1. Technical Field
The present invention relates LED lamps, and more particularly, to an LED lightbulb with an improved gain structure.
2. Description of Related Art
Living spaces nowadays are illuminated by various lamps. In spaces, lamps are positioned as needed and configured to emit light for providing brightness in the spaces. Hence, lighting equipment is important to living spaces, as the light it emits not only enhances the quality of the living spaces, but is closely correlated with the health of the human body and the human eye.
In general, basic lighting is intended to illuminate a space and thereby ensure an unblocked view thereof. Hence, the stability of the light emitted by basic lighting has a direct effect on the human eye. Also, there are growing concerns for the manufacturing process of lamps, raw materials used in the process, environmental protection-related issues regarding the recycling of the raw materials, and high power consumption of light.
Recently, there are some instances of unfavorable international coverage of the negative effect of conventional lamps on the human health and environmental protection. At present, the international community is replacing conventional lamps with LED lamps. LED lamps are absolutely free from problems with environmental protection and health hazards. Also. LED lamps excel conventional lamps in the brightness and stability of illumination, not to mention that LED lamps are extremely power-saving. Hence, LED lamps are very popular with consumers.
Since LED lamps generate heat when emitting light, dissipation of heat generated by an LED lamp is speeded up by ventilation holes formed on a housing of the LED lamp and a heat dissipating unit. However, insects are likely to intrude into the LED lamps through such ventilation holes to thereby cause short circuits to the LED lamps. Also, light-emitting dies of LED lamps are usually arranged in a matrix and thus fail to meet the need for a wide variety of lamp patterns (that is, patterns other than a matrix).
Considering the urgent need to overcome the above drawbacks of the prior art, the inventor of the present invention conducted studies and experiments continually, and eventually devised an improved structural design.
Examiners of related patent authorities are hereby requested to refer to the appended drawings and embodiments when looking into the structures, methods, objectives, and spirit of the present invention, so as to gain insight into the present invention.
An LED lightbulb with an improved gain structure, configured to improve LED lamp pattern design and arrangement of light-emitting dies, has a die-type LED lamp with the light-emitting dies desirably arranged and a structure for preventing insects from intruding into the lamp, including a base casing, a heat dissipating unit coupled with the LED lamp, meshes, and a transparent cover, and characterized in that the LED lamp has a middle portion defined with a matrix arrangement region for the light-emitting dies. Rows of the light-emitting dies are disposed at the periphery of the matrix arrangement region. The light-emitting dies disposed at the periphery of the matrix arrangement region are spaced apart from the light-emitting dies disposed within the matrix arrangement region, respectively. The meshes adhere to the base casing and correspond in position to the air holes, respectively, to prevent intrusion of insects and thereby protect the LED lamp against short circuits.
In conclusion, the present invention demonstrates novel effects, involves an inventive step, has never been published or applied, and has high industrial applicability. Hence, the applicant of the present invention hereby files a patent application with related patent authorities and expects that the related patent authorities will allow the patent application.
It should be noted that the above descriptions pertain to preferred embodiments of the present invention. All changes which are made to the preferred embodiments of the present invention according to the concepts thereof and bring about a desired function or effect without departing from the spirit embodied in the specification and drawings should be deemed falling within the scope of the present invention.
