Description

U type combined high-power electricity-saving lamp

Technical field

The utility model relates to a kind of lighting, specifically is a kind of U type combined high-power electricity-saving lamp that is applied to light projector or road lighting.

Background technology

At present, a part of power saving fluorescent lamps on the market, in order to satisfy the needs of brightness of illumination, the plug and the switch that must adopt a plurality of lamp sockets, a plurality of lamp body and cooperate with it, because the structure of this kind product and circuit are arranged, it is big not only to take up room, but also the inconvenience that causes installation, uses and keep in repair is simultaneously also attractive in appearance inadequately; Existing other a part of power saving fluorescent lamps on the market, a kind of combination U type fluorescent tube electricity-saving lamp is disclosed as Chinese patent 200720035013.8, wherein, combination U type fluorescent tube equidistantly distributes on circumference, though utilized U type fluorescent tube, but because the equal in length of each fluorescent tube, a lot of light are blocked by adjacent U type fluorescent tube, and luminous efficiency is not high.

The U type fluorescent lamp that tradition is generally used is generally circular arrangement, its arrangement mode requires the space bigger to road lamp lamp light source chamber, and general light fixture can't meet the demands, and this arrangement mode causes part light to be blocked, the loss of light is very big, and the light fixture utilization ratio is very low; It adopts E40 or E27 standard lamp head fixedly connected, and the weight of the overwhelming majority are the fluorescent tube part, so in actual applications, the fracture of lamp holder plastic often takes place, and the fluorescent tube fragmentation causes the product can't operate as normal, bring potential safety hazard to road lighting, and increase maintenance cost greatly.

The utility model content

In order to overcome above-mentioned deficiency, the utility model purpose be to provide a kind of easy for installation, be convenient to keep in repair or replacing and luminous efficiency height, U type combined high-power electricity-saving lamp elegant in appearance.

To achieve these goals, the technical solution adopted in the utility model is: U type combined high-power electricity-saving lamp, include fluorescent tube, lamp socket and circuit board, wherein, lamp socket is to be made of housing and cover plate, and housing adopts dismantled and assembled the connection with cover plate, and circuit board is located in the housing, it is characterized in that: described fluorescent tube is to be parallel to each other and spaced apartly to be constituted by a plurality of U type power saving fluorescent lampss, and the length of a plurality of U type power saving fluorescent lampss is increased to the centre gradually by both sides; Described housing is provided with the corresponding jack of two limbs with each U type power saving fluorescent lamps, and cover plate is provided with the electric power connecting mouth; The limb of described U type power saving fluorescent lamps is plugged on the housing in the corresponding jack.

The both ends of described housing one sidewall are provided with row's louvre respectively.

Described fluorescent tube is to be combined by eight U type power saving fluorescent lampss, and the housing of described lamp socket is provided with eight pairs and eight corresponding jacks of U type power saving fluorescent lamps.

The beneficial effects of the utility model: because the surface of housing is provided with the jack of paired equidistant distribution, realized the mounting means that U type fluorescent tube and lamp socket are pegged graft, thereby made things convenient for the maintenance or the replacing of each parts; Owing on housing, established louvre, in the process of work, help the heat that circuit board produced in the housing is distributed, thus the useful life of prolongation electric ballast and energy-conserving light source; Because fluorescent tube adopts knockdown structure, has not only saved the space, and has been convenient to installation and maintenance; Because it is unequal to face the length of U type power saving fluorescent lamps mutually, thereby has improved luminous efficiency.
