The locking structure of the lens on the spotlight

Abstract

The invention belongs to the technical field of reflector lamp structures, and discloses a lock catch structure for a reflector lamp upper lens. The lock catch structure comprises a lamp body, the lens and an elastic fastener, wherein the lens is fastened on the lamp body through the elastic fastener. A flange is arranged at the bottom end of the lamp body. The elastic fastener comprises a base plate and at least two fastening lugs bent upwards at the periphery of the base plate. An opening through which light is allowed to be emitted out is formed in the base plate. Each fastening lug comprises a first fastener body and a second fastener body, wherein the first fastener body is used for fastening the lens, and the second fastening body is used for fastening the flange. According to the lock catch structure for the reflector lamp upper lens, due to the facts that the elastic fastener is fixed only through the flange arranged on the lamp body, and no additional structures need to be machined on the lamp body, the structure of the lamp body is greatly simplified, the design machining process of the lamp body is simplified, and the machining cost and the maintenance cost of the lamp body are greatly reduced. Furthermore, due to the fact that the opening through which the light is allowed to be emitted out is formed in the base plate, the influence of the elastic fastener on the lamp illumination effect is effectively avoided, the structure is simple, and practicability is high.

Description

technical field [0001] The invention belongs to the technical field of spotlight structures, and in particular relates to a locking structure of a lens on a spotlight. Background technique [0002] In the field of lighting technology, spotlights are widely used, such as MR16 spotlights, which are used in lighting fields such as tracking lighting, recessed ceiling lights, table lamps, chandeliers, landscape lighting, retail lighting and bicycle headlights. Body, lens and fixing piece, the lens is fixed on the lamp body through the fixing piece. [0003] Most of the fixing parts in the prior art are fixed on the lamp body in the following two ways: one is to process the internal thread and the external thread on the lamp body and the fixing part respectively, and then fix the fixing part on the lamp body through screw connection; One is to respectively process connection holes for screws on the lamp body and the fixing part, and then fix the fixing part on the lamp body throu...

Problems solved by technology

[0004] Both of the above two methods require additional processing on the lamp body for the mounting groove for accommodating the lens and the connection structure for connecting the fixing parts, which, on the one hand, is not conducive to the simplified design of the lamp body structure, and increases the design of the lamp body. The complexity of the processing process increases the design and processing cost of the lamp body; on the other hand, when the connection structure on the lamp body is damaged, the entire lamp body needs to be overhauled, and even the lamp body needs to be replaced due to the irreparable nature of the connection structure. , thus causing a great waste of resources and greatly increasing the maintenance cost of the lamp body
