Description

Shockproof heat-resistant LED projection lamp

Technical Field

The utility model belongs to the LED lamp field especially relates to a heat-resisting LED projecting lamp takes precautions against earthquakes.

Background

An LED projector is a lamp that specifies that the illuminance on the illuminated surface is higher than the ambient environment. The method is mainly used for large-area operation sites, mines, parks, flower beds, building exteriors, stadiums, overpasses and the like. Thus, almost all large area lighting fixtures used outdoors can be considered as floodlights.

The LED projection lamp consists of three parts, namely an optical part, a mechanical part and an electrical part. The optical components are mainly reflectors and light-shielding grids that confine light. The mechanical parts mainly comprise a shell, a focusing mechanism for fixing and adjusting the position of a light source, a bracket and a base for fixing the lamp and a part with angle indication for adjusting the projection direction of the light beam of the lamp. The electrical components are mainly ballasts, capacitors, triggers (provided according to the requirements of the light source), and the like.

The electrical components and part of the optical components need to dissipate heat in the working process, and the requirements cannot be met only by natural heat dissipation, so that heat dissipation elements need to be added. In addition, the mechanical parts are easily loosened due to vibration during use, and thus a shock absorbing function needs to be added.

Disclosure of Invention

For overcoming the not enough of prior art, the utility model aims at providing a heat-resisting LED projecting lamp takes precautions against earthquakes improves the radiating effect of projecting lamp, ensures that the LED projecting lamp normally works.

In order to achieve the above object, the utility model discloses a following technical scheme realizes:

a shockproof heat-resistant LED projection lamp comprises a light source protective cover, a protective pinch plate, a fixed plate and a support, wherein the light source protective cover is fixedly connected with the protective pinch plate through screws; the radiator comprises radiating fins, an outer frame, a tenon plate and a connecting plate, wherein the radiating fins are parallel to each other and fixed on the tenon plate, the outer frame is spliced with the tenon plate and fixed through the connecting plate, the radiating fins extend out of the outer frame, and slots matched with the radiating fins are formed in the bottom of the outer frame.

The frame top be equipped with the recess, tenon board both ends are equipped with the arch, the recess cooperatees with the arch.

The connecting plate is fixedly connected with the outer frame through a check bolt.

Still include fixed frame, fixed frame both sides pass through bolt, lock washer fixed with the fixed plate, fixed frame is embedded to have light source safety cover and protection buckle, is equipped with a plurality of rubber strips between light source safety cover, protection buckle and the fixed frame.

The rubber strip is of a tubular structure.

The fixed plate is a U-shaped plate.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses set up radiator and fan, with the inside heat discharge of projecting lamp, set up the power externally also reduce the inside thermal production of projecting lamp simultaneously. The radiating fins are of a structure extending out of the outer frame, so that the radiating area is increased, and the radiating efficiency is improved. The rubber strips are arranged to reduce the vibration between the light source protective cover and the protective pinch plate and between the protective pinch plate and the support, and to protect the internal optical elements and the internal electric elements. The rubber strip adopts a tubular structure, and the buffering stroke is prolonged. In addition, the reliability of the connection of the mechanical parts of the projection lamp is ensured by utilizing the anti-loosening bolt and the anti-loosening washer.
