Abstract
The invention is applicable to the technical field of lamp installation and discloses a high-power lamp which comprises a lamp cap, a lamp holder, a fixed seat, a radiating member, an elastic heat conduction piece and a casing with a recessed cavity. The fixed seat and the radiating member are fixed in the recessed cavity at intervals. The head of the lamp cap is connected with the radiating member through the elastic heat conduction piece, and the tail portion of the lamp base is connected with the fixed seat through the lamp holder. Vibration frequency of the lamp base is directly buffered through the radiating member and the elastic heat conduction piece, the amplitude of the lamp base is reduced to enable the lamp base to be in the micro vibration state or the non vibration state, damage of vibration to the lamp is reduced to a great extent, the requirement for lamp ship detection severe vibration is met, the service life of the lamp is prolonged effectively, and the use range of the lamp is effectively expanded. Meanwhile, heat dissipated by lighting of the lamp base is dissipated timely through the elastic heat conduction piece and the radiating member, the surface temperature of the lamp base is effectively reduced, and the service life of the lamp is effectively prolonged.
Description
Technical field
The invention belongs to lamp installation technical field, relate in particular to a kind of explosion-proof large-power lamp.
Background technology
Large-power lamp has higher luminous efficiency and good color developing because of it, and is widely used in the illumination in the places such as stadiums, exhibition center, megastore, industrial premises, square, street, station, harbour, boats and ships.
Traditional large-power lamp mounting structure comprises lamp holder, holder and housing mostly, lamp holder is fixed in housing by holder, and it is owing to there is no extra vibration damping radiator structure, so its vibration damping and heat radiation are substantially all realized by holder, like this, the effect of its vibration damping and heat radiation is just very poor.And because the working environment vibration in some place is larger, we know, violent vibration easily causes lamp holder or the loosening phenomenon such as lamp holder loose contact, lamp holder fragmentation that causes of holder, thereby cause the inefficacy of lamp luminescence, like this, greatly reduce the service life of light fixture, had a strong impact on client's use; Simultaneously, understandably, because the power of light fixture is larger, the heat of its generation is also just many, if can not in time heat be derived to heat radiation, lamp surface excess Temperature will easily cause the too fast damage of light fixture, thereby has shortened its service life, can not give full play to the effect of its illumination, cause the significant wastage of resource.
For addressing the above problem, in prior art, a kind of method of setting up a damping ring in the mounting structure of traditional large-power lamp is proposed to carry out vibration damping, particularly, one end connection fixing base of its lamp holder, the other end connects damping ring, being arranged on some and vibrating the effect that has played vibration damping in smaller place of damping ring, but practical application shows, in the larger place of vibration, the effectiveness in vibration suppression of damping ring is just very small, like this, violent vibration still can cause the Rapid Damage of light fixture, has had a strong impact on the service life of light fixture.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of explosion-proof large-power lamp is provided, vibration damping and radiating effect that it has improved light fixture, extended service life of light fixture.
