to the lamp lower area.If but light fixture at the A point, its irradiation area is a angle, can be found out by Fig. 3; Edge regions provides too much illumination in the room of street lamp for it; It can not provide farther field of illumination, and this lighting system is also inapplicable in some cases, obviously shines the situation of remote areas for needs; It is more desirable that light fixture is in the design that B orders, and light fixture is in the unique distinction that the B point embodies the utility model quadrangle crane just.
In the time of blowing and raining, can start lift, promote crane and rise, the LED light fixture is got in the crown top of burner chamber 100.The LED light fixture is able to avoid the attack infringement of external force and rainwater.
