Abstract
The utility model discloses a light-emitting diode (LED) projection lamp with an adjustable condensation range, which comprises a lamp and a plurality of LEDs. The bottom of the lamp is internally provided with a plurality of reflecting elements; the LEDs are arranged in the reflecting elements; a condenser lens is arranged in front of each reflecting element; the reflecting elements and the condenser lenses oppositely move along the axis of the lamp in a back-to-back manner; and the lamp is provided with a device for driving the reflecting elements and the condenser lenses to oppositely move in a back-to-back manner. By adopting the technical scheme, the distance between the LEDs and the condenser lenses can be adjusted only by pushing a sliding plate to slide back and forth, so that emitted light rays can be regulated to make the light rays gathered in a target area and greatly improve the illuminating effect of the target area, and the application of military, fire protection and stage performance is met.
Description
Technical field:
The utility model relates to a kind of LED projecting lamp of regulating the optically focused range size.
Background technology:
The LED illuminating industry is an emerging industry, and it is subjected to people's attention deeply with its unique advantage.The LED light fixture has little etc. advantage of long-life, energy-conservation, high brightness, volume, and LED has color and brightness can be controlled, the characteristics that colour temperature is abundant simultaneously; compare with traditional gas-discharge lamp; the LED lamp does not contain toxic gas, and heavy metal such as also not leaded, mercury plays a protective role to environment.
Owing to have above-mentioned advantage, the LED lamp more and more is widely used, for example at national defence, fire-fighting and performance occasion projecting lamp commonly used, LED projecting lamp on the market all is that a large amount of light emitting diodes at will is being installed in light fixture, effect in conjunction with reflecting component is carried out projection illumination to the target location, but because the light that this LED shot-light penetrates disperses very much, other mechanism is not set regulates spotlight effect, a kind of reflector lamp of can only saying so, if the projection target has certain distance, this floodlight is difficult to reach desired illuminating effect.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, a kind of LED projecting lamp of regulating the optically focused range size to be provided.
For achieving the above object, the technical scheme that the utility model provides is: the LED projecting lamp that can regulate the optically focused range size, include light fixture and many light emitting diodes, be provided with many reflecting components in the bottom of light fixture, light emitting diode is configured in the reflecting component, the place ahead at each reflecting component all is provided with collector lens, and reflecting component becomes in opposite directions along lamp axis with collector lens and moves with opposing, light fixture be provided with drive reflecting component and optically focused saturating in opposite directions with the device of opposing motion.
The place ahead at reflecting component is provided with light conducting cylinder, and light conducting cylinder covers the outlet of reflecting component, and collector lens is located in the light conducting cylinder.
Described drive unit is made of eccentric wheel, motion bar and sliding panel, eccentric wheel is located at outside the bottom of light fixture, motion bar is in light fixture pierces into light fixture, sliding panel is located in the light fixture, one end of motion bar is connected with sliding panel, the other end cooperates with eccentric wheel, is set with back-moving spring on one section motion bar between eccentric wheel and the light fixture bottom.
After adopting technique scheme, slide before and after the sliding panel as long as promote, just can regulate the distance between light emitting diode and the collector lens, thereby realize the light that penetrates is regulated, make light-ray condensing in a target area, the illuminating effect of target area is greatly improved, and satisfies military affairs, fire-fighting and stage performance and uses.
Description of drawings:
Fig. 1 is the structure chart after the utility model LED projecting lamp is once regulated;
Fig. 2 is the structure chart after the utility model LED projecting lamp secondary is regulated;
Fig. 3 is the three-dimensional structure diagram of the utility model LED projecting lamp.
The specific embodiment:
Now elaborate the utility model in conjunction with the accompanying drawings:
The LED projecting lamp of the optically focused the regulated range size of present embodiment includes light fixture 1 and many light emitting diodes 2, be provided with many reflecting components 3 in the bottom of light fixture 1, light emitting diode 2 is configured in the reflecting component 3, be provided with light conducting cylinder 4 in the place ahead of reflecting component 3, light conducting cylinder 4 covers the outlet of reflecting component 3, front end at light conducting cylinder 4 is provided with collector lens 5, in light fixture 1, be provided with sliding panel 6, all light conducting cylinders 4 all are installed on the sliding panel 6, outside the bottom of light fixture 1, be provided with eccentric wheel 7, one motion bar 8 passes the light fixture bottom, the one end is connected with sliding panel 6, the other end is pushed down eccentric wheel 7, on the motion bar section between eccentric wheel 7 and the light fixture bottom, be set with back-moving spring 9, when needing to regulate the illuminating effect of projecting lamp, as long as rotate eccentric wheel 7, eccentric wheel 7 will outwards push up motion bar 8, sliding panel 6 and light conducting cylinder 4 are pushed outwards moving under the effect of motion bar 8, and collector lens 5 is realized the once adjusting of throw light away from light emitting diode 2, be rotated further eccentric wheel 7, under the effect of back-moving spring 9, motion bar 8 is pushed back, and sliding panel 6 and light conducting cylinder 4 are inwardly slided back, at this moment collector lens 5 is near light emitting diodes 2, thereby realizes the secondary of throw light is regulated.
The above-mentioned description of this LED projecting lamp being carried out with reference to embodiment is illustrative rather than determinate, therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
